Butternut Squash Pizza with Prosciutto and Caramelized Onions Directions

Roast Butternut Squash

1. Preheat your oven to 425 degrees Fahrenheit. We use the same temperature if we’re cooking inside in the oven or in an outdoor pizza oven.
2. In a large bowl, place the pieces of butternut squash and season with olive oil, salt, and pepper. Toss to combine. Place on a baking sheet and bake for 15 -20 minutes, or until tender and soft. There will be some slight browning. Remove from the oven and set aside for the pizza.

Caramelize Onions

1. Cut one small red onion into thin slices. Add butter and olive oil to a large cast-iron skillet over medium heat. Stir occasionally until the onions are dark in color. Add a touch of kosher salt. This should take about 30 minutes.

Make Pizza (Pizza Oven Instructions)

1. Prepare your pizza oven and get the pizza stone to 700 – 750 degrees Fahrenheit.
2. Sprinkle flour on a large cutting board or wooden pizza peel. Roll out the pizza into a 12-inch round by hand. Do not use a rolling pin.
3. Mix the olive oil and garlic in a small bowl and set aside.
4. Transfer the pizza to a peel and then brush the base with garlic oil within 1″ of the rim, then layer with mozzarella cheese, roasted butternut squash cubes, caramelized onions, prosciutto, and sage.
5. Launch the pizza into the pizza oven using your pizza peel. Use the turning peel to rotate the pizza every 15 seconds or until you see the crust brown. Continue to rotate the pizza until it's cooked all the way through. It should take 90 seconds to 2 minutes to cook the pizza in an outdoor pizza oven.
6. Remove and place on a cutting board. Slice into wedges and serve. Add any finishing drizzle, such as Maldon salt, hot honey, or aged balsamic vinegar.
