Add the olive oil and 1 Tablespoon of butter to a large cast iron skillet over medium high heat. Once hot, add the potatoes and allow to cook for 1-2 minutes without stirring to create a crust. Continue cooking for 5-6 minutes or until potatoes are browned and fork-tender. Add three cloves of garlic, 1 teaspoon rosemary, 1 teaspoon of thyme, salt and pepper to taste and continue cooking for 1-2 minutes until soft and fragrant. Remove the potatoes to a separate plate or paper towel.
