How to Make Dijon Mustard Quinoa Salad with Roasted Vegetables
Prep the Oven & Roast Vegetables
Preheat the oven to 400°F. Add the carrots and sweet potatoes to a baking sheet and toss with 2 teaspoons olive oil and a generous pinch of salt. Roast for 15 minutes.
Second Round of Roasting
While the first veggies roast, add the radishes and onions to a second baking sheet. Toss with the remaining 2 teaspoons olive oil and a generous pinch of salt. After the sweet potatoes and carrots have roasted for 15 minutes, toss them together on the baking sheet and return it to the oven. Place the second baking sheet in the oven as well. Roast everything for another 15 minutes until the vegetables soften and develop light caramelization.
Cook Fluffy Quinoa
While the veggies roast, bring 2 cups of water to a boil in a small saucepan. Add the quinoa, return to a boil, then reduce to a simmer. Cover and cook for 12 minutes, or until all the water is absorbed. Remove from heat, fluff with a fork, cover, and let the quinoa sit for 15 minutes to perfect its texture.
Whisk the Dressing
In a small bowl or jar, whisk together the honey, olive oil, Dijon mustard, red wine vinegar, garlic, and jalapeños until the mixture emulsifies to form a creamy, flavorful dressing.
Assemble the Salad
In a large mixing bowl, combine the prepared quinoa, roasted vegetables, feta, and pumpkin seeds. Drizzle with the honey mustard dressing and give it a gentle stir. Top with fresh herbs for a final burst of color and flavor, then serve.
Perfectly Roasted Vegetables: Tips & Techniques
Achieving Even Roasting
- Cut the vegetables into uniform sizes for consistent cooking.
- Use parchment paper to prevent sticking and easier cleanup.
- Place the baking sheets on the center oven rack for balanced heat distribution.
- Flip vegetables halfway through roasting to ensure even caramelization.
Sneaky Storage Tips
- Store roasted veggies in an airtight container for up to 4 days.
- Keep the dressing separate to maintain the salad’s texture.
- Refrigerate quinoa and vegetables separately, combining everything just before serving.
Pro Tips & Troubleshooting
Pro Tips
- Spread vegetables in a single layer to avoid steaming.
- Stick to the 2:1 water-to-quinoa ratio to prevent soggy results.
- Keep dressing and fresh herbs separate until ready to serve for optimal freshness.
Common Mistakes to Avoid
- Skipping the resting step for quinoa can lead to mushy grains.
- Over-mixing the salad after adding feta can lead to a less visually appealing dish.
- Using too much oil can result in greasy roasted vegetables instead of crisp, caramelized textures.
Serving & Storage
Serving Ideas
- Serve warm for a cozy, satisfying meal.
- Add grilled chicken or baked tofu for extra protein.
- Pair with crusty bread or pita to make it a filling, hearty dish.
Storage and Make-Ahead Tips
- Store leftovers in the fridge for up to 4 days, separating the dressing and salad ingredients.
- Freeze roasted veggies for up to 3 months; thaw and reheat when needed.
- For meal prep, prepare all components ahead of time and combine just before serving for best texture.
