Sicilian-Style Cauliflower Casserole
Sicilian-Style Cauliflower Casserole

This recipe was inspired by a baked penne and cauliflower dish that was served to me by my Sicilian friend, Roberto. He called it simply, pasta al forno, which is the Italian term for food that is baked in an oven. I liked the combination of ingredients so much that I thought they could stand on their own without the carby pasta. He would definitely protest the omission; he believes that pasta is a basic human right and an essential part of every dinner.

But, I am not Sicilian, and I have fitness goals (namely to keep fitting into my favorite pair of jeans), so my rendition became this savory cauliflower casserole.

Eating cauliflower rice and cauliflower crust pizza has taught me that the mild flavor of the humble cauliflower can be a perfect replacement for starchy foods. When I made this dish, I didn’t miss the pasta at all, in fact, I preferred it without (don’t tell Roberto).

Roasting the cauliflower al forno makes it sweeter and juicier, and gives it a mildly nutty flavor. Garlic, briny capers, kalamata olives, a generous helping of fresh sage, and tangy lemon zest add the quintessential essence of Mediterranean cuisine. A pinch of crushed red pepper flakes gives it a welcome touch of heat, but you can leave them out, or, if you like things spicy, go ahead and add a little more. All of the ingredients are placed in a casserole dish and topped with mozzarella, Parmesan, and breadcrumbs before going into the oven. You’ll know it’s done when the cheese is melted and speckled golden brown. Just before serving, sprinkle the top with chopped fresh parsley, which adds color and balances the richness of the cheese.

This cauliflower casserole is hearty enough to be the centerpiece of a vegetarian dinner (Meatless Monday, anyone?). For more protein, pop it in the oven with these super simple Baked Chicken Breasts, and everything will finish cooking at the same time.

For a different take on this recipe, slice the cauliflower like bread into four ½-inch thick steaks (like we did in this recipe). Arrange the slices on a baking sheet coated with nonstick cooking spray, and drizzle them with 2 tsp. olive oil. Bake for 10 minutes, then flip each piece over and top evenly with the rest of the ingredients. Bake for 15–20 minutes more. The result is a dramatic – and satisfying – knife-and-fork meal.
