One of our favorite vegetable is cauliflower and we love to create new recipes with it. Give us a head of raw cauliflower and we can just sprinkle some salt, squeeze some lemon on the florets and eat it as a side. And this broccoli cauliflower casserole is an amazing vegetarian lunch that we make often during winter.

We already have a favorite cauliflower recipe that we make often and shared with you long time ago: Cheesy Cauliflower Recipe. We even made a video for it in case you need. This time we wanted to change things a bit though and came up with one of the best broccoli and cauliflower recipes.

We didn’t have enough cauliflower on the day we made this casserole, so we decided to make a combo of cauliflower and broccoli. They are from the same family, aren’t they?

We wanted this casserole to be really healthy and low-calorie, so we didn’t load it with cheese, just ½ cup was enough. If you like it more cheesy, you can increase the amount of cheese. It’s definitely up to you. Besides, this is a gluten-free broccoli cauliflower casserole recipe. No flour or no substitute for it is needed. Instead we added a combination of yogurt and milk in the egg mixture. This helps everything hold together, so you can slice it when serving.

How To Make

The recipe is quite simple. First, Steam or cook cauliflower and broccoli florets for 5-6 minutes, transfer them into cold water and drain. Meanwhile, whisk together an egg, milk, Greek yogurt, olive oil and cheese. Next, combine the wet mixture with the cooked broccoli and cauliflower florets and bake for about 40 minutes. Optionally, you can sprinkle little cheese over it and bake an extra 5 minutes or until slightly golden. Finally, top with crispy onions after it is baked.

Does it freeze well?

In addition to all of these, this broccoli cauliflower casserole freezes well, so you can prepare it ahead of time and reheat when you are in need of a tasty side dish to serve at a family dinner occasion. Why don’t you try it for the upcoming Thanksgiving?
