Keto Sandwich

When it comes to quick and easy keto lunch recipes, my favorites to make are quesadillas, mac and cheese, and this keto sandwich. 

Growing up, sandwiches were easily one of my most eaten meals. During school days, my mom would pack me a sandwich of some sort, and some mornings, I’d also have a breakfast sandwich. On busy weeknights where both my parents were working late, it was not uncommon for us to again, have sandwiches, as they were quick and easy to prepare, and use up all the leftovers in the fridge.

When I first started a keto diet, most supermarkets and grocery stores didn’t stock any lower carb kinds of bread. The few that did have some options were still VERY high in carbs and would easily have kicked someone out of ketosis. Luckily, there are now plenty of options available in-store and even more online. Some mainstream brands are also now coming up with their own low carb versions of their popular bread. Looking at my diet now versus what I ate growing up, I don’t actually see too much of a difference, and having sandwiches again has made quite the impact! 

I’ve been meaning to share keto sandwich recipes for quite some time. I know it might sound incredibly obvious, but many people fail to realize how easily accessible keto bread is! Not only that, but you can also easily make your own and have delicious sandwiches every single day!

There is no wheat or flour in the bread, and you can enjoy all your favorite textures and flavors– Crisp vegetables, creamy avocado, and endless protein options. Or, you could even go the sweet route, like some healthy Nutella or almond butter

The other week, I made sandwiches for several of my friends when we went on a picnic and NO ONE believed me when I told them they were low carb- It goes against everything they had believed to be part of a keto diet!

How do you make a keto breakfast sandwich?

The Ingredients

  • Bread– Use your favorite low carb bread, including Aldi or Thin Slim foods. Alternatively, you can make some keto bread.
  • Avocado– A breakfast staple and fantastic replacement for mayonnaise or dressings. I love using homemade guacamole
  • Salad vegetables– I kept it simple with tomato and baby spinach, but cucumber, onions, and peppers are other fantastic low carb options. 
  • Cheese– Optional, but what good breakfast sandwich doesn’t have cheese in it? 

The Instructions

Start by lightly toasting your keto bread.  Once toasted, on one piece of bread, spread a generous portion of avocado, followed by your vegetables and cheese. Top with the remaining piece of bread and slice in half and serve.

Tips to make the best low carb sandwich

  • Always toast your bread before adding the fillings. Most keto bread varieties tend to taste much better and more ‘bread-like’ once toasted. 
  • Keto sandwiches tend to be slightly denser than traditional sandwiches made with flour-based bread. As such, it is important to have some spreadable filling in it (like we did with the avocado). Cream cheese and mayonnaise are two other fantastic options. 
  • For a toasted sandwich, you can omit pre-toasting your bread and simply place it in the sandwich press once it has been assembled.

Keto sandwich ideas

Like any sandwich, there are tons of sweet and savory options. Here are some options to get you started!

  • Egg sandwich– Either fried eggs or some creamy egg salad
  • Chicken sandwich– Chopped chicken breast, celery, almonds, and mayonnaise. 
  • Cuban sandwich– Ham, roast pork, pickles, Swiss cheese, and mild mustard. 
  • Tuna sandwich– Canned tuna, mayonnaise, salt, pepper, and chopped celery. 
  • Roast beef sandwich– Rare roast beef, sliced tomatoes, and hot mustard. 

Storing sandwiches

  • To store: You can store your sandwiches in the refrigerator for up to 2 days (48 hours). I recommend you keep them untoasted and place them in a sandwich press just before enjoying it. Sandwiches are best enjoyed fresh, so make them in the morning and have them ready to eat at lunchtime!

  1. I’m ;loving your recipes and I’m excited about trying the keto macaroni and cheeseburger recipes. How are you arriving at your net carb number? The macaroni says it has 26 carbs and 13 grams of fiber. Can you tell me what I’m missing, please?
