The truly genius element of this pizza isn’t its cheesy layers of fresh parmesan and mozzarella. Or the hot Italian sausage that gets baked in bubbling tomato sauce until it’s crispy on top, but still juicy inside. Or even the thin fennel slices that fan out across the top, creating a frond-like pattern and adding a hint of sweetness. No, what sets this mouthwatering grandma-style pizza apart from others is the fact that you can freeze it right in the sheet tray it’s made in, for up to one month. That’s right, DIY frozen pizzas. The recipe makes two full sheet trays, so you might want to bake one off the night you make it—and save the other for a night when you want to put dinner on the table in 10 minutes.
