Step-by-Step Instructions
- Prepare: Preheat the oven to 400 degrees Fahrenheit.
- Sautee: Heat a large pan on medium heat and add ¼ cup of butter. Once the butter melts, add the chicken and cook it until it is no longer pink and has slightly browned. Scoop out the chicken and add the onions and mushrooms and cook until they're soft, crispy, and the mushrooms have shrunk significantly. Add the chicken back in and remove it from the heat.
- Cook the pasta: Cook the pasta in a large pot following the instructions on the package.
- Make the sauce: Add ¼ cup of butter to a small pot on low heat. Once melted, add the flour and constantly stir until paste-like, about 1 minute. Slowly add the warm milk and increase the heat to medium-high. Stir vigorously until the mixture has slightly thickened, about 5 minutes. Remove from heat and add the garlic powder, salt, and pepper. Stir in 3 cups of mozzarella until melted, then the spinach, and then pour the sauce into the pan and mix with the chicken mixture.
- Bake: Transfer the cooked pasta to a 9x13 baking dish, pour the sauce mixture over it, sprinkle it with the remaining 1 cup of mozzarella, and bake uncovered on the middle rack for 10-15 minutes or until the cheese starts to melt and slightly golden.
Kitchen Tools You'll Need
- Frying Pan: A large pan will be used to make the pasta sauce.
- Pot: A large pot will be needed to cook the pasta noodles.
- Baking Dish: The pasta bake is baked in a 9x13 baking dish.
- Knife: You'll need a knife to chop the chicken, onions, and mushrooms.
- Cheese Grater: You'll need a cheese grater to shred the cheese.
- Measuring Spoons and Cups: These are used to measure the ingredients.
Storage and Leftovers
Once cooled, store any leftovers covered with tinfoil in the fridge for up to 5 days. You can also freeze this pasta bake in an airtight container(s) for up to 3 months and defrost and reheat in the microwave.
Expert Tips
- Don't overcook the noodles. Cook the pasta noodles a few minutes less than the package says because after boiling the pasta it still needs to bake and you don't want to overcook it because it'll become mushy.
- Fix sticky noodles. After draining the noodles, if they start sticking to each other just rinse them with some water and they will easily release from one another.
- Opt for block mozzarella. Pre-shredded mozzarella is fine, but if you shred it yourself, it melts better.
Alternative Ingredients
- Rotisserie Chicken: To make this recipe even easier, you could swap cooking the chicken for some shredded rotisserie chicken.
- Ricotta Cheese: To make this recipe even creamier, consider adding in blobs of ricotta cheese before topping with the mozzarella.
- Light Cream: To make this extra creamy, swap the milk for light cream such as half and half (10%).
- Parsley: Garnish with fresh parsley for fresh flavor that'll cut some of the heaviness from the dish.
