HOW TO MAKE SLOW COOKER CHICKEN SPAGHETTI STEP-BY-STEP:
Check out the quick visual guides below. For full instructions and ingredients, see the printable recipe card at the end.
Step 1: Spray the bottom of the slow cooker with cooking spray. Add chicken to the slow cooker and season with salt, pepper, Italian seasoning, garlic powder, and onion powder. Add both cans of cream of mushroom soup, diced tomatoes, chicken broth, and smoked paprika. Stir to combine and cook on low for 4-6 hours, or on high for 3-4 hours. (cooking time will depend on the thickness of your chicken breasts)
Step 3: About 20 minutes before chicken is done, cook spaghetti according to package directions until al dente. Drain and set aside.
Step 4: Remove chicken from slow cooker and shred with two forks. Return shredded chicken to slow cooker along with the cooked spaghetti. Stir gently to combine.
Step 5: Add both shredded cheeses and stir until melted. Taste and adjust seasoning. Serve hot, garnished with chopped fresh parsley, if desired.
STEP 6: In a large skillet over medium-high heat, brown ground beef and onion until the beef is no longer pink, about 6-8 minutes. Drain the excess grease off.

PRO TIP:
Don’t overcook your spaghetti noodles since they’ll continue to soften when mixed with the hot chicken mixture in the slow cooker. Al dente is perfect for the best texture!
