Perfect for Halloween gatherings, themed dinner parties, or fun fall entertaining, this recipe combines earthy sautéed mushrooms, buttery toasted bread, gooey cheese, and tangy balsamic vinegar.

Ingredients

• 1 1/4 lbs small white button mushrooms
• 1 baguette
• 6 oz grated gruyere cheese
• 6 tbsp (88.7ml) butter
• Fresh thyme
• Balsamic vinegar
• Red pepper flakes
• 1 clove garlic

Method

• Start by cutting your mushrooms in half. Using a small piping tip, cut two holes into the rounded half of the mushroom caps to create eyes. Using a paring knife, cut short parallel lines on the stems to create teeth.
• Sauté the mushrooms in butter with some chopped thyme, garlic and chili flakes. Season with salt and deglaze with balsamic vinegar.
• Slice baguette on a bias and toast in a pan with butter. Once toasted on both sides, add cheese and melt in a hot oven. Top off with sautéed mushrooms and garnish with thyme.
