Charred Serrano and Avocado Dip
A vibrant, smoky dip made by charring serrano peppers directly over flame, then mashing them with ripe avocados, fresh cilantro, and lime juice. The charring brings out deep, complex heat, balanced by creamy avocado and bright citrus. Ready in 10 minutes, it's perfect for chips, vegetables, or as a topping for tacos and grilled meats.
Steps
Before you start
- Choose ripe but not mushy avocados (they should yield slightly to gentle pressure)
- Have all ingredients prepped and ready—the dip comes together very quickly once you start charring
- If you don't have a gas burner, use a dry cast-iron skillet over medium-high heat instead
Char the serrano peppers
- Hold each serrano pepper directly over a gas flame (or place in a dry cast-iron skillet over medium-high heat) and rotate with tongs until the skin is blackened and blistered all over, about 1–2 minutes per side.
- The pepper should be charred but still hold its shape; you're looking for dark brown to black patches covering at least 70% of the surface.

Ready when: Skin is blistered and blackened all over
Tip: Use tongs to hold the pepper—don't touch directly to the flame. Charring slightly blackens the skin, but don't worry about tiny black spots; they add flavor.
Cool and peel the peppers
- Place the charred peppers on a cutting board and let them cool for 1 minute until you can handle them comfortably.
- Using your fingers, gently rub away the charred skin—it should slip off easily.
- Don't rinse them; the charred bits left behind add smoky flavor.
- Remove the stem and shake out most of the seeds (a few remaining seeds are fine for heat).

Ready when: Charred skin comes away easily by rubbing
Tip: Don't rinse the peppers; you'll lose the smoky flavor. The skin should slip off with gentle friction.
Mash avocado with peppers
- Place the peeled charred peppers in a mortar and pestle (or medium bowl) and mash them into a rough paste using the pestle (or fork).
- Add the avocado flesh and continue mashing with a fork or pestle until you reach your desired texture—some prefer it chunky, others prefer it smooth, so mash to your liking (about 10–15 strokes for a slightly chunky texture).

Ready when: Peppers and avocado are mashed to your preferred texture
Tip: Don't over-mash; a few small chunks of avocado add texture. If using a bowl, a fork works fine instead of a mortar and pestle.
Fold in aromatics and season
- Fold in the diced white onion and chopped cilantro using a fork or spoon.
- Squeeze in the lime juice and fold to combine evenly.
- Taste and add kosher salt a pinch at a time until the flavors pop—usually ¼ to ½ teaspoon total, but adjust to your preference.

Ready when: Onion and cilantro are evenly distributed and dip is seasoned to taste
Tip: Taste as you go—the lime juice and salt should bring out the smoky heat of the peppers and the creaminess of the avocado. Don't add salt in one heap; pinch it in gradually.
Serve immediately
- Transfer the dip to a serving bowl.
- Serve right away with tortilla chips, fresh vegetable sticks (jicama, cucumber, bell peppers), or as a topping for tacos, quesadillas, or grilled fish.

Ready when: Dip is ready to eat
Tip: This dip is best served the same day it's made. Avocado browns when exposed to air, so cover with plastic wrap pressing directly onto the surface if you need to store it for a short time.
Good to know
Tips
- For a silkier, more uniform dip, use an immersion blender for 10–15 seconds instead of hand-mashing, but don't overblend—the dip should still have texture.
- If your avocados are slightly firm, let them sit at room temperature for 30 minutes before making the dip. If they're very soft, they'll turn mushy when mashed; choose ones that yield slightly to pressure.
- The charred peppers are the star here—don't skip the charring step or use raw peppers. The heat mellows and the flavor deepens when charred.
- Serve with warm tortilla chips for the best contrast of flavors and textures.
Storage & reheating
Best served immediately. If you must store it, press plastic wrap directly onto the surface to prevent browning and refrigerate for up to 2 hours. Not suitable for freezing.
Substitutions
- fresh serrano peppers → jalapeño peppers (3–4 medium) or Thai chilies. Jalapeños are milder; Thai chilies are much spicier. Char them the same way. You can also use pre-roasted poblano peppers if you can't char fresh peppers.
- white onion → red onion or shallot, finely diced. Red onion adds sweetness and color; shallot adds a more delicate onion flavor. Use the same amount.
- fresh cilantro leaves → fresh parsley or a mix of cilantro and mint. Parsley is milder; mint adds brightness. Use the same amount. Cilantro is traditional, so omit entirely if you dislike it rather than substituting.
- fresh lime juice → lemon juice or white vinegar. Lemon gives a slightly less bright acidity; vinegar is sharper. Start with 1½ tablespoons and taste, adding more if needed.
