What are garlic shrimp?
Garlic shrimp (gambas al ajillo) is one of the most iconic tapas in Spanish cuisine, a dish that with just four ingredients —fresh shrimp, garlic, chili, and extra virgin olive oil— achieves an explosive result in flavor. It consists of peeled shrimp briefly sautéed in abundant olive oil flavored with golden garlic slices and a spicy touch of chili, all served bubbling in an earthenware casserole that retains heat and allows you to dip bread until the last drop.
What makes this dish special is its deceptive simplicity. With so few ingredients, the quality of each is fundamental: shrimp that taste of the sea, a fruity olive oil, fresh and juicy garlic, and a chili that adds spice without dominating. The technique is equally crucial: the oil must be hot but not smoking, the garlic must be browned without burning, and the shrimp must be cooked for just a couple of minutes to be tender and juicy.
At Bacalalo, we are passionate about seafood prepared with respect for tradition. Garlic shrimp perfectly embody this philosophy: excellent raw material, simple technique, and extraordinary results. In our gourmet preserves, you will find seafood of the same quality that this recipe deserves.
History and origin of garlic shrimp
The origin of garlic shrimp dates back to the taverns and inns of Castilla-La Mancha, where garlic and olive oil were the pillars of popular cuisine. Although today we associate this dish with the Mediterranean coast, its birth is more linked to the Castilian tradition of cooking with abundant garlic and oil, a technique applied to all kinds of ingredients: mushrooms, snails, potatoes, and, of course, shrimp when they arrived from the coast.
In the 1950s and 1960s, with the tourism boom and the expansion of tapas bars throughout Spain, garlic shrimp became a universal classic. Its quick preparation, spectacular presentation—served sizzling in a small earthenware dish—and irresistible flavor transformed it into the essential tapa of any self-respecting bar. Curiously, it reached its maximum popularity in Madrid, far from the sea, in the traditional central bars where it was served as an appetizer before meals.
The influence of this dish transcends Spanish borders. In the United States, Spanish-style garlic shrimp have become a star dish in restaurants across the country. In Portugal, a similar version called gambas com alho is equally popular. And in Latin America, especially in Mexico and Argentina, garlic shrimp are a regular part of seafood restaurant menus.
The earthenware casserole is not merely an aesthetic detail: the ceramic retains heat exceptionally well, keeping the oil bubbling for several minutes after it leaves the heat. This allows the shrimp to continue cooking gently as they arrive at the table, and for the diner to enjoy that visual and auditory effect that is an essential part of the experience. Traditional casseroles from Bailén (Jaén) or Totana (Murcia) are still preferred by professionals, although any refractory earthenware casserole performs its function perfectly.
Ingredients for garlic shrimp (4 servings)
Main ingredients
- 500 g peeled shrimp (fresh or quality frozen)
- 8-10 large garlic cloves, peeled and thinly sliced
- 2 dried chilies (or 1 dried cayenne pepper, broken)
- 150 ml mild extra virgin olive oil
- 2 tablespoons brandy or fine Jerez wine (optional but recommended)
- 1 teaspoon sweet paprika from La Vera (optional)
- Fresh chopped parsley for serving
- Sea salt to taste
Required utensils
- Individual earthenware casserole or large cast-iron skillet
- Crusty baguette for serving
The choice of shrimp is key: Huelva white shrimp are the most prized for their sweet flavor and firm texture, although Palamós red shrimp or Sanlúcar prawns also yield excellent results. If using frozen shrimp, make sure they are completely defrosted and thoroughly dried with paper towels before cooking; any residual moisture will cause the oil to splatter and the shrimp to steam in their own liquid instead of sautéing.

Step-by-step preparation
Step 1: Prepare the shrimp
If the shrimp are frozen, thaw them in the refrigerator overnight or under a gentle stream of cold water for 15 minutes. Peel them completely, also removing the intestinal vein (the black thread on the back) with the tip of a knife or a toothpick. Dry them thoroughly with paper towels and season lightly with salt and pepper. Reserve the shells to make a fumet if desired.
Step 2: Slice the garlic
Peel the garlic cloves and slice them thinly and uniformly, about 2 millimeters thick. Uniformity is important so they brown evenly. Do not use a garlic press or chop the garlic too finely: whole slices provide better texture and their browning is easier to control. Some recipes lightly crush the garlic with the side of a knife before slicing; this releases more essential oils and enhances the flavor.
Step 3: Heat the oil
Pour the olive oil into the earthenware casserole or skillet and heat it over medium heat. The oil should be hot but not smoking: if you drop a slice of garlic in and it bubbles gently, the temperature is correct (approximately 140-150 °C). If it smokes, remove it from the heat and let it cool slightly. With an earthenware casserole, heat gradually from cold to prevent cracking due to thermal shock.
Step 4: Brown the garlic and chili
Add the sliced garlic to the oil and the chilies, broken in half (remove the seeds if you don't want too much spice). Cook over medium-low heat, stirring frequently, for 1-2 minutes, until the garlic is light golden. This is the most delicate moment: the garlic goes from golden to burnt in a matter of seconds, and burnt garlic ruins the entire dish with a bitter, unrecoverable taste. Maintain constant attention and stir continuously.
Step 5: Add the shrimp
Increase the heat to medium-high and add the shrimp all at once, spreading them in a single layer. Sauté for 1 minute per side, without moving too much: we want them to brown lightly, not steam. The shrimp are ready when they turn pink and curl slightly. Do not cook them for more than 2-3 minutes in total or they will become rubbery and dry.
Step 6: The touch of brandy (optional)
Remove the casserole from the heat momentarily, add the brandy or fine wine, and return to the heat. The alcohol will briefly ignite (flambé) if you use a gas stove, burning off in a few seconds. If using an electric hob, simply let the alcohol evaporate for 30 seconds. Brandy adds a depth of flavor and a toasted aroma that significantly elevates the dish. Sprinkle the paprika if using, stir quickly (don't let the paprika burn), and remove from heat.
Step 7: Serve immediately
Sprinkle fresh chopped parsley on top and bring the casserole directly to the table. Garlic shrimp are served sizzling, with the oil still crackling. Serve them with plenty of crusty bread to dip in that golden, aromatic oil that is the essence of the dish. Don't wait: this dish is best enjoyed at its exact point, freshly made.
Tips for perfect garlic shrimp
After years of preparing this dish at Bacalalo, we have learned some secrets that make the difference between good garlic shrimp and extraordinary ones:
- Preheated earthenware casserole: Always start with a cold casserole and gradually increase the temperature. Ceramic retains heat much better than metal, which keeps the shrimp bubbling until the last bite.
- Dry shrimp: This is perhaps the most important trick. Wet shrimp release water that lowers the oil temperature and steams them instead of sautéing. Dry them meticulously with paper towels.
- Golden, never burnt garlic: The garlic should be blond, with a light golden hue. If it darkens too much, remove it and start over; the bitter taste of burnt garlic contaminates the entire dish.
- Plenty of oil: Don't skimp on oil. Garlic shrimp are essentially shrimp confit in flavored oil. That oil is as much a protagonist as the shrimp themselves.
- Don't overcrowd the casserole: Shrimp need space to sauté. If they are crowded, they will release liquid and steam. It's better to cook in two batches than to overcrowd.
- Just the right time: 2-3 minutes of cooking is all the shrimp need. The residual cooking in the hot oil of the casserole will finish them off as they arrive at the table.
- Salt at the end: If you add salt too early, the shrimp will release liquid. Season just before serving or let each diner adjust to their taste.
Variations and creative versions
Garlic shrimp with mushrooms
Add 150 g of sliced mushrooms or porcini to the oil before the shrimp, sautéing them for 3-4 minutes until golden. The mushrooms absorb the garlic-flavored oil and provide an extraordinary umami note that complements the sweetness of the shrimp.
Garlic shrimp with Padrón peppers
Fry a handful of whole Padrón peppers in the oil before adding the garlic. When they are blistered and tender, remove them, prepare the shrimp normally, and serve everything together. The combination of slightly bitter peppers with sweet shrimp and spicy garlic is a festival of flavors.
Garlic shrimp with prawns
Substitute shrimp with prawns or combine them. Prawns, being larger, need an extra minute of cooking. Butterfly them along the back so they cook evenly and absorb the oil's flavor better.
Version with peas and asparagus
Add tender peas and wild asparagus tips to the oil two minutes before the shrimp. This springtime version adds color, texture, and a vegetable touch that contrasts magnificently with the seafood.
Basque-style garlic shrimp (with piparras)
Substitute the chili with piparras (pickled chilies from the Basque Country), which provide a milder spice and a very pleasant acidic touch. This version is ideal for those who prefer a less spicy but equally aromatic dish.
Pairing: wines and accompaniments
Pairing garlic shrimp requires a wine that can compete with the intensity of garlic and chili without overwhelming the delicacy of the shrimp:
- Albariño (Rías Baixas): The fresh acidity and citrus notes of Albariño cut through the richness of the oil and highlight the marine flavor of the shrimp. It is the classic and reliable pairing.
- Manzanilla de Sanlúcar: Dry, saline, with hints of almond. Manzanilla provides a savoriness that dialogues with the sea of the shrimp. It is the pairing of traditional Andalusian bars.
- Txakoli: Slightly sparkling, very fresh, and with a vibrant acidity that cleanses the palate between bites. Ideal for serving well chilled in summer.
- Verdejo (Rueda): Aromatic, with herbaceous notes that complement the garlic and parsley of the dish.
- Craft Pilsner-style beer: For those who prefer beer, a cold Pilsner, with its subtle bitterness and refreshing carbonation, is an excellent pairing.
In our wines and beverages section, you will find selected options that magnificently accompany this and other seafood recipes.
As an accompaniment, bread is indispensable: a crusty baguette or a crunchy crystal bread to soak up that golden oil. Thinly cut french fries or a green salad dressed with lemon complete an informal and unforgettable dinner.
Nutritional value of garlic shrimp
Shrimp are an excellent source of high-quality protein and low in calories. A serving of garlic shrimp (about 125 g of peeled shrimp with their oil) provides approximately:
- Calories: 320-380 kcal (mostly from olive oil)
- Proteins: 22-25 g
- Fats: 25-30 g (mainly monounsaturated fats from olive oil)
- Carbohydrates: 2-3 g
- Iodine, zinc, selenium, and phosphorus: abundant minerals in shrimp
- Vitamin B12: one serving covers more than 100% of the recommended daily intake
Garlic, for its part, provides sulfur compounds such as allicin, recognized for its antibacterial, anti-inflammatory, and cardioprotective properties. Extra virgin olive oil, a pillar of the Mediterranean diet, completes a dish that, despite its generous fat content, fits perfectly into a healthy and balanced diet.

Frequently Asked Questions
Can I use frozen shrimp for gambas al ajillo?
Yes, frozen shrimp work perfectly as long as you thaw them completely and pat them very dry with paper towels before cooking. Quality frozen shrimp, especially those frozen on the boat right after being caught, can even be fresher than shrimp from the counter. The key is to remove all moisture so they sauté properly and don't steam in their own liquid.
What is the difference between shrimp and prawns for this recipe?
Shrimp are smaller (5-8 cm) and have a more concentrated and sweet flavor. Prawns are larger (10-15 cm), with a meatier and firmer texture. For classic gambas al ajillo, peeled shrimp are the traditional choice because they cook faster and absorb the oil's flavor better. Prawns work very well but need an extra minute of cooking and are usually butterflied to ensure even cooking.
Is a clay pot essential?
It's not essential, but highly recommended. A clay pot retains heat exceptionally well and keeps the shrimp sizzling for several minutes. If you don't have a clay pot, use a small cast-iron skillet, which also retains heat well. Avoid Teflon pans, which don't reach the necessary temperature for a good sauté and don't retain heat when serving.
How much olive oil do I really need?
More than you think. Gambas al ajillo are essentially shrimp confit in flavored oil; that oil is a fundamental part of the dish, not a secondary cooking medium. Aim for about 3-4 centimeters of depth in the pot, enough for the shrimp to be half-submerged. The leftover oil, perfumed with garlic and seafood, is liquid gold for dipping bread.
Why does my garlic always burn?
The most common mistake is to heat the oil too much before adding the garlic. Sliced garlic browns in seconds in very hot oil. The solution is to start with the oil at a medium temperature (140-150 °C) and keep an eye on it and stir continuously. If the garlic starts to darken, remove the pot from the heat immediately. Remember that the garlic will continue to cook with residual heat.
Can I prepare gambas al ajillo in advance?
It is not recommended. Gambas al ajillo is a dish to be eaten immediately; reheating them will overcook the shrimp and you will lose the crispy texture of the garlic. What you can do is prepare everything (peeled and dry shrimp, sliced garlic, measured ingredients) and cook it just before serving, as cooking only takes about 5 minutes.
What type of olive oil is best for gambas al ajillo?
Use an extra virgin olive oil with a mild or medium flavor, not an intensely pungent or bitter one. Arbequina or Hojiblanca varieties are ideal. An overly strong oil will compete with the flavor of the garlic and shrimp instead of complementing it. Do not use refined olive oil (the one labeled simply "olive oil"): it lacks the flavor and benefits of extra virgin.
Can this dish be made without chili?
Of course. Chili adds a spicy kick that enhances the flavors, but it's not essential. If you don't like spice, simply omit it. You can also add it whole without breaking it, which provides a very subtle heat. Another option is to use sweet paprika from La Vera instead, which will add color and a smoky aroma without the heat.
