Recipe Ingredients

  • 1 pound ground beef
  • 1 pound ground pork
  • 1 small onion, finely chopped
  • 1 tablespoon minced garlic
  • 1 tablespoon Italian seasoning
  • salt and ground black pepper to taste
  • 1 ¼ cups bread crumbs
  • ¼ cup milk, or more as needed
  • 2 tablespoons mayonnaise
  • 3 (30 ounce) jars marinara sauce, or as needed
  • 1 cup water

Cooking Directions

  1. 1 Combine beef, pork, and onions in a large bowl using your hands or a spoon. Halfway through mixing, add garlic, Italian seasoning, salt, and pepper and mix well.
  2. 2 Combine bread crumbs, milk, and mayonnaise in a small bowl until you get a thick consistency, adding more milk if needed. Mix into meat mixture until thoroughly combined.
  3. 3 Form golf ball-sized meatballs and place on a plate or a pan.
  4. 4 Combine marinara sauce and water in a multi-functional pressure cooker (such as Instant Pot®). Place meatballs in sauce, making sure meatballs are covered at all times, adding sauce and stirring if needed. Close and lock the lid. Select high pressure according to manufacturer's instructions; set timer for 10 minutes. Allow 10 to 15 minutes for pressure to build.
  5. 5 Release pressure carefully using the quick-release method according to manufacturer's instructions, about 5 minutes. Unlock and remove the lid. An instant-read thermometer inserted into the center of a meatball should read at least 165 degrees F (74 degrees C).

Chef's Notes

After forming the meatballs, you can use your Instant Pot(R) or skillet to sear the meatballs if you choose. I did not, and it came out amazing; You should fill your Instant Pot(R) to the halfway mark with sauce. You can use any sauce of your choosing; Nutrition data for this recipe includes the full amount of marinara sauce. The actual amount of sauce consumed will vary.


  1. Delicious and easy. I made a little less than half a recipe an used one jar of sauce. I think a full recipe with 3 jars and maybe a little more water would be perfect
