Ingredients

Instructions

  1. Step 1: Preheat oven to 425°F. Toss 1 medium cauliflower head cut into florets with 2 tbsp olive oil, 1 tsp sea salt, and 1/4 tsp black pepper on a baking sheet. Roast for 25-30 minutes, stirring halfway, until golden and tender.
  2. Step 2: While cauliflower roasts, heat remaining 2 tbsp olive oil in a large skillet over medium heat. Add 4 thinly sliced garlic cloves and sauté for 1-2 minutes until fragrant but not browned.
  3. Step 3: Add 10 cups fresh spinach leaves to the skillet in batches, stirring continuously until wilted and bright green, about 3-4 minutes. Season with 1/2 tsp sea salt and 1/4 tsp black pepper.
  4. Step 4: Remove skillet from heat, drizzle 2 tbsp fresh lemon juice over the spinach, and toss gently to combine. Serve the garlic spinach alongside the roasted cauliflower for a fresh, vibrant side dish.
