Welsh Rarebit

A thick, savoury cheese sauce spiked with mustard, ale and Worcestershire, spread on toast and grilled until blistered. Not cheese on toast: the cheese is cooked into a sauce first, and it makes all the difference.

How to Make Welsh Rarebit

Tap a step to highlight it, or turn on Cook Mode for large type and step-by-step focus.

  1. Melt the butter, whisk in the flour, and cook 2 minutes over medium heat without colouring.

  2. Add the ale gradually, whisking, then the cream. Simmer 3 minutes until very thick — thicker than a normal sauce.

  3. Turn the heat to low and add the cheese a handful at a time, stirring until each addition has melted before adding more.

  4. Stir in the mustard, Worcestershire, cayenne and black pepper. The mixture should be as thick as soft butter.

  5. Take off the heat, cool for 5 minutes, then beat in the egg yolk.

  6. Cool the mixture completely — it will set to a spreadable paste. It can be refrigerated for up to 3 days at this point.

  7. Toast the bread on both sides until golden and firm.

  8. Spread the rarebit thickly right to the edges of each slice, leaving no bare crust.

  9. Grill under a high heat for 3 to 4 minutes until bubbling and blistered dark brown in patches. Finish with more Worcestershire and chives.

Tips for Success

  • Cool the mixture before spreading. Warm rarebit runs off the toast under the grill.
  • Right to the edges. Exposed crust burns while the middle is still bubbling.
  • For buck rarebit, land a poached egg on top of each finished slice.

Why the Method Is What It Is

Making a roux-based sauce rather than simply melting cheese stops the fat separating under the grill, which is what makes plain cheese on toast greasy. The ale and mustard supply acidity that cuts the fat and keeps the sauce tasting savoury rather than merely rich.

What to Put Next to It

Common Substitutions & Variations

  • In a sauce, full-fat crème fraîche can usually take the place of the double cream; single cream is thinner and more likely to split if it boils, so keep it below a simmer.
