Instructions

  1. Step 1: Place 2 medium peeled and cubed sweet potatoes into a large pot and cover with cold water. Bring to a boil over high heat and cook for 15 minutes until tender when pierced with a fork. Drain and return to the pot.
  2. Step 2: Add 2 tablespoons ghee and 1/2 teaspoon sea salt to the sweet potatoes and mash with a potato masher until smooth and creamy. Cover to keep warm.
  3. Step 3: Heat 2 tablespoons olive oil in a large nonstick skillet over medium-high heat. Season 4 salmon fillets with 1/2 teaspoon sea salt and 1/4 teaspoon black pepper. Place the fillets skin-side down and cook for 4 minutes until the edges are crispy.
  4. Step 4: Flip the salmon and cook for an additional 3 minutes until the salmon is opaque and flakes easily with a fork. Remove from skillet and keep warm.
  5. Step 5: In the same skillet, add 1 tablespoon olive oil and 3 minced garlic cloves. Sauté over medium heat for 1 minute until fragrant.
  6. Step 6: Add 6 cups fresh baby spinach to the garlic oil and cook, stirring frequently, for 2-3 minutes until wilted but still bright green. Season with remaining 1/2 teaspoon sea salt and 1/4 teaspoon black pepper.
  7. Step 7: Plate the salmon fillets alongside a generous scoop of sweet potato mash and garlic spinach. Drizzle 1 tablespoon fresh lemon juice over the salmon before serving.
