A FLAVORFUL HANDHELD SANDWICH RECIPE

Kentucky Hot Brown Sliders are a delicious twist on the classic Hot Brown sandwich. These handheld sliders are so unique and are a little sweet and a little savory. What really sets these mini sandwiches apart is the cheesy sauce (called a mornay sauce)! Y’all, this cheese sauce is out-of-this-world good! Don’t look at the ingredients and scroll away – I know it’s tempting but I promise it is 100% worth it! It’s not as hard or as fancy as it sounds, but it really makes these sandwiches incredible.

FREQUENTLY ASKED QUESTIONS (FAQ’S): 

What is a Kentucky Hot Brown?

A Kentucky Hot Brown is a classic American open-faced sandwich that originated in Louisville, Kentucky. It is traditionally made with sliced turkey, bacon, and Mornay sauce. The sandwich is typically served on toasted bread and topped with tomato slices and grated Parmesan cheese. The Kentucky Hot Brown is then broiled until the cheese is melted and bubbly. Most of us are familiar with this sandwich as it is very popular to serve at the Kentucky Derby.

What is Mornay Sauce?

Mornay sauce is the white cheese sauce that we make for these sliders. I call it a cheese sauce so it’s less intimidating. It’s the perfect topping for your Kentucky Hot Brown Sliders.

Do I have to make a cheese sauce?

Of course not. If you don’t have the time or energy you can just get some good melty cheese to put on top. Velveeta makes a queso blanco cheese that you could melt and use on top of these.

What if I don’t have Gruyere cheese?

No problem. Try some mozzarella, Swiss, Gouda, or white cheddar in its place.

How to reheat leftovers?

Cover any leftovers with aluminum foil to reheat in the oven. If you don’t cover them, they’ll burn. Alternatively, you can use the microwave.

How to store leftovers?

Leftovers should be stored in an airtight container or bag in the refrigerator for up to 3 days. Leftovers can also be frozen for up to 3 months as well.

INGREDIENTS NEEDED: (SEE RECIPE CARD BELOW FOR THE FULL RECIPE)

  • salted butter and all purpose flour – these combine to make the roux to thicken the cream sauce.
  • nutmeg – nutmeg is a classi ingredient in a Mornay sauce. It is not strong but adds that special something in the background that really sets this sauce apart. You can leave it out if you prefer.
  • whole milk – whole milk really makes a difference in creaminess. The more fat, the more creamy the sauce will be. You can use a 2% milk if you must but do not use a skim milk.
  • shredded gruyere cheese – I talk about substitutions above in the FAQ section.
  • Hawaiian rolls – we like the sweetness these adds but you could certainly use dinner rolls.
  • sliced deli turkey– can use any leftover turkey meat or even chicken if you prefer.
  • bacon– if you don’t want to take the time to cook up some bacon, you can use the store-bought bacon pieces that come in those little bags (usually found where salad toppings are located in your grocery store.)
  • light brown sugar, dijon mustard, Worcestershire sauce, dried onion flakes, garlic powder – these combine to make the glaze. You can tailor this to your tastes and remove any ingredient you do not like.

HOW TO MAKE KENTUCKY HOT BROWN SLIDERS

Preheat the oven to 375°F. Spray a 9×13-inch baking dish with nonstick cooking spray and set aside. Make the cheese sauce first. Melt the butter in a small saucepan. Whisk in the flour, salt, pepper, and nutmeg until smooth. Cook for 1 minute. Slowly stream in the milk while whisking constantly.

Slice the Hawaiian rolls in half lengthwise. Place the bottom half of the rolls, cut side up into the prepared baking dish. Layer the turkey on top of the rolls.

Then layer the crispy bacon on top of the turkey. Dollop the cheese sauce over the top and gently spread it out.

Place the other half of the rolls on top. In a separate small bowl, stir together the butter, brown sugar, dijon, Worcestershire, onion flakes, and garlic powder until well combined.

Brush the butter mixture all over the rolls. It may seem like too much but use it all. Cover with nonstick foil (or spray foil with nonstick cooking spray) and cover the baking dish. If possible, try not to let the aluminum foil touch the tops of the rolls. Bake for about 20 minutes. Uncover and then bake an additional 5 minutes or until the rolls are browned on top.

    Fantastic recipe. I am lucky enough to have eaten this sandwich twice at the famous Brown Hotel in Louisville. Your recipe is great. I have not eaten it with guyere. Only with parmesan and romano.
