Sauce. Start by making the sauce -- melt the butter (2 tablespoons) over medium heat in a medium saucepan. Add onion (1/2 cup) and saute until soft, about 3 minutes. Add the garlic (4 cloves) and cook until fragrant, about 1 minute. Add the white wine (1/2 cup), and give everything a good stir. Bring the wine to a simmer, and continue to cook until most of the liquid is gone. (Start the salmon while reducing). Add the veggie broth (1 cup), salt (1/4 teaspoon), pepper (1/2 teaspoon), dijon (2 tablespoons), and thyme (1 tablespoon). Bring sauce back to a simmer and continue to cook until it has reduced by half -- about 15 minutes. Add the cream and cook for an additional 5 minutes to continue thickening the sauce.
Prep. Preheat oven to 400 F and line a baking sheet with parchment paper. Pat salmon (4-6 ounce) dry on both sides and spread out evenly on your baking sheet.
Crust. Add all crust ingredients to a food processor and pulse using 1-second intervals until well combined -- about 10-15 times. Sprinkle the crust over the salmon and press to adhere.
Bake in preheated oven for 10-15 minutes -- you'll know the salmon is done once the center is cooked through and it flakes with a fork easily.
Serve salmon with sauce spooned over the top. Enjoy!
