The key to this dish lies in selecting the right ingredients — fresh, wholesome, and full of flavor. Over the years, I’ve learned that quality mushrooms make all the difference, and using freshly grated cheese elevates the whole experience. When it comes to garlic, I always prefer fresh cloves over pre-minced — the flavor is simply unbeatable. Bread choice matters too; a sturdy, rustic loaf holds up perfectly to the toppings and toasting without getting soggy.

• 1 baguette or rustic bread loaf, sliced about 1/2 inch thick
• 2 cups sliced cremini or button mushrooms
• 3 cloves garlic, minced
• 1 cup shredded mozzarella cheese
• 1/2 cup grated Parmesan cheese
• 2 tablespoons unsalted butter
• 1 tablespoon olive oil
• 1 teaspoon fresh thyme leaves or 1/2 teaspoon dried thyme
• Salt and freshly ground black pepper, to taste
• Optional: chopped fresh parsley for garnish

If you’re short on mozzarella, feel free to substitute with provolone or fontina for a different but equally melty texture. For a dairy-free version, try a plant-based cheese and swap butter for olive oil.
