What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture. Here’s what you’ll need:

• Cheese tortellini: Fresh or frozen works perfectly—choose your favorite brand.
• Steak: Thinly sliced flank steak or sirloin for tender bites (you can also use leftover steak).
• Bell peppers: One red and one green, sliced thin for vibrant color and flavor.
• Onions: A medium yellow onion, thinly sliced for sweetness.
• Garlic: Fresh minced garlic for depth of flavor.
• Shredded cheese: Provolone or mozzarella for gooey, melty goodness.
• Heavy cream: Adds richness to the sauce.
• Beef broth: Enhances the savory steak flavor.
• Olive oil: For sautéing the veggies and steak.
• Salt & pepper: To taste, for seasoning.
• Optional: Worcestershire sauce (adds a tangy depth to the steak and sauce).

Feel free to swap out the steak for ground beef, chicken, or even mushrooms if you’re looking for a vegetarian option. The cheese can also be adjusted—cheddar, gouda, or even a blend of cheeses work beautifully.

Equipment Needed

• Large skillet: For sautéing the steak and veggies.
• Pot: To boil the tortellini.
• Casserole dish: A 9×13-inch dish is ideal for baking.
• Knife: A sharp knife for slicing steak, peppers, and onions.
• Cutting board: For prepping your ingredients.
• Mixing spoon: For stirring everything together.

If you don’t have a casserole dish, you can use a deep oven-safe skillet. Also, nonstick pans make sautéing easier and help with cleanup!

Preparation Method

1. Preheat your oven to 375°F (190°C).
2. Cook the tortellini according to package instructions. Drain and set aside.
3. In a large skillet, heat olive oil over medium-high heat. Add the sliced steak and cook for 2-3 minutes per side, until browned. Remove steak and set aside.
4. In the same skillet, add more olive oil if needed. Sauté the onions, bell peppers, and garlic until softened, about 5 minutes.
5. Deglaze the skillet with beef broth, scraping up any browned bits for added flavor.
6. Reduce heat to medium and stir in heavy cream and Worcestershire sauce. Simmer for 2-3 minutes to thicken slightly.
7. Mix the cooked tortellini into the skillet, ensuring it’s evenly coated with the sauce.
8. Layer half of the tortellini mixture into a casserole dish. Add a layer of steak slices and sprinkle with shredded cheese. Repeat with the remaining tortellini, steak, and cheese.
9. Bake in the preheated oven for 20 minutes, or until bubbly and golden brown on top.
10. Let the casserole rest for 5 minutes before serving. Enjoy!

Pro tip: If the cheese isn’t browning enough, turn on your broiler for the last 2-3 minutes of baking.

Cooking Tips & Techniques

• Use fresh tortellini for faster cooking, but frozen works well too—just adjust the boiling time.
• Thinly slice the steak against the grain to keep it tender.
• Don’t skip deglazing the skillet! It adds so much flavor to the sauce.
• If the sauce seems too thick, add a splash of milk or broth to loosen it up.
• To save time, you can prep the veggies and steak ahead of time and store them in the fridge until ready to cook.

Variations & Adaptations

• Vegetarian version: Swap the steak for sautéed mushrooms or roasted tofu.
• Low-carb option: Replace the tortellini with zucchini noodles or cauliflower florets.
• Spicy twist: Add red pepper flakes or hot sauce to the sauce for a kick.
• Cheese swap: Use cheddar, gouda, or a blend for different flavor profiles.

My personal favorite variation? Adding a handful of chopped spinach for a pop of color and extra nutrients!

Serving & Storage Suggestions

This casserole is best served hot and bubbly straight out of the oven. Pair it with a crisp green salad or roasted veggies for a complete meal. A glass of red wine or iced tea complements the flavors beautifully.

To store leftovers, let the casserole cool completely before transferring to an airtight container. Refrigerate for up to 3 days or freeze for up to 2 months. To reheat, cover and bake at 350°F (175°C) until warmed through, or use the microwave for quicker results.
