Delicious Crockpot Chicken Spaghetti for Comforting Dinners

What You’ll Need:

For a foolproof Crockpot Chicken Spaghetti, gather these ingredients:

• 3 boneless, skinless chicken breasts (about 1 ½ pounds)
• 1 (10-ounce) can cream of mushroom soup
• 1 (10-ounce) can cream of chicken soup
• 1 cup chicken broth
• 1 medium onion, finely chopped
• 3 cloves garlic, minced (or 1 teaspoon garlic powder)
• 1 (12-ounce) box spaghetti pasta, broken in half
• 1 ½ cups shredded cheddar cheese
• 1 cup shredded mozzarella cheese
• ½ cup diced bell peppers (optional, for a little color and freshness)
• 1 teaspoon salt
• ½ teaspoon black pepper
• ½ teaspoon dried Italian seasoning
• Red pepper flakes, to taste (if you like a little heat)

No problem if you don’t have fresh garlic—I often use garlic powder for my Crockpot Chicken Spaghetti, and it’s just as flavorful. The cream of mushroom and cream of chicken soups are the backbone of that creamy texture, easily found in the regular canned soup aisle. Don’t be shy about using store brands here—they work great and keep things budget-friendly.

If you want to cut a bit of prep time, buy pre-chopped onions or even use frozen diced onions. I sometimes keep frozen bell peppers on hand so I can just toss them in without extra chopping. The cheese is where I add a personal touch—I use a blend of sharp cheddar along with mozzarella to get that gooey pull, but feel free to swap in Monterey Jack or whatever cheese you prefer.

Leftover Crockpot Chicken Spaghetti stores well in an airtight container in the fridge for up to four days. It reheats beautifully in the microwave or in a skillet over low heat, just add a splash of chicken broth to loosen it back up. Planning to freeze? Portion it out before adding pasta, because the noodles can get mushy when frozen. You can always cook fresh spaghetti and mix it in when reheating—easy and tasty.

This Crockpot Chicken Spaghetti uses ingredients you probably already have on hand because good cooking shouldn’t require a special trip to the store. It’s perfect for a cozy weeknight dinner and makes enough to feed a crowd without breaking the bank.

Let’s Cook It Together!

1. Start by prepping your chicken. Place your boneless, skinless chicken breasts at the bottom of your slow cooker. No need to brown or sear them—keeping it simple saves time and cleanup.
2. Add the aromatics next. Sprinkle your chopped onions and garlic over the chicken. The slow cooker will let those flavors slowly infuse the dish as it cooks.
3. Mix your creamy base. In a bowl, stir together the cream of mushroom soup, cream of chicken soup, and chicken broth. Pour this mixture evenly over the chicken and veggies.
4. Season wisely. Add salt, pepper, Italian seasoning, and a pinch of red pepper flakes if you like a little kick in your Crockpot Chicken Spaghetti.
5. Set it and forget it. Cover your slow cooker and cook on low for about 5 to 6 hours, or on high for 3 to 4 hours. I always prefer low and slow for the best texture and flavor.
6. Check your chicken. It should be tender and easy to shred with two forks. If your Crockpot Chicken Spaghetti looks a bit watery at this stage, don’t worry—that sauce thickens with the pasta and cheese later.
7. Cook the pasta separately. While your chicken is cooking, boil your broken spaghetti noodles just shy of al dente (about 1-2 minutes less than package instructions). They’ll finish cooking in the slow cooker.
8. Shred and stir. Once the chicken is done, shred it in the slow cooker. Then mix in the cooked spaghetti noodles, shredded cheddar, and mozzarella cheeses. Stir everything until melty and combined.
9. Final warm-up. Pop the slow cooker cover back on and cook on low for another 15-20 minutes. Your Crockpot Chicken Spaghetti will thicken to creamy perfection.
10. Taste and adjust. Give it a final taste test. Sometimes I like to add an extra sprinkle of cheese or a dash more seasoning. That’s the best part—make it yours.

From start to finish, this Crockpot Chicken Spaghetti takes me about 6 hours on low, but most of that time is hands-off. While it’s cooking, I chop some simple sides or prep a salad like this easy chicken grape salad for a fresh contrast. Trust me, your kitchen will smell incredible when dinner is ready—you’ll get that cozy, inviting aroma that tells you a good meal is waiting.

If your Crockpot Chicken Spaghetti looks a little soupy when you add the pasta, don’t panic. Just let it cook a bit longer with the lid off and it will thicken up nicely. I learned patience here makes all the difference.

How to Serve & Enjoy It!

This Crockpot Chicken Spaghetti shines when served with a simple green salad or steamed veggies to balance its creamy richness.

A crisp Caesar salad or a bowl of roasted broccoli pairs beautifully—adding fresh texture and color that brightens the plate.

I like to serve mine with a warm crusty bread or even garlic bread for dipping. The bread soaks up any leftover sauce, turning every bite into a comfort food moment.

This crockpot recipe makes a perfect one-pot chicken dinner for family nights, casual gatherings, or potlucks where you want something hearty without fuss.

Leftovers? They’re fantastic reheated the next day, but I also fold them into a casserole dish topped with extra cheese and bake for a bubbling, golden crust.

For holiday variations, I’ve added diced green chilies or a splash of hot sauce to give my Crockpot Chicken Spaghetti a little festive twist. When my guests try it, they can’t help but say, “This tastes like the ultimate comfort food pasta recipe!” It’s those moments sharing this simple meal that remind me of how food really brings people together.

Your Questions Answered

Can I make this Crockpot Chicken Spaghetti ahead of time?
Absolutely. You can prepare everything through the cooking stage, then cool and refrigerate it. Reheat on low in your slow cooker or on the stove, adding extra broth if needed. Just remember to add pasta fresh or cook and mix it in during reheating to avoid mushy noodles.

What’s the best substitute for cream of mushroom in this Crockpot Chicken Spaghetti?
If mushroom soup isn’t your thing, cream of celery or cream of chicken soup alone works well. I’ve also used homemade white sauce with great results.

Can I use frozen chicken breasts?
Yes, just add extra cooking time—plan for an extra hour or two on low. It’s a handy shortcut when you’re short on time but want a hands-off meal.

How do I make this Crockpot Chicken Spaghetti for fewer servings?
Simply halve all the ingredients and use a smaller slow cooker if you have one. Adjust pasta quantity to your portion needs.

Is this recipe gluten-free?
It’s easy to make gluten-free by using gluten-free pasta and ensuring your soups don’t have hidden gluten (most store brands label this clearly).

Can I add vegetables to the Crockpot Chicken Spaghetti?
Definitely! Bell peppers, mushrooms, or even spinach thrown in last 30 minutes make a nice addition. I sometimes add frozen peas for a pop of color and sweetness.

What if my Crockpot Chicken Spaghetti turns out too thick?
Stir in a bit of chicken broth or milk to loosen the sauce—little by little until it reaches your preferred creaminess.
