I figured pesto was just “green stuff blitzed with oil” — how hard could it be? My first attempt tasted like bitter grass swimming in greasy soup. No depth. No punch. Definitely not Gordon Ramsay level.
The breakthrough came when I learned Ramsay’s key moves: toast the nuts, control the oil flow, and stop blending before you turn it into green baby food.
Here’s how you actually get that fresh, creamy, sharp pesto you imagine tasting in a real kitchen.
Why This Works (And Where Most Go Wrong)
Pesto is about control. Most people flood the processor with oil too fast or over-blend into mush.
Gordon’s version hits hard because:
- He toasts the nuts — unlocking deeper nutty flavor.
- He blends dry ingredients first — better texture control.
- He slowly streams oil — for silky emulsification, not separation.
- He leaves a little grit — pesto should be rustic, not baby food.
Ingredients That Actually Matter
- Fresh Basil Leaves (3 cups) — No shortcuts. Wilted or dried basil = dead pesto.
- Chopped Walnuts (1 ½ cups) — Toast them lightly. Raw walnuts taste flat.
- Garlic Cloves (4, peeled) — Fresh, not jarred garlic.
- Grated Parmesan (1/4 cup) — Real Parmigiano-Reggiano if you can.
- Olive Oil (1 cup) — Good-quality extra virgin.
- Salt and Pepper — Always to taste after blending.
Optional but Tested Swaps
- Swap half the walnuts with pine nuts for a classic twist.
- Add a squeeze of lemon if you want a brighter, punchier pesto.
How To Make Gordon Ramsay Pesto Sauce
First, prep everything. Wash the basil and toast the walnuts until just fragrant — about 3 minutes on a dry pan, medium heat.
Into the food processor: add 75g basil leaves, 180g toasted walnuts, 4 peeled garlic cloves, and 30g Parmesan. Pulse until everything is finely chopped but still has texture.
Now, with the processor running, slowly drizzle in 240ml olive oil. Go steady — too fast and you’ll break the emulsion.
Stop and scrape down the sides if needed. Pulse again until creamy but slightly coarse. You’re aiming for a thick, spoonable sauce — not a smoothie.
Taste. Season with salt and pepper. Blend one last quick pulse.
Use immediately, or store properly (I’ll cover that below).

What Gordon Ramsay Says About This Dish
“Freshness is key. If you lose that bright green color, you’ve killed it.”
— In testing, I found over-blending or using old basil immediately dulled the color.
“Don’t be shy with seasoning. Basil is a bully — you need to season hard.”
— The pesto always needed a good pinch of salt post-blend.
“Stream your oil—don’t dump it.”
— When I rushed it, the pesto split into a greasy mess.
What I Got Wrong (And How I Fixed It)
- Over-blending: I pureed the first batch into green goo. Now I pulse gently, just until combined.
- Raw walnuts: Skipped toasting once—pesto tasted bland and chalky. Always toast.
- Oil dump: I dumped all the oil in one go. Huge mistake. Slow streaming fixed the texture.
Variations That Actually Hold Up
- Spinach Pesto: Swap half the basil for baby spinach for a milder, softer pesto.
- Almond Pesto: Use toasted almonds instead of walnuts for a sweeter nutty profile.
- Vegan Pesto: Drop the cheese and add a tablespoon of nutritional yeast.
Pro Tips That Change The Game
- Chill Your Blade: Cold food processor blades help keep the basil from bruising.
- Ice Water Trick: Add 1 tablespoon of ice water at the end to brighten color if your pesto starts to darken.
- Storage Oil Cap: When storing, pour a thin layer of olive oil on top to block air and keep it greener longer.
Storage + Leftover Moves
- Refrigerate: Store in a sealed container up to 5 days. Always stir before using.
- Freeze: Freeze in ice cube trays, then transfer to bags. Holds for 3 months easily.
- Use It Up: Swirl into soups, spread on sandwiches, or toss with roasted veggies.
FAQs — Covering Search Intent
Q: Can I use a blender instead of a food processor?
A: You can, but it’s harder to control texture. Pulse gently.
Q: Why is Gordon Ramsay’s pesto so vibrant green?
A: Fresh basil, cold equipment, and minimal blending. Heat kills the color fast.
Q: Can I swap walnuts for pine nuts?
A: Absolutely. It’s more traditional but also pricier.
Q: Should pesto taste salty?
A: Yes—it needs aggressive seasoning to stand up to pasta or bread.
Q: How can I make pesto creamy without cheese?
A: Toasted nuts + slow oil stream + optional avocado boost.
