Viral Green Spaghetti — or espagueti verde, as it is known in Mexico where the dish originates — is having a serious moment online right now, with search interest up more than 50 percent this year and recipe videos racking up millions of views across TikTok, Instagram Reels, and Facebook. It takes everything you love about a creamy pasta dinner and gives it a smoky, garden-fresh twist: roasted poblano peppers blended with tangy Greek yogurt, bright cilantro, and garlic into a velvety emerald sauce that clings to every strand of spaghetti.
What makes this version special is that it is genuinely healthy comfort food. Instead of heavy cream and butter, the sauce gets its luscious texture from Greek yogurt and a little low-fat cream cheese, which means high protein and far less saturated fat without sacrificing an ounce of creaminess. The poblanos bring a gentle smoky heat — mellow and warm rather than spicy — while queso fresco and toasted pepitas on top add salty, crunchy contrast. Serve it as a vibrant weeknight dinner, a meatless main for guests, or a colorful side dish at your next gathering; it tastes like a restaurant dish but comes together in about 40 minutes.
Why You’ll Love This Green Spaghetti
- Smoky and silky: Charred poblano peppers give the sauce a deep, smoky flavor and a gorgeous green color that makes the dish look as good as it tastes.
- Genuinely light: Greek yogurt replaces heavy cream, so you get all the creamy comfort with a fraction of the fat — plus a serious protein boost.
- Weeknight friendly: One pot for pasta, one blender for sauce, and about 40 minutes start to finish, most of it hands-off while the peppers roast.
- Kid-approved and crowd-pleasing: The heat level is very mild, the color is fun, and the creamy texture is pure comfort — picky eaters love it.
- Meal-prep ready: The sauce holds beautifully in the fridge and reheats well, so you can make a batch and enjoy it all week.
- Endlessly flexible: Serve it meatless, add chicken or shrimp for extra protein, or fold in vegetables — it adapts to whatever you have on hand.
Ingredients
For the roasted poblano sauce
- 4–5 poblano peppers (about 1 pound)
- 1/2 cup plain Greek yogurt (full-fat or 2%)
- 1/4 cup low-fat cream cheese, softened (or an extra 1/4 cup Greek yogurt)
- 3 cloves garlic
- 1/2 cup fresh cilantro leaves, plus extra for garnish
- 1/2 cup low-sodium chicken or vegetable broth
- 1/2 teaspoon ground cumin
- 1 teaspoon kosher salt, plus more to taste
- 1/2 teaspoon freshly ground black pepper
- 1 tablespoon olive oil
For the pasta and toppings
- 12 oz (340 g) spaghetti
- 1 cup reserved pasta water (you may not need it all)
- 1/2 cup crumbled queso fresco
- 2 tablespoons toasted pepitas (pumpkin seeds)
- Extra fresh cilantro leaves, for garnish
- Lime wedges, for serving (optional)
Instructions
- Blacken the poblanos: Position an oven rack 4–6 inches from the broiler element and heat the broiler to high. Place the poblano peppers on a foil-lined baking sheet and broil for 10–12 minutes, turning every 3–4 minutes with tongs, until the skins are fully blackened and blistered on all sides. Fully blackening the peppers is essential — that char is where the signature smoky flavor comes from. (Alternatively, char them directly over a gas burner flame with tongs, turning until blackened all over.)
- Steam the peppers: Transfer the blackened peppers to a bowl and cover tightly with a plate or plastic wrap. Let them steam for 10 minutes — this loosens the skins and makes them easy to peel.
- Peel, stem, and seed: Using your fingers or a paper towel, rub the blackened skins off the peppers; they should slip off easily. Remove the stems and pull out the seeds and inner membranes. A few flecks of char left behind are fine and add flavor, but the seeds can add bitterness, so remove them all.
- Blend the sauce: Add the peeled poblanos to a high-speed blender along with the Greek yogurt, cream cheese, garlic, cilantro leaves, broth, cumin, salt, pepper, and olive oil. Blend until completely smooth and silky, scraping down the sides once or twice. Taste and adjust the salt — the sauce should be bright, smoky, and well seasoned.
- Cook the spaghetti: Bring a large pot of generously salted water to a rolling boil. Cook the spaghetti until just al dente, about 1 minute less than the package directions. Before draining, reserve 1 cup of the starchy pasta water — this is liquid gold for bringing the sauce together. Drain the pasta and return it to the pot.
- Warm the sauce gently: Pour the blended poblano sauce over the drained spaghetti in the pot and set over low heat. Warm everything together gently for 2–3 minutes, tossing constantly, until the sauce is heated through and clings to the pasta. Do not let the sauce come to a hard boil — Greek yogurt can split and turn grainy at a rolling simmer. If the sauce looks too thick, add reserved pasta water a few tablespoons at a time until it coats each strand in a silky, glossy layer.
- Garnish and serve: Divide the green spaghetti among four bowls. Top each with crumbled queso fresco, a sprinkle of toasted pepitas, and extra cilantro leaves. Serve immediately with lime wedges on the side for anyone who likes a bright squeeze of acidity.
Tips for the Best Green Spaghetti
- Char the peppers fully. Under-roasted poblanos taste grassy rather than smoky. You want the skins nearly black and blistered all over before they come out of the oven.
- Keep the sauce off a boil. Yogurt-based sauces split when boiled hard. Gentle, low heat is all you need — the sauce only has to warm through, not cook.
- Do not skip the pasta water. The starch in pasta water emulsifies the sauce so it hugs the noodles instead of pooling at the bottom of the bowl. Add it gradually; you may need less than the full cup.
- Salt the pasta water generously. Pasta absorbs water as it cooks, and well-salted water is your first and best chance to season the noodles themselves. Aim for water that tastes like the sea.
- Use room-temperature yogurt. Cold yogurt straight from the fridge is more likely to curdle when it hits warm pasta. Let it sit on the counter while the peppers roast and blend it at room temperature.
- Taste the peppers first. Poblanos are usually mild, but every pepper is different. If yours run hot, use one fewer pepper or scoop the sauce a little thinner with extra yogurt to balance the heat.
Variations
- Add protein: Toss in sliced grilled chicken breast, sautéed shrimp, or a can of drained white beans to turn it into a heartier, even more protein-packed meal.
- Make it vegan: Swap the Greek yogurt and cream cheese for unsweetened plant-based yogurt and use vegetable broth; finish with a sprinkle of nutritional yeast instead of queso fresco.
- Roast some vegetables in: Fold in roasted zucchini, corn, or mushrooms with the pasta for extra color, fiber, and texture.
- Go extra creamy: Stir a handful of shredded mozzarella or Monterey Jack into the warm pasta off the heat for a richer, cheesier sauce — less light, but irresistible.
- Try a different shape: The sauce works beautifully on penne, rigatoni, or fettuccine too. Short shapes hold little pools of the green sauce in every bite.
Storage & Reheating
Store leftover green spaghetti in an airtight container in the refrigerator for up to 4 days. The sauce will thicken as it chills, which is normal. To reheat, warm it in a skillet over low heat with a splash of water or broth, stirring gently until the sauce loosens and turns creamy again — microwaving in 30-second bursts with a stir between also works. Because the sauce is yogurt-based, reheat gently rather than blasting it with high heat. The sauce can also be made ahead on its own: refrigerate it in a jar for up to 5 days, then warm and toss with freshly cooked pasta whenever you want dinner in 15 minutes. Freezing is not recommended, as yogurt-based sauces can separate when thawed.
Frequently Asked Questions
Is green spaghetti spicy?
Not really — poblano peppers are one of the mildest chile peppers, with gentle warmth and lots of smoky flavor rather than real heat. Most people, including kids, find this dish pleasantly mild. If you are sensitive to spice, taste your peppers before blending and remove every seed and membrane, since that is where any heat concentrates.
Why did my sauce curdle or look grainy?
This happens when a yogurt-based sauce gets too hot. Greek yogurt proteins tighten and separate at high temperatures. To prevent it, warm the sauce over low heat and never let it reach a hard boil. Using room-temperature yogurt and full-fat or 2% Greek yogurt (rather than nonfat) also makes the sauce more stable.
Can I use canned green chiles instead of roasting poblanos?
In a pinch, yes — two 4-ounce cans of fire-roasted green chiles will get you a serviceable sauce. But the deep smoky flavor that makes this dish special comes from freshly charred poblanos, so roast them yourself when you can. The broiler method is mostly hands-off and only takes about 12 minutes.
Is this recipe actually healthy?
For a creamy pasta dish, absolutely. The sauce is built on Greek yogurt instead of heavy cream, so it is high in protein and much lower in saturated fat than a traditional cream sauce, while the poblanos, cilantro, and garlic pack in vegetables and flavor. Each serving lands around 400 calories with roughly 18 grams of protein. Use whole-wheat or legume-based spaghetti to add even more fiber and protein.
