What is Black Garlic?

Black garlic isn’t a special variety of garlic; it’s ordinary garlic that has been aged under controlled humidity and temperature until it becomes black and soft. Its flavor transforms into something sweet, earthy, and mellow. If you’ve never tried it before, it’s well worth seeking out—especially for recipes like this one, where its subtle sweetness and deep umami can really shine.

Ingredients

For 2 servings, you’ll need:

  • 2 cod fillets (Kabeljau) (about 150–200 g each)

  • Salt and freshly ground black pepper (to taste)

  • 1–2 tablespoons of neutral cooking oil (such as canola or vegetable oil)

  • 2 tablespoons unsalted butter (softened)

  • 2 cloves black garlic, finely chopped (or mashed to a paste)

  • ½ tablespoon lemon zest (from 1 fresh lemon)

  • 1 tablespoon fresh lemon juice

  • Optional garnish: Chopped parsley or chives

Step-by-Step Instructions

  1. Prepare the lemon-black garlic butter

    • In a small bowl, combine softened butter, black garlic, lemon zest, and a pinch of salt (if using unsalted butter).

    • Mash everything together until well mixed and set aside. If you prefer a thinner sauce, you can also add a tiny bit of olive oil to the butter mixture.

  2. Season the cod

    • Pat the cod fillets dry with paper towels.

    • Lightly season both sides with salt and freshly ground black pepper.

    • This is also a good time to let the fish come to room temperature for about 10–15 minutes—it ensures more even cooking.

  3. Sear the cod

    • In a nonstick or cast-iron skillet, heat the neutral cooking oil over medium-high heat.

    • When the oil is hot (it should shimmer), place the cod fillets in the pan.

    • Sear for 3–4 minutes on the first side, until the bottom edges start to turn golden brown.

    • Carefully flip and continue cooking for another 2–3 minutes, or until the fillets are opaque and flake easily with a fork.

  4. Add lemon juice

    • Just before the fish finishes cooking, add the lemon juice to the pan.

    • Tilt the pan slightly and spoon the lemony juices over the fillets to infuse extra flavor.

    • Turn off the heat once the cod is fully cooked (its internal temperature should reach 60–63°C or 140–145°F).

  5. Serve with black garlic butter

    • Transfer the cod fillets to a serving plate.

    • Immediately top each fillet with a spoonful of the lemon-black garlic butter.

    • The heat from the fish will melt the butter, creating a luxurious sauce right on the plate.

  6. Garnish and enjoy

    • For a splash of color, sprinkle some chopped fresh parsley or chives on top.

    • Serve warm, pairing it with a side of roasted vegetables, steamed greens, or creamy mashed potatoes.

Tips & Variations

  • Substitute Fish: Don’t have cod on hand? Try this recipe with other mild, flaky fish like haddock, pollock, or tilapia.

  • Extra Citrus: If you adore bright flavors, add a drizzle of fresh lemon juice right before serving.

  • Different Garlic: If black garlic isn’t available, use roasted garlic for a milder flavor. Regular fresh garlic can be used, but mince or grate it very finely and cook it gently in butter to avoid a sharp taste.

  • Spice it Up: Love heat? Add a pinch of chili flakes or cayenne to the lemon-black garlic butter.

  • Make it a Meal: Serve your cod on a bed of cooked quinoa, fluffy rice, or orzo pasta for a more substantial dish.
