Classic Louisville Hot Brown Recipe Easy Homemade Open-Face Turkey Sandwich Guide

That’s how the Classic Louisville Hot Brown Open-Face Turkey Sandwich entered my kitchen—and honestly, it changed my sandwich game forever. The menu was from the Brown Hotel in Louisville, Kentucky, dated back to the 1950s, and there it was: the Hot Brown, described as a “delicious open-faced sandwich with turkey, bacon, tomato, and a creamy Mornay sauce.”

That rainy day turned into a cooking adventure as I tried to recreate that rich, creamy, slightly crispy masterpiece at home. I made a mess on the counter (of course), forgot to crisp the bacon once, and nearly burned the sauce the first time. But the way the turkey mingled with the gooey cheese sauce and the hint of tomato sweetness hooked me instantly. Maybe you’ve been there—trying to replicate something special you stumbled upon unexpectedly and ending up with a new favorite.

What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without any fuss. Most are easy to find in your local grocery store, and a few pantry staples pull it all together beautifully.

• For the Sandwich Base:
  • Thick slices of white bread or Texas toast (sturdy enough to hold the toppings without sogging)
  • Cooked turkey breast, sliced or shredded (leftover roast turkey works great)
  • Ripe tomatoes, thinly sliced (adds freshness and a slight tang)
  • Bacon strips, cooked until crisp (for that smoky crunch)
• For the Mornay Sauce:
  • Unsalted butter (adds richness and helps with the roux)
  • All-purpose flour (for thickening the sauce; can swap with gluten-free flour if needed)
  • Whole milk, warmed (for creaminess; dairy-free milk can be used but flavor will vary)
  • Grated sharp white cheddar cheese (I prefer Cabot for its sharpness)
  • Grated Parmesan cheese (adds depth and umami)
  • Salt and freshly ground black pepper (to taste)
  • A pinch of freshly grated nutmeg (classic in Mornay sauce, but optional)

Tip: When selecting turkey, look for moist breast meat rather than dry deli slices. If you want to keep things simple, leftover Thanksgiving turkey is perfect here. And if you want to make this gluten-free, just swap the bread and flour accordingly.

Equipment Needed

• Medium saucepan (for making the Mornay sauce)
• Whisk (to keep the sauce smooth and lump-free)
• Baking sheet or oven-safe dish (for broiling the assembled sandwiches)
• Cooking tongs (handy for flipping bacon and handling turkey slices)
• Sharp knife and cutting board (for slicing tomatoes and bread)
• Optional: cheese grater (if you’re using block cheese instead of pre-grated)

If you don’t have a whisk, a fork works in a pinch, though you might get a few lumps. For crisping bacon, a cast iron skillet adds great flavor, but a regular non-stick pan is just fine. I find a rimmed baking sheet makes cleanup easier, especially when broiling the sandwiches to bubbly perfection.

Preparation Method

1. Preheat your oven’s broiler. Set an oven rack about 6 inches from the heat source. This is where you’ll finish the sandwiches for that golden, bubbly top.
2. Prepare the Mornay sauce. Melt 3 tablespoons (45g) of unsalted butter in a medium saucepan over medium heat. Once melted, whisk in 3 tablespoons (24g) of all-purpose flour and cook for about 1-2 minutes, stirring constantly to form a smooth roux (it should look pale and bubbly but not browned).
3. Slowly add 2 cups (480ml) of warm whole milk. Whisk continuously to avoid lumps. Keep cooking and whisking until the sauce thickens and coats the back of a spoon—this usually takes about 5-7 minutes.
4. Remove the pan from heat. Stir in 1 cup (100g) grated sharp white cheddar and ½ cup (45g) grated Parmesan cheese until melted and smooth. Season with salt, freshly ground black pepper, and a pinch of freshly grated nutmeg. Taste and adjust seasoning as needed.
5. Toast the bread slices. Lightly toast 4 thick slices of white bread or Texas toast until just golden but still firm.
6. Assemble the sandwiches on a baking sheet. Place the toasted bread slices on the sheet. Layer each with a generous portion of sliced turkey, then arrange tomato slices on top.
7. Pour the warm Mornay sauce over each sandwich. Make sure to cover the turkey and tomatoes well, but don’t drown the bread.
8. Top each sandwich with 2-3 crispy bacon strips. This adds that essential smoky crunch.
9. Broil the sandwiches for 3-5 minutes. Watch closely until the sauce is bubbly and lightly browned on top. The kitchen will smell heavenly—don’t get distracted!
10. Remove from the oven and let cool for a minute. Serve warm and enjoy that creamy, crunchy, savory magic.

Note: If your sauce thickens too much before pouring, gently rewarm it over low heat with a splash of milk to loosen it up. Also, keep a close eye during broiling; the sauce can go from perfect to burnt rapidly.

Cooking Tips & Techniques

Making a Classic Louisville Hot Brown sandwich at home can feel intimidating, but with a few insider tips, you’ll nail it every time. First off, the key to a smooth Mornay sauce is patience and constant whisking—don’t rush it or you’ll get lumps. If lumps appear, strain the sauce or whisk vigorously off heat.

I’ve learned the hard way that crisp bacon adds essential texture contrast; soft bacon just doesn’t cut it here. Cook your bacon ahead of time on medium heat to avoid burning and keep it crispy but pliable enough to layer.

Another tip: Use fresh, thick bread slices that can hold up to the sauce without becoming soggy. Toasting the bread slightly makes a big difference. If you’re short on time, broil the assembled sandwich right after assembly, but if you have a minute, let the sauce sit on the turkey and bread for a couple of minutes before broiling to meld the flavors.

Timing is everything when broiling. Stay close and watch for bubbling and slight browning. If you’re multitasking, set a timer to avoid that burnt finish. Lastly, don’t skip the nutmeg in the sauce—it adds a subtle warmth that makes this sandwich special.

Variations & Adaptations

This recipe is pretty classic, but there’s room to make it your own. Here are a few ideas I’ve tried or recommend:

• Vegetarian Version: Swap turkey and bacon with sautéed mushrooms and smoked paprika for that umami punch. Use a vegetarian cheese sauce (skip Parmesan if strict vegetarian).
• Spicy Kick: Add a dash of cayenne pepper or hot sauce to the Mornay sauce for a subtle heat that wakes up the flavors.
• Gluten-Free: Use gluten-free bread and substitute the flour in the sauce with a gluten-free blend or cornstarch (use half the amount).
• Seasonal Twist: In summer, try fresh heirloom tomatoes and basil on top instead of regular tomatoes. It brightens the whole sandwich beautifully.
• Swap Cheeses: I’ve played with Gruyère instead of cheddar for a nuttier flavor, or added a bit of blue cheese for a punchy surprise.

One variation I keep coming back to is adding caramelized onions under the turkey—adds a sweet counterpoint that balances the richness perfectly.

Serving & Storage Suggestions

The Classic Louisville Hot Brown is best served warm right out of the oven when the Mornay sauce is still creamy and the bacon crispy. Pair it with a simple side salad dressed in a tangy vinaigrette to cut through the richness. For a brunch spread, it goes well with fresh fruit and a mimosa or iced tea.

Leftovers can be refrigerated in an airtight container for up to 2 days. To reheat, cover loosely with foil and warm in a 350°F (175°C) oven until heated through—this helps avoid soggy bread. Microwave reheating tends to make the bread gummy, so I don’t recommend it unless you’re in a hurry.

Interestingly, the flavors deepen if you make the sauce a little ahead and let the sandwich sit for 20 minutes before broiling, but don’t wait too long or the bread will lose its crunch.

Nutritional Information & Benefits

This Classic Louisville Hot Brown sandwich packs protein from turkey and bacon, calcium from the cheese-rich Mornay sauce, and some vitamins from the fresh tomato slices. One serving (1 sandwich) roughly contains:
