Ingredients

Instructions

  • Preheat oven to 400°F. Adjust the oven rack to the middle position and butter a casserole pan. Set aside.
  • In a medium skillet, add olive oil over medium heat. Add onions and sauté for about 5 minutes.
  • Meanwhile, combine ground beef, keto breadcrumbs, parmesan, parsley, egg, garlic powder, onion powder, dried basil, salt and black pepper in a large salad bowl. Then, add the sauteed onions and mix everything well to combine.
  • Use a small cookie scoop to form the meatballs all the same size. Place the meatballs in the prepared casserole dish.
  • Bake them for 15 to 20 minutes or until fully cooked. Remove the meatballs casserole from the oven and drain the grease.
  • Top with the tomato sauce and shredded cheese.
  • Place the meatballs casserole back in the oven. Bake for an additional 5 minutes until the cheese has fully melted.
  • Meal-Prep: Place an even amount of meatballs, any veggies of your preference, and mashed cauliflower into 5 glass containers. Cover with the lid, and place in the fridge for up 5 days. Heat in the microwave for about 1½ - 2 minutes. The time depends on the power of your microwave.
