– 3 tablespoons freshly squeezed lemon juice
– 1 teaspoon finely grated lemon zest
– 1 tablespoon fresh parsley, finely chopped
– 1 teaspoon Dijon mustard, optional
– 1/4 teaspoon black pepper

Instructions
1. Prepare the halibut
Pat the halibut fillets completely dry with paper towels. Removing excess moisture helps the fish develop a beautiful golden crust.
Check for any remaining bones and remove them carefully. Season both sides with salt, black pepper, garlic powder, and paprika if using.
For a slightly crispier exterior, lightly dust the fillets with flour and shake off any excess.
2. Heat the pan
Place a large nonstick or stainless-steel skillet over medium-high heat. Add the olive oil and 2 tablespoons of butter.
Allow the butter to melt and the pan to become hot, but do not let the butter burn.
3. Sear the halibut
Carefully place the fillets in the skillet, leaving space between them. Cook for approximately 4–5 minutes on the first side, depending on thickness, until golden brown.
Flip gently using a fish spatula. Cook for another 3–5 minutes, until the fish is opaque and flakes easily with a fork.
The center should reach 145°F (63°C) for food safety. Thicker fillets may require additional cooking time.
Transfer the cooked fish to a warm plate and loosely cover it while you prepare the sauce.
4. Sauté the garlic
Reduce the heat to medium-low. If the pan contains excessive browned bits or burnt butter, carefully wipe out the burnt portions while retaining the flavorful fond.
Add the remaining 3 tablespoons of butter. Once melted, add the minced garlic and cook for about 30–45 seconds, stirring constantly.
The garlic should become fragrant without turning dark brown.
5. Add the capers
Stir in the drained capers and cook for approximately 30 seconds.
Gently press a few capers with the back of a spoon to release more of their tangy flavor into the butter.
6. Build the lemon sauce
Pour in the chicken broth or seafood stock. Add the freshly squeezed lemon juice, lemon zest, and Dijon mustard if using.
Stir well, scraping up any flavorful browned bits from the bottom of the skillet.
Allow the sauce to simmer gently for 2–3 minutes, until slightly reduced. Avoid boiling it vigorously, as the butter can separate.
7. Adjust the flavor
Stir in the black pepper and chopped parsley.
Taste the sauce before adding salt because capers and stock can already be salty. If the sauce tastes too sharp, add a small amount of butter. If it is too strong or concentrated, add 1–2 tablespoons of broth.
8. Return the halibut to the skillet
Carefully place the cooked fillets back into the pan. Spoon the lemon caper butter sauce over each piece.
Let the fish warm in the sauce for 1–2 minutes over low heat. Avoid prolonged cooking, which can dry out the delicate fish.
9. Garnish and serve
Transfer the halibut to serving plates. Spoon plenty of lemon caper sauce over the top, making sure each portion gets some capers and garlic.
Garnish with fresh parsley and lemon slices. Serve immediately with roasted potatoes, rice, asparagus, or your favorite vegetables.
Tips for Perfect Lemon Caper Halibut
– Dry the fish thoroughly before seasoning to achieve a better sear.
– Use fresh lemon juice for a brighter, fresher flavor.
– Do not overcrowd the skillet; cook in batches if necessary.
– Handle halibut gently because its delicate flakes can break apart.
– Keep the sauce at a gentle simmer to maintain its buttery texture.
– If using frozen halibut, thaw it completely in the refrigerator and pat it dry before cooking.
– For extra richness, swirl a small knob of cold butter into the finished sauce just before serving.
Easy Variations
– Creamy lemon caper halibut: Add 2–3 tablespoons of heavy cream to the sauce.
– Mediterranean-style halibut: Add halved cherry tomatoes and a few sliced olives.
– Garlic herb halibut: Add fresh dill or thyme along with the parsley.
– Spicy lemon caper halibut: Add a pinch of red pepper flakes with the garlic.
– Dairy-free version: Replace butter with a suitable dairy-free butter alternative or additional olive oil.
– Gluten-free version: Omit the optional flour and check that your broth and Dijon mustard are certified gluten-free if needed.
Storage and Reheating
– Refrigerator: Store leftovers in an airtight container for up to 3 days.
– Freezer: For best quality, freeze cooked halibut and sauce in a freezer-safe container for up to 2 months.
– Reheating: Warm gently in a covered skillet over low heat with a splash of broth. Avoid high heat, which can make the fish dry.
– Food safety: Refrigerate leftovers within 2 hours of cooking and reheat to 165°F (74°C).
