Ingredients
For the Flatbread
1 artisan flatbread or naan (10–12 inches)
2 tablespoons olive oil
1 tablespoon butter
8 ounces cremini mushrooms, sliced
1 large sweet onion, thinly sliced
2 cloves garlic, minced
1 teaspoon fresh thyme leaves
½ teaspoon kosher salt
¼ teaspoon black pepper
1 cup shredded mozzarella cheese
½ cup shredded fontina cheese
¼ cup grated Parmesan cheese
Finishing Ingredients
2–3 tablespoons Heat Street Detroit Green Michigan Tomatillo Verde Hot Sauce
2 tablespoons chopped fresh parsley
1 tablespoon chopped cilantro
Zest of ½ lime
Optional: crumbled goat cheese or feta for extra tang
Instructions
Caramelize the Onions
Heat a large skillet over medium heat with the olive oil and butter. Add the onions with a pinch of salt and cook for 12–15 minutes, stirring occasionally, until deeply golden and sweet.
Cook the Mushrooms
Add the mushrooms to the skillet. Cook 6–8 minutes until browned and their moisture has evaporated. Stir in the garlic, thyme, black pepper, and cook for 1 additional minute.
Flavor Profile
Savory, earthy, cheesy, and slightly sweet with a bright, tangy finish. Caramelized onions bring natural sweetness, browned mushrooms add deep umami flavor, and mozzarella, fontina, and Parmesan create a rich, creamy layer. Green Michigan Tomatillo Verde Hot Sauce adds fresh tomatillo, lime, cilantro, and jalapeño flavor for a vibrant finish with just the right amount of heat.
Why This Recipe Works
Rich cheese, earthy mushrooms, and sweet caramelized onions need something fresh and acidic to balance them—and that’s where Green Michigan shines. The tangy tomatillo and lime cut through the richness of the melted cheese, while jalapeño adds a gentle heat and cilantro brings a fresh, herbaceous finish.
Drizzling the hot sauce over the flatbread after baking keeps its bright Verde flavors front and center, creating a delicious contrast between the warm, savory toppings and fresh, zesty heat.
Heat Street Tip
Add Green Michigan Tomatillo Verde Hot Sauce **after the flatbread comes out of the oven** to keep its fresh tomatillo, lime, cilantro, and jalapeño flavors bright and vibrant. Start with a generous drizzle, then serve extra on the side for anyone who wants to turn up the Verde heat.
