This recipe is a ketoized version of a HUGELY popular sandwich we’d make when I had my deli. We have perfected the art of making the French Dip, and turning it keto was as simple as swapping out the bread to make a chaffwich.

What’s a chaffwich? A chaffwich is a sandwich made with a chaffle! If you’ve got a Dash mini waffle maker, then you’re most of the way there to making a scrumptious lunch. Read on, and I’ll show you how to make this easy and flavorful quick lunch or light supper.

What’s a Dash Mini Waffle Maker?

Perfect for making chaffles, a combination of cheese and waffle, chaffles took the keto world by storm. A simple batter is made from eggs, cheese, and a few other ingredients (see recipe card below) and they cook up light and crispy in a Dash mini waffle maker.

This appliance is tiny! It’ll tuck away nicely in a drawer, so it won’t take up much space.

And, it’s affordable. Amazon sells Dash products pretty cheaply.

What You Need to Make a Keto French Dip Chaffwich

Ingredients to Make a Keto French Dip Chaffwich

  • deli sliced roast beef or leftover roast beef
  • egg whites
  • almond flour
  • mozzarella cheese
  • sour cream
  • low sodium beef broth
  • (optional) Swiss or provolone cheese

How to Make a Keto French Dip Chaffwich

There are really two steps to making a keto French Dip Chaffwich.

  1. Make the chaffle.
  2. Heat the roast beef in the warmed broth.

That’s it! Super simple.

Chef Jenn’s Tips

  • Chaffles can be made ahead of time. Cook them, cool them, and then reheat them in the toaster or in the mini waffle maker for a few minutes before assembling the sandwich.
  • Au jus packets are loaded with sodium and hidden carbs. Just look at the ingredient label. Ouch! Instead, use low sodium beef broth for dipping and skip the carbs and extra sodium.
  • Some French dip sandwiches are served with a smear of mayo and melted cheese. This is optional and up to you. I’ve even seen some with horseradish on them.

What To Serve With a Keto French Dip Chaffwich

I’m a sucker for soup and sandwich combos, and my Wonton-less Soup or Grandma’s Chicken Zoodle Soup would pair beautifully with this meal. This beefy Minestrone Soup is another good pick.

Or, serve your chaffwich with a salad. A small Cobb Salad is a great pick.

Will A Keto French Dip Chaffwich Freeze?

You can freeze chaffles (and toast them in the toaster before using) and you can freeze the beef in the broth. I wouldn’t freeze assembled chaffwiches, though, as they’d turn into a soggy mess during heating.

How many net carbs are in this keto French Dip Chaffwich?

There are 4 net carbs in this dish.

What do I do if I don’t have a Dash Mini Waffle Maker?

You can use a regular waffle maker – just use all the batter and then cut the waffle in half.

What kind of beef should I use?

You can use thinly sliced roast beef from your deli, or use thinly sliced leftover roast beef. Pulled beef or beef from a pot roast cooked in the slow cooker would also work.

  • 4 ounces roast beef
  • 2 egg whites
  • 2 tbsp almond flour
  • 1 tbsp sour cream
  • 1/2 cup mozzarella
  • 1/2 cup low sodium beef broth


  • To prepare the chaffle, whip the egg white until frothy. Add the sour cream and almond flour and blend well. Mix in the cheese.
  • Preheat the mini waffle maker as per manufacturer’s directions. When hot, add half the batter and cook for 7-10 minutes or until the chaffle is golden brown and releases easily. Repeat with the remaining batter.
  • Meanwhile, warm the beef broth in a small skillet or pot. Add the sliced beef to heat through – but don’t over cook it!
  • To assemble, place the drained beef on the chaffle, top with cheese (optional) and serve with the remaining broth on the side.

  1. This is genius! Easy, delicious, and caters to the French dip cravings, but keto! Love it…thanks for sharing 🙂

  2. I used to love waffle sandwiches and would love to try this but I have a severe egg intolerance. Do you have a suggestion for a substitute for the egg whites in your chaffwich? I do have the store bought egg substitute mix; I haven’t used it yet. Do you think it would work? Thank you.

    • I just don’t know how well these would work without the egg. The egg acts as a binder, so if your egg sub mix also works as a binder, the chaffles may work out. Let me know how they turn out!

    Oh my word! What a delicious idea – hubby who’s partially in the keto diet would totally love this!

  4. 5 stars
    I love how we’re finding ways to get more out of otherwise single-purpose appliances. Thanks for sharing!

    • Right? I hate one trick pony appliances! If it can’t do more than one job, there’s no room for it (literally) in my kitchen!

  5. 5 stars
    For years I have slow cooked my pot roast with 1 can beef broth and seasonings then shredded it to make french dips sandwiches, using the broth for aujus. But since going low carb we thought we would never get to enjoy them again! These chaffles are a game changer, am making them tonight for the third time. They are incredibly easy and so good. Thank you, thank you! Love you girl and love your recipes.

    • Thanks for dropping by to comment – you made my day! I’m so glad you’re enjoying the chaffles and my recipes! I’ve got a new crispy chaffle recipe out, have you seen that one yet? They’re my new favorites!
