Preheat your oven to 425°F to get it ready for baking.
Wash the mini potatoes thoroughly, scrubbing them clean, and slice each one in half. Set the potatoes aside.
In an 8x8-inch baking dish, combine the melted butter, garlic powder, Italian seasoning, and ⅓ cup of the grated Parmesan cheese. Stir the mixture with a fork until it forms a cohesive paste.
Add the potato halves to the baking dish, tossing them until they are completely coated in the butter and cheese mixture.
Sprinkle the remaining ¼ cup of Parmesan cheese evenly over the top of the potatoes.
Place the dish in the oven and bake for 35 to 45 minutes, depending on your preference for crispiness and golden color.
Once baked to perfection, remove the dish from the oven and serve the potatoes immediately.
Any leftovers can be stored in an airtight container in the refrigerator for up to one week. Reheat them in the oven or microwave as desired. Enjoy your delicious creation!
