If you’re looking for a nutrient-dense, gluten-free alternative to your standard burger bun, you just found it. These Grain-Free Sweet Potato Waffle Buns are a total game-changer. They are crispy on the outside, tender on the inside, and hold up perfectly to even the juiciest burger or breakfast sandwich.

The best part? No flour, no yeast, and no waiting for dough to rise. Just a handful of whole-food ingredients and your trusty mini waffle iron!

Ingredients for Sweet Potato Waffle Buns (Grain-Free)

Yields: 8 waffle buns (Perfect for 4 sandwiches)

  • 1 medium sweet potato (grated—regular russet potatoes work too!)

  • 2 whole eggs

  • 60g egg whites (or swap for 2 additional whole eggs)

  • 2 tsp garlic powder

  • 2 tsp onion powder

  • Salt and pepper, to taste

  • Avocado oil or olive oil spray (high-heat spray is your best friend here!)

Steps

  1. Prep the Potato: Grate your sweet potato over a large mixing bowl. Use a box grater or a food processor attachment to make quick work of it.

  2. Mix the "Batter": Add your eggs, egg whites, garlic powder, onion powder, salt, and pepper to the shredded potato. Mix thoroughly until every bit of potato is coated in the egg mixture.

  3. Preheat & Grease: Plug in your mini waffle iron and let it get hot. Once ready, apply a generous amount of avocado oil spray. Don't be shy here—the oil is what creates that golden, crispy crust and prevents sticking.

  4. The Waffle Build: Scoop a generous amount of the mixture into the iron.

    Pro-Tip: Don’t press down too hard on the lid! Let the iron sit naturally so the waffle stays thick and fluffy. The thicker waffles tend to hold up better as buns!

  5. The Patient Cook: These take a bit longer than a traditional flour waffle. Check on them every few minutes. You are looking for a dark golden-brown color and a firm structure.

  6. Remove & Cool: Gently use a fork to lift the edge and remove the waffle. It will be very hot! Let it rest for a minute to firm up before assembling your sandwich.
