Walnut Free Lemon & Olive Oil Root Vegetable Mash
This vibrant root vegetable mash is the kind of side dish that quietly steals the show at the dinner table. Parsnips, sweet potato, and turnips are boiled until silky-tender with smashed garlic, then mashed together with warm, spice-infused olive oil, bright lemon juice, and a hit of zest that makes the whole bowl sing. The turmeric and ginger add a gentle warmth and a gorgeous golden hue without overpowering the natural sweetness of the vegetables. Letting the steam escape before mashing is a smart little trick that keeps the texture luxuriously creamy rather than watery or dense. A final drizzle of olive oil and a scatter of fresh parsley make it look as good as it tastes. It's completely free of tree nuts by nature — no substitutions needed, no label-checking required, just wholesome produce and pantry staples doing all the work. Serve it alongside roasted meats, grilled fish, or a hearty grain bowl for a comforting, crowd-pleasing finish.

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.
