Amazing 3-Ingredient TOMATO Sauce (and a Little Trick)

Simple 3 Ingredient Tomato Sauce

Welcome to a rich, flavorful 3-ingredient tomato sauce that comes together with almost no effort. This recipe is simple, cozy, and has a little trick that takes it from good to next-level delicious. Spoon it over your fave pasta, zoodles, or enjoy it straight up as a creamy soup.

I’m seriously so excited to share this with you today—because it’s not just any recipe. It’s my friend Esther’s 3-ingredient tomato sauce, and let me tell you… it’s a game changer.

So, here’s how it went down: I made Esther’s sauce for the first time last week, and immediately knew I was in trouble (the good kind). It was so simple, so cozy, and ... I couldn’t stop thinking about it. Like, I had to make it again. ASAP. And yes, I absolutely doubled the batch the first time around because I trust Esther that much (her razzle dazzle herbal iced tea recipe had already won me over).

No regrets. I may or may not have eaten half of this tomato sauce straight from the spoon. (It’s giving major creamy tomato soup vibes, and I am not mad about it.)

I still can’t wrap my head around the fact that this flavor-bomb sauce only needs… wait … three ingredients!? (Not counting salt and pepper, because we’re all seasoning pros here. 😉) And yep, there’s also a tiny little trick that makes these ingredients melt together and transforms this humble tomato sauce into something next-level.

I know you wanna know the secret, so without further ado—here’s Esther’s recipe. You’re welcome.

Text and Recipe by Esther B.

In these times, when many of us are at home and the pantry might be looking rather bare, cooking has taken on a new meaning. Hopefully, you have a few basics on hand to try out this amazing tomato sauce recipe. Although it's very easy, you will be surprised at how good it is.

This is what you will need to do (including the one trick that makes all the difference): Sauté an onion in olive oil, add tomato, and simmer for 10 to 15 minutes. Here comes the trick that makes this tomato sauce sensational: Puree the onions and tomato with a food processor or hand mixer until smooth.

That's it! Using a lot of onions and blending them into the sauce, reduces the sharp, acidic taste of the tomatoes and makes the sauce more balanced and sweet.

Add the sauce to your favorite pasta, zoodles or any other dish that might require a good, homemade tomato sauce. 

Note: You can also sauté a carrot and a rib of celery in with the onions. This gives the sauce an even sweeter and deeper taste, but it is not necessary.
