Ingredient Highlights & Substitutions
Essential Ingredients
Day-old bread (French bread, sourdough, or sandwich bread) is the base. Diced cooked ham provides the protein. Cheddar or Swiss cheese adds the melt factor. Eggs and milk create the custard. A little dry mustard and onion powder season the dish subtly but effectively.
Smart Substitutions
If you want to make it vegetarian, use sautéed spinach, mushrooms, and peppers instead of ham. You can use gluten-free bread if needed (just make sure it’s toasted first so it doesn’t disintegrate). Almond milk can replace dairy milk, though the custard will be slightly less rich.
Step-by-Step Instructions
Prep Phase
Grease a 9×13 inch baking dish. Cube the bread and dice the ham. Grate the cheese. Whisk the eggs, milk, and spices in a large bowl.
Cooking Phase
Scatter half of the bread cubes in the dish. Top with half the ham and half the cheese. Repeat the layers. Pour the egg mixture evenly over the casserole, pressing down with a spatula to ensure all the bread gets soaked. Cover tightly with foil and refrigerate overnight (or at least 4 hours). In the morning, preheat the oven to 350°F (175°C). Bake covered for 20 minutes, then uncover and bake for another 30-40 minutes until golden and set.
Pro Tips for Perfect Results
Technique Secrets
The “press down” is vital. Dry bread on top will burn. Make sure every cube has met the egg mixture. Also, let the casserole sit on the counter for 20 minutes before putting it in the oven to take the chill off; this helps it cook evenly.
Common Mistakes to Avoid
Don’t use super fresh soft bread; it can turn to mush. If your bread is fresh, toast the cubes in the oven for 10 minutes to dry them out first.
Serving Ideas & Pairings
Presentation & Plating
Cut into squares and serve hot. A garnish of fresh parsley or fruit on the side makes it look elegant.
Pairing Suggestions
Serve with a light fruit salad and a mimosa or fresh juice for the full brunch experience.
