Introduction

Aglio e Olio (pronounced "AH-lyoh eh OH-lyoh") is one of Italy's most essential pasta dishes, originating from Naples. The name literally translates to "garlic and oil" - a perfect description of its two primary ingredients. Unlike many pasta recipes that rely on complex sauces or numerous components, this dish exemplifies how Italian cuisine often achieves its greatest heights through simplicity.

This vegan version stays true to the traditional preparation, as the original recipe is naturally plant-based. The magic happens when thinly sliced garlic slowly infuses into warm olive oil, creating a fragrant base that coats each strand of spaghetti. A careful touch of chili flakes adds warmth without overwhelming heat, while fresh parsley brings a necessary brightness to balance the richness of the oil.

What makes this dish particularly special is its reliance on technique rather than elaborate ingredients. The key lies in properly cooking the garlic to a golden state without letting it brown, which would introduce unwanted bitterness. Similarly, the pasta water - often overlooked in home cooking - plays a crucial role in creating the light, silky sauce that characterizes a proper Aglio e Olio.

This recipe includes a slight deviation from tradition with the addition of lemon juice, which adds a contemporary brightness that complements the classic flavors. While purists might skip this addition, it's an excellent example of how classic dishes can evolve while maintaining their essence. The entire dish comes together in roughly the time it takes to cook the pasta, making it an ideal choice for both weeknight dinners and last-minute entertaining.

Ingredients

Instructions

  1. Boil Water: Bring a large pot of water to a rolling boil.
  2. Season Water: Add a generous amount of salt (the water should taste like the sea).
  3. Cook Pasta: Add 100g (3.5 oz) spaghetti and cook until al dente, according to package instructions.
  4. Reserve Water: Before draining, reserve 1/4 cup of the pasta cooking water. Set aside.
  5. Prepare Oil: Heat 3 tablespoons of extra virgin olive oil in a large skillet over low heat.
  6. Cook Garlic: Add 4 thinly sliced garlic cloves and cook gently, stirring occasionally, until fragrant and golden (2–3 minutes). Watch carefully to avoid browning.
  7. Add Spice: Stir in 1/2 teaspoon of chili flakes and cook for 30 seconds to bloom the flavors.
  8. Combine Pasta: Add the cooked spaghetti to the skillet along with 2–3 tablespoons of the reserved pasta water.
  9. Create Sauce: Toss to coat the pasta evenly in the garlic oil, adding more pasta water as needed to create a silky, light sauce.
  10. Add Citrus: Stir in 1 tablespoon of freshly squeezed lemon juice and toss well.
  11. Check Seasoning: Taste and adjust the seasoning with salt if needed (the pasta water should already provide some saltiness).
  12. Add Herbs: Remove from heat and stir in 1–2 tablespoons of chopped parsley.
  13. Final Plating: Transfer to a plate and garnish with additional parsley if desired.
  14. Optional Garnish: For added texture and flavor, sprinkle with vegan parm or toasted breadcrumbs.

Recipe Notes

  • Pasta Texture: Be sure to cook the spaghetti al dente (slightly firm to the bite). Overcooking the pasta can make it too soft and affect the overall dish.
  • Adjusting the Heat: You can modify the level of spice by adjusting the amount of chili flakes. Start with less and add more if you like it spicier.
  • Lemon Juice: Freshly squeezed lemon juice adds a bright, tangy flavor. Avoid bottled lemon juice for the best taste.
  • Pasta Water: Don’t forget to reserve some pasta water before draining—it helps create a silky sauce that adheres well to the pasta.
  • Optional Toppings: Vegan parm or toasted breadcrumbs are great additions, but the dish is delicious even without them.
  • Storage: This dish is best served fresh. If you have leftovers, store them in an airtight container in the fridge for up to 2 days, but note the texture may change when reheated.
  • Doubling the Servings: To double the serving size, simply double the ingredients, including the pasta, olive oil, garlic, chili flakes, lemon juice, and parsley. You may need to use a larger skillet or cook in batches to ensure the garlic oil is evenly distributed. Also, be sure to reserve enough pasta water to create a smooth, silky sauce. The cooking times for the pasta and garlic oil should remain the same, but keep an eye on the heat to avoid overcooking the garlic.

Frequently Asked Questions

Yes, gluten-free pasta can be substituted, but keep in mind the cooking time may vary, so follow the package instructions.

Absolutely! If you prefer a milder version, simply omit the chili flakes or substitute them with a dash of black pepper for a gentle kick.

This dish is best enjoyed immediately after preparing it, as the pasta tends to absorb the sauce and lose its freshness if stored for too long. However, you can prep the garlic oil and reserve the pasta water in advance.

Basil, oregano, or thyme would be great alternatives. Fresh herbs will give a similar burst of flavor to finish the dish.

To make this recipe oil-free, you could use a light vegetable broth in place of olive oil. The flavor will be different but still enjoyable.
