Ingredients Notes

The secret to this Loaded Cauliflower Casserole lies in its carefully selected ingredients. Here’s what you’ll need and why each item is essential.
- Cauliflower: The star of the dish! Use a large head of fresh cauliflower, cut into bite-sized florets. If you’re short on time, pre-cut florets work too. Roasting them before assembling the casserole ensures they’re tender and flavorful.
- Bacon: Crispy, crumbled bacon adds a smoky, salty kick. For the best results, cook your bacon until it’s extra crispy, then chop it into small pieces.
- Cheddar Cheese: Sharp cheddar provides that classic cheesy flavor. Feel free to mix it with Monterey Jack or Gruyere for a more complex taste.
- Cream Cheese: This creates the creamy, velvety base for the casserole. Soften it beforehand to make mixing easier.
- Sour Cream: Adds tanginess and keeps the dish moist without being heavy. You can substitute Greek yogurt if you prefer.
- Green Onions: For a pop of freshness and a bit of mild onion flavor. Reserve some for garnish to make the dish look as good as it tastes.
You’ll also need basic pantry staples like salt, pepper, and garlic powder for seasoning. A large baking dish and a mixing bowl are all the special equipment you’ll need!
How To Make This Loaded Cauliflower Casserole

Creating this decadent dish is surprisingly simple. Let’s walk through the steps together.
Step 1: Roast the Cauliflower
Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper. Spread the cauliflower florets in an even layer, drizzle with olive oil, and season with salt and pepper. Roast for 20-25 minutes until tender and lightly golden.
Step 2: Prepare the Creamy Base
While the cauliflower is roasting, mix the softened cream cheese, sour cream, shredded cheddar cheese, garlic powder, and a pinch of salt in a large bowl. Stir until smooth and well combined.
Step 3: Combine and Assemble
Remove the roasted cauliflower from the oven and reduce the oven temperature to 375°F (190°C). Toss the cauliflower with the creamy mixture until it’s evenly coated. Transfer the mixture to a greased baking dish.
Step 4: Add the Toppings
Sprinkle the crumbled bacon and an extra layer of shredded cheese on top. For an added crunch, you can also sprinkle on some crushed pork rinds or almond flour.
Step 5: Bake and Serve
Bake the casserole for 20-25 minutes until bubbly and golden brown. Garnish with chopped green onions before serving. It’s ready to steal the show at your dinner table!
Storage Options
This Loaded Cauliflower Casserole is just as good the next day – if not better! Here’s how to store and reheat it for maximum freshness.
- Refrigeration: Store leftovers in an airtight container in the fridge for up to 4 days.
- Freezing: While the texture of the cauliflower may soften slightly, this casserole freezes well. Wrap it tightly in plastic wrap and foil, then freeze for up to 2 months.
- Reheating: Warm individual portions in the microwave for 1-2 minutes. To reheat the entire casserole, cover it with foil and bake at 350°F (175°C) for 20-25 minutes.
Variations and Substitutions
The beauty of this dish is its adaptability. Here are some creative twists to try:
- Vegetarian Option: Skip the bacon and add roasted mushrooms or sautéed spinach for a hearty meat-free version.
- Spicy Kick: Mix diced jalapeños or a pinch of cayenne pepper into the creamy base for a bit of heat.
- Extra Veggies: Add steamed broccoli, diced bell peppers, or zucchini to make it even more colorful and nutritious.
- Cheese Swap: Experiment with different cheeses like Gouda, Parmesan, or pepper jack for a unique flavor profile.
- Keto Boost: Top the casserole with crushed pork rinds instead of breadcrumbs for extra crunch.
