Preheat your broiler or grill to medium-high.
Arrange the baguette slices on a baking sheet. Lightly brush both sides of each slice with extra-virgin olive oil.
Heat the 1 tablespoon (15 ml / 0.5 fl oz) of olive oil in a large skillet over medium heat.
Add the minced garlic and cook until fragrant, about 1 minute.
Stir in the finely chopped mushrooms, dried basil, marjoram, and savory.
Season to taste with salt and pepper.
Cook, stirring occasionally, until the mushrooms have released their liquid and are soft and browned, about 5 to 7 minutes.
Remove the skillet from the heat and stir in the fresh parsley.
Keep the mixture warm.
Place the baking sheet with the bread under the broiler or on the grill. Toast for 1-2 minutes per side, until golden brown and crisp. Watch carefully to prevent burning.
Spoon the hot mushroom mixture evenly over the toasted bread slices.
Serve immediately.
