- Beans: Boost the plant-based protein with a can of beans – white beans, chickpeas, kidney beans, pinto beans, etc.

How to Make Vegetable Soup with Quinoa
Step 1: First, heat the oil in a large, heavy-based pot over medium heat. Once hot, sauté the cherry tomatoes until they begin to burst.
Step 2: Then, dice the onion and bell pepper, slice the celery and carrots, and mince the garlic. Also, rinse the quinoa well and leave it to drain. Stir in the garlic and sauté for 1 minute. Then, add the remaining veggies, Italian seasoning, salt, and pepper. Sauté for 5 minutes.
Step 3: Add the quinoa and broth (or water + bouillon cubes), stir, and bring to a boil. Lower the heat to a simmer and cook undisturbed for 20 minutes.
Step 4: Remove the veggie quinoa soup from the heat, uncover, and stir in the spinach/kale and the juice from half a lemon. Cover and rest for 10 minutes. Finally, taste and adjust the seasonings/lemon, optionally garnish with parsley or sliced green onions, and serve. Enjoy!
FAQs
Yes! Some prefer cooking and storing grains separately, as they absorb broth and soften over time. Cook the quinoa in vegetable broth using your preferred method. A complete guide to quinoa here.
This vegetable and quinoa soup recipe is very forgiving. Great substitutes include farro, barley, bulgur, amaranth, freekeh, wild rice, or even giant couscous or orzo.
Cook them separately, adjust the simmer time, or use leftover cooked grains.
For the best flavor, sauté the veg in a skillet first. Then, transfer everything to a slow cooker and cook on LOW for 6-8 hours or HIGH for 3-5 hours.
Pro Recipe Tips
- Brown the veggies: This caramelization adds depth to the overall soup flavor. Just be careful they don’t burn – adjust heat if necessary.
- Rinse the quinoa: To remove its natural bitter coating (caused by saponins).
- Use rich stock/broth: Use homemade or store-bought (liquid or cubes) veg stock you like the flavor of since it’s the main soup base.
- For thicker/ creamier soup: Blend a portion of broth + veggies and stir it into the soup.
- Soup vs. Stew: Adjust the amount of quinoa and veggies for a brothy soup or a thick stew.
Serving Suggestions
Quinoa in vegetable soup makes it hearty enough to enjoy as a full meal – complete with fiber, vitamins, minerals, antioxidants, and plant-based protein. However, you might enjoy it with:
- Bread for dipping – A slice of the easiest no-knead bread, a easy vegan dinner roll, sweet potato cornbread.
- A sandwich – like a vegan grilled cheese or vegan bagel sandwich with pesto.
- A leafy side salad – or a vegan Caprese salad/ Greek cucumber salad
Storage Information
Fridge: Leave the quinoa vegetable soup to cool, then store leftovers in airtight containers for 4-5 days. Note quinoa will soak up broth as it sits.
Freeze: In Ziplock’s, souper cubes, or a silicone muffin tray for 3-4 months. It’s best done minus the quinoa (which may become mushy upon thawing), which can be added when reheating.
Reheat: In a microwave (30-second increments, stirring between) or on the stove (medium-low heat until piping hot). Add extra broth if needed.
