Cheesy Bacon Keto Broccoli Cauliflower Casserole is a delicious, low-carb dish that works equally well as a side or a main course. This broccoli cauliflower casserole transforms simple vegetables into a family-friendly favorite — cheesy, savory, and topped with crisp bacon for extra flavor.
This bacon broccoli casserole is full of texture and taste. Tender steamed florets of broccoli and cauliflower are combined with a creamy cheese sauce, finished with plenty of melted cheddar and Colby Jack. The salty crunch of bacon balances the richness and makes the casserole irresistible to both kids and adults.
Keto Broccoli Cauliflower Casserole
Casseroles are a go-to in our kitchen because they’re quick to assemble and satisfying to serve. Whether you want a lighter meal or a comforting side, this recipe delivers. Serve it alongside your favorite protein or enjoy it on its own for a simple weeknight dinner.
Fresh or Frozen Vegetables for This Bacon Broccoli Bake
Fresh broccoli and cauliflower are great for this casserole; I steamed them until just fork-tender. If you prefer frozen vegetables, they work fine too — simply thaw them and skip the steaming since they’re typically pre-cooked. Both options produce a tasty casserole, so use whatever you have on hand.
Adding Meat to the Broccoli Bake
If you’d like a heartier dish, add cooked shredded or chopped chicken, cooked ground beef, or cooked turkey. Any of these proteins mix well with the creamy cheese base and make the casserole a more substantial main course.
What Is the Sauce in This Keto Casserole?
The sauce is a simple blend of sour cream and heavy cream seasoned with mustard, garlic, paprika, salt, and pepper. Shredded sharp cheddar and Colby Jack cheeses are folded in to create a rich, creamy binder for the broccoli and cauliflower.

How to Store Leftovers
Let the casserole cool to room temperature, then cover and refrigerate. Stored in an airtight container, leftovers will keep 3–4 days in the fridge. Use your best judgment and discard any food that smells off or shows signs of spoilage.
Freezing This Creamy Broccoli Casserole
This casserole is not ideal for freezing. The heavy cream and dairy can change texture when thawed, sometimes becoming slightly grainy or curdled. For best results, prepare and refrigerate only the amount you plan to eat within a few days.
Is This Casserole Gluten Free?
Yes. The recipe uses no flour or gluten-containing ingredients, making it suitable for a gluten-free, low-carb, ketogenic diet. It’s a comforting dish that still fits a keto lifestyle.
Scaling the Recipe
You can halve the recipe if you want a smaller portion, or double it to feed a crowd. This casserole adapts well for family dinners or holiday gatherings and is easy to customize to your tastes.
