Ingredients You Need

Chicken and pasta

• 2 pounds boneless skinless chicken breasts
• 12 ounces spaghetti, broken in half (regular, whole wheat, or gluten free all work)

Sauce base

• 1 can (10.5 ounces) cream of chicken soup
  • Use low sodium if you watch salt.
• 1 can (10.5 ounces) cream of mushroom soup
  • Swap with a second can of cream of chicken if you dislike mushrooms.
• 1 can (10 ounces) Rotel diced tomatoes with green chiles, undrained
  • Use mild for kids, original for a little heat, hot if you like spice.
• 1 cup chicken broth
  • Use low sodium boxed broth or water with bouillon.
• 4 ounces cream cheese, softened and cubed
  • Full fat melts smoother, but light cream cheese still works.

Cheese and flavor

• 2 cups shredded cheddar cheese, divided
  • I like sharp cheddar; pre-shredded saves time and still tastes great here.
• 1 cup shredded mozzarella cheese
• 1 small yellow onion, finely diced
• 2 cloves garlic, minced (or 1 teaspoon garlic powder as a shortcut)
• 1 teaspoon kosher salt, plus more to taste
• 1 teaspoon black pepper
• 1 teaspoon smoked or regular paprika
• 1 teaspoon Italian seasoning
• 1 tablespoon olive oil or melted butter

Optional mix ins

• 1 cup sliced mushrooms
• 1 cup diced bell pepper
• 1 cup frozen peas or mixed vegetables

Equipment

• 6 quart slow cooker or larger
• Medium pot for boiling spaghetti
• Tongs or two forks to shred chicken
• Measuring cups and spoons
• Cutting board and knife
• Mixing spoon or spatula

Quick Tips & substitutions

• Use rotisserie chicken and cut the slow cooker time in half since you only need to heat and meld flavors.
• Swap cream of chicken and cream of mushroom with cream of celery if you prefer a lighter flavor.
• Use gluten free spaghetti and gluten free condensed soups to keep the Classic Crockpot Chicken Spaghetti Recipe gluten friendly.
• Stir the pasta into the sauce right before serving so it stays tender and not mushy.
• Spray the slow cooker with cooking spray so the cheesy sauce releases easily.
• Cut cream cheese into small cubes so it melts evenly into the sauce.
• Add extra broth if the sauce looks too thick after cooking; add more cheese if it looks too thin.
• Use pre-shredded cheese to save time; this recipe forgives the anti-melty coating.
• Keep the lid closed during cooking so the slow cooker holds heat and cooks evenly.
• Taste and adjust salt at the end since canned soups and broth vary in sodium.

How to Make Classic Crockpot Chicken Spaghetti Recipe

Step 1: Prep the slow cooker and aromatics

Spray the inside of your slow cooker with nonstick spray or rub it with a thin layer of olive oil. Add the diced onion, garlic, and any optional mushrooms or bell peppers. Drizzle with the tablespoon of olive oil or melted butter and toss to coat.

Step 2: Add the chicken and seasonings

Place the chicken breasts on top of the vegetables in a single layer. Sprinkle salt, pepper, paprika, and Italian seasoning over the chicken. This step builds flavor from the bottom up, so season generously.

Step 3: Mix the sauce

In a medium bowl, combine cream of chicken soup, cream of mushroom soup, Rotel with all its juices, and chicken broth. Stir until the mixture looks smooth. Add the cubed cream cheese and half of the shredded cheddar and all of the mozzarella, then stir again; the cheese does not need to melt yet, just distribute.

Step 4: Pour and cook

Pour the sauce mixture over the chicken in the slow cooker, covering it completely. Cover with the lid. Cook on low for 4 to 6 hours or on high for 2.5 to 3.5 hours, until the chicken shreds easily with a fork.

Step 5: Shred the chicken and smooth the sauce

When the chicken feels tender, remove the breasts to a plate or cutting board. Shred them with two forks into bite sized pieces. Stir the sauce in the slow cooker until the cream cheese and cheese melt fully and the sauce looks smooth and creamy, then return the shredded chicken and stir again.

Step 6: Cook the spaghetti

About 20 minutes before you plan to eat, bring a large pot of salted water to a boil. Add the spaghetti and cook it 1 to 2 minutes shy of package directions so it stays slightly firm. Drain the pasta well so extra water does not thin the sauce.

Step 7: Combine pasta and sauce

Add the drained spaghetti directly into the slow cooker. Use tongs to toss the pasta with the chicken and sauce until every strand looks coated. Sprinkle the remaining cheddar cheese over the top, cover, and let it sit on warm for 5 to 10 minutes so the cheese melts.

Step 8: Taste, garnish, and serve

Taste the Classic Crockpot Chicken Spaghetti Recipe and adjust salt and pepper if needed. Garnish with chopped fresh parsley or green onions if you like a little color. Scoop into bowls and serve hot while the sauce stays creamy and stretchy.

Recipe Variations

• Gluten free: Use gluten free spaghetti and gluten free condensed soups; thin the sauce with a splash more broth if it thickens too much.
• Lower carb: Swap spaghetti with cooked spaghetti squash strands or zucchini noodles added at the end just to warm through.
• Spicier: Use hot Rotel, add a pinch of cayenne, or stir in diced pickled jalapeños.
• Veggie loaded: Add extra mushrooms, bell peppers, peas, or spinach during the last 30 minutes.
• Extra cheesy: Stir in an extra half cup of cheddar and a handful of Parmesan at the end.
• Dairy lighter: Use reduced fat cream cheese and part skim mozzarella, and skip the final cheese topping.
• Kid friendly mild: Use mild Rotel or plain diced tomatoes and cut the paprika in half.

Ways to Serve Classic Crockpot Chicken Spaghetti Recipe

• With a simple green salad and ranch dressing.
• Alongside garlic bread or buttered toast.
• With steamed broccoli or green beans on the side.
• With a fresh fruit salad for a lighter contrast.
• In meal prep containers with a side of roasted vegetables.

Storage Success

Store leftover Classic Crockpot Chicken Spaghetti Recipe in an airtight container in the fridge for up to 4 days. Add a splash of milk or broth when you reheat it so the sauce turns creamy again. Reheat in the microwave in short bursts or on the stove over low heat while you stir often. Freeze portions in freezer safe containers for up to 2 months, then thaw in the fridge overnight before reheating.
