Ingredients
- 2 bags riced cauliflower
- 2 Tablespoons grated Parmesan cheese
- 1 Tablespoon scallions (plus more for garnish)
- 3 Tablespoons butter
- 1 Tablespoon onion
- 1 Tablespoon minced garlic
- 1 cup vegetable broth
- 1 cup milk (this recipe used 2%)
- 2 Tablespoons prepared horseradish

- ½ teaspoon black pepper
- ½ cup shredded sharp or extra sharp cheddar cheese
- Melt butter in large skillet over low heat. Add onion, garlic, and cauliflower, cooking and stirring until tender but not brown, 3-5 minutes. Pour in broth and bring to a boil. Cook over high heat until broth evaporates completely, 8-10 minutes. Remove from heat.
- Pour milk into skillet; transfer to blender and purée (or purée with an immersion blender) until smooth. Stir in horseradish, Parmesan, salt, and pepper. Transfer to a 9-inch baking dish (I used an 11-in x 7-in pan) . Top with cheddar cheese.
- Bake uncovered until golden brown, about 25 minutes. Garnish with scallions (if using).
