Keto French Dip Chaffle Sandwich

One way to make following the ketogenic diet more accessible is to explore different recipes, so you don’t get bored. Now that chaffles have hit the keto world like a storm, it has opened many new food options.

As I brainstormed chaffle recipes this week, I thought about one of my favorite sandwiches I have missed since I started eating keto. I knew there had to be a way to make a Low Carb French Dip Sandwich using chaffles for bread. I was right! This Open Faced Keto Chaffle Sandwich turned out fantastic.

What is a Chaffle Sandwich Recipe?

Perhaps you’ve not heard of the chaffles sensation that went viral overnight? If so, the basic recipe is eggs and cheese made into a crunchy cheese waffle with the Dash Mini Waffle Maker. You can also use a regular waffle iron, but the amount of batter and cooking time may need to be adjusted. Since it was first introduced, the keto world has gone crazy, making chaffles of every variety, both sweet and savory; some are even chaffles without the cheese. This recipe is a twist on the standard chaffle recipe that I find a bit crispier and doesn’t taste like eggs.

What is a French Dip Chaffle Sandwich?

Traditional French Dip sandwiches consist of thinly sliced roast beef and melted swiss cheese served on a white sub roll with au jus on the side for dipping. While this sandwich isn’t exactly a traditional French Dip recipe, it is fantastic and easy to make a keto-friendly alternative. Instead of using a carb-laden white sub roll, I substituted a keto chaffle for a deiliocus low-carb crispy bread.

What Beef Did You Use in this Chaffle Sandwich Keto Recipe?

I am a fan of leftovers. With a family of six and a homeschool mom, we eat at home a lot. So that I am not always in the kitchen, I often make extra at dinner, so we have lunch covered for at least the next day. With that in mind, we love slow cooker Keto Pot Roast and enjoy it at least once or twice a month. It’s always nice to repurpose leftovers so that we don’t feel like we aren’t eating the same food the next day. We are turning leftover pot roast into an open-faced low carb French Dip Sandwich made for an incredibly delicious and filling lunch.

First, make two chaffles by following the recipe card at the bottom of this post. I used a combination of mozzarella and cheddar cheeses so that the cheddar wouldn’t overwhelm the roast beef and melted cheese in this chaffle sandwich keto recipe.

Before adding the pot roast on top of the chaffle bread, I made sure to drain it a bit so that the gravy/broth didn’t make the chaffle soggy. You’ll want crunchy bread for this recipe.

While a traditional French Dip sandwich uses swiss cheese, I only had provolone cheese on hand and loved the substitution. Place it on a baking sheet and bake until the cheese has browned.

I decided to make this Keto French Dip Chaffle Sandwich open-faced as it is incredibly hearty and filling. Indeed, comfort food is at its best.

Can I Use a Regular Waffle Maker?

You can, but I have found that the dash waffle maker works best for the crispest chaffles since the grates on the iron are smaller and closer together.

How to Make an Open-Faced Keto French Dip Sandwich

  1. Follow the keto chaffle recipe below on the recipe card
  2. Preheat the oven to 425 degrees. Add 1/3 cup Keto Roast Beef to the top of each chaffle for an open-faced sandwich (I made sure to drain excess broth)
  3. After you add beef, place a slice of deli cheese or shredded cheese on top. (Swiss cheese or Provolone work great)
  4. Place chaffles with meat and cheese in the oven on the top rack to melt the cheese
  5. Serve with a small bowl of beef broth on the side for dipping.
  6. Optional: Some enjoy adding horseradish or mayo to their keto roast beef sandwich.

I poured a little beef broth into a small bowl for dipping, then warmed it up a bit. It was a fantastic accompaniment to this mouthwateringly delicious keto chaffle sandwich.

Can I Make This Easy Keto Recipe Ahead of Time?

You can make chaffles ahead of time. They can be stored in the fridge in an airtight container for up to 5 days or in the freezer for up to 3 months. I suggest not rewarming the chaffle in the microwave as it would lose its crispness from steam. Instead, wrap chaffles in aluminum foil and rewarm in the oven or pop them in the air fryer or toaster.

Servings: 2
Calories: 118kcal
Author: Kasey Trenum

Ingredients

  • 1 egg white
  • 1/4 cup mozzarella cheese, shredded (packed)
  • 1/4 cup sharp cheddar cheese, shredded (packed)
  • 3/4 tsp water
  • 1 tsp coconut flour
  • 1/4 tsp baking powder
  • pinch of salt

Instructions

  • Preheat the oven to 425 degrees. Plug the Dash Mini Waffle Maker in the wall and grease lightly once it is hot.
  • Combine all of the ingredients in a bowl and stir to combine.
  • Spoon 1/2 of the batter on the waffle maker and close the lid. Set a timer for 4 minutes, and do not lift the top until the cooking time is complete. Lifting beforehand can cause the Chaffle keto sandwich recipe to separate and stick to the waffle iron. It is essential to let it cook for the entire 4 minutes before lifting the lid.
  • Remove the chaffle from the waffle iron and set it aside. Repeat the same steps above with the rest of the chaffle batter.
  • Cover a cookie sheet with parchment paper and place chaffles a few inches apart.
  • Add 1/4 to 1/3 cup of the slow cooker keto roast beef from the following recipe. Drain the excess broth/gravy before adding it to the top of the chaffle. (slow cooker Keto Pot Roast recipe here or Instant Pot Keto Pot Roast recipe here)
  • Add a slice of deli cheese or shredded cheese on top. Swiss and provolone are both great options.
  • Place on the top rack of the oven for 5 minutes so that the cheese can melt. If you'd like the cheese to bubble and begin to brown, turn the oven to broil for 1 min. (The swiss cheese may not brown)
  • Enjoy open-faced with a small bowl of beef broth for dipping.
