Tips for choosing, storing and cooking prawns so they stay tender and soak up all that garlic and oil

I first had gambas al ajillo years ago on a trip to Spain, and I’ve ordered it in pretty much every tapas bar I’ve visited since. It always amazes me how so few simple, fresh ingredients can combine to make something this tasty and vibrant.

Prawns, garlic, good olive oil, a little chilli and a squeeze of lemon. That’s really all it takes. This is my easy version, baked rather than fried, so there’s even less to fuss over.

What is gambas al ajillo?

Gambas al ajillo simply means “prawns with garlic.” It’s one of the most popular tapas dishes in Spain, and you’ll find it on menus in coastal towns and big cities alike, usually served sizzling in a little terracotta dish with crusty bread for mopping up the oil.

Traditionally it’s cooked on the stovetop in olive oil infused with garlic and chilli. My version bakes in the oven, which keeps it hands-off and means you can’t overcrowd the pan or burn the garlic while you’re not looking.

How do you make Spanish garlic prawns?

Mix olive oil with paprika, salt and pepper. Pour it over raw king prawns with garlic, chilli and lemon juice in a baking dish, then bake at 180°C until the prawns turn pink and just cooked through. Scatter with parsley and serve with crusty bread. That’s the whole thing.

The oil does the heavy lifting here. As it bakes, it takes on the garlic, chilli and paprika, turning into the fragrant, savoury sauce that makes this dish what it is.

Tips for the best Spanish garlic prawns

Use good olive oil. The oil becomes the sauce here, so a decent extra virgin olive oil makes a real difference to the flavour.
Don’t overcook the prawns. They’re done the moment they turn pink and opaque. Any longer and they turn rubbery.
Slice the garlic thinly. Thin, even slices infuse the oil beautifully without catching and turning bitter.
Serve it hot. Gambas al ajillo is best straight from the oven while the oil is still sizzling.
Have bread ready. Crusty bread for soaking up the garlicky oil is non-negotiable. It’s the best part.

Ingredients

A short list of fresh, simple ingredients is all you need.

100 ml olive oil
½ teaspoon paprika
Pinch of salt and pepper
600 g raw king prawns, deveined
Juice of one lemon
4 cloves garlic, thinly sliced
1 red chilli, finely chopped
Handful of fresh parsley, chopped

How to make Spanish garlic prawns

1. Preheat the oven. Set it to 180°C.

2. Mix the oil. In a bowl, mix the olive oil, paprika, salt and pepper together, then set to one side.

3. Prepare the prawns. In a baking dish or ceramic dish, add the prawns and squeeze the lemon juice over the top. Add the garlic and chilli. Pour the seasoned olive oil over the top and combine everything well.

4. Bake. Bake in the oven until the prawns are pink and just cooked through.

5. Serve. Scatter over the fresh parsley and serve straight away, with plenty of crusty bread for the oil.

Common mistakes to avoid

Overcooking the prawns. This is the big one. Prawns cook fast and turn rubbery if left too long. Pull them as soon as they’re pink and opaque.
Burning the garlic. Burnt garlic turns bitter and spoils the oil. Thin slices and a steady oven temperature keep it sweet and fragrant.
Skimping on the oil. The oil is the sauce, not just the cooking fat. You want enough to spoon over bread.
Using cheap, flavourless oil. Since the oil carries the whole dish, a good extra virgin olive oil is worth it.
Serving it lukewarm. This dish is all about that hot, sizzling arrival. Get it to the table quickly.

Tips, variations and substitutions

Add a splash of sherry. A little dry sherry or white wine stirred in gives it an extra layer of authentic Spanish flavour.
Adjust the heat. Use more or less chilli to suit your taste, or dried chilli flakes if you don’t have fresh.
Smoked paprika. Swap regular paprika for smoked (pimentón) for a deeper, smokier note.
Prawn size. King prawns work brilliantly, but larger tiger prawns are lovely too. Just allow a little more cooking time.
Keep the shells on. Cooking shell-on prawns adds even more flavour, though they’re messier to eat.

Serving suggestions

Serve gambas al ajillo the way they do in Spain, hot from the oven with lots of crusty bread to soak up the garlicky oil. That oil is far too good to leave behind.

It works beautifully as part of a tapas spread with a few other small plates, a glass of cold white wine or a chilled fino sherry, and some olives on the side. It also makes a lovely light starter before a bigger meal.

Frequently asked questions

What does gambas al ajillo mean?
It’s Spanish for “prawns with garlic.” It’s a classic tapas dish of prawns cooked in olive oil infused with garlic and chilli, served sizzling with bread.

How do you know when prawns are cooked?
Prawns are done when they turn pink and opaque and curl into a loose C shape. They cook quickly, so take them out as soon as they’re there to keep them tender.

What prawns are best for gambas al ajillo?
Raw king prawns are ideal. Larger tiger prawns work well too. Using raw rather than pre-cooked prawns is important, as pre-cooked ones turn rubbery when reheated.

What do you serve with Spanish garlic prawns?
Crusty bread is essential for soaking up the oil. Beyond that, they’re perfect as part of a tapas spread with a glass of white wine or dry sherry.

Can I use frozen prawns?
Yes. Defrost them fully first and pat them dry so they don’t release water into the dish, which would dilute the oil.

Is gambas al ajillo spicy?
It has a gentle warmth from the chilli rather than real heat, and you control it. Use more chilli for a kick or leave it out for a milder dish.
