Ingredients

Here’s what you’ll need for these Garlic Parmesan Duchess Potatoes:

  • 1 large bulb of Garlic
  • 1.3kg / 2.8lb Baking Potatoes
  • 5 tbsp / 75g Butter, (2 tbsp/30g melted, the rest left at room temp)
  • 2 tbsp Double / Heavy Cream, (at room temp)
  • 60g / 3/4 cup freshly grated Parmesan, (plus more to serve)
  • 4 large Egg Yolks
  • finely diced Fresh Parsley, (to serve)
  • Olive Oil, (as needed)
  • Salt & Pepper, (as needed)

How to Make Garlic Parmesan Duchess Potatoes

Step 1: Roast the Garlic

Start by preparing the garlic. Slice the tip off the garlic bulb to expose the cloves and drizzle with olive oil. Wrap it in foil and place it in the oven at 180C/356F for 50-60 minutes until very soft and golden. Allow it to cool slightly before squeezing out the garlic into a bowl. Sprinkle with salt and mash until smooth.

Step 2: Prepare the Potatoes

Peel and dice the baking potatoes into large pieces. Place them in a large pot filled with cold water and add 2 teaspoons of salt. Bring to a boil and cook until fork-tender, about 15-20 minutes. Drain them well and let them steam dry in a colander for about 5 minutes.

Step 3: Combine Ingredients

In the same pot, mash the drained potatoes together with 3 tablespoons of butter and heavy cream. Mix in the roasted garlic and freshly grated Parmesan cheese until smooth. Season generously with salt and pepper. Once slightly cooled, stir in each egg yolk one at a time until fully incorporated.

Step 4: Pipe the Potatoes

Transfer the mixture into a piping bag fitted with a large star tip. On a large baking tray lined with parchment paper, pipe swirls of potato mixture into dome shapes about 2.5-3 inches wide. You should yield around ten duchess potatoes.

Step 5: Bake Until Golden

Gently drizzle melted butter over each piped dome so that it coats evenly. Bake in an oven preheated to 200C/400F for about 15-20 minutes or until golden brown on top. Keep an eye on them as they can char quickly; turn the tray if necessary.

Step 6: Serve and Enjoy!

Once done, garnish your Garlic Parmesan Duchess Potatoes with finely chopped parsley and extra Parmesan cheese before serving warm. Enjoy this delightful dish!

How to Perfect Garlic Parmesan Duchess Potatoes

To create the best Garlic Parmesan Duchess Potatoes, follow these tips for a flawless result every time.

  • Choose the Right Potatoes: Opt for starchy baking potatoes like Russets for a fluffy texture.
  • Avoid Over-mashing: Mash until just smooth; over-mashing can make them gummy.
  • Cool Before Adding Eggs: Let the potato mixture cool slightly before mixing in egg yolks to prevent scrambling.
  • Pipe with Care: Use a piping bag to create beautiful shapes and ensure even cooking.
  • Watch While Baking: Keep an eye on them in the oven; they can brown quickly, so rotate the tray if necessary.

Best Side Dishes for Garlic Parmesan Duchess Potatoes

Garlic Parmesan Duchess Potatoes pair well with many dishes. Here are some fantastic side options that complement their rich, buttery flavor.

  1. Steamed Asparagus: Bright green asparagus adds a fresh touch and crunch.
  2. Honey Glazed Carrots: Sweetened carrots provide a nice contrast to savory potatoes.
  3. Creamed Spinach: A rich creamed spinach dish enhances the overall elegance of your meal.
  4. Sautéed Mushrooms: Earthy mushrooms bring depth and umami that pairs wonderfully with garlic flavors.
  5. Grilled Zucchini: Lightly grilled zucchini adds color and freshness while remaining low in calories.
  6. Roasted Brussels Sprouts: Crispy Brussels sprouts add texture and a slightly bitter flavor that balances richness.

Common Mistakes to Avoid

Making Garlic Parmesan Duchess Potatoes can be simple, but there are a few common pitfalls to avoid for the best results.

  • Skipping the garlic roasting: Failing to roast the garlic can result in a harsh flavor. Always roast the garlic until soft and caramelized for a sweeter taste.
  • Not mashing potatoes properly: Over-mashing or under-mashing can lead to a lumpy texture. Aim for a smooth consistency by mashing thoroughly but not excessively.
  • Incorrect seasoning: Neglecting to season your mash can leave it bland. Taste and adjust with salt and pepper throughout the process to enhance flavors.
  • Piping technique errors: Rushing the piping can result in uneven shapes. Take your time to create uniform swirls for even cooking and presentation.
  • Ignoring oven temperature: Baking at an incorrect temperature may lead to overcooked or undercooked potatoes. Monitor closely and adjust as needed for perfect browning.

Refrigerator Storage

  • Duration: Store in the refrigerator for up to 3 days.
