You catch the smell through the steam vent and suddenly you are starving. That little hiss from the valve tells you the dinner’s coming together, and your stomach starts kinda rumbling real loud. It’s funny how a simple thing like the broth depth can get you all excited even before the meal is ready.

You notice the steam swirling around and the kitchen filling with those sharp sauerkraut smells mixed with the tangy corned beef scent. That quiet pressure build inside the cooker is like waiting for a surprise, and you just wanna get to the tender pull moment already.
When the natural release finally happens and you hear that last sigh of steam escaping, you just know it’s gonna be the best dang sandwich you ever had. The kitchen feels warm and inviting, and your mouth waters as you imagine biting into the crispy outside and the juicy inside.
Why This Recipe Works Every Single Time
- Using chaffles as the bread keeps carbs way low but still gives you that crunch you crave.
- The dressing with mayo, keto ketchup, and dill pickles adds a tangy creaminess that wakes up every bite.
- Corned beef slices get tender and juicy thanks to the pressure cooker’s perfect broth depth and heat control.
- Sauerkraut adds just the right zing and moisture without making it soggy.
- Swiss cheese melts into all the flavors for a gooey, cheesy hug inside each bite.
- Finishing the sandwich in a skillet helps get a golden crust that seals all the goodness in place.
Your Simple Ingredient Checklist
- 3 tablespoons mayonnaise – gives your sandwich a smooth, creamy base for the dressing.
- 1 tablespoon keto ketchup or any keto-friendly ketchup – adds that classic Reuben sweetness without the sugar hit.
- 2 tablespoons minced dill pickles – these little guys bring texture and tang for your dressing.
- 4 chaffles made with 1 teaspoon crushed caraway seeds – they mimic rye bread flavor with zero carbs and perfect crunch.
- ¼ pound corned beef, sliced thin – the star protein that’s moist and tender after pressure cooking.
- 1 cup sauerkraut – adds that signature tang and keeps the flavors bright.
- 2 ounces Swiss cheese – melts so nice inside every roll-up.
- 2 tablespoons butter – for the skillet finish to golden up your sandwich rolls real good.
- Optional: extra caraway seeds for sprinkling – if you wanna amp up that rye bread vibe even more.

How It All Comes Together Step by Step
- Start by mixing mayonnaise, keto ketchup, and minced dill pickles in a small bowl. This dressing gives your sandwich a fun tangy cream layer.
- Lay your chaffles flat and spread a good layer of that dressing over each one. You don’t gotta be too neat here, just get it all covered.
- Now, top each with slices of corned beef, a scoop of sauerkraut, and Swiss cheese evenly. You want each bite filled real good.
- Roll each chaffle up tightly so all that yummy filling stays inside while you cook.
- Heat butter in a skillet over medium heat. When it’s melted and hot, carefully place the roll-ups seam-side down to seal them.
- Cook each side about 3 to 4 minutes until they’re golden brown and the cheese is all melted inside. Keep an ear out for that little valve hiss from your pressure cooker to know the heat is just right.

Time Savers That Actually Work
- Make your chaffles ahead and stash ’em in the fridge so you can whip this sandwich up in no time.
- Grab pre-sliced corned beef from your deli to avoid extra slicing work.
- Use a jarred sauerkraut that’s already drained so you don’t get soggy bread.
- Mix your dressing ingredients while the pressure cooker does its job, multitasking like a pro.
- Heat your skillet early so it’s ready to go as soon as you’re done with the roll-ups.
When You Finally Get to Eat
You pick up that warm roll-up and feel the crispy outside under your fingers. The smell alone gets your mouth watering for that first bite. You sense the soft melted Swiss cheese oozing just a little as you bite in.
The tangy dressing mixes with sauerkraut and corned beef perfectly, hitting your taste buds with every chew. You notice the subtle caraway seed crunch inside the chaffle adding an unexpected little zip. It’s kinda like eating a fancy version of your favorite old-school sandwich, but way better.
Each bite feels full of flavor and texture — crunchy, creamy, tangy, and savory all in one. You realize cooking this sandwich in your pressure cooker and skillet made it tender and golden like you wanted, and dang it, you nailed it today.
Smart Storage That Actually Works
- If you got leftovers, wrap ’em tight in parchment paper or foil to keep the roll-ups from drying out in the fridge.
- Store in an airtight container for up to three days. When reheating, do it in the skillet to get back that crispy outside instead of the microwave mush.
- If you wanna keep them longer, freeze individually wrapped sandwiches. Thaw overnight in the fridge and then reheat in a skillet or toaster oven for best results.
