❤️ Why you’ll love it

This comforting vegan recipe truly stands out from the crowd for its satisfying heartiness and depth of flavor. It proves that vegan food can be just as enjoyable and delicious as meat-based dishes.

I love the delicious, hearty, meaty flavor you get without using any meat at all. I kept the sauce rich, thick, and robust with the help of various vegetables.

Beets add a delicious richness to the sauce and contribute to darker, deeper colors and flavors reminiscent of its non-vegan counterpart. Plus, the flavorful red wine gravy adds further depth for an authentic classic you will love.

By including large caps of portobello mushrooms in this roast, the texture is incredible! They have a spongy, beefy, and tough texture, but they taste-neutral, so incorporating the right mix of seasonings makes them delicious.

Over the years of being a vegan, I have learned that mushrooms are one of the best plant-based meat substitutes. While there are many other options like tempeh, seitan, jackfruit, and whole cauliflower head, you will get the best results using mushrooms, as I have in this recipe.

? Equipment

For this hearty vegan pot roast recipe, the most essential piece of equipment you will need is an enameled Dutch oven.

?‍? Instructions

Preparing the ingredients

STEP 1
Start by preparing your vegetables. Peel and slice your onion, then peel and finely chop your garlic. Next, wash, peel, and chop your potatoes, carrots, beetroot, and parsnip. If you have young carrots and parsnips, you can use them whole. Lastly, clean your mushrooms gently with a damp cloth and remove the stems.

STEP 2
Next, preheat your oven to 375 degrees Fahrenheit (190 degrees Celsius).

? Expert tip

For this vegan pot roast, the key to unlocking the most flavor lies in the initial sautéing of the onions and garlic in olive oil. Don’t rush this step—allow the onions to become translucent and the garlic to soften, releasing their aromatic compounds. This forms a flavor foundation that deeply infuses the entire dish, making every bite rich and savory.

? Variations

Try adding some protein to this vegan pot roast. Tofu or chickpeas would be a great addition. Simply drain and rinse your chickpeas or press and cube your tofu, then add them to the dish during the last half hour of cooking. This will make the dish even more filling and add a different texture.

For a more earthy flavor, add some root vegetables like turnips or rutabagas. Simply peel and chop them into bite-sized pieces, then add them to the other vegetables. This will give the dish a unique taste and make it even more hearty.

If you want a thicker gravy, add some lentils. Rinse and drain them before adding to the dish. They will absorb some of the liquid and thicken the sauce, adding a boost of protein and fiber.

? Serving ideas

This vegan pot roast is a hearty and satisfying main dish perfect for any occasion. The robust flavors in this dish complement the freshness of salads perfectly. Try serving it alongside a crisp kale and apple salad, a tangy beetroot and quinoa salad, or a refreshing cucumber and tomato salad.

While it does contain potatoes, many like it to be served with mashed potatoes.

It pairs well with other plant-based starters like stuffed mushrooms, pistachio nut cheese, or vibrant beetroot hummus.

❄️ Storing tips

Storing and reheating this vegan pot roast is a breeze and doesn’t sacrifice any of its hearty, comforting flavor. It may taste better after a day or two as the flavors from the portobello mushrooms and various veggies have had more time to mingle in the rich red wine gravy.

To store, allow it to cool completely before transferring it to an airtight container. It can be safely stored in the refrigerator for up to four days. Keep any leftover gravy in a separate container, as it can be used to moisten the roast when you’re ready to reheat it.

As for freezing, this dish is unsuitable due to the variety of vegetables used. Certain vegetables, like potatoes, can become grainy and lose their texture when frozen and then thawed. However, the red wine gravy can be frozen separately in an airtight container for up to three months and used in other recipes.

When you’re ready to reheat it, place it in a pan over medium heat on the stovetop. Add a splash of the leftover gravy or a bit of vegetable broth to keep it moist and flavorful. Cover the pan and allow it to heat through, stirring occasionally to ensure it heats evenly. If you’re using a microwave, be sure to stir the roast every minute or so for even reheating.

? FAQs

What kind of mushrooms should I use for this vegan pot roast?

For this recipe, I recommend using large portobello mushroom caps. They have a rich, meaty texture that works well in this hearty dish, and they hold up well to the long cooking time.

Can I use other vegetables in this recipe?

Absolutely! This recipe is very versatile. You can substitute or add other root vegetables like turnips or sweet potatoes. Remember that the cooking time may vary depending on the vegetables you use.

What can I use instead of red wine?

If you prefer not to use red wine, you can substitute it with additional veggie broth or a non-alcoholic red wine. The wine adds depth to the flavor, but the recipe will still be delicious without it. If you follow the whole food plant-based diet, grape juice can also be a suitable option.

What is the purpose of the corn starch in this recipe?

Cornstarch is used to thicken the gravy in this recipe. If you don’t have cornstarch, you can substitute it with all-purpose flour. Just cook it for a few minutes to remove the raw flour taste.
