This delicious Loaded Cauliflower Casserole is a rich, cheesy low-carb dish that works equally well as a comforting main or a crowd-pleasing holiday side. It captures the familiar flavors of a loaded baked potato—cheese, sour cream, bacon and green onions—without the starch, making it a perfect option for keto dinners or holiday menus.
The combination of cream cheese, sour cream and shredded cheese creates a silky, creamy base while crisp, salty bacon adds a satisfying crunch. This casserole pairs beautifully with roasted or grilled meats such as chicken, ham, pork chops, turkey or steak, and it also makes a tasty accompaniment to other festive sides.
Cauliflower Casserole With Cream Cheese
This creamy cauliflower bake is simple to prepare and full of cozy, familiar flavors. The tender cauliflower is enveloped in a cheesy mixture, topped with more cheese and bacon, then baked until golden and bubbly.
Serve it as a hearty side or enjoy it as a satisfying main for a low-carb meal. It’s also easy to adapt—add cooked chicken or broccoli for more substance, swap in different cheeses, or use turkey bacon for a lighter option.
Ingredients
- Cauliflower – fresh heads cut into florets (or thawed, well-drained frozen cauliflower)
- Cream cheese – softened
- Sour cream – full fat preferred for best texture
- Colby Jack cheese – shredded and divided (or use cheddar, mozzarella or your favorite melting cheese)
- Bacon – cooked and crumbled
- Green onions – thinly sliced and divided (or chives)
- Garlic – minced fresh cloves (or 1/2 teaspoon garlic powder)
- Salt and pepper
- Paprika – for sprinkling
Substitutions & variations: Use turkey bacon to lighten the dish. Add chopped cooked broccoli, leftover chicken or cooked rice for a heartier casserole. Cheddar or mozzarella both melt well if you prefer them over Colby Jack.
Can I Use Frozen Cauliflower?
Yes. If using frozen cauliflower, thaw it completely and pat dry to remove excess moisture before combining with the cheese mixture to prevent a watery casserole.
How To Make Loaded Cauliflower Bake
STEP ONE – Preheat the oven to 375°F (190°C). Grease a 9×13-inch baking dish.
STEP TWO – Steam the cauliflower florets until tender, about 5–7 minutes. Drain thoroughly and pat dry with paper towels.
STEP THREE – In a large bowl, beat together the cream cheese, sour cream, 1 cup of shredded Colby Jack, half the crumbled bacon, half the green onions, minced garlic, salt and pepper until smooth.
STEP FOUR – Add the drained cauliflower to the bowl and gently fold until well coated with the cheese mixture.
STEP FIVE – Transfer the cauliflower mixture to the prepared baking dish and spread evenly.
STEP SIX – Top with the remaining 1 cup of shredded cheese, the rest of the crumbled bacon and a light sprinkle of paprika.
STEP SEVEN – Bake for 20–25 minutes, until the cheese is melted, bubbly and the edges are lightly browned.
STEP EIGHT – Remove from the oven and let the casserole rest for 5 minutes.
STEP NINE – Garnish with the remaining green onions and serve warm.
Handy tip!
For quick steaming, place cauliflower florets in a microwave-safe bowl with 2 tablespoons of water, cover, and microwave 5–7 minutes until tender. Drain and pat dry before mixing.
Can I Make This Casserole Ahead Of Time?
Yes. Assemble the casserole, cover tightly with plastic wrap or foil, and refrigerate for up to 24 hours. When ready to serve, remove the cover and bake as directed, adding a few extra minutes if the dish is cold from the fridge.
