Cod al ajillo: the fastest and tastiest recipe
Cod al ajillo (garlic cod) is probably the fastest cod recipe there is. In just 15 minutes, with ingredients everyone has at home (garlic, olive oil, chili pepper, and cod), you can create a spectacular dish. It’s the classic "al ajillo" technique, applied to shrimp, mushrooms, and button mushrooms, adapted to desalted cod with an equally delicious result.
The secret of cod al ajillo lies in the infused oil: an extra virgin olive oil that has absorbed the aromas of sliced garlic and chili, and which is poured hot over the cod. The sizzling of the oil upon contact with the fish is a spectacle in itself, and the aroma that fills the kitchen announces that something exceptional is coming. At Mercat del Ninot, we constantly prepare it as a quick demonstration for our customers.
Ingredients for 4 people
- 4 desalted cod loins, 180-200g each, with skin
- 8-10 cloves of garlic, thinly sliced
- 2-3 dried chili peppers (or cayenne peppers)
- 200 ml extra virgin olive oil
- Fresh parsley, chopped
- 1 tablespoon white wine vinegar or sweet paprika (optional)
The cut: for al ajillo, both loins and tails work well. The important thing is that the pieces have a uniform thickness (2-3 cm) so that they cook evenly. The skin is essential: it protects the flesh from direct heat and adds gelatin to the oil.
Step-by-step preparation (15 minutes)
1. Dry and temper the cod (2 minutes)
Take the cod out of the refrigerator 10 minutes beforehand. Dry it thoroughly with paper towels. This step is especially important for al ajillo because hot oil splashes violently if the cod is wet.
2. Sear the cod (5-6 minutes)
In a wide frying pan, heat 3-4 tablespoons of olive oil over medium-high heat. Place the loins skin-side down. Cook for 3-4 minutes without moving until the skin is crispy and golden. Flip and cook for 2 more minutes on the flesh side. Don't aim for full cooking: the cod will finish cooking with the hot oil. Set the loins aside on a plate or in an earthenware dish.
3. Prepare the garlic oil (3-4 minutes)
In the same pan (or a clean one), pour the rest of the olive oil. Heat over medium-low heat. Add the sliced garlic and broken chili peppers. Cook over low heat for 2-3 minutes, stirring occasionally, until the garlic is lightly golden and crispy. Watch carefully: garlic goes from golden to burnt in seconds. Burnt garlic will bitter the entire dish.
4. Pour the oil over the cod
Remove the pan from the heat. If using vinegar, add it now to the hot oil (be careful, it splatters). Pour the oil with the garlic and chili peppers directly over the reserved cod loins. You'll hear the characteristic sizzling. Sprinkle generously with fresh chopped parsley.
5. Serve immediately
Cod al ajillo is eaten hot, freshly made. Serve directly in the earthenware dish with bread for dipping in the fragrant oil.

Tips for a perfect ajillo
- Garlic sliced thinly, not minced: sliced garlic browns evenly and becomes crispy. Minced garlic burns on the outside and remains raw on the inside.
- Low heat for the garlic: garlic is cooked over medium-low heat. If the oil is smoking, it's too hot. Golden garlic is sweet and crispy; burnt garlic is bitter and unpleasant.
- Seedless chili: if you want mild spice, remove the seeds from the chili before adding it. The seeds contain most of the capsaicin.
- Parsley at the end: fresh parsley is always added off the heat. If you add it to hot oil, it fries instantly and loses its freshness and green color.
- Earthenware dish: if you have one, use it for serving. Ceramic retains heat and keeps the cod warm throughout the meal. Plus, the presentation is much more attractive.
- A splash of vinegar (optional): a tablespoon of white wine vinegar added to the hot oil just before pouring provides an acidic touch that balances the oil's richness. It's a very effective Andalusian trick.
Variations of cod al ajillo
Cod al ajillo with paprika
Add a teaspoon of "pimentón de la Vera" (sweet or spicy paprika) to the hot oil just a second before removing it from the heat. Paprika provides an intense red color, a smoky flavor, and integrates perfectly with the garlic and chili. Don't leave it in the hot oil for more than 2-3 seconds or it will burn.
Cod al ajillo with cherry tomatoes
Add 8-10 cherry tomatoes, cut in half, to the pan with the sliced garlic. Cook for 3-4 minutes until lightly roasted and they begin to release their juices. Pour everything together over the cod. The tomatoes add freshness, sweetness, and color.
Cod al ajillo with shrimp
Surf and turf: sear the cod, set aside, and in the same oil, prepare some garlic shrimp before pouring everything together. A quick and spectacular party dish.
Baked cod al ajillo
If you prefer less oil, place the loins on a baking sheet, scatter the sliced garlic and chili peppers over them, drizzle with oil, and bake at 200 °C for 12-15 minutes. Less oil but the same great flavor.
Ideal side dishes
- Rustic bread: essential for dipping in the garlic oil. A good country bread, ciabatta, or Galician baguette.
- French fries or baked potato slices: potatoes absorb the garlic oil and become the best side dish in the world.
- Padrón or piquillo peppers: fried or roasted, alongside the cod.
- Green salad: a fresh counterpoint to balance the intensity of the garlic and oil.
- White rice: for a heartier version, serve over rice to absorb the oil.
Origin of cod al ajillo
The "al ajillo" technique is one of the oldest and most universal in Spanish cuisine. Its origin is in Andalusia and Castile, where garlic and olive oil were (and still are) the most accessible ingredients. The most internationally known version is gambas al ajillo (garlic shrimp), but the technique has historically been applied to any protein: mushrooms, tripe, chicken, rabbit, and, of course, cod.
Cod al ajillo has a special tradition during Lent, a period when meat was forbidden and cod was the protein of choice. The al ajillo technique allowed dry, salted cod to be transformed into a fragrant, juicy, and festive dish with ingredients that every home had: garlic, oil, and chili. In many inland towns in Spain, especially in Castilla-La Mancha, Extremadura, and Andalusia, cod al ajillo remains an essential Holy Week dish.
Pairing: what wine to serve
Cod al ajillo pairs well with wines that can compete with the intensity of garlic and oil:
- Albariño (Rías Baixas): the acidity of Albariño cuts through the oil's richness, and its fruity profile balances the garlic. The classic Galician combination.
- Godello (Valdeorras): more body than Albariño, with mineral notes that accompany al ajillo well.
- Verdejo (Rueda): herbal and fresh, it harmonizes with the parsley and chili.
- Fino or Manzanilla (Jerez): the perfect Andalusian option. The salinity of Fino mimics that of the cod, and its bitterness complements the garlic. Serve very cold.
- Craft beer: a cold blonde or pale ale works just as well as any wine, especially in summer.
Common mistakes when making cod al ajillo
Avoid these mistakes that ruin the dish:
- Burning the garlic: the number one mistake. Burnt garlic bitters all the oil and the entire dish. Always use medium-low heat. Remove from heat as soon as the garlic is lightly golden.
- Wet cod: if you don't dry the cod, the water causes dangerous oil splatters and the cod also steams in its own water instead of searing. Dry it thoroughly with paper towels.
- Insufficient oil: al ajillo needs generous oil. Don't skimp: the leftover oil is the sauce for the dish, to be soaked up with bread.
- Overcooked cod: the cod continues to cook with the residual heat from the oil. Remove it from the pan when it's still slightly underdone and let the hot oil finish cooking it.
Nutritional information
Cod al ajillo has more calories than other preparations due to the amount of oil, but it is a virgin olive oil with healthy fats:
- Calories: 320-380 kcal per serving (the oil actually consumed is a fraction of the total)
- Protein: 22-26 g from the cod
- Fats: 24-30 g (primarily from olive oil: oleic acid, monounsaturated fats)
