Good ingredients are the foundation for a good meal! Here’s a little info to make sure you start off on the right foot!
Cauliflower — If you haven’t been able to tell, this veggie is quite possibly my favorite. It’s SO versatile, packed with vitamins and it’s super low carb, which is kind of my jam. At the store, choose heads that are totally white and firm, with no spots for this mashed cauliflower casserole.
Bacon — Who doesn’t love the salty, savory chewy -crispy amazingness of bacon?? It makes a wonderful topping in this loaded cauliflower casserole recipe, just make sure that you choose one that doesn’t have added sugar. Watch out for keywords like “brown sugar” or “maple”, the carbs are sky high, and you just don’t need them in this scrumptious dish.
Milk — I use a combo of plain almond milk and heavy cream in this recipe because it’s much lower in carbs than plain milk.
Green Onions — These mild onions, also called scallions, are high in vitamin K and their slightly sweet taste is a perfect companion to the bacon and cheese. Narrowly slice these all the way to the white.
Tools To Make
This roasted cauliflower casserole uses a few common tools, making this recipe even more terrific!!
- Pot – You’ll use a large heavy-bottomed pot both for blanching the cauliflower and making the cheese sauce.
- Casserole dish – I used a 9” cast iron pan, but you could also use a 9×13 casserole or baking dish. You want plenty of room so that these loaded cauliflower bites can be absolutely smothered in cheese and toppings.
Keep this loaded cauliflower casserole recipe in the refrigerator in an airtight container. Reheat in the oven or microwave for an almost-instant heartwarming meal.
Can You Freeze This?
You can freeze this cauliflower casserole to make dinner prep even easier. Prepare it all in the pan, then wrap in freezer plastic wrap and foil. Thaw in the fridge, or add a little baking time to take this side dish straight from freezer to oven.
Meal Prepping Tips
This plentiful, cauliflower casserole will make for several, unforgettable low carb dinners. Prepare as directed, then portion out into individual containers for a super quick meal!

Can I Add Squash?
You may be able to sneak in some rough cut yellow squash to this loaded cauliflower casserole because of its mild flavor.
But these yummy, healthy veggies deserve to be the star! Take this low carb squash casserole for a whirl, or try this pasta-like spaghetti squash casserole.
Can I Make This Spicy?
The cheesy sauce on this loaded cauliflower casserole recipe has a dash of Tabasco and black pepper, giving it more flavor than kick. If you want something a little stronger, up the Tabasco, sprinkle in some cayenne, or add your favorite spice mix.

- 2 Tablespoons Butter
- 3 cloves Garlic minced
- 1 Teaspoon Xanthan Gum
- 1/3 Cup Heavy Cream
- 1 1/2 Cup Milk I use unsweetened/plain almond milk to save carbs
- 1/2 Teaspoon Tabasco
- 4 Ounces Cream Cheese softened
- 2 Cups Shredded Cheddar divided
- 2 Teaspoons Kosher Salt
- 1/2 Teaspoon Black Pepper freshly ground
- 6 Slices Bacon cooked and crumbled
