3 tablespoons brown sugar – Adds a hint of caramel-like sweetness to the glaze.
½ teaspoon apple cider vinegar (optional) – Brightens the flavors in the glaze with a touch of acidity.
⅛ teaspoon salt – Enhances all the flavors of the glaze.
2 ½ tablespoons ground flaxseed – Used as an egg substitute to bind the loaf.
6 tablespoons water – Helps activate the ground flaxseed.
2 tablespoons avocado oil – Contributes to the sautéing process for veggies while keeping it healthy.
1 medium red onion, diced small – Adds sweetness and depth to the meatloaf mix.
3 stalks celery, diced small – Provides crunch and freshness, balancing the dish beautifully.
3-4 cloves garlic, minced – Infuses the loaf with a delightful aromatic flavor.
12 ounces cremini mushrooms, finely chopped or minced (about 4 cups) – The star of our meatloaf, giving it a rich, umami flavor.
2 cups cooked rice – Creates the ideal base, making the loaf hearty and filling.
1 cup cooked potatoes, mashed (measured mashed) – Adds creaminess and a comforting texture to the loaf.
¾ cup rolled oats – Acts as a binding agent, providing additional fiber.
⅓ cup breadcrumbs – Gives the loaf a nice crust and texture.
¾ cup walnuts, pulsed in food processor into a loose meal (or finely chopped) – Adds crunch and nuttiness, complementing the mushrooms wonderfully.
3 tablespoons tomato paste – Enhances overall flavor and adds richness to the mixture.
1 teaspoon dried thyme – Introduces an earthy note that pairs perfectly with mushrooms.
1 ½ teaspoons dried parsley – Brightens the mixture with fresh herbaceousness.
¾ teaspoon ground sage (optional) – Adds a warm, savory flavor reminiscent of cool weather.
1 teaspoon dried rosemary – Offers woody notes that enhance the dish’s heartiness.

How to Make Vegan Mushroom Meatloaf

Follow these simple steps to prepare this delicious Vegan Mushroom Meatloaf:

Step 1: Prepare the Glaze
In a small bowl, whisk together the ketchup, mustard, brown sugar, apple cider vinegar, and salt. Set the glaze aside to let the flavors meld together.

Step 2: Preheat Your Oven
Preheat your oven to 375°F (190°C). While the oven is warming up, prepare your loaf pan by lining it with parchment paper, making it easier to remove later.

Step 3: Activate the Flaxseed
In another small bowl, combine the water and ground flaxseed. Let it sit for at least 10 minutes until it thickens to form a flax egg, which will help bind the loaf.

Step 4: Sauté the Veggies
In a large pan over medium heat, heat the avocado oil. Add the diced onion and celery with a sprinkle of salt, sautéing for 5-6 minutes until the onions are lightly golden and the celery has softened. Stir in the minced garlic, thyme, rosemary, parsley, and sage, cooking for another 30-60 seconds until fragrant.

Step 5: Cook the Mushrooms
Increase the heat to medium-high and add the chopped mushrooms to the pan. Spread them evenly and let them cook undisturbed for 2-3 minutes until they release their liquid and start to brown. Stir and cook for an additional 2-3 minutes until nicely golden.

Step 6: Combine Ingredients
Transfer the sautéed mixture to a large mixing bowl. Add in the mashed potatoes, breadcrumbs, flax egg, cooked rice, rolled oats, chopped walnuts, tomato paste, Worcestershire sauce, along with salt and pepper. Use your hands or a spoon to mix everything together thoroughly, ensuring a consistent texture.

Finally, transfer the mixture into the lined loaf pan and press it down firmly. Brush the top generously with your prepared ketchup glaze.

Let the baking begin! Pop it into the oven for about 30-40 minutes until heated through. If you’re feeling a little fancy, you can turn on the broiler for the last 2-3 minutes to give that glaze a nice crisp but keep an eye on it to avoid burning.

Once done, allow the loaf to cool for approximately 10 minutes before using the parchment paper to lift it out of the pan. For the best slicing experience, let it rest for another 10 minutes before serving. Enjoy this delightful Vegan Mushroom Meatloaf with your favorite sides, and prepare for compliments from all around!
