Step‑by‑Step Instructions for Impossible Vegetarian Meatloaf

Step 1: Preheat and Blitz
Preheat your oven to 350°F (186°C) to ensure even baking. In a food processor, combine 1 pound of button mushrooms, half of a white onion, and three cloves of garlic. Blitz the mixture until it’s roughly chopped—aim for a texture similar to coarse breadcrumbs. This mixture will infuse your Impossible Vegetarian Meatloaf with incredible flavor.

Step 2: Mix Ingredients
In a large mixing bowl, combine the blitzed mushroom mixture with the remaining meatloaf ingredients, including one package of Impossible Ground Burger, one cup of breadcrumbs, one tablespoon of Italian seasoning, one tablespoon of vegan Worcestershire sauce, and half a teaspoon of salt. Add two whisked large eggs to bind everything together, mixing until fully incorporated for a robust consistency.

Step 3: Prepare Topping
In a separate bowl, prepare the topping for your Impossible Vegetarian Meatloaf by mixing half a cup of ketchup, one tablespoon of brown sugar, and one tablespoon of mustard. Stir until the ingredients are well blended, creating a sweet and tangy glaze that will enhance the deliciousness of your meatloaf as it bakes.

Step 4: Assemble the Meatloaf
Line a loaf pan with parchment paper for easy removal later. Pack the meatloaf mixture tightly into the prepared pan, ensuring there are no gaps. Once evenly shaped, spread about half of the prepared ketchup topping over the top of the meatloaf, creating a glossy finish that promises delightful flavor.

Step 5: Bake to Perfection
Bake your meatloaf uncovered in the preheated oven for 30 minutes at 350°F (186°C). After the initial time, carefully add the remaining ketchup topping to the loaf and continue baking for an additional 30 minutes. You’ll know it’s done when the edges are slightly crisp and the center is hot and firm to the touch.

Step 6: Cool and Serve
Once baked, remove the Impossible Vegetarian Meatloaf from the oven and allow it to cool for 10 minutes in the pan. This resting period will help the juices redistribute, ensuring a moist and flavorful slice. After cooling, carefully lift the meatloaf out of the pan using the parchment paper and slice it into hearty portions for serving.
