1.Can I use Thousand Island dressing instead of Russian dressing for this Reuben?
▾
You absolutely can in a pinch, but note that classic Russian dressing is tangier, spicier, and has a hint of horseradish, while Thousand Island is sweeter with pickle relish. To get closer to authentic Reuben flavor, stir ¼ teaspoon of prepared horseradish and a tiny pinch of smoked paprika into your Thousand Island before spreading.
2.How do I keep my grilled rye bread from getting soggy from the sauerkraut?
▾
Sogginess is the number one Reuben mishap! First, squeeze your sauerkraut really well over the sink—press it with paper towels until no excess brine drips out. Second, spread a thin layer of softened butter on the bread’s outer side, and a thin dressing layer on the inner bread to create a moisture barrier.
3.Do I need to use seeded rye bread, or can I use plain rye?
▾
Seeded rye adds that classic earthy, nutty crunch and deep rye flavor that makes a deli Reuben feel authentic, but plain rye works totally fine if that’s what you have on hand. For the best texture, pick a thick-cut loaf (about ½-inch slices) so it holds up to hearty fillings without tearing as you grill.
4.What’s the best way to heat the corned beef before assembling the sandwich?
▾
Don’t pile cold corned beef straight into the sandwich, because it won’t heat through evenly by the time the bread is toasty. Warm thin slices in a dry skillet over medium heat for 30 to 45 seconds, just until steamy, right before assembling. This also helps the Swiss cheese melt smoothly against the warm meat.
5.Can I make this Reuben with pastrami instead of corned beef?
▾
Technically a pastrami-swapped Reuben is called a Rachel, but there’s no recipe rule police stopping you! Pastrami has a smokier, peppery profile compared to corned beef’s brinier, milder flavor, so it makes a delicious twist. Stick to thinly sliced, deli-style cuts so it stacks easily and bites cleanly without pulling out.
6.How much butter should I use to grill the bread for the perfect crispy crust?
▾
Use about 1 teaspoon of softened, unsalted butter per outer slice of bread, spread all the way to the edges for even crisping. Skip melted butter here—softened butter spreads evenly without soaking too deep into the bread, so you get a golden, shatteringly crisp crust instead of a greasy, soggy slice.
7.What heat setting should I use to grill the sandwich so the cheese melts before the bread burns?
▾
Stick to medium-low heat, around 325°F if you’re using an electric griddle. Higher heat will char the rye before the Swiss has time to melt all the way and the fillings warm through. Cook 3 to 4 minutes per side, pressing gently with a spatula once after flipping, until bread is golden and cheese oozes at the edges.
8.Can I use low-moisture mozzarella instead of Swiss cheese if I don’t have Swiss?
▾
I don’t recommend it! Swiss has that signature nutty, slightly sweet flavor that cuts through the tang of sauerkraut and richness of the dressing, and it melts into that perfect stretchy, creamy layer. If you need a swap, go for Gruyère or Emmental, which have a similar flavor and melt quality, rather than mild mozzarella.
9.How much sauerkraut should I put per sandwich for the right flavor balance?
▾
Aim for about ¼ cup of well-drained sauerkraut per sandwich, spread in an even layer across one slice of bread. Too much sauerkraut (even well-drained) will make the sandwich heavy and overly tangy, while too little gets lost against the corned beef and cheese. Spread it flat, not mounded, for even flavor in every bite.
10.Can I make these sandwiches ahead of time for a party or picnic?
▾
Reubens are best fresh off the griddle, but you can prep all components ahead to cut down on day-of work. Drain the sauerkraut, portion your dressing, and slice your bread and cheese ahead of time, then warm the corned beef right before assembling and grilling. Assembled, ungrilled sandwiches get soggy if left to sit longer than 10 minutes.
11.Do I need a panini press to make a great grilled Reuben?
▾
Not at all! A regular cast iron skillet or nonstick frying pan works perfectly. If you want that pressed, deli-style flat finish, set a heavy second skillet (or a foil-wrapped brick) on top of the sandwich as it cooks on the first side, then flip and repeat. You’ll get the same crispy, compact sandwich without special equipment.
12.Why does my corned beef pull out of the sandwich when I take a bite?
▾
That happens when your corned beef slices are too thick, or piled in a big loose clump instead of stacked neatly. Stick to paper-thin deli-sliced corned beef, and shingle the slices in even, overlapping layers across the bread. Thin slices stick together better as the cheese melts, so you get a clean bite without meat sliding out.
13.Is there a non-dairy swap for the Swiss cheese that works well here?
▾
Yes! Look for a non-dairy Swiss-style melting cheese, usually made from a coconut or oat base, that’s formulated to melt smoothly rather than stay firm. Avoid crumbly non-dairy cheeses, because they won’t create that creamy, binding layer between bread and fillings. Pair with non-dairy butter and vegan Russian dressing for a fully plant-based version.
14.Should I rinse my sauerkraut before using it to cut down on tang?
▾
That’s totally up to your taste preference! If you love that bright, briny tang, just drain it well and use it as-is. If you prefer a milder, less sour flavor, give the sauerkraut a quick rinse under cold water after draining, then press it completely dry with paper towels before adding it to the sandwich. Never skip the drying step, even if you rinse.
15.What sides pair best with a classic grilled Reuben?
▾
Classic deli sides work perfectly here! Dill pickle spears are non-negotiable for that extra briny kick, and crispy ridged potato chips, creamy coleslaw, or a cup of tomato soup all make fantastic pairings. Skip heavy, overly rich sides that compete with the sandwich—light, briny, or crisp options balance the flavors best.
16.Can I use homemade corned beef instead of deli-sliced for this recipe?
▾
Homemade corned beef makes an even better Reuben, as long as you slice it correctly. Let your cooked corned beef rest for 20 minutes, then slice it against the grain as thinly as you can—ideally 1/8-inch thick or less, using a sharp slicing knife if you have one. Thick, homemade slices will be chewy and slide out, so thin slicing is key.
17.How do I reheat a leftover grilled Reuben so it doesn’t get soggy?
▾
Skip the microwave—it will turn the rye rubbery and make the fillings mushy. Reheat leftover Reubens in a dry skillet over medium-low heat for 2 to 3 minutes per side, until the bread crisps back up, the cheese re-melts, and the center is warm. You can also use a toaster oven at 350°F for 5 to 7 minutes for the same crispy result.
18.Is it okay to add extra toppings like coleslaw or pickles inside the Reuben?
▾
Of course! The classic recipe sticks to the core four fillings, but you can customize to your taste. If you add coleslaw, drain it extremely well to avoid sogginess—note that a Reuben with coleslaw instead of sauerkraut is also called a Rachel. Thinly sliced dill pickles inside add a nice extra briny kick without throwing off the sandwich’s texture.
OMG, this Reuben is an absolute game changer! Made it for our Sunday football watch party over the weekend and every single person asked for the recipe. I used extra sauerkraut like I always do, and the thousand island dressing ratio was perfect — not too drippy, not too dry. 10/10 will be making this every other week for meal prep too.
My kids LOVED these! I was worried the sauerkraut would be too tangy for my picky 8 year old, but he ate his entire sandwich in 5 minutes and asked for seconds. Super easy to throw together on a busy weeknight too, only took me 20 minutes total just like the recipe says. Win for family dinner!
SO good. I’ve tried so many Reuben recipes over the years and this is hands down the closest to the diner version I grew up eating in upstate NY. The buttered rye grilled to that perfect crispy crunch? *Chef’s kiss* I didn’t change a single thing and it came out perfect first try.
Great base recipe! I swapped the rye bread for gluten free seeded rye to fit my dietary needs, and it still turned out amazing. Only thing I’ll note is my gluten free bread got a little soggier faster than regular rye, so I’ll probably toast it a little longer next time before piling on the fillings.
Brought these to our neighborhood potluck last weekend and they were gone in 10 minutes flat! I cut them into quarters as little sliders so people could grab them easily, and people were raving about them all night. So easy to make a big batch too, I’ll definitely be pulling this recipe out for our next block party.
Total game changer for quick lunches! I prepped all the fillings on Sunday, and when I was ready to eat all I had to do was assemble and grill for 5 minutes. Tasted just as good as the sandwich I get at my local deli for half the price. Will be adding this to my regular meal rotation.
Tried this for the first time tonight! I think I had my griddle a little too hot because the first sandwich burned the rye before the cheese was fully melted, but I turned the heat down for the rest and they turned out great. Definitely a learning curve but so worth it, the flavor is incredible.
Pro tip from someone who’s made a hundred Reubens: add a tiny pinch of caraway seeds to the butter you spread on the outside of the rye. It amplifies that classic rye flavor so much, people will think you got the sandwich straight from a NYC deli. This recipe is already perfect, that little hack just takes it over the top.
