Ingredients

16 ounce ground beef (85/15)
16 ounce Italian sausage (ground)

2 large eggs
1/2 teaspoon salt

1/2 teaspoon black pepper
1/2 teaspoon onion powder

1/4 cup Parmesan cheese (grated finely)
14 ounce pizza sauce
2 tablespoon tomato paste

1/2 cup mozzarella cheese (grated)
1/4 cup Parmesan cheese

Instructions

Step 1: Preheat your oven to 400°F (200°C).

Step 2: In a large bowl, mix together the ground beef, Italian sausage, eggs, salt, pepper, onion powder, and 1/4 cup of finely grated Parmesan cheese until well combined. Then, shape the mixture into meatballs by hand.
Step 3: Heat a little oil in a pan over high heat. Sear the meatballs on a few sides without crowding the pan. They only need to be browned as they will finish cooking in the oven.
Step 4: Remove the meatballs from the pan and reduce the heat to medium. Add the tomato paste and cook for about 10 seconds to deepen its flavor. Stir in the pizza sauce, then return the meatballs to the pan and turn off the heat.

Step 5: Sprinkle the tops of the meatballs with shredded mozzarella and Parmesan cheese. Place the pan uncovered in the preheated oven and bake for 20 minutes, or until the cheese is browned and the meatballs are cooked through.

Tips & Variations

Use a mix of beef and pork sausage for a richer flavor and juicier meatballs.
If you prefer, swap the pizza sauce for a homemade low-carb marinara sauce to control ingredients.

For extra moisture, soak the meatballs in cold water for a few minutes before shaping to help them stay tender.
Try adding fresh herbs like parsley or basil to the meatball mix for added freshness.

Storage

Store leftover meatballs and sauce in an airtight container in the refrigerator for up to 3 days. Reheat gently in a pan over low heat or in the microwave until warmed through. You can also freeze cooked meatballs in sauce for up to 3 months; thaw overnight in the fridge before reheating.
