Description
Roasted Sweet Potato Salad with Lentils & Quinoa is a colourful, nourishing, and satisfying dish that combines caramelised sweet potatoes, tender lentils, fluffy quinoa, and fresh vegetables in one delicious bowl. Every bite brings together a wonderful balance of sweet, earthy, fresh, and tangy flavours.
The sweet potatoes become golden and slightly crispy around the edges when roasted, while the lentils add a hearty texture and the quinoa provides a light, fluffy base.

Ingredients
For the Roasted Sweet Potatoes
- 2 medium sweet potatoes, peeled if desired and cut into bite-sized cubes
- 2 tablespoons olive oil
- ½ teaspoon smoked paprika
- ½ teaspoon ground cumin
- ½ teaspoon garlic powder
- ¼ teaspoon black pepper
- ½ teaspoon salt, or to taste
For the Lentils and Quinoa
- 1 cup cooked brown or green lentils
- 1 cup cooked quinoa
- ¼ teaspoon salt, or to taste
- 1 tablespoon fresh lemon juice
You can use canned lentils for convenience. Drain and rinse them thoroughly before adding them to the salad. If cooking lentils and quinoa from scratch, prepare them according to their package directions and allow excess moisture to evaporate before assembling the salad.
For the Salad
- 2 cups fresh baby spinach or arugula
- 1 cup cherry tomatoes, halved
- 1 medium cucumber, diced
- ¼ small red onion, thinly sliced
- ¼ cup chopped fresh parsley
- ¼ cup crumbled feta cheese, optional
- ¼ cup toasted pumpkin seeds or chopped walnuts, optional
For the Lemon-Garlic Dressing
- 3 tablespoons extra-virgin olive oil
- 2 tablespoons fresh lemon juice
- 1 teaspoon Dijon mustard
- 1 small garlic clove, finely minced
- 1 teaspoon honey or maple syrup, optional
- ½ teaspoon dried oregano
- ¼ teaspoon black pepper
- Salt to taste
- 1–2 teaspoons water, if needed to thin the dressing
Equipment Needed
- Large baking sheet
- Parchment paper, optional
- Medium saucepan, if cooking lentils or quinoa
- Large mixing bowl
- Small bowl or jar for the dressing
- Sharp knife and cutting board
- Whisk or fork
Instructions
Step 1: Preheat the Oven
Preheat your oven to 425°F (220°C). A properly heated oven helps the sweet potatoes develop golden edges while remaining soft and tender inside.
Line a large baking sheet with parchment paper if desired. Make sure the baking sheet is large enough to spread the sweet potatoes in a single layer. Crowding the pan can cause them to steam instead of roast.
Step 2: Prepare the Sweet Potatoes
Wash the sweet potatoes thoroughly. Peel them if you prefer, or leave the skins on for extra texture after scrubbing them clean.
Cut the potatoes into evenly sized cubes, approximately ¾ inch each. Keeping the pieces similar in size helps them cook evenly.
Place the cubes in a large bowl. Add olive oil, smoked paprika, cumin, garlic powder, salt, and black pepper. Toss well until every piece is lightly coated with the seasoning mixture.
The combination of paprika and cumin creates a warm, savoury flavour that complements the natural sweetness of the potatoes.
Step 3: Roast Until Golden
Spread the seasoned sweet potatoes across the prepared baking sheet in a single layer. Leave a little space between the pieces whenever possible.
Roast for approximately 25–35 minutes, turning the potatoes halfway through cooking. They are ready when the edges are golden brown and a fork slides easily into the centre.
Cooking time may vary depending on the size of the cubes and your oven. For extra caramelisation, roast for a few additional minutes while watching carefully to prevent burning.
Remove the baking sheet from the oven and let the potatoes cool for about 5–10 minutes before assembling the salad.
Step 4: Prepare the Lentils
If using canned lentils, drain and rinse them under cool running water. Allow them to drain thoroughly.
If cooking dried lentils, simmer them in water according to the package instructions until tender but not mushy. Brown and green lentils generally hold their shape well in salads.
Drain any excess cooking liquid and let the lentils cool slightly. Season with a little salt and one tablespoon of lemon juice to give them a fresh, bright flavour.
Avoid overcooking the lentils because they should retain their shape when mixed with the other ingredients.
Step 5: Cook the Quinoa
Rinse the quinoa under cold water using a fine-mesh strainer to remove its natural bitter coating.
Combine one part quinoa with approximately two parts water in a saucepan, following the package instructions. Bring to a boil, reduce the heat, cover, and simmer until the quinoa absorbs the liquid and becomes tender.
Remove the saucepan from the heat and let the quinoa rest, covered, for about five minutes. Fluff it gently with a fork and allow it to cool slightly.
For this recipe, you need approximately one cup of cooked quinoa. If you already have cooked quinoa in your refrigerator, simply fluff it with a fork before using it.
Step 6: Make the Lemon-Garlic Dressing
In a small bowl, combine the olive oil, fresh lemon juice, Dijon mustard, minced garlic, dried oregano, black pepper, and a pinch of salt.
Add honey or maple syrup if you prefer a slightly sweeter dressing. Whisk everything together until the ingredients are well combined.
If the dressing tastes too sharp, add a little more olive oil or a small amount of sweetener. If it seems too thick, whisk in one or two teaspoons of water.
Taste and adjust the seasoning before pouring it over the salad. A good dressing should taste bright and balanced, with enough acidity to complement the sweet potatoes and earthy lentils.
Step 7: Prepare the Fresh Vegetables
Wash and dry the spinach or arugula thoroughly. If using large spinach leaves, tear them into smaller pieces.
Halve the cherry tomatoes, dice the cucumber, and thinly slice the red onion. Chop the fresh parsley.
For a milder onion flavour, soak the sliced red onion in cold water for five minutes, then drain and pat it dry.
Place the greens, tomatoes, cucumber, onion, and parsley in a large salad bowl.
Step 8: Assemble the Salad
Add the cooked lentils and quinoa to the bowl of fresh vegetables. Gently fold in the roasted sweet potatoes.
If the sweet potatoes are still very hot, allow them to cool slightly before adding them to the greens. This helps prevent the spinach or arugula from wilting too much.
Pour the lemon-garlic dressing over the salad. Toss gently until the ingredients are evenly coated.
Use a large spoon or salad tongs to mix everything without crushing the sweet potatoes or breaking apart the lentils.
Step 9: Add the Finishing Touches
Sprinkle the salad with crumbled feta cheese, if using. Add toasted pumpkin seeds or chopped walnuts for extra crunch.
Taste the finished salad and add more lemon juice, black pepper, or salt if needed.
For the best texture, serve the salad shortly after dressing it. If preparing it ahead, keep the dressing separate until just before serving.
Step 10: Serve and Enjoy
Transfer the salad to a large serving platter or individual bowls. Garnish with additional parsley, a few pumpkin seeds, or a light drizzle of olive oil.
Serve warm for a comforting meal, at room temperature for a potluck, or chilled for a refreshing lunch.
This salad is delicious on its own and also pairs beautifully with grilled chicken, baked salmon, roasted chickpeas, or warm whole-grain pita bread.
Notes
1. Choose the Right Sweet Potatoes
Look for firm sweet potatoes without soft spots or damaged areas. Orange-fleshed varieties provide a naturally sweet flavour and vibrant colour, while other varieties can also work well.
2. Use Lentils That Hold Their Shape
Brown or green lentils are ideal because they remain relatively firm after cooking. Red lentils tend to soften and break down, making them less suitable for this particular salad.
3. Prepare the Quinoa Properly
Rinse quinoa before cooking and let it rest after simmering. Fluffing it with a fork helps separate the grains and prevents the salad from becoming dense.
4. Adjust the Dressing
Lemons vary in acidity, so taste the dressing before using it. Add more lemon for brightness, olive oil for richness, or a little honey for sweetness.
5. Make It Vegetarian or Vegan
The recipe is vegetarian when made with the suggested ingredients. To make it vegan, omit the feta and use maple syrup instead of honey if sweetener is desired.
6. Keep the Ingredients Separate for Meal Prep
For the best texture, store the roasted sweet potatoes, quinoa, lentils, vegetables, and dressing separately whenever possible. Combine them shortly before eating.
7. Add More Vegetables
Roasted red peppers, shredded carrots, diced bell peppers, or thinly sliced radishes can add extra colour, flavour, and crunch.
8. Nutrition Will Vary
The nutritional values depend on the quantities of olive oil, feta, seeds, and dressing used. The figures below are estimates rather than laboratory-tested values.
Tips for the Best Roasted Sweet Potato Salad
- Do not overcrowd the baking sheet. Give the sweet potatoes enough space to brown instead of steam.
- Cut the potatoes evenly. Uniform cubes cook more consistently and make the salad easier to eat.
- Dry the greens well. Excess water can dilute the dressing and make the salad soggy.
- Cool the grains before mixing. Very hot quinoa can wilt the greens and warm the fresh vegetables too much.
- Toast the seeds. Briefly toasting pumpkin seeds or walnuts in a dry skillet enhances their flavor and crunch.
- Dress just before serving. This keeps the cucumber crisp and the greens fresh.
- Balance the flavors. The sweetness of the potatoes, earthiness of the lentils, freshness of the vegetables, and acidity of the dressing should complement one another.
- Add protein if desired. Chickpeas, grilled chicken, or baked tofu can make the salad more substantial.
- Use fresh lemon juice. It provides a brighter flavor than bottled lemon juice in most dressings.
- Taste before serving. A final pinch of salt, a little pepper, or an extra squeeze of lemon can bring all the flavors together.

Frequently Asked Questions (Q&A)
Q1: Can I make Roasted Sweet Potato Salad with Lentils & Quinoa ahead of time?
Yes. Roast the sweet potatoes and prepare the lentils and quinoa up to three days ahead. Store them in separate airtight containers in the refrigerator. Keep the fresh vegetables and dressing separate and assemble the salad shortly before serving for the best texture.
Q2: Can I use canned lentils?
Absolutely. Canned brown or green lentils are convenient and work very well. Drain and rinse them thoroughly, then allow them to dry before mixing them into the salad.
Q3: Can I use another grain instead of quinoa?
Yes. Cooked brown rice, farro, bulgur, or couscous can be substituted. The flavor, texture, cooking time, and nutritional profile will differ. If you need a gluten-free dish, choose a suitable gluten-free grain such as brown rice or millet.
Q4: Is this salad vegan?
It can be. Omit the feta cheese and use maple syrup instead of honey if you choose to sweeten the dressing. Check the labels of packaged ingredients to ensure they meet your dietary requirements.
Q5: Can I serve this salad cold?
Yes. It tastes delicious chilled or at room temperature. If serving it cold, allow the roasted sweet potatoes, lentils, and quinoa to cool before combining them with the fresh vegetables.
Q6: How can I add more protein?
Add chickpeas, baked tofu, grilled chicken, or another protein of your choice. Feta and pumpkin seeds also contribute some protein. The best option depends on your dietary preferences and nutritional goals.
Q7: What can I use instead of spinach?
Arugula, chopped kale, mixed salad greens, or finely shredded cabbage can work. If using kale, massage it briefly with a little dressing to soften its texture.
Q8: Can I make the salad without feta cheese?
Yes. The feta is optional. For a similar salty finish without dairy, try a few chopped olives or a small amount of capers. These alternatives will change the sodium content and flavor.
Q9: How should I store leftovers?
Transfer leftovers to an airtight container and refrigerate promptly. For best quality, enjoy the assembled salad within about 2–3 days. If possible, store the dressing separately to help keep the vegetables crisp. Discard any food left at room temperature for more than two hours, or one hour in temperatures above 90°F (32°C).
Q10: Can I freeze this salad?
Freezing the fully assembled salad is not recommended because the fresh vegetables and greens become watery after thawing. You can freeze cooked lentils and quinoa separately, but prepare the sweet potatoes and fresh vegetables fresh for the best texture.
Q11: Is this salad gluten-free?
The ingredients listed are naturally gluten-free when suitable products are used. Check labels on packaged lentils, seasonings, mustard, and other prepared ingredients if you need to avoid gluten strictly.
Q12: What should I serve with this salad?
Serve it with grilled chicken, baked fish, roasted chickpeas, hummus, or whole-grain pita bread. It also works well as a colorful side dish at a family gathering or potluck.
