Ingredients
Gather these ingredients to make your Garlic Parmesan Duchess Potatoes:
For the Potatoes:
- 2 pounds russet potatoes, peeled and cut into chunks
- 2 tablespoons unsalted butter
- 2 tablespoons heavy cream
- 1 teaspoon garlic powder (or 2-3 cloves fresh garlic, minced)
- ½ cup grated Parmesan cheese
- 1 large egg, beaten
- Salt and pepper, to taste
For the Topping (optional):
- Fresh parsley, finely chopped (for garnish)
- Additional grated Parmesan cheese (for sprinkling)
Ingredient Highlights
- Russet Potatoes: The starchy variety perfect for mashing, ensuring a smooth and fluffy interior.
- Garlic Powder/Fresh Garlic: Provides a delicious garlic flavor that complements the potatoes perfectly.
- Parmesan Cheese: Adds a savory, umami depth to the potatoes, giving them a rich, cheesy flavor.
- Heavy Cream and Butter: These ingredients ensure the potatoes are creamy and smooth.
- Egg: Used to bind the mixture together and help form the crisp exterior when baked.
Step-by-Step Instructions
Here’s how to make Garlic Parmesan Duchess Potatoes:
Prepare the Potatoes:
- Cook the Potatoes: In a large pot, bring the peeled and cut potatoes to a boil in salted water. Cook for about 15-20 minutes or until tender when pierced with a fork.
- Drain and Mash: Drain the cooked potatoes well and return them to the pot. Mash them using a potato masher or a ricer for a smoother texture.
Make the Potato Mixture:
- Add the Flavorings: To the mashed potatoes, add the butter, heavy cream, garlic powder (or minced fresh garlic), grated Parmesan cheese, and a pinch of salt and pepper. Stir until well combined and creamy.
- Incorporate the Egg: Add the beaten egg to the mixture and stir until smooth. The egg will help bind the potatoes together and create a nice texture when baked.
Pipe the Potatoes:
- Prepare the Baking Sheet: Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
- Pipe the Potatoes: Transfer the potato mixture to a piping bag fitted with a large star tip (or you can use a zip-top bag with the tip cut off). Pipe the potatoes onto the prepared baking sheet in small swirls, making sure to leave space between each one.
- Optional Topping: If desired, sprinkle additional grated Parmesan cheese on top of each swirl for extra flavor and a crispier crust.
Bake the Potatoes:
- Bake until Golden: Bake the potatoes in the preheated oven for 25-30 minutes or until the edges are golden brown and crispy, and the centers are fully set.
- Optional Garnish: After baking, garnish with fresh parsley and an extra sprinkle of Parmesan cheese for added flavor and color.

How to Serve
- With Steak or Chicken: These potatoes pair beautifully with grilled steak, roasted chicken, or any protein.
- For Special Occasions: Serve as a side for holiday dinners, birthday parties, or other formal events.
- With Roasted Vegetables: A great side dish to complement roasted vegetables like carrots, Brussels sprouts, or asparagus.
- With a Creamy Sauce: Pair with a creamy sauce like garlic butter or hollandaise for an extra layer of flavor.
Additional Tips
- If you don’t have a piping bag, you can spoon the potato mixture onto the baking sheet in mounds and create the swirl shape with a spoon or fork.
- For a smoother finish, use a potato ricer when mashing the potatoes.
- Make sure to let the mashed potatoes cool slightly before adding the egg to prevent curdling.
- If you want a more pronounced garlic flavor, feel free to add more garlic or use roasted garlic for a sweeter, milder taste.
