Cauliflower Romanoff
Gluten Free Living – 2025
Cauliflower Romanoff is a terrific way to enjoy cauliflower. This easy recipe includes cooked, mashed cauliflower along with sour cream, lots of sharp Cheddar cheese, green onions and a little bit of paprika to give it some flavoring/heat. It’s based off one of my favorite potato casserole recipes, but using cauliflower instead. While I mashed the cauliflower, if you prefer to keep it in chunks, that will also work.

Back in late September, our church’s community group gathered together for dinner one Wednesday night. I brought Honey Mustard Baked Chicken and this tasty vegetable along with a batch of English Lemon Shortbread Strips. All the others in the group brought different meat, sides, salads and desserts as well. It was truly potluck and fantastic!
Friends sometimes ask me where I get different recipes. A lot of recipes, like this one, are do-overs from other recipes using different ingredients. I’ve made this basic recipe with regular potatoes, sweet potatoes, rutabagas and now cauliflower. Because it’s made in advance it’s marvelous for company dinners or holidays when you have a lot going on.
If you’re trying to cut down on starches, Cauliflower Romanoff is a delightful way to enjoy a cauliflower casserole.

Cauliflower Romanoff is a fantastic side dish for holiday dinners.

I served it with Honey Mustard Baked Chicken.

If you prefer a different texture, you can keep the cauliflower in florets instead of mashing.
Here’s what I did.

I used these ingredients.

Wash cauliflower and place in a large stock pot filled with water.

Bring to a boil over medium-high heat and boil cauliflower until fork tender.

Drain cauliflower in a colander.

Return cauliflower to stock pot and mash with a potato masher.

Completely mash the cauliflower (or if preferred, don’t mash the vegetable, just boil it until tender).

Add cheddar cheese, sour cream and a full bundle of green onions.

Sprinkle with salt and pepper.

Stir well to combine.

Place in a greased 9×13″ glass baking dish.

Top with additional cheddar cheese; sprinkle very generously with paprika. Cover and refrigerate overnight.

Bake at 350 degrees for 30-40 minutes, until heated through. Sprinkle with an additional chopped green onion.

Serve hot!

If you prefer a thicker texture for the cauliflower, keep it in florets instead of mashing.

Cauliflower Romanoff tasted wonderfully with Honey Mustard Baked Chicken.
