  • Method: Instant Pot
  • Cuisine: American


For the Meatballs

  • 1 lb ground pork
  • 1 lb lean ground beef
  • 1 egg
  • 1/2 cup almond flour
  • 1/2 tbsp dried basil
  • 1/2 tbsp dried oregano
  • 2 tsp dried parsley
  • 1 tsp onion powder
  • 1 tsp garlic powder
  • 1/2 tsp ground fennel
  • 1/2 tsp salt

For the Soup

  • 1 green pepper, diced
  • 1 red pepper, diced
  • 1.5 cups sliced mushrooms
  • 1 medium white onion, diced
  • 1 (14 oz) can diced tomatoes with liquid
  • 1 (4 oz) can sliced black olives, drained
  • 2 cups Primal Kitchen Tomato Basil Marinara
  • 2 cups beef broth (can substitute chicken broth or water)
  • 1 tbsp dried basil
  • 1 tbsp dried oregano
  • 1/2 tbsp dried parsley
  • 2 tsp dried thyme
  • 2 tsp dried minced onion
  • 1 tsp garlic powder
  • 1 tsp salt


  1. Prep all of the ingredients first (chop veggies, open cans), and coat the bottom of the instant pot in a light layer of spray cooking oil.
  2. In a large bowl, combine all of the meatball ingredients and use your hands to combine. Roll the mixture into meatballs (about 1 inch in diameter) and place directly into the bottom of the instant pot.
  3. Do this until all of the meat has been rolled into meatballs. Place them in the instant pot so they are touching, but not smooshed in there tightly. Once the bottom of the pot has been covered by meatballs, begin a second layer by placing meatballs in the spaces between the meatballs on the first layer.
  4. Once all of the meatballs are formed, add in the fresh vegetables, and then the canned tomatoes and olives, and then the spices, and lastly, pour the marinara and broth over the top.
  5. Do not stir. Place the lid on, set the valve to “sealing” and then set the instant pot to manual high pressure for 10 minutes.
  6. Once the time is up, do a quick release and remove the lid. Gently stir, and serve. Top with any extra “pizza toppings” you’d like, like additional black olives, fresh parsley or basil, or cheese if you’re not dairy-free.


  • You can use pizza sauce in place of marinara, but you will need to reduce the amount of dried spices that are used to create the pizza sauce flavor.
