Ingredients Notes

The magic of this Loaded Cauliflower Casserole lies in its simple, flavorful ingredients. Each one brings something special to the dish, creating the perfect balance of texture and taste.
Cauliflower is the star of the show here. Roasting it before mixing it into the casserole enhances its natural sweetness and prevents it from becoming too watery. For the best texture, cut it into bite-sized florets and roast until lightly golden.
Cheese is what gives this dish its irresistibly gooey texture. A combination of cheddar and mozzarella works best—the cheddar brings sharpness, while the mozzarella melts beautifully to create a creamy consistency. You can also experiment with Monterey Jack or gouda for a twist.
Bacon adds that signature smoky, salty crunch that makes this dish truly feel "loaded." For the best results, use freshly cooked, crispy bacon instead of pre-packaged bacon bits. The flavor is unbeatable!
Sour cream and cream cheese work together to create a rich, velvety sauce that binds everything together. The tanginess from the sour cream balances the richness of the cheese, preventing the dish from feeling too heavy.
Green onions provide a fresh, mild onion flavor that complements the creamy and cheesy elements. Sprinkle them on top for a pop of color and flavor.
For this recipe, you’ll also need a large mixing bowl, a baking dish, and a sharp knife for prepping the cauliflower.
How To Make This Loaded Cauliflower Casserole

Creating this mouthwatering Loaded Cauliflower Casserole is easier than you might think. Let’s walk through the process step by step.
Start by prepping the cauliflower. Cut it into small florets and spread them on a baking sheet. Drizzle with olive oil, season with salt and pepper, and roast at 400°F for about 20 minutes, or until the edges are golden brown. This step ensures that your casserole won’t turn out watery.
While the cauliflower is roasting, prepare the creamy cheese mixture. In a large bowl, combine softened cream cheese, sour cream, shredded cheddar, and mozzarella. Mix until smooth and well combined.
Next, cook the bacon. If you haven’t already, fry up some bacon in a skillet until it’s perfectly crispy. Once it’s cool enough to handle, crumble it into small pieces.
When the cauliflower is ready, add it to the cheese mixture. Stir gently to coat every floret in that creamy, cheesy goodness. Then, fold in most of the crumbled bacon and some chopped green onions, saving a little for garnish.
Transfer everything into a greased baking dish and top with more shredded cheese. Bake at 375°F for about 15-20 minutes, or until the cheese is melted and bubbly.
Finally, remove the casserole from the oven and sprinkle the remaining bacon and green onions on top. Let it sit for a few minutes before serving so the flavors can meld together.
From start to finish, this dish comes together in about 40 minutes—perfect for a quick and satisfying meal.
Storage Options
If you have leftovers (which isn’t likely!), this Loaded Cauliflower Casserole stores beautifully for easy reheating.
To store in the refrigerator, transfer any leftovers to an airtight container. It will stay fresh for up to 4 days.
For freezing, let the casserole cool completely before wrapping it tightly with plastic wrap and aluminum foil. It can be frozen for up to 3 months. When ready to eat, thaw it overnight in the fridge before reheating.
To reheat, place a portion in the microwave and heat in 30-second intervals until warmed through. If reheating a larger portion, cover it with foil and bake at 350°F for about 15 minutes.
Variations and Substitutions
One of the best things about this Loaded Cauliflower Casserole is how adaptable it is. Here are some fun ways to change it up:
Want to make it a full meal? Add cooked shredded chicken or ground beef to the mix before baking for a protein-packed dish.
Looking for a different flavor profile? Swap the cheddar for pepper jack and add a dash of smoked paprika for a spicy kick.
Not a fan of sour cream? Substitute Greek yogurt for a slightly tangier, higher-protein option that still keeps the dish creamy.
For an even lower-carb version, try using broccoli instead of cauliflower. The flavors pair beautifully with the cheese and bacon.
Want extra crunch? Sprinkle crushed pork rinds on top before baking for a keto-friendly alternative to breadcrumbs.
No matter how you customize it, this Loaded Cauliflower Casserole is a foolproof way to enjoy a rich, satisfying dish while keeping things light. Give it a try tonight—you won’t be disappointed!
