Ingredients

  • 2 large Bermuda onions
  • 4 slices stale white bread (no crust)
  • 3/4 cup grated Cheddar cheese
  • 3/4 cup milk
  • 2 eggs
  • 3/4 teaspoon salt
  • 1/4 teaspoon pepper

Instructions

  1. Parboil the sliced Bermuda onions for 10 minutes.
  2. Layer the parboiled onions, cubed stale white bread, and grated Cheddar cheese in a buttered casserole dish.
  3. Combine milk, eggs, salt, and pepper; pour the mixture over the layered ingredients.
  4. Dot the top with small pieces of butter.
  5. Bake at 375°F (190°C) for 40 minutes until golden and bubbly.

Tips & Substitutions

For a twist, consider using Gruyère cheese instead of Cheddar for a richer flavor. If you're short on stale bread, toast fresh bread until golden brown. To enhance the dish, add cooked bacon or sautéed mushrooms between the layers. Be cautious not to overcook the onions during parboiling; they should remain slightly firm for better texture in the casserole.

Serving Suggestions

This Bermuda Casserole pairs beautifully with a crisp green salad or steamed vegetables for a complete meal. Consider serving it alongside roasted chicken or grilled fish for a hearty dinner. For a cozy breakfast option, enjoy it with fresh fruit or yogurt on the side, making it versatile for any time of day.

Storage & Reheating

Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, cover the casserole with foil to prevent drying out, and warm it in a preheated oven at 350°F (175°C) for about 20 minutes. Alternatively, microwave individual portions until heated through.
