Smashed Potatoes with Roasted-Garlic Gravy

These smashed potatoes with roasted-garlic gravy represent the ultimate comfort food side dish. By coarsely mashing the potatoes with a blend of butter and extra-virgin olive oil, you achieve a rustic texture that perfectly catches the rich, velvety sauce. The gravy itself is the star of the show, built from a deeply flavoured homemade vegetable stock and enriched with sweet, caramelised roasted garlic cloves for an incredible depth of flavour.

This vegetarian dish is a sophisticated alternative to traditional mash and gravy, making it an excellent choice for a Sunday roast or a festive centrepiece. While the stock takes a little time to simmer, the results are far superior to shop-bought versions, offering a savoury complexity that tastes wonderful alongside seasonal roasted vegetables or your favourite meat-free roast.

How to make Smashed Potatoes with Roasted-Garlic Gravy

Preheat oven to 204°C.

Separate 6 cloves from garlic (do not peel), drizzle with a little olive oil, and double-wrap tightly in foil. Roast until garlic is very soft, about 45 minutes.

While garlic roasts, heat oil (2 tablespoons ) in a 4-to 5-quart heavy pot over medium heat until it shimmers, then cook vegetables, remaining garlic cloves (separated but not peeled), bay leaf, and peppercorns, stirring occasionally, until browned, about 8 minutes. Stir in wine and boil until most has evaporated. Add soy sauce and water and simmer, uncovered, 30 minutes.

Strain stock through a fine-mesh sieve into a large measuring cup. If you have more than 950ml , boil to reduce; if less, add water.

Unless they are very small, cut potatoes (peeled if desired) into 2-inch pieces. Generously cover with cold water in a 5-quart saucepan and add 2 teaspoons salt. Simmer, uncovered, until just tender, 12 to 15 minutes. Reserve 80ml cooking liquid and stir butter and oil into it. Drain potatoes, then return to pan along with reserved liquid and coarsely mash. Season with salt and pepper and keep warm, covered.

Mash roasted garlic to a purée.

Melt butter in a heavy medium saucepan over medium heat. Stir in flour and garlic purée and cook, stirring, 2 minutes. Slowly add stock, whisking, then simmer 3 minutes. Season with salt and pepper.
