Recipe Overview

• Prep Time: 15 minutes
• Cook Time: 15 minutes
• Total Time: 30 minutes
• Servings: 6-8
• Yields: 1 casserole
• Dietary Type: Not specified

Ingredients

• 12 ounces fettuccine pasta
• 3 tablespoons olive oil
• 4-5 sliced white mushrooms
• 3 cups half-and-half
• ¼ cup butter
• 1 tablespoon garlic powder
• 1 tablespoon seasoning salt
• 1 tablespoon black pepper
• ¾ cup grated Parmesan cheese
• 2 boneless skinless chicken breasts
• 1 cup French’s French fried onions

Equipment Needed

• Large pot
• Large casserole dish
• Large saucepan
• Whisk

Instructions

1. Begin by preparing the chicken. You can bake, poach, or grill the chicken breasts until fully cooked. Once cooked, allow the chicken to cool slightly before slicing it into bite-sized strips. Set aside.

2. Cook the fettuccine pasta according to package directions until al dente. Drain the pasta thoroughly.

3. In the same pot used to cook the pasta, or in a large bowl, combine the cooked and drained fettuccine pasta, sliced mushrooms, sliced chicken, and olive oil. Toss gently to coat all ingredients evenly. Transfer the mixture to a large casserole dish.

4. Prepare the Alfredo sauce. In a large saucepan, pour in the half-and-half. Whisk in the garlic powder, seasoning salt, and black pepper. Bring the mixture to a light boil over medium heat, being careful not to let it foam over. Reduce the heat to low and simmer.

5. Slowly add the grated Parmesan cheese to the half-and-half mixture while continuously stirring with a whisk. Continue to stir until the cheese is fully melted and the sauce is smooth and creamy. Let the sauce simmer for 1 to 2 minutes, stirring occasionally.

6. Pour the prepared Alfredo sauce over the fettuccine pasta, chicken, and mushroom mixture in the casserole dish. Toss gently to ensure all the ingredients are evenly coated with the sauce.

7. Sprinkle the French’s French fried onions evenly over the top of the casserole.

8. Cover the casserole dish with aluminum foil or a lid. Bake in a preheated oven at 300 degrees Fahrenheit for 10 to 15 minutes, or until heated through and the French fried onions are lightly browned.

9. Remove the casserole from the oven and let it stand for a few minutes before serving.

10. Serve hot with a side salad and garlic bread for a complete and satisfying meal.

Expert Tips & Tricks

• Pre-Cook the Chicken: Save time by using leftover rotisserie chicken or pre-cooked grilled chicken strips. This also adds a different flavor profile to the dish.
• Don’t Overcook the Pasta: Al dente pasta holds its shape better in a casserole and prevents a mushy texture.
• Freshly Grated Parmesan: Using freshly grated Parmesan cheese will yield a smoother and more flavorful sauce compared to pre-shredded varieties.
• Prevent Sauce from Breaking: Ensure the heat is low when adding the Parmesan cheese to the half-and-half. High heat can cause the sauce to separate or become grainy.
• Spice it Up: Add a pinch of red pepper flakes to the sauce for a subtle kick of heat.
• Make Ahead: Assemble the casserole up to 24 hours in advance, but wait to add the French fried onions until just before baking to prevent them from getting soggy. Store the unbaked casserole covered in the refrigerator. Add 5-10 minutes to the baking time if baking directly from the fridge.
• Broil for extra flavor: If you want the fried onions to get extra crispy, broil on low for the last minute of cooking. Make sure you watch it carefully to prevent burning.

Serving & Storage Suggestions

Serve the Chicken Fettuccini Alfredo Casserole hot as a main course. It pairs well with a fresh green salad dressed with a light vinaigrette and warm garlic bread.

Storage: Leftovers should be stored in an airtight container in the refrigerator. They will keep for up to 3-4 days.

Reheating: Reheat individual portions in the microwave or larger portions in the oven at 350 degrees Fahrenheit until heated through. You may need to add a splash of milk or half-and-half to the sauce if it has thickened during storage.

Freezing: While the casserole can be frozen, the texture of the sauce may change slightly upon thawing. To freeze, allow the casserole to cool completely, then wrap it tightly in plastic wrap and aluminum foil. Freeze for up to 2 months. Thaw overnight in the refrigerator before reheating.
