This one-pot vegan seitan pot roast is a cozy, hearty plant-based dinner made with tender homemade seitan, potatoes, carrots, red onion, garlic, and fresh parsley in a savory vegetable broth. It’s a comforting, rustic meal inspired by traditional pot roast, made entirely on the stovetop in one pot.
This seitan is made from a simple combination of vital wheat gluten, chickpea flour, whole wheat flour, nutritional yeast, and savory seasonings. Instead of preparing the seitan separately, you’ll knead the dough right in your stock pot and let it slowly braise in the vegetable broth before adding the vegetables.
The result is a tender, pull-apart seitan roast surrounded by soft vegetables and a flavorful broth. Add a splash of vegan red wine for extra depth, or keep it simple with vegetable broth and fresh herbs.
If you’re looking for a satisfying vegan pot roast made with pantry staples, this recipe is a cozy addition to your plant-based dinner rotation.

How To Make One-Pot Seitan Pot Roast
Step 1: Mix the dry ingredients
Before turning on the stove, add the vital wheat gluten, chickpea flour, whole wheat flour, mushroom bouillon powder, nutritional yeast, garlic powder, thyme, salt and black pepper to a large stock pot.
Whisk everything together until dry ingredients and seasonings are evenly distributed.
Step 2: Mix the wet ingredients
Warm 1 cup of vegetable broth. Whisk in the tomato paste, barbecue sauce, and olive oil until combined.
Slowly pour the wet mixture into the dry ingredients in approximately 3 additions, stirring between each pour. Continue mixing until the dough begins to form.
Step 3: Knead the seitan dough
Set a timer for 5 minutes and knead the dough by hand directly inside the stockpot. Fold the dough over itself repeatedly throughout the kneading process.
The mixture will be sticky, so use kitchen gloves if you prefer. Continue folding and kneading until the ingredients come together in a cohesive dough.
Shape the dough into a large rounded loaf in the center of the pot.
Step 4: Begin braising the seitan
Pour 3 cups of vegetable broth over the seitan loaf. Cover the pot and place it on the stovetop over low heat.
Braise for approximately 2 hours, checking periodically to ensure there is enough liquid in the pot to keep the seitan from drying out.
Important: The seitan may stick to the bottom of the pot as it cooks. After approximately 30 minutes, carefully release the loaf from the bottom of the pan using a suitable utensil. Cover and continue cooking.
Around the 45-minute mark, release the seitan from the bottom again and add another cup of vegetable broth. Cover and continue braising.
After that, check approximately every 15 minutes, releasing any areas that have stuck. Let the steam escape before reaching into the pot, and use a long-handled utensil to protect your hands from hot steam.
Add more broth as necessary to maintain moisture throughout the cooking process. (But remember – we are braising, not boiling. It should be at a simmer with vegetable broth covering only the bottom half of the loaf to allow the top to cook from the steam.)
Step 5: Break the seitan into chunks
Once the seitan has braised for approximately 2 hours, use a sturdy spatula to divide the loaf into large, rustic chunks.
I used a frosting spatula for this, and the seitan was tender enough to separate easily. The irregular pieces give the finished pot roast a hearty, homemade appearance.
Step 6: Add the potatoes, carrots, onion, and garlic
Add the following ingredients to the pot:
- Prepare potatoes, cut into large chunks
- Carrots, cut into pieces if using large carrots
- Half a large red onion, cut into 6 sections
- Minced fresh garlic
- 1 cup vegetable broth
If you’d like a deeper richer flavor, add 1/4 cup vegan red wine at this stage.
Stir gently to distribute the vegetables and broth around the seitan chunks.
Step 7: Simmer until tender
Cover the pot and cook for another 30 minutes to 1 hour over low heat, or until the potatoes and carrots are tender.
The seitan should be very tender and easy to pull apart (though it will not shred like traditional pot roast), while the vegetables should be soft without completely losing their shape.
Check the liquid level while cooking and add a little more vegetable broth if needed.
Step 8: Season and finish with fresh parsley
Taste the broth (which should be very reduced and thickened at this point) and add salt and black pepper as needed. If you don’t have mushroom bouillon powder, you can use soy sauce or tamari to add savory depth, adjusting the salt accordingly.
Remove the pot from the heat and stir in fresh parsley.
Serve warm with plenty of vegetables, tender seitan, and savory broth in every bowl.
Tips for the Best Homemade Seitan Pot Roast
Keep the heat low. Gentle braising helps the seitan cook slowly while keeping the pot moist. Avoid letting the broth boil away.
Release the seitan from the bottom regularly. This is an important part of this particular one-pot method. Check more frequently during the second hour, and add broth when needed.
Cut the vegetables in large chunks. Larger pieces hold up better during the final simmer and give the finished dish a traditional pot-roast feel.
Choose your potatoes based on texture. Russet potatoes become softer and can help thicken the broth, while golden potatoes generally hold their shape better. Peel russets if you prefer a softer texture.
Adjust the broth to your liking. Keep enough liquid in the pot to prevent drying and to cook the vegetables. Add more if you prefer a brothier finish.
Don’t skip the fresh parsley. Stirring it in after cooking adds a fresh, herbal contrast to the rich and savory broth.
Substitutions and Variations
- No mushroom bouillon? Use soy sauce or tamari for extra umami, adjusting the other salt to taste. Because these are not a direct one-to-one replacement for bouillon powder, start with a modest amount and taste.
- No red onion? Yellow or white will work.
- Prefer richer broth? Add the optional vegan red wine with the vegetables.
- Want softer potatoes? Peel the russets and cut them into generous chunks.
- Using baby carrots? Leave them whole if they’re small, or cut larger ones in half.
How to Store and Reheat
Allow leftovers to cool and transfer them to an airtight container. Refrigerate promptly and enjoy within 3-4 days.
Reheat gently on the stovetop over low heat, adding a splash of vegetable broth if the liquid has thickened or reduced. You can also reheat individual portions in the microwave until thoroughly hot.
For the best texture, store the seitan, vegetables, and broth together so the seitan retains moisture.
Frequently Asked Questions
Is seitan a good substitute for pot roast?
Seitan is primarily made from vital wheat gluten and has a chewy, savory texture that works well in hearty plant-based meals. In this recipe, braising it with vegetable broth and traditional pot-roast vegetables creates a satisfying alternative to a conventional roast.
Can I make this without a separate steamer or oven?
Yes. This recipe uses a stock pot for both preparing and braising the seitan, followed by cooking the vegetables in the same pot. No separate steamer or oven is required.
Why does the seitan need to be released from the bottom of the pot?
The dough can stick as it cooks. Carefully loosening it at intervals and maintaining sufficient broth helps prevent it from sticking too firmly or drying out.
Can I use russet or golden potatoes?
Yes. Russet potatoes are ideal if you prefer a softer texture, while golden potatoes tend to maintain their shape a little better during simmering.
Can I add red wine to vegan pot roast?
Yes. A small amount of vegan red wine adds richness and depth to the broth. Check the wine’s ingredients / production information if you want to ensure it’s vegan.
