1-Getting started: Getting started with Garlic Parmesan Duchess Potatoes is straightforward and fun, even if you’re new to cooking. Begin by preheating your oven to 425 degrees Fahrenheit and lining a baking sheet with parchment paper for easy cleanup. This sets the stage for a crispy finish that everyone will love.

2-Cooking the potatoes: Next, place the diced potatoes in a large pot, cover them with cold water by 1 to 2 inches, and add 1 tablespoon salt to enhance the flavor. Bring the water to a boil, then lower the heat and simmer with the lid on until the potatoes are very tender, which takes about 15 to 20 minutes. Once done, drain them well to remove excess moisture.

3-Making garlic butter: While the potatoes cook, melt 4 tablespoons of the butter in a small saucepan over medium heat. Add the minced garlic and sauté it until it’s lightly golden and softened, about 1 to 2 minutes, then stir in 3 tablespoons of the half and half and move the mixture to a bowl to cool.

4-Mashing and mixing: In a large bowl, mash the potatoes until they’re smooth and lump-free using a masher or ricer. Mix in the parmesan cheese and the warm garlic butter mixture, then season with salt and pepper. Let it cool a bit before adding the 4 egg yolks one at a time. If the mix is too thick, add the extra tablespoon of half and half.

5-Piping and preparing for baking: Transfer the mixture to a piping bag with a large star tip that’s about 3/4 inch wide, and pipe it into 12 mounds on the baking sheet, each about 2 1/2 inches wide and tall. If you don’t have a piping bag, just spoon the mounds instead. Brush them with the remaining 2 tablespoons of melted butter for a golden touch.

6-Baking and serving: Finally, bake in the preheated oven for 16 to 19 minutes until they’re golden brown, then serve right away with parsley and extra parmesan if you like. This method creates that creamy texture with a rich flavor that makes the dish stand out. For another potato side idea, try our candied yams recipe.
