Step-by-Step Instructions

Creating the perfect Golden Cheese Steak Tortellini Casserole is easier than you might think, especially when you follow these detailed steps. From searing the steak to baking a bubbly, golden casserole, each stage is designed to maximize flavor and texture. Here’s how to do it:

---

1. Cook the Steak

Begin by preheating your oven to 375°F (190°C). This ensures that the casserole will bake evenly once assembled. While the oven warms, it’s time to prepare your steak. Generously season the bite-sized steak pieces with salt and black pepper. Seasoning at this stage is crucial as it enhances the natural flavors of the meat and ensures every bite is savory and well-balanced.

Next, heat 1 tablespoon of olive oil in a large skillet over medium-high heat. Once the oil shimmers, carefully add the steak pieces in a single layer. Sear each side for about 2–3 minutes until a golden-brown crust forms. This quick sear locks in the juices, giving the steak a tender and flavorful interior. Be mindful not to overcrowd the pan—if the pieces are too close together, they will steam instead of sear. Cooking in batches may take a few extra minutes but results in perfectly caramelized steak every time.

Once the steak is browned, remove it from the skillet and set it aside. Don’t worry about cooking it fully; it will continue cooking later in the oven, absorbing the flavors of the cheese sauce.

Pro Tip: Searing at too high a heat can burn the outside while leaving the inside undercooked. Medium-high heat is ideal for a perfect balance of crust and tenderness.

2. Make the Golden Cheese Sauce

Using the same skillet keeps the delicious browned bits from the steak, which adds depth to your sauce. Melt 2 tablespoons of butter over medium heat, then add 3 cloves of minced garlic. Cook for about 30 seconds, just until the garlic releases its aroma. Garlic enhances the savory base of the sauce without overpowering the cheese.

Next, stir in 1 tablespoon of flour to create a roux, cooking for approximately one minute. The roux acts as a thickening agent, giving your sauce a rich, velvety texture. Slowly whisk in 2 cups of milk and 1 cup of beef broth, a little at a time, ensuring the mixture is smooth and lump-free.

Now comes the indulgent part: add 2 cups of shredded cheddar cheese, 1 teaspoon of Dijon mustard (optional but recommended for depth), and 1 teaspoon of paprika. Stir until the sauce is creamy and silky. The combination of cheeses, mustard, and spices creates a luxurious, golden sauce that perfectly complements the steak and pasta.

Tip: For an ultra-smooth sauce, warm your milk slightly before whisking. This prevents lumps and ensures a creamy consistency.

3. Prepare the Tortellini

Cook 1 package (20 oz) of cheese tortellini according to package instructions. Be careful not to overcook them; slightly undercooked tortellini will hold their shape and texture after baking. Once drained, toss them gently with a small drizzle of olive oil to prevent sticking.

Combining the pasta with the golden cheese sauce and seared steak ensures that every bite is decadent and well-coated. The tortellini acts as a soft, pillowy base that absorbs the rich flavors of the sauce while adding satisfying texture.

---

4. Assemble the Casserole

Grease a 9×13-inch baking dish to prevent sticking. Layer the prepared tortellini, steak, and cheese sauce evenly, making sure every bite will have a mix of pasta, meat, and creamy sauce. Stir gently to combine without breaking up the tortellini. Sprinkle ½ cup of shredded mozzarella over the top. This layer will melt during baking, creating a golden, bubbly finish that makes the casserole visually irresistible.

Even though the assembly is quick, the aroma of the combined ingredients already gives a sense of indulgence. This step is where the dish transforms from a simple skillet meal to a hearty, comforting casserole.

---

5. Bake to Perfection

Place the assembled casserole in the preheated oven and bake uncovered for 20–25 minutes, or until the cheese is bubbly and lightly golden. Keep an eye on the top to avoid over-browning. Once done, remove from the oven and garnish with 2 tablespoons of chopped parsley for a fresh pop of color and flavor.

Allow the casserole to rest for 5 minutes before serving. This short resting time allows the cheese sauce to thicken slightly, making it easier to cut and serve. It also gives the flavors a chance to meld, ensuring every bite is rich, cheesy, and perfectly seasoned.

Pro Tip: For extra presentation appeal, you can broil the casserole for the last 1–2 minutes to achieve a slightly crisp, golden top.

Tips for the Best Golden Cheese Steak Tortellini Casserole

1. Don’t overcook the tortellini: Slightly undercooking ensures they remain tender and perfectly textured after baking.

2. Use fresh cheese: Pre-shredded cheese often contains anti-caking agents that can affect melt quality.

3. Season generously: Don’t skimp on salt and pepper—seasoning each component properly enhances the overall flavor.

4. Make ahead: Prepare the casserole up to the assembly step, cover, and refrigerate for up to 24 hours. Bake when ready to serve.

Frequently Asked Questions

1. Can I use frozen tortellini?

Yes! Frozen tortellini is a convenient option and works perfectly in this casserole. The key is to slightly undercook the tortellini according to package instructions before baking. This ensures the pasta retains its shape and texture after baking, absorbing just the right amount of the golden cheese sauce. Avoid overcooking, as the tortellini will continue to cook in the oven along with the steak and cheese sauce. For best results, gently toss the drained tortellini with a drizzle of olive oil to prevent sticking before combining it with the steak and sauce.

---

2. Can I make this casserole ahead of time?

Absolutely! This casserole is an excellent choice for meal prep or entertaining. You can assemble the entire dish up to 24 hours in advance. Cover the baking dish tightly with foil or plastic wrap and refrigerate. When ready to bake, simply remove from the fridge, let it sit at room temperature for a few minutes, and bake according to the recipe instructions. You may need to add a few extra minutes to the baking time since a chilled casserole takes longer to reach the perfect bubbly and golden consistency. Preparing it ahead not only saves time but also allows the flavors to meld, enhancing the overall taste.

---

3. Can I freeze this casserole?

Yes, freezing is a great option if you want to make this casserole in bulk or store leftovers for later. Assemble the casserole without baking, cover it tightly with aluminum foil, and freeze for up to three months. When ready to enjoy, thaw overnight in the refrigerator. Once thawed, bake as directed, adding extra minutes as needed to ensure the casserole is heated through and the cheese is bubbling. Freezing does not compromise the flavor or texture, making this dish a convenient, make-ahead comfort meal.

---

4. Can I use a different type of cheese?

Definitely! While sharp cheddar gives the casserole its classic, rich flavor, this recipe is very versatile. You can experiment with other cheeses like Gruyère, Fontina, or mild Swiss cheese for a slightly different taste profile. Mixing cheeses can also add complexity and depth—try combining cheddar with mozzarella for extra meltiness or adding a bit of Parmesan for a savory punch. The key is to choose cheeses that melt well and complement the creamy sauce without overpowering the steak.
