Preheat oven to 245°C.
02 -
In a 25 cm ovenproof skillet over medium-high heat, warm olive oil. Add sliced garlic and sauté until lightly golden, about 1 minute.
03 -
Add San Marzano peeled tomatoes carefully to the skillet. Mash with a potato masher or the back of a wooden spoon. Cook for 1 minute, reducing heat as necessary to avoid burning garlic.
04 -
Add fresh spinach and rinsed Cannellini beans to the skillet. Sprinkle in Italian seasoning, crushed red pepper flakes, kosher salt, and black pepper. Stir well until spinach is slightly wilted and ingredients are evenly combined.
05 -
Evenly distribute shredded mozzarella over the mixture.
06 -
Transfer the skillet to the preheated oven. Bake for 8–10 minutes, until cheese is melted and beginning to brown in spots.
07 -
For additional browning, switch oven to broiler setting and broil for up to 2 minutes, watching closely.
08 -
Remove from oven and serve immediately, ideally with tortilla chips.
