This Mexican green spaghetti (espagueti verde) is a creamy pasta made with roasted poblano peppers, onions, garlic, crema, and chicken bouillon. The creamy green sauce coats every strand of spaghetti for a cozy dish that comes together in just 30 minutes. Perfect for busy weeknights but impressive enough for guests, this easy pasta recipe delivers bold flavor with minimal effort.
Cook the pasta: Bring a large pot of water to a rolling boil. Add 1 tablespoon of salt, then cook the spaghetti according to package directions. Drain and set aside.
While the pasta is cooking, roast the poblanos: Turn your oven broiler to high (or preheat to 550°F). Place the poblano peppers on a baking sheet or directly on the oven rack. Broil for 5 minutes per side, flipping once, until the skins are charred and blistered.
Steam and peel: Once the peppers are roasted, place them in a covered bowl or plastic Ziplock bag and seal it for about 5 minutes to let them steam. Then rub off the loosened skins with your fingers or rinse gently under cool water; the skins should slide right off. Remove the stems (and seeds if you want less heat).
Blend the sauce: Add the peeled poblanos to a blender with the white onion, garlic, crema, milk, and chicken bouillon paste. Blend until smooth. Taste and adjust with salt if needed. (Note: I add ½ teaspoon of salt)
Simmer the sauce: Pour the poblano sauce into a skillet over medium-low heat. Bring to a gentle simmer and cook for 10 minutes, stirring occasionally, until slightly thickened.
Toss pasta: Add the cooked spaghetti to the skillet and toss until every strand is coated. Serve with crumbled cotija cheese and fresh cilantro.
Notes
Your pasta water should taste like the sea, this is your only chance to season the pasta itself. Once the water begins to boil, add 1 tablespoon of salt before adding the pasta.
Save ½ cup of pasta water just in case you want to loosen the sauce later.
When simmering the sauce keep the heat on the lower side to prevent the crema from separating. You’re looking for a gentle bubble, not a rapid boil.
Storage: Let the pasta cool completely, then transfer to an airtight container and refrigerate for up to 3–4 days.
