What Is A Keto Breakfast Sandwich?

How To Make A Keto Breakfast Sandwich

It’s very easy to make a low-carb breakfast sandwich at home in a sandwich press maker.


While you can pick any of the ingredients below for your sandwich, my favorite options are the one just below – my 90-second keto bread with a bacon and egg filling.

  • Almond Flour – For the 90-secomd keto bread.
  • Coconut Flour – or 2 tablespoons extra almond flour.
  • Baking Powder
  • Extra Virgin Olive Oil or melted butter
  • Egg – pick large free-range eggs for the bread.
  • Water
  • Bacon – pick your favorite bacon cut.
  • Egg – Any size works, I use my Sunny Side Up Eggs
  • Mayonnaise
  • Baby Spinach
  • Cheddar Cheese – or your favorite tasty cheese
  • Butter

Filling And Toasting

Now that you selected all the ingredients for your low-carb sandwich, it is super easy to assemble.

First, spread butter on the outside of both slices of keto bread – these sides are going to be toasted in a skillet or in the sandwich press. Set aside.

To make a bacon and egg sandwich, as seen in my picture, you need:

  • Keto bread
  • Bacon
  • Egg
  • Cheddar cheese
  • Mayonnaise or hot sauce or sauce you love
  • Baby spinach leaves
  • Salt and pepper
  • Butter

Cook the bacon in the skillet until fried and crispy on both sides. Set it aside on a plate.

Next, cook the egg in the skillet in the bacon grease until the white egg is crispy.

Cover with a lid, turn the skillet over medium heat, and set aside until the egg yolk is half cooked. This is optional, but it sets the egg yolk slightly and makes it easier to hold in a sandwich.

Next, top up the first bread slice with a layer of cheese, followed by meat, vegetable, and cheese, and repeat to add more if desired.

Choosing Keto Bread

First, choose the keto bread recipe you want to use. You have a few options based on the time you want to spend in the kitchen and your food allergies.

All homemade keto bread loaves are made with keto flour, including almond flour, coconut flour, or sunflower seed flour for a nut-free option.

Pick the recipe that matches your preference below, or buy store-bought keto bread at the store.

Microwave Bread

For a quick and easy bread, make a 90-second keto bread following one of the recipes below:

Egg-Free Keto Bread Loaf

These keto bread loaf recipes are also vegan keto-approved as they are egg-free and dairy-free. They also freeze very well to meal prep some keto sandwiches.

Everyday Keto Bread Loaf

If you don’t mind the eggs in a keto bread loaf, try some of the keto bread loaf recipes below.

They all slice perfectly to make a delicious breakfast sandwich low-carb recipe.

Low-Carb Sandwich Filling

Next, choose the keto sandwich filling you want to add to your breakfast sandwich.

As a general rule, to make a fulfilling breakfast  keto sandwich, you must pick 1 or 2:

Keto Protein

The best options are:

  • Slice of cheese
  • Ham
  • Chorizo
  • Bacon
  • Chicken or turkey
  • Mushrooms
  • Firm tofu
  • Tempeh

Keto-Friendly Vegetables

The best low-carb vegetables for sandwiches are:

  • Baby spinach leaves
  • Lettuce

  • Bacon
  • Cheese
  • Avocado

This is a perfect savory breakfast served with your favorite coffee, tea, or cottage cheese smoothie.

It’s also a great quick lunch for when you don’t have time to cook something fancy.

Storage Instructions

This Keto Breakfast Sandwich is best served and eaten immediately.

However, when I make it, I tend to have some ingredient leftovers.

The bread can be kept for a few days in the fridge and reheated in toasted.

The bacon and egg can be kept in an airtight container in the fridge and warmed up on a frying pan.

Allergy Swaps

To make a vegetarian sandwich, simply add some of these ingredients :

  • Protein: fried egg or, if vegan, use fried mushrooms or firm tofu slices.
  • Fat: cheese or if vegan keto, use vegan cheese or avocado.
  • Keto vegetables – spinach, cucumber, olives, tomatoes.

  • First, prepare your keto bread recipe following one of my keto bread recipes on the blog.
  • Lay 2 slices of keto bread on a plate, spread half the butter on each outside part of the bread slices. Set aside on the plate, buttered side face down.
  • Spread half the mayonnaise on each bread slice facing you. Set aside.
  • Meanwhile, fry the bacon slices over medium heat in a skillet. When cooked and crispy, set aside on a plate.
  • Cook the egg in the bacon fat until crispy. Cover with a lid and cook 1-2 minutes to slightly set the center of the egg – this is optional, but the egg yolk is less runny and holds better in the sandwich with this technique.
  • Warm the sandwich press and meanwhile assemble the sandwich.
  • Lay half a cheese slice, crispy bacon, fried egg, spinach leaves, and the remaining cheese slice. Top up with the second slice of bread, butter side out.
  • Place the sandwich in the press or on the skillet over medium heat and cook on both sides until the cheese is melted and the bread golden brown.
  • Serve immediately.

The nutrition data is calculated using WP Recipe Maker. Net Carbs is calculated by removing the fiber and some sweeteners from the total Carbohydrates. As an example, a recipe with 10 grams of Carbs per 100 grams that contains 3 grams of erythritol and 5 grams of fiber will have a net carbs content of 2 grams. Some sweeteners are excluded because they are not metabolized.
