Tools You’ll Need

• Low-carb option: Use cauliflower florets instead of tortellini.

How to Make

1. Preheat and Prep: Preheat your oven to 375°F (190°C). Grease a 9×13 casserole dish.
2. Cook the Tortellini: Boil tortellini just until al dente, about 3–4 minutes. Drain and set aside.
3. Sear the Steak: Heat olive oil in a skillet over medium-high heat. Add steak slices and cook for 2–3 minutes per side until browned. Remove and set aside.
4. Sauté Veggies: In the same skillet, add onions and peppers. Sauté until softened, about 5 minutes. Add garlic and cook 1 minute more. Stir in Worcestershire sauce and season with salt, pepper, and Italian seasoning.
5. Make the Cheese Sauce: In a medium saucepan, melt butter over medium heat. Whisk in flour and cook for 1 minute. Slowly whisk in milk and cream, stirring until thickened. Add 1 cup mozzarella and 1/2 cup provolone, stirring until melted and smooth.
6. Combine: In a large bowl, mix cooked tortellini, steak, veggies, and cheese sauce. Stir until coated evenly.
7. Assemble: Pour mixture into prepared baking dish. Top with remaining mozzarella and provolone.
8. Bake: Bake uncovered for 20–25 minutes, until bubbly and golden.
9. Serve: Garnish with parsley and serve warm — cheesy perfection in every bite!

What to Serve With

This casserole pairs beautifully with a crisp green salad, roasted broccoli, or garlic bread to soak up the creamy sauce. For a heartier dinner, serve with a side of roasted potatoes or a glass of red wine.

Why It’s Perfect for Family Dinners

This dish is rich and satisfying enough for adults but mild and cheesy enough for kids. It’s the perfect way to bring everyone to the table — no complaints, just clean plates and smiles. And since it’s baked in one dish, cleanup is a breeze.

Tips for Success

• Slice steak thinly: It cooks quickly and stays tender.
• Don’t overcook tortellini: It will continue cooking in the oven.
• Use freshly shredded cheese: It melts more smoothly than pre-shredded.
• Rest before serving: Let the casserole cool for 5 minutes before scooping so the sauce sets slightly.

Common Mistakes to Avoid

• Overcooking the sauce: Keep it creamy, not too thick.
• Skipping seasoning: The right salt, pepper, and Worcestershire balance the richness.
• Crowding the pan when searing steak: Work in batches for proper browning.
• Using frozen tortellini without thawing: It can make the dish watery.

How to Store & Reheat

Store leftovers in an airtight container for up to 4 days in the refrigerator. To reheat, bake at 350°F for 15 minutes or microwave individual portions with a splash of milk to keep it creamy. It also freezes beautifully for up to 3 months — thaw overnight and reheat for an easy meal.
