What Is Welsh Rarebit?
Welsh Rarebit is a traditional British dish made with a smooth, savory cheese sauce poured over toasted bread and then grilled until bubbling and golden. Unlike ordinary cheese on toast, the cheese is first transformed into a sauce using butter, flour, milk, mustard, and seasoning before being melted over bread.
The result? A toast topping that is:
- Creamy instead of greasy
- Deeply savory instead of flat
- Balanced rather than overly salty
Why Welsh Rarebit Is Not “Just Cheese on Toast”
Calling Welsh Rarebit “cheese on toast” is like calling lasagna “pasta with sauce.” Yes, the components are similar—but the technique and outcome are completely different.
Welsh Rarebit:
- Uses a cheese sauce, not sliced cheese
- Is seasoned and layered with flavor
- Has a silky, spreadable texture
- Delivers consistent results every time
The History of Welsh Rarebit
Welsh Rarebit dates back to 18th-century Britain, particularly Wales, where cheese was plentiful and meat was expensive. It became a clever way to turn simple ingredients into a filling meal.
From “Welsh Rabbit” to Welsh Rarebit
Despite the name “Welsh Rabbit,” the dish contains no rabbit at all. The name was likely humorous or ironic, implying that cheese was the Welsh equivalent of meat. Over time, “rabbit” evolved into “rarebit,” and the name stuck.

Step-by-Step Guide to Making Welsh Rarebit
Step 1 – Preparing the Bread
Toast the bread lightly on both sides. This creates a barrier so the sauce doesn’t soak in.
Step 2 – Making the Cheese Sauce Base
Melt butter in a saucepan over medium heat. Add flour and stir continuously for 1–2 minutes to form a roux.
Step 3 – Adding Flavor and Depth
Gradually whisk in milk until smooth. Add mustard, pepper, and salt.
Step 4 – Thickening the Sauce
Continue stirring until the sauce thickens enough to coat the back of a spoon.
Step 5 – Combining Cheese and Sauce
Lower the heat and add grated cheese gradually, stirring until fully melted.
Step 6 – Assembling the Toast
Spread the cheese sauce generously over toasted bread.
Step 7 – Grilling to Perfection
Place under a hot grill until bubbling and golden on top.
Common Mistakes to Avoid
Overheating the Cheese
High heat can cause cheese to split. Always melt gently.
Using the Wrong Bread
Soft bread leads to soggy results.
Skipping the Mustard
Mustard enhances cheese flavor—it’s essential, not optional.
