Creamy Fettuccine Hatch Chile Alfredo

Here’s my go-to hatch chile alfredo recipe, with a smooth, creamy sauce that combines traditional parmesan cream sauce with the mild heat of roasted hatch chiles, fresh garlic, and a touch of nutmeg.

This pasta dish has become my family’s favorite comfort food during hatch chile season. I often make a double batch of the sauce to keep in the fridge for busy weeknights. Nothing better than having a quick, homemade dinner ready to go, right?

What Kind of Hatch Chiles Should I Use?

Hatch chiles come in different heat levels, from mild to extra hot, so you’ll want to choose based on your spice preference. These special peppers are grown in New Mexico’s Hatch Valley and are typically available fresh in late summer (August-September), though you can find them canned or frozen year-round. For this alfredo sauce, either fresh roasted or frozen roasted Hatch chiles will work great – just make sure they’re properly peeled and seeded before using. If you’re new to Hatch chiles, start with mild or medium ones, as they’ll give you that authentic New Mexican flavor without overwhelming heat. Remember, if you’re roasting fresh ones, let them steam in a covered bowl after roasting to make the peeling process much easier.

Options for Substitutions

Need to make some swaps? Here are some helpful substitutions for this creamy pasta dish:

• Hatch chiles: If you can’t find Hatch chiles, you can use poblano peppers or Anaheim chiles instead. Just roast them the same way. For a milder version, try roasted green bell peppers. Keep in mind the flavor will be different, but still tasty!
• Fettuccine: Any long pasta works here – try linguine, spaghetti, or even pappardelle. Just avoid tiny shapes like orzo as they won’t hold up as well with this creamy sauce.
• Shallot: No shallots? Use 1/4 cup finely diced sweet onion or 2 tablespoons of red onion instead.
• Heavy cream: For the cream, you really need to stick with heavy cream here – half and half or milk won’t give you that thick, rich sauce we’re looking for.
• Parmesan: Fresh parmesan is best, but in a pinch, you can use Romano cheese or even Pecorino. Just avoid pre-grated cheese as it won’t melt as smoothly.

Watch Out for These Mistakes While Cooking

The biggest challenge when making Hatch Chile Alfredo is preventing the cream sauce from breaking or becoming grainy – keep your heat on medium-low and stir constantly once the cream is added to maintain a smooth, silky texture. A common mistake is overcooking the pasta; instead, cook it just until al dente since it will continue to soften slightly when tossed with the hot sauce. When working with Hatch chiles, make sure they’re properly roasted, peeled, and seeded – any remaining bits of skin can create an unpleasant texture in your smooth sauce. For the best flavor balance, start by adding half the amount of chiles, then taste and adjust – you can always add more, but you can’t take them away once they’re mixed in. Remember to reserve about 1/2 cup of pasta water before draining your noodles – this starchy liquid is perfect for thinning out the sauce if it becomes too thick.

What to Serve With Hatch Chile Alfredo?

This spicy twist on classic alfredo pasta calls for some simple sides that won’t compete with its rich, creamy flavors. A light green salad with a lemon vinaigrette helps cut through the richness of the sauce, while some crusty garlic bread is perfect for soaking up any extra sauce left on your plate. If you want to add protein, grilled chicken breast or sautéed shrimp work really well with the mild heat of the Hatch chiles. For a complete meal that won’t overwhelm the pasta, roasted asparagus or broccolini makes an excellent veggie side that pairs nicely with the creamy sauce.

Storage Instructions

Keep: This creamy Hatch chile alfredo will stay good in an airtight container in the fridge for up to 3 days. The sauce might thicken up a bit when chilled, but don’t worry – that’s totally normal! Just know that pasta dishes with cream-based sauces are best enjoyed within the first day or two.

Make Ahead: If you want to prep ahead, you can make the sauce separately and store it in the fridge for up to 2 days. When you’re ready to eat, just cook fresh pasta and warm up the sauce – it’s that simple! The roasted Hatch chiles can also be prepped in advance and kept in the fridge for up to 5 days.

Warm Up: To bring your leftover alfredo back to life, warm it gently on the stovetop over low heat, stirring occasionally. Add a splash of cream or milk if the sauce seems too thick. Avoid using the microwave if possible, as it can make the sauce separate and become grainy.

Ingredients

For the chili preparation:

• 1 1/2 cups roasted hatch chiles (peeled and rinsed)

For the fettuccine alfredo:

• 5 tbsp unsalted butter (I like Kerrygold unsalted butter for this)
• 2 chopped garlic cloves (freshly minced for best flavor)
• 1/2 tsp kosher salt
• 1/3 cup grated parmesan cheese (freshly grated preferred for more flavor)
• 1 diced shallot
• 1/2 lb fettuccine pasta
• 1 cup heavy cream (gives better texture and moisture)

For garnish:

• extra grated parmesan cheese

Step 1: Prepare the Hatch Chiles

• 1 1/2 cups roasted Hatch chiles, peeled and rinsed

Remove the stems and seeds from the roasted Hatch chiles and discard them.

Slice the chiles into thin strips, then set them aside until ready to use.

This step ensures the chiles are ready to integrate smoothly into the sauce.

Step 2: Cook the Fettuccine

• 1/2 lb fettuccine pasta

Bring a large pot of salted water to a boil.

Once boiling, add the fettuccine pasta and cook until al dente, about 8 minutes.

Reserve 1/2 cup of the cooking liquid before draining the pasta, then return the cooked pasta to the pan it was boiled in and set aside.

I like to start preparing the sauce while the pasta cooks to save time.

Step 3: Sauté the Aromatics and Chiles

• 5 tbsp unsalted butter
• 1 diced shallot
• sliced Hatch chiles from Step 1
• 2 chopped garlic cloves

While the pasta cooks, melt the butter in a large skillet over medium heat.

Add the diced shallot and sliced Hatch chiles from Step 1, and sauté for about 3 minutes until they begin to soften.

Add the chopped garlic and cook for another 30 seconds until fragrant.

The aromatics add a great base of flavor to the sauce.

Step 4: Simmer the Cream Sauce

• 1 cup heavy cream

Decrease the heat to medium-low and pour in the heavy cream.

Allow the mixture to gently simmer for 5 minutes so the flavors meld and the sauce becomes creamy.

Stir occasionally to prevent the cream from scorching.

Step 5: Combine Pasta with Sauce and Finish

• 1/2 cup reserved pasta cooking liquid (from Step 2)
• 1/3 cup grated parmesan cheese
• 1/2 tsp kosher salt, or to taste
• cooked fettuccine from Step 2

Add the reserved pasta cooking liquid, parmesan cheese, kosher salt, and the cooked fettuccine from Step 2 into the skillet with the cream sauce.

Stir and toss well to thoroughly coat the pasta with the sauce.

Continue cooking for 2 to 3 minutes, until the sauce thickens and the pasta is fully heated through.

For even more flavor, I like to add an extra sprinkle of parmesan cheese at the end.

Step 6: Plate and Garnish

• extra grated parmesan cheese for garnish

Divide the hot fettuccine and sauce into warm serving bowls.

Serve immediately, topping with extra grated parmesan cheese for garnish.
