Kentucky Hot Brown — Ad-Free Recipe, Ingredients First

This Louisville hotel classic lives or dies on the Mornay, so real milk and a good grating cheese matter more than anything else on the plate. Cook the butter-flour roux a full two minutes before you add the milk. Then melt the cheese in off the heat, which keeps the sauce glossy rather than grainy.

The Ingredients — and where to get them

Straight Answers

Can you make Kentucky Hot Brown in an air fryer? — Yes

Yes — this is exactly what an air fryer does well. Work in a single layer so the air can move, and shake or flip halfway for even crisping. It runs a touch faster than the oven, so check early.

Can you freeze Kentucky Hot Brown? — Yes

Yes — it freezes well. Cool it fully, portion into airtight containers, and it keeps a few months; thaw in the fridge and reheat gently.

Can you make Kentucky Hot Brown ahead of time? — Best fresh

Best made fresh and served soon — it loses its edge standing around. You can prep the parts ahead, but finish and serve it close to the table.

Is Kentucky Hot Brown gluten-free? — Not as written

Not as written — it contains gluten. Make it gluten-free: swap in gluten-free versions of the wheat items (check the other labels too).

Is Kentucky Hot Brown vegan? — No

No — it contains meat, so it isn’t vegetarian or vegan.
