servings10
minutes40
minutesIngredients
1 tbsp olive oil
1 small onion, chopped
2 garlic cloves, minced
1 medium carrot, diced
1 medium sweet potato, peeled and diced (about 1½ cups)
½ cup dry whole brown or green lentils, rinsed
¼ cup dry quinoa, rinsed
1 cup canned diced tomatoes
4 cups low-sodium broth, plus more as needed
½ tsp ground cumin
¾ tsp smoked paprika
¼ tsp turmeric
½ tsp dried oregano
½ cup fresh chopped spinach
1–2 tsp lemon juice
Salt and black pepper to taste
Directions
- Heat olive oil in a large pot over medium heat. Add the chopped onion and carrot and sauté for 3–4 minutes, until they begin to soften.
- Add the minced garlic and cook for another 30 seconds, stirring frequently.
- Stir in the diced tomatoes, cumin, smoked paprika, turmeric, and oregano. Cook for 1–2 minutes to bring out the flavors.
- Add the diced sweet potato, rinsed lentils, quinoa, and vegetable broth. Give everything a good stir and bring it to a boil.
- Reduce the heat to low, partially cover the pot, and let everything simmer gently for 30–35 minutes, stirring occasionally.
- Cook until the lentils are completely tender and the sweet potatoes are soft. Depending on the type and age of your lentils, they may need a little longer. If the stew gets too thick while cooking, add a splash of broth or water.
- During the last 5 minutes of cooking, stir in the chopped spinach and let it cook until wilted.
- Use the back of a spoon to gently mash a few pieces of sweet potato against the side of the pot.
- Turn off the heat and stir in the lemon juice. Season with salt and pepper to taste. Serve warm and enjoy!
Notes
- How to Store and Reheat
Refrigerator: Allow the stew to cool, then transfer it to an airtight container and refrigerate within 2 hours. Store for up to 3–4 days.
Freezer: Freeze in individual portions in freezer-safe containers for up to 3 months for best quality.
Reheating: Reheat on the stovetop or in the microwave until steaming hot throughout.
The quinoa and lentils absorb liquid as the stew sits, so you may need to add a splash of water or broth when reheating.
Tips for Making the Best Sweet Potato Lentil Quinoa Stew
1. Cut the Sweet Potatoes into Small Pieces
Try to keep the sweet potato cubes fairly small and evenly sized. This helps them cook at the same time as the lentils.
Some pieces will naturally break down while cooking, which makes the stew even creamier.
2. Use Whole Lentils
I recommend brown or green lentils for this recipe because they hold their shape better.
Red split lentils cook much faster and break down more easily, so they would change the texture and cooking time of this recipe.
3. Adjust the Consistency
I personally love this stew thick and hearty, but you can easily make it more soup-like by adding extra vegetable broth.
Keep in mind that quinoa continues absorbing liquid as the stew sits, so leftovers may be thicker the next day.
4. Don’t Skip the Lemon Juice
A little lemon juice at the end makes such a difference! It balances the sweetness of the sweet potatoes and brightens up the flavors.
It also provides vitamin C, which can help your body absorb the non-heme iron found in lentils and quinoa.
5. Make Sure the Lentils Are Fully Cooked
Cooking times can vary depending on the type of lentils you’re using. If they still feel firm after 35 minutes, continue simmering and add more liquid if necessary.
Ingredient Substitutions and Variations
Can I use tomato paste instead of diced tomatoes?
Yes! Replace the 1 cup of diced tomatoes with 2 tablespoons of tomato paste.
Cook the tomato paste with the garlic and spices for 1–2 minutes, then increase the broth to approximately 4 cups. Start with slightly less liquid if you prefer a thicker stew and add more as needed.
Can I use frozen spinach?
Absolutely! Use about ½ cup of frozen chopped spinach instead of fresh spinach.
There’s no need to thaw it first. Just add it during the last 5 minutes of cooking and stir until completely heated through.
Can I use red lentils?
You can, but the stew will have a different texture. Red lentils break down quickly and will make the stew much softer and creamier.
If using red lentils, adjust the cooking time and add the quinoa and sweet potatoes according to their tenderness, rather than following the original timing exactly.
Can I add other vegetables?
Definitely! Zucchini, peas, kale, or butternut squash would all work well.
Can I make it spicier?
For adults, you can add red pepper flakes, cayenne pepper, or a little chili powder. I usually keep the base recipe mild and add heat to individual servings.
Is This Stew Good for Toddlers?
Yes! This is one of my favorite ways to serve lentils and quinoa to my toddler because everything is cooked together until soft and flavorful.
The sweet potatoes add a little natural sweetness, which balances the earthy flavor of the lentils.
Here are a few ways to make it toddler-friendly:
- Dice the vegetables into small, manageable pieces.
- Cook the lentils until completely tender.
- Mash the stew slightly for younger toddlers who prefer softer textures.
- Use low-sodium vegetable broth and adjust added salt according to your child’s age.
- Let the stew cool to a safe temperature before serving.
For babies who are ready for solids, you can offer an appropriately mashed or blended version, provided the ingredients and texture are suitable for their developmental stage. Avoid added salt for babies under 12 months.
