In a large resealable plastic bag, combine 1/3 cup of cornstarch, 3/4 teaspoon of salt, 1/2 teaspoon of dried marjoram, 1/8 teaspoon of black pepper, and 1/2 teaspoon of dried thyme. Seal the bag and shake it gently to mix the seasonings.

Add the peeled and cubed potatoes into the plastic bag with the seasoning mixture. Seal the bag tightly, then shake it vigorously to coat the potatoes evenly with the seasoned flour mixture.

Preheat your oven to 450°F (232°C). Pour 1/4 cup of melted butter into a 13-inch x 9-inch baking dish, then stir in the minced garlic to infuse the butter with flavor.

Once the butter and garlic are combined, add the seasoned potatoes from the plastic bag into the baking dish. Spread them out evenly in a single layer. Place the bay leaf among the potatoes for added flavor.

Cover the baking dish with aluminum foil and place it in the preheated oven. Bake for 20 minutes to allow the potatoes to start cooking and absorb the flavors.

After 20 minutes, remove the foil from the baking dish and give the potatoes a gentle stir to ensure they cook evenly and brown on all sides.

Place the baking dish back into the oven, uncovered, and continue baking for an additional 15-20 minutes. This allows the potatoes to become crispy and lightly browned.

After 15-20 minutes, check the potatoes to ensure they are tender and golden brown. If needed, bake for a few more minutes until they reach your desired level of crispiness.

Once the potatoes are cooked to perfection, discard the bay leaf. Serve the crispy potato cubes hot as a delicious side dish or snack. Enjoy the crispy exterior and fluffy interior of these flavorful potatoes!
