Your Go-To Meatloaf Recipe

Lately, I’ve been on a mission to recreate all the classics—vegetarian style (you know, shepherd’s pie, Italian meatballs, stroganoff, and the like). But there was a hole in my recipe lineup—a loaf-shaped hole. So… let’s make meatloaf!

This meatless masterpiece combines mushrooms, onions, and garlic with Impossible meat (that tastes just like the real deal!). It turns out so savory and hearty that I guarantee you won’t miss the meat even a bit!

Grab These Ingredients

We’re using two sets of ingredients: those for the mushroom meatloaf and those for the ketchup topping. Jump to the recipe card for exact measurements—this is just an overview!

• Mushrooms: I like to add button mushrooms (a.k.a. cremini or common mushrooms), but you can use brown or white mushrooms (learn about the different types of mushrooms here!).
• Flavor Base: We’ll pulse the mushrooms with white onion and garlic for the ultimate savory flavor boost.
• Veggie Meat: For our “meat,” we’re using Impossible Foods Ground Burger Meat! (You will need a 12-oz package for this recipe.)
• Breadcrumbs: We’ll include breadcrumbs to soak up excess moisture and give the loaf structure.
• Seasonings: For flavor, add an Italian seasoning blend and salt.
• Worcestershire Sauce: From there, use a touch of Worcestershire sauce (aim for the vegan kind if you’re strictly veg).
• Eggs: Finally, a couple of whisked eggs will help bind the loaf together!
• Glaze: We’re keeping things simple with a mix of ketchup, brown sugar, and mustard! Use your favorite ketchup and mustard brands here.

Making Vegetarian meatloaf Is Easy

It doesn’t take much effort to create a rockin’ vegetarian meatloaf! For the full printable instructions, jump to the recipe card.

Step 1: Blitz The Savory Base
Preheat the oven to 350°F (186°C). Add the mushrooms, onion, and garlic to a food processor and blitz until roughly broken down.

Step 2: Combine The Ingredients
Stir the mushroom mixture and the remaining meatloaf ingredients in a bowl.

Step 3: Create The Glaze
In a separate bowl, stir together all of the ketchup topping ingredients.

Step 4: Assemble The Meatloaf
Line a loaf pan (9×5 inch) with parchment paper. Spoon your mushroom meatloaf mixture into the pan, pressing to fill any gaps or empty corners. Spoon half of the glaze onto the meatloaf, spreading it evenly over the top.

Step 5: Bake And Add Ketchup
Bake, uncovered, for 30 minutes. Remove from the oven, spread the remaining ketchup over the top, and bake for another 30 minutes. Cut into slices and enjoy!

Add Extra Mix-Ins

Green peppers are a great option if you want to add extra veggies to your Impossible meatloaf! Be sure to chop them into small pieces (or blitz alongside the mushrooms and onion).

You can also add cheese—I recommend mozzarella. Bake it right in the meatloaf (include it in step 2!).

Feeling herby? You can also add some basil and/or oregano for extra flavor!
