Aglio-e-olio

What is Aglio e Olio?

Aglio e olio (Italian) means “garlic and oil.” It’s a classic, simple pasta dish where spaghetti is tossed with:

1. olive oil
2. garlic (gently cooked so it turns fragrant, not brown)
3. chili flakes
4. parsley
5. (often) a little lemon zest or pasta water to make it glossy and saucy

A vegan version swaps out any cheese (and skips butter/anchovies entirely).

Flavour profile

Overall: garlicky, peppery, chili-warm, herb-fresh, silky from olive oil + starchy pasta water.

1. Garlic: sweet-raw aroma becomes mellow and savory when gently sautéed
2. Chili flakes: adds heat and a little “smoky/spicy” edge
3. Olive oil: fruity, rounded, slightly peppery background
4. Parsley: bright, fresh, green finish
5. Pasta water: makes the sauce cling and taste more “buttery” (without dairy)

Vegan Nutrition (approx. per serving)

Assuming 1 serving = 1/4 of a 4-serving recipe (about about 3.5–4 oz / 100–120 g dry pasta equivalent per person), and using:

1. olive oil as listed below
2. no cheese
3. no added meat/fish

Approximate macros (varies with pasta brand/oil amount):

1. Calories: ~520–650 kcal
2. Carbohydrates: ~70–90 g
3. Fat: ~18–28 g (mostly monounsaturated from olive oil)
4. Protein: ~12–16 g
5. Fiber: ~4–8 g (depends on pasta type)

Micronutrients you’ll get:

1. Vitamin E and healthy fats from olive oil
2. Manganese (common in pasta/whole grains)
3. Garlic compounds (and antioxidant activity)
4. Potassium/folate (especially if using whole-wheat pasta)
5. Vitamin K / vitamin C in parsley

Detailed Vegan Recipe (serves 4)

Ingredients

1. 400 g (14 oz) spaghetti (vegan-friendly)
2. 1/2 cup (120 ml) extra-virgin olive oil
3. 6 cloves garlic, thinly sliced (or finely chopped)
4. 1/2–1 tsp chili flakes (adjust to taste)
5. 1/2 tsp salt, plus more for pasta water
6. Black pepper, to taste
7. 1/2 cup (10–15 g) fresh parsley, finely chopped
8. 1 tbsp lemon juice or zest of 1/2 lemon (optional but recommended)
9. 1/2–1 cup (120–240 ml) pasta cooking water (for emulsifying sauce)

Optional add-ins (still vegan)

1. 2–3 tbsp nutritional yeast (adds “cheesy” savory depth)
2. 1–2 tbsp capers or a handful of chopped olives
3. 1/2 tsp smoked paprika (subtle warmth, extra depth)

Step-by-step instructions

1) Cook the pasta

1. Bring a large pot of water to a boil.
2. Salt the water well (it should taste pleasantly salty—this seasons the pasta).
3. Cook spaghetti until al dente (usually 1–2 minutes less than package time).
4. Before draining, reserve at least 1 cup of pasta water.
5. Drain the pasta.

2) Make the garlic-chili oil (key step)

1. While pasta cooks, place a large pan on low to medium-low heat.
2. Add olive oil and let it warm gently.
3. Add sliced garlic and chili flakes.
4. Cook 2–4 minutes, stirring frequently.
5. Goal: garlic turns golden and fragrant, not brown.
6. If you see browning, lower heat and add a splash of pasta water to cool the pan.

3) Toss + emulsify into a sauce

1. Add drained pasta to the pan.
2. Toss well so each strand gets coated.
3. Add a few splashes of pasta water and keep tossing.
4. Continue until the sauce looks glossy and clings to the noodles.
5. Typically 1/2 to 1 cup pasta water depending on how saucy you like it.

4) Finish

1. Turn off heat (or keep it very low).
2. Stir in parsley.
3. Add lemon juice or zest if using.
4. Taste and adjust:
5. more salt (usually a little)
6. more chili
7. more black pepper

5) Serve

1. Serve hot with extra parsley and a drizzle of olive oil if desired.

Common mistakes (and fixes)

1. Garlic turns bitter/brown → heat was too high. Use low heat next time; slice thinner; toss quickly.
2. Too oily / not saucy → add more pasta water and toss longer to emulsify.
3. Not garlicky enough → slice garlic thin, and don’t let oil cool too much before adding garlic.

Quick “taste upgrade” (optional)

After tossing, add:

1. 1 tsp lemon zest + 1 tbsp lemon juice (brightens)
2. or 1–2 tbsp nutritional yeast (more umami)
