Mustard Free Lemon & Olive Oil White Sweet Potato Mash
White sweet potatoes have a creamier, more delicate flavor than their orange cousins, and this mash lets them truly shine. Blooming garlic, turmeric, and ginger in warm olive oil before folding them in is the kind of small step that makes a big difference — the spices open up and weave through every bite rather than sitting on top. A hit of fresh lemon juice and zest keeps the whole dish bright and lively, cutting through the richness of the extra-virgin olive oil in the best possible way. Every ingredient here is straightforward and naturally free of mustard in any form, so there's no need to scrutinize labels or worry about hidden condiment derivatives sneaking into your side dish. The technique of letting the drained potatoes steam off for a minute or two before mashing is a small but smart move that keeps the texture silky rather than watery. Finished with a drizzle of olive oil and a scatter of fresh parsley, it's the kind of elegant, crowd-pleasing side that looks like you put in far more effort than you actually did.

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.
- 2
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.
