Instructions

  1. Step 1: Preheat the oven to 425°F. Peel and dice 2 medium sweet potatoes into 1-inch cubes. Toss with 1 tbsp olive oil, 1/2 tsp sea salt, and 1/4 tsp black pepper, then spread evenly on a baking sheet. Roast for 25-30 minutes until tender and edges are slightly caramelized.
  2. Step 2: Meanwhile, pat dry 2 boneless skinless chicken breasts and season both sides with 1/2 tsp sea salt, 1/4 tsp black pepper, and 1 tbsp fresh thyme leaves. Heat 2 tbsp olive oil in a large skillet over medium-high heat. Add the chicken and sear for 6-7 minutes per side until golden brown and internal temperature reaches 165°F.
  3. Step 3: While chicken cooks, mince 3 garlic cloves. Remove chicken from skillet and set aside covered to rest. In the same skillet, add 1 tbsp olive oil and minced garlic, sauté over medium heat for 1 minute until fragrant but not browned.
  4. Step 4: Add 5 cups fresh spinach to the skillet with garlic, sprinkle with a pinch of salt, and sauté for 2-3 minutes until wilted but still vibrant green. Remove from heat.
  5. Step 5: Slice the rested chicken breasts, drizzle with 1 tbsp fresh lemon juice, and serve alongside roasted sweet potatoes and sautéed spinach for a balanced Whole30-compliant plate.
