Instant Pot (Pressure Cooker) Tomato Sauce recipe – 15 minutes under pressure gives you a fantastic pasta sauce.
Jump to:
My plan seemed so simple – use pressure cooking to get the flavors of a long-simmering sauce in the time it takes to boil water and cook pasta. I’ve already got a stovetop quick tomato sauce recipe – it will be easy to convert, right?
Easy. Riiiight.
It’s time for another episode of “Why can’t I get this recipe to work the way I want it”?
I sauté some onions and garlic, add spices, pour in crushed tomatoes, and lock the lid on the pressure cooker. Five minutes under pressure is not enough time for flavors to mingle; the sauce comes out like a salsa, with distinct tomato and onion pieces. Fifteen minutes is just right – the sauce is thick, like it was simmered all afternoon by an Italian Nonna. (OK, OK, I don’t know what that would taste like. I don’t have an Italian grandmother – I’m a typical American mutt, mostly German and French.)
But…as I’m testing the recipe, every now and again, the sauce scorches on the bottom. I’m running right on the edge of overheating the pressure cooker; the thick, crushed tomatoes have just enough liquid to get up to pressure…most of the time. If the pressure valve doesn’t seal quickly, the heating element starts to burn the tomatoes before it switches from “high heat, bring to pressure” mode to “under pressure, low heat to maintain pressure” mode. To be safe, and to add more flavor, I add a half-cup of red wine before adding the tomatoes. Problem solved.
You don’t have to use wine – chicken broth or water will both do the trick of adding the extra liquid. Me? I find excuses to add wine into a recipe.
Now, if it was just me and my wife, I’d serve the sauce just like it comes out of the cooker, with some chunks in it. But the kids? Chunks in the sauce? They’re not having it. I take my stick blender to the sauce, pureeing it right in the pressure cooker pot.
So, after some fiddling around, I have it. A quick weeknight spaghetti sauce with minimal effort. It takes a little longer than my stovetop recipe…but it’s a much richer, fuller bodied sauce, with a lot less active effort. Once the pressure cooker is locked, there’s nothing to do but wait, and boil water for the pasta.
INGREDIENTS
1 tablespoon olive oil
1 large onion, minced
3 cloves garlic, crushed
½ teaspoon fine sea salt
1 teaspoon dried Italian seasoning (or dried basil)
Pinch red pepper flakes (optional)
½ cup red wine (or chicken broth, or water)
1 (28-ounce) can crushed tomatoes
1 teaspoon fresh ground black pepper
How to Pressure Cook Tomato Sauce
Sauté the aromatics
Set an Instant Pot or other pressure cooker to Sauté mode-high (medium-high heat for a stovetop PC) and pour in 1 tablespoon of olive oil. Wait for the oil to start shimmering, about 3 minutes. Add the onion and garlic and sprinkle with ½ teaspoon of salt. Add the Italian seasoning and the pinch of red pepper flakes, and give the pot a stir. Cook, stirring occasionally, until the onions soften, about five minutes.
Add the liquid and the tomatoes
Pour in the wine (or broth, or water). Bring to a simmer, scraping the bottom of the pot to loosen any stuck bits of onion. Stir in the crushed tomatoes.
Pressure cook for 15 minutes on high pressure
Lock the pressure cooker lid, then cook on high pressure for 15 minutes in an electric PC, or 12 minutes in a stovetop PC. Quick release the pressure by turning the pressure release valve. Once the pressure has dropped, remove the lid, tilting it away from you to protect yourself from the hot steam.
Season, purée, and serve
Stir in ½ teaspoon ground black pepper. If you like a chunky, rustic sauce, serve it as-is. If you want a smooth sauce, purée with a stick blender right in the pot before serving. Enjoy!
Variations
Buttery Sauce
Add a tablespoon of butter with the olive oil for extra rich sauce.
Chunky sauce
Replace the crushed tomatoes with diced tomatoes. (The timing stays the same).
This sauce stores beautifully. It will last for a few days in the refrigerator, or can be frozen for up to 6 months.
FAQs
What tomatoes should I use?
I like Muir Glen crushed tomatoes or San Marzano crushed tomatoes in this recipe, but any crushed tomatoes will do. (I make it with store-brand crushed tomatoes when they are on sale for cheap.)
How long does tomato sauce need when pressure-cooked?
Pressure cooked tomato sauce needs 15 minutes at high pressure with a quick pressure release.
Can I use canned tomatoes instead of fresh ones?
This recipe is made for canned tomatoes, so yes, absolutely. (If you want to use fresh tomatoes, you’ll have to find a different recipe – they don’t work for a quick weeknight sauce.)
How do I thicken pressure cooker tomato sauce?
If you want thicker sauce, after pressure cooking, set your Instant Pot to Sauté mode – Low (Medium-low for a stovetop PC) and simmer the sauce for 15 minutes, stirring often to make sure the tomatoes don’t scorch in the bottom of the pot.
Should I add Sugar?
I’m not a fan of adding sugar to my tomato sauce; I think modern tomatoes are sweet enough straight out of the can. That said, if you want a little sweeter sauce, add 1 teaspoon of sugar with the crushed tomatoes.
