Ingredients
- Chicken: I like to use boneless chicken breasts to make chicken pasta in the slow cooker, but you could use chicken thighs if you prefer. Just make sure to trim off any excess fat.
- Italian Seasoning: This adds great flavor to the dish. If you don't have Italian seasoning on hand, use a blend of dried oregano, rosemary, and basil.
- Sea Salt: You can adjust the salt to your liking. I use about a teaspoon per pound of chicken.
- Black Pepper: Freshly ground black pepper adds the perfect zing.
- Rotel Tomatoes: A can of Rotel is an easy way to add extra spice and flavor to the sauce without extra prep time. Be sure not to drain off any liquid before adding them to the slow cooker.
- Broth: You can use store-bought or homemade chicken broth in this crock pot chicken spaghetti recipe.
- Half and Half (or Heavy Cream): This helps to create a richer, creamier sauce. If you don't have half and half on hand, heavy cream works just as well. You could also use whole milk.
- Cream Cheese: Adds some creamy richness to the dish. Be sure to cut it into cubes so that it melts evenly.
- Spaghetti Noodles: You'll need about 16 ounces of dry spaghetti noodles for this pasta recipe. Since we cook the pasta separately, almost any size or shape of pasta you like will work.
- Cheddar Cheese: I recommend sharp cheddar. You could also use mozzarella cheese, Colby jack cheese, or even Velveeta cheese.
- Parmesan: Use a block of parmesan that you grate yourself for the most flavor.

FAQs
Is it OK to put raw chicken in slow cooker?
Yes it is safe to put raw chicken in the slow cooker. The low setting on your slow cooker will help to ensure that the chicken is cooked through and reaches a safe internal temperature before serving.
Can I put frozen chicken in a slow cooker?
I strongly advise against putting frozen chicken in a slow cooker when making this creamy crockpot chicken spaghetti or any other recipe.
The primary concern with cooking frozen chicken in a slow cooker is the potential for bacterial growth. Bacteria thrive in temperatures ranging from 40°F to 140°F, which is commonly referred to as the “danger zone.”
When you place frozen chicken in a slow cooker, it takes longer for the internal temperature of the meat to reach the safe temperature of 165°F, allowing bacteria to grow and potentially cause foodborne illness.
Slow cookers are designed to cook food at low temperatures over an extended period, which can exacerbate the risk of bacterial growth when working with frozen meat.
This is because it can take several hours for the frozen chicken to thaw to room temperature and then additional time for it to reach a safe internal temperature. During this time, the chicken may linger in the danger zone for too long, allowing bacteria to multiply rapidly.
Besides the risk of bacterial growth, slow cooking frozen chicken can also result in uneven cooking. The outer layer of the chicken may cook at a faster rate than the center, leading to dry, stringy meat on the outside and undercooked meat in the center.
