Ingredients

• 680 g (24 oz) cremini (baby bella) mushrooms, finely chopped

• 1 cup (100 g) walnuts, toasted and finely ground

• 1 cup (185 g) cooked quinoa or brown lentils

• 1 large onion, finely diced

• 3 cloves garlic, minced

• 2 large eggs (or flax eggs for vegan)

• 1 cup (60 g) panko breadcrumbs (gluten-free if needed)

• 2 tablespoons soy sauce or tamari

• 2 tablespoons olive oil

• 1 tablespoon fresh thyme, chopped

• Salt and black pepper, to taste

Glaze

• ¼ cup (60 ml) ketchup

• 1 tablespoon balsamic glaze

• 1 teaspoon Dijon mustard

Instructions

1. Preheat oven to 375°F (190°C) and line a loaf pan with parchment paper.

2. Heat olive oil in a large skillet over medium-high heat. Add mushrooms and onion, cooking until all moisture evaporates and the mixture is deeply browned, about 12–15 minutes.

3. Add garlic and thyme in the last 2 minutes of cooking, stirring until fragrant.

4. Transfer the mixture to a large bowl and let cool slightly.

5. Add ground walnuts, cooked quinoa, breadcrumbs, soy sauce, and eggs. Season with salt and pepper, then mix until well combined.

6. Press firmly into the loaf pan and compact well to help prevent crumbling after baking.

7. In a small bowl, whisk together ketchup, balsamic glaze, and Dijon mustard. Spread evenly over the top.

8. Bake 40–45 minutes until firm around the edges and lightly browned on top.

9. Let rest for at least 15 minutes before slicing. Cutting too early can cause the loaf to fall apart.

• Cook mushrooms thoroughly until browned to avoid a mushy texture
