Jump to Recipe Print Recipe

I’ve been experimenting with seitan for years, and this herb-crusted version has become my go-to when I want something that feels special but doesn’t require hours in the kitchen. Seitan, made from vital wheat gluten, creates this wonderfully meaty texture that takes on flavors beautifully. When you bake it with a coating of fresh herbs and spices, it develops this gorgeous golden crust that’s absolutely satisfying.

The technique here is pretty straightforward. You’re making a simple seitan dough, shaping it into a tenderloin-like log, then coating it with a mixture of fresh herbs, garlic, and olive oil before baking. The key is getting the seitan mixture just right. Too wet and it won’t hold its shape. Too dry and it becomes tough. I’ve found that kneading it for about 8 minutes gives you that perfect chewy texture that holds up to slicing.

Getting the Seitan Texture Right

What I love about this recipe is how it bridges the gap between weeknight dinner and something you’d serve to guests. The herb coating isn’t just for show. It creates this fragrant crust that seals in moisture while adding layers of flavor. Fresh rosemary and thyme work best here, but you can absolutely use what you have on hand.

Why Fresh Herbs Make All the Difference

This pairs beautifully with roasted vegetables or a simple grain pilaf. I often serve it alongside roasted carrots and potatoes for a complete meal. It’s also fantastic sliced thin for sandwiches the next day. The leftovers actually get better after a day in the fridge, which makes meal prep a breeze.

Ingredients Method Notes

Ingredients
  

For the Seitan
  • 1½ cups vital wheat gluten
  • ¼ cup nutritional yeast
  • 1 teaspoon kosher salt
  • ½ teaspoon garlic powder
  • ½ teaspoon onion powder
  • ¼ teaspoon black pepper
  • 1 cup vegetable broth warm
  • 2 tablespoons soy sauce
  • 2 tablespoons olive oil
For the Herb Coating
  • 3 tablespoons olive oil
  • 2 tablespoons fresh rosemary minced
  • 2 tablespoons fresh thyme leaves
  • 3 cloves garlic minced
  • 1 teaspoon kosher salt
  • ½ teaspoon black pepper
  • 1 tablespoon fresh lemon juice

Method
 

Prepare the Seitan
  1. Preheat your oven to 375°F. Line a baking sheet with parchment paper.
  2. In a large bowl, whisk together vital wheat gluten, nutritional yeast, salt, garlic powder, onion powder, and black pepper.
  3. In a separate bowl, combine warm vegetable broth, soy sauce, and 2 tablespoons olive oil.
  4. Pour the wet ingredients into the dry ingredients and mix with a wooden spoon until a shaggy dough forms.
  5. Turn the dough onto a clean surface and knead for 8-10 minutes until smooth and elastic. The dough should be firm but not dry.
  6. Shape the seitan into a log about 8 inches long and 3 inches wide, similar to a tenderloin shape.
Make the Herb Coating and Bake
  1. In a small bowl, combine 3 tablespoons olive oil, minced rosemary, thyme, garlic, salt, pepper, and lemon juice. Mix well.
  2. Place the seitan log on the prepared baking sheet and brush the herb mixture all over the surface, using your hands to press the herbs into the seitan.
  3. Bake for 35-40 minutes, until the surface is golden brown and firm to the touch.
  4. Remove from oven and let rest for 10 minutes before slicing.
  5. Slice diagonally into ½-inch thick pieces and serve immediately.

Notes

The seitan can be made up to 3 days ahead and stored in the refrigerator. Reheat slices in a 350°F oven for 10 minutes. If you don't have fresh herbs, use 1 tablespoon each of dried rosemary and thyme. The texture improves after resting, so don't skip that 10-minute rest period before slicing.
