Keto Pizza Sauce (Big Batch in the Pressure Cooker)

A lot of people spend more than they need to on jarred keto pizza sauce, and the taste rarely lives up to the price. Keto pizza sauce made at home costs a fraction of what the commercial jars run, and takes almost no hands-on effort.

A pressure cooker turns this into a genuinely fast recipe, cooked-all-day flavor in well under an hour. If you do not have one, a covered pot on low heat or a slow cooker both work fine too.

Jarred sauces are also hard to fix once they are too sweet. This one can be tweaked as herby, spicy, or simple as you want from the start.

Chef Jenn’s Take on Keto Pizza Sauce

Crushed tomatoes are the right call here, not diced or whole. Crushed gives you a smooth sauce, while diced makes something chunkier, which is only what you want if that’s the texture you’re after on purpose. Check the can for one with no added sugar or salt, so you control the seasoning yourself.

The water matters more than it seems like it should. Some batches stick a little to the bottom of the pot during cooking, not burned, just stuck. If that happens, do not scrape it up. Empty the pot without dislodging that layer, then let it soak before washing.

If you’re strict keto, use grass-fed butter. For lazy or dirty keto, regular butter is completely fine.

This sauce is genuinely forgiving on seasoning. Add onion powder, garlic powder, more or less Italian seasoning, or a pinch of red pepper flakes to match your own taste.

The cost math alone makes this worth doing. Commercial keto pizza sauce often runs somewhere around seventy cents an ounce, while a homemade batch like this costs closer to a nickel an ounce.

Peel and crush, or roughly chop, the garlic. Open the cans of crushed tomatoes and add all the ingredients to the pressure cooker.

Set the pressure cooker to manual, high pressure, for 15 minutes. Let it release naturally for 10 minutes before pressing the release button to bring the pressure down.

Make It A Meal

This sauce is the base for my Sausage Parmigiana, and it works just as well in Chicken Parmesan Lettuce Wraps if you want something lighter.

Storage

Store in an airtight container in the fridge for up to a week. This freezes beautifully in quart-size freezer bags for up to 3 months. Thaw in hot water for a few minutes, or in the microwave, whenever you need a batch ready to go.
