Ingredients

Instructions

  1. Step 1: Preheat the oven to 425°F (220°C). Peel and dice 2 medium sweet potatoes into 1-inch cubes, toss with 1 tbsp olive oil, 1/2 tsp sea salt, and 1/2 tsp black pepper, then spread evenly on a baking sheet. Roast for 25-30 minutes, flipping halfway, until tender and caramelized at edges.
  2. Step 2: While the sweet potatoes roast, trim and rinse 200 g green beans. Toss with 1 tbsp olive oil, 1/4 tsp sea salt, and spread on a second baking sheet to roast in the oven alongside sweet potatoes for the last 12 minutes until crisp-tender.
  3. Step 3: Pat dry 2 chicken breasts and season both sides with 1/2 tsp sea salt and 1/4 tsp black pepper. Heat 1 tbsp olive oil in a large skillet over medium-high heat. Add the chicken breasts and cook for 6-7 minutes per side until the internal temperature reaches 165°F (74°C) and the exterior is golden brown.
  4. Step 4: In the last 2 minutes of cooking chicken, add 3 minced garlic cloves and 1 tsp chopped fresh rosemary to the skillet. Sauté until fragrant, about 1 minute, spooning the aromatic oil over the chicken.
  5. Step 5: Remove chicken from heat and drizzle with 1 tbsp fresh lemon juice. Serve chicken alongside roasted sweet potatoes and green beans, spooning any pan juices over the top.
