Along the border, salsa isn’t just something you dip. It’s something you live with. It shows up at breakfast next to eggs, at lunch with tacos, at dinner with carne, and somehow it still ends up on the table again with chips while you’re talking in the kitchen.

Jump to Recipe

In Mexico, salsa roja can be made a few different ways depending on the region and what’s available. Some are raw and blended, some are roasted and smoky, and others are cooked or simmered for a smoother, deeper flavor. This recipe is the homestyle, border-town version: quick-cooked in a covered pan, blended smooth, and ready in 10 minutes. Minimal cutting, big flavor, and it goes with everything, yes, even burgers.

Yield

Makes about 1 cup of salsa (great for 2–4 servings, depending on how generous you are with the chips and everything else you put it on).

1) How spicy is this salsa roja?

With 3 jalapeños and the seeds and veins removed from 1–2, it lands around mild. For more heat, leave more jalapenos intact.

2) Can I use serrano peppers instead of jalapeños?

Yes. Serranos are usually hotter than jalapenos, so start with 1–2 serranos and adjust next time.

Yes. Use your food processor instead of a blender and

4) Why do you cook the ingredients covered?

Covering helps everything soften quickly and helps keep the stove clean.

Chips and salsa is classic, but it’s also amazing on tacos, eggs, burgers, tostadas, and gorditas.
