Chili Crisp Fettuccine Alfredo

Chili Crisp Alfredo Ingredients

A complete list of ingredients and amounts can be found in the recipe card below.

Fettuccine: Long noodles that hold the creamy sauce and chili crisp in every strand. Follow the package directions to cook it to al dente.
Butter: Rich base that carries the chili flavor through the whole dish.
Chili crisp: Spicy crunchy chili oil that adds heat, texture and savory depth.
Garlic: Fresh sharp flavor that keeps the creaminess bright.
Heavy cream: Creates a smooth velvety sauce that coats the noodles.
Parmesan: Cheese that melts into the sauce and adds a nutty salty finish. Pre-grated cheese often has coatings that stop it melting well, so I recommend freshly grated Parmesan for a smoother sauce and better flavor.
Green onions: Fresh garnish that brings color and a mild onion bite on top.

Cook the pasta: Cook the fettuccine in salted water until al dente, then drain and reserve some pasta water.
Melt the butter: Warm the butter in a very large skillet or Dutch oven.
Add chili crisp and garlic: Stir in chili crisp and garlic and cook until fragrant.
Make the cream mixture: Whisk in the cream and a pinch of salt and pepper and keep the sauce over a low heat.
Add the noodles: Use tongs to transfer the hot fettuccine into the skillet so a little pasta water comes along with the noodles.
Melt in the Parmesan: Sprinkle in the Parmesan and toss until the pasta is coated in a glossy, creamy sauce.
Adjust the texture: Add small splashes of the reserved pasta water as you toss so the sauce stays smooth and loose enough to coat.
Finish and serve: Taste, add more chili crisp if you like, then divide among serving dishes and top with extra chili crisp, Parmesan and green onions. Serve immediately.

Substitutions and Variations

Gluten-free pasta option: Swap the regular fettuccine for gluten-free fettuccine, cook it just to al dente and handle it gently when you toss it in the sauce so it doesn’t break.
Dairy-free creamy option: Use dairy-free butter or olive oil instead of butter and full fat coconut milk or a rich plant based cream instead of heavy cream, then finish with a dairy-free Parmesan style cheese.
Protein add ins: Stir in cooked shrimp, sliced grilled chicken or crispy bacon pieces at the end so the pasta turns into a full one pan meal.
Vegetable boost: Fettuccine alfredo with spinach is always good so feel free to toss in a handful of baby spinach to wilt in the hot sauce. Alternatively, add peas or sautéed mushrooms or bell pepper for extra color and texture.
Heat control: Choose a mild chili crisp for gentle warmth or spoon a spicy chili crisp oil over individual bowls so spice lovers can turn up the fire.

Serving Suggestions

With bread: Enjoy this flavorful dish with air fryer garlic bread or homemade focaccia on the side. 
With a salad: A Caesar salad or tomato burrata salad would pair nicely.
With vegetables: Consider smoked asparagus or roasted Brussels sprouts or broccoli.
As a side dish: Serve the chili crisp fettuccine alfredo as a side with grilled Italian steak, roasted chicken or Italian sliders.

How to Store

Store: Keep leftover chile crisp fettuccine alfredo in an airtight container in the refrigerator for up to 3 days. The sauce will thicken as it sits.
Freeze: Freezing isn’t recommended because the creamy sauce can separate and turn grainy after thawing.
Reheat: Put it in a skillet and warm over low heat with a splash of water or cream, tossing until the noodles loosen and the sauce turns smooth again.
