Creamy dill cauliflower under a piece of salmon is the low carb swap for salmon and mashed potatoes. Same cozy feeling, way fewer carbs.
Preheat the oven to 400°F. Line a baking sheet with parchment paper for easy cleanup.
Arrange the salmon fillets skin-side down. Coat them lightly with 1 tbsp olive oil, a squeeze of lemon juice, salt, and black pepper. Let rest while preparing the cauliflower.
Steam cauliflower florets in a covered pot with ½ cup water over medium-high heat for 10-12 minutes, until fork-tender but not mushy. Drain well to remove excess moisture.
In a food processor, blend the hot cauliflower with butter, cream cheese, garlic powder, and half of the fresh dill until smooth and creamy. Taste and adjust seasoning with salt and pepper.
Roast the salmon in the oven for 10-12 minutes (or until it just flakes with a fork), monitoring closely to avoid overcooking. Thicker pieces may need an extra minute or two.
Spoon a generous mound of creamy dill cauliflower onto each plate. Top with a salmon fillet and garnish with remaining fresh dill and a drizzle of olive oil. Serve immediately.
