Instructions
-
Preheat the oven to 425°F (220°C). Line a baking sheet with parchment paper or foil.

In a small bowl, mix together rosemary, thyme, garlic powder, lemon zest, salt, and black pepper to create the herb crust.

Pat the salmon fillets dry with paper towels and brush both sides with 1 tablespoon of olive oil.

Press the prepared herb mixture firmly onto the top sides of the salmon fillets, forming an even crust.

Arrange salmon fillets skin-side down on the prepared baking sheet.

Toss cauliflower florets with the remaining 1 tablespoon olive oil, salt, and pepper; spread evenly on a separate baking sheet.

Roast the cauliflower for 20-25 minutes, turning once halfway, until golden and tender.
-
Place the salmon in the oven and bake for 12-15 minutes until cooked through and easily flaked with a fork.
-
While baking, melt butter in a small skillet over medium heat. Add minced garlic and sauté for 1 minute until fragrant.

Transfer roasted cauliflower to a food processor or blender. Add garlic butter and heavy cream, then blend until smooth and creamy. Season with salt and pepper to taste.

Serve each salmon fillet on a bed of roasted cauliflower mash, garnished with chopped parsley and lemon wedges on the side.
