Step‑by‑Step Instructions for Garlic Parmesan Duchess Potatoes
Step 1: Roast the Garlic
Begin by preheating your oven to 180°C (356°F). Slice the tip off a bulb of garlic, drizzle olive oil over it, and wrap it tightly in foil. Place it in the oven and roast for 50-60 minutes until the garlic is golden brown and soft. Once roasted, allow it to cool slightly, then squeeze the cloves out and mash them into a smooth paste, ready to be mixed into the potatoes.
Step 2: Prepare the Potatoes
While the garlic cools, peel and dice 1.3kg (2.8lb) of baking potatoes into uniform chunks. Place them in a large pot of water with a generous sprinkle of salt and bring to a boil. Cook the potatoes until fork-tender, about 15-20 minutes. Once cooked, drain them thoroughly and return to the pot. Let them steam dry for about 5 minutes to eliminate excess moisture, ensuring a fluffy mash.
Step 3: Mash the Potatoes
Add the drained potatoes back into the pot and begin mashing them with 75g of butter, 2 tablespoons of double cream, and the roasted garlic paste. Mix until creamy and smooth, ensuring there are no lumps. Season generously with salt and pepper to enhance the flavors. Gradually stir in 4 egg yolks, one at a time, ensuring each yolk is fully incorporated before adding the next, which will help the Garlic Parmesan Duchess Potatoes hold their shape.
Step 4: Pipe the Potatoes
Prepare a baking tray by lining it with baking paper. Transfer the creamy potato mixture into a piping bag fitted with a large star tip. Pipe swirly dome shapes onto the tray, aiming for dimensions of about 2.5-3 inches wide and high. Take your time to create elegant, swirly mounds that look inviting, ensuring each one stands tall with a beautiful shape.
Step 5: Bake to Perfection
Once piped, drizzle melted butter over the tops of the potato mounds for an extra layer of richness. Preheat your oven again to 200°C (400°F) and bake the Garlic Parmesan Duchess Potatoes for 15-20 minutes, or until they turn golden brown and crispy on top. Keep a close eye on them during the last few minutes for an even bake, and enjoy the delightful aroma wafting through your kitchen!
