INGREDIENTS

Chicken: You’ll need a pound of boneless, skinless chicken breast.

Pasta: This casserole calls for 1 pound of penne pasta.

Cheese: The most important ingredients are freshly grated mozzarella and parmesan cheese.

Roux: This creamy roux consists of butter, fresh garlic, flour and half and half.

Seasoning: Season up this tasty dish with nutmeg, salt and pepper.

HOW TO MAKE CHICKEN ALFREDO CASSEROLE

STEP ONE: Begin by preheating your oven to 360 degrees F. Cook the penne pasta in a large pot of boiling salted water for 3 minutes less than the package indicates. Drain the pasta and return it to the pot. Season the bite-sized chicken pieces with salt and pepper and fry them in a large pan with heated oil over medium heat. Once done cooking, remove the chicken pieces and add them to the pot with the pasta.

STEP TWO: In the same pan, melt 3 tablespoons of unsalted butter and add the garlic cloves. Cook the garlic for one minute and then stir in the flour and mix until it becomes a paste/roux. Continue by adding a large pour of half and half to the roux whisking constantly. Then pour in the remaining half and half and whisk making sure there are no lumps. Bring the roux to a simmer, stirring constantly for 2-3 minutes until it thickens.

STEP THREE: Once thickened, add the nutmeg, pepper and grated parmesan cheese. Stir the mixture and season it with salt to taste. Mix the sauce with the cooked penne and chicken along with half of the shredded mozzarella cheese.

TIPS FOR SUCCESS

  • Be sure to cook the pasta 3 minutes less than written on the package to avoid it being overcooked once the casserole has finished cooking.
  • If the bechamel sauce becomes lumpy you can blend it with an immersion blender until it’s smooth.
  • You can add vegetables like spinach or broccoli. These fit very well. Blanche the broccoli before adding. You can also cook the broccoli with the pasta, just add to the pasta the last 5 minutes of cooking time.
  • Crispy bacon adds a nice flavor too. Cook your bacon, crumble it, and add the bacon along with the rendered fat to the sauce.

If you want to get creative, there’s lot that can be done to enhance this casserole. I love to add spinach or blanched broccoli to the mix before baking. You can also cook the broccoli with the pasta by adding it to the boiling pot in the last 5 minutes of cooking time.

HOW LONG DOES CHICKEN ALFREDO CASSEROLE LAST?

Allow this Chicken Alfredo Casserole to cool before storing it in the fridge. It will last for 3-4 days when stored properly. When you’re ready, you can simpy reheat it in the oven or the microwave. If you end up with extra leftovers you can always wrap them in foil and freeze them. I like to wrap up individual servings to pull out for a quick lunch. One thing is for sure though, these leftovers never last too long in my house.
