Begin by washing and peeling the potatoes. Cut them into even cubes and place them in a large pot. Cover with cold water, add salt, and bring to a boil. Cook until fork-tender, about 15-20 minutes.

Drain the potatoes and return them to the pot. Add minced garlic, butter, salt, pepper, and mash until smooth. Stir in cheddar cheese until melted. Spread the mixture into the greased baking dish and bake in the preheated oven for 20 minutes, or until golden brown on top.

Serve your cheesy garlic potatoes hot, garnished with fresh chives or parsley for an extra touch. Pair it with grilled meats or a fresh salad. Store any leftovers in an airtight container in the fridge for up to 3 days and reheat in the oven for best results.
