Ingredients
- 1.5 cups whole wheat pasta (225g uncooked weight. You can use any short pasta like penne, rotini, or farfalle. Whole wheat pasta not only adds a lovely texture but also a boost of fiber.)
- 1 cup diced bell peppers (I opted for a colorful blend of red and yellow peppers, which add both sweetness and visual appeal. Green bell peppers are a great alternative if preferred.)
- 1/2 cup diced onion (Red onion provides a slightly milder, sweeter bite, but white or yellow onions will work just as well to build a flavorful base.)
- 1 bunch green onions (Finely chopped, these offer a fresh, delicate onion flavor that brightens the entire dish and adds a vibrant green garnish.)
- 2 cups cooked shrimp (Ideal for using up leftover cooked shrimp from a seafood platter. If starting fresh, buy pre-cooked shrimp for convenience, or quickly sauté raw shrimp until pink and opaque. Ensure they are peeled and deveined.)
- 1/2 cup light Alfredo sauce (Using a light version significantly reduces the calorie and fat content while still delivering that classic rich, creamy texture and taste.)
- 2 Tbsp light ranch dressing (This is our secret ingredient! It introduces a unique tangy, herbaceous complexity that truly elevates the Alfredo sauce beyond the ordinary.)
- 2 Tbsp grated fresh Asiago cheese (Asiago cheese lends a wonderful nutty and slightly sharp flavor profile. If Asiago isn’t available, grated Parmesan cheese is a perfectly acceptable and delicious substitute.)

Instructions
-
To begin, bring a large pot of lightly salted water to a vigorous boil. Add your whole wheat pasta and cook according to the package instructions until it reaches an al dente consistency – tender yet still firm to the bite. Once cooked, drain the pasta thoroughly and set it aside to cool slightly. Simultaneously, preheat your oven to 350°F (175°C) and lightly spray a 9×13 inch casserole dish with cooking spray to prevent sticking.
-
Prepare your vegetables by dicing the bell peppers, onion, and green onions. Transfer these vibrant, freshly cut ingredients into a generously sized mixing bowl. To this bowl, add your pre-cooked shrimp and the drained pasta. Now, introduce the creamy elements: pour in the light Alfredo sauce and the light ranch dressing. Stir all the components together meticulously, ensuring that the pasta, shrimp, and vegetables are thoroughly and evenly coated with the rich and tangy sauce. Proper mixing ensures a consistent flavor in every bite.
-
Carefully transfer the entire shrimp and pasta mixture from the large mixing bowl into your prepared 9×13 inch casserole dish, spreading it out into an even layer. Once distributed, generously sprinkle the grated fresh Asiago cheese (or your chosen Parmesan substitute) over the top. This layer of cheese will melt into a luscious, golden-brown crust, adding another layer of texture and flavor to the dish.
-
Place the casserole dish into your preheated oven and bake for approximately 25 minutes. The casserole is ready when the sauce is bubbly around the edges and the cheese on top is beautifully melted and lightly golden. This baking period allows the flavors to fully meld together and ensures the dish is heated through uniformly.
-
Once baked to perfection, remove the casserole from the oven and allow it to rest for a few minutes before serving. This brief resting period helps the sauce to set slightly, making it easier to portion out. This recipe generously yields 6 servings, with each portion amounting to about 1 1/3 cups. For those interested in nutritional tracking, each serving (excluding any additional vegetables for simplicity) contains approximately: Calories: 186, Fat: 3.5g, Saturated Fat: 1.3g, Carbohydrates: 28.8g, Fiber: 4g, Sugars: 2g, Protein: 9.8g.

Expert Tips for Crafting the Perfect Shrimp Alfredo Casserole
To ensure your Shrimp Alfredo Pasta Casserole consistently turns out perfectly, consider these helpful and practical tips:
- Optimal Pasta Choice: While whole wheat pasta is recommended for its enhanced nutritional benefits and slightly nutty flavor, feel absolutely free to use your preferred pasta shape. Short pasta varieties like penne, rotini, farfalle, or even classic elbow macaroni will all work splendidly. The key is to cook your pasta al dente, as it will continue to absorb liquid and cook slightly further when baked in the oven.
- Shrimp Preparation Excellence: If you’re not utilizing pre-cooked shrimp, ensure you quickly sauté fresh, raw shrimp in a little olive oil with a touch of minced garlic until they turn pink and opaque. It’s crucial not to overcook them at this stage, as shrimp can become rubbery. If using frozen cooked shrimp, always remember to thaw them completely and pat them dry with paper towels to prevent excess moisture from diluting your sauce.
- Elevating the Flavor Profile: For an extra layer of gourmet flavor, consider adding a tiny pinch of red pepper flakes to the sauce mixture for a subtle, delightful kick. A dash of garlic powder, onion powder, or a blend of Italian seasoning can also enhance the overall aromatic depth. Freshly cracked black pepper is always a welcome addition right before serving.
- Cheese Variations to Explore: While Asiago cheese offers a wonderfully unique nutty and slightly sharp dimension, a high-quality grated Parmesan cheese is a classic and equally delicious substitute. For those who enjoy an extra creamy, stretchy top, a sprinkle of fresh mozzarella cheese along with the Asiago or Parmesan could be a truly decadent touch.
- Boosting Vegetable Content: This casserole serves as an excellent canvas for incorporating additional vegetables. Consider quickly sautéing some fresh spinach until wilted, or blanching broccoli florets or asparagus tips, and then folding them into the mixture alongside the bell peppers and onions. Just be mindful to cook down any vegetables with high water content (like spinach) to prevent the casserole from becoming watery during baking.
Delightful Serving Suggestions
While this hearty Shrimp Alfredo Pasta Casserole stands proudly as a complete meal on its own, it also pairs beautifully with a few simple, complementary side dishes:
- Crisp Green Salad: A light, refreshing green salad dressed with a tangy vinaigrette offers a wonderful contrast, cutting through the richness of the creamy Alfredo sauce.
- Garlic Bread or Crusty Artisan Loaf: No pasta dish is complete without something to soak up every last drop of that delectable sauce. Warm garlic bread or a slice of crusty artisan bread is perfect for this purpose.
- Steamed Vegetables: For an additional boost of nutrients and fresh flavors, serve alongside simple steamed broccoli, green beans, or even roasted asparagus.
Storage and Reheating Made Easy
Leftovers of this Shrimp Alfredo Pasta Casserole are just as delicious, if not more so, than the initial serving. To store, simply transfer any remaining casserole into an airtight container and refrigerate for up to 3-4 days. For reheating, you have a couple of convenient options: individual portions can be quickly microwaved until heated through. Alternatively, for larger portions or to retain a crispier topping, cover the casserole dish with aluminum foil and bake in a preheated oven at 300°F (150°C) for 15-20 minutes, or until thoroughly warmed. If the sauce appears a little thick during reheating, a splash of milk or broth can be stirred in to restore its creamy consistency.
The Ingenious Blend of Light Alfredo and Ranch
You might be curious about the somewhat unconventional combination of light Alfredo sauce and light ranch dressing in this recipe. This pairing is, in fact, truly ingenious! The light Alfredo serves as the familiar, comforting creamy base that everyone loves, while the light ranch dressing introduces a subtle yet distinct tang and a delightful herbaceousness. This unexpected addition elevates the flavor profile far beyond a standard Alfredo sauce. It imparts a zesty brightness that wonderfully balances the richness of the dish, preventing it from feeling heavy and making each bite more exciting and complex, yet remarkably approachable.
