Let’s take a look at how this delicious cauliflower bake is made with simple ingredients.
Ingredients
This dish is made with a lot of basic ingredients that you should be able to find at all grocery stores.
- 2 heads fresh cauliflower
- 3 ½ cups shredded Cheddar cheese
- 6 ounces cream cheese
- ½ cup sour cream
- ½ teaspoon onion powder
- ½ teaspoon garlic powder
- 8 slices crispy bacon
- salt
- black pepper
- green onions (optional)

Directions
- Preheat your oven to 425° Fahrenheit. Spray a 9×13-inch baking dish with non-stick spray. Set the pan aside and get ready to cook!
- Cut the heads of cauliflower into florets that are bite-sized. You’re not going to use the stems in this recipe, so you can toss them into your compost pile. Place the cauliflower florets in a pot, fill it with 1 to 2 inches of water, cover, and steam for 5-7 minutes. The steamed cauliflower should be tender but still have a crunch. Drain the cooked cauliflower.

- Combine sour cream, cream cheese, 3 cups Cheddar cheese, onion powder, and garlic powder in a large mixing bowl.




- Fold in the cauliflower and chopped bacon (from the 6 slices).

- Pour the cauliflower-cream cheese mixture into the prepared baking dish and bake in the preheated oven on the center rack for 25-30 minutes, uncovered.

- Remove the casserole from the oven and sprinkle the remaining cheese and chopped bacon over it. Bake for an additional 5 minutes.

- Remove from oven and let cool for 5-10 minutes before serving. Sprinkle with chopped green onions, if desired.

Tips For Steaming Cauliflower
If you have a steamer basket, use it. Otherwise, place the cauliflower in a pot, add 2 inches of water, cover, and steam/cook over medium-high heat for 5-7 minutes.
Alternatively, you can microwave the cauliflower with 2-3 tablespoons of water in a glass bowl, covered with a plate, for 3 – 4 minutes. (You can learn more about how to microwave steam cauliflower at Baking Mischief.)
