Ingredients You Need

• 1.5 to 2 pounds boneless, skinless chicken breasts or thighs (thighs stay juiciest)
• 1 small yellow onion, diced (swap 1 teaspoon onion powder when you need a shortcut)
• 3 cloves garlic, minced (or 1 teaspoon jarred minced garlic)
• 1 can cream of chicken soup, 10.5 ounces (use low sodium if you prefer)
• 1 can cream of mushroom soup, 10.5 ounces (swap with a second cream of chicken if you avoid mushrooms)
• 1 can diced tomatoes with green chiles, 10 ounces, undrained (Rotel brings the perfect kick; choose mild for less heat)
• 1 cup low-sodium chicken broth
• 4 ounces cream cheese, cubed and softened (optional for extra creamy sauce)
• 2 cups shredded sharp cheddar cheese, divided (pre-shredded works fine)
• 1 teaspoon kosher salt, plus more to taste
• 1/2 teaspoon black pepper
• 1 teaspoon smoked paprika or regular paprika
• 1/2 teaspoon garlic powder
• 1/2 teaspoon onion powder if not using fresh onion
• 12 ounces spaghetti, broken in half (use gluten-free spaghetti if needed)
• 1 tablespoon unsalted butter or olive oil for tossing the pasta
• Optional add-ins: 1 cup sliced mushrooms, 1 diced bell pepper, 1/4 teaspoon red pepper flakes, chopped parsley for garnish

Equipment:

• 5 to 6 quart slow cooker
• Large pot and colander for pasta
• Tongs and two forks for shredding
• Measuring cups and spoons

How to Make Classic Crockpot Chicken Spaghetti Recipe

Step 1: Load the slow cooker (5 minutes)

• Stir the cream of chicken soup, cream of mushroom soup, diced tomatoes with green chiles, chicken broth, paprika, garlic powder, onion powder, salt, and pepper in the slow cooker.
• Nestle the chicken into the sauce and top with the diced onion and minced garlic.

Step 2: Cook the chicken (Low 3 to 4 hours or High 1.5 to 2 hours)

• Cook on Low for 3 to 4 hours or on High for 1.5 to 2 hours.
• Check that the chicken reaches 165 F and shreds easily with two forks.

Step 3: Shred and enrich the sauce (10 minutes)

• Transfer the chicken to a plate and shred it into bite-size pieces.
• Stir the cream cheese and 1 cup cheddar into the hot sauce until smooth.
• Return the shredded chicken to the slow cooker and stir to coat.

Step 4: Cook pasta and combine (15 minutes)

• Boil the spaghetti in salted water until 1 to 2 minutes shy of al dente.
• Drain, toss with butter or olive oil, and fold the pasta into the slow cooker sauce.
• Taste and adjust salt and pepper.

H3 Optional pasta-in-slow-cooker method (20 to 30 minutes)

• Break the dry spaghetti in half and stir it into the hot sauce after shredding the chicken.
• Switch to High, cover, and cook 20 to 30 minutes, stirring every 8 to 10 minutes so the pasta does not clump.
• Add a splash of broth if the sauce tightens too much.

Step 5: Melt cheese and rest (5 to 10 minutes)

• Sprinkle the remaining 1 cup cheddar over the top, cover, and let it melt.
• Rest 5 minutes so the sauce thickens and clings to the noodles.
• Garnish with parsley and serve.

Tips & Common Mistakes

• Salt smartly and taste at the end when cheese and soup add salt.
• Choose thighs when you want extra juicy chicken.
• Add cream cheese after the chicken cooks so the sauce stays smooth.
• Undercook pasta by 1 to 2 minutes to keep a nice bite.
• Stir pasta often if you cook it in the slow cooker to prevent clumps.
• Keep the slow cooker under two-thirds full so heat circulates well.
• Use mild Rotel for less heat or add red pepper flakes for a kick.
• Slice or shred chicken into larger pieces for better texture.
• Thin a tight sauce with a splash of broth or milk before serving.
• Check doneness early on your first run since slow cookers run hot or cool.

Variations I've Tried

• No-canned-soup version: whisk 1.5 cups broth, 1 cup milk, 2 tablespoons cornstarch, and the spices; pour that in place of the soups.
• Bacon ranch: add 4 slices cooked crumbled bacon and 1 tablespoon dry ranch seasoning; swap half the cheddar with Monterey Jack.
• Southwest spin: add 1 teaspoon cumin, 1 cup corn, 1 cup black beans, and use pepper jack.
• Buffalo style: stir in 1/4 cup hot sauce and 1 teaspoon ranch seasoning; finish with a little blue cheese.
• Mushroom lover: add 2 cups sliced mushrooms and 1 teaspoon Worcestershire.
• Lighter take: use Neufchatel cream cheese or 1/2 cup plain Greek yogurt; stir the yogurt off heat to keep it silky.
• Gluten-free: use gluten-free spaghetti and undercook by 2 minutes; toss with oil before mixing in.
• Low carb: roast spaghetti squash and fold the strands into the sauce at the end.

How to Serve

Twirl big bowls and top them with extra cheddar, parsley, and black pepper. Add a crisp green salad with lemon vinaigrette to balance the creamy sauce. Garlic bread or Texas toast makes a perfect sidekick and wipes every last bit of sauce from the bowl. I also set out hot sauce and pickled jalapeños for the heat lovers at the table.

Make-Ahead and Storage

• Make-ahead: cook the sauce and chicken up to 3 days in advance; cool, cover, and refrigerate. Cook fresh pasta on serving day and combine.
• Fridge: store leftovers in an airtight container for up to 4 days.
• Freezer: cool fully, portion into freezer-safe containers, and freeze for up to 3 months. For best texture, freeze sauce and chicken without pasta, then add fresh pasta after reheating.
• Reheat: warm gently on the stovetop over medium with a splash of milk or broth; stir often. You can also microwave in short bursts, stirring between rounds, until hot and creamy. Oven method works too; cover with foil and heat at 325 F until steamy.

• 1 cup sliced mushrooms

Instructions

 

1. In a 5- to 6-quart slow cooker, stir together the cream of chicken soup, cream of mushroom soup, diced tomatoes with green chiles, chicken broth, paprika, garlic powder, onion powder (if using), salt, and pepper.
2. Nestle the chicken into the sauce, then sprinkle the diced onion and minced garlic over the top.
3. Cover and cook on Low for 3 to 4 hours or on High for 1.5 to 2 hours, until the chicken reaches 165°F and shreds easily with two forks.
4. Transfer the cooked chicken to a plate and shred it into bite-size pieces using two forks.
5. Stir the cream cheese and 1 cup of the shredded cheddar into the hot sauce in the slow cooker until smooth and melted.
6. Return the shredded chicken to the slow cooker and stir to coat it in the creamy sauce.
7. Bring a large pot of salted water to a boil. Cook the spaghetti until 1 to 2 minutes shy of al dente, then drain well.
8. Toss the drained spaghetti with the butter or olive oil, then gently fold it into the chicken and sauce in the slow cooker. Taste and adjust salt and pepper as needed.
9. Sprinkle the remaining 1 cup cheddar cheese over the top. Cover and let stand for 5 to 10 minutes, until the cheese melts and the sauce thickens slightly.
10. Garnish with chopped parsley if desired and serve hot.

1. After the chicken is cooked and shredded, stir the shredded chicken back into the sauce and switch the slow cooker to High.
2. Break the dry spaghetti in half and stir it into the hot sauce, making sure it is submerged as much as possible.
3. Cover and cook for 20 to 30 minutes, stirring every 8 to 10 minutes to prevent the pasta from clumping or sticking.
4. If the sauce becomes too thick or the pasta absorbs too much liquid, add a splash of chicken broth to loosen it to your desired consistency before serving.
