The smell of garlic sizzling in olive oil hits different when you're making Instant Pot spaghetti aglio e olio on a random Tuesday night—especially if your usual is Instant Pot spaghetti.

I stumbled on this one by accident, honestly. Sarah was working late grading papers, the kids were complaining they were starving, and I had pasta, garlic, and not much else in the pantry.

Instant Pot spaghetti aglio e olio with garlic, olive oil, parsley, and red pepper flakes.

Why This Instant Pot Spaghetti Aglio e Olio Hits

Turns out, you don’t need fancy ingredients to make something that tastes like you actually tried. The pasta cooks right in the pot with everything else, soaking up all that garlicky, spicy flavor.

Jake ate two bowls without asking what was in it, which is basically a five-star review in this house.

Here’s why this one sticks around:

Done in 20 minutes, total
Garlic and red pepper flakes do the work
One pot, minimal cleanup
Traditional aglio e olio recipe made stupid simple
Comfort food without the fuss

I mean, it’s not fancy. But it’s good, and that’s what matters on a weeknight

What You Need for This Italian Dish

This Instant Pot spaghetti aglio e olio is all about keeping it simple with garlic, olive oil, and a little heat.

You’re working with maybe five or six things, and most of them you probably already have sitting around.

  • Spaghetti noodles : regular dried pasta works perfectly, nothing fancy needed
  • Garlic cloves : fresh is the move here, minced nice and fine
  • Olive oil : use something decent, you’ll taste it
  • Red pepper flakes : adds that little kick without going overboard

The best part? Everything cooks together, so you’re not babysitting a pot on the stove.

How to Make Instant Pot Spaghetti Aglio e Olio (Quick Version)

Making Instant Pot spaghetti aglio e olio is about as straightforward as pasta gets, and the garlic does most of the talking.

You’re looking at maybe three minutes of prep, then the pot handles the rest.

  1. Turn the Instant Pot to sauté mode and add the oil and butter.
  2. Toss in the minced garlic and stir it around for about a minute until it smells amazing.
  3. Add the water, salt, pepper, red pepper flakes, and dried parsley.
  4. Break the spaghetti in half and lay it in the pot, making sure it’s mostly submerged.
  5. Seal the lid, set to high pressure for 8 minutes, then quick release when it beeps.
  6. Stir everything together, add the Parmesan, and adjust the seasoning if needed.

First time I made it, I thought the pasta would stick together. Nope, came out perfect.

If you want to switch things up, there are a few ways to go.

Ways to Tweak Your Spicy Aglio e Olio in Instant Pot

This Instant Pot spaghetti aglio e olio is flexible enough to handle whatever you’ve got on hand or whatever sounds good. Or go creamy with Instant Pot spaghetti carbonara.

With Extra Garlic

Look, some people think six cloves is enough. I’m not one of them. Add a couple more if you want that punch, just don’t burn it in the sauté step. Sarah always says I go overboard with garlic, but she still finishes her plate.

Lemon Zest Finish

After it’s done, grate some lemon zest over the top and squeeze in a little juice. Brightens the whole thing up, kind of cuts through the richness. Sophie actually liked it better this way, which shocked me.

With Crispy Breadcrumbs

Toast some panko in a skillet with a little olive oil until golden, then sprinkle it on top before serving. Adds a nice crunch, makes it feel a little more special without much effort.

You can also toss in some frozen peas or spinach right before the quick release if you want to sneak in some greens. Or go veggie-forward with Instant Pot spaghetti primavera.

What to Serve with Garlic Spaghetti in Pressure Cooker

This Instant Pot spaghetti aglio e olio is filling on its own, but sometimes you want a little something on the side.

At home, we usually keep it simple with a quick salad or some bread to soak up the garlicky oil at the bottom of the bowl.

Simple Arugula Salad

Toss some arugula with lemon juice, olive oil, and shaved Parmesan. Takes two minutes, adds a peppery bite that balances out the pasta. Jake won’t touch it, but Sarah and I split it.

Garlic Bread

I know, more garlic. But come on, if you’re already going all in, might as well commit. I just buy the frozen kind from H-E-B, throw it in the oven while the pasta’s cooking.

Roasted Broccoli

If you’ve got time, toss some broccoli florets with olive oil and salt, roast them at 425°F for about 20 minutes. Sophie will pick around it, but at least it’s there.

Leftovers keep pretty well, which is good because I always make too much. Craving meat sauce? Instant Pot spaghetti Bolognese delivers.

Keeping Your Instant Pot Spaghetti Aglio e Olio Fresh

This Instant Pot spaghetti aglio e olio holds up better than you’d think, especially if you store it right.

Whether you’re packing lunch for tomorrow or trying to stretch dinner into the next day, here’s what actually works.

Storage

  • At room temperature: Good for about 2 hours max if you’re serving it at a gathering, then get it in the fridge.
  • In the fridge: Transfer to an airtight container and it’ll last 3-4 days. The garlic flavor gets stronger over time, which isn’t a bad thing.
  • In the freezer: Honestly, I don’t freeze this one. The pasta texture gets weird when you thaw it. Better to just make a fresh batch.

Reheating

Microwave works fine. Add a splash of water or broth, cover it, and heat in 1-minute bursts, stirring between each round. If you’re using a skillet, toss it over medium heat with a little olive oil and it’ll crisp up nicely on the edges.

Anti-waste tip

Leftover pasta? Toss it in a hot skillet with a beaten egg and some cheese, let it set like a frittata. Totally different meal, nothing wasted.

Got questions? Yeah, I had a bunch too when I first tried this.

Common Questions About This Recipe

Can I use fresh pasta instead of dried spaghetti?

Fresh pasta cooks way faster, so you’d need to cut the pressure time to like 2 minutes. Honestly, dried works better here.

What’s the best olive oil for aglio e olio?

Use something you’d actually want to taste. Doesn’t need to be fancy, but skip the bargain bin stuff. I usually grab whatever’s on sale at H-E-B that looks decent.

How do I make aglio e olio less spicy?

Just cut back on the red pepper flakes. Start with a quarter teaspoon, taste it, add more if you want. You can always add heat, can’t take it away.

Why did my quick aglio e olio pasta turn out mushy?

Happened to me once too. Usually means you overcooked it or used too much water. Stick to the times and don’t add extra liquid.

This Instant Pot Spaghetti Aglio e Olio is a quick and easy pasta dish that combines the rich flavors of garlic, olive oil, and red pepper flakes. Perfect for a weeknight dinner, this recipe requires minimal ingredients and effort, yet delivers a comforting and satisfying meal.

Equipment

  • Instant Pot
  • Knife
  • Measuring cups

Ingredients

  • 2 tablespoons olive oil
  • 1 tablespoon unsalted butter
  • 6 large garlic cloves minced
  • 2 cups water
  • ¾–1 teaspoon salt adjusted to taste
  • ½ teaspoon crushed red pepper flakes
  • ½ teaspoon ground black pepper
  • 1 teaspoon dried parsley
  • 8 ounces spaghetti noodles
  • ½ cup grated Parmesan cheese

Instructions

  • Turn the Instant Pot to sauté mode and add the olive oil and butter.
  • Once the butter melts, add the minced garlic and stir for about a minute until it’s fragrant but not browned.
  • Pour in the water, then add the salt, red pepper flakes, black pepper, and dried parsley.
  • Break the spaghetti noodles in half and lay them in the pot, pressing them down gently so they’re mostly covered by the liquid.
  • Cancel the sauté mode, seal the lid, set the valve to sealing, and cook on high pressure for 8 minutes.
  • When the timer beeps, carefully quick release the pressure by turning the valve to venting.
  • Open the lid, stir everything together to coat the pasta in the garlicky liquid, then stir in the Parmesan cheese.
  • Taste and adjust the salt or add more red pepper flakes if you want it spicier.

Notes

  • If you like it extra garlicky, bump it up to 8 or 9 cloves. The garlic mellows out a bit during pressure cooking.
  • You can swap the dried parsley for fresh if you’ve got it, just toss it in at the end instead.
  • One time I added a handful of baby spinach right before serving and it wilted perfectly into the pasta.
  • At home, Jake likes his with extra Parmesan and Sophie picks out the garlic pieces, but she still eats it.
