Summary
- Comforting and Satisfying: This cauliflower casserole’s combination of tender potatoes and cauliflower with a golden, cheesy top is a comforting side dish that doesn’t feel like it’s too heavy on carbs.
- Versatile Dish: Perfect for both casual weeknight dinners and holiday occasions like Thanksgiving and Christmas or when you need to bring a dish to pass.
- Easy to Customize: Easily adaptable with different cheeses or vegetables, making it a flexible recipe.
- Healthy Twist: Uses cauliflower for a healthier twist on classic potato bakes without sacrificing flavor or texture.
Ingredients to make a cauliflower casserole
- 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!
Popular substitutions & additions
- Potatoes: Keeping in line with using starchy potatoes, sweet potatoes would be a great option, especially during the cooler months when sweet potatoes take the stage. Using a combination of regular and sweet potatoes would be okay as well.
- Vegetables: In addition to cauliflower, broccoli being similar in type and texture, would be a great addition.
- Cheese: Experiment with different sophisticated cheeses like shredded smoked gouda, Gruyère, Monterey jack, or fontina cheese.
- Herbs & Spices: Elevate the flavors more with rosemary, oregano, smoked paprika, or chives.

Tips for making the best cauliflower casserole
- 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.
- 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.
- 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.
- 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.

Can I freeze a casserole made from cauliflower?
You can, but the texture may change upon reheating, so I don’t recommend it if you’re serving for a big occasion and want it to have the best texture. Once cooled, transfer the casserole to a freezer-safe container with a lid. Store in the freezer for 2 to 3 months. Remove and thaw overnight in the refrigerator before reheating.
Reheating cauliflower casserole:
To reheat the casserole from fresh, preheat your oven to around 350°F. Cover the casserole with aluminum foil to prevent the cheese from burning, and heat it for about 15-20 minutes or until it’s warmed through.
Frequently Asked Questions
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.
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.
Yes! If you prefer to use only cauliflower and no potatoes that works just fine! I would double or triple the amount of cauliflower to make sure it’s a more hearty bite.
This cheesy cauliflower potato bake is a wonderful addition to any holiday table. Simple to make and cook, it’s lighter than other creamy and cheesy side dishes, but is just as delicious!

Never made anything like this before, but wow my daughter and I absolutely love it, we added broccoli too, tastes brilliant 👏
Yum, broccoli is a great addition! So happy you and your daughter loved the recipe. Thank you so much, Lena!!
Do you think I could steam the veggies instead?
I don’t see why you couldn’t! I just like the roasted flavor the oven adds to the dish. You’ll have to come back and let me know what you think after you make it!
You’re welcome and I’m going to be making it again this weekend,it’s one of our favorites!
Excellent – lots of fresh thyme and cheese – great way to reduce the carbs in the meal. They said make it again so I will print the recipe for my file. Thanks
So glad it was a hit!
Pretty bland as standard.
So sorry to hear that it was too bland, cauliflower is one of those foods that does take some getting used to.
Could you add bacon to this recipe?? If yes, would you recommend adding it before baking ?
You could! I would probably add it before baking, but I don’t eat bacon, so I’ve never cooked it.
Can you prepare in stages to shorten dinner cook time…like pre-Boil potatoes & cauliflower in the a.m. so you only have to bake in the p.m.?
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.
