Marinara vs tomato sauce

Are you wondering about the difference between this tomato sauce and marinara sauce? Both are great over pasta, however, marinara is more of a fresh and quick sauce made with just a handful of ingredients, while tomato sauce is a slow-cooked, complex dish that allows tomatoes and seasonings to develop richer flavor and darker color. Mariana – fresh and quick, tomato sauce – rich and slow-cooked. 


The reason we love making tomato sauce in Instant Pot is that it takes half the time. If you were to slow-cook this sauce on the stove, it would need about 1 hour. The Instant Pot takes 30 minutes (with pressure build-up and release) and pressure cooking really locks in all those nutrients. 

To make this recipe, you will need an emersion blender (stick) to puree the soup inside the pot once it’s ready. Alternatively, you can blend the sauce in a food processor or a blender in batches once it has cooled down slightly. Here is a handy video on how to make this tomato sauce. You will find a full list of ingredients, instructions and nutrition breakdown below.

  1. I love my pressure cooker, but I’ve been making a 10-veg sauce based on Otamot ingredients for a while now, and I roast it in the oven. I call it V10 . I start at 400° and in a while turn it down to 350°. It’s usually a huge pan full of vegs., so it takes a couple hours (& smells heavenly).

    I think this is one “recipe” (not exactly a recipe!) that benefits in flavor from the oven. It’s more time consuming, but the time is basically hands-off. And oh, my gosh, the flavor is wonderful (& a little sweet, as you mentioned), Not to deter anyone from going the pressure cooker route, still a terrific sauce either way, and full of nutrition. Just an additional way to do it.

  2. Just a comment. Mushrooms are Not vegetables. They’re often in vegetable broth. I’m only mentioning it because my sister is allergic to mushrooms and never thought to check vegetable broth for mushrooms. She’s gotten mad at restaurants after getting sick from eating at them when they told her there were no mushrooms in the food.

  3. I haven’t made it yet, but I’m going to. You suggested using pumpkin instead of carrots. Canned pumpkin? If so, what quantity would you suggest? Whole pumpkin? If so, suggested quantity? Ty!

    1. About 2-3 cups of diced raw pumpkin but if you want to use canned pumpkin, just add a can or a cup if you like, more or less won’t ruin the sauce but will add more or less sweetness

  4. I made this with some tweaks to the veggies and used what I had but it’s delish! I’m hiding veggies in plain site! Love it!!!

      1. Sounds delicious, I’ll definitely try it.

        I was wondering, if you could substitute the canned tomatoes with fresh tomatoes?

        1. Yes, you could chop up fresh tomatoes and the juice you yield from them. Can’t tell you exactly how many you would need so I would weight them once they are chopped.

  5. Super easy, tasty, easy to customize. Don’t like Garlic? leave it out. Love Onions? double the amount. Kids will eat this enthusiastically. I’ve actually even modified this to make a Moroccan stew base. This recipe is a keeper/winner.
    Note though: “Immersion’ blender not “emersion”
