Step‑by‑Step Instructions for Broccoli Cheese Casserole
  1. Steam broccoli florets in a microwave-safe bowl with water for about 5 minutes or on the stovetop using a steamer basket.
  2. Preheat your oven to 425°F (220°C) and grease an 11x7-inch baking pan with olive oil.
  3. Heat olive oil in a skillet, add sliced leeks and shallots, cook for 8-10 minutes until softened, then add minced garlic and sauté for 1-2 minutes.
  4. Pour in dry white wine, deglaze the pan and let evaporate for 2-3 minutes, then sprinkle in flour and stir for about 1 minute.
  5. Whisk in whole milk and simmer until the mixture thickens, about 4-5 minutes. Stir in salt, pepper, and cheddar cheese until melted.
  6. Fold in the steamed broccoli until thoroughly coated and pour the mixture into the baking pan.
  7. Combine remaining olive oil with panko breadcrumbs and sprinkle over the casserole. Bake uncovered for about 20 minutes until golden brown.
