Hot Brown Burgers: A Decadent Twist on a Kentucky Classic
Melted cheese sauce, smoky bacon, and ripe tomato come together for a crave-worthy meal.

Hot Brown Burgers are a mouthwatering tribute to Louisville’s famous Hot Brown sandwich. They blend the juiciness of a classic burger with the rich flavors of roasted turkey, smoky bacon, and a velvety cheese sauce. This recipe reimagines Southern comfort, stacking layers of indulgence on a toasted bun for a meal that’s as hearty as it is unforgettable.
What Is a Hot Brown?
The Hot Brown sandwich was first served at the Brown Hotel in Louisville, Kentucky, during the 1920s. Traditionally, it features roast turkey piled onto toast, slathered in a creamy Mornay sauce, and broiled until bubbling and golden, then topped with crispy bacon and juicy tomato slices. This luxurious open-faced sensation quickly became a Derby-week legend and a favorite throughout bluegrass country.
The Inspiration: Burger Meets Icon
Savory beef patties and Buns stand in for bread. Turkey is swapped for ground beef, with all the original’s signature toppings—Mornay sauce, tomato, crisp bacon—retained for a truly decadent interpretation. The burger format makes this Kentucky classic accessible at any gathering, from backyard cookouts to casual dinner parties.
Key Ingredients for Authentic Flavor
- Ground Beef: Choose high-quality ground chuck with 20% fat for juicy, flavorful patties.
- Mornay Sauce: A smooth cheese sauce made from butter, flour, milk, and shredded Gruyère (or sharp cheddar), plus Parmesan for extra depth.
- Thick-cut Bacon: Smoky, crispy strips add crunch and a savory backbone.
- Fresh Tomato Slices: Acidity balances the richness of the cheese and beef.
- Buns: Choose substantial, bakery-style buns sturdy enough for saucy toppings.
- Butter: For toasting buns and enriching the sauce.
- Seasonings: Nutmeg, salt, pepper, and hot sauce for complexity.
Hot Brown Burger: Step-by-Step Recipe
Ingredients
Ingredient | Quantity | Notes |
---|---|---|
Ground beef (80/20) | 1 1/2 lbs | Form into 4-6 patties |
Thick-cut bacon | 8 slices | Cooked until crispy |
Tomato | 1 large | Sliced crosswise |
Gruyère cheese | 1 cup, shredded | For Mornay sauce |
Parmesan cheese | 1/4 cup, grated | For Mornay sauce |
Butter | 2 tbsp | For sauce and buns |
Flour | 2 tbsp | Mornay thickener |
Milk | 1 1/2 cups | Whole is best |
Salt & pepper | To taste | Season everything |
Ground nutmeg | Pinch | Optional |
Hot sauce | To taste | Cayenne, Tabasco… |
Bakery-style buns | 4-6 | Split and toasted |
Instructions
- Cook the Bacon: Pan-fry bacon over medium heat until shatteringly crisp. Drain on paper towels.
- Make the Mornay Sauce:
- In a saucepan, melt butter over medium heat. Whisk in flour and cook, stirring constantly, until pale golden (about 1 minute).
- Slowly whisk in milk, ensuring no lumps form. Simmer, stirring, until thickened (2–3 minutes).
- Remove from heat; stir in shredded Gruyère, Parmesan, a pinch of nutmeg, and hot sauce for zip. Season to taste with salt and pepper.
- Toast the Buns: Brush cut sides of buns with melted butter; toast in a hot skillet or under a broiler until golden and crisp.
- Shape and Cook Burger Patties: Form beef into equal-sized balls (loosely packed for tender texture). Season generously.
- Heat skillet, griddle, or grill to high. Sear patties for 2–3 minutes per side, until browned and medium-rare to medium (160°F internal temp).
- Stack the Burgers:
- Place patty on bun base. Spoon warm Mornay sauce generously over top.
- Add one or two crispy bacon strips and a juicy tomato slice.
- Finish with top bun (optional; true Hot Browns are open-faced).
Pro Tips for the Perfect Hot Brown Burger
- Do Not Overwork the Beef: Gently form the patties—handling too much compacts them.
- Mornay Must Be Smooth: Whisk thoroughly. If the sauce seems too thick, thin with extra splash of milk.
- Cheese Choices: For added Southern flavor, swap Gruyère for sharp white cheddar or smoked gouda.
- Broiling for a Browned Top: For an authentic finish, broil the assembled burgers briefly to bubble and brown the sauce.
- Tomato Selection: Use ripe, summer tomatoes for maximum taste.
Variations and Substitutions
- Ground Turkey
- For a lighter spin, use lean ground turkey or chicken in place of beef.
- Vegetarian Version
- Swap beef for grilled portobello mushrooms or a plant-based patty. Substitute vegetarian bacon for garnish.
- Louisville Twist
- Add a dash of bourbon to the Mornay sauce for a local flair.
- Southern Add-ons
- Top with sautéed mushrooms, or sprinkle with fresh chives.
Serving Suggestions
- Pair With: Creamy coleslaw, sweet potato fries, or a simple green salad.
- Drink Matches: Kentucky bourbon, classic pilsner, or sweet iced tea.

A: Classic Hot Brown uses Gruyère and Parmesan, but sharp white cheddar or smoked gouda can add Southern flair.

A: Choose beef with 20% fat, avoid pressing patties while cooking, and don’t overmix the meat.
Q: Are Hot Brown burgers always open-faced?
A: Traditionally, yes! But feel free to top with the other half of the bun for ease of handling if you prefer.
Q: Can the recipe be doubled for a crowd?
