1 (4 oz) can diced green chilies (optional, for heat)
8 oz cream cheese, softened
1 cup shredded mozzarella cheese
1 cup shredded cheddar cheese

Step-by-Step Instructions for Making Easy Crockpot Chicken Spaghetti

This is one of the easiest dishes to prepare. Follow these simple steps for chicken spaghetti recipes that will have your family begging for seconds:

Sauté the chicken: Heat the olive oil in a large skillet over medium heat. Add the chicken breasts or thighs and cook until browned on both sides, about 4–5 minutes per side. (If you prefer, you can skip this step and place the raw chicken directly in the crockpot.)
Prepare the sauce: In a medium bowl, combine the marinara sauce, diced tomatoes, green chilies, garlic powder, onion powder, and Italian seasoning. Stir to combine.
Layer the crockpot: Place the cooked or raw chicken at the bottom of the crockpot. Pour the sauce mixture over the chicken.
Cook: Cover the crockpot and cook on low for 6–7 hours or high for 3–4 hours. The chicken should be tender enough to shred easily with two forks.
Shred the chicken: After cooking, shred the chicken in the crockpot using two forks. Mix it well with the sauce.
Add the pasta: Break the uncooked spaghetti into smaller pieces and stir it into the crockpot. Make sure the pasta is submerged in the sauce.
Add the cheese: Sprinkle the shredded mozzarella and cheddar cheese over the pasta, then stir to combine. Let the cheese melt into the sauce and pasta for 10–15 minutes before serving.
Garnish and serve: Top with freshly chopped parsley or green onions for a burst of freshness.

Your Crockpot chicken spaghetti is ready to serve! Enjoy it with a side salad or roasted vegetables, and you’ve got a meal that’s easy, cheesy, and utterly delicious.

How to Make the Best Crockpot Cheesy Chicken Spaghetti

To ensure your crockpot cheesy chicken spaghetti turns out perfectly, here are some expert tips:

Use boneless, skinless thighs: Chicken thighs stay juicier and more flavorful than breasts, making them perfect for slow cooking.
Layer your ingredients: Start by adding the chicken at the bottom to ensure it cooks through and remains tender.
Break the pasta into smaller pieces: This helps the pasta cook evenly and absorb all the delicious sauce.
Stir occasionally: While the crockpot does most of the work, it helps to give the pasta a quick stir once it’s in the pot to prevent sticking.
Add extra cheese: Feel free to add more mozzarella or cheddar if you want an extra cheesy finish!
