Ingredients Method

Ingredients
  

  • 1½ lb ground meat
  • 1 large egg
  • ⅓ cup almond flour
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • Salt and pepper to taste
  • 2 cups low-carb marinara sauce
  • 1½ cups shredded cheese

Method
 

  1. Start by adding the ground meat to a large mixing bowl, then crack in the egg and add the almond flour, seasonings, salt, and pepper. Using your hands or a spoon, gently mix everything together just until the ingredients are evenly combined. Be careful not to overmix, as working the meat too much can make the meatballs dense instead of tender and juicy.
  2. Scoop portions of the mixture and roll them between your palms to form evenly sized meatballs. Keeping the meatballs uniform helps them cook at the same rate and ensures consistent texture throughout the casserole. Place the shaped meatballs on a plate or tray and set them aside while you heat the skillet.
  3. Heat a skillet over medium heat and add a small amount of oil, allowing it to warm until shimmering. Add the meatballs in a single layer, working in batches if necessary to avoid overcrowding the pan. Brown the meatballs gently on all sides, turning them carefully so they hold their shape. At this stage, you are building flavor and structure rather than fully cooking them through.
  4. Once the meatballs are lightly browned, transfer them carefully into a baking dish, arranging them in a single, even layer. Pour the marinara sauce evenly over the meatballs, using a spoon to help the sauce settle between them so each one is coated and surrounded by moisture.
  5. Sprinkle the shredded cheese evenly over the top of the sauce-covered meatballs. Let the cheese fall naturally without pressing it down, which allows it to melt evenly and form a lightly golden, bubbly layer as the casserole bakes.
  6. Place the baking dish into the preheated oven and bake until the sauce is bubbling around the edges and the cheese is fully melted with a light golden color on top. The bubbling indicates that the casserole is heated through and the flavors have come together.
  7. Remove the casserole from the oven and let it rest for a few minutes before serving. This short resting time allows the sauce to thicken slightly and helps the meatballs hold their shape, making the casserole easier to serve and even more enjoyable to eat.
