Ingredients
Mashed Potatoes
- 800 g Yukon Gold potatoes, baked
- 2 heads roasted garlic, squeezed
- 100 ml heavy cream
- 60 g butter
Topping
- 2 whole split beef marrow bones
- 2 sprigs rosemary
Garnish
- 1/4 cup parsley-caper gremolata, for serving
- 1/2 tsp flaky salt, for serving
Why this recipe works
The method of using a potato ricer is essential for achieving the light, lump-free texture required for this dish. By ricing the potatoes while warm, you ensure that the starch granules are broken down uniformly without becoming overworked or gummy. Incorporating the roasted garlic directly into the hot mash allows the sweet, caramelized flavors to permeate throughout, creating a consistent base that provides the perfect canvas for the intense richness of the marrow.
Roasting the marrow bones at a high temperature ensures the fat renders completely, turning into a liquid gold consistency that folds effortlessly into the potatoes. Broiling the finished dish adds a crucial Maillard reaction on the surface of the potatoes, providing a pleasant contrast between the creamy interior and the slightly crisp, charred exterior.
This dual-temperature approach—first roasting for flavor development and then broiling for texture—is what separates this dish from standard mashed potato preparations.
Notes and substitutions
When selecting potatoes, Yukon Golds are the preferred choice due to their medium starch content, which provides a buttery flavor and a smooth, creamy finish. If you cannot find Yukon Golds, you may use Russets, though the texture will be slightly more starch-forward and less naturally buttery. Ensure you roast the garlic heads until they are deeply caramelized and soft; this sweetness is necessary to balance the savory, fatty profile of the beef marrow.
For the equipment, a cast iron skillet is highly recommended as it retains heat exceptionally well and is safe for the broiler. If you do not have a skillet, a shallow ceramic baking dish will work, though it will not provide the same heat retention.
The parsley-caper gremolata is a non-negotiable component for the final garnish, as the acidity from the capers and the freshness of the parsley cut through the richness of the marrow, preventing the dish from feeling overly heavy.
- Yukon Gold potatoes: Russet potatoes for a fluffier texture or fingerlings for extra creaminess.
- Heavy cream: Whole milk or half-and-half if a lighter consistency is desired.
