Ingredients Method Notes

Ingredients
  

  • 1 lb sirloin steak or steak tips cut into bite-sized pieces
  • salt & black pepper to taste
  • 1 tbsp olive oil
  • 2 tbsp butter
  • 3 cloves garlic minced
  • 1 tbsp all-purpose flour
  • 2 cups milk whole milk or 2%
  • 1 cup beef broth
  • 2 cups shredded sharp cheddar cheese or golden cheddar blend
  • 1 tsp Dijon mustard optional
  • 1 tsp paprika
  • 20 oz cheese tortellini fresh or refrigerated
  • 1/2 cup shredded mozzarella for topping
  • 2 tbsp parsley chopped, for garnish

Method
 

  1. Preheat oven to 375°F (190°C). Season steak with salt and pepper. Heat olive oil in a skillet over medium-high heat and sear steak for 2–3 minutes per side until browned. Remove and set aside.
  2. In the same skillet, melt butter over medium heat. Add garlic and cook 30 seconds. Stir in flour and cook 1 minute. Gradually whisk in milk and beef broth until smooth. Stir in cheddar cheese, Dijon mustard, and paprika until creamy.
  3. Cook tortellini according to package directions, slightly undercooking them. Drain and toss with a small amount of olive oil to prevent sticking.
  4. Grease a 9×13-inch baking dish. Combine tortellini, seared steak, and cheese sauce in the dish. Stir gently to mix evenly. Sprinkle mozzarella on top.
  5. Bake uncovered for 20–25 minutes, until cheese is bubbly and golden. Garnish with chopped parsley before serving.

Notes

For added flavor, try adding sautéed onions or mushrooms to the casserole. Use freshly shredded cheese for a smoother sauce and better melting.
