Step‑by‑Step Instructions for Gooey Cheesy Keto Meatball Casserole
Step 1: Prepare the Meatball Mixture
In a large mixing bowl, gently combine the ground beef, ¼ cup of grated Parmesan cheese, the egg, grated onion, minced garlic, chopped parsley, onion powder, garlic powder, dried Italian seasoning, and a pinch of salt and pepper. Mix until just combined, ensuring not to overwork the meat. This step is essential for tender meatballs that will shine in your Gooey Cheesy Keto Meatball Casserole.
Step 2: Form and Brown Meatballs
Shape the meat mixture into 1 to 1.5-inch meatballs and set them aside. Heat a tablespoon of olive or avocado oil in a skillet over medium heat, then add the meatballs in batches. Brown them for about 5-7 minutes, turning to get a golden crust on all sides. Once browned, transfer the meatballs to a plate and maintain their warmth as you prepare the sauce.
Step 3: Prepare Marinara Sauce
In the same skillet, lower the heat and add a touch more oil if needed; sauté any remaining minced garlic for about 30 seconds until fragrant. Next, pour in the keto-friendly marinara sauce, stirring well to incorporate the flavors from the skillet. Season with salt and pepper to taste, allowing the sauce to warm through while you prep the casserole next.
Step 4: Preheat Oven and Assemble Base
Preheat your oven to 375°F (190°C). While it warms, grease a baking dish generously to prevent sticking. Spread half of the prepared marinara sauce at the bottom of the dish, ensuring an even layer, which will serve as a flavorful base for your delectable Gooey Cheesy Keto Meatball Casserole.
Step 5: Add Ricotta and Meatballs
Evenly dot the ricotta cheese over the marinara sauce, making sure to distribute it across the surface. Then, place the browned meatballs on top of the ricotta, spacing them out so each one gets a taste of the delicious marinara sauce and cheeses to come.
Step 6: Layer with Sauce and Cheese
Spoon the remaining marinara sauce over the meatballs, covering them thoroughly. Then, generously sprinkle the shredded mozzarella and the remaining Parmesan cheese over the entire casserole. This cheesy layer will melt beautifully and create that irresistible gooey texture.
Step 7: Bake the Casserole
Place the casserole in the preheated oven and bake for approximately 25-35 minutes, or until the cheese is melted, bubbly, and golden brown. Keep an eye on the cheese; if it starts to brown too quickly, tent with aluminum foil to prevent burning while the meatballs finish cooking.
Step 8: Rest and Serve
Once baked, remove the casserole from the oven and allow it to rest for 5-10 minutes. This resting period allows the flavors to meld beautifully, making every bite of your Gooey Cheesy Keto Meatball Casserole even more enjoyable. Garnish with fresh basil, if desired, before serving.

Expert Tips for Gooey Cheesy Keto Meatball Casserole
• Gentle Mixing: Avoid overmixing the meatball mixture. This keeps your meatballs tender and prevents them from becoming tough in your Gooey Cheesy Keto Meatball Casserole.
