Ingredients

Scale

1 large cauliflower head, cored and cut into small florets
1 1/2 cups shredded sharp cheddar cheese
4 oz cream cheese, softened
3/4 cup heavy cream
2 tbsp nutritional yeast
1 tsp garlic powder
1/2 tsp mustard powder
Salt and pepper, to taste

Instructions

Preheat oven to 375°F (190°C)
Toss cauliflower florets with olive oil, salt, and pepper. Roast for 20 minutes until tender but firm, not mushy
