Ingredients

  • 1/2 Pound Ground breakfast sausage or Italian sausage
  • 2 Pounds Ground beef
  • 1/2 Cup Grated Parmesan cheese
  • 1/3 cup Chopped fresh parsley
  • 2 cloves Garlic, minced
  • 2 Tablespoons Olive oil
  • 2 Large Eggs, beaten
  • 1 1/2 teaspoons Kosher salt
  • 1/2 teaspoon pepper
  • 1 24 oz Jar Marinara (click here to see my favorite brand)
  • 2 Cups Shredded Mozzarella Cheese

Instructions

  • Preheat your oven to 350F and spray a 9x9 casserole dish with cooking spray.
  • Combine ground beef, sausage, parmesan, parsley, olive oil, eggs, garlic, salt and pepper in a large mixing bowl. Careful not to overwork the meat.
  • Roll your mixture into 12 -13 meatballs.
  • Spray avocado oil in a large skillet and fry each meatball over medium heat until brown on all sides. Use a non stick skillet with the spray oil for even more assurance that your meatballs do not stick.
  • Place your meatballs inside a 9x9 casserole dish. Add the jar of marinara sauce around the meatballs
  • Sprinkle the shredded mozzarella cheese evenly over the top of the meatballs.
  • Bake in the oven for 20 minutes or until an internal meat thermometer reads 165F in the center of the meatballs. If you would like your cheese to get a little more brown, you can set your oven to broil for a few minutes extra.
  • Serve.

Notes

  • Use Frozen Meatballs for an even quicker dish: Frozen meatballs will work in this recipe, but since frozen meatballs are generally smaller you would use more.  Fill the bottom of the casserole dish with the meatballs.  Note that store bought frozen meatballs are a little higher in carbs than these homemade ones.
  • Jar Marinara: The one I have linked is my favorite keto friendly marinara but you can use any brand that is your favorite.  Look for one that has no sugar added.  You can also make your own with my recipe for keto marinara sauce.
  • Ground Beef: I use 85/15 ground beef for this recipe 
  • Pre-shredded Cheese: I always use pre-shredded cheese and this fact is reflected in the nutrition info.  You can shred your own if you like.
