Preheat oven to 350F. Since I don’t have a steamer I improvised. Next time I am just going to boil the cauliflower, imo it doesn’t make a lot of difference. in this case I steamed the cauliflower for about 10 min.
Add butter to the skillet on medium high heat. Caramelize the onion in a bout 8 min. Add cumin, curry, mustard, and the chili peppers.
Add 1/3 cup shredded cheddar cheese and ½ tsp salt and the heavy cream.
Put the cauliflower in a baking dish. Pour the onion cheese mixture over the cauliflower. Add the remaining cheddar cheese in a bowl and add the breadcrumbs and chopped parsley. Sprinkle over the cauliflower. Wipe the sides down. Bake for 8 min till the sauce is bubbly. Put the oven on broil, broil for 4 min, the top should be slightly brown.
