For the Casserole

Sirloin Steak (1 lb) – The protein powerhouse that gives this casserole its rich flavor; swap with chicken or sausage for a twist.
Salt & Black Pepper – Essential seasonings that enhance the steak’s savory taste; consider using sea salt for an elevated touch.
Olive Oil (1 tbsp) – Perfect for searing the steak and locking in juices; a light vegetable oil works too if preferred.
Butter (2 tbsp) – This adds lusciousness to the cheese sauce; stick with unsalted butter to control your casserole’s saltiness.
Garlic (3 cloves, minced) – Provides a fragrant, aromatic punch to the sauce; fresh garlic gives the best flavor!
All-Purpose Flour (1 tbsp) – Key for thickening the cheese sauce; try gluten-free flour for a suitable alternative.
Milk (2 cups, whole or 2%) – The creamy base for the sauce; almond or oat milk can work as dairy-free options, just be mindful of flavor differences.
Beef Broth (1 cup) – Adds depth and richness to your sauce; vegetable broth is great for a lighter option.
Sharp Cheddar Cheese (2 cups, shredded) – Provides the bold flavor and creaminess that makes this casserole shine; switch it up with Gruyère or Fontina if you’re feeling adventurous.
Dijon Mustard (1 tsp optional) – A hint of complexity in the sauce; feel free to leave it out if mustard’s not your thing.
Paprika (1 tsp) – Adds warmth and a touch of color; smoked paprika can really elevate the flavor profile.
Cheese Tortellini (1 package, 20 oz) – This delightful pasta absorbs all the delicious sauce flavors; using frozen tortellini is an excellent choice—just be sure to undercook slightly before baking.

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

Step 1: Preheat and Prep
Begin by preheating your oven to 375°F (190°C). While it’s warming up, take your sirloin steak and season it generously with salt and black pepper. This will enhance the savory flavors in your Golden Cheese Steak Tortellini Casserole. Have a large skillet ready on medium-high heat with olive oil, as you’ll soon sear the steak to perfection.

Step 2: Sear the Steak
Once the skillet is hot, add the steak pieces and sear them for about 2-3 minutes on each side until they’re beautifully browned. This quick yet crucial step locks in the juices and flavor. Once seared, remove the steak from the skillet and set it aside on a plate to rest while you prepare the creamy sauce.

Step 3: Create the Roux
In the same skillet, add butter and allow it to melt over medium heat. Once the butter is melted, add the minced garlic and cook for about 30 seconds until fragrant. Next, sprinkle in the flour, stirring constantly for about a minute, forming a roux that will thicken your cheese sauce to creamy goodness in the Golden Cheese Steak Tortellini Casserole.

Step 4: Whisk in the Liquids
Gradually whisk in the milk and beef broth, stirring continuously until the mixture is smooth and comes to a gentle simmer. This should take about 2-3 minutes. Once it’s thickened slightly, stir in the shredded cheddar cheese, Dijon mustard (if using), and paprika, allowing everything to melt into a rich and creamy sauce that envelops the tortellini beautifully.

Step 5: Cook the Tortellini
Prepare the cheese tortellini according to the package instructions but cook it slightly underdone—about 1-2 minutes less than suggested. This ensures it maintains its texture during baking. Once ready, drain the tortellini and toss it with a little olive oil to prevent sticking before combining it with the cooked steak and cheesy sauce.

Step 6: Combine in Baking Dish
In a greased 9×13 baking dish, combine the undercooked tortellini, seared steak, and creamy cheese sauce. Gently stir everything together until well mixed, ensuring that every bite of your Golden Cheese Steak Tortellini Casserole is coated in that luscious sauce.

Step 7: Bake to Perfection
Sprinkle the shredded mozzarella cheese evenly on top of the casserole, creating a tempting layer of cheesy goodness. Place the baking dish in the preheated oven and bake uncovered for 20-25 minutes. You’ll know it’s done when the cheese is bubbly and golden brown, creating a delightful crust.

Step 8: Garnish and Serve
After baking, remove the casserole from the oven and allow it to rest for about 5 minutes. This resting time helps the flavors settle and makes serving easier. Finally, garnish your Golden Cheese Steak Tortellini Casserole with fresh chopped parsley before serving to add a burst of color and freshness.

Expert Tips for Golden Cheese Steak Tortellini Casserole

Maintain Steak Juiciness: Avoid overcrowding the pan when searing steak. This ensures each piece caramelizes nicely, enhancing flavor.
Perfect Tortellini Texture: Slightly undercook the tortellini according to the package instructions. This prevents them from becoming mushy during baking in the casserole.
Use Fresh Cheese: Opt for freshly grated cheddar and mozzarella. It melts better than pre-shredded versions, leading to a creamier sauce in your casserole.
Rest Before Serving: Allow the casserole to rest for 5 minutes after baking. This enhances the stability of your slices and makes serving easier.
Add a Crispy Top: For a visually appealing finish, broil the casserole for the last 1-2 minutes of baking. Crispy cheese adds extra flavor and texture to the dish.

Golden Cheese Steak Tortellini Casserole Recipe FAQs

How do I choose the best sirloin steak?
Absolutely! Look for sirloin steak that is bright red with minimal dark spots. The cuts should have some marbling (fat running through the meat), which ensures flavor and tenderness. When selecting, avoid any that have a dull color or are overly aged.

What are the best storage methods for leftovers?
You can store your leftover Golden Cheese Steak Tortellini Casserole in an airtight container in the fridge for up to 3 days. Just reheat it in the microwave or bake at 350°F (175°C) until warmed through. It’s always best to cover it while reheating to keep it moist.

Can I freeze this casserole?
Very! The casserole can be frozen before baking for up to 3 months. To do this, prepare the entire dish and cover it tightly with foil or plastic wrap to prevent freezer burn. When you’re ready to bake, simply thaw it overnight in the refrigerator and add around 10-15 minutes to the baking time to ensure it cooks through.

What should I do if the casserole is too dry after baking?
If your casserole comes out dry, there are a couple of tricks you can employ. First, ensure you have enough cheese sauce mixed in—add a bit more milk or broth to the sauce next time. If it’s already baked, mix a bit of warm milk or broth into individual servings, or serve with a side of warm cheese sauce for dipping!

Are there any dietary considerations I should keep in mind?
For those with dietary restrictions, you can easily make the Golden Cheese Steak Tortellini Casserole gluten-free by swapping regular flour with a gluten-free alternative. To accommodate lactose intolerance, opt for lactose-free milk and cheese. Also, ensure to check the tortellini packaging for any allergens as some brands may contain gluten, dairy, or eggs.

Can I use a different protein in place of the steak?
Yes, you can certainly switch out the steak with chicken, ground beef, or even sausage! If using chicken, I recommend sauting it thoroughly to ensure it’s fully cooked through. For ground beef, brown it in the skillet and then crumble it into the casserole mixture. It’s all about personal preference and making it your own!
