Step 1

Preheat the oven to 350 degrees F.

Step 2

Shave the brussels sprouts horizontally into 1/8-inch slices with a sharp knife or mandoline. Add to a bowl. Add the Cheddar, flour, thyme, garlic and some salt and pepper to the bowl. Toss to combine. Add the mixture to an 8- by 8-inch baking dish, packing it in. Pour over the heavy cream.

Step 3

In a small bowl, combine the panko, Parmesan and oil and pour over the brussels sprouts mixture.

Step 4

Bake uncovered until the brussels sprouts are tender, the sauce is bubbling and the top is golden, 25 to 30 minutes. Garnish with the parsley and serve.
