The Reuben variation feels especially indulgent. It channels classic deli comfort while staying true to keto goals. That balance is powerful. You’re not chasing substitutions — you’re building something that stands on its own merit.

And once you taste that buttery crunch? Game over.

Step-by-step — How to make it

Let’s keep this tight and actionable.

Step 1 — Build the chaffle batter
Mix egg, mozzarella, almond flour, and caraway until fully combined. You want a thick, spoonable batter.

Step 2 — Cook the chaffles
Divide batter. Spread into a hot mini waffle maker. Cook until deeply golden and crisp. Don’t rush this — crispy chaffles equal structural integrity.

Step 3 — Mix the sauce
Combine mayo, diced pickles, and sugar-free ketchup. Stir until smooth.

Step 4 — Layer the sandwich
Spread sauce on one chaffle. Add corned beef, cheese, then sauerkraut.

Step 5 — Crisp the sandwich
Secure with toothpicks or skewers. Butter the outside lightly and air fry until golden and melty.

You now hold a keto sandwich masterpiece.

Pro tips for perfect results

These elevate the sandwich from good to elite:

• Secure before cooking — fillings shift when hot
• Butter the exterior — enhances browning and crunch
• Cook chaffles fully — undercooked equals soggy sandwich
• Drain sauerkraut — excess moisture kills crispness

FYI: texture makes or breaks this sandwich. Respect the crunch.

Variations to try

Once you nail the base, experimentation becomes irresistible.

• Spicy version — add mustard or jalapeños
• Carnivore twist — skip kraut, double meat
• Cheese swap — smoked gouda or sharp cheddar
• Carnivore Chaffle Recipes Easy style — meat-forward filling

Chaffles open the door to endless Chaffle Sandwich Ideas. Creativity encouraged.

Big sandwich? Perfect. Leftovers behave well.

Store: airtight container, refrigerated
