How to Make Fennel Crusted Halibut with Asparagus
-
Prep the Asparagus: Cut off the top 2-3 inches of the asparagus and set aside. Trim off the tough ends, then slice the remaining stalks into very thin disks, about 1/4 inch thick. This ensures even cooking and tenderness.
-
Sauté Shallots and Asparagus: In a small saucepan, cook the diced shallot in butter or olive oil over medium heat for about 3 minutes, stirring until golden and fragrant. Add the asparagus disks and sauté for 1-2 minutes before adding the stock. Simmer gently for 4-5 minutes until fork-tender, creating a lovely rich sauce.
-
Blend the Sauce: Remove from heat and let the mixture cool slightly. Pour it into a blender along with salt, tarragon, and a squeeze of lemon juice. Blend until silky smooth, taste and adjust seasoning if necessary. Set aside this vibrant sauce that enhances the dish.
-
Season the Halibut: Pat the halibut filets dry with a paper towel, then sprinkle all sides generously with salt and pepper. Press fennel seeds onto the top of the filets, ensuring a flavorful crust.
-
Sear the Fish: Heat butter or olive oil in a large skillet over medium heat. Place the fish, fennel-side down, in the skillet and sear until golden brown—approximately 4 minutes. Flip the fish and add the reserved asparagus tips and sliced radishes. Season lightly with salt and pepper for balanced flavor.
-
Finish Cooking: Cook until the fish is done to your liking, then squeeze fresh lemon juice over the top for brightness. Gently warm the asparagus sauce in a separate pan, stirring frequently to keep it silky.
-
Plate and Serve: Generously divide the asparagus sauce onto two plates. Place the seared halibut filets on top, followed by the sautéed asparagus tips and radishes. Garnish with fresh tarragon leaves and serve alongside lemon wedges for an inviting touch.
Optional: Drizzle with extra olive oil before serving for added richness.

Tips for the Best Fennel Crusted Halibut
-
Fresh Ingredients: Use fresh tarragon and asparagus for maximum flavor. Dried herbs won’t deliver the same aromatic punch in the Fennel Crusted Halibut with Asparagus dish.
-
Pat Dry: Ensure the halibut is thoroughly patted dry before seasoning. Excess moisture can prevent the fish from searing properly and developing that golden crust.
-
Mind the Heat: Sear the fish at medium heat for a perfect crust. Too high heat may burn the fennel seeds before the fish cooks through.
-
Blender Care: Allow the asparagus mixture to cool slightly before blending to prevent splattering. A smooth sauce adds a touch of elegance to your plating.
-
Taste as You Go: Adjust seasoning to your preference. A touch more lemon or salt can elevate your Fennel Crusted Halibut with Asparagus to perfection.

Fridge: Keep leftovers in an airtight container for up to 3 days. Ensure the fish is fully cooled before sealing to maintain its texture.

Reheating: To enjoy the halibut again, thaw overnight in the fridge, then reheat gently in a skillet over medium-low heat, adding a splash of stock to keep it moist.
Asparagus Sauce: Store the sauce in the fridge for up to 4 days or freeze it in ice cube trays for easy portioning, lasting up to 3 months.

Fennel Crusted Halibut with Asparagus Recipe FAQs
What’s the best way to select fresh asparagus?
Absolutely! Look for asparagus spears that are firm and bright green. The tips should be closed and tightly packed, while the stalks should be free from dark spots or wrinkles. Freshness is key, so avoid any that appear wilted or rubbery.
How long can I store leftovers in the fridge?
You can keep leftover Fennel Crusted Halibut with Asparagus in an airtight container for up to 3 days. Just make sure the fish has cooled completely before sealing—this helps maintain its delicate texture.
Can I freeze the halibut or asparagus sauce?
Yes, you can! Wrap any extra halibut filets separately in plastic wrap and aluminum foil, and freeze them for up to 2 months. For the asparagus sauce, cool it first and then pour it into ice cube trays; once frozen, transfer the cubes to a freezer bag. This way, you can enjoy the sauce for up to 3 months—perfect for a quick meal later!
What should I do if the halibut isn’t searing properly?
Very! If your halibut isn’t searing well, it’s likely that it needs more heat, or it might be too wet. Ensure you’ve patted the filets dry thoroughly before seasoning them with salt and pepper. If you notice the skin is sticking to the pan, give it a little more time—it will release itself once it’s properly seared!
Is there a dietary concern for anyone allergic to fennel?
Absolutely! If you’re cooking for someone who has a fennel allergy, you can substitute the fennel seeds with sesame seeds or omit them entirely. The flavor profile will be different, but the dish will still shine with the existing ingredients, especially with the herbaceous tarragon and bright lemon.
What if I don’t have fresh tarragon?
No worries! While fresh tarragon adds unique flavor, you can substitute it with dried tarragon, using about one-third of the amount. Alternatively, dill or basil offer delicious substitutes, each bringing its own aromatic touch to your Fennel Crusted Halibut with Asparagus.
