Step‑by‑Step Instructions for Golden Cheese Steak Tortellini Casserole

Step 1: Preheat and Season
Begin by preheating your oven to 375°F (190°C). While it heats, season your sirloin steak generously with salt and black pepper. Make sure to coat both sides evenly for the best flavor. This is an essential step to enhance the taste of your Golden Cheese Steak Tortellini Casserole.

Step 2: Sear the Steak
In a large skillet, heat 2 tablespoons of olive oil over medium-high heat. Once the oil shimmers, add the seasoned steak and sear for 2–3 minutes on each side, until browned and cooked to your preference. The steak should be juicy and slightly caramelized. Remove it from the skillet and set aside to rest while you prepare the sauce.

Step 3: Make the Roux
In the same skillet, lower the heat to medium, and add 3 tablespoons of butter. Allow it to melt completely, then add minced garlic, sautéing for about 30 seconds until fragrant. Stir in ¼ cup of all-purpose flour and cook for 1 minute, stirring constantly to form a roux that will thicken your cheese sauce for the Golden Cheese Steak Tortellini Casserole.

Step 4: Create the Cheese Sauce
Gradually whisk in 2 cups of milk and 1 cup of beef broth, ensuring there are no lumps. Continue to stir regularly, bringing the mixture to a gentle simmer. Once it’s thick and creamy, add 2 cups of shredded cheddar cheese, Dijon mustard, and 1 teaspoon of paprika, stirring until fully melted and smooth. This velvety sauce brings richness to your casserole.

Step 5: Prepare the Tortellini
While the sauce is thickening, cook your cheese tortellini according to the package instructions, but slightly undercook them for just about 1 minute. Drain the tortellini and toss them with a drizzle of olive oil to prevent sticking. This step ensures that your tortellini retains their tender texture in the Golden Cheese Steak Tortellini Casserole.

Step 6: Combine Ingredients
In a greased 9×13 baking dish, combine the cooked tortellini, seared steak cut into bite-sized pieces, and the creamy cheese sauce. Gently mix everything together until well-coated, ensuring that the steak and tortellini are evenly distributed throughout the dish. This step sets the foundation for a delicious casserole.

Step 7: Add the Topping
Sprinkle 1 to 1.5 cups of shredded mozzarella cheese evenly over the top of the casserole. Make sure to cover all areas so every bite has a cheesy topping. This creates a beautiful, golden crust when baked.

Step 8: Bake
Place the baking dish in the preheated oven and bake uncovered for 20–25 minutes, or until the cheese is bubbly and lightly golden. Keep an eye on it, as the golden color is a sure sign that your Golden Cheese Steak Tortellini Casserole is ready to enjoy.

Step 9: Garnish and Serve
Once baked, remove the casserole from the oven and let it rest for about 5 minutes. Sprinkle freshly chopped parsley on top for a pop of color and flavor. Serve warm alongside a fresh salad or some garlic bread for a comforting meal that your family will love!

Expert Tips for Golden Cheese Steak Tortellini Casserole

Mind the Tortellini: Ensure you slightly undercook the tortellini to maintain their texture during baking. This prevents them from becoming mushy in the finished dish.
Smooth Cheese Sauce: For a velvety cheese sauce, warm the milk slightly before mixing it in. Cold milk can create lumps in your Golden Cheese Steak Tortellini Casserole.
Cook in Batches: When searing the steak, avoid overcrowding the skillet. This helps achieve a perfect golden crust instead of steaming the meat.
Finish with a Broil: For an extra crispy topping, broil the casserole for 1–2 minutes at the end of baking. Just keep an eye on it to avoid burning!
Season Generously: Make sure to season each layer—steak, sauce, and tortellini—to elevate the overall flavor of your casserole. Don’t skip the salt and pepper!
