A classic recipe to try is Slow Cooker Chicken Spaghetti. The Chicken cooks all day, and then the spaghetti casserole is assembled just in time for dinner.
My Slow Cooker Chicken Spaghetti is a must try! If you love a decadent pasta meal, this recipe checks all the boxes. Chicken spaghetti is a tex-mex style dish, loaded with cheese and a creamy dreamy sauce. It’s a great busy day meal to have in your back pocket.
Key Ingredients
Chicken: Boneless skinless chicken breasts have the best texture for pasta recipes like this.
Seasonings: Onion powder and garlic powder – no salt needed for the sauce ingredients have plenty of sodium.
Sauce: A magical blend of cream of mushroom soup, Rotel tomatoes, velveeta and cream cheese. It makes a thick sauce, and the flavors combine so well.
Spaghetti: Cooked spaghetti brings the whole dish together.
How to Make Slow Cooker Chicken Spaghetti
- Cook the chicken in the creamy Rotel and cheese mixture until tender.
- Shred the chicken right in the crockpot and stir to combine.
- Add cooked spaghetti, top with cheddar, and heat until melted and creamy.
Tips & Variations
Too thick? If the sauce is too thick after adding the pasta, stir in a splash of chicken broth or milk to loosen it.
Soup Swap: You can substitute cream of chicken soup for cream of mushroom if preferred.
Pasta Choice: Use thin spaghetti or angel hair pasta for a lighter texture, or swap in another pasta shape like penne or rotini.
Add Vegetables: Add diced bell peppers, mushrooms or onions for extra texture.
Spice Level: Use mild or hot Rotel, depending on your heat preference.
How to Serve Chicken Spaghetti
Sides: A fresh Caesar salad, steamed green beans or broccoli are a great choice for this pasta meal.
Bread: We always top our rotel chicken spaghetti meal off with garlic bread, or bread sticks – just like they do at restaurants.
Toppings: You can top each pasta serving with green onions, tomatoes and even a dollop of sour cream.
Can Rotisserie Chicken Be Used?
Yes, though you will want to add a cup of chicken broth and you can cut the cooking time in half.
Can uncooked pasta be added to a slow cooker?
Generally, no. The slow cooker does not get hot enough to cook the pasta properly. You’ll want to cook pasta on the stovetop and add it right before serving.
