Ingredients

Units Scale

For the Warm Salad:

  • 2 whole sweet potatoes, peeled and cut into cubes
  • 2 whole zucchini, ends trimmed and cut into cubes
  • 1/2 cup baby carrots, sliced in half lengthwise
  • 4 oz fresh mushrooms, sliced in half
  • 6 oz broccoli florets
  • 1/2 cup olive oil
  • 1/2 tsp sea salt
  • 1/2 tsp black pepper
  • 2 cups quinoa, rinsed and dried; cooked according to package directions
  • 1/2 cup Feta Cheese, optional

For the Honey Dijon Vinaigrette:

  • 3/4 cup olive oil
  • 1/3 cup red wine vinegar
  • 1/2 tsp minced garlic
  • 1 tbsp honey
  • 2 tsp Dijon mustard
  • 1/4 tsp red pepper flakes
  • 1/2 tsp sea salt
  • 1 tsp black pepper

Instructions

  1. Preheat the Oven: Preheat your oven to 425°F (220°C). Line a large rimmed baking sheet (paid link) with parchment paper or lightly coat with oil.
  2. Prep and Season the Vegetables: Add the prepared sweet potatoes, zucchini, carrots, mushrooms, and broccoli florets into a large mixing bowl. Pour in the olive oil and season with the sea salt and black pepper. Shake and toss until the vegetables are evenly coated in oil and seasonings.
  3. Roast the Vegetables: Spread the seasoned veggies in an even, single layer across the prepared baking sheet (paid link). Bake for 30 minutes, flipping halfway through, until the sweet potatoes are fork-tender and the broccoli edges are lightly charred. Remove from the oven and set aside.
  4. Cook and Toss Quinoa: While the vegetables roast, prepare your quinoa. I use the Success Rice boil-in-bag quinoa. It is easy to make and perfectly fluffy every time. Transfer the hot, fluffy quinoa into a large serving bowl. Add the warm roasted veggies to the same bowl and gently toss. Set to the side.
  5. Make the Vinaigrette: In a separate medium bowl or mason jar (paid link), combine the olive oil, red wine vinegar, minced garlic, honey, Dijon mustard, red pepper flakes, sea salt, and black pepper. Whisk (paid link) vigorously (or seal the jar and shake) until the dressing is completely smooth, emulsified, and slightly thickened.
  6. Dress and Serve: Pour half of the prepared honey Dijon vinaigrette directly into the bowl with the warm quinoa and roasted vegetables. Gently fold the salad together until everything is evenly glossy and coated. Transfer the warm salad into a large serving dish and top off with the crumbled feta cheese (optional). Serve the remaining vinaigrette on the side for guests to drizzle as desired.

Notes

Uniform Knife Cuts: Cut your sweet potatoes into smaller ½-inch cubes, leaving the zucchini slightly larger. Since sweet potatoes take longer to soften than water-dense zucchini, this ensures all vegetables finish roasting at the exact same 30-minute mark.

Don’t Crowd the Pan: If your baking sheet (paid link) is too packed, the vegetables will steam in their own juices instead of caramelizing. Use two baking sheets if necessary to give every piece breathing room for maximum crisp edges.

Rinse the Quinoa First: Even if the package says pre-washed, a quick rinse in a fine-mesh colander under cold running water removes any remaining saponin (a natural plant coating that can taste slightly bitter or soapy).

Crunch & Herb Upgrades: Toss in ⅓ cup toasted pumpkin seeds (pepitas), chopped walnuts, or sliced almonds with fresh chopped parsley or basil right before serving for extra crunch.

Grain Swaps: If you don’t have quinoa on hand, this recipe works equally well with farro, wild rice, pearl couscous, or brown rice.

Veggie Swaps: Here is where you can get creative! You can substitute any vegetables of your choosing like turnips, Brussels sprouts, butternut squash, asparagus, or red potatoes.
