Ingredients

3-4 Chicken Breasts
1 can (10 oz) Diced Tomatoes with Green Chiles
1 can Cream of Chicken Soup
1 can Cream of Mushroom Soup
1 medium Onion, chopped
2 cloves Minced Garlic
1 teaspoon Italian Seasoning
8 oz Cream Cheese, cubed
1 ½ cups Cheddar Cheese, grated
8 oz Spaghetti noodles

Instructions

Step 1: In the slow cooker, combine the chicken breasts, diced tomatoes with green chiles, cream of chicken soup, cream of mushroom soup, chopped onion, minced garlic, and Italian seasoning. Cover and cook on high for 3-4 hours or on low for 6-8 hours.
Step 2: Remove the cooked chicken from the slow cooker and shred it using two forks. Return the shredded chicken back to the slow cooker.
Step 3: Add the cubed cream cheese and grated cheddar cheese to the slow cooker. Stir well to combine, then cover and cook on low for 20-30 minutes until the cheese has melted and the mixture is creamy.
Step 4: Meanwhile, cook the spaghetti noodles according to the package instructions until al dente. Drain and stir the noodles into the slow cooker mixture. Serve warm and enjoy.
