Lupin Free Lemon & Olive Oil Root Vegetable Mash
Creamy, golden, and brightened with lemon, this root vegetable mash is the kind of side dish that quietly steals the show at the dinner table. Parsnips, sweet potato, and turnips are simmered together until completely tender, then mashed with warm olive oil infused with turmeric and ginger — the result is silky, fragrant, and deeply satisfying. A squeeze of fresh lemon juice and a hit of zest lift the whole thing, keeping it from feeling heavy despite how comforting it is. Because the recipe relies entirely on whole vegetables, olive oil, and spices, there are no hidden fillers or flour-based thickeners to worry about — it's naturally free of the legume-related ingredients that can sneak into processed or restaurant versions of mashed sides. Letting the vegetables steam dry before mashing is a small but smart step that makes a real difference in texture, giving you a smooth, creamy finish rather than a watery one. A final drizzle of good olive oil and a scatter of fresh parsley make it look as good as it tastes. Whether you're serving it alongside a roast or making it the centerpiece of a lighter meal, this mash is simple enough for a weeknight and impressive enough to bring to a table full of guests.

4 servings
- 2 medium parsnips (about 12 oz total), peeled and cut into 1-inch chunks
- 1 medium sweet potato (about 10 oz), peeled and cut into 1-inch chunks
- 2 medium turnips (about 10 oz total), peeled and cut into 1-inch chunks
- 1 tsp fine sea salt, plus more to taste
- 3 tbsp extra-virgin olive oil, plus more for drizzling
- 2 tbsp fresh lemon juice (from about 1 lemon)
- 1 tsp lemon zest
- ¼ tsp ground turmeric
- ¼ tsp ground ginger
- 2 cloves garlic, peeled and smashed
- 2 tbsp fresh flat-leaf parsley, finely chopped (optional)
Instructions
- 1
Place the parsnips, sweet potato, turnips, and smashed garlic cloves in a large pot. Cover with cold water by at least 1 inch and add 1 tsp fine sea salt. Bring to a boil over high heat, then reduce to a steady simmer and cook until all the vegetables are completely tender and a fork slides through without resistance, about 20–22 minutes.
- 2
Drain the vegetables through a colander, then return them to the warm pot. Let them sit uncovered for 1–2 minutes so residual steam can escape — this prevents a watery mash.
