Step 1

Preheat oven to 375˚F. Melt butter in a skillet over medium heat and add onions to pan. Cook for 5 minutes then add broth, spices, and Worcestershire sauce and stir well. Cook for 5 more minutes, then reduce heat to simmer and cook for 10 minutes more. Remove from heat and allow to cool for 10 minutes.

Step 2

Whisk sour cream into onions then stir in half the cheese. Place cauliflower into a greased 9”x13” baking dish and add salt and pepper to taste. Pour sauce over top. Sprinkle remaining cheese on top.

Step 3

Bake for 30 minutes or until cheese is beginning to brown around the edges. If top browns too early cover with foil part way through cooking.
