Creamy Cauliflower Casserole (Vegan, Gluten Free).

This creamy cauliflower casserole is a cozy and comforting gluten free and vegan side dish that everyone will enjoy. A crunchy breadcrumb topping is a delicious contrast to the flavorful sauce.

Cauliflower casserole might not be the first thing that comes to mind when you think of a holiday side dish. I love cauliflower for everyday meals – it’s delicious roasted or in a vegetable curry.

But I thought it would be nice to dress it up a little bit for the holidays – cook it in a creamy sauce, similar to scalloped potatoes, and top it with delicious buttery breadcrumbs. This creamy cauliflower casserole is easy to make, and special enough for any holiday meal.

If you happen to have a nightshade allergy or sensitivity, potatoes are off limits for you, and cauliflower can be a good substitution. You can easily make mashed cauliflower, but if you want to take it up a notch, try this vegan cauliflower casserole. Your guests will thank you!

Should I use fresh or frozen cauliflower in this cauliflower casserole?

You can use either! Fresh or frozen cauliflower will work well in this recipe.

What type of gluten free flour should I use to thicken the sauce?

You should be able to use whatever brand of gluten free flour that works for your dietary needs. I used Namaste Perfect Flour Blend. If you don’t have a blend that works, you could also try tapioca starch.

What kind of dairy free milk should I use to make a cream sauce?

Any neutral tasting dairy free milk should work well. I used So Delicious Unsweetened Coconut Milk in this recipe. You could use soy milk or almond milk if those work for you. Flax milk or rice milk are also options.

How to make vegan creamy cauliflower casserole:

1. Cook chopped onion in vegan buttery spread until tender. Stir in the gluten free flour blend.
2. Add half of the dairy free milk and stir. Add the spices and continue stirring, then add the remainder of the milk. Cook over medium high heat until the sauce thickens.
3. Pour the sauce over the cauliflower and bake at 350 degrees for about 90 minutes.
4. Add the gluten free breadcrumbs for the last 20 minutes of the baking time.

What brand of gluten free breadcrumbs should I use?

If you have a brand of gluten free breadcrumbs that works for your diet, go ahead and use that. Otherwise, I recommend making your own breadcrumbs from gluten free bread. You can look into brands like Schar, Canyon Bakehouse, or BFree to see if you can find a bread that works for you.

Can I make gluten free breadcrumbs ahead of time?

Yes, you can make the breadcrumbs the day before making this casserole. You could even make a large batch of breadcrumbs and then store them in the freezer so you have them when you need them.
