Cauliflower Gratin Recipe …creamy cauliflower casserole

This cauliflower gratin recipe is a tasty way to add cauliflower to your diet. It’s not the healthiest cauliflower recipe but it’s probably healthier than cauliflower ice cream, if there is such a thing.
This French inspired cauliflower gratin recipe is basically a veggie cheese casserole. I like to put creamy horseradish sauce in mine, and you should definitely give that a try. I also like to add a few other veggies, just for color. I use red bell pepper, celery, and green onion in the video, but use whatever vegetables have in the fridge to add a bit of color; using just a little shredded carrot will add some pizzazz.

What You Need To Make a Cauliflower Gratin

2 lbs CAULIFLOWER florets
1 cup chopped veggies …like:
….but use whatever you have
2 cups whole MILK (or half and half)
5 Tbsp FLOUR
1-2 cups freshly grated CHEESE
(I like using a combo of cheeses, some of my faves are
swiss, parmesan, gruyere, gouda, and havarti)
1 Tbsp CREAMY HORSERADISH (or 2 Tbsp?…it’s good in this dish)
1 Tbsp fancy MUSTARD
SALT and PEPPER (to taste)

How to Cook Cauliflower Gratin

  • Cut the cauliflower into florets.
  • I like to steam the florets for 2-3 minutes, this will make the cauliflower gratin creamier. Use a steaming basket, or just place half an inch of water in a pan, cover, and steam that way for a few minutes. If you prefer your cauliflower a little firmer in your gratin,
    you can skip the steaming.
  • Lightly butter an oven safe baking dish.
  • Arrange the cauliflower florets on the bottom.
  • Add about 1 cup of assorted, chopped veggies on top, for color and added texture.
  • In a sauce pan, melt butter.
  • On medium heat, add in the flour with the butter and stir for about 1 minute.
  • Add in half the milk (or Half and Half), and continue stirring.
  • As the mixture thickens, add in the rest of the milk and whisk smooth.
  • Add in salt and pepper to taste, and dried Italian seasoning.
  • Add in half of the freshly grated cheese, stir until melted, and remove from the heat.
  • Evenly pour the creamy, cheesy mixture over the top of the cauliflower/veggie mix.
  • Top the gratin with the remainder of the cheese (although you can reserve a bit of cheese for topping at the end, if desired)
  • Bake 25-35 minutes in an oven pre-heated to 350 degrees Fahrenheit.
  • When the cauliflower gratin begins to color nicely on top, it’s ready.
  • Garnish with extra cheese or fresh herbs.

And that’s it.
