Can I use whole eggs instead of egg whites in the chaffle recipe?
Yes, you can use whole eggs, but the texture will change slightly. The chaffle will be a bit richer and denser.
What can I substitute for almond flour if I have a nut allergy?
If you have a nut allergy, you can try using coconut flour, but keep in mind that you'll need to adjust the amount since coconut flour is more absorbent. Start with about half the amount and add more as needed.
How do I store leftover chaffles?
You can store leftover chaffles in an airtight container in the refrigerator for up to 3 days. To reheat, pop them in the toaster or an air fryer for a crispy finish!
Can I freeze the chaffles for later use?
Absolutely! You can freeze the chaffles by placing them in a single layer on a baking sheet until frozen, then transferring them to a freezer bag. They can last up to 2 months in the freezer.
What are some low-carb fillings I can use for my chaffle sandwich?
Some tasty fillings include sliced turkey or chicken, cheese, avocado, spinach, and mustard. Just check the carb counts on any condiments you use!
I've tried a handful of chaffle sandwich recipes and they all taste like egg. This one doesn't. The mayonnaise in the batter is doing something to the texture that actually reads as bread.
That's exactly it. The mayo coats everything differently than oil would. Less eggy, more structured. It was the swap that finally made this one click.
Are these freezable? I mean, do they keep their consistency/texture? Sorry if this was already asked, but I didn’t see it.
Yes, you can freeze them. I just toast them up or air fry them to get rid of moisture.
Im new to keto, only 2 weeks in, and this is an absolute revelation!
Thank you so much, it's actually like eating bread and you certainly don't feel like you're missing out.
Can't wait to try your other recipes, thank you again, especially for sharing your knowledge and experience 🥳
What if you use the whole egg? What's the result like?
You can use a whole egg but it will change the color of the chaffle.
I love this recipe! I quadruple the recipe and cook all of them at one time. I keep them in the fridge and toast them for Eggs Benedict, grill them in a Philly cheese steak sandwich or a mid-afternoon cheese toast snack. Thanks for developing the recipe and sharing it.
are we supposed to spray the waffle plates first? i just created a disaster....LOL
No, you shouldn't have to if your waffle maker is non-stick. You may have to let them cook longer so that the outside sets. But you could always spray it to be on the safe side.
I just made my first one. I substituted coconut flour, I used 1/4 tblsp. Then added more, so about 1/2 a tblsp. Its amazing! I love it!
I tried this chaffle yesterday and made a BLT. I LOVED every BITE! Bread? Who needs it!! lol
This was my favorite chaffle by far to date. I've only been on keto for a month, but have tried numerous other chaffle recipes and for me, they're too heavy and greasy. I did take your suggestion and used egg whites instead of the whole egg. Whisked before starting each new chaffle in my little Dash machine to keep them fluffy. These were excellent! Made some to freeze, toasted two for lunch with a wonderful, crunchy base for a tuna sandwich. Can't wait to try with a burger! Many thanks :)
This looks delicious. I don't know if you knew it, but this recipe and photo are in the book Keto Chaffle Recipes Cookbook. I looked inside the book online to see if it would be worth the cost. Many of the recipes seemed to be copied from the internet (although strangely reworded to seem like they were written by a bot at times) so I searched for matching ones and yours came up here. I don’t know if you gave permission for it to be used but I thought I’d give you a heads up.
I wasn't aware of that. That's too bad people have to scrape recipes from other bloggers just to make a buck. Unfortunately, there's not much bloggers can do to stop it. Have heard of many stories of people making e-books with other peoples recipes & content and selling them on Amazon under a fake name. They will do it until they get shut down, then do it again under a different name. Thanks for bringing it to my attention. I will let Amazon know.
I really wanted to love this recipe, but unless you are allergic to cheese, I’d stick to a regular chaffel recipe. This was like eating a soggy egg white omelet.
PS I love many of your recipes,
I'm sorry, I wonder what happened? Maybe it didn't cook long enough? It's supposed to be spongy like bread.
I don’t have this type of waffle maker , can I use any type at all ?
Yes, any waffle maker will work. Even a Belgium waffle maker :)
Can you toast this to make it crispy?
Yes! You can toast them.
tried the wonderbread chaffle tonight and it was runny..any suggestions??
The chaffle batter might seem running but the chaffle cooks and puffs up when you cook it in the waffle maker. This chaffle will be soft like white bread and not crispy like a traditional waffle.
I've had the same experience with batter being very runny. I've found it helps to let the batter sit for
a few minutes and let the almond flour hydrate to thicken it a bit. Hope that helps!
My family ate out and I was able to make this “bread” by time hubby (aka My Uber eats) was back with food, so I had a DELICIOUS low carb double cheese burger....and I’m a happy FULL wife! :) Thank you Annie!! :)
Wonderful Jacqueline! I'm glad this worked as a quick substitute for bread. That's what we do too! Double cheeseburger has me drooling now! :)
