Comfort food meets bright, smoky Southwestern flavor in this creamy, crowd-pleasing Poblano Macaroni and Cheese. Think silky white cheddar sauce studded with charred poblano, a hint of lime zest for brightness, and a sprinkle of crumbly Cotija to finish. This is the kind of macaroni and cheese that wants to be on your weeknight table but is elegant enough for weekend guests. The recipe is straightforward, pantry-forward, and balanced—peppery, cheesy, and just tangy enough to cut through the richness.

Why this version works

Traditional macaroni and cheese is beloved for its simplicity. Here, roasted poblano chiles introduce a gentle smoke and vegetal sweetness that complements white cheddar perfectly. Mustard powder and cumin lend a subtle savory backbone, while a dash of cayenne brings a whisper of heat. Lime zest and chopped cilantro lift the sauce, creating contrast and a brighter finish. The Cotija adds a crumbly, salty texture that plays beautifully against the creamy sauce.

Flavor tips and swaps

If you prefer less heat, remove seeds and membranes from the roasted poblanos before chopping. For extra smoke, char the peppers over an open flame or under a broiler until blackened. If you want a creamier texture, stir in an extra tablespoon of butter or a splash of cream with the milk. If Cotija isn’t available, use a crumbly feta-style cheese with a mild tang.

Step-by-step Instructions

Follow these clear, sequential steps to make Poblano Macaroni and Cheese. The list below respects the ingredient amounts and keeps the overall order true to the original recipe while improving clarity and flow.

Preheat your oven broiler or heat a gas burner. Place the 2 whole Poblano chiles on a baking sheet or directly on the burner and char them until the skins are blackened and blistered on all sides. Rotate as needed for even charring. This should take several minutes under a broiler or by turning over a gas flame.
Transfer the charred poblanos to a bowl and cover tightly with plastic wrap or a lid for 10 minutes. This steams the peppers and loosens their skins, making them easier to peel.
While the peppers steam, bring a large pot of salted water to a boil. Add 8 ounces elbow pasta and cook until al dente according to package instructions. Reserve about 1/2 cup of pasta cooking water, then drain the pasta in a colander. Set the drained pasta aside.
Once the poblanos are cool enough to handle, peel off the charred skins using your fingers or a small knife. Cut off the stems, remove the seeds and membranes if you prefer milder heat, and chop the peppers into bite-sized pieces. Measure and set aside.
In a large skillet or medium saucepan, melt 2 tablespoons unsalted butter over medium heat. Add 4 cloves of minced garlic and cook, stirring constantly, until fragrant—about 30 seconds to 1 minute. Be careful not to brown the garlic.
Sprinkle 2 tablespoons all-purpose flour over the melted butter and garlic, and whisk constantly for 1 to 2 minutes to form a roux. This step cooks out raw flour taste and helps thicken the sauce.
Gradually pour in 1-1/2 cups whole milk while whisking continuously to prevent lumps. Increase the heat to medium-high and continue to whisk until the mixture begins to simmer and thickens slightly, about 3 to 5 minutes.
Stir in 1 teaspoon mustard powder, 1/4 teaspoon cayenne powder, and 1/2 teaspoon ground cumin. Allow the spices to bloom in the warm sauce for about 30 seconds, whisking to combine.
Add 4 cups grated white cheddar to the sauce a handful at a time, whisking or stirring until fully melted and smooth before adding more. If the sauce becomes too thick, thin it with a splash of the reserved pasta cooking water until you reach a saucy consistency.
Season the cheese sauce with 1 teaspoon Kosher salt and 1 teaspoon black pepper, tasting and adjusting to your preference. Stir in 1 teaspoon lime zest and 1/2 cup chopped cilantro to bring brightness to the sauce.
Fold the chopped poblanos into the cheese sauce, mixing until they are evenly distributed. Then add the drained elbow pasta and stir gently to coat every piece with the cheesy poblano sauce.
Transfer the macaroni and cheese to an ovenproof dish if you prefer a baked top, or keep it in the skillet for stovetop serving. Sprinkle 1/2 cup Cotija cheese evenly over the top if desired. If you bake, place the dish under the broiler for 2 to 4 minutes just to lightly brown and set the Cotija, watching carefully to avoid burning.
Remove from heat, let rest for 3 minutes to thicken slightly, then garnish with a few extra cilantro leaves or a small pinch of lime zest before serving. Serve warm and enjoy.

Serving suggestions

This Poblano Macaroni and Cheese pairs beautifully with simple sides that cut through the richness: a crisp green salad with a tangy vinaigrette, roasted cherry tomatoes, or some citrusy slaw. For a main course, add a grilled chicken breast or a pan-seared fish fillet on the side. Leftovers reheat well in a skillet over low heat with a splash of milk to loosen the sauce.

Make-ahead and storage

You can prepare the sauce and roast the poblanos a day ahead, then refrigerate them separately from the cooked pasta. Reheat the sauce gently on the stovetop, stir in the pasta, and finish with Cotija before serving. Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently to preserve the texture—high heat can make the cheese separate.

Notes on ingredients and technique

Poblano chiles: These are mild, flavorful peppers. Roasting intensifies their flavor and adds a smoky note. If you can’t find poblanos, aneroid or ancho chiles can work but may shift the flavor profile.
White cheddar: Freshly grate the cheese for the best melt and texture. Pre-shredded cheeses often contain anti-caking agents that can affect smoothness.
Cotija cheese: Used as a finishing touch, Cotija offers a crumbly, salty contrast. Sprinkle it at the end so it retains texture.
Milk: Whole milk keeps the sauce rich and silky. If you need a slightly lighter option, try a 2% and note the sauce will be less decadent.

Common troubleshooting

If the sauce is thin: Whisk in a small amount of additional grated cheese and simmer gently until it thickens, or make a quick slurry with 1 teaspoon flour and a splash of milk, whisked in slowly.
If the sauce is grainy or separated: Remove from heat and whisk in a cold pat of butter or a few tablespoons of milk to bring it back together. Avoid boiling the sauce after the cheese is added.
If the cheese clumps: Add a little reserved pasta water while stirring to smooth it out. Stir gently and don’t overheat.
