Substitutions and Variations

Healthy and hearty, this vegan roast is sure to satisfy

Don’t be afraid to get creative with this recipe! As a vegan chef, I understand the importance of making substitutions and variations to cater to different tastes and dietary restrictions.

If you don’t have all the herbs listed, you can substitute dried rosemary or marjoram for the dried sage or thyme. You could also add some chopped fresh parsley or cilantro for added freshness.

For those who may have gluten intolerances or allergies, try using chickpea flour instead of vital wheat gluten for a gluten-free version. Substitute vegetable broth with a low-sodium option or water to make it gluten-free and reduce sodium intake.

I love experimenting by swapping the vegetables in the dish. Instead of leeks, you can use onions or shallots. If you’re not a fan of shiitakes, try crimini mushrooms, oyster mushrooms, or portobello mushrooms instead.

For a Thanksgiving twist, put a spin on your vegan turkey roast and serve your seitan wellington as the centerpiece! Add some stuffing made with chestnuts and serve with some vegan mushroom gravy on top to make it extra special!

Remember, cooking is all about fun and creativity- so don’t hesitate to get playful with this recipe!

Tips for Perfect Results

As a vegan chef, I want to share with you my tips for making the perfect Seitan Roast with Shitakes and Leeks.

1. Use a digital thermometer

When cooking seitan, it can be difficult to know when it is done. Using a digital thermometer takes the guesswork out of it. The internal temperature of your seitan should read at least 160 degrees Fahrenheit.

2. Let it cool before slicing

Once your Seitan Roast with Shitakes and Leeks is fully cooked, resist the urge to slice into it right away. Allowing it to cool for at least 10 minutes will help it hold its shape and make slicing easier.

3. Sauté the mushrooms before stuffing

To bring out the rich, meaty flavor of your shiitake mushrooms, sauté them in olive oil and garlic before stuffing the seitan. This will also help prevent any excess moisture from making your seitan soggy.

4. Roll it tightly

When wrapping your stuffed seitan in parchment paper, be sure to roll it tightly to ensure even cooking and prevent any filling from spilling out. This will also give it that classic log shape reminiscent of a traditional turkey roast.

5. Brush with vegetable broth

For added depth of flavor and moisture, brush your Seitan Roast with Shitakes and Leeks with vegetable broth before baking. This will give your roast a delicious golden crust while keeping it juicy on the inside.

Follow these tips to make a perfect Seitan Roast with Shitakes and Leeks every time!


As with any recipe, you may encounter questions while preparing the Seitan Roast with Shitakes and Leeks. Here are some frequently asked questions and their answers to help ensure a successful cooking experience.

Does seitan need to be cooked?

When it comes to cooking seitan, it’s important to keep in mind that it has already been cooked beforehand. Therefore, all that’s needed is to heat it up to match the temperature of the other components in the dish. If you opt for a moist cooking method such as simmering, this allows you to take the time to let the flavors of your dish fully infuse into the seitan. However, when using dry cooking methods like grilling, it is best to work quickly to avoid overcooking and drying out the seitan.

Is it better to steam or boil seitan?

Different cooking methods can result in varying textures when preparing seitan. For instance, boiling seitan can create a spongey and brainy texture, while frying it without prior steaming can result in a rubbery and spongey texture. On the other hand, baking seitan can make it dry and rubbery. However, steaming seitan is an efficient way to achieve a perfect meaty, juicy, chewy, yet tender texture every time.

How long should you knead seitan?

If we want a meaty texture in our seitan, we must develop strands of gluten through kneading. This can be done in about 5 minutes, which is similar to kneading bread dough.

How do you know when seitan is done?

Before beginning, keep an eye on the pot’s temperature, preventing it from boiling. Cook your steaks for around 50 minutes to 1 hour, but smaller pieces may cook faster, within 45 minutes. Tongs can help you determine when your seitan has become solid by squeezing it. Another way to make sure it’s done is to slice into the center of a piece.

Bottom Line

There you have it, folks – a recipe for a succulent and hearty seitan roast stuffed with herbed, meaty shiitakes and leeks that will satisfy even the most discerning vegan palates.

For the filling

  • 2 tablespoons olive oil
  • 6 ounces shiitake mushrooms, thinly sliced (rough ends removed)
  • 2 leeks, white and light green parts only, cut into thin half moons
  • 1/2 teaspoon salt
  • fresh black pepper
  • 3 garlic cloves, minced
  • 2 tablespoons chopped fresh thyme
  • 1/4 cup breadcrumbs
  • 1/4 cup vegetable broth
  • 1 tablespoon fresh lemon juice

For the roast

  • 3 garlic cloves
  • 3/4 cup cooked pinto beans, rinsed and drained (fresh or canned)
  • 1 1/2 cups vegetable broth
  • 3 tablespoons soy sauce
  • 2 tablespoons olive oil
  • 2 cups vital wheat gluten
  • 1/3 cup nutritional yeast
  • 1 teaspoon fennel seed, crushed
  • 1 teaspoon sweet paprika
  • 1 teaspoon dried thyme, crushed between your fingers
  • 1 teaspoon dried sage, crushed between your fingers
  • 3 dashes fresh black pepper


  • First prepare the filling:
  • Preheat a large pan, preferably cast iron, over medium heat. Saute the mushrooms and leeks in oil until soft, about 10 minutes. Add salt, pepper, garlic and thyme. Cook for about 2 more minutes, stirring often.
  • Sprinkle in the breadcrumbs and toss to coat. Cook the mixture, stirring very often, until the breadcrumbs are toasty and the mixture is relatively dry. This should take about 5 minutes, and the breadcrumbs should turn a few shades darker.
  • Drizzle in the broth and lemon juice and toss to coat until moist. If it still seems dry drizzle in a little extra olive oil. Set aside until ready to use.
  • Prepare the roast:
  • Preheat oven to 350°F In a food processor, pulse the garlic until well chopped. Add the beans, broth, olive oil and soy sauce and puree until mostly smooth (a few pieces of bean are okay, but they should be no bigger than a pea.).
  • In a large mixing bowl, mix together the wheat gluten, nutritional yeast, herbs and spices. Make a well in the center and add the bean mixture. Stir with a wooden spoon until the mixture starts coming together to form a ball of dough. Knead until everything is well incorporated.
  • Now we’re going to roll out the seitan and form the roast. Place two pieces of tin foil (about 18 inches long) horizontally in front of you. The sheet further from you should overlap the closer sheet by about 6 inches. This way you have enough foil to wrap around the whole roast.
  • On a separate surface, use your hands or a rolling pin to flatten the seitan into a roughly 12 x 10 rectangle. If any pieces rip, don’t worry about it, just use a pinch of dough from the ends to repair any holes.
  • Place the filling in the lower 1/3 of the seitan rectangle, leaving about 2 inches of space at both ends. Make sure the filling is compact, use your hands to form it into a nice, tight bundle.
  • Now roll! Roll the bottom part of the seitan up and over the filling. Keep rolling until in it’s in a log shape. Now pinch together the seam and pinch together the sides to seal. It doesn’t have to be perfect, it will snap into shape when baking.
  • Place the roll in the center of the tinfoil and roll up like a tootsie roll, making sure the ends are tightly wrapped. Transfer to a baking sheet and bake for an hour*. Rotate the roll every 20 minutes for even cooking.
  • * I may update the time in this recipe because I’ve gotten a few comments that said it took up to 90 minutes to cook completely! So for now I would say just do a test my poking the roll with tongs. It should feel very very firm. If it doesn’t, then bake further.
  • Remove from oven and let cool. Unwrap, slice and serve! (See recipe notes for keeping moist and reheating.).
  • ~For best results, use a salty homemade vegetable broth. Salt is integral to the flavor of the seitan, so if your broth isn’t seasoned then add a teaspoon or so of salt to it.
  • ~You’ll also want to spoon broth over the roast before serving, to keep it from being dry. Of course you’re going to be coating it in gravy, too. But the broth is a nice touch. If you’re slicing and serving, ladle on spoonfuls of broth on each individual slice, too. You can’t have too much juice, here!
  • ~This roast reheats perfectly. Refrigerate in its wrapper for up to 3 days before hand. When ready to serve, preheat an oven to 350 F and cook for 20 minutes. This will dry it out a bit, so use the broth hints above for sure!
  • ~Use a steak knife for the easiest slicing.
  • ~I used storebought breadcrumbs but if you use homemade, use 3/4 cup.
  • ~This makes enough for 6 hungry people. If it’s not Thanksgiving or another holiday, and people are not totally stuffing their faces, it serves at least 8.
