Keto Biscuit Breakfast Sandwich

Keto Biscuit in a Mug + Keto Breakfast Sandwich Recipe

This fluffy, 4 ingredient keto biscuit is so quick and easy—you can make it in the microwave! I’ll show you how to make a microwave keto mug biscuit PLUS one of my simple keto biscuit breakfast sandwich ideas.

All you’ll need is butter, an egg, coconut flour, and some baking powder, mixed together in a mug, microwaved for 90 seconds. That’s it! Simple as that, you’ve got an unbelievably fluffy, comforting keto biscuit ready to slice and serve warm.

Of course, you can probably find low carb and keto biscuit options at some grocery stores if you’d prefer. But let’s be real, this recipe is SO easy, you may have all of the ingredients at home already, and there’s only 1g net carbs per biscuit. Seriously, I was amazed by how tasty this microwave keto mug biscuit turned out, and I love that I don’t need to fuss with the oven or make an entire batch of biscuits.

Feel free to enjoy with butter, doused in gravy, or however you like. My personal fave is a keto biscuit breakfast sandwich with bacon, egg, cheese and avocado! (Recipe is below – or check out my ULTIMATE extra-meaty keto breakfast sandwich recipe!)

Microwave Keto Mug Biscuit

Keto Mug Biscuit Ingredients

1 Tbsp butter
1 egg
1 Tbsp coconut flour
¼ tsp baking powder

Ingredient Notes

This recipe is pretty straightforward! The main thing to keep in mind is DON’T just toss all of these ingredients into the mug at once and then microwave. You’ll need to melt the butter in the mug first, then whisk in the remaining ingredients and cook.

For those with questions about ingredient substitutions, I haven’t personally tried this recipe with any alterations yet! So, I can’t say for sure how any specific substitutions would work out. You’re welcome to experiment with your own ideas if you’d like. (And I’d love if you left a comment at the bottom of the post to share how it goes!)

How to Make Microwave Keto Biscuit in a Mug

First, find a large microwave-safe mug. Think about the size you want your keto biscuit breakfast sandwich to be, because your biscuit will turn out just slightly smaller in size than the base of your mug. Then, add a tablespoon of butter to the mug and microwave until it’s melted. (May take ~30 seconds, depending how cold your butter is.)

Once melted, whisk in the remaining microwave keto biscuit ingredients: an egg, coconut flour, and baking powder. After everything’s integrated, pop the mug back into the microwave for 90 seconds. (This cook time is based on my 1100-watt microwave—timing may vary depending on your machine.)

Finally, allow that cooked keto mug biscuit to cool slightly before turning over the mug, removing the biscuit, and slicing into two rounds! Admire the magic of that fluffy, bread-y texture, and you’re ready to assemble the low carb breakfast sandwich of your dreams.

Easy Keto Biscuit Breakfast Sandwich

1 keto biscuit (see above)
1-2 slices bacon, cooked
1 egg, scrambled into egg patty
1 slice cheddar cheese
½ avocado, sliced
dash of sriracha

Low Carb Breakfast Sandwich Assembly

For those who want some sandwich inspiration, try this bacon egg and cheese + avocado combo. First, start by cooking up 1 or 2 slices of bacon to your desired crispiness. Once they’re ready, set aside on paper towels, but keep some of the bacon fat in that pan to give your egg some extra flavor (and fat)!

Next, whip up a fried egg, or try this hack for a perfect-sized, perfectly round scrambled egg patty! Spray your pan as well as the round outer band of a wide-mouth mason jar lid with cooking spray. Whisk your eggs together in a measuring cup, place the sprayed lid upside down in the pan to form a well, and pour the whisked eggs into it. Cover the pan and allow to cook until egg patty begins to set, then flip the patty and carefully remove the mason jar lid.

If you want to add cheese, now’s the time! Place a slice of your favorite cheese on top of the warm egg patty, cover to help it melt, and remove from the heat. Now you can load up your microwave keto biscuit with all of your cooked sandwich components, along with some sliced avocado, a dash of sriracha, or any toppings you like!

Of course, if you’ve got your own ideas for a keto biscuit breakfast sandwich in mind already, go for it! Use this biscuit however you please. (Or, checkout my ULTIMATE keto breakfast sandwich that’s made for meat lovers—served between homemade sausage patty sandwich ‘buns!’)
