Ingredients
Method
- Preheat your oven to 400°F and line a baking sheet with parchment or foil for easy cleanup.
- Remove the papery husks from the tomatillos—they should come off easily—and rinse them thoroughly under cold water to wash away the sticky residue. Pat dry with a towel.
- Halve each tomatillo, then place them cut-side down on your prepared baking sheet along with the serrano chiles (leave whole or halve if you prefer less heat). Scatter the garlic cloves and onion halves among them—don't worry about peeling the onion, that's where the best flavor concentrates anyway.
- Drizzle everything generously with olive oil and sprinkle with kosher salt. Toss gently to coat evenly, then spread into a single layer so all surfaces get exposed to the heat.
- Roast for 20-25 minutes until the edges are golden-brown and slightly charred. The tomatillos should be tender when pressed with a fork. Remove from the oven and let cool for about 5 minutes.
- Once cool enough to handle, peel the onion halves (they'll slip out of their skins easily). Transfer everything—the roasted tomatoes, chiles, garlic, and onion—to a food processor or blender.
- Pulse until you reach your desired consistency: chunky works well if you like texture, smooth for something more uniform. Taste and adjust seasoning with additional salt as needed.
- Transfer to a bowl, garnish with fresh cilantro, and serve immediately with tortilla chips, tacos, grilled meats, or just about anything else that calls for green salsa.

Notes
What keeps pulling me back is how the roasting transforms the tangy green into something richer without losing that bright edge. I learned early on to keep the husks on while peeling and let the tomatoes sit in a hot pan with olive oil before they hit the oven—that little bit of sear makes all the difference.
I keep this on hand because it's versatile enough for tacos, bowls, or just slapping onto a tortilla. One practical note: if you're using store-bought tomatillos that look very green and firm, roast them an extra five minutes so they soften properly. The skin will blister but shouldn't blacken.
