Why This Spaghetti, Popular in Mexico, Is Green
Green spaghetti is popular because of its fresh, slightly tangy and somewhat spicy flavor. Tomatillos lend distinctive acidity that really cuts the richness of the pasta and any other proteins you choose to stir in. Jalapeños and garlic contribute aromatic depth, while cilantro brings fresh green brightness that helps lift the dish.
This is not just shrimp pasta, it’s a dinner made from only five ingredients that takes 30 minutes to make! And since it uses frozen shrimp, hopefully you’ll have most of these in stock so that you can make this anytime. It’s also visually striking, with a vivid green sauce that turns a plain-flavored pasta into something festive and special.
Understanding the Flavor Profile
The secret to Mexican green spaghetti is balance. The tart tomatillos are softened and pureed into a smooth sauce. Garlic and onions provide depth, while jalapeños or serrano peppers bring moderate heat. A little cream or olive oil can also cut the acidity and yield a luscious texture.
The sauce is usually given a quick cook prior to serving to marry flavors. Combined with just-tender spaghetti, you’re left with pasta that’s both full-flavored and fragrant, coated in a sleek blanket of green to which the word “velvety” actually applies.

For a Mexican classic green spaghetti, you must prepare:
- Spaghetti – Cooked al dente
- Tomatillos – Husked and rinsed
- Onion – Roughly chopped
- Garlic – Minced

Essential Tools
You will need a couple of basic kitchen tools:
- Large pot – For boiling pasta
- Colander – For draining spaghetti
- Blender – For the green sauce
- Skillet or medium saucepan – For cooking the sauce
- Knife – To cut up your veggies and herbs.
- Cutting board – For prep
- Wooden spoon or spatula – So you can stir.
- Bowl or a serving platter – To serve the salad in.
These gadgets facilitate safe, easy, and efficient cooking.
Preparing the Pasta
Start bringing a large pot of salted water to the boil. Add the spaghetti and cook until al dente according to the package instructions. Al dente pasta has a little bit of bite; it stands up when you toss it with sauce.
Decant the spaghetti into a colander to drain and keep back a cup of pasta water. (You’re going to want the reserve of this starchy water later on for adjusting the sauce’s texture.)
Making the Green Sauce
The green sauce, which begins by roasting or boiling tomatillos, jalapeño and onion until they’re soft. Fresh garlic can be included or roasted for an extra concentrated taste. You puree the rehydrated vegetables (from above) with fresh cilantro, salt, and black pepper.
Heavy cream or Mexican crema is an optional addition if you want a more mellow creamy sauce. What you’re after here is a smooth, bright green sauce that’s tangy and herbaceous with just enough of a kick to coat your spaghetti.
Cooking the Sauce
In a skillet or saucepan, heat olive oil over medium heat. Add the pureed green sauce to the pot and simmer 5–7 minutes, stirring often. It lets the flavors marry, mellows out that raw acidity from the tomatillos, and results in a bit of sauce thickening up.
Season to taste and add more salt/pepper if needed. If the sauce is too thick, stir in a splash of reserved pasta water until it has a silky texture.
Combining Pasta and Sauce

Add the cooked spaghetti to the sauce, tossing to finish cooking and coat them. Gently toss in the pasta to coat well. Ensure every strand is well coated with the green sauce for the best taste!
For added lavishness, drizzle with a little olive oil or add some cream. Season with salt and pepper to taste If necessary, tip the balance between sauce and pasta
Serving Suggestions
While Mexican green spaghetti tastes best when it is served hot, a little sprinkle of fresh chopped cilantro and some grated cheese (think Cotija or Parmesan) on top makes for the prettiest final touch.
Top with grilled chicken, shrimp or crispy tortilla strips for a heartier meal. Enjoy it with a side of fresh salad, avocado slices or serve with a squeeze of lime if you prefer things more bright.
Storage and Make-Ahead Tips
Leftover green spaghetti can be refrigerated in a sealable container for 2 – 3 days. Reheat gently on the stovetop over low heat, adding a little water or cream if the sauce has thickened.
The sauce can also be done in advance and kept separate from the pasta. This enables you to act fast so your pasta doesn’t get all mushy.
Flavor Enhancements
Though the original recipe is tasty on its own, there are plenty of ways to take it up a notch. Add lightly roasted poblano peppers for smoky complexity, or a pinch of cumin or smoked paprika for earthy heat.
For a creamier version, you could add some sour cream or cream cheese. A squeeze of lime juice at the end brightens everything and toasted pumpkin seeds provide a firm crunch for texture contrast.
Common Mistakes to Avoid
Cook the spaghetti too long and it will become mushy and won’t absorb the sauce. Always aim for al dente. Overblending the sauce could leave it with overly loose texture; if this happens, simmer a little longer to thicken.
Also, watch out for the heat in your peppers—begin with less if you’re sensitive to spiciness, then up it to taste.
