Ingredients

Instructions

  1. Step 1: Preheat oven to 400°F. On a baking sheet lined with parchment, toss 1 lb trimmed asparagus with 2 tbsp olive oil, 1/2 tsp sea salt, and 1/4 tsp black pepper. Roast for 12 minutes.

  3. Step 3: Bake salmon in the oven for 12-14 minutes until opaque and flaky.
  4. Step 4: Meanwhile, in a small bowl, whisk together 3 tbsp freshly squeezed lemon juice, 2 tbsp Whole30 compliant mayonnaise, 2 minced garlic cloves, and 2 tbsp finely chopped fresh dill until smooth and creamy.
  5. Step 5: Plate salmon fillets with roasted asparagus and drizzle each portion with the lemon dill sauce while warm.
