- 1 pound pasta any kind of pasta you have in your pantry
- 2 tablespoons olive oil
- 1 pound chicken breasts boneless, skinless, chopped in small 1 inch pieces
- salt and pepper to taste
- 2 tablespoons butter
- 1 large onion chopped
- 5 cloves garlic minced
- 1 teaspoon oregano
- 1 teaspoon basil
- ½ teaspoon red pepper flakes
- 1 cup chicken broth low sodium or no sodium added
- 28 ounces diced tomatoes 1 can
- 2 cups Mozzarella cheese shredded
Cook the pasta according to package instructions in a pot of boiling salted water.
Preheat oven to 375°F.
In a large skillet, heat olive oil over medium heat. Add the chicken and season chicken with salt and pepper. Cook the chicken until no longer pink, about 5 minutes.
Add the butter to skillet and melt. Stir in onions and cook for 3 to 5 minutes until the onion soften and become translucent. Add garlic and saute for another 30 seconds until aromatic.
Season with more salt and pepper if needed, then add the oregano, basil, oregano and red pepper flakes. Stir in the chicken broth and bring to a boil, scraping all the brown bits. Add crushed tomatoes and simmer for 5 minutes.
Transfer the cooked pasta to a 9x13-inch casserole dish, pour chicken tomato sauce over the pasta and a cup of the mozzarella cheese, then toss well. Sprinkle the remaining mozzarella cheese over the top of the casserole.
Transfer the casserole dish the the oven and bake for about 15 to 20 minutes, just until the cheese melts and gets bubbly.
- Pasta. Cook just shy of al dente since it will keep cooking in the oven. Mushy pasta is not the vibe.
- Chicken. Both breasts and thighs work. Thighs give more flavor, breasts keep it lean. Cut into small pieces for faster cooking.
- Cheese. Shredding your own mozzarella makes a difference. It melts smoother than the bagged kind.
- Veggie boost. Add sautéed mushrooms, spinach, zucchini, or peppers if you want to sneak in more vegetables.
- Make ahead. Assemble and refrigerate up to 24 hours before baking. Add 10 to 15 minutes to bake time.
- Storage. Keep leftovers in the fridge for 3 to 4 days or freeze for up to 2 months. Reheat in the oven until hot and bubbly.
