Broccoli & Cauliflower Casserole

No ratings yet

Bake this warm, wintry veggie casserole for a healthy and comforting dish.

Imagine that inside your warm baking dish, fresh from the oven, covered with a cheese crust, are two vegetables rich in nutrients. Broccoli is an excellent source of vitamin C, while cauliflower is rich in vitamins C, K, and manganese. Both are top sources of insoluble dietary fiber. And the health benefits don’t end there, because sprinkled abundantly among the vegetables is grated Parmigiano Reggiano, or Italian Parmesan, which is rich in calcium and protein.

This recipe is easy to prepare. It cooks low and slow for about two hours, so that you can enjoy time with family or do errands around the house while it bakes. As the flavors mingle in your oven, your home will be filled with a earthy, scrumptious aroma! When it’s finished you can serve it as a delicious vegetarian main dish, or as a side that complements any number of main entrees. Leftovers can be kept refrigerated, for a warm, hearty lunch the following day.

So, go ahead and dig in to this delicious cheesy casserole. Choose high quality cheese and fresh vegetables, and this cheesy, gooey casserole won’t leave you feeling guilty. We like to top this dish with a quickly melting low-fat cheese. With this recipe in your repertoire, you are in for a cheesy, comforting treat!
