BBQ Cod: 5 Summer Recipes

Why cod works on the barbecue

Summer barbecues usually revolve around red meats, burgers, and ribs. But barbecued cod breaks the mold with spectacular results. There are three technical reasons that explain this:

Firmness of the flesh. Salted cod, once desalted, maintains a firm and compact texture that doesn't fall apart when it comes into contact with the grill. Unlike more delicate fish like hake or sole, cod loins have the necessary consistency to withstand the direct heat of the coals without breaking.

Flavor absorption capacity. The protein structure of cod, modified by the salting and subsequent desalting process, creates a porous surface ideal for absorbing marinades, smoke, and spices. This means that the smoky flavor of wood or charcoal penetrates cod more deeply than other fresh fish.

Thermal contrast. In summer, we look for dishes that aren't too heavy. Grilled cod offers the barbecue experience—the aroma of the flames, the crispy crust—but with much lighter digestion than meats. It's quality protein, low in fat, with all the flavor of fire.

In countries like Portugal, bacalhau na brasa is an absolute summer night classic. In Spain, the tradition exists in areas like the Basque Country and Navarre, where grilled cod has appeared in cider houses and grill restaurants for generations. What we're doing here is bringing that tradition to your patio.

How to choose the perfect cut for grilling

Not all parts of the cod work equally well on the barbecue. The cut you choose determines the final result:

• Thick loins (center of the loin): the best option. They have uniform thickness, cook evenly, and withstand direct heat well. Look for pieces at least 3 cm thick. In our cod section, you'll find selected loins that are perfect for barbecuing.
• Kokotxas (cod cheeks): a gourmet option. They grill quickly (2-3 minutes per side) and their gelatinous texture creates a striking contrast with the grilled crust.
• Flakes and shredded cod: not ideal for direct grilling, but if you wrap them in aluminum foil with vegetables, they work well as a side dish.
• Tails: thinner, they dry out easily. If you use them, cook indirectly or en papillote.

Golden rule: the thicker the piece, the more margin for error you have. A 4 cm loin allows you to achieve a crispy exterior and a juicy interior without complications.

Desalting cod: an essential pre-step

If you use salted cod, you need to desalt it properly before barbecuing. The process is simple but requires planning:

1. Cut the cod into the portions you plan to grill. Smaller pieces desalt faster.
2. Submerge it in cold water in the refrigerator. Cold is key to maintaining food safety in summer.
3. Change the water every 8 hours, for a total of 3 changes (24 hours for thick loins, 16-18 for medium pieces).
4. Taste a small piece before marinating. It should taste slightly salty, not bland: the residual salt enhances the flavor when grilled.

A specific trick for barbecue: if you want a more pronounced saltiness that works with sauces or aiolis, desalt for a couple of hours less than usual. The heat from the coals intensifies flavors, and a little extra saltiness works well.

For those who prefer to skip this step, desalted cod is the quick route: take it out of the package, pat dry, marinate, and grill.

Recipe 1: Grilled cod loins with smoked aioli

This is the signature recipe: cod loins cooked directly over the coals, with a crispy outer crust and an interior that flakes apart juicily. The smoked aioli is what elevates it to another level.

Ingredients (4 servings)

• 4 desalted cod loins (200-250 g each, minimum 3 cm thick)
• Extra virgin olive oil
• 4 cloves of garlic
• Flaky sea salt (Maldon or similar)
• Freshly ground black pepper
• 1 lemon

For the smoked aioli

• 4 cloves of garlic roasted on the grill
• 1 egg yolk at room temperature
• 200 ml mild olive oil
• 1 teaspoon smoked paprika from La Vera
• Juice of half a lemon
• Salt

Preparation

1. Prepare the coals: you need white coals, no flame. Medium-high temperature (you should be able to hold your hand 15 cm above for about 3-4 seconds). If using a gas barbecue, 200-220 degrees.
2. Pat the loins dry with kitchen paper. Surface moisture is the enemy of a crispy crust. This step is essential.
3. Brush generously with oil on both sides. This prevents sticking and helps with caramelization.
4. Place on the grill skin-side down. If the loins have skin, always start on that side. The skin protects the flesh and becomes crispy.
5. Cook for 4-5 minutes on the skin side without moving. Do not touch, turn, or poke. Let the protein sear.
6. Flip once carefully, using a wide spatula. Cook for another 3-4 minutes on the other side.
7. Remove when the center is still slightly translucent. Residual heat will finish the cooking. If you wait until it's completely opaque, it will be dry.

For the smoked aioli: roast the garlic cloves directly on the coals (5 minutes wrapped in aluminum foil). Peel them, mash them in a mortar with salt, add the yolk, and emulsify by adding oil in a thin stream while whisking. Finally, incorporate the smoked paprika and lemon.

Serve the loins with the aioli on the side, flaky salt on top, and a drizzle of extra virgin olive oil.

Recipe 2: Cod skewers with pepper and red onion

Skewers are the perfect format for barbecues with friends: easy to serve, visually appealing, and allow for combining flavors. Cod cut into large cubes holds up surprisingly well on a skewer.

Ingredients (4 servings, 8 skewers)

• 600 g desalted cod cut into 3x3 cm cubes
• 2 red bell peppers cut into squares
• 2 red onions cut into quarters and separated into layers
• 1 zucchini cut into thick slices
• Cherry tomatoes

Mediterranean marinade

• 100 ml olive oil
• Juice of 1 lemon
• 2 minced garlic cloves
• 1 tablespoon dried oregano
• 1 teaspoon sweet paprika
• Black pepper

Preparation

1. Mix all marinade ingredients in a large bowl.
2. Submerge the cod cubes in the marinade and let them rest for 30 minutes in the refrigerator. No more than 1 hour: the acid from the lemon would start to "cook" the fish.
3. Skewer alternately: cod, pepper, onion, cod, zucchini, tomato. Leave a little space between pieces for heat to circulate.
4. Cook on the barbecue over medium heat for 8-10 minutes, turning a quarter turn every 2-3 minutes.
5. Brush with the leftover marinade each time you turn.

Tip: if using wooden skewers, soak them in water for at least 30 minutes beforehand so they don't burn. Metal skewers conduct heat to the interior and accelerate cooking.

Recipe 3: Barbecued cod en papillote with summer vegetables

Papillote on the barbecue combines the best of both worlds: the cod steams inside its wrapper while absorbing the subtle smoky aroma that penetrates the aluminum. It's the easiest option for those who fear the fish sticking or breaking apart.

Ingredients (4 servings)

• 4 desalted cod loins
• 2 ripe tomatoes cut into thin slices
• 1 zucchini julienned
• 1 green bell pepper cut into strips
• 12 black olives from Aragon
• Capers
• Extra virgin olive oil
• White wine (a splash per packet)
• Fresh herbs: thyme, rosemary, basil

Preparation

1. Cut 4 double aluminum foil rectangles, large enough to loosely wrap each loin.
2. Distribute a bed of vegetables in the center of each rectangle.
3. Place the loin on top, season with pepper and herbs, add olives and capers, a splash of white wine, and generous olive oil.
4. Seal the packets by folding the edges several times. It should be airtight but with internal space for steam to circulate.
5. Place on the barbecue in an indirect heat zone (not directly over the coals) for 15-18 minutes.
6. Open at the table so the aroma impacts the diners. Be careful with the steam.

This method is perfect for quality desalted cod, as it preserves all the juiciness and enhances the flavors of seasonal vegetables.

Recipe 4: Citrus-marinated cod on the barbecue griddle

If your barbecue has a griddle or you can place an iron griddle over the coals, this recipe uses a citrus marinade to create an impressive caramelized exterior. It's the summer version of confit cod, but much lighter.

Ingredients (4 servings)

• 4 desalted cod loins
• Juice and zest of 1 orange
• Juice of 1 lime
• 2 tablespoons honey
• 3 tablespoons olive oil
• 1 fresh chili pepper, finely chopped (optional)
• Fresh cilantro
• 1 teaspoon grated fresh ginger

Preparation

1. Mix orange juice, lime, honey, oil, chili, and ginger. Reserve one-third of the marinade for serving.
2. Marinate the cod for 20-30 minutes in the refrigerator. The honey and citrus will create a caramelized crust on the griddle.
3. Heat the griddle until very hot. A drop of water should evaporate instantly.
4. Cook for 3-4 minutes per side, brushing with marinade when flipping.
5. Serve with the reserved marinade drizzled on top, chopped fresh cilantro, and orange zest.

The sweet-sour-spicy-smoky contrast makes this dish a complete experience. Serve with a green salad and crystal bread toasted on the grill.

Recipe 5: Grilled cod with express pil-pil sauce

The classic Basque pil-pil, adapted for the barbecue. The cod fat that drips onto the grill is collected in an auxiliary pan to create the emulsion. It's an impressive dish with deep roots in Basque gastronomy.

Ingredients (4 servings)

• 4 desalted cod loins with skin (essential for pil-pil)
• 150 ml extra virgin olive oil
• 6 sliced garlic cloves
• 1 dried chili pepper
• Fresh parsley

Preparation

1. In a pan that you can place on the barbecue (cast iron is ideal), heat the oil over low heat with the sliced garlic and chili. Remove when the garlic is golden.
2. Grill the loins for 4 minutes on the skin side, 3 on the other. Remove and set aside on a plate.
3. Collect the cod juices that have remained on the plate and add them to the oil in the pan.
4. Off the heat, move the pan in constant circles. The gelatin from the cod will emulsify with the oil, creating the pil-pil sauce, thick and pearly.
5. If it doesn't emulsify, add a tablespoon of cold water and keep moving. Patience is key.
6. Pour the sauce over the loins, garnish with the golden garlic and chopped parsley.

This dish works especially well with premium cod loins, where natural gelatin is abundant and facilitates emulsification.

Times and temperatures: the definitive table

The biggest mistake in barbecuing fish is overcooking it. Here's the exact reference according to cut and method:

Meat thermometer: if you have one, the target internal temperature is 60-63 degrees in the center. Above 65 degrees, the cod starts to dry out quickly.

5 Mistakes That Ruin Barbecued Cod

1. Not drying the cod before grilling. Surface moisture prevents the Maillard reaction (the crust from forming). Pat both sides dry with paper towels just before placing it on the grill.
2. Cold grill or with active flames. The coals should be white, with no active flames. A grill that isn't hot enough will cause the fish to stick.
Moving or flipping too soon. The cod initially sticks and only releases once the crust has formed. If it resists when you try to flip it, it's not ready. Wait another minute.
3. Overcooking. Cod goes from juicy to cardboard in a matter of 2 minutes. Always remove it a little sooner than you think necessary.
4. Insufficient desalting. Cod that is still very salty will become even saltier with the heat of the grill, which concentrates flavors. If anything, it's better to slightly over-desalt than to under-desalt.

Summer Sides for Grilled Cod

Barbecued cod calls for fresh sides that contrast with the heat of the grill:

• Tomato and red onion salad with sherry vinaigrette and fresh basil
• Roasted Padrón peppers directly on the barbecue (2-3 minutes)
• Baked potatoes wrapped in foil among the coals (45 min before the cod)
• Gazpacho in small glasses as a cold appetizer while the cod is grilling
• Crystal bread toasted on the grill with rubbed tomato
• Escalivada prepared on the barbecue: whole roasted peppers, eggplants, and onions

For a complete seafood barbecue, combine the cod with Cantabrian anchovies as an appetizer on toast while the grill is heating up. You can also include smoked salmon on a charcuterie board as a cold starter.

Special Summer Marinades

Marinating is optional but transforms the result. These are the combinations that work best with cod on the barbecue:

Provençal marinade: olive oil + herbs de Provence + garlic + lemon. Classic, reliable, elegant. 30 minutes.

Asian marinade: soy sauce + mirin + ginger + sesame. Creates a spectacular caramelized crust due to the sugars in the mirin. Maximum 20 minutes (soy sauce adds salt).

Spicy marinade: oil + spicy paprika + garlic + cumin + lemon. For those who want an extra kick of heat on summer nights. 30 minutes.

Sweet-smoky marinade: honey + Dijon mustard + smoked paprika + sherry vinegar. The honey caramelizes on the grill, creating a dark, almost glazed crust. 20 minutes.

Important: never marinate for more than 1 hour. Acids (lemon, vinegar) denature the fish proteins, and the texture becomes soft, similar to ceviche, which prevents a good crust from forming on the barbecue.

Food Safety for Summer Barbecues

Summer heat is the enemy of seafood. Follow these rules to enjoy safely:

• Cold chain: keep the cod in a cooler with ice until it's time to grill. Never leave it at room temperature for more than 30 minutes in summer.
• Safe desalting: always in the refrigerator, never at room temperature. In summer, bacteria multiply rapidly.
• Separate cutting boards: use one board for raw cod and another for cooked cod. The same rule applies to utensils.
• Leftovers: refrigerate within 1 hour. Grilled cod lasts 2-3 days in the refrigerator and is excellent cold in a salad the next day.

Pairing: What to Drink with Grilled Cod

The smoky flavor of the barbecue calls for wines with a certain structure, not the lightest whites:

• Albariño aged on lees: the wine's texture complements the cod's richness.
• Godello from Valdeorras: minerality and enough body for the smoky flavor.
• Barrel-fermented Verdejo: the toasted notes of oak harmonize with the grill.
• Navarra Rosé: if the recipes include peppers or tomatoes, rosé is perfect.
• Craft pale ale beer: the bitter hops cleanse the palate between bites of smoked cod.
