Ingredients
How to Make It
Step 1
Adjust rack to top position (top and middle positions for 4 servings) and preheat oven to 450 degrees. Wash and dry produce.
Halve, peel, and thinly slice onion. Trim and thinly slice mushrooms (skip if your mushrooms are pre-sliced!).
Slice bacon* crosswise into ½-inch pieces.
Step 2
Heat a large drizzle of oil in a large, preferably nonstick, pan over medium-high heat. Add onion, mushrooms, and bacon; cook, stirring occasionally, until veggies are tender and bacon is browned and crispy, 5-7 minutes. TIP: Drain any excess grease from pan if desired.
Add ¼ cup water and 1 tsp sugar (½ cup water and 2 tsp sugar for 4 servings); cook, stirring occasionally, until onion is caramelized and mushrooms are tender, 1-2 minutes more. Season with salt and pepper.
Step 3
Place flatbreads upside down (dimpled sides down) on a baking sheet. Drizzle both sides of each flatbread with olive oil; brush or rub to coat all over, then season with salt and pepper. Toast on top rack until golden brown, 3-5 minutes. (For 4, divide flatbreads between two baking sheets; toast on top and middle racks, swapping rack positions halfway through.) Carefully flip flatbreads (dimpled sides up); sprinkle evenly with mozzarella. Top with bacon and veggies. Return to top rack; bake until cheese melts and flatbreads are crispy, 3-4 minutes. (For 4, return to separate racks, swapping positions halfway through.)
Return to top rack; bake until cheese melts and flatbreads are crispy, 3-4 minutes. (For 4, return to separate racks, swapping positions halfway through.)
Step 4
Slice bacon and mushroom flatbreads into pieces.
Divide between plates and top with as much hot sauce as you like. Serve.
