The Ingredients

The full list of ingredients and amounts can be found in the recipe card at the bottom of the post.

I prefer to use real mayonnaise as I don't like Miracle Whip (there is just something about the flavor).

I use sharp cheddar cheese for this recipe as I feel it has the most intense flavor and blends well with the mustard and mayonnaise.

I use Dijon mustard because it has the best flavor to add a kick to the cauliflower (which tends to be bland).

Step By Step Instructions

Step1: Preheat oven to 375F degrees.

Step2: Place the cauliflower in a rectangular baking dish (about 9x13 or 8x11).

Step3: Mix the mustard and mayonnaise together in a bowl. Spread the mixture on top of the cauliflower. Use your hands to mix it together well.

Step4: Sprinkle cheese on top and drizzle about 1 tbsp. of olive oil over the cheese.

Step5: Bake, covered, for 50-60 minutes until cheese is melted and lightly browned, and cauliflower can be pierced with a fork. You can remove the cover during the last 10-15 minutes to help the cheese brown.

NOTE: The browned crispy pieces of cheese are the best parts of this dish.

Expert Tips

If the cheese isn't browned enough, pop it under the broiler for a minute or two to crisp it up;
I don't recommend using grainy Dijon mustard as the texture is not great in the cauliflower bake;
Remove the cover during the last 10-15 minutes of baking to brown the cheese.

Common Questions

Can I make this recipe in advance?

Absolutely! Prepare the whole casserole and store it covered in the fridge overnight. Bake according to instructions.

What kind of cheese is best for cheesy cauliflower?

Sharp cheddar is my go-to for its bold flavor, but pepper jack or a milder cheddar also work great.

Storing Instructions

Yes!

To freeze before baking: Wrap tightly in freezer-safe plastic wrap and foil. Store for up to 3 months. Thaw overnight and bake as directed.
To freeze after baking: Wrap and freeze for up to 3 months. Thaw overnight and reheat in a 350°F oven for 10–15 minutes, until hot and melty.
