Imagine a bowl of ultra-creamy mac and cheese with ribbons of smoky, charred poblano peppers folded right into the sauce. Every bite delivers that familiar cheesy comfort you grew up loving, with a subtle heat and a deep, roasted flavor that makes you stop and say, wow, where has this been all my life? The cheese sauce is velvety and rich, clinging to every ridge of the pasta, and those soft strips of roasted poblano bring a gentle kick without being overwhelming.
This recipe is perfect for weeknight dinners when you want something cozy but a little more exciting than the usual rotation. It also shines as a crowd-pleasing side dish at backyard cookouts, potlucks, and holiday gatherings. If you have friends who claim they do not like spicy food, serve them a bowl of this anyway. The heat from poblanos is mild and earthy, nothing sharp or aggressive, just warmly present in the background.
SaveI first made this on a rainy Sunday afternoon when I had a bag of poblanos from the farmers market and a serious craving for comfort food. I started roasting the peppers over an open flame, their skins blistering and turning glossy, and the whole kitchen filled with this incredible smoky aroma. I knew immediately they were going straight into a cheese sauce. That first batch was so good I made it again three days later, and now it is a permanent fixture in my recipe lineup.

Instructions
- Roast the Poblanos
Set your oven broiler to high and line a baking sheet with foil. Rub the poblano peppers all over with olive oil and sprinkle with salt. Place them directly on the baking sheet and broil for 10 to 12 minutes, turning every 3 to 4 minutes, until the skins are completely charred and blistered on all sides. The peppers should be soft and slightly collapsed when done.
- Steam and Peel the Peppers
Transfer the charred peppers to a bowl and cover tightly with plastic wrap or a plate. Let them steam for 10 minutes. This steaming step is key because it loosens the skins so they slide right off. Once cooled enough to handle, peel away and discard the charred skins, then slice the peppers open and remove the seeds and stems. Cut the roasted flesh into thin strips and set aside.
- Cook the Pasta
Bring a large pot of water to a boil and add the kosher salt. Add your pasta and cook according to package directions until just al dente, about 1 minute less than the package suggests. You want the pasta slightly underdone because it will continue cooking in the oven. Drain the pasta well and set aside, tossing it lightly with a drizzle of olive oil to prevent sticking.
- Preheat the Oven
Preheat your oven to 375 degrees Fahrenheit. Lightly grease a 9x13-inch baking dish with butter or nonstick spray and set it aside while you prepare the cheese sauce.
- Make the Roux
In a large, heavy-bottomed saucepan or Dutch oven, melt the 4 tablespoons of butter over medium heat. Once the butter is foamy, whisk in the flour and cook, whisking constantly, for about 2 minutes. The mixture should look like a pale paste and smell slightly nutty. This step cooks out the raw flour taste and builds the base of your sauce.
- Build the Cheese Sauce
Gradually pour in the warm milk and heavy cream, whisking continuously to prevent lumps. Increase the heat to medium-high and cook, stirring frequently, for 5 to 7 minutes until the sauce thickens enough to coat the back of a spoon. Stir in the garlic powder, smoked paprika, cumin, onion powder, salt, and black pepper. Reduce the heat to low before adding the cheeses.
- Melt the Cheeses
Add the cream cheese first, stirring until it is fully melted and smooth. Then add the shredded cheddar, Monterey Jack, and Gruyere in handfuls, stirring after each addition. Keep the heat on low because high heat can cause the cheese to seize up and turn grainy. The finished sauce should be glossy, thick, and smooth. Taste and adjust the salt if needed.
- Combine Pasta, Peppers, and Sauce
Add the drained pasta and the roasted poblano strips to the cheese sauce and stir everything together until the pasta is evenly coated and the pepper strips are distributed throughout. Pour the mixture into the prepared baking dish and spread it out into an even layer.
- Prepare the Breadcrumb Topping
In a small bowl, combine the panko breadcrumbs, melted butter, shredded cheddar, and smoked paprika. Stir until all the breadcrumbs are evenly coated with the butter. Sprinkle the topping evenly over the mac and cheese, covering the surface as completely as possible for maximum crunch.
- Bake Until Golden
Bake uncovered in the preheated oven for 20 to 25 minutes, until the topping is golden brown and crispy and the sauce is bubbling around the edges. If you want extra browning on top, switch the broiler on for the last 2 to 3 minutes, keeping a close eye so the breadcrumbs do not burn.
- Rest and Serve
Remove the baking dish from the oven and let the mac and cheese rest for 5 minutes before serving. This brief resting time lets the sauce settle so it scoops cleanly and does not run all over the plate. Garnish with fresh cilantro, sliced green onions, or a light sprinkle of extra smoked paprika if you like.
Substitutions and variations
- Use Anaheim peppers instead of poblanos for a milder flavor, or try canned roasted green chiles if you are short on time.
- Swap cavatappi or shells for the elbow macaroni since they hold sauce beautifully in their curves and ridges.
- Replace Gruyere with smoked gouda for an even deeper smoky flavor throughout the sauce.
- Use 2% milk in place of whole milk if that is what you have on hand, though the sauce will be slightly less rich.
- Make it gluten-free by using your favorite gluten-free pasta and substituting a 1:1 gluten-free flour blend for the all-purpose flour in the roux.
Chloe's tips
- Warm your milk before adding it to the roux so the sauce comes together more smoothly and quickly without any lumps.
- Shred your cheese from a block rather than using pre-shredded bags. Pre-shredded cheeses contain anti-caking agents that can make the sauce grainy.
- Do not skip the steaming step after broiling the peppers. It makes peeling them so much easier and prevents you from losing good pepper flesh along with the skin.
- Cook the pasta just shy of al dente since it will keep cooking in the oven and you do not want mushy noodles in your final dish.
- If your sauce feels too thick before baking, splash in a little warm milk and stir to loosen it. It will thicken a bit more in the oven so you want it just slightly saucier than you think you need.
How to store it
- Store leftovers in an airtight container in the refrigerator for up to 4 days.
- To reheat, place portions in a microwave-safe dish with a splash of milk, cover loosely, and microwave in 60-second intervals, stirring between each, until hot and creamy.
- To reheat in the oven, cover the dish with foil and bake at 350 degrees Fahrenheit for 15 to 20 minutes, adding a splash of milk over the top before covering to restore creaminess.
- This dish can be frozen before baking. Assemble everything including the topping, cover tightly with foil, and freeze for up to 2 months. Bake straight from frozen at 375 degrees Fahrenheit for 45 to 55 minutes, removing the foil for the last 10 minutes.
Serving suggestions
This mac and cheese is satisfying enough to stand on its own, but it also pairs beautifully with a range of dishes and toppings.
- Serve alongside grilled chicken thighs or crispy fried chicken for a hearty dinner plate
- Top individual servings with a drizzle of hot sauce or a spoonful of salsa verde for extra brightness
- Pair with a crisp green salad dressed with lime vinaigrette to balance the richness
- Serve as a side dish at barbecues alongside pulled pork, brisket, or grilled corn
- Garnish with fresh cilantro, sliced pickled jalapenos, or a dollop of sour cream for a fun Tex-Mex inspired finish
Frequently asked questions
How spicy is this mac and cheese?
Poblano peppers are quite mild on the heat scale, usually registering between 1,000 and 2,000 Scoville units. The heat is gentle, earthy, and smoky rather than sharp or fiery. Most people who are sensitive to spice find poblanos very approachable, but if you want zero heat you can swap in roasted red bell peppers instead.
Can I make this on the stovetop without baking it?
Absolutely. After combining the pasta, peppers, and cheese sauce in the pot, simply serve it right away. It will be incredibly creamy and saucy. You will miss the crunchy breadcrumb topping, but a stovetop version is just as delicious and even faster on busy weeknights.
Can I make this ahead of time?
Yes, you can assemble the entire dish, cover it tightly, and refrigerate it for up to 24 hours before baking. When you are ready to cook, let it sit at room temperature for about 20 minutes and then bake as directed, adding 5 to 10 extra minutes to the baking time since it is starting cold.
What is the best pasta shape for this recipe?
Elbow macaroni is the classic choice and works great, but cavatappi, shells, or rigatoni are all fantastic options. Shapes with ridges, curves, or hollows hold onto the thick cheese sauce really well and give you more sauce in every bite.
My cheese sauce turned out grainy. What went wrong?
Grainy sauce usually happens when the heat is too high while melting the cheese, or when pre-shredded cheese with anti-caking agents is used. Always add cheese over low heat and shred it fresh from a block for the smoothest, creamiest results. If your sauce does seize up, try whisking in a splash of warm milk over very low heat to bring it back together.
