Cheesy cauliflower casserole is perfect for low-carb and keto diets. Or just a great veggie dish. Make this today with these easy step-by-step photo instructions.
An easy lower-carb healthier version of "Cheesy Potatoes" using cauliflower. So now you can have "Crack Cauliflower Casserole." This really is a great side dish if you are doing any lower-carb diet for any reason.
This is one of those recipes I have done so many times that I never measure anything. But to write it down, I did measure tonight. It was the best one in a long time. Maybe I don't measure well just by sight.
In our old high carb days, we made "cheesy potatoes." This is the low-carb version of that. It's fast and easy. It also is made with things we usually have on hand.
Always excellent and tasty. Makes 4 servings and great for leftovers.
I have done this recipe for years. I usually buy frozen cauliflower in 1 pound bags and cook in the microwave per package instructions.
However, it is now hard to find one-pound bags. They are mostly 12 oz. So you may use that and decrease the other ingredients.
Can I use fresh cauliflower?
Yes. One medium head of cauliflower (about 2 pounds) will trim out to about 1 pound of well-trimmed florets.
You should precook the fresh cauliflower in a microwave. Place the cauliflower florets in a large microwave-safe bowl with a couple of tablespoons of water. Cover bowl loosely but not tightly. Cook on high until tender, 4 to 5 minutes, then drain.

Bacon is a great addition to this but not really necessary. Just cook 2-3 slices of bacon, crumble, and add to the casserole during mixing.
📖Low Carb Recipes
Use frozen cauliflower. See discussion for using fresh cauliflower.
Cook the entire bag of cauliflower in the microwave. I use a covered dish with about a tablespoon of water on the "frozen vegetable" setting. Or follow instructions on the package. You can use fresh cauliflower. One medium head should yield about one pound and cook in a microwave in 4-5 minutes with a bit of water.
Slice 3 green onions.
Move cauliflower to the mixing bowl and mash with a potato masher. You could also use a mixer or food processor, but you are NOT trying to cream this. Add cheddar cheese, sour cream, scallions, salt, and pepper. Bacon is optional.
Mix well and move to a baking pan. I usually use a 7 X 10 Corning Ware dish. It may be refrigerated or cooked now. Cook in preheated oven 375° convection until the top is browned. About 20 minutes. (you may adjust the temp depending on your needs for timing or cooking with other foods)
Try to let sit for 5 minutes before serving. Heat leftovers in the oven. Much better than microwaved.
