Equipment

1 9x13 inch baking dish or casserole dish
1 kitchen scissors (optional but makes cutting the biscuits easier than using a knife in my experience)

Ingredients

16 ounce can refrigerated biscuit dough I use Pillsbury Grands Butter Tastin Flaky Layers, 8 count
1 ½ cups pizza sauce (or marinara sauce)
2 cups shredded mozzarella cheese or more if desired, to taste
1 teaspoon Italian seasoning
20 pepperoni slices approximately, or as desired

Instructions

Preheat oven to 375F and spray a 9x13-inch baking dish with cooking spray or grease the pan. Tip - I recommend using a porcelain or glass baking dish intended for casseroles rather than a metal pan (which will cause the dough to cook faster which can increase the chances for burning).
Open the can of biscuit dough (pop!), separate the biscuits, and cut each of the biscuits into 8 pieces. So you'll have approximately 64 pieces of dough. Scatter them evenly in the bottom of the prepared baking dish. Tip - I find it easier to use a kitchen scissors than a knife to cut the biscuits but it's up to you.
Evenly pour the pizza or marinara sauce over the dough.
Evenly scatter the shredded cheese, sprinkle with Italian seasoning, and add the pepperoni.
Bake for about 30-40 minutes, or until the biscuits are golden brown and cooked through in the center. Tip - If the top of the bubble up is browning too quickly after about 20 minutes but you suspect the biscuits aren't close to being fully cooked, cover the baking dish with a sheet of foil for the remainder of the cooking time. Serve warm and fresh.

Notes

Storage: Leftovers will keep airtight in the fridge for up to 5 days noting that this is one of those recipes that's at its peak when it's warm and freshly made. While I haven't frozen leftovers, I'm sure you could for up to 3 months. Reheat leftovers very gently in the microwave.
