How to Make Vegan Seitan Reuben Sandwich

Paul loves a great Reuben sandwich, so I made a vegan Reuben with seitan instead of tempeh. Since he loves my Vegan Tempeh Reuben, I figured I should give it a shot with seitan this time. It's all about variety at my house, and the more I can convince the people in my house to eat plant-based, the healthier we will all be. 

And, the true beauty of a vegan Reuben is the combination of the Vegan Thousand Island Dressing, the sauerkraut, the crunchy toasted bread, and of course, the seitan.

What is seitan?

Wheat gluten is a food made from gluten, the main protein of wheat. It is made by washing wheat flour dough with water until all the starch granules have been removed, leaving the sticky insoluble gluten as an elastic mass, cooked before being eaten.

Seitan has a mild flavor on its own but can take on many more flavors from different recipes. So, for this vegan Reuben, the marinade gives the seitan its district corn beef flavor. 

But be advised, seitan contains gluten, so if you are gluten-free, this recipe is not for you. 

How to make seitan into corn beef for a vegan Reuben 

As with most food, it's all about the marinade. And, you won't believe the crazy combination of ingredients that makes the perfect marinade for corn beef. 

Once the seitan recipe is made, slice it thin, and then it soaks in a special marinade for 1-2 days. Yes, I said 1-2 days; the longer it marinates, the more it absorbs the maximum flavor's flavors. 

What's in the marinade?

• Dill Pickle Juice
• Beet Juice
• Garlic Powder
• Dry Mustard
• Onion Powder
• Dill
• Parsley
• Black Pepper

The Vegan Thousand Island Dressing...the best sauce ever! 

• Raw cashews (soaked overnight but not necessary) or white beans if nut-free 
• Organic ketchup
• Apple cider vinegar
• Agave (you can sub maple syrup)
• Salt
• Pepper
• Water
• Diced pickles(do not blend with other ingredients; set aside.
• DO NOT blend pickles when you make the dressing.

Alternative Dressing Options:

• Dijon Mustard
• Vegan French Dressing

Making, Stacking, and Cooking a Vegan Reuben

Once the seitan is marinated, it is reheated in the oven or a skillet. Either process is simple and fairly quick. Then, add the Vegan Thousand Island Dressing and sauerkraut. 

Next, the Reuben is grilled on a medium-low skillet until the bread is crunchy. The oil-free bread does not need any oil or butter. Instead, cook it in the skillet until crispy and browned without any added butter or oils. 

And the finished product takes mere minutes to serve. I cut my sandwich in half while my husband likes his Reuben whole. 

Any way you slice it, you will love this vegan Reuben sandwich. So, give seitan a try for a cleaner alternative to fake meat.

Preparing the sandwich

1. Using your hands, squeeze all the juice from the sauerkraut and set it aside. This to avoid having a soggy sandwich.
