I know what you’re thinking – lobster isn’t kosher. You’re absolutely right, but that doesn’t mean we can’t enjoy something that captures those same luxurious flavors and elegant presentation. This recipe uses firm white fish fillets shaped and scored to mimic lobster tail, then baked with a rich garlic herb butter that’ll have your guests doing double takes.

I developed this dish for a friend’s anniversary dinner when she wanted something that felt special but followed kashrut. The secret is using thick halibut or cod fillets and scoring them in a crosshatch pattern before baking. This creates that distinctive lobster-like texture while the garlic butter infuses every crevice. The presentation is surprisingly convincing, especially when you arrange the fillets on individual plates with lemon wedges.

Creating the Perfect Fish Texture

What makes this version work so well is the technique of butterflying the fish slightly and creating those shallow cuts. Don’t go too deep or the fish will fall apart during cooking. I use about a quarter-inch depth, which is perfect for holding the flavored butter. The herb mixture I use includes fresh parsley, dill, and a touch of tarragon, which gives it that sophisticated taste you’d expect from an upscale restaurant.

When to Serve This Elegant Dish

This pairs beautifully with roasted asparagus or a simple green salad, and it’s elegant enough for Shabbat dinner or special occasions. The whole thing comes together in about 20 minutes, making it perfect when you want to impress without spending hours in the kitchen.

Ingredients Method Notes

Ingredients
  

  • 4 thick halibut or cod fillets 6-8 oz each, about 1.5 inches thick
  • 6 tablespoons butter room temperature
  • 4 cloves garlic minced fine
  • 2 tablespoons fresh parsley chopped
  • 1 tablespoon fresh dill chopped
  • 1 teaspoon fresh tarragon chopped, or 1/3 tsp dried
  • 1 tablespoon lemon juice freshly squeezed
  • 1/2 teaspoon kosher salt
  • 1/4 teaspoon black pepper freshly ground
  • 1 lemon cut into wedges for serving
  • 1 tablespoon olive oil for brushing pan

Method
 

  1. Preheat oven to 425°F. Brush a baking dish with olive oil.
  2. Pat fish fillets completely dry with paper towels. Using a sharp knife, make shallow crosshatch cuts about 1/4 inch deep across the top of each fillet, spacing cuts about 1/2 inch apart.
  3. In a small bowl, combine softened butter, minced garlic, parsley, dill, tarragon, lemon juice, salt, and pepper. Mix until well combined.
  4. Place fish fillets in the prepared baking dish. Spread the herb butter mixture evenly over the top of each fillet, pressing gently into the cuts.
  5. Bake for 10-12 minutes, or until fish flakes easily with a fork and reaches an internal temperature of 145°F. The butter should be golden and bubbling.
  6. Let rest for 2 minutes before serving. Garnish with lemon wedges and serve immediately.

Notes

Choose the thickest fish fillets you can find for the best presentation. If your fillets are thinner, reduce cooking time to 8-10 minutes. The herb butter can be made up to a day ahead and kept refrigerated. Pairs beautifully with roasted vegetables or a light salad.
