Let me start by saying my husband requested that I make this recipe over my usual chicken pasta recipe that I’ve been making for 10 years!! I was appalled. But honestly I can’t even blame him. This creamy Chicken Spaghetti recipe is a pasta lover’s dream. Tender chicken breast and spaghetti pasta are coated with a luscious cream sauce, then baked to perfection with extra cheese on top! And this casserole is made with simple pantry and refrigerated ingredients. I don’t know about you but I always seem to have a box of spaghetti noodles hanging out in my cabinet. If you do need to make a quick store run, make sure you grab two of whatever item you need, because trust me you’ll want to add this one to your weekly dinner rotation!
When you read the words “Chicken Spaghetti” I’m sure you were thinking how on earth do those two foods go together? Well friend, let me ease your mind. This is not the traditional spaghetti sauce recipe that you’re probably familiar with. Chicken spaghetti is made with a creamy, cheesy, super flavorful cream sauce that coats tender chicken and spaghetti noodles. Tangy Rotel tomatoes are also added to give it an extra pop of flavor and to balance the creaminess of the dish. The mixture is then placed in a casserole dish and baked until it’s gooey and bubbly around the sides. Great, now I’m sitting here drooling just thinking about it again!
How to Make Chicken Spaghetti – Step by Step Photos
Preheat the oven to 375°F. Using a sharp knife, carefully fillet each chicken breast into two thinner cutlets. Here is a great tutorial on How to Cut Chicken Breasts Into Cutlets by Serious Eats. Heat a large deep skillet over medium heat and add 1 Tbsp olive oil. Add the four chicken cutlets to the skillet and cook on each side until golden brown and cooked through (about 7-10 minutes total). Remove the chicken to a clean cutting board, and allow it to rest.
While the chicken is cooking, bring a large pot of water to a boil over high heat. Add 1/2 Tbsp of salt to the water, then add 8 oz. of spaghetti pasta, and boil until the pasta is tender (or al dente). Drain the pasta in a colander.
While the pasta is cooking, start making the sauce. In the same skillet that the chicken was cooked in, heat 1/4 cup salted butter over medium-high heat. Add 1 diced onion and 2 minced garlic cloves. Sauté for 3-4 minutes or until onion is translucent.
Sprinkle 1/4 cup of flour into the skillet and stir with the onion and garlic. Cook for 2-3 minutes, stirring occasionally, until flour starts to turn golden brown. Slowly pour 2 cups of chicken broth into the skillet and stir to fully dissolve the flour from the bottom of the skillet. The flour will start to thicken the sauce when it returns to a simmer.
Add 1/2 tsp salt, 1/4 tsp black pepper, 1/2 tsp Italian seasoning, 1/2 cup cheddar cheese, 1/2 cup mozzarella cheese, and 1 cup of heavy cream to the skillet. Stir until the cheese is melted and the sauce is smooth.
Now chop the cooked chicken breasts into smaller ½ inch pieces.
Turn the heat off the skillet and add 1 can of drained diced tomatoes with green chiles, the chopped chicken, and the cooked spaghetti to the pan. Mix until combined.
Add the chicken spaghetti mixture to a 9×13” casserole dish. Top with the remaining 1/2 cup of cheddar cheese and 1/2 cup of mozzarella cheese.
Bake the casserole in the preheated oven for 25 minutes, or until bubbly around the edges and the cheese is melted on top.
Serving Suggestions
Serve this chicken casserole with some crusty bread. It would also pair well with a simple side salad to keep dinner simple and easy. With that being said, me and my family totally enjoyed this dish by itself…no extra sides needed for us!
