Keto Breakfast Sandwich

Rich in flavors, filling, comforting, and just delicious – this keto breakfast sandwich is one of my favorite keto recipes. It’s high in protein, low in carbs, gluten-free, dairy-free, Paleo, and Whole30 diet-friendly.

Who doesn’t love a good sandwich?

There is nothing saying that following a keto diet means you need to give up sandwiches. In fact, it’s quite easy to make a sandwich keto-friendly.

Sandwiches are fun to eat and are a great way to mix and match different ingredients. This keto-friendly version is low carb and bread-free. And trust me, you won’t miss the bread!

There is a ton of flavor (and nutrition) packed into it.

The best part about using beef patties is that it packs on the protein. So, each sandwich ends up having 43 grams of protein.

How to Make Keto Breakfast Sandwich

Step 1. First, make sure you have allowed time for the patties to thaw if you are using frozen ones.

We’ll start by placing your beef patties between two sheets of plastic wrap or parchment paper. Roll each patty out with a rolling pan or plastic wrap roll itself.

You want the patties to end up thinner and wider than their original shape. This will help the patties stay together after they are cooked.

Step 2. Heat a non-stick or cast-iron skillet on medium-high. Add some olive oil or cooking spray so that the beef patties do not stick to the pan.

Make sure that the pan is nice and hot before placing the beef patties in. A hot pan will create crispy edges and prevent them from sticking.

Step 3. Cook each patty for about 2-3 minutes on each side. Also, make sure to season with salt and pepper.

Place the beef patties on a paper towel when they are done cooking. Gently use the towel to dab off any excess fat from the patties.

Step 4. Start with mashing the avocado in a small bowl using a fork. Then, spread half of the avocado onto one side of one of the beef patties.

Step 5. Now it’s time to fry the egg. You can use the same skillet if you like. Heat the skillet and add more cooking oil, if needed.

Crack the egg directly into the skillet. Fry the egg to your cooking preference. Make sure to salt and pepper. Frying the egg so that the yolk is completely cooked will keep your sandwich mess-free.

Step 6. Once cooked, remove the egg from the skillet with a spatula. Place the egg on top of the avocado spread on the beef patty.

Add the pickled cucumbers on top of the egg. Drizzle the mustard over the pickled cucumbers. Top the mustard with the lettuce leaves.

Then, spread the remaining avocado on half of the other beef patty. Place the beef patty, avocado side down, on the mustard.

Step 7. Now you have your sandwich!  To serve, just slice the sandwich in half and enjoy.

What Goes Good with a Breakfast Sandwich?

Keep it light by serving it alongside some tossed salad greens. Sautéed green vegetables are also a great low carb side option.

Sugar-free bacon and vegetable hash are also great breakfast options. However, do make sure you aren’t using starchy potatoes to keep a hash keto-friendly.

Sautéing turnips, brussels sprouts, and other green vegetables are a great combination to try as well. So, feel free to get creative!
