⭐ Why I Love This Recipe
I first made this sauce on a random weeknight when I had leftover poblanos from taco night. I threw them in the oven and whipped this up—and now it’s a regular thing in my kitchen. Here’s why I keep coming back to it:
- It’s done in 30 minutes or less.
- It goes with just about everything.
- You can make it ahead and store it.
- It feels fancy, but it’s actually super easy.
- It makes even leftovers taste brand new.

👩🔬 Why This Recipe Works (Quick Science

⚠️ Common Mistakes
- Not roasting the peppers enough – You want them blistered and blackened to get that smoky flavor.

- Too much lime – A little goes a long way. Start small, taste, then add more.
- Using cold sour cream – Let it come to room temp to blend better and avoid curdling.

Poblanos are mild! The sauce is flavorful, not hot. If you want it spicier, toss in a jalapeño.
Can I use a food processor instead of a blender?
Yep! Just make sure everything gets really smooth.
