Potato Waffle Breakfast Burger (Plus a Breakfast Sandwich Variation)
This potato waffle breakfast burger swaps the bun for two crispy smashed potato waffles, loaded with a juicy beef patty, spicy yogurt sauce, avocado, and a runny egg. The potato waffles are shatteringly crispy on the outside and soft in the center. Genuinely one of the better things to come out of a mini waffle maker, and the breakfast sandwich variation below makes it a two-for-one recipe worth bookmarking.
At a glance: this potato waffle breakfast burger uses 2 small Yukon Gold potatoes as the bun and takes about 40 minutes total. Makes 1 burger. A breakfast sandwich variation with sausage and cheddar is included below. Chilling the potatoes overnight gives you the crispiest result.

The Waffle Maker Rabbit Hole
There's a pattern I've noticed about myself in the kitchen. I find something that works, and then my brain genuinely does not stop until I've made every possible version of it. It happened with rice paper, where I went from one spiral to fifteen different formats before I came up for air. It happened with high-protein cheesecakes and desserts, where I was blending cottage cheese into everything for months. And it's happening right now with mini waffle makers and potatoes.
It started with the Potato Waffle Breakfast Stack with Herby Drizzle, which I made as a fun, colorful tie-dye style version. Then came the Chicken Parm Potato Breakfast Waffles, because of course that happened. Then the Crispy Breakfast Potato Waffle with Avocado, Egg and Chili Crisp because I will find any excuse to open a jar of chili crisp. And now this: a full breakfast burger where the bun is a potato waffle.
The inspiration came from a brunch habit I have when I travel. When I'm out with a big group for brunch, I love ordering fried chicken and waffles and splitting it around the table. There's something about that combination… savory, crispy, stacked, a little indulgent, that makes it super fun to eat and share with a group. This is that instinct applied to a breakfast burger. Crispy potato waffle on the bottom, juicy beef patty, spicy yogurt sauce, avocado, and a runny egg on top. Closed with a second crispy potato waffle. A proper breakfast burger that happens to be gluten free!
WHY THIS POTATO WAFFLE BREAKFAST BURGER WORKS
The Potato Waffle Is a Better Bun Than It Has Any Right to Be
A regular burger bun compresses under the weight of the fillings and gets soggy from the sauces almost immediately. A crispy smashed potato waffle doesn't. The outer crust holds its structure long enough for you to eat through the whole burger without the base falling apart. It's also thinner than a bun, which means you get more burger per bite rather than fighting through a thick bread layer to reach the filling. The waffle grooves trap the sauce and egg yolk rather than letting them run off, which is a feature, not a bug.
Chilling the Potatoes Is the Non-Negotiable Step
Freshly boiled potatoes hold significant moisture in their flesh. That moisture hits the hot waffle iron and creates steam instead of direct contact, which keeps the surface soft rather than allowing it to crisp. Refrigerating overnight draws out that moisture so the potato's surface is dry when it hits the iron. The result is a noticeably crunchier waffle with deeper golden color and better structural integrity for holding burger fillings. I learned this after several batches where the waffles were good but not great. Overnight chill is the difference.
Parmesan on the Iron Before the Potato
Sprinkling Parmesan directly onto the hot iron before adding the potato creates a cheese crust that fuses to the outside of the waffle during the cook. The cheese melts and crisps against the iron surface, adding a salty, nutty layer to the exterior that makes the waffle more flavorful as a standalone component and more structurally sound as a bun. Add cheese on top of the potato instead and it just melts off. The order matters.
The Spicy Yogurt Sauce Ties Everything Together
A standard burger sauce on a potato waffle bun would overpower the delicate potato flavor and make the whole thing feel heavy. Greek yogurt-based spicy sauce is lighter, tangier, and adds heat without the richness of a mayo-heavy sauce. It sits on the waffle surface rather than soaking into it, which keeps the base crispy through the full eating experience. If you want the full recipe for the sauce, my Creamy Garlic Dijon Yogurt Sauce is the closest version on the site and works perfectly here.
"I made this once, and now I'm thinking about it constantly. Is that normal?! The potato waffle is creamy, buttery, crispy...perfection."

Recipe
Potato Waffle Breakfast Burger
Ingredients
Equipment
Method
- Boil the Potatoes: Add potatoes to a pot of cold salted water and bring to a boil. Cook 15 to 20 minutes until fork-tender. Drain and cool completely. For best results, refrigerate overnight. If short on time, cool for at least 1 to 2 hours.
- Make the Sauce: Stir Greek yogurt, hot sauce, garlic powder, and salt together until smooth. Refrigerate until ready to use.
- Preheat and Prep the Waffle Maker: Preheat the mini waffle maker. Drizzle a small amount of olive oil onto the iron and sprinkle Parmesan directly onto the surface.
- Smash and Cook: Place one potato in the center and firmly close the lid to smash it flat. Open and check that the potato has filled all the grooves. Fill any gaps with pinched-off pieces from another potato. Close the lid and using a kitchen towel to protect your hand, press down firmly for a few seconds. Cook for 12 to 13 minutes without opening until deeply golden and crispy. Remove gently and repeat with the second potato.
- Fry the Egg: Cook the egg sunny side up in a lightly oiled skillet to your preferred doneness. Season with salt and pepper.
- Build the Burger: Place one crispy potato waffle on a plate. Spread spicy yogurt sauce generously on the waffle surface. Layer with tomato slices, fanned avocado, the cooked beef patty, slice of cheddar, and the sunny side up egg. Top with the second crispy potato waffle and serve immediately.
Notes
- For the crispiest waffles, refrigerate boiled potatoes overnight before cooking. This draws out excess moisture and dramatically improves the crunch.
- Sprinkle Parmesan directly onto the hot iron before adding the potato, not on top of it. This creates the cheese crust that holds the waffle together as a bun.
- Do not open the waffle maker before 12 minutes. Patience is key here, it takes time! 🙂
- For the breakfast sandwich variation: swap the beef patty for a breakfast sausage patty, replace the spicy yogurt sauce with a slice of melted cheddar. Build with tomato, avocado, sausage, cheddar, and a sunny side up egg between two potato waffles.
- Leftover boiled potatoes from dinner the night before work perfectly here.

On the Overnight Chill:
This is the single most impactful detail in the whole recipe. Freshly boiled potatoes hold a lot of moisture inside their flesh. That moisture creates steam when it hits the hot iron rather than allowing direct contact with the surface, which is what you need for a proper crispy crust. Refrigerating overnight draws that moisture out. I made this several times before I figured that out, wondering why the waffles were good but not quite as crispy as I wanted. The overnight chill fixed it completely. The added bonus: leftover boiled potatoes from dinner work perfectly here, so this recipe can feel like almost zero effort if you plan ahead.
On Pressing Firmly:
Use a kitchen towel to protect your hand and press the lid down with real intention for a few seconds after closing. A loose close gives you a potato that's cooked through but not properly smashed into the waffle shape. The grid pattern only forms properly when the potato is compressed completely against both iron surfaces. Any gaps in the grooves after the first smash can be filled with pinched-off pieces from the second potato before cooking.
On the Spicy Yogurt Sauce:
The ratio of yogurt to hot sauce is flexible depending on how much heat you want. Three tablespoons of yogurt to one teaspoon of hot sauce is medium heat. Double the hot sauce for something with a genuine kick. The yogurt base keeps the sauce light enough that it doesn't overpower the potato waffle underneath. My Creamy Garlic Dijon Yogurt Sauce is on the site and works as an alternative if you want something with more garlic and less heat.
Breakfast Sandwich Variation:
This is the version to make when you want something that feels more like a classic diner breakfast sandwich than a burger. Swap the beef patty for a breakfast sausage patty! Build with tomato slices, fanned avocado, sausage patty, melted cheddar, and a sunny side up egg between two crispy potato waffles. Season with salt and pepper. The sausage and cheddar combination is more familiar and slightly more approachable if you're making this for people who might be skeptical about a potato waffle bun.
On the Potato Waffle Obsession:
If you want to keep going down this rabbit hole (and I strongly recommend it), the Crispy Breakfast Potato Waffle with Avocado, Egg and Chili Crisp is the chili crisp and everything bagel seasoning version of this same base. The Chicken Parm Potato Breakfast Waffles take it in a completely different direction. And the Potato Waffle Breakfast Stack with Herby Drizzle is where this whole obsession started.
FAQs about this Potato Waffle Burger (General)
A potato waffle breakfast burger uses two crispy smashed potato waffles as the bun instead of a regular bread bun. The waffles are made by boiling small Yukon Gold potatoes until fork-tender, then smashing them directly in a mini waffle maker with a sprinkle of Parmesan and cooking until deeply golden and crispy. The fillings stack between the two waffles the same way a standard burger bun would. This version is naturally gluten free and genuinely crispier and more flavorful than any bun you'd buy.
A few reasons. A crispy potato waffle holds its structure better than a standard bun under the weight of burger fillings. The waffle grooves trap sauce and egg yolk rather than letting them run off. It's naturally gluten free with no substitutions needed. And honestly it just tastes better: the crispy, slightly cheesy exterior of the potato waffle adds a flavor and texture dimension that a plain bun can't deliver.
Yes. Cook the waffles fully, cool completely, and store in an airtight container in the fridge for up to 3 days. Reheat in the oven at 375°F for 5 to 8 minutes or in the air fryer at 350°F for 3 to 4 minutes before building the burger. Do not microwave them since the moisture will soften the crispy exterior. Build the burger fresh rather than assembling ahead.
The breakfast sandwich version swaps the beef patty for a breakfast sausage patty and replaces the spicy yogurt sauce with a slice of melted cheddar. The build is otherwise identical: tomato, avocado, sausage, cheddar, and a sunny side up egg between two crispy potato waffles. It's a slightly more classic, diner-style breakfast sandwich compared to the burger version and is worth making as a variation once you've tried the original.
Yes. The potato waffles use no flour of any kind. The Parmesan, Greek yogurt sauce, and all toppings in this recipe are naturally gluten free as written. If you're cooking for someone with celiac disease, check that your hot sauce and any seasoning blends are certified gluten free since some brands include additives that contain gluten.
FAQs about this Potato Waffle Burger (Variations & Tips)
Yukon Gold is the best choice because of its naturally buttery, smooth texture and medium starch content. Russet potatoes have higher starch and can work but tend to be drier and crumble slightly more during the smash. Red potatoes are lower starch and give you a slightly firmer, less fluffy interior. Any small-to-medium potato works in a pinch. Avoid very large potatoes since they won't fit properly in a mini waffle maker.
The potato waffle bun handles any breakfast filling well. Bacon and a fried egg with hot sauce is a simple version. Smoked salmon with cream cheese and capers makes it more of a brunch situation. Crispy fried chicken between two potato waffles is essentially a homage to fried chicken and waffles in burger format, which is genuinely worth trying. Keep wet or saucy fillings controlled so the waffle base stays crispy through eating.

Do you have a suggested weight for the potato? They come in so many sizes - it’s hard to judge what’s considered medium or small. Thank you!
Hi Deb, I like to keep things simple over here. I aim for a potato that fits in the palm of your hand. The main goal here is a potato that works well in the waffle maker. Typically I use potatoes that are about the size 2 golf balls...that said, it's a rough estimate...the waffle maker is forgiving, so use what you have!
I love using my waffle iron for all kinds of things. The tip to cook, cool and then put in waffle iron with the cheese first - AMAZING. I tried with with both russet potato and a white japanese sweet potato.
