Ingredients for Crockpot Chicken Spaghetti

Fresh ingredients and pantry staples help create the best crockpot chicken spaghetti recipe.

Chicken thighs, spaghetti, onion, carrots, parsley, celery, garlic, tomato sauce, Italian seasoning, chicken broth, parmesan cheese, salt, pepper.
  • Chicken thighs: You’ll need 3 pounds of skinless chicken thighs. We’ll shred the chicken before serving so feel free to use bone-in chicken thighs or boneless chicken thighs.
  • Vegetables: Diced carrots, celery, and onion add a perfect medley of flavor and texture.
  • Garlic: Freshly minced garlic enhances the flavor of the sauce.
  • Tomato sauce: Plain canned tomato sauce with the addition of simple spices makes the tastiest homemade spaghetti sauce.
  • Chicken broth: A liquid is needed to make the sauce more “saucy” and cook the pasta. Use low sodium chicken broth or Instant Pot chicken broth if you have it.
  • Spices: Italian seasoning, salt, and pepper.
  • Spaghetti: You can use regular, whole wheat, or gluten-free spaghetti.
  • Fresh herbs: Sprinkling freshly chopped herbs like parsley, dill, or basil at the end really complements the pasta.

Tips for Best Results

Here are 4 simple tips for making the best chicken spaghetti in crock pot.

  • If you find spaghetti too starchy: Reduce broth by 2 cups when cooking chicken in crockpot, then cook spaghetti separately and add to the crockpot with chicken. Pasta cooked in sauce can make this dish a bit starchy but we don’t mind, I like one pot convenience.
  • Don’t overcook: Spaghetti, especially gluten free spaghetti, will become mushy if overcooked. And if chicken is cooked for too long it will be dry and tough.
  • Liquid at the end is fine: If your noodles and chicken are done and there’s still some liquid, that’s OK. The spaghetti will absorb it as it sits.
  • Use chicken thighs: Bone-in or boneless chicken thighs are more flavorful. Be sure to remove the skin, otherwise it will be fatty.

  • Add cheese: For an extra cheesy sauce, add 1-2 cups of shredded cheese at the end. I personally like cheddar cheese or mozzarella cheese.
  • Add cream cheese: If you like a creamier sauce then adding 4 ounces of cubed cream cheese at the end will do the trick.
  • Pasta: Use what you have in your pantry whether it be linguine or a short pasta like penne or elbow macaroni.
  • Chicken: Again, use what you have! Boneless skinless chicken breasts work well, or save time and add shredded leftover rotisserie chicken (cook for 2 hours).
  • Add bell peppers: Dice up a red, orange, or yellow bell pepper and toss it in with the other vegetables for more color and flavor.
  • Use Rotel: If you’re a fan of spice, add a can of Rotel with green chilies instead of tomato sauce.
  • Marinara sauce: Tomato sauce and marinara sauce can be used mutually. Marinara sauce is thinner, and great for pasta.

What to Serve Crockpot Chicken Spaghetti with?

Healthy pasta recipes are great on their own, and for our busiest days we just dish up and enjoy.

Sometimes it’s nice to have something a little extra, so I whip up a side dish while the noodles cook.

Can I Make It Ahead of Time?

Yes. If you are starting crockpot chicken spaghetti in the morning, before work, cook on low heat for 6-8 hours. In the evening all you have to do is shred chicken, add spaghetti, parmesan, and herbs, then serve.

To make a few days in advance, chop veggies and store in the fridge for up to 2 days.

How to Store

Store: Transfer leftovers to an airtight container and store in the fridge for up to 3 days.

Freeze: I don’t like freezing spaghetti because pasta doesn’t thaw well. If you want to avoid leftovers, I recommend cutting the recipe in half.


Does chicken and spaghetti need to be covered in liquid in crockpot?

Chicken has to be submerged in liquid in the crockpot, which will be quite easy as there is lots of broth. Most of spaghetti but not all has to be in the liquid. We will stir one more time at the end to make sure top strands are cooked.

Is it better to cook chicken on high or on low heat in crockpot?

Chicken in the crockpot is cooks better on low heat. It doesn’t matter much for chicken thighs because they are more fatty but for chicken breasts, low setting is better.

How do I keep chicken from drying out in crockpot?

For tender, juicy chicken cook on low heat, don’t overcook, and make sure it’s covered in liquid.

How do I fix bland crockpot chicken spaghetti?

I’ll add more parmesan cheese, red pepper flakes, and other cheeses at the end. Adjust seasonings to taste by adding more salt and pepper, a pinch of onion powder, garlic powder, paprika, or oregano.

Can I make it in Instant Pot?

Yes! Follow my Instant Pot spaghetti recipe.

    OMG! This recipe is really good. My family loved it. I did add 3/4 of a brick of cream cheese.
    Really, really good. Thank you

  2. I have a question. I’m making this tomorrow for a potluck, I have one hour between adding the pasta and the finished meal. If I use heart shaped pasta is it possible to leave the pot on low to cook more slowly so the pasta doesn’t overcook?

    1. No, low won’t help. Pasta will still get cooked in hot liquid. I recommend to add pasta 30 minutes before serving, then it should be good. Enjoy!

        This was delicious. I ended up cooking the pasta separately and just adding it to the pot to heat up. Worked well. Thank you for another great recipe!

  3. 5 stars
    Question: can I use pasta other than spaghetti? Like elbow macaroni, or even something larger? And if yes, what would be the changes in cooking time, etc.? Thanks!

    1. Yes, you can try! I would cook any pasta shape an initial 3o minutes, check for doneness and either go longer or ready to serve.

  4. 5 stars
    This recipe is a keeper for my husband and myself. I used chicken breast, and regular tomato sauce vs low sodium, but otherwise followed the recipe ingredients (which I don’t usually do). I am going to try Rotel tomatoes and more onions next time…maybe a different noodle. Not because I didn’t like the spaghetti, but because I think the recipe is flexible enough to change around.

    My chicken was partially frozen when i put it in the crock pot, so i started out on ‘high’ for two hours, then lowered to cook the rest of the time on ‘low’.

    We will be enjoying the left overs later this week 🙂
