Recommended Products for This Recipe
After making this recipe countless times, I’ve found a few products that really make a difference in the final result.
These aren’t necessary, but they’ll help you achieve the best possible pot roast.
1. Crock-Pot 6-Quart Programmable Slow Cooker
This programmable slow cooker has been my go-to for years because it automatically switches to warm when cooking is done.
You never have to worry about overcooking your vegetables, and the digital timer takes all the guesswork out of meal planning.
2. Better Than Bouillon Vegetable Base
This concentrated vegetable base creates a much richer, more flavorful broth than regular boxed versions.
A little goes a long way, and it adds incredible depth to the gravy without any artificial flavors.
3. San-J Tamari Gluten-Free Soy Sauce
I prefer tamari over regular soy sauce because it has a smoother, less salty flavor that doesn’t overpower the vegetables.
The gluten-free version works perfectly for anyone with dietary restrictions while still delivering that umami richness.
4. Wusthof Classic Chef’s Knife
A sharp chef’s knife makes prep work so much faster and safer. This knife glides through potatoes, carrots, and celery with ease, cutting your prep time in half compared to a dull blade.

Step-by-Step Instructions: How to Make Slow Cooker Vegan Pot Roast
Follow these detailed steps for a perfectly cooked pot roast every single time. The key is layering the vegetables properly and not rushing the cooking process.
1. Prepare Your Vegetables
- Wash all vegetables thoroughly under cold running water
- Cut the baby potatoes in half so they cook evenly with the other vegetables
- Peel and cut the carrots into 2-inch chunks for the best texture
- Quarter the onion, keeping some of the root end attached to each piece so they hold together
- Cut celery stalks into similar-sized chunks as the carrots
- Clean and halve the mushrooms, removing any dirt with a damp paper towel
- Mince the garlic finely or press it through a garlic press for maximum flavor
2. Layer Ingredients in the Slow Cooker
- Place the potatoes on the bottom of your slow cooker as they take the longest to cook
- Add the carrots, onion, and celery on top of the potatoes
- Scatter the mushrooms over the other vegetables
- Sprinkle the minced garlic evenly across the top
3. Make the Braising Liquid
- In a medium bowl, whisk together the vegetable broth, soy sauce, and tomato paste until smooth
- Add the balsamic vinegar and whisk again to combine fully
- Stir in the dried thyme and rosemary, making sure they’re evenly distributed
- Pour this mixture carefully over all the vegetables in the slow cooker
- Tuck the bay leaves down into the liquid where they can infuse maximum flavor
4. Cook Low and Slow
- Cover the slow cooker with its lid, making sure it’s sealed properly
- Set the temperature to low and cook for 6-8 hours, or high for 4-5 hours
- Resist the urge to lift the lid during cooking as this releases heat and extends cooking time
- The vegetables are done when you can easily pierce the potatoes with a fork
5. Thicken the Gravy
- About 30 minutes before serving, mix the cornstarch and cold water in a small bowl until completely smooth
- Remove about 1 cup of the hot cooking liquid from the slow cooker
- Slowly whisk the cornstarch slurry into the removed liquid
- Pour this mixture back into the slow cooker, stirring gently to distribute
- Cover and cook for another 30 minutes on high until the gravy thickens beautifully
6. Season and Serve
- Remove and discard the bay leaves before serving
- Taste the gravy and add salt and freshly ground black pepper as needed
- Use a large spoon to gently stir everything together, being careful not to break up the vegetables
- Serve hot in deep bowls with plenty of gravy spooned over the top

Tips for The Best Slow Cooker Vegan Pot Roast

FAQs About Slow Cooker Vegan Pot Roast
1. Can I use sweet potatoes instead of regular potatoes?
Absolutely! Sweet potatoes work beautifully in this recipe and add natural sweetness.
Cut them into slightly larger chunks than baby potatoes since they tend to break down more during the long cooking time.
2. Do I need to add oil to this recipe?
No oil is necessary for this recipe. The vegetables release their own moisture, and the broth provides plenty of liquid. This keeps the dish naturally low in fat while maintaining rich flavor.
3. Can I make this in an Instant Pot instead?
Yes, you can adapt this recipe for an Instant Pot. Use the sauté function to mix the broth and seasonings, then pressure cook on high for 15 minutes with natural release. You’ll still need to thicken the gravy at the end.
4. What can I substitute for soy sauce?
Coconut aminos make an excellent soy sauce substitute if you’re avoiding soy or want lower sodium.
Tamari works well if you need a gluten-free option. Either one provides the same savory depth.
5. Why is my gravy still watery after adding cornstarch?
The gravy needs time and heat to thicken after adding the cornstarch slurry. Make sure you cook it on high for the full 30 minutes after adding the thickener.
If it’s still thin, mix another tablespoon of cornstarch with cold water and stir it in.
