I make this easy poblano sauce whenever I want something creamy, smoky, and bright that pairs with almost anything—grain bowls, tacos, roasted vegetables, or simply as a dip. The cashews give it a silky texture, lime adds a lively citrus lift, and roasted poblanos bring deep, charred flavor. I’ve mixed in avocado for a nut-free version and added jalapeño when I want heat; it’s versatile and reliably delicious.

Smoky, spicy sauce you can spoon on anything
I developed this poblano sauce after a visit to Oaxaca, where green sauces of all kinds accompanied nearly every meal—herbal, tangy, spicy, and creamy. One sauce I tasted with roasted squash lingered in my mind for its smooth richness and gentle heat. Back home I experimented with roasted poblanos, garlic, and cashews until this balanced, easy version emerged. It’s become a go-to fridge staple.
This sauce is intentionally flexible. Use avocado in place of cashews for a nut-free option, add a jalapeño for heat, or thin it with water for a dressing. The essential step is roasting the poblanos until their skins are blistered and blackened to develop that unmistakable smoky depth. A quick blend finishes it—store it in the fridge and it often tastes even better the next day.
Ingredients and why they matter
With only a few ingredients, quality and freshness make a difference. You’ll need poblanos for their mild, smoky character; garlic for savory depth; lime or lemon juice for acidity; raw cashews to create a creamy body; and water to help blend everything smoothly.
Full ingredient list and detailed instructions are in the recipe card below.
Notes & Variations
- Poblano peppers: Roast until well-blistered for the best smoky, earthy flavor. Removing the skins yields a smoother sauce.
- Cashews: Soaking softens them for a silky texture. Substitute avocado for a nut-free alternative.
- Garlic: Roasted garlic mellows and sweetens; raw garlic will overpower the sauce.
- Lime juice + zest: Adds acidity and brightness to cut through the richness; lime pairs especially well with the smoky notes.
- Jalapeño (optional): Add for extra heat; include seeds if you prefer it spicier.
TIPS & TRICKS
Shruthi’s top tips
- Blacken the poblanos fully. Under-roasting produces a milder, less interesting sauce.
- Steam before peeling. Cover roasted peppers for a few minutes to loosen skins for easy removal.
- Soak cashews with lime juice and water before blending for extra flavor and smoothness.
- Use a high-speed or smoothie setting on your blender to get a silky finish.
- Add water slowly while blending to control thickness—this determines whether it’s a dip or a pourable sauce.
How to make poblano cream sauce
Step 1:
Place cashews, water, and lime juice in a blender and let them soak for a few minutes. Don’t blend yet.
Step 2:
Preheat the oven to 425°F (218°C). Arrange poblano peppers on a baking sheet and wrap garlic cloves in foil; place the garlic on the same sheet. Roast 15–20 minutes, turning peppers halfway so they char evenly.
Step 3:
Transfer roasted peppers to a bowl, cover (or use a zip-top bag) and let steam for a few minutes to loosen the skins. Remove stems, peel off charred skin if desired, and scoop out the seeds.
Step 4:
Add the roasted garlic and peeled poblanos to the blender with the soaked cashews. Blend on high (smoothie setting if available) for 3–5 minutes until completely smooth. Add water in small increments to reach your preferred consistency and season with salt to taste.
Step 5:
Serve immediately as a dip, spread, or sauce for tacos, enchiladas, grain bowls, roasted vegetables, or chips.
How to serve poblano sauce
Spoon the roasted poblano sauce over black bean tacos, veggie quesadillas, roasted vegetable salads, elotes, or use it as a dip for tortilla chips. It adds a creamy, smoky lift to virtually any savory dish.
Storage and reheating suggestions
Store the sauce in an airtight container in the refrigerator for up to 5 days; give it a quick stir before serving. You can also freeze the sauce for up to 2 months—thaw overnight in the fridge and blend briefly to refresh the texture if needed.

Easy Poblano Sauce
Equipment
-
Blender
Ingredients
- 3 poblano peppers
- 3 garlic cloves
- 1 cup raw cashews unsalted/unroasted (or substitute 1–2 ripe avocados)

- 1 jalapeño optional for spice
Instructions
-
Place cashews, water, and lime juice in a blender and let them soak for a few minutes.
-
Preheat oven to 425°F (218°C). Place poblanos on a baking sheet. Wrap garlic cloves in foil and roast for 15–20 minutes, turning peppers halfway so the skin blackens and blisters. If using a gas flame or grill, carefully char peppers directly over the flame until fully blistered.
-
Transfer peppers to a bowl, cover to steam for a few minutes, then remove stems, peel skins if desired, and discard seeds.
-
Add roasted garlic and peeled poblanos to the blender with the soaked cashews and blend on high until smooth. Add water gradually to adjust consistency and season with salt to taste.
-
Serve immediately as a dip, spread, or sauce. Store in an airtight container in the fridge for up to 5 days.
Notes
- For a nut-free version, use 1–2 ripe avocados instead of cashews and water.
- Add a jalapeño or serrano pepper for more heat; the base recipe is mild.
- To thin the sauce for dressings or drizzling, add water a little at a time until you reach the desired consistency.
