Ingredients You’ll Need

This Golden Cheese Steak Tortellini Casserole Recipe shines because of its simple yet carefully chosen ingredients that balance taste, texture, and color. Each item plays a crucial role, from the juicy sirloin cubes to the melty cheddar that makes this casserole an instant favorite.

• Sirloin steak (1 lb): Bite-sized pieces ensure tender, juicy meat that holds up beautifully in the casserole.
• Salt & black pepper: Essential for seasoning the steak and bringing out depth in every flavor.
• Olive oil (1 tbsp): Used to sear steak and keep the tortellini from sticking, adding a subtle richness.
• Butter (2 tbsp): Creates a luscious base for the creamy cheese sauce.
• Garlic (3 cloves, minced): Adds a fragrant, savory punch that enhances the whole dish.
• All-purpose flour (1 tbsp): Thickens the sauce to the perfect consistency without clumps.
• Milk (2 cups): Whole or 2% milk keeps the sauce creamy and comforting.
• Beef broth (1 cup): Adds savory umami that complements the steak perfectly.
• Sharp cheddar cheese (2 cups): The star ingredient that melts into a smooth, flavorful sauce.
• Dijon mustard (1 tsp, optional): A subtle tang that lifts the cheese sauce.
• Paprika (1 tsp): Gives a hint of warmth and a beautiful golden color.
• Cheese tortellini (20 oz): Fresh or refrigerated, slightly undercooked for the best texture after baking.
• Mozzarella cheese (½ cup, shredded): For that irresistible bubbly, golden top layer.
• Chopped parsley (2 tbsp): A fresh garnish that brightens every serving.

How to Make Golden Cheese Steak Tortellini Casserole Recipe

Step 1: Sear the Steak

Start by seasoning your bite-sized sirloin steak pieces with salt and black pepper. Heat olive oil in a skillet over medium-high heat until shimmering, then add the steak. Sear each side for 2 to 3 minutes until you get a beautiful golden crust. This step locks in the juices and flavor that will shine throughout the casserole. Once browned, set the steak aside—this is going to make your dish seriously tasty.

Step 2: Prepare the Cheese Sauce

In the same skillet, melt butter over medium heat to capture all those steak bits left behind. Add minced garlic and cook for about 30 seconds until fragrant—this little addition intensifies the flavor beautifully. Sprinkle in the flour and stir constantly for a minute to form a roux, which thickens your sauce perfectly. Gradually whisk in milk and beef broth, stirring until smooth. Now stir in your shredded sharp cheddar, Dijon mustard for a subtle kick, and paprika for color and mild warmth. Cook gently until the sauce is creamy and luscious—this is what makes the casserole rich and comforting.

Step 3: Cook the Tortellini

Boil the cheese tortellini according to the package instructions, but here’s a pro tip: cook them just under al dente because they’ll continue cooking in the oven. Drain the tortellini and toss lightly with olive oil to prevent sticking—this keeps the pasta tender and delightful in the final casserole.

Step 4: Assemble and Bake

Grease a 9×13-inch baking dish to ensure nothing sticks. Combine the tortellini, seared steak, and cheesy sauce right in the dish and stir gently so everything is evenly coated without smashing the pasta. Sprinkle the shredded mozzarella evenly over the top for that golden, bubbly crust that makes this casserole so irresistible. Bake uncovered at 375°F (190°C) for about 20 to 25 minutes until the cheese is perfectly bubbly and golden brown. Let it rest a few minutes to settle the flavors before digging in.

Garnishes

Finishing with a sprinkle of fresh chopped parsley adds a lovely pop of color and a hint of freshness that balances the richness of the dish. It’s simple but makes the presentation beautiful and inviting, perfect for family dinners or casual entertaining.

Side Dishes

This flavorful casserole pairs wonderfully with crisp green salads, garlic bread for mopping up every last bit of cheesy goodness, or even roasted vegetables like asparagus or broccoli. These sides add fresh textures and lighten up the meal without taking away attention from the star of the show.

Creative Ways to Present

Serve this Golden Cheese Steak Tortellini Casserole Recipe straight from the baking dish for a cozy, rustic vibe, or portion it onto warm plates and garnish each with extra parsley and a drizzle of olive oil for a more polished look. You can even add a dash of crushed red pepper flakes for those who enjoy a little heat. It’s a dish as versatile as it is delicious.

Make Ahead and Storage

Storing Leftovers

Leftover casserole keeps beautifully in an airtight container in the refrigerator for up to three days. The flavors meld even more overnight, making it an excellent choice for quick weekday lunches or dinners.

Freezing

You can freeze the entire assembled casserole before baking. Wrap it tightly with plastic wrap and foil, then store in the freezer for up to two months. When ready, thaw overnight in the fridge and bake as usual, adding a few extra minutes to the cooking time if needed.

Reheating

Reheat individual portions in the microwave until warm throughout, or place leftovers in a preheated oven at 350°F (175°C) covered with foil to prevent drying out. This keeps the cheese creamy and the steak tender without drying the pasta.

FAQs

Can I use frozen tortellini for this casserole?

Absolutely! Just be sure to cook the frozen tortellini according to the package instructions and slightly undercook them so they don’t become mushy during baking.

What type of cheese works best in this recipe?

Sharp cheddar is ideal for its strong flavor and good melting qualities, but you can also mix in a golden cheddar blend for extra richness. Mozzarella on top gives you that classic golden, bubbly finish.

Can I substitute the sirloin steak with another protein?

Yes! Tender steak tips work wonderfully, and you could also try thinly sliced ribeye or even chicken if you want a lighter twist, but the beef flavors are what make this casserole so special.

Is Dijon mustard necessary in the cheese sauce?

It’s optional but highly recommended. Dijon adds a subtle tanginess that cuts through the richness of the cheese, enhancing the overall flavor without overpowering it.

How do I prevent the casserole from getting mushy?

The key is to slightly undercook the tortellini and avoid overbaking the casserole. Also, letting it rest after baking helps the sauce thicken up a bit so each bite holds together beautifully.
