Ingredients

  • 1/4 cup chopped yellow onions
  • 6 tablespoons unsalted butter
  • 2 tablespoons flour
  • 1/2 cup water
  • 2 cups shredded Cheddar cheese
  • 1 head cauliflower, chopped and blanched
  • 3 well-beaten eggs
  • 2 tablespoons chopped fresh parsley
  • 1/2 cup buttered, toasted bread crumbs

Instructions

  1. Saute chopped yellow onions in 4 tablespoons of butter until soft.
  2. Add flour and water to the onions to make a white sauce.
  3. Blend in the blanched cauliflower and shredded Cheddar cheese.
  4. Add the well-beaten eggs and mix until blended.
  5. Pour the mixture into a greased 1 1/2-quart casserole dish.
  6. Cover the casserole with toasted bread crumbs, chopped parsley, and 2 tablespoons of melted butter.
  7. Bake at 350°F for 30 minutes until golden and bubbly.

Tips & Substitutions

For a creamier texture, consider adding a splash of milk or cream to the white sauce while cooking. If you're short on Cheddar cheese, a mix of Gruyère and mozzarella can add depth. Fresh herbs like thyme or chives can elevate the dish beyond its core flavors. Ensure the cauliflower is well-blanched to maintain its texture during baking.

Serving Suggestions

This dish pairs beautifully with a fresh side salad or roasted vegetables for a complete meal. Consider serving it alongside grilled chicken or a hearty soup to round out the flavors. For a vegetarian option, it complements a light quinoa salad or a platter of roasted seasonal veggies. Perfect for a cozy family dinner or holiday gatherings.

Storage & Reheating

Store any leftover Golden Cauliflower Au Gratin in an airtight container in the refrigerator for up to 3 days. To reheat, place it in a preheated oven at 350°F for about 15-20 minutes, or until heated through. If you prefer the topping to stay crispy, cover it loosely with foil to prevent burning.
