Ingredients
• 4 vine-ripened tomatoes, quartered
• 2 cloves garlic, halved
• 2 small serrano peppers, stemmed and halved lengthwise
• 1 small onion, cut into large chunks
• 3 tablespoons / 45 ml (1.5 fl oz) avocado oil or olive oil
• 2 teaspoons / 10 g (0.35 oz) sea salt, divided
• ¼ cup / 15 g (0.53 oz) loosely packed fresh cilantro leaves
• Juice of ½ lime, or more to taste
• ½ teaspoon / 1 g (0.04 oz) ground cumin
• For Serving (Optional)
• Sliced bell peppers
• Sliced cucumbers
• Pork rinds
• Low-carb crackers
Instructions
1. Directions
2. Position an oven rack in the top third of the oven and preheat to broil on high.
3. On a rimmed baking sheet, combine the quartered tomatoes, halved garlic, serrano peppers, and onion chunks. Drizzle with oil and sprinkle with 1 teaspoon (5 ml / 0.2 fl oz) of sea salt. Toss well to coat everything evenly, then spread into a single layer.
4. Broil on the top rack for about 10 minutes, or until the vegetables are softened and nicely charred in spots.
5. Carefully transfer the entire contents of the baking sheet, including any juices, to a food processor or high-powered blender. Add the fresh cilantro, lime juice, ground cumin, and the remaining 1 teaspoon (5 ml / 0.2 fl oz) of sea salt.
6. Pulse the mixture until it reaches your desired consistency—mostly smooth but with a little bit of texture is ideal. Taste and adjust with more lime juice or salt if needed.
7. Serve immediately or, for best results, chill for a few hours to let the flavors meld. Store any leftovers in an airtight container in the refrigerator for up to one week.

Pro Tips
• Control the Heat: Serrano peppers vary in spiciness. Add them to the blender one at a time, pulsing and tasting as you go, to achieve your perfect heat level.
• Let It Mingle: For the absolute best flavor, let the salsa chill in the refrigerator for at least an hour before serving. This allows all the smoky, spicy, and tangy notes to meld together perfectly.
• Don’t Waste the Juices: When transferring the roasted vegetables to the blender, be sure to scrape in all the delicious, concentrated juices from the bottom of the baking sheet. That’s where a ton of flavor lives!
• Quick Canned Shortcut: In a pinch, skip the broiling. Use one 28-ounce can of fire-roasted tomatoes and one 14.5-ounce can of diced tomatoes with green chiles. Drain them well before blending with the other .

Pro Tips
- Broil everything on the top rack in a single layer until the vegetables are softened and charred in spots, then scrape every drop of the pan juices into the blender — that's where the concentrated flavor lives.
- Add the serrano peppers to the blender one at a time, pulsing and tasting between each, since their heat level varies from pepper to pepper.
- Pulse rather than puree: aim for mostly smooth with a little texture, the way restaurant salsa is served.
- Let the finished salsa chill in the refrigerator for at least an hour so the smoky, spicy, and tangy notes have time to meld before serving.
- For a shortcut, drain two cans — one 28-ounce fire-roasted tomatoes and one 14.5-ounce diced tomatoes with green chiles — and blend with the same aromatics instead of broiling.
Frequently Asked Questions
Can I make this salsa ahead of time?
Yes, and you should — it tastes best after chilling for at least an hour so the flavors meld. Leftovers keep in an airtight container in the refrigerator for up to one week.

That depends on your serranos. Start by blending one pepper, taste, and add the second only if you want more heat — it's the easiest way to land at your perfect spice level.
