Kentucky Derby Hot Brown Sliders (Printable)

Savory sliders with turkey, bacon, Mornay sauce, and toasted brioche buns—ideal for festive gatherings.

# Components:

→ For the Sliders

01 - 12 mini brioche slider buns, sliced
02 - 12 slices roasted turkey breast, approximately 14 oz total
03 - 6 slices thick-cut bacon, cooked and halved
04 - 2 Roma tomatoes, thinly sliced
05 - 1 tablespoon unsalted butter for toasting buns

→ For the Mornay Sauce

06 - 2 tablespoons unsalted butter
07 - 2 tablespoons all-purpose flour
08 - 1 cup whole milk
09 - 1/2 cup heavy cream
10 - 1 cup grated sharp white cheddar cheese
11 - 1/4 cup grated Parmesan cheese
12 - 1/4 teaspoon ground nutmeg
13 - 1/2 teaspoon salt
14 - 1/4 teaspoon black pepper

→ Garnish

15 - 2 tablespoons chopped fresh parsley
16 - 1/4 teaspoon smoked paprika, optional

# Method:

01 - In a medium saucepan over medium heat, melt 2 tablespoons butter. Whisk in the flour and cook for 1-2 minutes until bubbling but not browned. Slowly add the milk and cream while whisking constantly to prevent lumps. Cook until thickened, approximately 3-4 minutes.
02 - Remove from heat and stir in cheddar cheese, Parmesan cheese, nutmeg, salt, and pepper. Whisk until smooth and keep warm.
03 - In a large skillet, melt 1 tablespoon butter over medium heat. Place the cut sides of the brioche slider buns face-down and toast until golden brown, approximately 1-2 minutes.
04 - Place the bottom halves of the toasted buns on a baking sheet. Layer each with one slice of turkey, one tomato slice, and 1 tablespoon of Mornay sauce. Top with half a bacon slice.
05 - Preheat the broiler. Slide the assembled bottoms without tops under the broiler for 2-3 minutes until the sauce is bubbly and lightly golden.
06 - Remove from the oven and sprinkle with fresh parsley and smoked paprika if desired. Top each slider with the brioche bun top half.
07 - Serve immediately while warm.

# Expert Advice:

01 -
  • They taste like a fancy restaurant appetizer but come together faster than you'd think, especially if you've already roasted a turkey.
  • The Mornay sauce is smooth, cheesy, and rich enough to feel indulgent while the brioche buns stay pillowy instead of soggy.
  • These actually work as elegant finger food that doesn't leave your guests with greasy hands, which is secretly why people prefer them to the full-size version.
02 -
  • The Mornay sauce is your whole recipe—get it right and the sliders are effortless, get it wrong and you'll end up with either a thin puddle or a broken curdled mess, so don't rush the whisking part.
  • Assembling these ahead of time and then broiling them actually works better than I expected because the cold filling heats through gently instead of the outside overcooking before the inside warms.
03 -
  • Keep your Mornay sauce warm in a double boiler or just a bowl set over a pot of simmering water so it doesn't break or separate while you're assembling.
  • If you're making these for a crowd, prep your brioche buns first so they cool slightly and won't steam the filling—you want that structural integrity.
