No fire pit? No problem. Learn four indoor ways to toast sugar free marshmallows, from the broiler to the microwave, plus texture tips for perfect keto s'mores.
Quick answer
To toast sugar free marshmallows indoors, use your oven's broiler set to high with the rack about 6 inches from the heat. Line a sheet pan with parchment, arrange the marshmallows with space between them, and broil for 30 to 60 seconds. Watch constantly because they brown fast. For a single serving, the microwave trick works in 10 to 15 seconds.

Why indoor toasting is different for sugar free marshmallows
Sugar free marshmallows brown faster than traditional ones because they lack the sugar that caramelizes slowly. That means your window between perfectly toasted and burnt is narrower. Stay close to the oven or microwave the entire time. Also note that sugar free marshmallows firm up quickly as they cool, so eat them within a minute or two of toasting for the best texture.
Pick your heat source: broiler, air fryer, stovetop, or microwave
The broiler gives you the closest thing to a campfire char and works for batches. An air fryer circulates hot air for even browning and is great for 4 to 6 marshmallows. A stovetop skewer over a gas flame is the most hands-on but gives you precise control. The microwave is the fastest for a single marshmallow or a quick s'more, though it softens rather than chars. Choose based on how many you're toasting and how much char you want.
Set up your toasting station
Line a sheet pan with parchment paper for the broiler or air fryer. If using the stovetop, have a metal skewer or long fork ready. For microwave, use a microwave-safe plate. Keep a pair of tongs nearby. Have your low carb s'mores components—like sugar free chocolate and a keto-friendly graham-style cookie—within reach so you can assemble immediately after toasting.
Step-by-step indoor toasting methods
- Broiler method (best for batches): Set oven to broil on high and move the rack 6 inches from the heating element. Line a sheet pan with parchment and space marshmallows 1 inch apart. Broil 30–60 seconds, watching constantly. Pull them when they reach your desired brownness. Common mistake: walking away. Sugar free marshmallows can go from golden to burnt in under 10 seconds.
- Air fryer method (even browning): Preheat air fryer to 390°F. Place marshmallows in a single layer in the basket, not touching. Air fry 2–3 minutes, shaking the basket halfway. They're done when puffed and browned. Checkpoint: if your air fryer runs hot, start checking at 90 seconds.
- Stovetop skewer method (most control): Thread a marshmallow onto a metal skewer. Hold it 2–3 inches above a medium gas flame, rotating slowly. Toast 1–2 minutes until evenly browned. For electric stoves, use a culinary torch held 3–4 inches away. Common mistake: holding too close. Keep the marshmallow moving to avoid a burnt spot.
- Microwave trick (single serving): Place one marshmallow on a microwave-safe plate. Microwave on high for 10–15 seconds. It will puff and soften but won't brown. For a quick s'more, add sugar free chocolate and a cookie, then microwave another 5 seconds to melt. Checkpoint: microwave in 5-second bursts after the first 10 seconds to avoid over-expanding.
Product facts
- Marshmallows: Extra fluffy, packed full of prebiotic fiber and sweetened with monk fruit, each sugar free marshmallow has a light vanilla flavor and is perfect for roasting, baking, melting, or just eating out of the bag. These sugar free marshmallows roast and melt just like the real thing. When they go stale, they will get denser than other products. They behave like traditional marshmallows under heat, so you can use the same toasting techniques. The density change means you should store them airtight and use them fresh for best texture.
- Blueberry Breakfast Cookies: Blueberry breakfast biscuits are fiber-rich cookies with real blueberries baked into the dough, made without wheat and sugar. These can stand in for graham crackers in a low carb s'mores build, adding a fruity tartness that balances the toasted marshmallow.
