This is just a quick overview of how to make a keto omelet in a mug. For the recipe in detail, scroll to the recipe card at the end of the post.

I don’t know about you, but I just love the whole “in a mug” trend that has taken off over the past several years. After you give this recipe a try, you’ll have to try my favorite keto mug recipe: a keto pancake in a mug!

To make this mug omelet, lightly spray the inside of a microwave-safe mug with non-stick cooking spray.

Then add the egg, cheeses, salt and pepper, and veggies.

Microwave for 1 minute, 45 seconds on high and check for doneness. If not yet cooked through, continue to cook in 15-second increments, keeping in mind that the high cheese content of this omelet will make it look a bit wet when hot. TIP: Do not overcook. When cooled off, it will firm up.

How to Make a Keto Omelet in a Waffle Maker (Version 2)

This is just a quick overview of how to make a keto waffle omelet. For the recipe in detail, scroll to the recipe card at the end of the post.

This version takes a tiny bit more prep and clean-up work, but it will give you a yummy and crispy keto omelet. To make this version, I highly recommend using the Dash Mini Waffle Maker. You can get one of your own below:

Get the Dash Mini Waffle Maker!

Using a Dash Mini Waffle Maker will yield two mini waffles…  or should I say “womelets”? 😉 If you use a regular-sized waffle maker, you’ll likely yield one waffle.

Mix the ingredients just like you would for the mug version, then pour the mixture onto a pre-heated waffle maker that has been lightly sprayed with non-stick cooking spray. TIP: If using a mini waffle maker, you will need to divide the batter in half.

How to Make Keto Meal Prep Omelets

You can continue to make single-serve keto omelets using the process outlined in this post. Or, you can make my Keto 3-Cheese Mini Quiches, which is almost this exact recipe made in muffin tin form. Two mini quiches = a single serving of this keto omelet.

Is it Keto Omelet or Keto Omelette?

Have you ever wondered to yourself: “Is it omelet or omelette?” I admit that “omelet” drives me nuts because it looks so unsophisticated next to “omelette.” 😉 Here’s the difference:

  • Omelet is the American English spelling.
  • Omelette is the British English spelling, which also happens to be the modern French spelling.

According to Grammarly, “omelet” originated in the 17th century in France and became the version adopted in American English.
