Instructions For Baked Chicken Alfredo spaghetti

Follow these clear, step-by-step instructions to create a delicious baked chicken alfredo spaghetti that’s sure to impress. This recipe makes weeknight cooking simple and enjoyable.
- Preheat and Prep Chicken: Preheat your oven to 375°F (190°C). Drizzle 1 tbsp of olive oil over the boneless, skinless chicken breast. Season each side of the chicken evenly with the Mrs. Dash seasoning and the southwest seasoning blend.
- Bake Chicken: Place the seasoned chicken in a baking dish. Cover the dish with foil and bake for 30 minutes, or until the chicken is cooked through and reaches an internal temperature of 165°F (74°C). Remove from oven and let it rest briefly.
- Boil Pasta: While the chicken bakes, bring a large pot of salted water to a rolling boil. Add the 16 ounces of spaghetti and cook according to package directions until al dente. This ensures your pasta holds up well during baking.
- Drain and Dress Pasta: Once cooked, drain the spaghetti thoroughly. Return the hot pasta to the large pot or transfer it to your 9×13 inch baking dish. Drizzle 2 tbsp of olive oil over the pasta and toss to prevent sticking.
- Dice Chicken and Combine: Cut the cooked chicken into bite-sized pieces. Add the diced chicken to the pasta in the baking dish, along with the drained canned tomatoes.
- Add Alfredo Sauce and Initial Cheese: Pour 1 1/2 jars of the alfredo sauce over the pasta mixture. Gently fold it in using tongs or a large spoon until everything is well coated.
- Season the Mixture: Season the pasta mixture generously with the garlic powder, seasoning salt, and ground black pepper. Stir again to distribute the flavors evenly.
- Fold in Green Onions and Cheese: Sprinkle in 1/2 cup of the sharp cheddar cheese and 1/4 cup of the chopped green onions over the pasta. Use tongs or another kitchen utensil to carefully fold everything in, ensuring the cheese and onions are well distributed.
- Top with Italian Cheese: Sprinkle the remaining 1 cup of Italian blend cheese evenly over the top of the pasta mixture in the baking dish. This will create a beautiful golden crust.
- Final Bake: Place the baking dish back into the preheated oven. Bake for 25 minutes at 375°F (190°C), or until the cheese is bubbly and golden brown.
- Warm Extra Sauce (Optional): While the dish bakes, you can gently heat the remaining 1/2 jar of alfredo sauce on the stovetop or in the microwave. Keep it warm for anyone who prefers extra sauce with their serving.
- Serve Hot: Remove the baked chicken alfredo spaghetti from the oven. Let it rest for a few minutes before serving directly from the dish. Enjoy this comforting and creamy meal!
Pro Tips for Perfect Chicken Alfredo Spaghetti
Making great chicken alfredo spaghetti is easier than you think with these simple tips. Follow these suggestions to achieve the best results every time.
- Don’t Overcook Pasta: Cook spaghetti just until al dente; it will soften more in the oven. This prevents mushy pasta.
- Achieve Juicy Chicken: Let the chicken rest for a few minutes after baking before dicing. This keeps the chicken tender and moist.
- Enhance Flavor: For an extra flavor boost, sauté a clove or two of minced fresh garlic with a splash of olive oil before adding it to your sauce.
- Prevent Sauce from Breaking: If using homemade sauce, avoid overheating it. Jarred sauces are generally more stable.
- Ensure Smooth Cheese Melt: Use freshly grated cheese if possible; it melts smoother than pre-shredded varieties, which often contain anti-caking agents.
- Adjust Seasoning: Always taste the pasta mixture before baking and adjust salt and pepper as needed.
Serving Suggestions, Storage, & Variations
This baked chicken alfredo spaghetti is a versatile dish, perfect for customizing. Here’s how to serve it best and manage leftovers.
Serving Suggestions
- Garlic Bread: A classic pairing, warm garlic bread or cheesy garlic knots are perfect for soaking up the creamy sauce.
- Fresh Salad: A light, crisp green salad with a vinaigrette dressing cuts through the richness of the pasta.
- Roasted Vegetables: Sides like roasted broccoli, asparagus, or green beans add a healthy, colorful complement.
Storage
- Store Leftovers: Transfer any remaining chicken alfredo spaghetti to an airtight container. It will keep fresh in the refrigerator for up to 3-4 days.
- Reheat Gently: Reheat individual portions in the microwave or a covered skillet over low heat.
- Add Moisture: A splash of milk or chicken broth can help loosen the sauce and restore creaminess when reheating.
Variations
- Add Extra Vegetables: Stir in steamed broccoli florets, fresh spinach, or sautéed mushrooms for added nutrients and flavor.
- Different Proteins: Swap the chicken for cooked shrimp, crumbled Italian sausage, or even plant-based protein alternatives.
- Make it Spicy: A pinch of red pepper flakes mixed into the sauce or sprinkled on top adds a delightful kick.
- Different Pasta Shapes: Experiment with penne, rigatoni, or even rotini for a fun change of texture.
