Cheesy Cauliflower Gratin Ingredients
For the Cauliflower & Sauce
- Cauliflower florets – choose fresh, firm heads for the best texture in your Cheesy Cauliflower Gratin.
- Unsalted butter – melts smoothly to create a rich roux base for the creamy sauce.
- All-purpose flour – thickens the sauce perfectly without lumps when whisked in gently.
- Whole milk – use full-fat milk to keep the sauce luxuriously creamy.
- Garlic cloves – minced to add a subtle, aromatic kick that complements the cheese.
- Salt and pepper – season carefully to enhance all the flavors without overpowering.
For the Cheese Mixture
- Sharp cheddar cheese – melts beautifully and delivers that classic cheesy punch.
- Parmesan cheese – adds a nutty, savory depth that crisps up on top.
- Gruyère cheese (optional) – introduces a slightly sweet, gooey texture for extra richness.
For the Topping
- Breadcrumbs – sprinkle evenly for a golden, crunchy crust.
- Paprika – dust lightly to give a warm color and mild smoky flavor to the crust.
- Fresh parsley – chopped and scattered after baking for a fresh, vibrant finish.
How to Make Cheesy Cauliflower Gratin
- Preheat oven to 375°F and generously butter a 9×13-inch baking dish so the Cheesy Cauliflower Gratin won’t stick and bakes evenly with a golden crust.
- Blanch cauliflower in salted boiling water for 4 minutes, then drain and dry the florets thoroughly to preserve their tender-crisp texture before baking.
- Make roux by melting butter over medium heat, whisking in flour until it bubbles and turns pale gold, about 1–2 minutes for a smooth base.
- Whisk in milk gradually, stirring constantly until silky and thickened, about 5 minutes, then stir in minced garlic, salt, and pepper for savory depth.
- Add cheese to sauce off heat, folding in cheddar, Parmesan, and optional Gruyère until melted and velvety smooth for extra richness.
Assembly & Baking:
- Combine cauliflower and cheese sauce in the baking dish, tossing gently to coat each floret completely in the creamy mixture.
- Top gratin with an even layer of breadcrumbs, sprinkle paprika for color, and dot with a few extra cheese shreds for the ultimate golden crust.
- Bake at 375°F for 25–30 minutes until bubbling and the topping turns golden brown and crisp around the edges.
- Rest the gratin for 5 minutes before serving to allow the sauce to set and flavors to meld for perfect slices.
Optional: Add chopped fresh chives for a pop of color and fresh flavor.

Tips for the Best Cheesy Cauliflower Gratin
