To keep it low carb, make sure to use a low-carb tomato sauce, or even better, a homemade marinara sauce. Combine ground beef, egg, Parmesan cheese, flaxseed, oregano, salt, and pepper in a bowl; mix until well combined. Roll mixture into golf ball-size meatballs. Heat olive oil in a large skillet over medium heat.
Instructions Add the beef and pork to a medium bowl and break up into smaller chunks, aiming for an even mix. Add the remaining ingredients to the meat and mix with a hand mixer until just combined. Lightly oil hands and roll 12 meatballs.
Tender, juicy keto meatballs with lots of flavor are perfect for any low carb sauce. Make a big batch and freeze them to use as you need them. Just 0.5 net carbs per meatball, or 1.5 carbs per serving of 3. Preheat the oven to 350F.
Heat the sauce in the pan, scraping up the brown bits for a full flavored sauce. For a fresher tasting sauce, warm on the stove or in the microwave and pour over the meatballs. Garnish with parsley and serve or top with mozzarella cheese and place under the broiler to melt. Pre-heat oven to 400 degrees F and position rack to the middle.
