The Hot Brown is a classic American open-faced sandwich that originated in Louisville, Kentucky. It's a comforting dish featuring layers of roasted turkey, fresh tomatoes, crispy bacon, and a rich, creamy Mornay sauce, all baked to perfection. This recipe is perfect for a hearty lunch or a satisfying dinner.
Most of the ingredients for this Hot Brown recipe are common household staples. However, you might need to ensure you have roasted turkey breast and parmesan cheese on hand. These items can be found in the deli and cheese sections of your supermarket, respectively. The rest of the ingredients, such as white bread, tomato, and bacon, are typically easy to find.

Ingredients For Hot Brown Recipe
White bread: Slices of soft, white bread form the base of the sandwich.
Roasted turkey breast: Sliced, cooked turkey breast adds a savory, meaty layer.
Tomato: Fresh tomato slices provide a juicy, acidic contrast.
Bacon: Crispy, cooked bacon adds a smoky, salty crunch.
Butter: Used to create the base of the Mornay sauce.
All-purpose flour: Combined with butter to thicken the sauce.
Milk: Warmed milk is used to create the creamy Mornay sauce.
Parmesan cheese: Grated cheese adds a rich, nutty flavor to the sauce.
Salt: Enhances the overall flavor of the dish.
Ground black pepper: Adds a touch of heat and depth to the sauce.
Technique Tip for This Recipe
When making the mornay sauce, ensure you whisk constantly while adding the warm milk to avoid lumps. This will result in a smooth and creamy sauce that coats the turkey and bread evenly. Additionally, make sure the parmesan cheese is finely grated so it melts quickly and integrates well into the sauce.

How to Store / Freeze This Dish
Allow the Hot Brown sandwiches to cool completely before storing. This helps prevent condensation, which can make the bread soggy.
Wrap each sandwich individually in plastic wrap or aluminum foil. This ensures that they stay fresh and prevents any flavors from mingling with other items in your fridge or freezer.
Place the wrapped sandwiches in an airtight container or a resealable plastic bag. This adds an extra layer of protection against freezer burn and helps maintain the quality of the turkey and mornay sauce.
Label the container or bag with the date. This helps you keep track of how long the sandwiches have been stored and ensures you consume them while they are still at their best.
Store the sandwiches in the refrigerator if you plan to eat them within 2-3 days. For longer storage, place them in the freezer where they can last up to 2 months.
To reheat, preheat your oven to 350°F (175°C). Remove the plastic wrap or aluminum foil and place the sandwiches on a baking sheet. Cover loosely with foil to prevent the bread from drying out.
Bake for 15-20 minutes if refrigerated, or 25-30 minutes if frozen, until the mornay sauce is bubbly and the turkey is heated through. For a crispier top, remove the foil during the last 5 minutes of baking.
Alternatively, you can reheat in a microwave. Place the sandwich on a microwave-safe plate and cover with a damp paper towel. Microwave on medium power for 2-3 minutes if refrigerated, or 4-6 minutes if frozen, checking halfway through to ensure even heating.
How to Reheat Leftovers
Preheat your oven to 350°F (175°C). Place the leftover Hot Brown on a baking sheet and cover it loosely with aluminum foil. Heat for about 15-20 minutes or until warmed through. This method helps maintain the crispiness of the bacon and the texture of the bread.
For a quicker option, use a microwave. Place the Hot Brown on a microwave-safe plate and cover it with a microwave-safe lid or another plate to prevent splattering. Heat on medium power for 1-2 minutes, checking halfway through to ensure even heating. Be cautious as the mornay sauce can get very hot.
If you have an air fryer, preheat it to 350°F (175°C). Place the Hot Brown inside and heat for about 5-7 minutes. This method will help keep the bacon crispy and the bread slightly toasted.
For stovetop reheating, use a non-stick skillet over medium-low heat. Place the Hot Brown in the skillet and cover with a lid. Heat for about 5-7 minutes, flipping halfway through to ensure even warming. This method can help maintain the texture of the bread and bacon.
If you prefer a toaster oven, preheat it to 350°F (175°C). Place the Hot Brown on a piece of aluminum foil or a baking tray and heat for about 10-15 minutes. This method is great for achieving a slightly crispy texture on the bread and bacon.
