Instructions

  1. Step 1: Preheat oven to 400°F (200°C). Toss 1 cup diced sweet potato with 1 tsp avocado oil and 1/2 tsp sea salt, spreading in a single layer on a parchment-lined baking sheet.
  2. Step 2: Roast for 20 minutes until edges are golden and tender when pierced with a fork, flipping halfway through for even browning.
  3. Step 3: While potatoes roast, mix 1 tbsp white miso paste with 1 tsp lemon zest and 1 tsp fresh thyme to create a glaze.
  4. Step 4: Pat salmon fillets dry, brush with miso glaze, and place skin-side down on a separate baking sheet. Bake for 12 minutes until the salmon is opaque and flakes easily with a fork.
  5. Step 5: Plate roasted sweet potato with salmon, drizzling any remaining glaze from the pan over the top for maximum flavor and nutrient absorption.
