One‑Pan Chicken Tetrazzini Casserole with Parmesan – Ready in 45 Minutes

When dinner time feels like a race against the clock, the One‑Pan Chicken Tetrazzini Casserole steps in as a culinary hero. This dish blends the creamy, indulgent flavors of classic tetrazzini with the comforting heartiness of a baked casserole, all while keeping cleanup to a single pan. Imagine tender chicken, al dente pasta, a rich mushroom‑cream sauce, and a golden crust of Parmesan that snaps with every bite. In just 45 minutes—from prep to plate—you’ll have a restaurant‑quality dinner that satisfies both kids and adults alike.

The secret to this recipe’s speed lies in the strategic layering of ingredients and the use of pre‑cooked chicken, which reduces cooking time without sacrificing flavor.

Whether you’re feeding a busy family, entertaining friends, or simply craving a comforting bowl of pasta, this tetrahedron‑shaped masterpiece hits every mark.

Beyond its convenience, this casserole is a nutritional powerhouse. Lean protein from chicken, fiber‑rich whole‑grain pasta, and antioxidant‑laden mushrooms create a balanced meal that supports muscle recovery and overall well‑being. And because it’s baked in one pan, you retain more of the natural juices and flavors, resulting in a dish that’s moist, aromatic, and irresistibly cheesy. Ready to transform your dinner routine?

Ingredients

• 2 cups cooked chicken, shredded or diced (about 2 large breasts)
• 8 oz wide egg noodles or whole‑grain pasta
• 1 ½ cups sliced cremini or button mushrooms
• 1 cup frozen peas (optional for color)
• 3 Tbsp unsalted butter
• 3 Tbsp all‑purpose flour
• 2 cups low‑sodium chicken broth
• 1 cup heavy cream (or half‑and‑half for lighter version)
• ½ cup grated Parmesan cheese, plus extra for topping
• 1 tsp dried thyme
• ½ tsp smoked paprika
• Salt & freshly ground black pepper to taste
• 2 Tbsp fresh parsley, chopped (for garnish)

Step‑by‑Step Instructions

1. Preheat & Prepare: Preheat your oven to 400°F (200°C). Bring a large pot of salted water to a boil, add the pasta, and cook 2 minutes less than package directions (it will finish in the oven). Drain and set aside.
2. Sauté Aromatics: In a 12‑inch skillet or shallow oven‑safe pan, melt butter over medium heat. Add sliced mushrooms and sauté until they release moisture and turn golden, about 4‑5 minutes.
3. Build the Roux: Sprinkle flour over the mushrooms, stirring constantly for 1 minute to form a smooth paste. This eliminates raw flour taste and thickens the sauce later.
4. Deglaze & Simmer: Slowly whisk in chicken broth, ensuring no lumps form. Bring to a gentle boil, then reduce heat and stir in the heavy cream. Simmer 3‑4 minutes until the sauce thickens and coats the back of a spoon.
5. Season: Stir in thyme, smoked paprika, ½ cup Parmesan, salt, and pepper. Taste and adjust seasoning—remember the Parmesan adds saltiness.
6. Combine Main Ingredients: Add the cooked chicken, partially cooked pasta, and peas (if using) to the sauce. Toss gently to coat everything evenly.
7. Transfer to Oven: Sprinkle an additional ¼ cup Parmesan over the top for a crisp crust. Place the pan in the pre‑heated oven and bake 12‑15 minutes, or until the cheese is bubbling and golden brown.
8. Rest & Garnish: Remove from oven, let stand 5 minutes. Sprinkle fresh parsley for color and a burst of freshness before serving.
9. Serve: Scoop generous portions onto plates, pairing with a simple green salad or steamed asparagus for a complete meal.
10. Enjoy: Relish the creamy, cheesy goodness knowing you’ve delivered a wholesome dinner in under an hour.
