- Layer bread cubes in a 1 1/2-quart casserole pan.

- Beat eggs in a bowl.
- Add pepper and milk to the eggs and mix well.

Tips & Substitutions
For a richer flavor, consider using caramelized onions instead of sautéed ones. If you want a vegetarian twist, substitute the Parmesan with a dairy-free cheese. Stale bread works best for this recipe, as it absorbs the egg mixture better. You can also add herbs like thyme or rosemary for extra depth.
Serving Suggestions
This dish pairs beautifully with a fresh salad or roasted vegetables for a complete meal. Consider serving it alongside Apple Walnut Crisp for dessert or a hearty soup for a cozy dinner. It makes for a comforting brunch option as well, especially with a side of fruit.

Leftover Thanksgiving Onion Pie can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, place slices in a preheated oven at 350°F for about 15–20 minutes or until warmed through. Avoid microwaving, as it can make the texture soggy.
