What Makes This a Keto-Friendly Meatball Recipe?

Traditional meatballs usually include breadcrumbs, which add carbs and can throw off your macros. This recipe swaps those out for low-carb binders like almond flour, grated Parmesan, or even pork rinds. The result is juicy, tender meatballs that taste just as good (if not better) than the classic version.

Paired with sugar-free marinara sauce and plenty of cheese, you end up with a low carb meatballs casserole that’s perfect for keto. It’s high in protein, rich in healthy fats, and low in net carbs. The flavors are bold, cheesy, and satisfying—exactly what you want in a comfort dish.

It’s the same concept that makes recipes like Keto Quiche such a hit—indulgence without the carbs.

• ½ teaspoon salt
• ½ teaspoon black pepper
• 2 cups sugar-free marinara sauce
• 2 cups shredded mozzarella cheese

This recipe keeps it simple yet flavorful, making it one of the best easy keto meatballs baked casseroles around.

Step-by-Step Instructions: How to Make Low-Carb Meatballs Parmesan Casserole

Step 1: Make the Meatballs
Preheat your oven to 400°F (200°C). In a large bowl, combine ground beef, Parmesan, almond flour, eggs, garlic, Italian seasoning, salt, and pepper. Mix until just combined—don’t overwork the meat.

Step 2: Shape and Bake
Form the mixture into meatballs, about 1 ½ inches in size. Place them on a greased baking sheet and bake for 15–20 minutes, until browned and cooked through.

Step 3: Layer the Casserole
Lower the oven to 375°F (190°C). Spread a thin layer of marinara sauce in the bottom of a casserole dish. Add baked meatballs in a single layer. Cover with the remaining sauce. Sprinkle mozzarella and Parmesan cheeses evenly over the top.

Step 4: Bake Until Bubbly
Bake uncovered for 20–25 minutes, until the cheese is melted and golden brown.

Step 5: Garnish and Serve
Let rest for 5 minutes before serving. Garnish with fresh basil or parsley for color and freshness.
