Directions:
- Cook onions in water (enough to cover the onions) until tender; reserve 1/2 cup liquid from the onions, discard the remaining liquid.
- In a saucepan, melt 1/2 cup butter, whisk in flour, slowly add in the cream, and the reserved liquid from the onions; whisk until smooth and thick.
- Add in the cheddar and Parmesan cheeses, salt, pepper and the cayenne pepper; mix until the cheese are melted.
- Add in the onions, mix to combine.
- Transfer to a greased baking dish.
- In a small bowl, combine the breadcrumbs, melted butter and the 1-2 Tbsp grated Parmesan cheese; mix to combine.
- Sprinkle the breadcrumb mixture over the top of the casserole.
- Cover, and bake at 350 degrees for 40-45 minutes, uncover the last 20 minutes of baking to brown the top.
- Note: If desired, 2-3 cloves fresh minced garlic may be added to the melted butter before whisking in the flour.
