Creamy Broccoli Casserole

Step 1: Preheat the oven to 180°C/350°F.

Step 2: Mix the topping ingredients in a bowl with a pinch of salt and pepper. Set aside.

Step 3: Melt the butter in a large pot over medium heat. Add the garlic and cook for 1 minute.

Step 4: Add the flour and cook for 1 minute, stirring constantly.

Step 5: Whisking continuously, slowly pour in half the milk. Once it is fully incorporated, whisk in the remaining milk and the chicken broth.

Step 6: Cook for 4–5 minutes, whisking occasionally and more often toward the end, until the sauce thickens enough to coat the back of a wooden spoon and a line drawn through it with your finger stays in place.

Step 7: Turn off the heat, add the cheeses and stir them in. Taste the sauce and add a little salt if needed.

Step 8: Add the broccoli and stir well to coat.

Step 9: Pour the mixture into a casserole dish and pat it down to fill the dish. Sprinkle over the topping, cover with foil and bake for 25 minutes.

Step 10: Remove the foil and bake for a further 20 minutes, until the topping is deep golden and the broccoli is tender.

Step 11: Let the casserole stand for 5 minutes before serving.
