Can I make Hot Brown Sliders ahead of time?
Yes. Assemble the sliders (before adding sauce) up to 4 hours ahead, cover, and refrigerate. Pour warm Mornay sauce over just before baking.
What can I use instead of white cheddar cheese?
Gruyère, Swiss, or a sharp cheddar work well. Avoid pre-shredded cheese with anti-caking agents, which can make the sauce grainy.
How do I know when the sliders are done baking?
Bake until the cheese sauce is bubbly around the edges and the tops are golden, usually 12–15 minutes at 375°F.
Can I use rotisserie chicken instead of deli turkey?
Yes, shredded rotisserie chicken works as a substitute. Use about 1.5 cups shredded meat to account for moisture differences.
What's the best way to reheat leftover sliders?
Cover with foil and warm in a 325°F oven for 10–12 minutes until heated through. Avoid the microwave, which can make the rolls rubbery.
