Ingredients
Scale
Meatballs
- 2 lbs ground beef (grass fed)
- 2 tablespoons garlic
- 1 teaspoon onion powder
- 1 tablespoon oregano
- 2 teaspoons cracked black pepper
- 1 teaspoon salt
- 1/2 cup parmesan cheese
Sauce & Toppings
- 1 – 28 oz jar of spaghetti sauce
- 6 buns
- 6 slices mozzarella cheese (optional)
- Extra parmesan cheese for topping (optional)
Instructions
- Prepare the Meatballs: In a large bowl, combine the ground beef with salt, cracked black pepper, parmesan cheese, garlic, onion powder, and oregano. Mix thoroughly using your hands or a hand mixer until all ingredients are evenly combined. Roll the mixture into meatballs.
- Chill the Meatballs: Place the rolled meatballs into the freezer for about one hour. This helps them firm up and retain shape while cooking. If freezing longer, expect to increase the cook time accordingly.
- Pressure Cook the Meatballs: Place the trivet inside the Instant Pot and add one cup of water. Arrange the chilled meatballs on the trivet. Secure the lid and seal the valve. Set the Instant Pot to high pressure cooking for 13 minutes. Once cooking is complete, perform a quick release of the pressure.
- Simmer with Sauce: Remove the meatballs carefully and drain the cooking liquid. Place the meatballs back into the Instant Pot without the trivet. Use the sauté function to add the spaghetti sauce and gently stir to coat the meatballs. Allow the sauce to heat up, then turn off the sauté mode and set the pot to keep warm.
- Assemble the Subs: Slice and toast the buns. Fill each bun with several meatballs topped with parmesan and a slice of mozzarella cheese. Serve immediately, optionally topping with extra parmesan cheese for added flavor.
Notes
- Freezing meatballs longer than 1 hour requires additional cooking time; monitor doneness carefully.
- Use grass-fed beef for a richer flavor and healthier option.
- The mozzarella cheese is optional but adds a nice melty texture.
- To toast buns, use a toaster oven or skillet on medium heat until golden brown.
- Be sure to quick release pressure carefully to avoid overcooking the meatballs.
