Ingredients
- 8 slices white bread (crusts removed)
- 8 slices American cheese
- 1 can chunk tuna (drained)
- ½ tbsp prepared mustard
- salt (to taste)
- pepper (to taste)
- mayonnaise (enough to bind tuna mixture)
- 4 eggs (large, beaten)
- 3 cups milk
- ½ tsp salt
- ¼ tsp black pepper
- 1 can condensed mushroom soup (optional)
- 1 tsp dry mustard
- ½ cup milk (for optional sauce)
- ½ cup pimientos (optional)
- 2 eggs (hard-boiled, optional, chopped)
- 1 can mushroom pieces (optional)
Instructions
Step 1: Prepare the Bread Base
- Remove crusts from the bread.
- Butter one side of each slice.
Step 2: Assemble Tuna-Cheese Layers
- Spread tuna mixed with prepared mustard, mayonnaise, salt, and pepper onto four slices of bread.
- Top each with one slice of American cheese.
- Cover with the remaining four slices of bread to form sandwiches.
Step 3: Arrange in Baking Dish
- Place sandwiches in a greased 9×14-inch baking pan.
Step 4: Prepare the Custard
- In a bowl, whisk together eggs, milk, ½ tsp salt, ¼ tsp pepper, and dry mustard (if using).
Step 5: Pour and Soak
- Pour the custard mixture evenly over the sandwiches.
- Cover and refrigerate overnight to allow the bread to absorb the custard.
Step 6: Bake the Cheese Puff
- Preheat oven to 300°F (150°C).
- Bake uncovered for 1 hour, or until golden and set in the center.
Step 7: Optional Mushroom Sauce
- In a saucepan, combine condensed mushroom soup, ½ cup milk, pimientos, hard-boiled eggs, and mushroom pieces.
- Heat until warmed through and serve over the baked Cheese Puff if desired.
Tips
- Use day-old bread to better absorb the custard mixture
- Substitute ham or bacon for tuna if preferred
- Add pimentos or mushrooms as suggested on the card for extra flavor
- Make the optional sauce with cream of mushroom soup + milk for a richer dish
- Use sharp cheddar instead of American cheese for stronger flavor
- Add dry mustard to the custard (noted with a question mark on card) for tang
- Ideal for overnight prep, assemble the day before and bake in the morning
- Reduce milk slightly for a firmer, more bread-pudding-like texture
- Serve as brunch, breakfast, or light dinner
- Leftovers reheat well and freeze successfully in portions
