  • 4 bulbs of roasted garlic bulbs, not cloves
  • 1 onion dquartered
  • Pinch of red pepper flakes
  • 1 TBS oregano
  • 1 TBS sugar to neutralize the acidity of the tomatoes
  • 2 TBS dried basil or ½ cup ripped fresh basil
  • 3 cans 796mL diced tomatoes (OR 4 pounds roma tomatoes plus 1 cup water)
  • 1 can 284ml tomato paste (2 cans if you are using fresh tomatoes)
  • 2 large clove of garlic unroasted


  • Roast garlic cloves in the oven by slicing the tapered end off, covering with tin foil, drizzling with olive oil, and roasting for 40 minutes at 400F
  • Once garlic is roasted, add all remaining ingredients into the instant pot liner.
  • Secure the lid on the Instant Pot, seal the pot, and set on high pressure for 10 minutes.
  • Once the 10 minutes is up, allow the pot to NPR for 10 minutes (you don't want to risk tomato sauce on your ceiling!).
  • Quick release remaining pressure.
  • Allow to fully cool before freezing the sauce.


With pressure up time, this recipe takes about an hour in your Instant Pot.
