The combination of walnuts, breadcrumbs and butter makes for a delicious and crispy topping. Try it with other meats including pork, beef or chicken.
For the Crust:
- 1/4 cup panko breadcrumbs, whole-wheat
- 1/4 cup finely ground California walnuts (pulsed in a food processor)
- 4 tablespoons unsalted butter, at room temperature
- 1/2 teaspoon kosher salt
For the Arugula Pesto:
- 2 1/2 cups chopped baby arugula, tightly packed
- 1/4 cup grated Parmesan cheese
- 2 tablespoons chopped California walnuts
- 1 teaspoon minced garlic
- 1/2 teaspoon coarse kosher salt
- 1/3 cup extra-virgin olive oil
- 1 tablespoon walnut oil
For the Halibut:
- 3 tablespoons canola oil
- 6 each – 4 ounce halibut fillets
- 1/2 teaspoon kosher salt
- Prepare the crust. Toast panko breadcrumbs and walnuts in a dry skillet over medium heat for approximately 5 minutes; tossing often. They will become lightly toasted and fragrant. Transfer to a mixing bowl. Add butter and salt then mix until well incorporated.
- Lay a large piece of parchment paper out on the counter and top with crust mixture. Cover with another large piece of parchment paper. Press down to flatten slightly then with a rolling pin; roll out to 1/4-inch thick. Place in freezer on a flat surface to set.
- Meanwhile prepare the arugula pesto. Toasts walnuts in a dry skillet over medium heat for approximately 5 minutes; tossing often. They will become lightly toasted and fragrant
- In a food processor, combine arugula, Parmesan cheese, walnuts, garlic and kosher salt. Turn on and slowly add in extra-virgin olive oil and walnut oil until a paste forms, approximately 30 seconds. Transfer to a bowl, cover with plastic wrap and place in refrigerator.
- Now prepare the halibut. Preheat broiler on high.
- Remove crust from the freezer. Keep the parchment paper on and using kitchen shears cut 6 pieces into the same size as the halibut fillets.
- Working in 2 separate sauté pans, evenly heat canola oil over medium-high heat. Season halibut fillets with kosher salt. Once the oil is hot and smoking; add 3 halibut fillets per pan and sear for 5 minutes on one side then flip and sear for 3 minutes longer on the other side. Working in 2 pans will allow the fillets to cook evenly and not be over crowded in the pan.
- Remove one side of parchment paper from the crust and top each piece of halibut. Peel away the second side of parchment, repeating until all 6 are topped.
- Transfer the sauté pans under the broiler for approximately 2 minutes or until crust is golden brown and toasted.
- Spoon arugula pesto on the bottom of a large serving platter. Place crusted halibut on top and serve family style.
