The classic Kentucky Hot Brown as party bites: turkey and tomato on toasted brioche under bubbly Mornay and bacon.
6 steps, about 34 minutes start to finish.
Cook bacon on parchment-lined sheet pan at 400°F, 14-16 min. Drain and break in half.
Cut brioche into 2-inch rounds. Brush with melted butter. Toast at 400°F for 5-7 min, flipping halfway.
Mornay: Melt 3 tbsp butter, whisk in flour, cook 1-2 min. Slowly whisk in warm milk, then cream. Cook 4-5 min until it coats a spoon.
Off heat, whisk in cheddar and pecorino until melted. Season with nutmeg, white pepper, salt. Temper and add egg yolk if using.
Assemble: brioche round → turkey fold → blotted tomato → generous Mornay → extra pecorino.
Broil 2-4 min until Mornay bubbles and browns. Top with bacon, dust with paprika and parsley. Serve hot.
“Blot your tomato slices on paper towels before assembling: wet tomatoes make soggy bites. The Mornay goes in off heat so the cheese melts smoothly instead of breaking.”
