Garlic Butter Chicken Spaghetti in Creamy Three-Cheese Sauce 🍗🧀🍝

Golden garlic butter chicken bites served alongside spaghetti coated in a creamy Velveeta, mozzarella, and Parmesan sauce. Prep: 10 minutes | Cook: 20 minutes Servings: 4

Ingredients

2 large boneless, skinless chicken breasts, cut into bite-size cubes
12 ounces spaghetti
3 tablespoons butter, divided
2 tablespoons olive oil
4 garlic cloves, minced
½ teaspoon salt, plus more to taste
½ teaspoon black pepper
½ teaspoon Cajun seasoning
2 tablespoons chopped parsley, plus extra for garnish
¼ cup grated Parmesan, divided
½ cup heavy cream
1 cup cubed Velveeta
½ cup shredded mozzarella
Reserved pasta water, as needed

Instructions

Cook spaghetti in salted water until al dente. Reserve 1 cup pasta water, then drain.
Season chicken with salt, pepper, and Cajun seasoning.
Heat olive oil and 2 tablespoons butter in a large skillet over medium-high heat. Add chicken in a single layer and cook for 6–8 minutes, turning occasionally, until golden and the centers reach 165°F (74°C).
Reduce heat to medium-low. Add garlic and cook for 30 seconds. Toss with parsley and 2 tablespoons Parmesan, then transfer chicken to a plate.
In the same skillet over low heat, melt the remaining 1 tablespoon butter. Add cream and Velveeta, stirring until smooth.
Stir in mozzarella and remaining 2 tablespoons Parmesan. Add pasta water a little at a time until the sauce coats a spoon smoothly.
Toss spaghetti with the sauce. Serve alongside the chicken and garnish with parsley.

Why This Recipe Works

Bite-size chicken cubes cook quickly and evenly. Cutting the chicken into bite-size pieces means it cooks in just 6–8 minutes and stays juicy. It also gives you more surface area for that golden, garlicky sear. The garlic butter is the star of the show. Butter, olive oil, and fresh garlic come together to create a rich, fragrant coating for the chicken. The parsley and Parmesan finish it off with a fresh, savory note. Cajun seasoning adds a subtle, savory kick. A half-teaspoon brings warmth and depth without overpowering the dish. It complements the garlic butter and creamy sauce beautifully. The three-cheese sauce is rich, creamy, and perfectly balanced. Velveeta melts smoothly and adds creaminess, mozzarella adds stretch and mild flavor, and Parmesan adds salty, nutty depth. Together, they create a sauce that’s silky and flavorful. Reserving pasta water is the secret to a smooth sauce. The starchy water helps the cheese sauce loosen and cling to the spaghetti. Add it a little at a time until the sauce coats the back of a spoon. Cooking the chicken first and the sauce second keeps everything efficient. The same skillet is used for both, so the sauce picks up all the flavorful browned bits left behind by the chicken. Serving the chicken alongside the pasta keeps it crispy. Instead of tossing the chicken into the sauce (which would soften the crust), it’s served alongside the spaghetti so you get the best of both textures.

Pro Tips for Perfect Results Every Time

Cut the chicken into even bite-size pieces. Even pieces cook at the same rate, so every bite is juicy and cooked through. Pat the chicken dry before seasoning. Moisture prevents the chicken from searing. Use paper towels to pat it dry, then season. Season the chicken generously. The salt, pepper, and Cajun seasoning are the only seasoning the chicken gets, so don’t be shy. Heat the oil and butter until shimmering. A hot skillet ensures the chicken browns rather than steams. Let the butter melt and the oil shimmer before adding the chicken. Cook the chicken in a single layer. Crowding the pan steams the chicken instead of searing it. Work in batches if needed. Use a meat thermometer to check doneness. The chicken should reach 165°F (74°C) in the center. This is the most reliable way to know it’s fully cooked. Add the garlic at the end, over lower heat. Garlic burns quickly, so add it during the last 30 seconds of cooking. This keeps it sweet and fragrant rather than bitter. Reserve at least 1 cup of pasta water. You’ll use it to loosen the cheese sauce. If you forget, you can use warm water or broth instead. Melt the Velveeta over low heat. High heat can cause Velveeta to separate or become grainy. Low and slow is the key to a smooth sauce. Add the cheese gradually. Stir in the mozzarella and Parmesan a little at a time, stirring until melted before adding more. This ensures a smooth, creamy sauce. Add pasta water a little at a time. You may not need all of it. Add it slowly, stirring constantly, until the sauce reaches your desired consistency. Toss the spaghetti with the sauce while it’s hot. Hot pasta absorbs the sauce better and helps it cling to every strand. Garnish with fresh parsley for a pop of color. It adds freshness and makes the dish look finished.

Variations and Substitutions

Use a different protein. Shrimp, sausage, or ground beef all work beautifully in place of the chicken. Adjust the cooking time based on the protein. Use a different pasta. Fettuccine, linguine, penne, or rotini all work beautifully in place of the spaghetti. Adjust the cook time to the shape. Make it spicier. Add extra Cajun seasoning, red pepper flakes, or a pinch of cayenne to the chicken. Add vegetables. Sautéed mushrooms, spinach, bell peppers, or broccoli can be added to the sauce or served alongside. Make it a one-pan meal. Toss the chicken into the pasta and sauce just before serving for a one-pan meal. The chicken will soften slightly but the flavor will be incredible. Make it lighter. Use half-and-half instead of heavy cream and reduce the Velveeta to ½ cup. The sauce will be slightly thinner but still delicious. Make it gluten-free. Use gluten-free spaghetti and verify that your seasonings and cheeses are gluten-free. Make it dairy-free. Use dairy-free butter, dairy-free cream, and dairy-free cheese alternatives. Make it a baked pasta dish. Toss the spaghetti, sauce, and chicken together, transfer to a baking dish, top with mozzarella, and broil until bubbly and golden. Add a splash of white wine. A splash of dry white wine added to the skillet after cooking the chicken adds brightness and depth to the sauce.

Storage and Reheating

Refrigerator: Store the chicken and pasta separately in airtight containers for up to 3 days. The sauce will thicken as it chills. Reheating: Reheat the chicken in a 350°F (175°C) oven for 8–10 minutes, or in a skillet over medium heat, until warm and crispy. Reheat the pasta and sauce gently on the stovetop over low heat, adding a splash of cream or pasta water to loosen the sauce. Avoid boiling, which can cause the cheese to separate. Freezer: This dish doesn’t freeze perfectly because the cream and cheese can separate when thawed. It’s best enjoyed fresh. Make ahead: You can cook the chicken and make the sauce up to 2 days in advance and store them separately in the refrigerator. Cook the spaghetti fresh and reheat the sauce gently just before serving. Reheating leftovers: Warm individual portions in the microwave in 1-minute intervals, stirring between each. Add a splash of cream or pasta water if the sauce looks thick. Food safety: Since this dish contains chicken and dairy, don’t leave it at room temperature for more than 2 hours. Refrigerate leftovers promptly.

What to Serve With It

This dish is a complete meal on its own, but a few sides round it out beautifully:

Garlic bread or crusty Italian bread for soaking up the sauce
A crisp Caesar salad or Italian garden salad
Roasted broccoli with garlic and lemon
Sautéed spinach with garlic and olive oil
Bruschetta with fresh tomatoes and basil
A glass of white wine — Chardonnay or Pinot Grigio pair beautifully
