• 1 tsp dried Italian seasoning – Infuses classic Italian flavors.
• ½ tsp salt – Brings out the flavors.

How to Make Keto Meatball Casserole

1. Preheat the oven to 375°F (190°C). Grease a baking dish and set aside.
2. Make the meatballs. In a mixing bowl, combine ground beef, ground pork, egg, Parmesan, almond flour, garlic, Italian seasoning, salt, and pepper. Mix until just combined.
3. Form meatballs. Shape the mixture into golf ball-sized meatballs.
4. Sear the meatballs. Heat olive oil in a skillet over medium-high heat. Sear the meatballs for 2-3 minutes on each side until browned.
5. Assemble the casserole. Transfer the seared meatballs to the baking dish. Pour marinara sauce over them, ensuring they are well coated.
6. Add cheese. Sprinkle shredded mozzarella and cheddar cheese over the meatballs.
7. Bake for 25-30 minutes. Bake until the cheese is melted and bubbly.
8. Serve and enjoy! Let the casserole cool for a few minutes before serving.
