Authentic Welsh Rarebit
By eatmundo · July 5, 2026
A delightful and comforting British dish, Welsh Rarebit consists of a rich, savoury cheese sauce, often enhanced with ale, mustard, and Worcestershire sauce, generously poured over toasted bread and grilled until bubbling and golden. It’s far more sophisticated than a simple cheese on toast!

- 1
Prepare the Toast: Preheat your grill (broiler) to medium-high. Lightly toast 2-4 slices of thick-cut bread (sourdough or a good quality white loaf works wonderfully) on both sides until golden. This creates a sturdy base for the rich rarebit topping.
- 2
Melt the Butter: In a small saucepan over medium-low heat, melt 25g unsalted butter. Once melted, stir in 1 tablespoon of plain flour and cook for 1 minute, stirring constantly, to create a roux. It should be a pale, paste-like consistency.

Add Liquids and Seasonings: Gradually whisk in 100ml of dark ale or stout (for a traditional flavour, or milk for a milder taste) and 1 tablespoon of Worcestershire sauce. Continue to whisk until the mixture thickens and is smooth, about 2-3 minutes. Bring it to a gentle simmer.

Introduce Cheese and Egg: Remove the pan from the heat. Add 200g grated mature cheddar cheese, 1 teaspoon of Dijon mustard, and a pinch of black pepper. Stir until the cheese is completely melted and smooth. Then, quickly whisk in 1 egg yolk until fully incorporated – this adds richness and helps with binding, but be careful not to scramble the yolk!

Top the Toast: Place the toasted bread slices onto a baking tray. Spoon an even and generous layer of the rarebit mixture over each slice of toast, spreading it right to the edges. Ensure a good coating for maximum deliciousness.

Grill to Perfection: Place the baking tray under the preheated grill. Cook for 2-4 minutes, keeping a close eye on it, until the rarebit topping is bubbling, golden brown, and slightly blistered. The aroma will be incredible!
- 7
Serve Immediately: Carefully remove the rarebit from under the grill. Serve immediately, perhaps with a dash more Worcestershire sauce or a sprinkle of chopped chives, alongside a fresh green salad for a delightful light meal.
Frequently Asked Questions
What type of cheese is traditionally used for Welsh Rarebit?+
Authentic Welsh Rarebit typically calls for a strong, sharp cheddar cheese, or sometimes a blend including Caerphilly or Lancashire, for its rich flavor and excellent melting qualities. This provides the distinctive tangy and savory base of the dish.
What kind of bread is best for Welsh Rarebit, and should it be prepared first?+
A thick-cut, sturdy bread like sourdough or a good quality white bread works best to support the rarebit mixture. It should always be lightly toasted or grilled on both sides before applying the rarebit to prevent it from becoming soggy.
What type of beer should I use for Welsh Rarebit, and are there any non-alcoholic substitutions?+
A traditional Welsh Rarebit benefits from a dark ale, stout, or a rich brown ale, which adds depth and a malty flavor to the cheese sauce. For a non-alcoholic alternative, you can use milk, chicken broth, or even a non-alcoholic beer, though the flavor profile will be slightly different.
How do I properly cook Welsh Rarebit and know when it's done?+
After spreading the cheese mixture onto the toasted bread, grill (broil) it under medium heat until the rarebit is bubbly, golden brown, and slightly caramelized around the edges. Watch it carefully to prevent burning, as it cooks quickly.
