Make Creamy Mushroom Chicken Alfredo Bake: A Simple Method

Step 1: Cook the Pasta

Bring a large pot of salted water to a boil. Add the fettuccine pasta and cook according to package instructions until al dente. Drain the pasta and set it aside while you prepare the sauce and chicken.

Step 2: Sauté Chicken and Mushrooms

In a large skillet, heat 1 tablespoon of olive oil over medium-high heat. Add the diced chicken breasts, season with salt, pepper, and Italian seasoning, and cook until the chicken is no longer pink and starts to brown, about 5-7 minutes. Remove the chicken from the skillet and set aside.

In the same skillet, add the sliced mushrooms and minced garlic. Sauté until the mushrooms are golden and tender, about 5 minutes. The garlic will become fragrant and add a wonderful aroma.

Step 3: Prepare the Alfredo Sauce

Reduce the heat to medium and pour in the heavy cream and chicken broth. Stir well, scraping up any browned bits from the bottom of the skillet for extra flavor. Let the mixture simmer for 3-4 minutes until it begins to thicken slightly.

Stir in the grated Parmesan cheese until the sauce is smooth and creamy. Season with additional salt and pepper to taste.

Step 4: Combine Pasta, Chicken, and Sauce

Return the cooked chicken to the skillet with the mushroom Alfredo sauce. Add the drained fettuccine pasta and gently toss everything together until the noodles are thoroughly coated with the creamy sauce and the chicken and mushrooms are evenly distributed.

Step 5: Assemble and Bake

Preheat your oven to 375°F (190°C). Pour the pasta mixture into a greased 9×13 inch baking dish. Sprinkle the shredded mozzarella cheese evenly over the top for that irresistible cheesy crust.

Bake uncovered for 20-25 minutes, or until the cheese is melted, bubbly, and golden brown on top.

Step 6: Garnish and Serve

Remove from the oven and let it rest for a few minutes before serving. Garnish with freshly chopped parsley for a pop of color and fresh flavor. Grab a fork and enjoy the ultimate creamy comfort food!

Make It Fit Your Plan

• For a lighter version, swap heavy cream with half-and-half and reduce the cheese slightly.
• Add spinach or kale for a boost of greens and nutrients.
• Use gluten-free pasta to accommodate dietary needs without sacrificing taste.
• Substitute mushrooms with sun-dried tomatoes or roasted red peppers for a different flavor twist.
• Try swapping mozzarella with provolone or fontina for a unique cheesy experience.

Pitfalls & How to Prevent Them

• Overcooked pasta: Cook the fettuccine al dente since it will bake further in the oven. Overcooked pasta becomes mushy.
• Watery sauce: Be sure to let the cream and broth simmer enough to thicken before adding cheese. Also, don’t add too much broth.
• Undercooked chicken: Dice chicken into even pieces and cook fully before baking to ensure it’s safe and juicy.
• Bland flavor: Don’t skip seasoning with salt, pepper, and Italian seasoning. Fresh garlic is key to elevating the aroma and taste.

Refrigerate, Freeze, Reheat

This Creamy Mushroom Chicken Alfredo Bake is fantastic for leftovers and meal prep. Store any leftovers in an airtight container in the refrigerator for up to 3 days.

For freezing, portion the bake into freezer-safe containers and freeze for up to 2 months. Thaw overnight in the refrigerator before reheating.

To reheat, cover with foil and warm in a 350°F (175°C) oven for 15-20 minutes or until heated through. Alternatively, microwave individual portions on medium power, stirring occasionally to ensure even heating.

Helpful Q&A

Can I use chicken thighs instead of breasts?

Absolutely! Boneless, skinless chicken thighs will add a bit more richness and tenderness to this bake. Just dice them similarly and cook until fully done before combining with the sauce.

What type of mushrooms work best?

Cremini or white button mushrooms are great choices because they’re mild and absorb flavors well. You can also experiment with shiitake or portobello for a more intense mushroom flavor.

How do I make this dish dairy-free?

Use a dairy-free cream alternative like coconut cream and substitute Parmesan and mozzarella with vegan cheese options. The texture and flavor will differ slightly, but the dish will remain creamy and delicious.

Can I make this ahead of time?

Yes! You can assemble the bake completely, cover it tightly, and refrigerate for up to 24 hours before baking. Just add a few extra minutes to the baking time if baking straight from the fridge.
