Ingredients

For the Fish and Asparagus:

  • 4 (6-oz) white fish fillets (such as cod, halibut, tilapia, or sea bass), patted very dry

  • 1 bunch asparagus, woody ends trimmed

  • 2 tbsp avocado oil or light olive oil (for high-heat cooking)

  • 1 tbsp unsalted butter

  • Salt and freshly ground black pepper, to taste

  • Pinch of red pepper flakes (optional, for heat)

For the Garlic Butter Sauce:

  • 4 tbsp unsalted butter, cut into tablespoons

  • 4 cloves garlic, thinly sliced

  • 2 tbsp fresh lemon juice (about 1 lemon)

  • 1 tsp lemon zest

  • 2 tbsp fresh parsley, chopped

  • 1 lemon, cut into wedges, for serving

Instructions

1. Prepare the Fish (5 minutes):
Start by ensuring your fish fillets are as dry as possible. Use paper towels to pat them down thoroughly. This is the secret to a good sear. Season both sides generously with salt and pepper.

2. Sear the Fish (6-8 minutes):
Heat the avocado oil in a large, heavy-bottomed skillet (like cast-iron or stainless steel) over medium-high heat. Once the oil is shimmering and hot, carefully place the fish fillets in the pan, presentation side down. Do not overcrowd the pan; cook in batches if necessary.

Cook for 3-4 minutes without moving them, until the underside is golden brown and the fish easily releases from the pan. Carefully flip and cook for another 2-3 minutes, or until the fish is opaque and flakes easily with a fork. The exact time will depend on the thickness of your fillets. Transfer the cooked fish to a plate and tent loosely with foil to keep warm.

3. Cook the Asparagus (3-4 minutes):
In the same skillet, reduce the heat to medium. There should still be some oil left. Add 1 tablespoon of butter to the pan. Once melted, add the trimmed asparagus in a single layer. Season with a pinch of salt, pepper, and red pepper flakes (if using).

Cook, tossing occasionally, for 3-4 minutes, until the asparagus is bright green and tender-crisp. Use tongs to transfer the asparagus to the plate with the fish.

4. Make the Garlic Butter Sauce (3 minutes):
Reduce the heat to low. Add the remaining 4 tablespoons of butter to the skillet. As it melts, it will begin to foam and then turn a light, nutty brown color. Swirl the pan frequently. Immediately add the sliced garlic and cook for about 30-60 seconds until fragrant. Be careful not to burn the garlic.

5. Finish and Serve (2 minutes):
Remove the pan from the heat. Stir in the fresh lemon juice, lemon zest, and most of the chopped parsley (reserve a little for garnish). The sauce will sizzle slightly. Taste the sauce and adjust seasoning with a little more salt or pepper if needed.

Return the fish and asparagus to the skillet, or place them on a serving platter and spoon the hot garlic butter sauce generously over the top. Garnish with the remaining fresh parsley and serve immediately with extra lemon wedges on the side.

Recipe Notes

  • Fish Options: This recipe works beautifully with any firm, white fish. Cod and halibut are great choices for a meatier texture, while tilapia or flounder will cook even faster. Just ensure your fillets are of similar thickness for even cooking.

  • Don’t Move the Fish: Resist the urge to poke or move the fish while it’s searing. Letting it be is what creates that beautiful, crispy crust and prevents it from sticking.

  • Sauce Consistency: If your sauce seems too thin, you can whisk in another small pat of cold butter off the heat to emulsify it and give it a glossier, thicker consistency.

  • Make it a Feast: Serve this with a side of cauliflower rice or zucchini noodles to soak up every last drop of the incredible garlic butter sauce.
