Step‑by‑Step Instructions for Impossible Vegetarian Meatloaf

Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (186°C). While the oven warms up, grab a food processor and add the button mushrooms, finely chopped onion, and minced garlic. Blitz them together until you achieve a rough chop, ensuring the mixture retains a bit of texture to enhance the Impossible Vegetarian Meatloaf later.

Step 2: Mix Ingredients Together
In a large mixing bowl, combine the blitzed mushroom mixture with the Impossible Ground Burger, breadcrumbs, Italian seasoning, vegan Worcestershire sauce, and salt. Add the whisked eggs to the bowl, and mix everything thoroughly until you have a well-combined and homogenous mixture that holds together nicely—this is key for your meatloaf’s structure!

Step 3: Prepare the Topping
In a separate small bowl, mix together the ketchup, brown sugar, and mustard until smooth. This tangy topping will not only enhance the flavor but will also create a beautiful glaze on your Impossible Vegetarian Meatloaf as it bakes, adding a touch of sweetness and brightness to every slice.

Step 4: Assemble the Meatloaf
Line a 9×5 inch loaf pan with parchment paper for easy removal. Firmly press the meatloaf mixture into the pan, ensuring there are no air pockets and that it is evenly shaped. Spread half of the prepared ketchup topping over the mixture, coating it generously to create a flavorful crust.

Step 5: Bake the Meatloaf
Place your assembled meatloaf in the preheated oven and bake uncovered for 30 minutes. After this initial baking time, carefully remove the loaf and spread the remaining ketchup mixture on top, enhancing the glaze further. Return it to the oven and bake for an additional 30 minutes until nicely browned and firm.

Step 6: Cool and Slice
Once baked, remove your Impossible Vegetarian Meatloaf from the oven and let it cool for about 10 minutes. This cooling step is essential as it allows the loaf to firm up, making it easier to slice. Once cooled slightly, slice into portions and serve warm, enjoying the delicious flavors together with your favorite side!

Impossible Vegetarian Meatloaf Recipe FAQs

What type of mushrooms should I use for the best flavor?
Absolutely! Button mushrooms are great, but if you want a richer flavor, I recommend using portobello mushrooms. They provide a heartier texture and deeper umami taste to the Impossible Vegetarian Meatloaf, making it even more satisfying for both vegetarians and meat lovers.

How should I store leftover Impossible Vegetarian Meatloaf?
Very! Refrigerate leftovers in an airtight container for up to 5 days. If you’d like to keep it longer, you can freeze it! Just wrap the meatloaf tightly in plastic wrap and then place it in a freezer-safe bag to avoid freezer burn. It keeps well in the freezer for up to 3 months!

Can I freeze the Impossible Vegetarian Meatloaf?
Absolutely! To freeze, allow the meatloaf to cool completely after baking. Wrap it securely in plastic wrap, then place it in a freezer-safe bag. When you’re ready to enjoy it again, simply thaw it in the refrigerator overnight and reheat it in the oven at 350°F (175°C) for about 20-25 minutes until warmed through.

What if my meatloaf falls apart when slicing?
Ah, a common concern! To avoid crumbling, ensure you let the Impossible Vegetarian Meatloaf rest for at least 10 minutes after baking before slicing. This allows it to set up a bit, making it easier to cut clean slices. Additionally, ensure all ingredients are well mixed—those breadcrumbs and eggs are key for binding!

Is this recipe suitable for my gluten-free guests?
Very much so! If you need a gluten-free version, simply substitute the breadcrumbs with crushed oats. This will maintain the texture while accommodating gluten sensitivities. Just be sure to check that the oats are certified gluten-free.

Are there any allergies I should be aware of?
Definitely! This Impossible Vegetarian Meatloaf contains eggs for binding. If you’re cooking for someone who is vegan or has an egg allergy, you can replace the eggs with flaxseed eggs. To make a flaxseed egg, simply mix 1 tablespoon of ground flaxseed with 2.5 tablespoons of water and let it sit for about 5 minutes until it thickens.
