Dietary Insights
Nutritional values below are estimates calculated using USDA FoodData Central averages for each ingredient. These are intended as a guideline; exact totals will vary by brand and portion sizes.
Per serving (assuming 6 servings total):
- Calories: ~262 kcal
- Protein: ~17 g
- Total Carbohydrates: ~1.7 g
- Dietary Fiber: ~0.7 g
- Net Carbs: ~1.0 g
- Total Fat: ~20.6 g
- Sodium: ~600 mg
Notes:
- Carbohydrates are very low because the “wrapper” is baked cheese instead of bread — making these ideal for keto and low-carb diets.
- Sodium is moderate-to-high primarily from corned beef and sauerkraut; if you’re monitoring sodium, look for low-sodium corned beef or rinse/squeeze sauerkraut to reduce salt. For sodium guidance, trusted sources like the American Heart Association recommend monitoring daily intake.

Method & Process
Ingredients
- 2 cups shredded Swiss cheese (about 8 oz / 224 g)
- 8 oz (about 227 g) thinly sliced corned beef
- 1 cup well-drained sauerkraut (about 140 g), squeezed of excess liquid
- 3 tablespoons yellow or Dijon mustard (adjust to taste)
- 1 tablespoon olive oil or butter (for a skillet; optional, just to warm fillings)
- Freshly ground black pepper, to taste
- Toothpicks for securing (optional)
Optional ingredients and substitutions:
- Use cheddar or Gruyère in place of Swiss for different flavor notes.
- For lower sodium, choose reduced-sodium corned beef or rinse and press sauerkraut.
- Add a sprinkle of caraway seeds for authentic rye-like notes.
- Swap mustard for a keto-friendly Thousand Island made with sugar-free ketchup and mayo for a classic Reuben profile.
- For dairy-free, see variations below (note: the crisp “wrapper” will change).
Step-by-step instructions
- Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper.
- In a skillet, heat olive oil or butter over medium heat and briefly warm the corned beef (30–60 seconds) to take the chill off; remove and set aside. This step is optional but helps meld flavors.
- Place shredded cheese in small 2–3 tablespoon mounds on the parchment-lined baking sheet, spreading each mound into a thin circle about 2–3 inches wide; leave space between circles to allow spreading.
- Bake the cheese circles in the oven until melted and bubbly and the edges turn golden-brown, about 5–7 minutes. Watch closely after 5 minutes to avoid burning.
- Remove from the oven and let the cheese crisps cool 1–2 minutes on the baking sheet — they’ll firm up but remain pliable for assembling.
- Once cooled slightly, carefully lift each cheese crisp (use a thin spatula) and place a slice of warmed corned beef, a spoonful of well-drained sauerkraut, and a dab (about 1/2 teaspoon) of mustard on each crisp.
- Roll each crisp gently from one edge to the other to form a roll-up and secure with a toothpick if needed. Work quickly: filling warm cheese while it’s still slightly pliable gives the best shape.
- Serve warm and enjoy your Keto Crispy Reuben Roll-Ups!
Practical tips:
- Don’t overbake the cheese: remove when edges are golden but center still slightly pliable so it can wrap without cracking.
- Drain and press sauerkraut in a small sieve or between paper towels to avoid soggy crisps.
- If a crisp cools and becomes brittle, reheat for 10–15 seconds in the microwave or return to a 300°F oven for a minute to regain flexibility (be careful—cheese melts fast).
- Make cheese rounds uniform in size for consistent baking and presentation.
Serve It Up
- Appetizer platter: arrange roll-ups on a board with fresh pickle spears, extra mustard, and a few grainy olives for variety.
- Brunch bite: serve alongside scrambled eggs or a small leafy salad dressed with lemon vinaigrette.
- Snack with a hot drink: these pair surprisingly well with black coffee or a robust tea in the morning.
- Sandwich-style pairing: top a couple of roll-ups on big lettuce leaves to make a low-carb “wrap” that’s easy to hold.
Also consider trying a similar handheld comfort idea with these crispy French dip tortilla roll-ups if you’re assembling a mixed platter—different flavors and textures keep a grazing table exciting.
Keeping it Fresh
- Room temperature: Do not leave roll-ups out longer than 2 hours (per USDA food safety guidelines) because they contain meat and dairy.
- Refrigeration: Store in an airtight container in the refrigerator for up to 3–4 days. Place parchment layers between layers to prevent sticking.
- Freezer: You can freeze assembled roll-ups, wrapped well in plastic and stored in a freezer-safe container, for up to 1 month. Reheat from frozen in a 325°F oven until warmed through (10–15 minutes); note the cheese crisp texture can soften after freezing.
- Reheating: For best texture, reheat in a toaster oven or conventional oven on a baking sheet at 300–325°F for 5–8 minutes rather than microwaving, which will make the cheese chewy.
Chef’s Advice
- Cheese selection matters: choose a cheese that melts smoothly—Swiss, Gruyère, or a medium-aged cheddar create the best pliable crisps with clean flavor.
- Size and thickness rule: spread cheese thinly and evenly; thick mounds won’t crisp properly and will stay gummy in the center.
- Work warm: assemble while the crisps are still slightly warm and flexible; once fully cooled they will crack when rolled.
- Textural contrast: squeeze sauerkraut dry — too much liquid is the most common cause of limp crisps.
- Batch baking: bake multiple sheets, rotating position in the oven for even color; each oven heats differently, so test one round first to find your ideal bake time.
Fun Flavor Ideas
- Spicy Reuben: add a sliver of pickled jalapeño and swap mustard for a smear of chipotle mayo (keto-friendly) for a smoky heat.
- Vegetarian twist: replace corned beef with pan-seared tempeh or a thin slice of marinated and smoked seitan. Use vegan cheese suitable for melting, but expect a different texture.
- Smoked Gouda & Dijon: use smoked Gouda for the wrapper and a touch of Dijon and caramelized onion in place of sauerkraut for a richer, sweeter profile.
- Mediterranean Reuben: use halloumi crisps, swap sauerkraut for pickled red cabbage, and add a lemony mustard vinaigrette for bright notes.
Recipe Q&A
Q: Can I make these ahead of time?
A: Yes — prepare cheese crisps and fillings separately. Store crisps in an airtight container at room temp or fridge (short term) and assemble just before serving for best texture.
Q: My cheese crisps cracked when I rolled them. What went wrong?
A: They likely cooled too much or were baked too thinly/thickly. Try rolling while still slightly warm and ensure an even thin spread.
Q: Are these safe to eat if left out at a party?
A: Follow food safety: hot or cold perishable foods should not be left out more than 2 hours. Keep them on small plates and replenish from the fridge as needed.
Q: Can I use pre-shredded cheese?
A: Yes, but shredded-from-block cheese often melts better because pre-shredded varieties contain anti-caking agents that can change the melt and crisp texture.
Q: How can I reduce sodium?
A: Rinse and squeeze sauerkraut, choose lower-sodium corned beef, and reduce added mustard. Also consider pairing with low-sodium sides.
