For the Cauliflower
- 3-pound head of cauliflower, cut into large florets

For the Cheese Sauce
- 3 tablespoons unsalted butter
- 3 tablespoons all-purpose flour
- 2 cups milk
- 1 sprig fresh thyme, plus more to garnish

How to Make Creamy Baked Cauliflower Gratin
Step 1: Prepare the Cauliflower
Steam or boil the cauliflower in salted water until firm but tender, about 5 to 6 minutes. If boiling, salt the water well and drain very carefully in a colander.
Step 2: Preheat the Oven
While the cauliflower is cooking, preheat your oven to 375°F (190°C) and grease your casserole dish.
Step 3: Make the Cheese Sauce
Melt the butter in a medium saucepan over medium heat.
1. Add the flour and whisk until it turns a nice tan brown roux.
2. Gradually add splashes of milk while whisking. Start with a small amount until you have a paste-like consistency before adding more milk gradually.
3. Once all milk is added, stir in thyme, nutmeg, salt, and pepper. Boil while whisking constantly until thickened to resemble heavy cream.
Step 4: Combine Ingredients
Off the heat, stir in both cheeses (Parmesan and half of Gruyère) into your white sauce until melted and combined.
Step 5: Assemble the Gratin
Spoon some cheese sauce into the bottom of your prepared casserole dish.
1. Layer in the cooked cauliflower florets.
2. Pour over remaining cheese sauce evenly on top.
3. Sprinkle breadcrumbs and remaining Gruyère over everything. Garnish with additional thyme if desired.
Step 6: Bake Your Gratin
Place in the top third of your preheated oven and bake for about 30 minutes until golden brown on top. Serve hot or at room temperature for an enjoyable side dish!

- Adjust Cheese Varieties – Experiment with different cheeses like cheddar or mozzarella for unique flavors.

Common Mistakes to Avoid
Making a Creamy Baked Cauliflower Gratin can be easy, but there are common pitfalls. Here are mistakes to watch out for:
- Overcooking the Cauliflower: If you cook the cauliflower too long, it will become mushy. Aim for firm yet tender florets before baking.

- Not Preheating the Oven: Baking in a cold oven can lead to uneven cooking. Always preheat your oven to ensure the gratin bakes properly.
- Using Low-Quality Cheese: The quality of cheese makes a difference. Opt for good Gruyère and parmesan for rich flavor.
