Amazing something so modest would result in such exquisite complex taste. The sauce speaks for itself. It will leave you speechless though, cause it's that good. Technique + quality ingredients equal deliciousness whether it's an instant pot or stovetop.

Crush the tomatoes using a potato masher or the blunt side of a meat tenderizer. Add the spices and cook for a few minutes more. Add drained tomato liquids to the pot, stir, and cancel saute.

Step 3:Finish the sauce

Close the lid and pressure cook manually for 25 minutes. Let sauce release naturally.

Serving Suggestions

The sauce is straight-forward but soooo good. I put it on any pasta dish with or without meat. Dress it up with whatever you like, but note it isn’t necessary.

Key Steps For Maximizing Flavor

  • Choose good quality canned tomatoes. I prefer San Marzano as they have a clean tomato taste and are fairly sweet. 
  • Fry your tomatoes first to not only concentrate their flavor but also to add flavor depth
  • Season the sauce well before pressure cooking. I like a combination of a good smoky paprika and dried oregano.
  • The longer the sauce rests/sits the more the flavor evolves into sweet baby Jesus levels!

Instant Pot Spaghetti Sauce Frequently Asked Questions (FAQs)

Do I Have To Use An Instant Pot?

Not at all. This instant pot recipe is actually converted from a traditional approach. The steps/approach for cooking in a saucepan are the same. The only difference is instead of pressure cooking, the tomatoes are cooked at a long long long low-temperature simmer. I’m talking at least 2 hours.

How Much Sauce Does This Recipe Produce

After cooking this sauce nets about 20 oz which is slightly less than a normal size jar of store-bought pasta sauce.

How Long Will The Sauce Keep For?

There are no preservatives so you have 3-4 days refrigerated to preserve the sauce. Feel free to freeze it for much longer preservation using large freezer bags or airtight containers.
