Grab your knife and fork for this supremely satisfying, over-the-top Kentucky Hot Brown Sandwich! It is served open-faced with thick slices of roasted turkey, crispy bacon, and fresh tomatoes on top of a thick piece of toasted bread, all smothered in a rich, cheesy mornay sauce.
We love substantial sandwiches for dinner and this is one of our new favorites! Some other sandwich recipes that we love are Monte Cristo Sandwiches, Pulled Pork Sandwiches, Kneader’s Copycat Turkey Bacon Avocado Sandwich, and Grilled Caprese Panini.
It’s Kentucky Week on House of Nash Eats! I love exploring the flavors of the USA, and have been making some of the most popular dishes from each state at home in my own kitchen. I call it my “American Eats” series, and it has turned into a fun tradition that we enjoy as a family.
What is a hot brown?
A hot brown is a Kentucky original, created in 1926 at the Brown Hotel in Louisville. It was invented to serve to hungry hotel guests who came for the dancing that occurred at the hotel every night. It’s referred to as a “sandwich” but really it’s so much more.
The sandwich is served hot, with a thick piece of white bread as the base. Some people like to use Texas toast, although any thick, good quality white bread will do. This is followed by layers of thickly sliced roasted turkey. You can use turkey leftovers, if you happen to have them on hand, or do what I did and ask for the thickest slices of roast turkey that you can get at the deli counter.
Then you top the turkey with thick-sliced tomatoes and smother the whole thing with a creamy, homemade mornay sauce. Don’t be intimidated by the fancy name.
Mornay is just a simple sauce that starts with a butter and flour roux. Then you add some milk, salt and pepper, before melting in some cheese. Freshly grated Parmigiano-Reggiano and Gruyere go into my favorite version of mornay sauce, but white cheddar can be used instead if you prefer. Finish off the sauce with a pinch of nutmeg and a dash of hot sauce, to taste.
The whole thing is sprinkled with a little more cheese, then broiled until toasty warm and delicious. The finishing touch is to top each sandwich with two slices of crispy bacon and a sprinkle of chopped parsley and paprika.
How to make a hot brown sandwich
- Start with the mornay sauce. Heat the milk first in the microwave so it’s warm when you are ready to add it to the roux.
- Make the roux. Melt some butter in a large pan over medium heat. Whisk in the flour and cook for 1 minute.
- Add the heated milk, then thicken. Gradually whisk in the hot milk and bring to a boil. Cook until it starts to simmer and is thickened, whisking almost constantly, about 3-5 minutes. Remove from the heat and whisk in cheese until melted. Season with nutmeg, salt, and pepper, to taste.
- Roast the tomatoes. Arrange tomato slices on a baking sheet and drizzle with a little oil and sprinkle with salt and pepper. Broil for 1-2 minutes per side until lightly charred.
- Toast the bread. Butter bread slices and place on foil-lined baking sheets. Toast under the broiler for 1-2 minutes, then flip and toast the other side.
- Assemble the sandwiches and cook under the oven broiler. Top toasted bread with the turkey, then tomato, then the mornay sauce, then sprinkle with additional cheese and broil for 2-3 minutes. Transfer to plates and top with bacon. Sprinkle with parsley or chives before serving.
