Essential Ingredients for Your Farmer’s Casserole
This section provides detailed ingredient notes, tips for best results, and smart substitution options to ensure your **breakfast casserole** turns out perfectly every time. You’ll find all exact measurements and full instructions in the printable recipe card at the end of this post.
- Frozen Hash Browns: For convenience and optimal texture, frozen shredded hash browns are ideal. They provide a delightful crispy edge while remaining tender within the casserole. Diced hash browns also work well if you prefer a different texture. The best part? There’s no need to thaw them beforehand; they go directly into the baking dish, absorbing the egg mixture as they bake to become perfectly tender and flavorful.
- Ham: This recipe shines with cooked, diced ham. It’s a fantastic opportunity to use up leftover holiday ham, ensuring no delicious morsel goes to waste. If you don’t have leftovers, store-bought cooked ham steaks (like Smithfield or Hatfield) are a convenient and equally flavorful option. Just dice them into small, bite-sized pieces for even distribution throughout the **ham and egg casserole**.
- Colby Jack Cheese: This cheese melts beautifully, creating a wonderfully gooey texture, and offers a mild, creamy flavor that complements the other ingredients without overpowering them. For the best melting and flavor, I highly recommend shredding your own cheese from a block. However, if convenience is key, pre-shredded Colby Jack or a similar blend will work. Great swaps include sharp cheddar cheese for a tangier kick, Pepper Jack for a touch of spice, or Monterey Jack for a milder, creamier profile.
- Eggs: You’ll need eight large eggs to create that wonderfully fluffy, custardy texture that holds the casserole together. Ensure they are whisked thoroughly with the milk and seasonings for an even distribution throughout the dish, which is key to a cohesive and well-set casserole.
- Evaporated Milk: This is a crucial ingredient for achieving the perfect richness and creamy consistency in your egg mixture. Found in the baking aisle, evaporated milk is thicker and more concentrated than regular milk. It adds a depth of flavor and prevents the casserole from becoming watery, which can often happen with standard milk due to its higher water content. For the best results, whole or 2% evaporated milk is recommended for optimal texture and taste.
- Green Onions: Sliced green onions add a burst of fresh, mild onion flavor and a vibrant pop of color to the casserole. They are not just a garnish; they contribute significantly to the overall taste, providing a subtle sharpness that balances the richness of the ham and cheese. If you’re not a fan, or don’t have any on hand, they can be omitted, but I highly recommend including them for that extra layer of flavor.
- Salt & Pepper: Simple yet essential. These basic seasonings enhance all the natural flavors in the casserole. Remember to season to taste, especially if your ham is particularly salty, as you may need to adjust the amount of added salt accordingly.
Pro Tip for the Perfect Bake
For the absolute best results and a beautifully evenly baked casserole, I strongly recommend baking this dish in a stoneware or ceramic baking dish. These materials conduct heat more consistently than glass, ensuring that your hash browns are tender and golden, and the eggs are perfectly set without the bottom browning too quickly or unevenly. If using a glass dish, keep a closer eye on the bottom of the casserole during the last 20 minutes of baking, as it may brown quicker due to the way glass conducts heat.
How To Master This Farmer’s Casserole: Step-by-Step Guide
Preparing this **overnight breakfast casserole** is incredibly straightforward, making it perfect for both novice cooks and seasoned chefs. Follow these simple steps for a truly delicious result that will have everyone asking for more:
Step 1: Prepare Your Baking Dish and Layer the Base.
Begin by generously spraying a 9 x 13-inch rectangular baking dish with non-stick cooking spray. This crucial step prevents sticking and makes for easier serving and cleanup. Next, evenly spread the frozen shredded hash brown potatoes across the entire bottom of the dish, forming a solid, uniform base. These hash browns will absorb the egg mixture and cook up beautifully, creating a tender and flavorful foundation for your casserole. Finally, sprinkle the diced cooked ham, shredded Colby Jack cheese, and sliced green onions uniformly over the hash brown layer. This ensures every bite is packed with a balanced combination of flavors and textures.
Step 2: Whisk Together the Egg Mixture.
In a large mixing bowl, crack the eight large eggs. Add the two 12-ounce cans of evaporated milk, along with ¼ teaspoon of salt and ¼ teaspoon of freshly ground black pepper. Using a whisk, beat the ingredients vigorously until they are thoroughly combined and slightly frothy. This thorough whisking ensures that the eggs, milk, and seasonings are perfectly incorporated, leading to a smooth, consistent, and flavorful custard base for your casserole, preventing any dry spots or unevenly cooked eggs.
Step 3: Combine and Refrigerate Overnight.
Carefully pour the whisked egg mixture evenly over the layered ingredients in the baking dish. Make sure the liquid permeates all the layers, reaching the hash browns at the bottom. Once poured, cover the baking dish tightly with aluminum foil or plastic wrap. This step is crucial for an **overnight breakfast casserole**! Place the covered dish in the refrigerator for at least 8 hours, or ideally, overnight. Allowing it to rest overnight not only makes for easy morning prep but also allows the hash browns to soften slightly and all the flavors to truly meld together, resulting in a richer, more cohesive, and deeply flavored casserole.
Step 4: Bake to Golden Perfection and Serve.
When you’re ready to bake, preheat your oven to 350°F (175°C). Remove the casserole from the refrigerator and uncover it. Bake for 55-65 minutes, or until the center is set and firm, and the top is beautifully golden brown and bubbly. A knife inserted into the center should come out clean, indicating that the eggs are fully cooked. Once baked, remove the casserole from the oven and allow it to stand for 5-10 minutes before slicing and serving. This resting period is essential as it helps the casserole set further, making it easier to cut into neat, delicious portions without falling apart.
Storage, Freezing, and Reheating Your Farmer’s Casserole
One of the many benefits of this **ham and hash brown breakfast casserole** is how well it stores and reheats, making it excellent for meal prepping or enjoying delicious leftovers throughout the week.
- Refrigerate: Any leftover **farmer’s egg casserole** should be stored in an airtight container in the refrigerator. Properly stored, it will stay fresh and delicious for up to 3 days, making it perfect for quick breakfasts or lunches.
- Freeze: To freeze, first allow the casserole to cool completely to room temperature. You can freeze it as a whole casserole, wrapped tightly, or in individual portions, which is great for quick, single-serving meals. Wrap it tightly in plastic wrap and then aluminum foil, or place individual slices in freezer-safe containers. It will keep well in the freezer for up to 2 months. Remember to thaw it completely in the refrigerator overnight before reheating for best results.
- Reheat: For reheating a whole casserole, cover it with foil and bake at 350°F (175°C) until warmed through, which typically takes about 30 minutes, depending on the thickness. For individual slices, you can microwave them for 1–2 minutes, or reheat in a toaster oven for a crispier edge, mimicking that freshly baked taste.
Delicious Additions & Variations for Your Farmer’s Casserole
This **hash brown breakfast casserole** is incredibly versatile, inviting you to customize it with your favorite flavors and ingredients. Feel free to experiment with these delicious additions and variations to make it uniquely yours:
- Farmer’s Egg Casserole with Sausage: For a different savory profile, replace the ham entirely or use a combination of both with cooked breakfast sausage or even leaner turkey sausage. Ensure the sausage is thoroughly cooked and crumbled before adding it to the casserole mixture to avoid any raw spots and to drain excess fat. This adds a wonderfully rich and often spicier depth.
- Hash Brown Breakfast Casserole with Peppers: Elevate both the color and flavor by incorporating finely diced bell peppers (any color!), mild green chiles, or even a can of drained Rotel tomatoes for a Southwestern flair. Sautéing these vegetables lightly before adding them can enhance their sweetness and prevent the casserole from becoming watery.
- Spicy Breakfast Bake: If you love a little heat to kickstart your morning, swap out the Colby Jack for Pepper Jack cheese. You can also add a pinch of crushed red pepper flakes, finely diced jalapeños (deseeded for less heat), or a dash of your favorite hot sauce to the egg mixture for a zesty and exciting kick.
- Vegetarian Version: Easily transform this into a delightful vegetarian **egg and hash brown casserole** by omitting the meat entirely. Instead, load it up with your favorite vegetables. Sautéed spinach (ensure it’s well-drained), mushrooms, zucchini, or even a handful of sun-dried tomatoes work wonderfully. Just be mindful not to overload with very watery vegetables like fresh tomatoes, as this can affect the casserole’s consistency.
- Bacon Breakfast Casserole: For a smoky, crispy twist, substitute the ham with plenty of crumbled cooked bacon. The smoky flavor of bacon pairs perfectly with the eggs and hash browns, creating a truly irresistible and classic breakfast combination.
- Mediterranean Inspired: For a sophisticated twist, add crumbled feta cheese, chopped Kalamata olives, and sautéed spinach. A sprinkle of oregano or fresh parsley would complete this vibrant flavor profile.
- Southwestern Style: Incorporate cooked black beans, corn, a dash of taco seasoning, and top with fresh salsa, sliced avocado, and a dollop of sour cream after baking for a flavorful Tex-Mex inspired meal.
Expert Tips for the Best Farmer’s Casserole
Achieving a perfectly cooked and delicious **ham, egg, and cheese casserole** is easy with these insider tips that will elevate your breakfast game:
- **Choose the Right Baking Dish:** As mentioned, using a ceramic or stoneware dish is highly recommended. These materials distribute heat much more evenly than glass, which can often lead to over-browning on the bottom before the rest of the casserole is cooked through.
- **Allow the Casserole to Rest:** Don’t rush to slice and serve immediately after removing it from the oven. Letting the casserole rest for 5-10 minutes allows the egg mixture to fully set and solidify, making for cleaner, more intact slices and preventing it from falling apart when served.
- **Shred Your Own Cheese for Superior Melt:** While pre-shredded cheese is convenient, it often contains anti-caking agents (like cellulose) that can prevent it from melting as smoothly and creamily. Shredding your own Colby Jack or cheddar cheese from a block will give you a superior, meltier texture and richer flavor.
- **Don’t Overmix the Eggs:** Whisk the egg mixture until just combined and slightly frothy, ensuring no streaks of egg white remain. Overmixing can incorporate too much air, which can lead to a tougher, more rubbery egg texture once baked.
- **Prevent a Watery Casserole:** Sticking with evaporated milk is key to preventing a watery end product. Additionally, if you decide to add fresh vegetables like mushrooms or zucchini, lightly sauté them first to remove excess moisture before adding them to the casserole.
- **Season to Perfection:** Always taste your ham before adding salt. If you’re using a very salty cured ham, you might want to reduce the added salt in the egg mixture slightly, and then adjust after baking if needed.
Farmer’s Casserole FAQs
Here are answers to some common questions about making this delightful **overnight farmer’s breakfast casserole**, ensuring you have all the information you need for a successful bake:
While it might be tempting, I strongly recommend sticking with evaporated milk for this recipe. Regular milk is significantly thinner and contains more water, which will result in a watery, less rich, and potentially rubbery casserole. Evaporated milk provides the essential creamy texture, richer flavor, and ensures the eggs set beautifully without breaking down.
Absolutely! While the combination of flavors with ham is classic and delicious in this **farmer’s breakfast bake**, you can certainly substitute it with your favorite breakfast meat. If you opt for cooked breakfast sausage (pork or turkey), crumbled bacon, or even diced cooked chicken, be sure to fully cook and drain any excess fat from them before mixing them into your casserole. This prevents the casserole from becoming greasy and ensures the meat is fully cooked.
The top of the casserole should appear beautifully golden brown and bubbly, and the edges should be slightly set. To be absolutely sure, gently jiggle the dish; the center should be mostly set, not liquidy. For a definitive test, insert a knife or a wooden skewer into the very center of the casserole. If it comes out clean, your **egg and hash brown casserole** is perfectly done. Avoid overbaking, as this can make the eggs dry and rubbery.
Yes, you absolutely can! While overnight chilling (8+ hours) allows for the best flavor melding and hash brown softening, you can assemble the casserole a few hours before baking. Just make sure it chills in the refrigerator for at least 2-3 hours to allow the eggs to start setting and the flavors to begin developing. You might notice the hash browns are slightly less tender if not soaked overnight, but it will still be incredibly delicious and a great time-saver.
Certainly! If you’re not feeding a large crowd, you can easily halve this recipe. Simply cut all ingredient quantities in half and use a smaller 8×8 or 9×9 inch baking dish. Remember to also adjust the baking time accordingly; start checking for doneness around 30-40 minutes by inserting a knife into the center.

Farmer’s Casserole
Author: Jaclyn
Equipment
-
9 x 13 Casserole Dish ceramic or stoneware recommended for even heating
Ingredients
- 6 cups frozen hash browns
- 2 cups diced cooked ham
- 1 ½ cups shredded Colby jack cheese
- 2 green onions sliced
- 8 large eggs
- 2 12-ounce cans evaporated milk
- ¼ teaspoon salt or to taste
- ¼ teaspoon black pepper
Instructions
-
Prep a 9×13-inch baking dish by generously spraying it with non-stick cooking spray to prevent sticking.
-
Spread the frozen hash browns evenly along the bottom of the casserole dish, forming a single, consistent layer. Then, evenly sprinkle the diced cooked ham, shredded cheese, and sliced green onions on top of the hash browns.
-
In a large mixing bowl, whisk together the eggs, evaporated milk, salt, and pepper until well combined and slightly frothy. Pour this egg mixture carefully and evenly over the layered ingredients in the baking dish, ensuring all components are moistened.
-
Cover the baking dish tightly with aluminum foil or plastic wrap. Place it in the refrigerator overnight (or for at least 2-3 hours) to allow the flavors to meld and the hash browns to soften slightly before baking.
-
When you’re ready to bake, preheat your oven to 350°F (175°C). Remove the casserole from the refrigerator and uncover it. Bake for 55-65 minutes, or until the center is set and firm, and the top is golden brown and bubbly. A knife inserted into the center should come out clean.
-
Remove the casserole from the oven and allow it to sit undisturbed for 5-10 minutes before slicing and serving. This resting period helps the casserole set, making it much easier to cut into perfect squares.
Notes
I recommend using a stoneware or ceramic baking dish since they heat more evenly than a glass baking dish, which can sometimes lead to an over-browned bottom. A glass baking dish can be used if needed, just keep in mind that the bottom of the casserole may brown quicker and adjust baking time or temperature slightly if necessary to prevent burning.
Refrigerate any leftover casserole in an airtight container for up to 3 days for best freshness. This makes it ideal for meal prepping throughout the week.
