How to Make Broccoli and Cauliflower Gratin
This recipe only takes about 30 minutes from start to finish! That’s the kind of recipe I like. And yes it’s covered in cheese, but it’s filled with broccoli and cauliflower, so I’m going to call it healthy (ish) and feel really good about eating it!
Here’s the basic process:
- Make the breadcrumb topping by chopping up the bread in a food processor.
- Cut cauliflower and broccoli into small florets, and boil them for about 3-4 minutes to soften them up slightly.
- Make the cream sauce by combining and cooking all sauce ingredients in a skillet.
- Stir the cauliflower, broccoli, and cheese into the cream sauce.
- Pour the broccoli/cauliflower/sauce mixture into the baking dish and sprinkle the bread crumbs on top.
- Bake for 15-20 minutes at 425°F.
It will come out hot, creamy, cheesy, bubbly, and a little bit crispy thanks to the breadcrumb topping. Yum! Check the recipe card at the bottom of this post for more detailed instructions.
Can you freeze cauliflower gratin?
You can freeze this broccoli and cauliflower gratin if you want to prepare it ahead of time or just save leftovers. I wouldn’t recommend this as something to freeze since it will change the texture of the broccoli and cauliflower, but it is definitely doable. Just cover the dish and freeze as you would a casserole. Then let it thaw in the refrigerator and bake when you’re ready to eat.
