Vegetarian Lemon & Olive Oil White Sweet Potato Mash
White sweet potatoes have a creamier, more delicate flavor than their orange cousins, and mashing them with good olive oil instead of butter or cream lets that natural sweetness really shine. A quick bloom of garlic, turmeric, and ginger in the skillet before folding everything together gives this mash a warmth and depth that feels anything but plain. The bright hit of fresh lemon juice and zest at the end cuts through the richness and keeps every bite lively. Because the whole dish is built on olive oil rather than dairy, it sidesteps the usual concern about whether a creamy side dish is truly meat-free and butter-free — no substitutions needed, just genuinely clean ingredients from the start. Finishing with a drizzle of extra-virgin olive oil and a scatter of fresh parsley makes it look as good as it tastes. This is the kind of effortless, crowd-pleasing side that earns a permanent spot on your weeknight rotation.

4 servings
- 2 lb white sweet potatoes, peeled and cut into 1 ½-inch chunks
- 1 tsp fine sea salt, plus more for the cooking water
- 3 tbsp extra-virgin olive oil, plus more for drizzling
- 2 cloves garlic, minced
- ¼ tsp ground turmeric
- ¼ tsp ground ginger
- 2 tbsp fresh lemon juice (from about 1 lemon)
- 1 tsp lemon zest
- 2 tbsp fresh parsley, finely chopped (optional)
Instructions
- 1
Place the white sweet potato chunks in a large pot and cover with cold water by at least 1 inch. Add a generous pinch of salt. Bring to a boil over high heat, then reduce to a steady simmer and cook until the potatoes are completely tender and a fork slides through without resistance, 18–22 minutes.

While the potatoes cook, heat 1 tbsp of the olive oil in a small skillet over medium-low heat. Add the minced garlic and cook, stirring frequently, until softened and fragrant but not browned, about 1–2 minutes. Stir in the turmeric and ginger and cook for 30 seconds more, until the spices are fragrant. Remove from heat.
