Refrigerator: Store any leftovers in an airtight container for up to 3-4 days. The beans absorb more sauce as they sit, so they’re actually delicious the next day.
Reheating: Reheat in the microwave or on the stove. For the best result, reheat in the oven with a splash of water and add a little extra mozzarella on top for a fresh melted cheese layer.
Freezer: Freeze the bean and sauce mixture (without the cheese) for up to 3 months. Defrost, reheat, add fresh mozzarella, and grill.
Expert Tips for the Best Pizza Beans!
Use pizza sauce, not passata: If you can find it, pizza sauce is thicker and already seasoned with herbs and garlic. It gives you that more concentrated pizza flavor with less work and way more flavor. I used the Mutti pizza sauce, which has basil and oregano in it - simmered for 10 minutes- and you’ve got the perfect thick sauce for the white beans. If you can’t find pizza sauce, try using a basil tomato pasta sauce and follow the same instructions to simmer it low and slow with the white beans.
Use an oven-proof skillet: Since the final step is grilling, you need a pan that can go under the grill. Cast iron is ideal - it retains heat and keeps the beans bubbling at the table. If your pan isn’t oven-proof, transfer to a baking dish before adding the cheese.
Low-moisture mozzarella for the best melt: The shredded, bagged mozzarella browns and melts more evenly than fresh. Fresh mozzarella is lovely but releases a lot of water, which can make the top soggy rather than golden, and can turn rubbery when grilled rather than having that lovely stretchy, melty texture.
