This is one of those dishes I threw together, and was very surprised at how tasty it was. These are savory waffles made with sourdough starter and no sugar. The other secret ingredient is the wonderful Justice from Penzey’s. Seriously, everything needs a little Justice, right?

Waffles done correctly require beaten egg whites. A stand mixer is too big for a couple of egg whites, but a hand-held *eggbeater does the perfect job. A hand-held mixer will also be fine, but if you don’t feel like hauling it out and want a little workout, use an egg beater. You could also make this with buttermilk, as I did with the Buttermilk Waffles with Strawberry Sauce.

The Waffles

These waffles turn out light as feathers, and one of the reasons they are so light is that they are made with sourdough starter. You can use sourdough discard or freshly fed starter, whichever you happen to have on hand. If you don’t have any starter, then add 1 cup of flour and 1/2 cup of water.

The Croque Monsieur

What is a Croque Monsieur

A croque monsieur (French pronunciation: ​[kʁɔk məsjø]) is a hot sandwich made with ham and cheese. The name comes from the French words croque (“crunch”) and monsieur (“mister”).

The dish originated in French cafés and bars as a quick snack. In the early 1900s, bistro owner Michel Lunarca popularized the croque-monsieur.

A croque monsieur is traditionally made with baked or boiled ham and sliced cheese between slices of pain de mie, topped with grated cheese and slightly salted and peppered, and then baked in an oven or fried in a frying pan. The bread may optionally be browned by grilling after being dipped in beaten egg. Traditionally, Gruyère is used, but sometimes Comté or Emmental cheese as well. Some brasseries also add béchamel sauce.


So what we are doing here is substituting a savory waffle for bread. This sandwich is rich, and two waffles will easily serve four people with a salad. Make it tastier by grilling the ham before you assemble it into a sandwich.

How to Use an Eggbeater Transcript

This is an eggbeater. This is what people used to use a long time ago. But they still do a great job. So I’m going to put that in here. And then I’m going to start whipping. As. you can see it’s already starting to get thick. You get a little bit of a workout while you’re doing this. And that’s fine. See? They hold a soft peak. And that’s exactly what we want.
