Instant Pot Marinara Sauce tastes tastes rich and robust like it has been simmering all day but is ready in about an hour in the Instant Pot pressure cooker.

I love the taste of homemade Marinara Sauce! It is rich, garlicky, and so flavorful with all the Italian herbs and seasonings. However, I often don’t have all day to wait for the sauce to simmer for hours to get that delicious flavor!

Enter the Instant Pot! It is fabulous for speeding up the cooking process but maintaining rich flavors. My Instant Pot Recipe Collection reflects my love of this pressure cooker.

By pressure cooking the marinara sauce in the Instant Pot, the marinara sauce cooks much faster yet develops that same rich flavor in only about an hour.

It tastes fabulous on spaghetti, meatballs, like my Baked Italian Meatballs, or Porcupine Meatballs, or in my Lasagna Soup or Tortellini Lasagna, or topping the Best Chicken Parmesan, or even as a dipping sauce for Toasted Spinach Pesto Ravioli.

Furthermore, it has no preservatives and is basically all vegetables and seasonings. So it is a sauce that everyone, including vegans can enjoy.

Equipment

6-quart Instant Pot Duo60 from Amazon.com (affiliate link) - I use the 6-Quart Instant Pot Duo for my recipes. However, they have many models of Instant Pot, including in a 3-quart size, or an 8-quart size.
Chef's Knife from Amazon.com (affiliate link)
Immersion Blender – (Amazon Affiliate Link) You will need this to blend the sauce in the Instant Pot after cooking. You could also pour the marinara sauce in a blender or food processor, but I like the Immersion Blender best. It is the easiest option.

Ingredients

Oil. You just need a little oil to sauté the onions and garlic.
Tomatoes. I have written the recipe for canned tomatoes since that is what most readers will have on hand year round. However, if you have fresh tomatoes, by all means use them as they will add the freshest flavor.
Onion. I chopped up a white onion. However, you could use a yellow onion, sweet onion, or Vidalia onion, whatever you have on hand.
Garlic. I recommend using fresh garlic for the most flavorful sauce.
Liquid. For the Instant Pot, you need a thin liquid to pour on the bottom of the pot. You could use water, broth (vegetable or chicken), or red wine as your thin liquid.
Herbs and Seasonings. Dried oregano, thyme. I like to use fresh basil but you could use dried basil if you have that on hand. Also, If you have the herb blend called Italian Seasoning, then you could use that as well. If you like a little spicy heat, then add a little crushed red pepper.
Sugar (Optional). To cut the acidity in the recipe, you can add a little sugar in the sauce after pressure cooking and before blending with the immersion blender.

How To Make Instant Pot Marinara Sauce

Sauté the Onions and Garlic.
1. Using the Saute function, add oil and cook the onion until soft and then add the garlic for about a minute.
Deglaze the pot.
1. Add a 1/2 cup of thin liquid (water, broth, red wine) to deglaze the pot and prevent the onions and garlic from sticking to the bottom of the pot. This will help prevent getting the burn message.
Add the Tomatoes and seasoning.
1. Add the diced tomatoes (either can or fresh) and then add the salt, pepper, oregano, thyme, basil, and crushed red pepper (if desired.)
Pressure Cook.
1. Pressure Cook for 25 minutes with high pressure.
Natural Release.
1. Allow for a natural release for 15 minutes. This means that you do nothing for 15 minutes.
Add Sugar.
1. If you would like to cut the acidity of the sauce, add a tablespoon of sugar after pressure cooking and the natural release.
Blend the Sauce.
1. Use an immersion blender to blend the sauce.
Thicken The Sauce.
1. If you would like a thicker sauce, use the SAUTE function to heat the sauce for 5 or 10 minutes.

Recipe Tips

Avoid the Instant Pot Burn Message!
- Always deglaze the pan by adding a little liquid and scraping the bottom of the pot with a wooden spoon to keep ingredients from burning on the bottom of the pot.
- Add the liquid, such as water, broth, or wine BEFORE adding the tomatoes and seasonings. Having a think liquid on the bottom of the pot helps to prevent getting the burn message.
- Add the tomatoes and seasonings last! This is to keep the tomatoes and herbs and seasonings off the bottom of the pot to prevent them from burning. The tomatoes are thick and acidic and can cause the burn message.
- DO NOT STIR!! If you don’t stir, you can to keep the tomatoes and seasonings off the bottom of the pot to avoid them from burning.
Use quality ingredients.
- If you have fresh tomatoes, then by all means use them. See the printable recipe card below for the correct amount of fresh tomatoes to equal the same amount. However, I have written the recipe primarily for canned tomatoes since that is what most people will have on hand year-round.
- Fresh garlic makes a difference.
- For the liquid, if you use vegetable broth or chicken broth, I recommend using a low-sodium broth so that the sauce is not too salty and you have more control over how much salt goes into the sauce.
- If you use red wine, use a red wine that you like. If you don’t like red wine, then don’t use it. However, if you are going to use a red wine, I recommend using a red wine that you actually like to drink and not a cooking wine that is only used for cooking. You will get a better flavor using a drinking red wine that you like.
Make The Recipe In Advance
- Yes, you can make this marinara sauce in advance and in this case, I actually recommend that you do that. You don’t have to, but you will be happy if you do. Why? It is because if you allow the sauce to sit for hours, or overnight, it allows the flavors to develop even more to provide a more rich, robust, and flavorful marinara sauce.
Add A Little Sugar
- To cut the acidity, add a little sugar, about a tablespoon, to the marinara sauce after it pressure cooks and before you blend it with the immersion blender. This is optional, but some people prefer to offset the acidity of the tomatoes and the sugar does that.
Customize The Texture Of the Sauce
- You control the texture of the sauce meaning how chunky or how smooth the sauce is by how long you blend it. If you want the sauce to be a little chunky, just blend a short time, pulse it, so you can check the chunkiness of the sauce periodically. If you like it thinner, then blend it a little longer until the sauce is smooth and not chunky.
Adjust The Thickness Of the Sauce
- The pressure cooker requires a minimum amount of liquid to come up to pressure. However, this can sometimes make the sauce a little on the thinner side. If you would like to thicken the sauce after pressure cooking and blending with the Immersion blender, then select the SAUTE button and sauté for 5 or 10 minutes or until the sauce is your desired thickness.
