Step 2: 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
- Chicken or turkey
- Firm tofu
- Keto-friendly vegetable – the best low-carb vegetables for sandwiches are:
- Baby spinach leaves
- Gherkins or dill pickles
- Keto-approved fat
- Butter or olive oil or coconut oil – perfect to spread on bread and toast the sandwich.
Step 3: fill and toast
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
- Cheddar cheese
- Mayonnaise or hot sauce or sauce you love
- Baby spinach leaves
- Salt and pepper
Cook the bacon into the skillet until fried and crispy on both sides. Set it aside on a plate.
Next, cook the egg into the skillet in the bacon grease until the white egg is crispy.
Cover with a lid, turn 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.
How to make a vegetarian or vegan keto sandwich?
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 vegetable – spinach, cucumber, olives, tomatoes.

Keto Breakfast Sandwich
An easy keto breakfast sandwich for a low-carb breakfast on the go.
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.
