Ingredients You’ll Need
- 1 large head of cauliflower, cut into florets
- 4 oz cream cheese, softened
- ½ cup sour cream or plain Greek yogurt
- 1½ cups shredded cheddar cheese
- 1 cup shredded Monterey Jack or Colby Jack cheese
- ½ cup grated Parmesan cheese
- 6 slices bacon or turkey bacon, cooked and crumbled
- 3 green onions or chives, thinly sliced
- 1 tsp garlic powder
- 1 tsp onion powder
- 1 tbsp ranch seasoning (optional for extra flavor)
- Salt and pepper to taste
Step-by-Step Instructions
1. Steam or Roast the Cauliflower
Begin by steaming the cauliflower florets for 8–10 minutes until tender but not mushy. Alternatively, roast them at 400°F for 15–20 minutes for a slightly nuttier flavor and firmer texture. Let them cool for a few minutes before mixing to avoid a watery sauce.
Pro Tip: Roasting brings out more flavor and prevents sogginess.
2. Prepare the Creamy Cheese Base
In a large mixing bowl, blend the softened cream cheese and sour cream (or Greek yogurt) until smooth. Stir in the garlic powder, onion powder, ranch seasoning, salt, and pepper. This mixture is the key to that velvety, tangy finish.
3. Add the Cheese, Bacon & Veggies
Stir in the shredded cheddar, Monterey Jack, and half of the grated Parmesan. Fold in most of the bacon and green onions, reserving some for garnish. Finally, add the cauliflower and gently mix everything to coat.
4. Assemble & Bake
Grease a casserole or 9×13-inch baking dish. Spread the cauliflower mixture evenly, then top with the remaining Parmesan. Bake at 375°F for 20–25 minutes, or until hot and bubbly with a golden top.
5. Garnish & Serve
Top with the reserved bacon bits and green onions. Serve it hot as a side or make it the main course by adding grilled chicken, ground beef, or crumbled sausage.
