Welsh Rarebit is a delicious blend of savory ingredients: sharp cheddar, egg yolk, Worcestershire sauce, whole grain mustard and beer, piled onto slabs of toasted bread and broiled into a bubbly cheese sauce. A jammy sweet broiled tomato tops them off, a slight break from tradition that makes these cheese toasts even better.

Why do they call it Welsh Rarebit?
And speaking of tradition, did you know that the Welsh Rarebit began as Welsh Rabbit? The original name caused some confusion considering that no rabbits are now or were ever harmed in the making of it. As Wikipedia explains: “The word rarebit is a corruption of rabbit, “Welsh rabbit” being first recorded in 1725 and the variant “Welsh rarebit” being first recorded in 1785 by Francis Grose.” You may even find it on menus as “English rabbit” or “Scotch rabbit.”
Whatever you call it, it’s absolutely delicious and ready to eat in less than 15 minutes.
You need only three ingredients to make an excellent grilled cheese sandwich: bread, most any variety will do; cheese, as long as it melts; and butter because it really does make everything better. But this isn’t that kind of sandwich. It’s related, but in a rowdy cousin kind of way.
It’s complex, but not complicated. You can easily adjust the recipe to serve two or ten. Serve as an appetizer, or lunch or dinner as a side dish to steaming hot bowls of creamy Tomato Bisque.
Recipe Options
- Use any beer you like here from pale ale to a dark beer like Guinness.
- Spice up the melted cheese mixture with a pinch of hot paprika, cayenne pepper, or a few dashes of hot sauce like Tabasco.
- Swap creamy Dijon mustard in for the whole grain mustard.
How to make Welsh Rarebit
Step 1: Whisk together sharp cheddar, egg yolk, mustard, Worcestershire, and beer. Stir in cheese until coated.

Step 2: Season tomato slices then partially toast bread and tomatoes under broiler.

Step 3: Top toasted bread with cheese mixture.

Step 4: Broil until cheese is bubbly and tomato slices are tender.

step 5: Top broiled cheese mixture with tomatoes and serve.

There would be no going back to the 3 ingredient simple grilled cheese after tasting this beauty! Yum!
haha! Thanks, Sonali. 🙂
I love open faced grilled sandwiches! This meal is perfect for when I don’t know what to cook and don’t have a lot in my fridge. I always have tomatos, cheese and bread!
Me too, Ashley! Staples are a must, don’t you think? 🙂
Yum! The beer + yolk sounds awesome!! Not an ordinary grilled cheese, these look so stunning and I’m craving for some now! 🙂
Thank you, Maggie!
Oh yes, I am currently raising my glass to rowdy cousins! 😉 This is one of my favorites that I don’t make nearly often enough. When I’m trying to be extra healthy I’ll top the bread with wilted spinach before I add the cheese. Love the gorgeous tomato slices on top too!
Great idea, Faith! I’m going to do that next time!
Open faced grilled cheese = more cheese! I’m sooo pumped about this- looks great!
You crack me up, Medha. 🙂 Thank you…
oh my! this is so perfect! I love grilled cheese sandwiches, and to add a tomato is so so perfect! Now I need one of these pronto!
Give it a try! So good, I promise…
I actually prefer to eat my grilled cheese open-faced like this…because then you get to eat DOUBLE THE CHEESE!
Exactly! Thanks, Joanne.
Mmmm sounds indeed rowdy and delicious! I am really liking this and the weather dictates a grilled cheese of this caliber is in order!
Some of the best foods are rowdy and delicious, don’t you think? If your blog is any indication, you agree. 😉 Big flavors going on over there…
Seriously drooling! Cheese and bread are my two favorite foods – so it’s only natural that grilled cheese is my ultimate dish! Love the addition of the beer – it’s like an awesome beer-cheese sandwich 😉
Yes, exactly!
I love a good grilled cheese! Love the addition of tomato here!
Thanks, Sam. 🙂
A grilled cheese sandwich without butter is not a correct grilled cheese! I love my grilled cheeses with tomatoes so this should be riiiight up my alley 🙂
Thanks so much!
Hi Marissa! No better combo than this! I sometimes top my mac n’ cheese with tomatoes. This would make a nice appetizer on party rye bread!
That’s a great idea, Dorothy. I hadn’t considered tomatoes on mac n’cheese, but it sounds so good! And DEFINITELY on party rye…love the way you think. 😉
This looks so delicious! I don’t know if my earlier comment disappeared-it seemed to get eaten up so hopefully this works!
Thanks, Lorraine. Sorry about the comment trouble…I don’t see the other one. xo
Those ingredients totally made my mouth water Marissa! Worcestershire, egg yolk and beer? Along with the cheese and tomatoes? Girl…you know how to BRING IT with a grilled cheese sandwich! When are you serving it next, because I’m coming over! xoxo
Please do! I’ll have one waiting for you… 🙂
I knew this wouldn’t just be a plain ole’ grilled cheese. I’m making this today. Have to!
Made it yesterday, obsessed with it. Making it for dinner tonight 🙂
Nagi, that is awesome!!! So sweet of you to come back and let me know. xoxo
