I’ve done it. I’ve perfected it.
A simple, addictive salsa just like what they give me at my favorite Mexican restaurant. The kind you scarf down like it’s a race to the bottom of the bowl, with bottomless hot crispy tortilla chips. And then…. they bring you another helping.
When I ask for a to-go box and a container for the rest of the salsa at my go-to Mexican place (Los Reyes in Charleston, SC, by the way), sometimes they give me extra salsa in a BIG CUP to take home. It’s like winning the freaking lottery.
But now? I can have it… whenever. I. want.
Yeah, queso’s good too, but having a signature homemade salsa is essential. Do yourself a favor and try this one out!! Serve it with my favorite flank steak tacos for a delicious restaurant-style meal!

Ingredients
Why canned tomatoes?
I tested this recipe both with fresh Roma tomatoes and canned whole tomatoes. Both were delicious but I didn’t feel like I really nailed the recipe until I switched to canned.
Here’s why I recommend using canned tomatoes to make this blender salsa:
- Canned tomatoes are always in season. That means your salsa is consistent year-round.
- Tomatoes are canned at the peak of freshness and have added salt that enhances their tomatoey flavor.
- Canned tomatoes are bright red, making the salsa bright red. My salsa always ended up pink when I was using fresh. (That may be different if you use fresh tomatoes that are absolutely at peak season, like in July or August.)
- They’re peeled. You won’t have to peel your tomatoes or end up with weird bits of tomato skin in your salsa.
- You can keep a couple cans in your pantry for salsa emergencies.
- Even Bon Appetit agrees that canned tomatoes are preferable to fresh in most uses.

How to make restaurant-style salsa
You’ll find a lot of recipes out there that take 5-10 minutes total, but after repeated testing I’m confident that spending the extra time to roast your veggies is 100% worth it.
My un-roasted salsas had too much of a fresh pico de gallo flavor, which isn’t what I wanted or what I get at my favorite restaurant. Roasting the veggies mellows them, giving a more unified, less sharp flavor to your salsa.
This recipe takes about 30 minutes total with only 10 minutes of hands on time.
For details and full instructions, see the recipe card at the bottom of the post.

Step 1. Cut the veggies.
Julienne your onion, halve the jalapeños, and cut the tips off the garlic cloves. This only takes a minute.
Step 2. Roast the veggies.
Drizzle with olive oil and roast for 20 minutes.
Step 3. Blend it.
Blend the roasted onion and garlic with the tomatoes and salt. Add and blend jalapeño to taste, 1/2 a pepper at a time. See my tips and tricks for details! Enjoy!

Tips & Tricks for The Best Blender Salsa
How many jalapeños do I need?
Jalapeño peppers can vary tremendously in their heat level, anywhere from 2,000 to 8,000 Scoville heat units depending on the specific pepper. Most of the heat is in the seeds and pith, so remove them if you like a mild salsa.
My top tip? Roast more jalapeños than you think you need.
For mild salsa:
Roast 2 jalapeños.
Use 1/2 to 1-1/2 peppers, seeds and pith removed.
Start with 1/2 pepper, and add 1/2 at a time as needed. Add seeds and pith back as necessary for additional heat.
For medium to hot salsa:
Roast 3 jalapeños.
Use 1-3 peppers, with seeds and pith.
Start with 1/2 pepper, and add 1/2 at a time as needed.
Got extra roasted jalapeños? Freeze them for your next batch!
Using fresh tomatoes?
- When to use fresh tomatoes: Only use fresh tomatoes (Roma or plum tomatoes) for this recipe if they’re at peak season (July/August) or if you have an abundance you need to use up.
- Roast them along with the other veggies. The skin will peel off easily after they cool, or you can throw them in the blender skin and all.
- Salsa is pink? That’s common if you’re using fresh tomatoes. It won’t look as bright red as using canned tomatoes but your salsa will still be deeelicious!
More tips
- Don’t skimp on the salt. I added more salt than I anticipated to this salsa, comparing back and forth between the salsa I took home from the restaurant. Although canned tomatoes are already salted, I added an additional 1 to 1 1/2 teaspoons of kosher salt to make the perfect salsa. It made a huge difference when I hit the right amount.
- Refrigerating is worth it. Look, I won’t judge if you can’t keep your chips out of the salsa till tomorrow. But a night in the fridge really helps unify the flavors.
- My favorite chips to have with this salsa are the Cantina Style Tostitos! I thought I was over Tostitos until I discovered these! They’re light, crisp, and airy, and are just perfect with this salsa.

Restaurant-style Tomato-Jalapeño Blender Salsa Recipe
Equipment
Ingredients
- ½ medium onion white or yellow
- 4 cloves garlic unpeeled, tops sliced off
- 2-3 jalapeño peppers
- 1 tablespoon olive oil
- 28 oz canned whole tomatoes
- 1 teaspoon kosher salt
Instructions
Prepare and roast veggies
- Preheat oven or toaster oven to 400 degrees F.
- Cut onion in half, peel, and remove core. Julienne or cut into 4-8 wedges.
- Slice the tops off unpeeled garlic cloves. Leave them together in a clump if you can.
- Cut the stem off the jalapeño peppers and slice in half lengthwise.
- Arrange veggies on a baking sheet and drizzle with olive oil, making sure some gets on the cut ends of the garlic. Toss slightly to coat. Roast for 20 minutes and remove to cool.
Blend the salsa.
- Drain the tomatoes, reserving the liquid.
- Squeeze the roasted garlic cloves out of their peels. Add garlic, onion, tomatoes, and salt to a blender.
- Start by adding ½ a jalapeño pepper to the blender, removing the seeds and pith if you like a more mild salsa. Blend until it reaches your desired consistency, scraping down the sides as necessary. If it has a hard time blending you can add a tablespoon of the reserved tomato liquid, but be sparing or your salsa will be watery.
- Taste the salsa and add more jalapeño or salt if desired. I usually add 1-2 jalapeños for a medium to hot salsa, depending on how hot my specific peppers are. Sometimes they're super mild though and I could add up to 3.
- Enjoy with your favorite tortilla chips or on a taco!
