The Hot Brown sandwich from Louisville, Kentucky isn’t just another turkey leftover idea.
This open-faced masterpiece drowns thick-cut toast in creamy Mornay sauce, tops it with crispy bacon, and broils everything until golden and bubbling. One bite and you’ll understand why this 1926 Brown Hotel creation became a Southern comfort food legend.
I’ve spent weeks perfecting this recipe because the sauce makes or breaks the whole thing. Too thin and it runs off the bread. Too thick and it tastes like paste.
After burning through pounds of cheese and butter, I finally nailed the ratio that gives you restaurant-quality results at home.
What You’ll Need
For the Mornay Sauce
- 4 tablespoons unsalted butter
- 4 tablespoons all-purpose flour
- 2 cups whole milk (cold)
- 1½ cups shredded sharp cheddar cheese
- ½ cup grated Parmesan cheese
- ¼ teaspoon nutmeg
- ½ teaspoon garlic powder
- Salt and white pepper to taste
For the Hot Brown Sandwich Assembly
- 8 slices thick-cut white bread (Texas toast works best)
- 1½ pounds cooked turkey breast, sliced
- 8 strips bacon
- 2 large tomatoes, sliced
- Fresh parsley for garnish
- Paprika for garnish
Pro Tips
Start with cold milk when making the Mornay sauce. Hot milk creates instant lumps that no amount of whisking will smooth out. Cold milk gives the flour time to incorporate properly.
Don’t rush the roux. That butter and flour mixture needs a full 2 minutes of constant whisking. It should smell nutty but not brown. This step builds the foundation for a smooth, thick sauce.
Cook bacon to 75% doneness. Fully crispy bacon turns into charcoal under the broiler. Aim for chewy-crispy and let the broiler finish the job.
Mix sharp cheddar with Parmesan. Sharp cheddar alone tastes flat. The Parmesan adds salty depth that makes the sauce taste like it came from a professional kitchen.
Toast your bread before assembly. Untoasted bread soaks up sauce like a sponge and turns to mush. A quick toast creates a barrier that keeps everything crisp.

Substitutions and Variations
Turkey alternatives: Rotisserie chicken, leftover roasted chicken, or thick-cut deli turkey all work. I’ve made this with everything from Thanksgiving leftovers to grocery store rotisserie.
Bread swaps: Sourdough, French bread, or English muffins work if you’re out of white bread. Just pick something sturdy enough to hold sauce without dissolving.
Cheese options: Gruyère instead of cheddar gives it a fancier vibe. White cheddar works too. Keep the Parmesan for that nutty, salty punch.
Lighter version: Use 2% milk and reduce butter to 3 tablespoons. The sauce won’t be as rich but still tastes good.
Vegetable add-ins: Sautéed mushrooms or spinach work if you want extra veggies. Not traditional but tasty.
Breakfast twist: Swap turkey for ham and add a fried egg on top. Technically not a Hot Brown anymore, but really good.
Make Ahead Tips
The Mornay sauce can be made 2 days ahead. Store it in an airtight container in the fridge and reheat gently on the stove with a splash of milk to thin it out.
Cook the bacon ahead and refrigerate for up to 3 days.
Slice your turkey and tomatoes the night before. Just keep them covered so they don’t dry out.
How to Make the Hot Brown Sandwich
Step 1: Prepare the Mornay Sauce
Melt butter in a medium saucepan over medium heat. Once it’s bubbling, add the flour and whisk constantly for 2 minutes. You want a smooth paste that smells slightly nutty.
Slowly pour in the cold milk while whisking. Don’t dump it all at once. Keep whisking until the mixture thickens, about 5 minutes. It should coat the back of a spoon.
Remove from heat and stir in the cheddar and Parmesan until melted. Add nutmeg, garlic powder, salt, and white pepper. Taste and adjust seasoning.
Step 2: Cook the Bacon
Place bacon strips in a cold skillet and turn the heat to medium. Cook until they’re about 75% done, still a bit chewy but starting to crisp. Transfer to a paper towel-lined plate.
Step 3: Toast the Bread
Lightly toast your bread slices. You want them golden but not too crispy since they’ll go under the broiler later.
Step 4: Assemble Your Hot Brown Sandwich
Preheat your broiler to high and position the rack about 6 inches from the heat source.
Place two slices of toasted bread on each broiler-safe plate. Layer turkey slices generously over the bread.
Ladle the Mornay sauce over the turkey, making sure to cover everything. The sauce should be thick enough to cling but thin enough to drip down the sides.
Place 2 bacon slices in an X pattern over each sandwich. Add tomato slices on top.
Step 5: Broil Until Golden
Place the assembled Hot Brown sandwiches under the broiler for 3 to 5 minutes. Watch them closely because broilers are unpredictable.
You want the sauce bubbling and golden brown on top, with crispy edges on the bacon.
Step 6: Garnish and Serve
Sprinkle with paprika and fresh parsley. Serve immediately while everything is hot and bubbly.

Leftovers and Storage
Storage Reality Check: This Hot Brown sandwich is best eaten fresh. The sauce and crispy elements don’t reheat well once assembled.
Store leftover components separately. The Mornay sauce keeps in the fridge for up to 3 days in an airtight container. Reheat it gently on the stove with a splash of milk.
Cooked turkey lasts 3 to 4 days in the fridge. Bacon keeps for about a week.
To reheat, assemble a fresh Hot Brown sandwich with your prepped ingredients and broil as directed. Don’t microwave an already-assembled sandwich. You’ll end up with soggy bread and separated sauce.
Pairing Suggestions
The Hot Brown sandwich is rich and heavy, so pair it with something light and fresh.
A simple arugula salad with lemon vinaigrette cuts through the richness perfectly. Roasted asparagus or green beans work too.
For drinks, iced tea or a crisp white wine like Sauvignon Blanc balances the creamy sauce.
FAQ About Hot Brown Sandwiches
What makes a Hot Brown different from a regular turkey sandwich?
The open-faced presentation, the Mornay sauce, and the broiling step. A regular turkey sandwich is cold and portable. A Hot Brown is hot, messy, and requires utensils.
Can I make this Hot Brown sandwich without a broiler?
You can bake it at 400°F for about 10 minutes, but you won’t get the same golden, bubbly top. A broiler really makes the difference.
Why is it called a Hot Brown?
It was created at the Brown Hotel in Louisville, Kentucky in 1926 by chef Fred Schmidt. The “hot” part is because it’s served hot.
Can I use store-bought Alfredo sauce for my Hot Brown sandwich?
You could, but it won’t taste the same. Mornay sauce has Parmesan and nutmeg that give it a distinct flavor profile. Alfredo is close but not quite right.
Is this the same as turkey a la king?
No. Turkey a la king is turkey in a cream sauce served over rice or pasta. The Hot Brown is open-faced on toast with bacon and tomatoes, then broiled.
Do I have to use white bread for the Hot Brown sandwich?
No, but it’s traditional. White bread soaks up the sauce without overpowering the other flavors. Use what you like, just make sure it’s sturdy.
Can I freeze the Mornay sauce?
Technically yes, but cream sauces can separate when thawed. If you do freeze it, reheat it very slowly and whisk constantly to bring it back together.
What should I serve with a Hot Brown?
A simple green salad or roasted vegetables. The Hot Brown sandwich is rich and filling, so you want something light on the side.
Common Mistakes to Avoid
| Mistake | Why It’s a Problem | The Fix |
|---|---|---|
| Using hot milk | Creates instant lumps | Always use cold milk |
| Skipping the roux step | Thin, watery sauce | Whisk butter and flour for full 2 minutes |
| Overcooking bacon | Burns under broiler | Cook to 75% doneness only |
| Not toasting bread | Soggy, mushy sandwich | Toast bread before assembly |
| Walking away from broiler | Burnt top, undercooked middle | Watch constantly for 3-5 minutes |
Wrapping Up
The Hot Brown sandwich sounds fancy but it’s actually pretty straightforward once you’ve made the Mornay sauce a couple times.
It’s comfort food dressed up just enough to feel special, and it’s perfect for using up leftover turkey without eating the same boring sandwich three days in a row.
