Whether you’re deep into the keto lifestyle or just craving a seriously satisfying meal, this Cheesy Bacon Chaffle Sandwich is about to become your new obsession.
Ingredients
• For the Chaffles (Makes 2)
• Shredded Cheddar Cheese – 1 cup / 113g (4 oz)
• Full-Fat Sour Cream – 3 tbsp / 45g (1.59 oz)
• For the Sandwich Filling
• American Cheese – 2 slices
• Bacon – 4 slices, cooked crispy
• Sour Cream – 2 tbsp / 30g (1.06 oz), for spreading
Instructions
1. Preheat your mini waffle maker until it’s hot. Lightly grease it with butter or a non-stick spray.
2. In a small bowl, thoroughly combine the 1 cup (240 ml) of shredded cheddar cheese and 3 tablespoons of sour cream. The mixture will be thick.
3. Spoon half of the cheese mixture onto the center of the hot waffle maker. Close the lid and cook for 3-5 minutes, or until the chaffle is golden brown and crispy. Carefully remove and set aside. Repeat with the remaining mixture to make a second chaffle.
4. While the chaffles cook, fry the bacon slices in a skillet over medium heat until your desired crispiness is reached. Transfer to a paper towel-lined plate to drain excess grease.
5. Assemble your sandwich by spreading 2 tablespoons (30 ml / 1 fl oz) of sour cream on the inside of one chaffle. Layer with the 2 slices of American cheese and the 4 slices of crispy bacon. Top with the second chaffle and enjoy immediately.

Pro Tips
• Pro-Tips for the Perfect Chaffle Sandwich
• For the crispiest chaffles, let them cool for a minute on a wire rack after removing them from the waffle maker. This prevents them from steaming and becoming soft.
• Don’t overfill the waffle maker. The cheese will spread as it melts, so a modest scoop in the center is all you need.
• Feel free to add a pinch of garlic powder or smoked paprika to the chaffle mixture for an extra layer of flavor.
• Chaffles can be made ahead of time and stored in the refrigerator for up to 3 days. Reheat them in a toaster or air fryer to bring back their crispiness before assembling your sandwich.
FAQ
Q: How do I make my chaffles extra crispy
A: For the crispiest chaffles, let them cool for a minute on a wire rack after taking them out of the waffle maker. This allows steam to escape and prevents them from becoming soft.
Q: Can I make chaffles ahead of time
A: Yes, you can make the chaffles in advance and store them in the refrigerator for up to 3 days. To restore their crispiness, simply reheat them in a toaster or an air fryer before assembling your sandwich.
Q: Is this chaffle sandwich recipe gluten-free

Pro Tips
- Let the finished chaffles cool for a minute on a wire rack before assembling — otherwise they steam and go soft under the warm fillings.
- The batter is nothing but shredded cheddar and sour cream; a pinch of garlic powder or smoked paprika stirred in adds an extra layer of flavor.
- Do not overfill the waffle maker — the cheese spreads as it melts, so a modest scoop in the center of the plates is all you need.
- Fry the bacon until properly crispy so it stays distinct against the soft American cheese instead of blending into it.
- The chaffles can be made ahead and stored in the refrigerator for up to 3 days; reheat them in a toaster or air fryer before assembling.
Frequently Asked Questions
Is this cheesy bacon chaffle sandwich keto and gluten-free?
Yes to both — the 'bread' is cheddar and sour cream chaffles with no flour at all, and each sandwich has 6 g of carbs with 42 g of protein.
Can I make the chaffles ahead of time?
Yes, up to 3 days in the refrigerator. Reheat them in a toaster or air fryer first so they are crisp again before you build the sandwich.
Why did my chaffles turn out soft?
They most likely steamed after cooking or were overfilled. Rest them on a wire rack for a minute and keep the cheese scoop modest on the iron.
Do I have to use sour cream in the batter?
It is one of only two batter ingredients — the sour cream is what makes these chaffles tender inside while the cheddar crisps outside, so it is worth keeping.
