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
1 package (20 oz) cheese tortellini, fresh or refrigerated
½ cup shredded mozzarella (for topping)
2 tbsp chopped parsley (for garnish)
Instructions
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.
In the same skillet, melt butter over medium heat. Add minced garlic and cook for 30 seconds. Stir in flour to make a roux and cook for 1 minute. Gradually whisk in milk and beef broth until smooth. Stir in cheddar cheese, Dijon mustard, and paprika until creamy.
Cook tortellini according to package directions, slightly undercooking them. Drain and toss with a small amount of olive oil to prevent sticking.
Grease a 9×13″ baking dish. Combine tortellini, seared steak, and cheese sauce in the dish. Stir gently to mix evenly. Sprinkle shredded mozzarella on top.
Bake uncovered for 20–25 minutes, until cheese is bubbly and golden. Garnish with chopped parsley before serving.
