This delicious and filling keto breakfast sandwich hits the spot when you miss "the way you used to eat."
It's made with toasted slices of a quick microwave coconut flour bread. Layers of cheese, ham, and fried egg complete the delicious experience.
This keto breakfast sandwich is delicious, substantial, and filling. Breakfast may not be the most important meal of the day, but it's my favorite meal. Low-carb or not, I strive to make it good!
The basis for this sandwich is 90-second bread. It's so wonderfully versatile that I use it whenever I want a bread substitute. It's much easier to make than cloud bread, which is excellent but more labor-intensive.

Ingredients
You'll only need a few simple ingredients to make this keto breakfast sandwich. The exact measurements are included in the recipe card below. Here's an overview of what you'll need:
For the bread:
- Butter: I use salted butter in this recipe. You can use unsalted butter and add a pinch of salt.
- Egg: I use large eggs in almost all my recipes, this one included.
- Coconut flour: Try to measure it by weight and not by volume. It's extremely absorbent, so each extra gram makes a difference.
- Baking powder: Make sure it's fresh. And if you need it to be gluten-free, verify that as well.
For the sandwich:
- Olive oil spray: I use it to cook the egg and toast the bread.
- Egg: Again, I use a large egg since that's what I typically have on hand.
- A slice of cheese: I like to use sharp cheddar cheese.
- A slice of deli ham: A thick slice works best in this recipe.
Variations
The best way to vary this recipe is to use different cheeses. I love sharp cheddar, but other tasty options include gouda (my personal favorite), provolone, and smoked mozzarella.
You can also use a different bread as the base for this sandwich. I sometimes use this keto English muffin.
Lastly, instead of deli ham, you can use Canadian bacon. It's fully cooked, so it's your choice whether you want to cook it before adding it to the sandwich. I usually don't.
Instructions
Making this keto breakfast sandwich is easy! Scroll down to the recipe card for detailed instructions. Here's an overview of the steps:
Make the keto bread. Melt the butter in a ramekin or shallow bowl, mix in the remaining bread ingredients, and microwave the mixture for 90 seconds. Let the bread slightly cool, then slice it into two slices.
Assemble the sandwich. Start with a slice of bread, topped with cheese, ham, and an egg, and then add the second slice of bread.
Expert Tip
When making this recipe, I make the 90-second keto bread in a slightly larger bowl (4 inches on the bottom) than the original recipe calls for. This ensures large enough bread slices to accommodate the filling. Although it also means thinner bread slices.
When I feel like splurging, I make two keto breads. I then use one as the bottom layer and one as the top layer of the sandwich.
So rather than make one piece of bread and slice it into two thin slices, I make two pieces of bread. This gives me a thick, substantial sandwich.
Recipe FAQs
Do I really need to toast the bread?
Yes. Since the bread is a bit eggy and spongy, I go through the extra step of toasting it in a greased skillet. It makes a big difference!
Although, on particularly lazy mornings, I make this sandwich without toasting the bread, and it is still very good.
Is this a make-ahead recipe?
It's possible to make this sandwich the night before, wrap it and refrigerate it, then microwave it in the morning.
But it's not as good as when made fresh. That's why I mostly make it on weekends when I have more time in the morning.
Can you eat a sandwich on the keto diet?
You can, as long as you use low-carb bread such as 90-second bread, keto English muffin, almond flour bread, or a lettuce wrap.
Serving Suggestions
This tasty sandwich makes a complete meal! Simply serve it with some coffee.
Sometimes, I slice a beefsteak tomato into thick slices, sprinkle it with coarse salt, and serve it on the side. A bowl of berries is another delicious side to this sandwich.
Storing Leftovers
You can store this sandwich, wrapped in plastic wrap, in the fridge for 1-2 days and reheat it in the microwave (remove the wrap first). But ideally, it should be eaten fresh.

I'll admit to being suspicious of the "bread" part of this recipe before I made it lol, but OMG, this was absolutely delicious, and the bread tasted like an English muffin. It is the perfect and filling morning sandwich. Definitely putting this recipe on my morning rotation!Reply
