How to Make the Hot Brown Sandwich
Don’t let the steps intimidate you — this classic hot brown recipe moves quickly once you get going. The sauce takes the most attention, so let’s start there.
Step 1: Make the Mornay Sauce
Melt the butter in a saucepan over medium heat. Once it’s foamy, whisk in the flour and keep stirring for a minute or two until it smells slightly nutty and turns a pale golden color.
Slowly pour in the milk, whisking constantly so no lumps form. Bring the mixture to a boil, still stirring — this is your moment to really commit to the whisk.
“The secret to a lump-free sauce is patience. Add the milk gradually and keep that whisk moving the whole time.”
Once thick and bubbly, stir in the Parmesan cheese. Then add the beaten egg quickly while stirring — it thickens the sauce beautifully. Remove from heat and stir in the heavy cream.
Step 2: Preheat Your Broiler
While the sauce rests, preheat your oven’s broiler on high. Position the rack about 6 inches from the heat. You want it hot and ready so the tops go beautifully speckled and golden.
This is also a good moment to get your individual casserole dishes ready. Four oven-safe dishes work best for this cheesy turkey sandwich experience.
Step 3: Build the Sandwiches
For each hot brown sandwich, place two slices of toasted bread into the bottom of a casserole dish. Don’t overlap — lay them flat so every bite has that crispy base.
Pile on a generous amount of roasted turkey. Don’t be shy here — this is a Kentucky Hot Brown, not a light snack. Layer the tomato slices on top and season everything with salt and pepper.
Now comes the fun part: spoon that warm, creamy sauce generously over each sandwich. Then sprinkle with a little more Parmesan. More is more, always.
Step 4: Broil Until Golden
Slide the dishes under the broiler and watch closely. After about 5 minutes, the tops should be spotted brown and gloriously bubbly.
Pull them out and immediately lay two strips of crispy bacon in a cross shape on top. That’s the signature move for an authentic Classic Hot Brown Recipe — and it looks stunning.
Expert Tips for the Best Results
Use Good Roasted Turkey
Leftover roasted turkey from a holiday meal is absolutely perfect here. Deli turkey works fine too, but go for thick-sliced so it doesn’t dry out under the broiler.

Don’t Walk Away from the Broiler
Broilers are sneaky. Things go from golden to burnt in about thirty seconds flat. Stay close and keep an eye on the dishes the entire time.
Make the Bacon Extra Crispy
Floppy bacon on a hot brown is a tragedy. Cook yours until it’s genuinely crispy so it holds its shape in that classic cross pattern on top.
Whisk the Sauce Like You Mean It
Lumpy sauce is the only real risk in this recipe. Keep whisking consistently when adding the milk and you’ll have a silky, smooth Mornay every time.
Variations to Try
Swap the Protein
No turkey? Thinly sliced roasted chicken works beautifully in this cheesy turkey sandwich. Some people even use pulled pork for a smoky Southern twist.
Add Some Heat
Stir a pinch of cayenne pepper or a dash of hot sauce into the Mornay sauce. It wakes up the whole dish and adds a subtle kick that pairs wonderfully with the rich cheese sauce.
Try Different Bread
White sandwich bread is traditional, but thick-cut sourdough or brioche toast takes this hot brown sandwich to a whole new level of indulgence.
Go Vegetarian
Roasted portobello mushrooms and thick slices of tomato make a surprisingly satisfying meatless version. The sauce is so rich that you honestly don’t miss the turkey much.
Troubleshooting Common Issues
Sauce Too Thin?
Let it cook a bit longer before adding the egg. The roux needs to be properly cooked and the milk fully incorporated to give the sauce enough body. Adding the beaten egg also helps thicken it up.
Bread Getting Soggy?
Toast your bread until it’s genuinely golden and firm — not just lightly colored. A sturdier toast holds up much better under that glorious sauce.
Cheese Not Browning?
Make sure your broiler is fully preheated before the dishes go in. A cold broiler gives you steamed rather than broiled results, and nobody wants that.
Storage and Reheating Guide
| Method | Duration | Notes |
|---|---|---|
| Refrigerator (assembled) | Up to 2 days | Store without bacon on top |
| Sauce only (fridge) | Up to 4 days | Reheat gently, add splash of milk |
| Freezer (sauce only) | Up to 2 months | Thaw overnight in fridge |
| Reheat in oven | 10 mins at 350F | Cover with foil to prevent drying |
| Reheat under broiler | 2-3 minutes | Watch closely, add fresh bacon |
Got leftover sauce? It doubles as an incredible dip for roasted vegetables or drizzled over baked potatoes. No-waste kitchen wins are the best wins.

Frequently Asked Questions
What is a hot brown sandwich exactly?
A hot brown sandwich is an open-faced Kentucky classic invented at the Brown Hotel in Louisville in 1926. It’s built on toast, layered with roasted turkey and tomato, then smothered in a Mornay cheese sauce and broiled until bubbly. Bacon on top is non-negotiable.
Can I make the sauce ahead of time?
Absolutely. The Mornay sauce keeps well in the fridge for up to four days. When you’re ready to use it, reheat gently over low heat with a small splash of milk, stirring until smooth. It’ll be just as good as fresh.
What’s the difference between a hot brown and a regular open-faced sandwich?
The Kentucky Hot Brown is defined by its signature Mornay sauce — that rich, Parmesan-laced cream sauce sets it apart from any ordinary open-faced sandwich. The broiling step and the crossed bacon on top are also part of what makes it iconic and unique.
Can I use leftover Thanksgiving turkey?
That’s honestly one of the best uses for leftover holiday turkey. The slightly richer flavor of oven-roasted turkey makes this Classic Hot Brown Recipe taste even more incredible. It’s the ultimate post-Thanksgiving comfort meal.
What should I serve alongside this cheesy turkey sandwich?
A simple green salad with a light vinaigrette balances the richness perfectly. For something sweet afterward, this no-bake banana pudding cups recipe is a total crowd-pleaser that requires zero oven time. Or cool things down with a scoop of nectarine frozen yogurt for a refreshing finish.
