Ingredients You’ll Need

This sauce comes together with just a handful of kitchen staples, but each ingredient has a vital role to play. From the mellow heat of poblanos to the silky finish from a splash of sour cream, you’ll see just how much character goes into every spoonful.

• Poblano peppers: These mild green chilies provide the signature smokiness and body for the sauce—be sure to roast them for the best flavor.
• Olive oil: Helps the peppers and onions caramelize and roast to perfection with a gorgeous golden sheen.
• Onion: Adds aromatic sweetness, balancing the earthy quality of the poblanos.
• Butter: Brings a luscious, classic cream sauce richness you’ll love.
• Flour: Used to make a quick roux, this thickens the sauce for a silky, coat-everything texture.
• Chicken broth: Lends another dimension of flavor, providing just enough body and savoriness.
• Sour cream: The secret weapon for tang and creaminess that ties it all together.
• Garlic: Two cloves add aromatic depth and elevate the roasted flavors.
• Cumin: Just a hint adds warmth and quietly echoes the smokiness in the peppers.
• Salt: Essential for brightening every ingredient—taste as you go for the perfect balance.
• Salt and pepper (to taste): Gives you the reigns for seasoning, so your Poblano Cream Sauce sings for your palate.

How to Make Poblano Cream Sauce

Step 1: Roast the Poblanos and Onions

Begin by preheating your oven to 375 degrees. Slice the poblano peppers in half lengthwise and remove the seeds and membranes inside. Spread the poblanos and rough-chopped onions on a baking sheet, then drizzle with olive oil and give them a good toss with a pinch of salt and pepper. Arrange the peppers skin side up so they can properly blister and roast for 30 minutes. This roasting step transforms the raw ingredients into a rich, smoky flavor base that defines a great Poblano Cream Sauce.

Step 2: Steam and Peel the Peppers

Once the peppers and onions are roasted, immediately transfer the hot peppers to a bowl and cover it tightly with plastic wrap, or slip them into a plastic bag. Let them steam for around 10 minutes—this little trick loosens the papery skins, making them a breeze to peel away. When the peppers are cool enough to handle, peel off and discard the skins so all you’re left with is luscious, roasted flesh. This step is key for the silkiest sauce texture.

Step 3: Make the Roux

While the peppers are steaming, set a medium skillet over medium-high heat and melt the butter until it’s bubbling but not browned. Sprinkle in the flour and start whisking to combine into a thick, smooth paste; this is your roux. Let the roux bubble for a few minutes, whisking constantly, until it’s lightly golden and the raw flour taste is gone—this is what will give your Poblano Cream Sauce its tender, creamy richness.

Step 4: Add Chicken Broth and Thicken

Slowly pour in the chicken broth, whisking the whole time to avoid lumps and to ensure the sauce base stays silky. Continue to cook for 5–10 minutes until the mixture has thickened slightly. This forms the backbone of your sauce, building a velvety consistency that will hug every roasted pepper you blend in.

Step 5: Blend it All Together

Transfer the thickened sauce base to a blender or food processor. Add the peeled roasted poblanos, roasted onions, sour cream, garlic cloves, cumin, and salt. Pulse and blend until the sauce is ultra-smooth and creamy, pausing to scrape down the sides as needed. Taste it! Add extra salt and pepper if you like; this step lets you dial in that perfect harmony that makes homemade Poblano Cream Sauce shine. Pour into a serving bowl and it’s ready for absolutely everything.

How to Serve Poblano Cream Sauce

Garnishes

A final flourish goes a long way, and there are so many ways to make your Poblano Cream Sauce feel truly special. I love a scatter of chopped cilantro, a pinch of smoked paprika, or a sprinkle of cotija cheese over the top. Even a wedge of lime on the side lets each person tailor that pop of bright flavor to their taste. Whether you dress it up or keep it classic, that pop of green color always looks inviting.

Side Dishes

This creamy, dreamy sauce is delicious draped over grilled chicken, fish, or steak, but don’t stop there—try it as a dip for roasted potatoes, spooned over rice or quinoa, or even as a base for roasted vegetable bowls. It pairs beautifully with street corn, crispy tortilla chips, or alongside a big skillet of fajitas. The possibilities are as bold as the sauce itself.

Creative Ways to Present

For a little wow-factor, serve Poblano Cream Sauce in a small pitcher or pour-over jug at the table, letting guests drizzle as they please. It also makes an eye-catching drizzle over tacos, enchiladas, or baked potatoes. For a playful touch, swirl it onto plates before layering on grilled proteins, or serve in mini cups for a tasting platter at your next gathering.

Make Ahead and Storage

Storing Leftovers

If you happen to have leftover Poblano Cream Sauce (lucky you!), store it in an airtight container in the refrigerator. It keeps well for up to 4 days, and I swear the flavors get even cozier after a day or two—ideal for meal prep.

Freezing

For longer storage, you can absolutely freeze your sauce. Pour the cooled Poblano Cream Sauce into small airtight containers or even ice cube trays for easy portioning. Freeze for up to 2 months. Thaw overnight in the fridge before reheating, and give it a good stir to restore its creamy smoothness.

Reheating

Reheating is a breeze—just warm the sauce gently in a saucepan over low heat, whisking often. If it seems too thick, whisk in a splash of broth or milk until you get your desired consistency. Take care not to boil; gentle heat is the secret to preserving that lovely texture.

FAQs

Can I use another type of pepper instead of poblano?

Absolutely! If poblanos are hard to find, you can substitute Anaheim or bell peppers for a milder sauce, or even hatch chilies for a more assertive flavor. Keep in mind that swapping peppers will change the heat and taste profile, but your sauce will still be delicious.

Is this Poblano Cream Sauce spicy?

Generally, poblano peppers are quite mild, so the sauce has a gentle warmth rather than searing heat. If you prefer it spicier, you can leave in a few pepper seeds, or toss in a jalapeño during blending to turn up the heat.

Can I make it dairy-free?

Yes, you can adapt this recipe for a dairy-free version! Use olive oil instead of butter for the roux, swap in a plant-based sour cream, and use any non-dairy milk or broth to achieve the right consistency. The sauce will still be rich and flavorful, perfect for all your dairy-free friends.

What if I don’t have a blender?

No worries! An immersion blender works well if you blend the sauce directly in the pot. If you don’t have either, simply chop the roasted peppers and onions as finely as possible and whisk them into the cream sauce—the texture will be a bit rustic, but the flavor is all there.

How can I use leftover Poblano Cream Sauce?

Leftovers are a gift! Drizzle it onto scrambled eggs, stir into pasta, spoon over baked potatoes, or use as a dip for fresh veggies. You can even thin it out with broth and serve as a unique, creamy soup starter.
