A quick and easy low-carb tuna melt made with chaffles (cheese and egg waffles) for a crispy outside and gooey inside, perfect for keto-friendly lunches or light dinners.

  • Total Time: 13-20 minutes
  • Yield: Makes 2 chaffles (servings) 1x

Ingredients

Scale
  • 1/2 cup shredded mozzarella cheese
  • 1 package tuna (packed in water or oil, drained very well)
  • 1 large egg
  • 1 pinch of salt (to taste)
  • (Optional) 1 teaspoon shredded cheese for extra crispiness

Instructions

  1. Preheat a mini waffle maker until very hot.
  2. Drain the tuna thoroughly and pat dry with paper towels.
  3. Crack the egg into a small bowl and whisk until yolk and whites are fully blended.
  4. Add the drained tuna, shredded mozzarella, and a pinch of salt to the egg and stir until evenly combined.
  5. (Optional) Sprinkle about 1 teaspoon of shredded cheese onto the hot waffle maker for extra crispiness and cook for ~30 seconds.
  6. Spoon half of the tuna mixture onto the waffle maker.
  7. Gently close the waffle maker lid and cook for at least 4 minutes, or until the chaffle is set and golden brown.
  8. Carefully remove the cooked chaffle from the waffle maker.
  9. Repeat the sprinkling (if using), spooning, closing, and cooking steps with the remaining mixture.
  10. Let cooked chaffles rest for 1–2 minutes to allow the cheese to set before serving.

Notes

Preheat the waffle maker thoroughly for the best crispy outside and tender inside., Drain tuna very well to prevent sogginess., Cook on medium heat to avoid burning outside and undercooked inside., Resting chaffles after cooking helps cheese set and preserves crunch., Leftover chaffles store well in an airtight container in the fridge for up to 2 days but may lose some crispiness., Reheat leftovers in a toaster or air fryer to regain crispiness; avoid microwaving to prevent sogginess., Tuna filling can be made ahead and stored in the fridge for up to 24 hours., Serve with light sides such as mixed green salad with vinaigrette, dill pickles, vinegar-based coleslaw, or tomato soup for a balanced meal.
