(Full ingredient amounts and complete instructions available in the recipe card down below)

Grated cheddar cheese just added to white sauce in a saucepan with a whisk.

Make the cheese sauce by melting butter and whisking in flour (to create a roux). Then stir in the garlic, rosemary, salt, and pepper. Finally, add the cheese and whisk until a creamy sauce forms.

Important Tip: Prepare all the sauce ingredients (measuring, chopping, and grating) first before starting to make the sauce as the process is quick.

Pour the cheese sauce over the cauliflower florets that were placed evenly in a 8×10 casserole dish.

A quick note: Give the casserole dish a gentle shake side-to-side to evenly distribute the sauce. It’s okay if you don’t completely cover the tops of every cauliflower floret.

Looking for an easy vegetable side dish with delicious, creamy cheese and a crunchy topping? This cheddar cauliflower gratin recipe has got you covered.

Ingredients

For the vegetable:

  • 1 lb small cauliflower florets (similar size)

For the sauce:

  • 2 tbsp (1 oz) unsalted butter
  • 2 tbsp all-purpose flour
  • 1½ cups milk (I used 2%)
  • 2 garlic cloves, minced
  • 1 tbsp fresh rosemary, chopped
  • 1 cup sharp cheddar cheese, freshly grated
  • Salt and pepper, to taste

For the topping:

  • ½ cup panko breadcrumbs (or regular breadcrumbs)
  • ½ cup sharp cheddar

Instructions

  1. For the vegetable: Preheat the oven to 425 degrees F. Place the cauliflower florets in an 8x10 casserole dish. Set aside.
  2. For the sauce: In a small saucepan at medium heat, melt the butter, and then whisk in the flour until it is incorporated into the butter. Decrease the heat to medium-low.
  3. While whisking, slowly pour in the milk until the mixture is well-combined. Then stir in the garlic, rosemary, salt, and pepper and whisk for another minute.
  4. Add in the cheddar cheese. Whisk until the sauce thickens into a creamy, smooth sauce (it coats the back of a wooden spoon). Remove from heat. Pour the sauce evenly over the cauliflower.
  5. For the topping: In a small bowl, combine the breadcrumbs and cheddar together, then evenly sprinkle the cauliflower dish with it.
  6. Bake it: Cover the cauliflower gratin with aluminum foil and bake in the oven for 20 minutes. Remove the aluminum foil and then bake for another 20-25 minutes, until the top is golden-brown. Best served immediately.
