Poblano Cream Sauce Recipe
This poblano cream sauce is rich, smoky, and just the right amount of spicy, made with roasted poblanos, fresh lime juice, and creamy sour cream or crema. It’s the perfect finishing sauce for grilled meats, tacos, or roasted vegetables, adding bold flavor with a smooth, velvety texture.
If you are looking for a bold, smoky, creamy poblano sauce that works on just about everything, this grilled poblano cream sauce recipe is it. Poblano peppers go straight onto the grill until the skins are charred and blistered, then get blended with sour cream, garlic cloves, lime juice, and cilantro into a creamy sauce you will want to put on chicken, steak, shrimp, tacos, and more. It comes together in about 20 minutes and keeps well in the fridge all week.
Why This Recipe Works
- The grill adds depth you cannot fake. Charring the poblano peppers directly on the grill grates creates a smoky, slightly sweet flavor that oven broiling alone just does not replicate. That char is what makes this sauce taste like something you ordered at a restaurant.
- Sour cream gives it body without cooking. Unlike a pan sauce that requires reducing cream over medium heat, this blender method is faster and produces a thick, pourable consistency that clings to whatever you put it on.
- Poblanos are the right pepper for this. They are mild enough to let the smoky, earthy flavor come through without blowing out your palate, and they blend into a smooth, vibrant flavor-packed green sauce with almost no effort.
- One recipe, endless uses. This sauce works as a drizzle, a dip, a taco topping, and a protein sauce all at once. I used it on this reverse-seared tomahawk steak (pictured).
Ingredients
Find everything you need in the complete recipe card below – here is a brief overview of what you will need and substitutions!
Poblano Cream Sauce
- Large poblano peppers
- Jalapeno (seeds optional – so it adds flavor but less spice)
- Yellow Onion
- Full-fat sour cream (or Mexican crema)
- Fresh lime juice
- Fresh cilantro
- Kosher salt
- Water
Substitutions: Swap sour cream for Mexican crema (also sold as crema mexicana at most grocery stores) if you want a slightly thinner, less tangy sauce. No fresh cilantro? Flat-leaf parsley works in a pinch, though the flavor will be more herby and less bright. Greek yogurt can replace the sour cream for a tangier, higher-protein version, though the sauce will be a bit thicker. For extra savory depth, a splash of chicken broth or vegetable stock can be added to the blender to thin the sauce and round out the flavor. For a dairy-free version, full-fat coconut cream can replace the sour cream, though the flavor profile will shift.
How to Make Grilled Poblano Cream Sauce
Prep and Grill the Poblanos
Preheat your gas grill to high heat, around 450 to 500 degrees F. Rub the large poblano peppers all over with a thin coat of vegetable oil. Place them directly on the grill grates and close the lid. Grill for about 3 to 4 minutes per side, turning every few minutes, until the charred skin is deeply blistered on all sides. Total grill time is roughly 10 to 12 minutes. If using charcoal, you can also put the peppers directly onto the coals.
No grill? You can get the same charred skin by holding the peppers over the flame of a gas stove using tongs, rotating until blistered all over, or under the broiler on a baking sheet.
Once charred, transfer the peppers to a bowl or plastic bag. Let them steam for 5 to 10 minutes. This is what makes the skins slip off cleanly.
Peel and Prep the Peppers
After steaming, peel the charred skin off the peppers. They should release easily. Use paper towels to help grip the skins if needed — some cooks call this the paper towel peel method. Remove the stems and open each pepper to scrape out the seeds and membranes. For a low heat level, remove all seeds. If you want a little heat, leave some in.
Do not rinse the peppers under water to remove any leftover charred skin. You will wash away the smoky flavor you just built on the grill.
Blend the Sauce
Add the peeled, seeded poblano peppers to a blender or food processor along with the sour cream, garlic cloves, lime juice, cilantro, and a pinch of salt. Blend on high until you reach a smooth, velvety texture, about 30 to 60 seconds. A blender will give you the silkiest result; a food processor gives a slightly chunkier, more rustic consistency.
Taste test as you go. Adjust salt and lime juice as needed. If the sauce is thicker than you want, add a cup of water one tablespoon at a time and blend again to reach the right consistency.
Tips and Variations
Make it ahead. This creamy sauce actually tastes better the next day once the flavors have melded. Store it in an airtight container in the fridge for up to 5 days.
Control the consistency. For a thick dip, use full-fat sour cream and blend briefly. For a thinner drizzle, use Mexican crema or add water a tablespoon at a time until you hit the right consistency.
Adjust the heat level. Poblano peppers are a mild pepper, typically 1,000 to 2,000 Scoville units — much lower than a jalapeño. If you want more heat, add half a seeded jalapeño to the blender. Want it milder? Add an extra spoonful of sour cream.
Low carb and keto-friendly. This sauce is naturally low-carb. With full-fat sour cream as the base, it fits well into a keto eating plan. One serving (about 2 tablespoons) runs roughly 2 to 3 grams of net carbs, depending on your sour cream brand.
Add green onions. A few chopped green onions blended in add a mild onion bite and deepen the green color of the sauce. It is one of my favorite ways to customize this recipe.
What to serve it on: Grilled and smoked chicken thighs, smoked tomahawk steaks, smoked shrimp, fish tacos, burrito bowls, nachos, scrambled eggs, roasted cauliflower steaks, and your favorite tacos. It also doubles as a dip — way more interesting than the usual options.
Frequently Asked Questions
Not very. Poblano peppers are one of the milder chiles, sitting well below jalapeños on the heat scale. The sauce has a gentle warmth and earthy flavor, but it is not a spicy food situation by any stretch. Removing all seeds and membranes before blending keeps the heat level very mild.
They are used interchangeably, but poblano crema typically refers to a thinner, pourable sauce made with Mexican crema as the base. Cream sauce versions using sour cream tend to be thicker and slightly tangier. Both start with roasted or charred poblano peppers.
Most large grocery stores carry fresh poblano peppers year-round in the produce section, usually near other specialty peppers. Look for large, dark green peppers about the size of your hand. They are often stocked near bell peppers and Anaheim chiles.
A food processor works well and produces a slightly chunkier texture, which is great if you want more body in the sauce. A blender gives you the smoothest, most velvety result.
Stored in an airtight container, it keeps for 4 to 5 days. Stir it before serving since the sour cream can separate slightly after sitting.
Freezing is not recommended. Dairy-based sauces tend to separate when frozen and thawed, which affects both texture and appearance. This is an easy recipe to make fresh as needed.
