Ingredients

Main Ingredients

  • 1 lb ground beef
  • 1 lb ziti pasta, uncooked
  • 1 packet garlic seasoning
  • 24 oz marinara sauce
Contains: gluten

Why this recipe works

The slow cooking method allows the pasta to absorb the moisture and flavor from the marinara sauce, resulting in a more integrated dish than boiling the pasta separately. The low heat ensures the ground beef remains tender while infusing the entire casserole with savory aromatics from the garlic seasoning.

Cooking everything in one vessel minimizes cleanup and simplifies the preparation process. By layering the ingredients properly, the heat circulates evenly, ensuring that the pasta cooks through without becoming mushy.

Notes and substitutions

For the best results, use a high-quality marinara sauce, as it serves as the primary flavor base for the entire dish. If the sauce appears too thick, you can add a quarter cup of water or beef broth to help the pasta cook properly.

Ensure the ground beef is distributed in small, bite-sized crumbles to prevent large clumps from forming during the cooking process.

When selecting pasta, ziti is ideal because its tubular shape holds the sauce well, but penne or rigatoni are excellent alternatives if ziti is unavailable.

Adjust the amount of garlic seasoning based on personal preference for more or less aromatic depth in the final dish. Always ensure the slow cooker is not overfilled to allow for proper heat circulation throughout the cooking cycle.
