Tomatillo Pasta Recipe – Fresh, Easy, and Full of Flavor

You know how some recipes happen by accident? That’s exactly how this tomatillo pasta recipe showed up in my kitchen.

I had a bag of tomatillos sitting on the counter, leftover from a salsa I never got around to making, and figured, why not roast them and see what happens? I tossed them in the oven with some garlic and onion, blended it all up with a splash of broth and olive oil, and poured it over spaghetti. It smelled amazing. My daughter took one bite and said, “What is this?!”, then asked for seconds.

That’s when I knew I was onto something.

The sauce is bright and tangy, but rich too, especially if you stir in a little avocado. It’s nothing like your usual tomato-based pasta, and that’s what I love about it. It feels fresh and a little unexpected, but still cozy and simple. No fancy ingredients. Just pantry stuff and a little curiosity.

If tomatillos are new to you, don’t worry, I’ll walk you through exactly how to use them, whether you’re roasting fresh ones or starting with canned. And if you’re wondering, “Do tomatillos really belong in pasta?”, you’re not the only one. I had the same question. Turns out, the answer is absolutely yes.

How This Pasta Happened

This recipe? Total accident.

I bought tomatillos at the market because they looked pretty. No plan. I figured I’d make salsa or something. But they sat on the counter for days, right next to some garlic and a bunch of onions I hadn’t used either.

Then one night, I was just tired. The kind of tired where you boil pasta not because you want it, but because it’s easy and your brain can’t handle a grocery run. The tomatillos were staring at me, so I thought, “Why not?” I roasted them with garlic and onion, threw it all in the blender with a little olive oil and broth, tossed it over hot pasta, and called it dinner.

And… it worked. Really well. My kid took one bite and said, “This is good,” in that way kids do when they’re genuinely surprised. I didn’t measure anything, but I remembered the idea, and the next time I made it, I wrote it down.

That’s how this tomatillo pasta recipe was born, tired, hungry, and winging it.

Since then, I’ve played with it. Some nights I stir in avocado to make it creamy. Other times I throw in spinach or a chopped jalapeño. It’s one of those dishes you can’t really mess up. And if all you have is canned tomatillos? That’s fine too, here’s how I make it work.

I never thought pasta and tomatillos belonged together. But now I make this more often than red sauce. If you’re curious what else you can do with tomatillos, I’ve got a few ideas right here.

Why Tomatillos Just Work in Pasta

The Sauce Just… Works

Okay, so I didn’t plan this sauce. I wasn’t experimenting. I wasn’t trying to “reinvent pasta.” I was just tired, staring at a half-empty pantry and those tomatillos I still hadn’t used.

I roasted them, because honestly, roasting fixes everything. Garlic, onion, tomatillos. Into the oven. That smell alone felt like a little win.

Then I dumped it all in the blender with some olive oil and a splash of broth because it looked too thick. Hit blend, tasted it, and paused. I remember thinking, wait… this might actually be really good.

It was tangy in this way that felt alive, you know? Fresh, but not raw. Smoky from the roast. The garlic was soft and sweet. It wasn’t creamy, but it coated the spoon like it wanted to be.

So I poured it over hot pasta and gave it a toss. That’s it. No cheese. No rules. My daughter walked through, took a bite straight from the pot, and said, “Is this the green pasta now?” Like it had always existed.

Since then, I’ve added things: avocado when I want it silkier, jalapeño if I’m craving heat. Sometimes I throw in greens just to feel like I’ve got it together. But the base? That sauce? It doesn’t need help.

Pasta Doesn’t Care What Shape It Is

Use whatever pasta you’ve got. I’ve done this with spaghetti, bowties, penne, even that weird bag of misfits that’s half elbow, half rotini. It always works.

Just cook it until it still has a little bite al dente, but I never call it that out loud, and save some of the pasta water before draining. That’s the trick. You can loosen the sauce, help it hug the noodles, fix it if it thickens up too much. That water’s not fancy, but it’s magic.

And no, don’t rinse the pasta. Ever. Toss it hot into the sauce and just stir it around. Give it a minute. Let it settle. You’ll know when it’s right.

Some nights I top it with cheese. Some nights I don’t. If there’s a lime lying around, I’ll use it. If not, no big deal.

It’s not a “perfect pasta dish.” It’s a Wednesday night pasta dish. It’s a “this is what I had, and it turned out kind of wonderful” dish.

And if that’s your vibe, you might also like my truffle pasta when you’re feeling cozy and a little indulgent, or my Marry Me Pasta when you want something that tastes like you worked harder than you did.

But this one? This one’s just honest food. No performance. Just dinner.

Final Thoughts (No Fancy Wrap-Up)

This pasta wasn’t planned. It wasn’t tested ten times or carefully styled. It just happened, on a tired night when all I had were tomatillos, pasta, and a blender.

And sometimes? That’s how the best stuff shows up in the kitchen.

It’s not perfect. It changes every time I make it. But that’s the beauty of it. It’s flexible. Forgiving. Real.

So if you’ve got a bag of tomatillos or a lonely can in the pantry, give this a shot. And if it turns out completely different than mine? Even better. That means it’s yours now.
