# Ingredients:

→ Base Ingredients

01 - 3 tablespoons butter
02 - 1 cup onion, finely chopped
03 - 2 cups mushrooms, chopped
04 - 1 cup mozzarella cheese, shredded, plus extra for topping
05 - ¼ cup parmesan cheese, grated or shredded
06 - 1 large egg
07 - Dried oregano, to taste
08 - ¼ teaspoon salt
09 - ½ teaspoon black pepper
10 - 1 baguette, sliced
11 - Olive oil for drizzling (optional)

# Instructions:

01 - Preheat oven to 175°C (350°F).
02 - Slice baguette into approximately 2 cm (¾ inch) thick slices. Set aside.
03 - In a large skillet, melt the butter over medium heat. Add the chopped mushrooms and sauté for 2-3 minutes.
04 - Add chopped onions to the skillet and continue cooking until both mushrooms and onions are tender and golden, about 5-7 minutes.
05 - Sprinkle oregano, salt, and pepper over the mushroom-onion mixture, stirring to incorporate.
06 - Reduce heat to low. Add the shredded mozzarella and parmesan cheese to the skillet, stirring until the cheese begins to melt.
07 - Crack the egg into the mixture and stir continuously for about a minute until fully incorporated and slightly thickened.
08 - Remove the skillet from heat once the mixture is well combined.
09 - Line a rimmed baking sheet with parchment paper.
10 - Place the baguette slices on the prepared baking sheet. Top each slice with a generous spoonful of the mushroom mixture. Sprinkle a pinch of additional mozzarella cheese on top of each toast.
11 - If desired, lightly drizzle each toast with olive oil for extra flavor and browning.
12 - Bake in the preheated oven for 12-15 minutes, until the cheese is fully melted and the edges of the bread are golden brown.
13 - Serve the toasts immediately while warm.

# Notes:

01 - For best results, use fresh mushrooms and day-old baguette which will hold the topping better.
02 - These appetizer toasts can be prepared ahead of time and baked just before serving.
