Ingredients
- 2 small boneless skinless chicken breasts
- 2 teaspoons Italian seasoning
- Salt and pepper, to taste
- 2 tablespoons olive oil
- 4 tablespoons butter
- 1 small yellow onion, diced
- 3 cloves garlic, minced
- 4 tablespoons flour
- 1 ½ cups chicken broth
- ¾ cup milk
- 4 oz. cream cheese, softened
- 1 cup cheddar cheese, shredded
- 10 oz. diced tomatoes and green chilies
Instructions
- Step 1: Season the chicken breasts with Italian seasoning, salt, and pepper. Heat olive oil in a large skillet over medium heat and cook the chicken until golden and cooked through, about 6-7 minutes per side. Remove from the pan and set aside to cool.
- Step 2: In the same skillet, melt butter and sauté diced onion until soft and translucent, about 3-4 minutes. Add minced garlic and cook for another minute until fragrant.
- Step 3: Stir in the flour and cook for 1-2 minutes to form a roux. Gradually whisk in chicken broth and milk, stirring constantly until the sauce thickens and becomes smooth.
- Step 4: Add softened cream cheese and shredded cheddar cheese to the sauce. Stir until the cheeses melt completely and the sauce is creamy.
- Step 5: Chop the cooked chicken into bite-sized pieces and return to the skillet. Add the diced tomatoes and green chilies, stirring to combine everything well. Simmer for 5 minutes to heat through and meld flavors.
- Step 6: Cook spaghetti noodles separately according to package instructions until al dente. Drain and add the noodles to the skillet with the chicken mixture, tossing gently to coat evenly with the sauce.
- Step 7: Serve warm, garnished with extra cheese or fresh herbs if desired.
