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.

Ingredients  

  • 1 teaspoon whole-grain mustard
  • 1 egg yolk
  • 2 tablespoons beer
  • 1/2 teaspoon Worcestershire sauce
  • kosher salt and freshly ground black pepper to taste
  • 4 ounces shredded sharp cheddar cheese
  • 2 thick slices rustic sourdough loaf about 1-inch thick
  • 4 slices Roma tomato about 1/4-inch thick
  • 2 teaspoons olive oil
  • kosher salt and freshly ground black pepper to taste

Instructions 

  • Preheat broiler.
  • In a medium bowl, whisk together mustard, egg yolk, beer and Worcestershire sauce. Season lightly with salt and freshly ground black pepper. Stir in shredded cheddar until well blended (the cheese should be uniformly wet with no liquid remaining on the bottom of the bowl.).
  • Arrange bread slices and tomato slices on a baking sheet. Drizzle tomato slices with olive oil and season with salt and pepper. Broil 3 minutes until bread is a light golden brown.
  • Remove from broiler and spread cheese mixture evenly over each bread slice, all the way to the edges. Broil until melted and bubbly, 3 to 4 minutes more.
  • Top of each bread slice with two broiled tomato slices on and serve immediately.

    There would be no going back to the 3 ingredient simple grilled cheese after tasting this beauty! Yum!

    1. Marissa says:

      haha! Thanks, Sonali. 🙂

  2. Ashley | Spoonful of Flavor says:

    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!

    1. Marissa says:

      Me too, Ashley! Staples are a must, don’t you think? 🙂

  3. Maggie | Omnivore's Cookbook says:

    Yum! The beer + yolk sounds awesome!! Not an ordinary grilled cheese, these look so stunning and I’m craving for some now! 🙂

    1. Marissa says:

      Thank you, Maggie!

  4. Faith (An Edible Mosaic) says:

    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!

    1. Marissa says:

      Great idea, Faith! I’m going to do that next time!

  5. whiskandshout says:

    Open faced grilled cheese = more cheese! I’m sooo pumped about this- looks great!

    1. Marissa says:

      You crack me up, Medha. 🙂 Thank you…

  6. Mon Petit Four says:

    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!

    1. Marissa says:

      Give it a try! So good, I promise…

  7. Joanne says:

    I actually prefer to eat my grilled cheese open-faced like this…because then you get to eat DOUBLE THE CHEESE!

    1. Marissa says:

      Exactly! Thanks, Joanne.

  8. KevinIsCooking says:

    Mmmm sounds indeed rowdy and delicious! I am really liking this and the weather dictates a grilled cheese of this caliber is in order!

    1. Marissa says:

      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…

  9. HapaNomNom says:

    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 😉

    1. Marissa says:

      Yes, exactly!

  10. Sam - SugarSpunRun says:

    I love a good grilled cheese! Love the addition of tomato here!

    1. Marissa says:

      Thanks, Sam. 🙂

  11. Girl and the Kitchen says:

    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 🙂

    1. Marissa says:

      Thanks so much!

  12. Dorothy Dunton says:

    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!

    1. Marissa says:

      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. 😉

  13. Lorraine @ Not Quite Nigella says:

    This looks so delicious! I don’t know if my earlier comment disappeared-it seemed to get eaten up so hopefully this works!

    1. Marissa says:

      Thanks, Lorraine. Sorry about the comment trouble…I don’t see the other one. xo

  14. Kristi says:

    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

    1. Marissa says:

      Please do! I’ll have one waiting for you… 🙂

  15. Nagi@RecipeTinEats says:

    I knew this wouldn’t just be a plain ole’ grilled cheese. I’m making this today. Have to!

    1. nagimaehashi says:

      Made it yesterday, obsessed with it. Making it for dinner tonight 🙂

      1. Marissa says:

        Nagi, that is awesome!!! So sweet of you to come back and let me know. xoxo
