Roasted Poblano and Smoked Gouda Mac and Cheese

I first discovered this smoky, creamy twist Roasted Poblano and Smoked Gouda Mac and Cheese during a trip through the American Southwest 🇺🇸—specifically in New Mexico, where roasted peppers are practically a way of life.

Poblanos, with their mild heat and deep, earthy flavor, are often roasted to perfection and added to all kinds of dishes.

Pairing them with smoked gouda felt like a delicious reflection of the region’s love for bold, smoky flavors and comforting food that brings warmth to every bite.

Ingredients

Here are the ingredients that come together to create this incredible dish.

• 4 cups dry small pasta – I recommend shapes like cavatappi or small shells because they have ridges and pockets that hold onto the cheese sauce beautifully.
• 4 fresh poblano peppers – These peppers offer a mild heat and a wonderfully smoky flavor when roasted.
• 6 tablespoons unsalted butter – Using unsalted butter allows you to control the saltiness of the final dish.
• ¼ cup all-purpose flour – This is the foundation of our roux, which thickens the cheese sauce to the perfect consistency.
• 2 ¼ cups heavy cream – For the richest, most decadent sauce, heavy cream is a must.
• 2 teaspoons mustard powder – This is a classic secret ingredient that enhances the cheese flavor without making the dish taste like mustard.
• ¼ cup mascarpone cheese – It adds a silky, luxurious texture and mild creaminess that rounds out the sauce.
• ⅓ cup smoked gouda cheese – The star of the show. Be sure to grate it fresh from a block for the smoothest melt.
• ⅓ cup aged white cheddar cheese – Provides a sharp, tangy counterpoint to the other rich cheeses.
• ⅓ cup sharp cheddar cheese – Another layer of classic cheddar flavor that makes this dish undeniably mac and cheese.
• 1 teaspoon Cajun seasoning – Adds a subtle, complex warmth that complements the poblanos.
• ½ teaspoon cayenne pepper – For an extra kick of heat. You can adjust this to your personal preference.
• ½ teaspoon smoked paprika – This deepens the smoky notes from the gouda and roasted peppers.
• ½ teaspoon black pepper – Freshly ground pepper is always best for maximum flavor.
• ½ teaspoon kosher salt – To taste; season the sauce at the end.
• ¼ cup panko bread crumbs – These Japanese-style breadcrumbs create an irresistibly crunchy topping.

Note: This recipe makes enough for several servings, about 8 portions.

Variations

This recipe is fantastic as is, but it’s also incredibly versatile. Here are some simple swaps and additions you can try.

• For a spicier kick: Swap one or two of the poblano peppers for jalapeños or serrano chiles. You could also add a pinch more cayenne pepper to the sauce.
• To make it milder: Use roasted red bell peppers instead of poblanos for a sweeter flavor with no heat. You can also omit the cayenne pepper entirely.
• Protein additions: Crispy, crumbled bacon or cooked prosciutto are excellent additions. Stir them into the sauce with the pasta for a savory, meaty flavor.
• Different cheeses: Feel free to experiment! Gruyère, fontina, or even brie would work well in place of one of the cheddars for a different flavor profile.
• Gluten-free option: Use your favorite gluten-free pasta, a cup-for-cup gluten-free flour blend for the roux, and gluten-free panko breadcrumbs for the topping.

Equipment You Need

• Baking Sheet: You’ll need this to roast the poblano peppers until their skins are nicely charred.
• Large Pot: This is for boiling the pasta and can also be used to make the cheese sauce.
• Whisk: Essential for creating a smooth, lump-free roux and cheese sauce.

• Baking Dish: A 7×11-inch or 9×9-inch dish is the perfect size for baking the mac and cheese to golden perfection.

How to Make Roasted Poblano and Smoked Gouda Mac and Cheese?

This recipe might seem like it has a lot of steps, but it comes together quite easily. By preparing the components in order, you’ll have a restaurant-quality meal ready in no time. We start by roasting the peppers to bring out their flavor, then cook the pasta while we build a rich, velvety cheese sauce from a simple roux base. Finally, we combine everything and bake it until bubbly and golden.

Step 1: Roast the Poblano Peppers

First, prepare your poblano peppers. Cut them into 1-inch strips, removing the stems and seeds. Arrange the strips skin-side up on a baking sheet and broil on high for 6-10 minutes. You want the skins to become mostly black and blistered. Once charred, remove them from the oven and place them in a zip-top bag for about 5 minutes. This traps the steam and makes the skins incredibly easy to peel off. After they’ve steamed, peel the skins, finely chop the pepper strips, and set them aside.

Step 2: Cook the Pasta

While the peppers are roasting, bring a large pot of salted water to a rolling boil. Add your pasta and cook it for about 75% of the time indicated on the package instructions. You want it to be slightly undercooked, as it will finish cooking in the oven. Drain the pasta and set it aside. If it starts to stick, you can toss it with a tiny drizzle of olive oil.

Step 3: Create the Cheese Sauce

In the same large pot, melt the butter over medium heat. Whisk in the flour and cook for about a minute, stirring constantly, to create a blonde roux. This will thicken your sauce. Slowly pour in the heavy cream while continuing to whisk to prevent lumps. Add the mustard powder and cook for about 5 minutes, until the sauce thickens. Reduce the heat to low and stir in the mascarpone, smoked gouda, white cheddar, and sharp cheddar. Continue stirring until the cheeses are fully melted and the sauce is smooth.

Step 4: Assemble and Bake

Now it’s time to bring it all together. Preheat your oven to 350°F. Add the chopped roasted poblanos, Cajun seasoning, cayenne, smoked paprika, salt, and pepper to the cheese sauce. Give it a taste and adjust the seasonings if needed. Gently fold in the cooked pasta until it’s fully coated.

Transfer the mixture to your baking dish and sprinkle the panko breadcrumbs evenly over the top. Bake for 15-20 minutes, or until the sauce is bubbling around the edges. For a golden-brown top, finish by broiling on high for 1 minute, but watch it carefully to prevent burning. Let it rest for 5 minutes before serving.

🇺🇸 A Southwestern Gem from the Heart of New Mexico

While traveling through the sun-drenched landscapes of New Mexico, USA, I discovered how deeply roasted peppers are woven into the region’s culinary identity. 

Poblanos, with their smoky aroma and gentle spice, are a staple in Southwestern kitchens, symbolizing the area’s love for bold, rustic flavors. 

This Roasted Poblano and Smoked Gouda Mac and Cheese perfectly captures that spirit uniting the comforting soul of American mac and cheese with the rich, earthy essence of New Mexico’s pepper tradition.

Additional Tips for Making this Recipe Better

• After making this dozens of times, I cannot stress this enough: grate your own cheese! Pre-shredded cheeses contain anti-caking agents that give the sauce a grainy texture. Buying blocks of cheese and grating them yourself makes a world of difference.
• Don’t overcook your pasta in the initial boil. I find that pulling it out when it’s still got a firm bite is perfect. It will absorb some of the sauce and finish cooking in the oven, resulting in the ideal texture.
• When making the roux, be patient. Cooking it for a minute or two helps get rid of the raw flour taste and adds a subtle nutty flavor to the sauce.
• I like to taste the cheese sauce before adding the pasta. This is your last chance to easily adjust the salt and spice levels to get them just right.

How to Serve Roasted Poblano and Smoked Gouda Mac and Cheese?

In the Southwest, this dish is often served alongside grilled meats or smoky barbecue, capturing the region’s rustic charm.

Pair it with roasted corn on the cob, a crisp Southwestern salad, or even a chilled glass of sweet tea or margarita for the full experience.

Each creamy, peppery bite feels like a journey through the heart of New Mexico’s vibrant food culture.

Make Ahead and Storage

Proper storage is key to enjoying this dish later.

Make Ahead: You can fully assemble the mac and cheese (without the breadcrumb topping) up to 3 days in advance. Cover it tightly and store it in the refrigerator. When ready to bake, let it sit at room temperature for 30 minutes, then add the breadcrumbs and bake as directed, possibly adding 5-10 minutes to the baking time.

Storing: Store any leftovers in an airtight container in the refrigerator for up to 5 days. The sauce will thicken as it cools.

Reheating: The best way to reheat this mac and cheese is slowly. Place it in an oven-safe dish, add a splash of milk or cream to loosen the sauce, cover with foil, and bake at 350°F until warmed through. This prevents the sauce from breaking and becoming oily.
