Preheat the oven to 425°F.
Heat the olive oil in a large oven-safe sauté pan over medium-high heat.
Once the oil is hot, add the onion and sauté until slightly translucent, 1 to 2 minutes. Add the garlic and sauté for another 30 seconds to 1 minute, or until fragrant.
Pour in the Marinara, Calabrian chili paste, Italian seasoning, dried oregano, sugar, ½ teaspoon salt, and ½ teaspoon pepper, mixing to combine.
Add the navy beans, mixing to coat.
Sprinkle the mozzarella over the top of the beans in an even layer, followed by your toppings of choice.
Cover the pan with a lid or tightly with foil and bake until the cheese has melted, 10 to 15 minutes.
Remove the lid and place the pan under the broiler on the low setting, until the cheese is golden and bubbly, 3 to 5 minutes. Make sure to watch it closely so it doesn’t burn.
Garnish with Parmesan and basil, and enjoy!
