15-Minute Spaghetti Aglio Olio
This spaghetti aglio olio is the simplest pasta you’ll make all week, ready in 15 minutes with just 5 ingredients. It’s the kind of dish that feels like a secret weapon for busy nights.
Garlic sizzled gently in olive oil, a pinch of chilli flakes, and a tangle of al dente spaghetti. It’s straightforward, fast, and exactly what you want on a Tuesday night.
Why This Aglio Olio Works
Plain ingredients can add up to something greater than the sum of their parts. The garlic infuses the oil slowly, turning it golden and sweet without a hint of bitterness.
A splash of starchy pasta water binds everything into a light, glossy sauce that coats every strand. And because it comes together in one skillet while the pasta boils, there’s very little to clean up.
Ingredients
- 1 lb spaghetti: or another long pasta like linguine
- 6 cloves garlic, thinly sliced: slicing gives you soft, sweet garlic pieces, not burnt bits
- ½ cup extra-virgin olive oil: use the good stuff, it carries the whole dish
- ½ tsp red pepper flakes: more or less depending on your heat preference
- ⅓ cup chopped fresh parsley: flat-leaf holds up better than curly
- Salt: for the pasta water and a final sprinkle
Variations / Substitutions
- Gluten-free: use a good gluten-free spaghetti, but reduce the reserved pasta water by a couple tablespoons since it releases more starch
- Add protein: sauté a handful of shrimp in the garlic oil right after the garlic turns golden, then remove before adding the pasta
- Extra brightness: a squeeze of lemon juice at the end lifts everything
- Cheese: a shower of grated Parmesan works, though purists might argue

How To Make Spaghetti Aglio Olio
Step 1: Cook the Spaghetti
Bring a large pot of water to a boil and salt it generously until it tastes like the sea. Add the 1 lb spaghetti and cook for about 8 minutes, which is 1 minute less than the package says for al dente. Before draining, scoop out at least 1 cup of that cloudy pasta water and set it aside, then drain the spaghetti.
You’ll see the water turn milky as the starch releases. That starch is exactly what will pull the sauce together later, so do not skip saving it. The pasta will finish cooking in the skillet and soak up all the flavour.
Step 2: Sizzle the Garlic
While the spaghetti cooks, place a large skillet on medium-low heat and add the ½ cup olive oil. Drop in the 6 sliced garlic cloves and the ½ tsp red pepper flakes. Let them sizzle gently, stirring now and then, for 3 to 4 minutes. You want the garlic just pale gold and fragrant, not browned.
The kitchen will fill with a mellow garlic smell. If the garlic starts to darken too fast, simply pull the pan off the heat for a few seconds. Burnt garlic turns bitter and you’ll have to start over, so keep the heat low and your eyes on the pan.
Step 3: Toss and Serve
Tip the drained spaghetti straight into the skillet with the garlic oil. Toss everything together with tongs, then pour in about ⅓ cup of the reserved pasta water. Keep tossing vigorously for 1 to 2 minutes, adding another splash of water if the pasta looks dry, until a silky, emulsified sauce clings to every strand. Take the pan off the heat, fold in the ⅓ cup chopped parsley, and taste for salt.
The sauce should look glossy and pale golden, not greasy. Pile the pasta into bowls right away and scatter a little extra parsley on top. Serve hot, while the strands are still slippery and the garlic pieces are soft.
A Few Notes Before You Start
- Salt the water properly. Salty water is the only chance to season the pasta from within, so be generous.
- If your garlic starts to colour too quickly, slide the skillet off the burner and let the residual heat finish the job. You can always return it to the heat if needed.
- This dish waits for no one. Have everyone at the table before you toss the pasta with the sauce, because it’s at its best the moment it’s done.
Keeping Leftover Pasta Fresh
- Refrigerate: store any leftovers in an airtight container for up to 2 days.
- Reheating: warm the pasta gently in a skillet with a splash of water to loosen the sauce. A quick turn in the microwave works too, but the texture won’t be quite as silky.
What To Serve With Spaghetti Aglio Olio
A crisp green salad with a sharp lemon vinaigrette cuts through the richness of the oil and garlic. Garlic bread is the obvious match because more garlic is never wrong, and the crunch gives the meal some texture. If you want something heartier, sauté a few shrimp right in the garlic oil and pile them on top.
Frequently Asked Questions
Can I use whole wheat or gluten-free pasta?
Yes, you can, but the texture will be a bit chewier and the sauce may not cling the same way. Gluten-free pasta tends to release extra starch as it cooks, so start with less pasta water when you toss everything together.
What if my garlic burns?
Burnt garlic turns acrid and bitter. If it happens, the best fix is to start fresh. The whole dish relies on that sweet, mellow garlic flavour, so it’s worth the five minutes.
Is spaghetti aglio olio vegan?
Yes, it’s naturally vegan as long as your dried pasta is made without eggs. The sauce is just olive oil, garlic, chilli, and parsley.
Can I use dried parsley?
Fresh parsley gives a bright, clean finish that contrasts with the warm oil. Dried parsley won’t soften into the sauce the same way, so I’d leave it out rather than substitute.
