Ingredients

Makes 6 servings · serves 6

Main

  • 1 lb sirloin steak, cut into bite-sized pieces
  • 1 lb cheese tortellini

Sauce

  • 2 cups shredded mozzarella cheese
Contains: gluten, milk

Why this recipe works

The method of searing the steak before combining it with the other ingredients is crucial. This step creates a Maillard reaction on the surface of the meat, adding a savory depth that permeates the entire dish. Without this initial sear, the meat would simply steam, resulting in a bland flavor profile and a less appealing texture for the steak pieces.

Using mozzarella cheese as the primary topping provides the necessary meltability to create a cohesive crust. This creates a luxurious, golden layer that holds the ingredients together instead of allowing them to dry out.

The ratio of cheese ensures that the final result is satisfying, providing the perfect medium for the pasta and steak to mingle in the oven.

Notes and substitutions

When selecting the steak, look for a cut with moderate marbling, such as sirloin or ribeye. These cuts are tender enough to remain succulent after being baked, ensuring that the bites of meat are just as enjoyable as the pasta. Avoid very lean cuts, as they can become tough and dry during the final baking process in the oven.

For the best results, use a high-quality, full-fat mozzarella cheese. Freshly shredded cheese is highly recommended because it lacks the anti-caking agents found in pre-shredded varieties, which can inhibit proper melting.

This ensures a superior cheese pull and a smoother, more consistent texture in the final dish, elevating the overall quality from good to excellent.
