Ingredient Notes

- Cauliflower: Fresh cauliflower should be bright and white without brown spots. Frozen cauliflower can also be used with increased roast time.
- Cream Cheese: Use softened block cream cheese so it blends easily into the warm cauliflower.
- Cheese: Other cheeses that would work are smoked cheddar, gouda, or mozzarella, so experiment and create a signature flavor.
- Bacon: Adds a delicious smoky flavor. Use pre-cooked bacon to make this easy.
- Green Onion: Chop small, then divide between the filling and topping. Chives are a great alternative.
How To Prep Cauliflower For Roasting
- Turn the cauliflower so that it is head side down on the cutting board.
- Cut the smaller stems from the large stem.
- Continue until all the florets are cut from the main stem and into bite-sized pieces.
