Ingredients
The foundation of this bake rests on a few star players: succulent chicken breasts, earthy mushrooms, and sturdy pasta that holds sauce well. A rich cream base, infused with garlic and thyme, ties everything together, while a generous blend of mozzarella and parmesan creates that irresistible golden crust. Fresh herbs finish the dish with a burst of brightness.
Main Ingredients
- 12 oz (340 g) penne pasta
- 2 large boneless, skinless chicken breasts, cut into bite‑size cubes
- 8 oz (225 g) cremini mushrooms, sliced
Sauce Components
- 1 cup heavy cream
- ½ cup chicken broth
- 2 cloves garlic, minced
- 1 teaspoon dried thyme
Cheese & Seasonings
- 1 cup shredded mozzarella
- ½ cup grated parmesan
- Salt and freshly ground black pepper, to taste
- 2 tablespoons olive oil
- Fresh parsley, chopped (for garnish)
Together these ingredients create a harmonious balance of texture and flavor. The chicken stays juicy thanks to a quick sear, while the mushrooms add earthiness that deepens the sauce. Cream and broth give the sauce body without becoming heavy, and the cheese blend provides a luscious melt and a crisp, golden finish. A dash of thyme and fresh parsley brighten the entire dish.
Step-by-Step Instructions
Preparing the Base
Begin by bringing a large pot of salted water to a boil. Cook the penne until it’s just al dente—about 2 minutes less than the package directs—so it finishes cooking evenly in the oven. While the pasta cooks, toss the chicken cubes with a pinch of salt, pepper, and one tablespoon of olive oil.
Cooking the Chicken & Mushrooms
- Heat the Pan. Warm a large skillet over medium‑high heat for 2 minutes, then add the remaining olive oil. The oil should shimmer, signaling it’s hot enough to sear without steaming.
- Sear the Chicken. Add the seasoned chicken in a single layer. Let it brown undisturbed for 3‑4 minutes, then flip and cook another 3 minutes. The goal is a golden crust, not full doneness.
- Add Mushrooms & Garlic. Reduce heat to medium, stir in the sliced mushrooms, and sauté until they release their moisture and start to brown, about 4 minutes. Toss in the minced garlic and thyme, cooking for just 30 seconds until fragrant.
- Make the Cream Sauce. Pour the chicken broth into the pan, scraping up any browned bits. Stir in the heavy cream, bring to a gentle simmer, and let it thicken for 3 minutes. Season with additional salt and pepper as needed.
- Combine Everything. Drain the pasta and add it to the skillet, tossing to coat evenly. Transfer the mixture to a greased 9‑x‑13‑inch baking dish, spreading it into an even layer.
Baking & Finishing
Sprinkle the mozzarella and parmesan evenly over the top. Bake in a pre‑heated 375°F (190°C) oven for 20‑25 minutes, or until the cheese is bubbling and a deep golden brown forms. Let the casserole rest for 5 minutes before scattering chopped parsley and serving.
Tips & Tricks
Perfecting the Recipe
Dry the Chicken. Pat the chicken pieces with paper towels before seasoning; excess moisture prevents a proper sear.
Use a Heavy‑Bottomed Skillet. Even heat distribution gives a uniform crust on both chicken and mushrooms.
Don’t Over‑Cook Pasta. Al‑dente pasta absorbs the sauce during baking without turning mushy.
Flavor Enhancements
Finish the sauce with a splash of dry white wine for acidity, or stir in a tablespoon of Dijon mustard for a subtle tang. A pinch of smoked paprika adds depth without overwhelming the creamy base.
Common Mistakes to Avoid
Skipping the resting period after baking lets steam escape, making the top dry. Also, avoid using low‑fat cheese; it won’t melt as smoothly and can result in a grainy texture.
Pro Tips
Grate Cheese Fresh. Freshly grated parmesan releases more flavor than pre‑shredded varieties.
Broil for Extra Crunch. Switch the oven to broil for the last 2 minutes to achieve an ultra‑crisp cheese crust.
Season in Layers. Salt the pasta water, the chicken, and the sauce separately for maximum depth.
Variations
Ingredient Swaps
Replace chicken with turkey cutlets or diced pork tenderloin for a different protein profile. Swap cremini mushrooms for baby bella or shiitake for a richer umami punch. Use whole‑wheat or gluten‑free pasta to match dietary preferences while keeping the same texture.
Dietary Adjustments
For a dairy‑free version, substitute the cream with coconut milk and use a vegan mozzarella blend. To keep it low‑carb, swap the pasta for spiralized zucchini or shirataki noodles. Gluten‑free diners can safely enjoy the dish by choosing certified gluten‑free pasta and broth.
Serving Suggestions
Pair the bake with a simple arugula salad dressed in lemon vinaigrette, or serve alongside buttery garlic bread to mop up extra sauce. For a complete comfort meal, add roasted Brussels sprouts or a crisp Caesar salad.
Storage Info
Leftover Storage
Allow the casserole to cool to room temperature, then transfer portions to airtight containers. Refrigerate for up to four days. For longer keeping, label and freeze in freezer‑safe containers for three months; a layer of foil over the top helps prevent freezer burn.
Reheating Instructions
Reheat in a 350°F (175°C) oven, covered with foil, for 15‑20 minutes until warmed through. Uncover for the final 5 minutes to restore the cheese crust. In a microwave, add a splash of broth, cover, and heat on medium for 2‑3 minutes, stirring halfway.
