Spinach Salad with Roasted Sweet Potato and Sunflower Seeds

A vibrant, satisfying green salad built on tender baby spinach with cubes of caramelized roasted sweet potato, toasted sunflower seeds, and thin red onion slices. A warm honey-mustard vinaigrette brings everything together with just enough acidity and warmth to complement the natural sweetness of the roasted potato. This salad works equally well as a side dish or a light main course.

Steps

Before you start
  • Preheat your oven to 425°F (220°C)
  • Line a baking sheet with parchment paper
  • Bring out any chilled ingredients 10 minutes before assembly so they reach room temperature
  1. Toss and season sweet potato

    • On the prepared baking sheet, combine the cubed sweet potato with 2 tbsp olive oil, ½ tsp kosher salt, ¼ tsp black pepper, and ½ tsp smoked paprika (if using).
    • Toss until every piece is evenly coated.
    • Spread in a single layer.

    Ready when: all pieces coated evenly

    Tip: Don't skip the paprika—it adds subtle depth and a hint of smokiness that complements the natural sweetness of the potato.

  2. Roast sweet potato cubesOven 425°F / 220°C

    • Place the baking sheet in the preheated 425°F (220°C) oven.
    • Roast for 20–22 minutes, stirring halfway through at the 10-minute mark.
    • The cubes are done when the edges are caramelized (slightly darkened and crispy) and the centers are tender when pierced with a fork.

    Ready when: edges are caramelized and golden, centers are fork-tender

    Tip: Stirring halfway prevents uneven cooking and helps achieve even caramelization on all sides.

  3. Toast sunflower seeds

    • While the sweet potato roasts, place the sunflower seeds in a dry skillet over medium heat.
    • Toast, stirring frequently, for 3–4 minutes until fragrant and lightly browned.
    • Transfer to a plate to cool slightly.

    Ready when: seeds are fragrant and light golden brown

    Tip: Toasting brings out the seeds' nutty flavor and makes them crispier. Keep your ear tuned—they toast quickly and can burn if left unattended.

  4. Make the vinaigrette

    • In a small bowl, whisk together 1 tbsp Dijon mustard, 1 tbsp honey, and 2 tbsp red wine vinegar until combined.
    • Slowly drizzle in 3 tbsp extra-virgin olive oil while whisking constantly to emulsify.
    • Season with ¼ tsp kosher salt and black pepper to taste.
    + Show details

    Ready when: dressing is smooth, slightly thickened, and unified in color

    Tip: Whisking in the oil slowly creates an emulsion that holds the vinaigrette together. If it breaks or separates, whisk in a teaspoon of warm water.

  5. Assemble the salad

    • Place the rinsed and dried baby spinach in a large mixing bowl.
    • Add the thin-sliced red onion.
    • Drizzle with about three-quarters of the vinaigrette and toss gently until the spinach is lightly coated but not soaked.
    • The spinach should still look fresh and vibrant, not wilted.
    + Show details

    Ready when: spinach is lightly coated, still crisp and bright green

    Tip: Don't over-dress—you want the spinach to stay tender and crisp. Reserve extra dressing on the side for anyone who wants more.

  6. Top and serve

    • Divide the dressed spinach among four serving plates or bowls.
    • Top each portion with a generous handful of the roasted sweet potato cubes and a sprinkle of the toasted sunflower seeds.
    • Drizzle any remaining vinaigrette over the top.
    • Serve immediately while the sweet potato is still warm.

    Ready when: salad is composed and ready to eat

    Tip: The warmth of the roasted sweet potato gently wilts the spinach just enough without making it mushy—this contrast is what makes the salad special.

Good to know

Tips
  • To prevent the spinach from wilting before service, keep it separate from the dressing until just before plating. The warm sweet potato will gently soften the leaves without turning them mushy.
  • If you prefer a creamier dressing, whisk in 1 tablespoon of Greek yogurt or crème fraîche into the vinaigrette. This also adds body and makes the dressing cling better to the greens.
  • For extra protein and richness, top each serving with a soft-boiled egg, crumbled feta cheese, or grilled chicken breast. The warm roasted potato and creamy egg yolk pair beautifully.
  • Slice the red onion as thin as possible—use a mandoline or a very sharp knife—to keep the bite and color vibrant without overwhelming the tender spinach.
Make ahead

The roasted sweet potato and toasted sunflower seeds can be prepared up to 8 hours ahead and stored separately in airtight containers. The vinaigrette can be made 1 day ahead and refrigerated. The spinach should be rinsed and dried just before assembly. Toss the salad no more than 5 minutes before serving to keep the spinach crisp.

Storage & reheating

Store leftover roasted sweet potato and seeds separately from the dressed salad. The sweet potato keeps in an airtight container in the refrigerator for up to 4 days and can be reheated gently in a 350°F oven for 5 minutes. Undressed spinach and red onion last 2–3 days refrigerated. Do not store a fully dressed salad, as the spinach will wilt.

Substitutions
  • Red wine vinegar → Apple cider vinegar or white wine vinegar. Both offer similar acidity and brightness. Use the same amount. Apple cider is slightly sweeter and fruitier.
  • Raw sunflower seeds → Pumpkin seeds (pepitas), sliced almonds, or walnuts. Any will add crunch and nutritional depth. Use the same volume (½ cup). Toast them the same way if raw.
  • Smoked paprika → Regular paprika, ground cumin, or ¼ tsp cayenne pepper. Paprika adds color; cumin adds earthiness; cayenne adds heat. All are optional but recommended.
  • Red onion → Thinly sliced white or yellow onion, or shallot. Red onion's color and mild bite are ideal, but others work. Shallots are sweeter and more delicate.
