Ingredients
- olive oil: brings everything together and helps the vegetables roast up golden Look for olive oil that tastes fresh and grassy if possible
- onion: adds aromatic sweetness to balance the mild heat of the peppers Grab a firm onion with shiny skin
- poblano peppers: the star of the show Imparts a deep green flavor that is just the right amount of earthy and mild Check for glossy skin and avoid any with big soft spots
- butter: gives the sauce richness Use real butter for creaminess
- flour: helps achieve the proper thickness Opt for unbleached all purpose flour for best results
- chicken broth: brings a savory undercurrent Choose a broth with clean ingredients for maximum flavor
- sour cream: the secret to silky texture Go for full fat sour cream for the best luscious mouthfeel
- garlic: gives gentle warmth and a classic Mexican profile Pick heads of garlic that feel heavy and firm
- cumin: this spice rounds out everything with a hint of earthiness Toasted cumin makes it extra pungent
- salt: brings out the best in each ingredient Kosher salt dissolves evenly throughout the sauce

Step-by-Step Instructions
- Preheat and Roast:
- Set your oven to 375 degrees Slice the poblanos in half and scoop out the seeds and membranes Roughly chop the onion Combine poblano halves and onions on a baking sheet Drizzle with olive oil sprinkle with a bit of salt and pepper Toss gently to coat everything in oil Place poblanos skin side up so they char properly Roast until the peppers are blistered and onions are caramelized about half an hour
- Steam and Peel:
- Transfer the hot roasted peppers into a bowl and cover tightly with plastic wrap or move them into a plastic bag Seal and let them steam for about ten minutes This makes the tough skins loosen Once cool enough handle the peppers gently and peel off the skins Discard the skins you want the flesh only
- Make a Roux:
- Set a skillet over medium high heat Add the butter and let it melt Once melted sprinkle in the flour Whisk continuously until you have a thick smooth mixture Cook this for three to four minutes until it smells nutty and just starts to turn pale brown
- Thicken Sauce:
- Slowly pour in chicken broth while whisking This helps prevent lumps Let this mixture simmer gently for five to ten minutes until it thickens to the consistency of gravy
- Blend It All:
- In a blender or food processor add the creamy roux the peeled roasted poblanos caramelized onion sour cream garlic cumin and salt Blend on high until completely smooth Taste the sauce and add extra salt and pepper if desired I like to blend for a minute to get an ultra velvety finish

I will always remember the first time my nephew dunked a roasted potato wedge into this sauce at Sunday lunch and gleefully declared it his new favorite snack Poblanos have become an unofficial mascot for family meals since then

Poblano cream sauce will stay fresh in a sealed container in the fridge for up to four days Let it cool completely before storing for maximum freshness If reheating stir gently over low heat on the stovetop to maintain the creamy texture You can also freeze it in small portions just whisk well after thawing to bring it back together
Ingredient Substitutions
You can swap the chicken broth for vegetable broth if you want a vegetarian version For extra richness try adding a splash of heavy cream with the sour cream If poblano peppers are hard to find mild green bell peppers with a little canned green chile make a fair stand in though the smoky depth will be less pronounced
