Ingredients

For the Cauliflower
- 8 cups cauliflower florets (about 3 pounds)
- 4 tablespoons butter
For the Cream Sauce
- 1/3 cup flour
- 3 cups milk (2 percent or whole)
- 1 cup Gruyere cheese, grated (Swiss is a great substitute)
- 1/2 teaspoon salt
- 1/4 teaspoon pepper
- 1/4 teaspoon nutmeg
For the Topping
- 1/2 cup panko crumbs (regular bread crumbs would work too)
- 1/3 cup Gruyere cheese, grated
- 1 tablespoon butter, melted
How to Make Baked Cauliflower Au Gratin
Step 1: Preheat the Oven
Preheat your oven to 375 degrees Fahrenheit. This ensures that your dish cooks evenly when placed inside.
Step 2: Prepare the Cauliflower
Separate the cauliflower into florets. You can either steam them for about 5 minutes or boil them in a large pot of water until just barely tender. Drain well and set aside.
Step 3: Make the Cream Sauce
In a saucepan, melt 4 tablespoons of butter over medium heat. Add 1/3 cup of flour and whisk until smooth; allow it to bubble gently.
– Gradually add in the milk while continuing to stir until thickened.
– Mix in 1 cup of grated Gruyere cheese along with salt, pepper, and nutmeg. Stir until melted; you want the sauce thick enough to coat the back of a spoon.
Step 4: Assemble the Dish
Pour one-third of the cream sauce into an au gratin baking dish (about 10 x 10 inches). If you use a larger dish, like 9 x 13 inches, know that your casserole will be thinner.
– Layer the par-cooked cauliflower on top of this sauce. Sprinkle lightly with additional salt.
– Pour the remaining cream sauce over the cauliflower evenly.
Step 5: Add Topping
In a small bowl, combine melted butter with panko crumbs and an additional 1/3 cup of grated Gruyere cheese. Mix well before sprinkling it generously on top of the cauliflower.
Step 6: Bake
Bake in your preheated oven for about 30 minutes or until the topping looks crispy golden brown and the cauliflower is tender throughout.

Common Mistakes to Avoid
One common mistake when making Baked Cauliflower Au Gratin is overlooking crucial steps in the preparation. Here are some pitfalls to watch out for:
- Skipping the steaming process: Not steaming or par-boiling the cauliflower can lead to crunchy florets. Always steam or boil until just tender for a perfect texture.
- Neglecting to season the sauce: Failing to add salt and spices can make your dish bland. Ensure you season the cream sauce well before combining it with the cauliflower.
- Using low-quality cheese: Cheap cheese melts poorly and can ruin your gratin. Opt for good quality Gruyere or Swiss cheese for a creamy and flavorful finish.
- Not baking long enough: A short baking time may result in an unappealing, undercooked top layer. Bake until golden and crispy for that delicious crunch.
- Overcrowding the baking dish: Packing too much cauliflower can lead to uneven cooking. Use a sufficiently sized dish to ensure even heat distribution.
