Final Notes for the Broccoli and Cauliflower Gratin Recipe
➡️ A vegetable gratin is one of the best food recipes when you want to eat a light meal. Each of us has a preferred recipe and, probably, everyone ate vegetable gratin at least once in life.
➡️ I cook pretty often vegetable casserole and vegetable gratin and use different vegetable combinations, fresh or frozen, depending on the ingredients that I have at hand.
➡️ On this page, I show you how to make broccoli and cauliflower gratin. One of my personal contributions to the classic gratin recipe is the salted cheese layer. Most often I use feta, but you can add other salted cheese types as well.
➡️ No matter which cheese are you using, it has to be grated or crushed into small pieces for better blending with the sour cream sauce. If you don’t have or you don’t like salted cheese simply add a layer of grated Parmesan, Cheddar, or another similar cheese type.
➡️ The second customization of the traditional recipe is the chives or green onion layer. This adds more aroma and refinement to the simple broccoli and cauliflower flavors.
➡️ The third thing that I make different from the classic gratin recipe is the sour cream sauce. By the technique that I use, you get a fantastic creamy texture that binds together all ingredients.
➡️ The broccoli and cauliflower gratin is served usually without any other side dish. However, you might cook it as a side dish and serve this vegetable gratin along with roasted, grilled, or baked meat such as roast chicken, grilled pork, baked sausage, and so on.
➡️ Increasing the intake of minerals, vitamins and fibers is the key to maintaining a healthy body, so the consumption of delicious vegetables such as cauliflower and broccoli is vital.
