Ingredients

  • 400 g pasta (your choice of shape)
  • 2 tbsp extra-virgin olive oil
  • 3 cloves garlic, minced
  • 1 medium onion, diced
  • 0.5 tsp salt
  • 0.25 tsp freshly ground black pepper

Instructions

  1. 1

    Cook the Pasta

    Bring a large pot of salted water to a rolling boil. Cook pasta according to package directions until al dente. Reserve 1 cup of pasta water before draining.

  2. 2

    Prepare the Base

    While pasta cooks, heat olive oil in a large skillet over medium heat. Add garlic and cook until fragrant, about 30 seconds.

  3. 3

    Build the Sauce

    Add the main sauce ingredients to the skillet and cook, stirring occasionally, until the flavours meld together, about 3-5 minutes.

  4. 4

    Combine

    Add the drained pasta to the sauce and toss vigorously, adding pasta water as needed to achieve a silky consistency that coats every strand.

  5. 5

    Serve

    Plate immediately and garnish with fresh herbs and freshly grated cheese. Serve hot with crusty bread on the side.

Chef's Notes

I always undercook the pasta by 2 minutes before baking — it finishes cooking in the oven and won't turn mushy.

About This Recipe

There's something quietly brilliant about a dish that asks you to do almost nothing and delivers comfort anyway. This garlic and olive oil pasta — known in Italian kitchens as aglio e olio — has been a Canadian weeknight lifeline since before anyone bothered to put it on a blog. You start with pasta, a splash of olive oil, and a handful of garlic cloves, and somehow it all comes together into something silky and deeply satisfying.

The magic lives in the starchy pasta water, which you reserve before draining and fold back into the skillet. That liquid gold emulsifies with the oil and garlic to coat every strand, turning humble pantry staples into dinner that tastes like someone cared. It's fast enough for a Tuesday, elegant enough for guests, and forgiving enough that even a tired cook can pull it off.

Tips for the Best Tuna Noodle Casserole

Saliez généreusement votre eau de cuisson — elle doit avoir le goût de la mer — car une fois les pâtes dans la poêle, il n'y a plus de place pour corriger l'assaisonnement. Cuisez les pâtes une minute de moins que le temps indiqué, puisqu'elles continueront à cuire dans la sauce, et gardez la chaleur modérée quand vous faites revenir l'ail pour éviter qu'il ne devienne amer. Remuez vigoureusement les pâtes égouttées dans la poêle, en ajoutant l'eau de cuisson par petites quantités jusqu'à ce que la sauce adhère à chaque brin.

What to Serve With It

This dish shines alongside a crisp green salad dressed with lemon and good olive oil, or a simple arugula tossed with shaved Parmesan. In Canada, I often serve it with a loaf of crusty French bread from the local bakery to soak up every last drop of sauce, and a glass of Pinot Grigio or a crisp local lager rounds out the table nicely.

Storage & Reheating

Leftovers keep in the fridge for three days in an airtight container, though the pasta will absorb some sauce overnight — that's normal. Reheat gently in a skillet with a splash of water or broth, tossing over low heat until warmed through. You can freeze portions for up to two months, but expect a slightly softer texture once thawed and reheated.

Frequently Asked Questions

Can I add protein to this dish?+

Absolutely — grilled chicken, shrimp, or crispy pancetta all work beautifully. Add them during the last minute of cooking so they stay tender and don't dry out.

Is the reserved pasta water really that important?+

Yes, it's the secret to getting that silky, clingy sauce. The starch helps the oil and garlic bind into a cohesive coating instead of pooling separately at the bottom of the bowl.

What kind of pasta works best here?+

Long strands like spaghetti or linguine are traditional, but any shape works. Short pastas like penne or fusilli hold sauce well and make this dish even easier to eat.

How do I keep the garlic from burning?+

Keep the heat at medium and stir frequently. Garlic goes from fragrant to bitter in seconds, so watch it closely and remove the skillet from the burner if it starts to colour too quickly.

Can I make this ahead for meal prep?+

It's best eaten fresh, but you can prep the garlic and sauce base ahead and toss with cooked pasta just before serving. The texture is noticeably better when the pasta hasn't sat in the sauce for hours.

Tips & Tricks

  • Always salt your pasta water generously — it should taste like the sea.
  • Reserve a cup of starchy pasta water before draining. It's liquid gold for emulsifying sauces.
  • Cook pasta 1 minute less than the package says if finishing it in the sauce.
