How to Make Potato Mousseline?

Follow these simple steps to craft a dish that’s as elegant as it is comforting.

Step 1: Roast the Garlic

Begin by roasting the garlic. Cut off the top of a garlic bulb to expose the cloves, drizzle with olive oil, and wrap it in foil. Roast it at 350°F for about 40 minutes until soft and golden. This step infuses the dish with a subtle, sweet garlic flavor.

Step 2: Boil the Potatoes

Peel and slice the potatoes, then boil them in salted water until fork-tender (around 10-15 minutes). Drain them well and allow them to cool slightly to avoid excess water in the final dish.

Step 3: Achieve a Smooth Texture

Pass the potatoes through a potato ricer or mash them using a masher. The key here is to eliminate any lumps, making the dish as smooth as possible.

Step 4: Blend the Ingredients

Squeeze the soft, roasted garlic into the mashed potatoes. Add warm cream, milk, and butter, and stir everything together until fully incorporated. Season with salt and pepper to taste. This is where the magic happens as the mixture becomes silky and rich.

Step 5: Bake to Perfection

Transfer the potato mixture into a greased baking dish. Smooth out the top for an even finish. Bake in the oven at 350°F for 30 minutes. If you like a golden crust, broil it for the last few minutes for an irresistible color and flavor.

Tips for Making the Recipe

To perfect your potato mousseline, follow these expert tips!

Use the Right Potatoes: Waxy potatoes won’t give you the right creamy texture. Opt for starchy varieties like Yukon Gold or Russets for the best results.
Warm the Cream and Milk: Cold liquids can make the texture uneven. Gently warming them before mixing will help create a smoother blend.
Don’t Overwork the Potatoes: Mixing too much can make them gluey, so fold the ingredients together gently for optimal texture.

Make Ahead and Storage

Potato mousseline is meal-prep-friendly and stores well.

If preparing in advance, transfer the cooked mixture to a baking dish, cover, and refrigerate for up to two days. When you’re ready to serve, bake it directly from the fridge until heated through. For freezing, allow the potatoes to cool completely before placing them in an airtight container or freezer bag. They can be stored for up to one month. Thaw them in the fridge overnight, then reheat in the oven, adding a splash of milk or cream to maintain moisture.

Potato mousseline is a true crowd-pleaser that adds elegance to any meal. Its simplicity and versatility make it an essential recipe for your repertoire. Once you try it, you’ll wonder why you didn’t make it sooner.
