Ingredients in A Vegetarian reuben
This vegetarian seitan sandwich is complete with only 6 items. You can use your favorite bread and cheese, but I definitely recommend rye/sourdough and Swiss! Complete the ‘wich with thousand islands dressing for even more flavor. YUM.
- Bread: First up, you will need 2 pieces of either rye or sourdough bread. The thickness and texture of these types of bread make them great for hot sandwich making — they don’t get as soggy!
- Butter: Next, you will need a pat of unsalted butter for spreading on the outside bread to achieve that golden crispy crust.
- Dressing: For the sauce, use 2-4 tablespoons of thousand islands dressing (depending on how much you like the stuff!)
- Cheese: Next up, 2 slices of Swiss cheese. Provolone would also work well here if that’s what you have on hand.
- Seitan: You will need 2-4 slices of your very own homemade Seitan Corned Beef.
- Sauerkraut: Last but not least, finish things off with ¼ cup of sauerkraut!
How to make a vegetarian reuben sandwich
Grab your seitan corned beef and Swiss cheese, because it’s time to dive into making this reuben! We’ll start by prepping the bread, then we’ll assemble and cook. Oh, and don’t forget a side pickle spear!
Step 1: Prep the bread
Spread the butter onto one side of each slice of bread.
Step 2: Assemble the reuben
Onto the other side of the breads, spread thousand islands dressing. Layer on half of the cheese, Seitan Corned Beef, sauerkraut, and then the remaining cheese.
Step 3: Cook the sandwich
Cook over medium heat in a large skillet or panini press until the outsides of the bread are golden brown and the cheese has melted. Alternatively, you can set the oven to broil and cook for 3 to 5 minutes. Serve immediately.
Tasty Variations
Here are some quick tips for switching things up and customizing your reuben to perfection!
- Add veggies: You can’t go wrong here. Add anything you’d like! Ideas include onions, pickle chips, peppers, and even a tomato slice.
- Swap the cheese: Swiss is classic, but pepper jack, cheddar, or provolone will work magically.
- Don’t underestimate seasonings: Garlic, chili pepper flakes, and even oregano can go a long way in adding extra flavor!
