Ingredients

  • 1 cup sour cream
  • 1/2 cup cream cheese, softened
  • 1 1/2 cups shredded cheddar cheese, divided

  • 1 teaspoon garlic powder
  • 1/2 teaspoon onion powder
  • 1/4 teaspoon salt

  • Fresh parsley for garnish (optional)

Instructions

Step 1: Preheat & Prep

Preheat your oven to 375°F (190°C). Lightly grease a baking dish.

Step 2: Cook the Cauliflower

Steam or boil the cauliflower florets for 7–8 minutes, or until fork-tender. Drain well and pat dry with paper towels to remove excess moisture.

Step 3: Mix the Creamy Base

In a large bowl, mix together the sour cream, cream cheese, half the cheddar cheese, mozzarella, garlic powder, onion powder, salt, and pepper.

Step 4: Combine

Add the cooked cauliflower, half the crumbled bacon, and half the green onions to the creamy mixture. Stir gently to combine.

Step 5: Bake

Pour the mixture into the prepared baking dish. Top with the remaining cheddar cheese and bacon. Bake for 20 minutes, or until bubbly and golden.

Step 6: Garnish and Serve

Top with the remaining green onions and fresh parsley. Serve hot.

Perfect Pairings

  • Grilled steak, chicken, or pork chops
  • A crisp green salad
  • Roasted asparagus or Brussels sprouts

Tips for the Best Casserole

  • Dry the cauliflower thoroughly — too much moisture makes it watery.
  • Use block cheese and shred it yourself for the best melt and flavor.
  • Customize the toppings with jalapeños, extra bacon, or different cheeses.

Flavor Variations

  • Spicy Kick: Add chopped jalapeños or a dash of hot sauce.
  • Vegetarian: Skip the bacon and add roasted mushrooms.
  • Herb Boost: Mix in fresh chives, thyme, or rosemary.

Make-Ahead & Storage

  • Make-Ahead: Assemble up to 1 day ahead. Cover and refrigerate, then bake just before serving.
  • Fridge Storage: Store leftovers in an airtight container for 3–4 days.
  • Reheat: Warm in the oven or microwave until heated through.
