This Weeknight Chicken Pasta is a quick dinner idea that transforms simple ingredients into a creamy, satisfying meal. Perfect for busy families.

Ingredients

• 1.5 lbs boneless skinless chicken breasts (about 3 medium breasts)
• 12 oz spaghetti or angel hair pasta
• 1 can (10.5 oz) condensed cream of chicken soup (or cream of mushroom)
• 1 can (10 oz) diced tomatoes with green chilies (Rotel), undrained
• 1 cup low-sodium chicken broth
• 1/2 cup whole milk or heavy cream
• 2 cups shredded sharp cheddar cheese
• 1/2 cup grated Parmesan cheese
• 1 small yellow onion, finely diced
• 3 cloves garlic, minced
• 1 teaspoon onion powder
• 1 teaspoon paprika
• 1/2 teaspoon dried oregano
• 1/2 teaspoon dried thyme
• Salt and freshly ground black pepper to taste
• 2 tablespoons unsalted butter
• Fresh parsley, chopped, for garnish

Instructions

Step 1

Start by preparing your ingredients. Dice the onion finely; the smaller the dice, the more it will melt into the sauce, leaving you with flavor without chunky bits. Mince the garlic cloves. Shred the cheddar cheese from a block if possible—pre-shredded cheese often contains anti-caking agents that can prevent smooth melting. Set everything within easy reach. This mise en place ensures a smooth cooking process, especially when using a slow cooker where you’ll add ingredients in stages.

Step 2

In a 6-quart or larger slow cooker, place the chicken breasts in a single layer at the bottom. Season them generously with salt, pepper, onion powder, paprika, oregano, and thyme. This dry rub will infuse the chicken with flavor as it cooks. The paprika adds a subtle smokiness and a beautiful amber color to the final sauce.

Step 3

In a medium bowl, whisk together the condensed cream of chicken soup, diced tomatoes with their juices, chicken broth, and milk. Pour this mixture over the chicken, making sure the chicken is mostly submerged. The soup base provides creaminess and body, while the tomatoes add acidity to balance richness. The liquid will seem thin now but will thicken as it cooks and later when you add the cheese.

Step 4

Cover the slow cooker and cook on LOW for 3 to 4 hours, or on HIGH for 1.5 to 2 hours. The chicken is done when it reaches an internal temperature of 165°F and shreds easily with a fork. Cooking times vary based on your slow cooker and the size of the chicken breasts. Avoid opening the lid too often, as each peek releases heat and extends cooking time.

Step 5

When the chicken is tender, remove it to a cutting board and let it rest for a few minutes. Use two forks to shred the chicken into bite-sized pieces. Meanwhile, turn the slow cooker to HIGH if it isn’t already. Add the shredded chicken back into the pot along with the butter, stirring gently to combine. The butter enriches the sauce and adds a silky mouthfeel.

Step 6

Now it’s time to cook the pasta. While the chicken is being shredded, bring a large pot of salted water to a boil. Cook the spaghetti according to package directions until al dente—usually about 8 to 10 minutes. Be careful not to overcook, as the pasta will continue to soften slightly when added to the slow cooker. Drain the spaghetti well, but do not rinse it; the starch left on the pasta helps thicken the sauce.

Step 7

Add the drained spaghetti to the slow cooker and toss gently with tongs to coat every strand with the creamy sauce. Then, slowly sprinkle in the shredded cheddar and Parmesan cheeses while stirring continuously. The residual heat from the sauce will melt the cheese into a luscious, velvety sauce. If the sauce seems too thick, you can add a splash of warm chicken broth or milk to reach desired consistency.

Step 8

Let the pasta sit in the slow cooker on WARM for 5 to 10 minutes to allow the flavors to meld. Taste and adjust seasoning with salt and pepper if needed. Serve hot, garnished with fresh chopped parsley for a pop of color and freshness. This dish is best enjoyed immediately, but leftovers can be stored in an airtight container in the refrigerator for up to 3 days.

For best results

• To prevent the pasta from becoming mushy, cook it separately and add it only at the end. The slow cooker's prolonged heat can turn spaghetti into a starchy mess if left in too long. By cooking the pasta al dente and combining it just before serving, you ensure a perfect texture that holds up beautifully even as leftovers. If you prefer a one-pot approach, you can add uncooked pasta during the last 30 minutes of cooking, but you'll need to increase the liquid by about 1 cup and stir occasionally to prevent sticking.
• For the best flavor, use freshly shredded cheese from a block. Pre-shredded cheeses are coated with cellulose or potato starch to prevent clumping, which also inhibits smooth melting. This can result in a grainy sauce instead of the silky, cohesive cheese sauce we're aiming for. Take the extra minute to shred your own cheddar and Parmesan—it makes a noticeable difference in both texture and taste.
• If you don't have cream of chicken soup, you can make a quick substitute by whisking together 1 cup of milk, 1 tablespoon of all-purpose flour, and 1 teaspoon of chicken bouillon paste. Cook this mixture over medium heat until thickened, then use it as a 1:1 replacement. This homemade version allows you to control the sodium and avoid any preservatives, giving you a cleaner flavor profile.
• To add a bit of heat and depth, consider using a can of Rotel (diced tomatoes with green chilies) or adding a pinch of cayenne pepper and a dash of smoked paprika. The subtle spiciness cuts through the richness of the cheese and cream, making each bite more exciting. For a milder version, use regular diced tomatoes and omit any chili flakes.
• Leftovers can be easily reheated on the stovetop or in the microwave. If the pasta has absorbed too much liquid and seems dry, add a splash of milk or chicken broth while reheating and stir gently. The sauce will loosen up and regain its creamy consistency. Store leftovers in an airtight container for up to 3 days, but note that the pasta will continue to soften over time.
• For a gluten-free version, use gluten-free spaghetti and ensure your cream of chicken soup is certified gluten-free. Many brands offer gluten-free options, or you can make the substitute mentioned above using gluten-free flour. The cooking time for gluten-free pasta may vary, so check the package and cook until just al dente.

Variations

• Creamy Mushroom Chicken Pasta: Swap the cream of chicken soup for cream of mushroom soup and add 8 oz of sliced cremini mushrooms sautéed in butter. The earthy mushrooms complement the creamy sauce beautifully. You can also use a mix of wild mushrooms for a more gourmet touch. This variation is perfect for vegetarians (use vegetable broth) or anyone craving a deep umami flavor.
• Spicy Tex-Mex Chicken Spaghetti: Add 1 teaspoon of chili powder, 1/2 teaspoon of cumin, and a diced jalapeño (seeds removed for less heat) to the sauce. Use pepper jack cheese instead of cheddar for an extra kick. Top with fresh cilantro, diced avocado, and a squeeze of lime juice before serving. This version brings a fiesta to your dinner table and pairs wonderfully with a side of black beans.
• Lightened-Up Version: Use low-fat cream of chicken soup, skim milk, and reduced-fat cheese to cut calories and fat. Increase the chicken to 2 lbs for extra protein. You can also add steamed broccoli florets or spinach stirred in at the end for added nutrients. The flavor remains satisfying while being more waistline-friendly.
• Protein-Packed Chicken and Bacon Pasta: Cook 4 slices of bacon until crispy, then crumble. Add the bacon along with the shredded chicken. The smoky, salty bacon amplifies the savory notes. For extra protein, use whole wheat or legume-based pasta. This variation is a hit with kids and adults alike, delivering a hearty meal that feels indulgent.
• Dairy-Free / Vegan Adaptation: Replace the cream of chicken soup with a dairy-free cream of mushroom soup (or a homemade cashew cream: 1 cup soaked cashews blended with 1 cup water). Use vegan cheddar shreds and nutritional yeast instead of Parmesan. Omit the butter or use vegan butter. The sauce will still be creamy and delicious, and the dish becomes completely plant-based.
