This smooth purée combines the earthy sweetness of parsnips and carrots with the slightly peppery bite of purple-top turnips. Caramelized shallots and a touch of fresh thyme add depth and freshness. The result is a refined, velvety side that complements roasted meats and holiday mains.

Print Recipe

• 6 large shallots, chopped
• 4 tablespoons butter, divided
• 1/2 teaspoon sugar
• 1 lb purple-top turnips, peeled and cut into 1-inch pieces
• 1 lb parsnips, peeled and cut into 1-inch pieces
• 1/2 lb carrots, peeled and cut into 1-inch pieces
• 1/4 cup cream or half-and-half
• 2 tablespoons fresh thyme leaves
• Pinch of nutmeg
• Salt and freshly ground pepper to taste

• Heat 2 tablespoons of butter in a skillet over medium-low heat. Add the chopped shallots and cook until they soften and become fragrant, about 4 minutes.
• Sprinkle in the sugar, season with a little salt and pepper, and continue cooking until the shallots turn golden and caramelized, about 6 more minutes. Remove from heat and set aside.
• Place approximately 1 inch of water in a large pot fitted with a steamer rack and bring to a boil. Add the carrots first, then add the turnips to the rack above the water.
• Cover and steam the vegetables for 4 minutes, then add the parsnips to the rack. Continue steaming until all the vegetables are tender when pierced with a knife, approximately 4 to 6 additional minutes.
• Transfer the steamed vegetables to a large bowl. Add the remaining 2 tablespoons of butter and the cream or half-and-half. Mash lightly with a large fork to break them up.
• Blend the mixture to a smooth, silky purée using an electric hand blender, food processor, or countertop blender, working in batches if necessary.
• Fold in the caramelized shallots with their butter, the fresh thyme leaves, a pinch of nutmeg, and salt and freshly ground pepper to taste. Adjust seasoning as needed.
• Transfer the purée to a warm serving dish and garnish with a small sprig of fresh thyme if desired. Serve hot alongside roasted meats or as part of a seasonal vegetable selection.
• To make ahead: Prepare the recipe completely and transfer to a buttered casserole. Refrigerate for up to 2 days. Cover tightly and reheat in a 325°F oven until warmed through, about 30 to 45 minutes.

Parsnips cook faster than carrots or turnips, so add them later in the steaming process to ensure even tenderness. If you substitute rutabaga for turnips, be aware rutabaga typically requires a slightly longer cooking time; adjust steaming until fork-tender.

When puréeing, aim for a smooth, silky texture rather than an ultra-thin consistency. If the mixture seems too thick, add a little more cream or a splash of warm stock to loosen it. Taste and correct the seasoning after blending since cold ingredients can mute flavors.

Caramelized shallots bring a sweet, savory depth—don’t rush this step. Cooking them slowly over medium-low heat develops their sugars and gives the purée a richer, more complex flavor.

Serving suggestions: This purée is a classic accompaniment to roasted poultry and pork. It also works well with pan-seared fish or as a bed for braised meats. For presentation, spoon into a warmed bowl and top with a few reserved caramelized shallots and a sprinkle of thyme.

Storage and reheating: Store leftovers in an airtight container in the refrigerator for up to 2 days. Reheat gently in a low oven or on the stovetop over low heat, stirring occasionally and adding a little cream or butter to refresh the texture. Avoid high heat, which can dry out the purée.

Variations: For a dairy-free version, substitute a plant-based cream and use olive oil or a dairy-free butter alternative. For extra richness, stir in a small knob of additional butter just before serving.
