Ingredients
2 tablespoons unsalted butter, plus more for greasing
Kosher salt
1 medium head cauliflower (about 2 ½ pounds), broken into medium florets
2 tablespoons all-purpose flour
1 cup heavy cream
¾ cup grated Gruyère cheese
½ cup grated fontina cheese
Freshly ground black pepper
¼ cup panko or bread crumbs
2 tablespoons pecorino or Parmesan
1 tablespoon chopped fresh thyme
1 tablespoon olive oil
Flaky sea salt, for serving (optional)
Preparation
- Step 1
Heat oven to 400 degrees and butter a 2-quart glass baking dish.
- Step 2
Bring a large pot of salted water to a boil and blanch the cauliflower until tender, about 5 minutes. Transfer to a colander to drain and cool.
- Step 3
In a small saucepan, melt the 2 tablespoons butter over medium heat. Stir in the flour until it forms a pale-golden paste, about 1 to 2 minutes. Stir in the heavy cream and bring the mixture to a low simmer, stirring frequently, until it thickens, about 2 to 3 minutes. Off heat, stir in half the Gruyère and fontina.
- Step 4
Pat the cauliflower dry then transfer it to a large bowl. Pour the creamy sauce over the cauliflower and stir to coat. Season generously with salt and pepper.
- Step 5
Transfer the cauliflower mixture to the buttered baking dish, spreading it in an even layer. Top with the remaining Gruyère and fontina. Bake until the mixture begins to bubble and the cauliflower starts to turn golden, about 20 minutes.
- Step 6
Meanwhile, in a small bowl, stir together the panko, pecorino, thyme and oil.
- Step 7
Spoon the panko mixture on top of the cauliflower and bake until the topping is crisp, about 10 minutes. Allow the casserole to cool for about 5 minutes or so, then serve. Season with flaky salt, if desired.

I roast the cauliflower with a touch of olive oil and garlic prior to using it in the caserole. I don't have to worry about water and the depth of flavor is wonderful.
I did a spreadsheet of ingredients to verify calorie counts: 1 cup cream, 414 calories 2 TBSP butter, 200 2 TBSP AP Flour, 56 1 TBSP Olive Oil, 120 1/4 Cup Parmesan, 110 2.5 Oz Fontina, 275 2.5 Oz Gruyere, 275 1/4 Cup Panko, 55 1 Head Cauliflower, 150 Total 1655 Calories; 275 calories if 6 servings, or 414 Calories if 4 servings
I totally cheat microwave cauliflower & let it drain until ready to use.
Couldn’t get fontina though I was willing. Gruyère and parmigiana is fine
This was a decent side dish, I will say though that the beautiful coloring on the picture for this recipe wasn't achieved on my end after crisping for 10 minutes. Saved to the recipe box for future tweaking.
Steam the cauliflower instead of blanching it.
