Kentucky Derby Hot Brown Sliders (Printable Version)

Mini brioche buns with turkey, bacon, tomato, and rich cheese sauce for a flavorful party treat.

# The Ingredients You'll Need:

→ For the Sliders

01 - 12 mini brioche slider buns, sliced
02 - 12 slices roasted turkey breast, approximately 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

# Step-by-Step Instructions:

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 prevent 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 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 a slice of turkey, a tomato slice, and 1 tablespoon of Mornay sauce. Top with one half 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 parsley and smoked paprika if desired. Top each slider with the top half of the brioche bun and serve immediately while warm.

# Additional Tips::

01 -
  • They look fancy enough to serve at a proper Derby party but taste like the coziest Southern comfort food you've ever had.
  • The Mornay sauce is silky and rich without being heavy, and the contrast with crispy bacon and tender turkey keeps every bite interesting.
  • You can prep the sauce ahead and assemble everything in minutes, which means less time in the kitchen and more time enjoying the festivities.
02 -
  • Don't skip whisking the roux and liquid together—lumpy Mornay is heartbreaking and there's no fixing it once it happens.
  • The broiler trick of cooking just the bottoms before topping means your buns won't dry out or burn, and the sauce gets hot and bubbly without overcooking the meat.
03 -
  • Make your Mornay sauce up to four hours ahead and reheat it gently in a double boiler—this takes stress off your timing when guests arrive.
  • Toast your buns right before assembly so they're still steaming warm and won't absorb moisture from the sauce too quickly.
