Kentucky Derby Hot Brown Sliders (Printable Version)

Mini brioche sliders layered with turkey, bacon, tomato, and smooth Mornay sauce for festive occasions.

# What You'll Need:

→ For the Sliders

01 - 12 mini brioche slider buns, sliced
02 - 12 slices roasted turkey breast (14 ounces)
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

# Directions:

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, whisking constantly to avoid lumps. Cook until thickened, approximately 3–4 minutes.
02 - Remove from heat and stir in cheddar and 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 down and toast until golden, 1–2 minutes.
04 - Place the bottom halves of the toasted buns on a baking sheet. Layer each with a slice of turkey, a 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, sprinkle with parsley and smoked paprika if using. Top each slider with the top half of the brioche bun and serve immediately while warm.

# Expert Hints:

01 -
  • They're elegant enough to impress but casual enough to make on a Tuesday afternoon.
  • The creamy Mornay sauce is addictive and absolutely foolproof once you learn the roux trick.
  • You can prep everything ahead and broil them right before guests arrive—minimal last-minute stress.
02 -
  • Never add cold cheese directly to a hot sauce—it seizes up and breaks; always take the pan off heat first.
  • Slicing your tomatoes thin and placing them on a paper towel for a minute draws out excess moisture that would otherwise make your sliders soggy.
03 -
  • Keep your Mornay warm in a double boiler if you're making these in batches so it doesn't cool down and become lumpy.
  • Slice your bacon while it's still warm from cooking because it's easier to cut cleanly and you'll avoid crumbling it into sad little pieces.
