ingredients & substitutions

  • Potatoes: Peel and chop the potatoes. Use starchy potatoes like Yukon Gold or Russet for the best results since they will absorb the milk and cheese; it’s best to avoid waxy potatoes.
  • Cauliflower: Cut the cauliflower into small florets. Boil them with the potatoes to soften before baking.
  • Seasonings: Salt, pepper, garlic powder and thyme.
  • Milk: Milk helps to keep the cauliflower and potatoes from drying out when they are baked and adds a creamy flavor. You could use 2% milk for as suggested here or half and half for a more decadent side dish.
  • Cheese: The casserole is topped with shredded cheddar cheese before being baked but any melty cheese will work!

Tips for making the potato bake

  1. Cut the potatoes and cauliflower into similar sized pieces. This will help them to cook through at the same time so that the casserole has an even texture.
  2. Start the potatoes in boiling water. If you place the potatoes into cold water and bring it up to a boil, the outsides will be cooked before the middles. Cook them in salted water to add flavor right from the beginning of cooking.
  3. Let the cauliflower potatoes steam and drain. This will help to get rid of excess moisture. If you add them straight to the casserole dish they can get too soggy.
  4. Change up this recipe to suit your tastes. Try using sweet potatoes instead of regular, and broccoli works great in place of the cauliflower. You can use different seasonings depending on what you are serving it with.

Frequently Asked Questions

Can you make this recipe with plant based milk?

We use 2% dairy milk in this potato cauliflower bake, but you can use a neutral tasting plant based milk like oat milk or unsweetened almond.

Can you make it ahead of time?

For best results, this is best served as soon as it’s baked, but you can prep it ahead of time. You can boil the cauliflower and potatoes, place them in the dish with the milk and cheese, then keep covered until you are ready to cook them later in the day.

If you do have leftovers, they will keep well in the fridge for 3 to 4 days and can be reheated in the oven at 350F until warmed through.

What do you serve it with?

This cauliflower potato casserole can be easily served as part of an easy weeknight meal, but it will not be out of place on your Thanksgiving or holiday table either. Serve them alongside:
Thanksgiving Turkey
Mushroom Gravy
Green Beans with Almonds
Cranberry Orange Sauce
