2tablespoonsfreshly grated Parmesan, plus more if desired
1teaspoonWorcestershire sauce
½teaspoongarlic powder
¼teaspoonred pepper flakes (optional)
Lemon Yogurt Sauce:
½cupplain Greek yogurt
1tablespoonDijon mustard (regular or whole-grain)
1tablespooncapers
½lemon, juiced
Instructions
Move an oven rack to about 4" away from the broiler. Preheat broiler to high.Brush an oven-safe pan or casserole dish with oil. Sprinkle halibut with salt and place it in the oiled pan. Set aside.
In a small bowl, mix together the mayo, Parmesan, Worcestershire, garlic powder and red pepper flakes (if using). Generously top the halibut fillets with the mayo and cheese mixture, smoothing the mixture out with the back of a spoon.If desired, top the fish with a little more Parmesan.
Slide the pan into the oven.Cook halibut for 8 minutes per 1" thickness, or until the fish is opaque and beginning to flake apart, and the top is golden brown.Do not flip the fish halfway through cooking.
While the halibut cooks, add the yogurt, mustard, capers, and lemon juice to a small bowl and whisk to blend. The sauce flavor and thickness will vary depending on the yogurt and mustard used. Taste the sauce. Add more mustard if desired, or more yogurt if the sauce seems too spicy. If the sauce is too thick, add a little juice from the caper jar.When the halibut is done cooking, remove it from the oven and move the fish to plates. Serve immediately along with sauce.
