To roast the poblanos, turn the flame on a gas stovetop on high and place the poblano peppers on the grates. Using tongs, flip the peppers every so often until the outside has charred on all sides. Afterward, place in a bowl, seal it well with plastic wrap, and let the steam do its job. After about 30 minutes, you’ll be able to peel the skin off the outside and reveal a beautifully roasted poblano pepper that you can de-seed, cut up, and use!
3 poblano peppers
In a medium saucepan, melt butter on medium heat. Once melted, add onion and garlic and cook for 3–5 minutes or until translucent.
