My recent visit to Italy shattered my knowledge towards the pasta, pizza, and the base tomato sauce. Italian pasta is not loaded with cheese as here in the United States. I personally find the low cheese Italian pasta are equally tasty like the American cheesy pasta.
The new awareness of the health and body made me rethink the quantity of cheese in each serving portion. Though I like to have cheese, I started to minimize the quantity and also started omitting wherever I could.
And this Instant pot marinara sauce is one such lifesaver for me when I see to cut down my cheese content.

What is marinara sauce?
Marinara sauce is usually made with tomatoes, onion, garlic, and other Italian herbs. This sauce belongs to American-Italian cuisine.
And there are many variations in making it. I'm sharing here is the primary, simple recipe, where you can alter and customize according to your diet and menu.
Tomato sauce vs. marinara sauce
The term Marinara sauce has limited to the basic pasta sauce. Which is typically prepared with tomato, olive oil, garlic, and basil. Whereas Tomato sauce is a broad term, it has multiple variations of making and numerous choices of ingredients.
Like in this Instant pot marinara sauce, Tomato sauce can be made with including marinara, meat, seafood, wine, and stock.
Why Instant pot for making marinara sauce?
- The Instant pot easily cuts down both time and effort. Using Instant pot is very efficient when talking about the time and the effort.
- Preparing is effortless and does not need a large saucepot.
- Cleaning is like a breeze. I have tried making the sauce with large saucepans and soup pots. But I will end up in cleaning the stove and the kitchen counter a lot more than I thought.
- No splatters. Since the sauce is cooked with the lids on, and no splatters even on the Instant pot lids.
- Saves time. In this homemade tomato sauce recipe, you can saute the tomatoes and set the timer. Usually, this process takes 20 minutes to cook time in the stovetop method. Where you need not keep an eye for the burnt bottom.
How to thicken the spicy marinara sauce
The sauce made with the ingredients listed for Instant pot marinara sauce will yield a perfect flowy consistency of the spicy sauce like this Cajun butter sauce. If you prefer a thick consistency, you may follow any of these simple ideas.
- When you plan to thicken the sauce in the Instant pot, leave the sauce in the inner stainless steel pot. And set the electric pressure cooker in the saute mode. And allow it to cook without the lids. This helps the moisture to evaporate and helps the sauce to thicken.
- If the sauce is too thin, and you do not have enough time to heat it. Then strain the excess water and cook it till it gets reduced. But beware, since you are straining up the juices, there is some possibility that the taste of the sauce will also get diluted. So plan accordingly.
- You may also add onion powder, garlic powder to thicken up.
- Add bread crumbs. This has the potential to change the consistency of the sauce.
- Add cheese and reheat. The cheese acts as the binding agent and brings the sauce together and stick to the pasta.
- Add corn starch or all-purpose flour diluted in the water and reheating.
Cooking With Pressure Cooker
This Italian marinara sauce can be made not only in Instant pot but in the pressure cooker as well. When using the pressure cooker, follow the same procedure as mentioned below until the step of sauteing. And allow the pressure cooker for one whistle in high flame, and then simmer the flame and cook for 5 minutes.
To Store
This spicy Instant pot marinara sauce is good to use for up to five days when refrigerated and can be used up to two months when frozen. Always use an airtight container for the best results.
The key ingredients
Onion. Onion and tomato are best buddies and never separable. Onion gives a creamy texture and mellow downs the tomato's tartness in this Instant pot marinara sauce. Sweet onion and yellow onion are my favorites when considering the marinara sauce.
Tomato. Ripe plum tomatoes turn this sauce unbelievably rich in color and a chunky texture. Roma tomatoes are the ultimate choice for this spicy marinara sauce recipe(If you don't have Roma tomatoes use plum tomatoes instead).
Basil. Dried basil, helps you maintain the flavor. Fresh basil leaves are also the best choice, but the dried one will not affect the taste though. When adding fresh basil, add then as finely chopped.
Oregano. The rule of basil applies to oregano completely. Use them as dry version or the fresh ones depending on the availability.
Red pepper flakes. This appends the heat and kicks to the sauce. Adjust the quantity to your personal choice. I always lean towards the weather, so I have added one teaspoon. And the heat hit my back of the throat, and I loved the way it is. So, add the red pepper flakes cautiously. Roasted red peppers are also a good substitute for the red pepper flakes.
Olive oil. I would say, olive oil brings out the Italian flavors, and blends the taste of tomato and herbs. If your pantry does not hold this currently, please stock them up before making this marinara sauce.
Diced tomatoes. You may also use the tomato paste, crushed tomato instead.
Red wine is also another classic variations. I have not added here in this recipe, but if you want to use red wine, add to the Instant pot after the garlic and before tomato.

It's so funny that you use the immersion blender to smooth out the sauce. I make homemade sauce and then put it in the blender and puree it so that there isn't a single lump. I'm like a kindergartner lol.
