Ingredients

Instructions

  1. Step 1: Preheat oven to 425°F. Toss 4 cups cauliflower florets with 2 tablespoons olive oil, 1 teaspoon sea salt, and 1/2 teaspoon black pepper until evenly coated. Spread in a single layer on a baking sheet.
  2. Step 2: Roast cauliflower in the preheated oven for 20 minutes until golden brown and edges are crispy, stirring halfway through.
  3. Step 3: While cauliflower roasts, heat 1 tablespoon olive oil in a large skillet over medium heat. Add 4 thinly sliced garlic cloves and 1/4 teaspoon red pepper flakes (if using). Sauté for 1-2 minutes until garlic is fragrant but not browned.
  4. Step 4: Add 3 cups fresh spinach leaves to the skillet and cook, stirring frequently, for 2-3 minutes until spinach wilts.
  5. Step 5: Remove roasted cauliflower from oven and add it to the skillet with spinach. Drizzle with 1 tablespoon fresh lemon juice and toss gently to combine.
  6. Step 6: Adjust seasoning if necessary and serve warm.
