Ingredients Method

Ingredients

  

• 2 tablespoons extra-virgin olive oil
• 1 medium yellow onion, diced
• 3 cloves garlic, minced
• 2 medium carrots, sliced
• 2 celery ribs, sliced
• 1 red bell pepper, diced (optional but recommended)
• 1 teaspoon ground cumin
• 1 teaspoon dried oregano
• 1/2 teaspoon smoked paprika (or sweet paprika)
• 1 cup uncooked quinoa, rinsed well
• 1 can (14–15 oz) diced tomatoes, with juices
• 6 cups low-sodium vegetable broth (plus more as needed)
• 1 can (14–15 oz) chickpeas or white beans, drained and rinsed
• 2 cups chopped hearty greens (kale, spinach, or Swiss chard)
• 1 small zucchini, diced (optional)
• 1 bay leaf
• Salt and freshly ground black pepper, to taste
• Juice of 1/2 to 1 lemon, to taste
• 2 tablespoons chopped fresh parsley or cilantro, plus more for serving
• Crushed red pepper flakes, to taste (optional)

Method

 

1. Warm the pot. Heat the olive oil in a large soup pot over medium heat. Add onion, carrots, and celery. Cook 5–7 minutes, stirring occasionally, until the vegetables soften and the onion turns translucent.
2. Build flavor. Stir in the bell pepper, garlic, cumin, oregano, and smoked paprika. Cook 1 minute until fragrant. Don’t let the garlic brown.
3. Add the base. Pour in the diced tomatoes with their juices, the rinsed quinoa, vegetable broth, and bay leaf. Stir to combine and bring to a gentle boil.
4. Simmer. Reduce heat to medium-low and simmer uncovered for 15 minutes, stirring once or twice to keep the quinoa from settling at the bottom.
5. Stir in protein and greens. Add the chickpeas (or white beans), zucchini if using, and greens. Simmer another 5–8 minutes, until quinoa is tender and the greens are wilted. Add a splash of broth if the soup thickens more than you’d like.
6. Season and brighten. Remove the bay leaf. Stir in the lemon juice and fresh herbs. Taste and season with salt, black pepper, and red pepper flakes if you like a little heat.
7. Serve. Ladle into bowls and finish with a drizzle of olive oil or extra herbs. For extra richness, add a spoonful of plain yogurt or a sprinkle of grated Parmesan (if not keeping it vegan).

Why This Recipe Works

• Quinoa cooks in the pot with the vegetables, soaking up flavor and releasing natural starches that give the broth a light, velvety body.
• Layered aromatics (onion, garlic, carrots, celery) build a savory base so the soup tastes slow-simmered in a fraction of the time.
• Two protein sources—quinoa and beans—make the soup filling and balanced without needing meat.
• Simple seasoning with tomato, herbs, and lemon keeps it bright, not muddy, so each ingredient shines.
• Flexible veggies mean you can use what you have: zucchini, kale, bell peppers, or frozen peas all fit right in.

How to Make It

1. Warm the pot. Heat the olive oil in a large soup pot over medium heat. Add onion, carrots, and celery.

   Cook 5–7 minutes, stirring occasionally, until the vegetables soften and the onion turns translucent.

2. Build flavor. Stir in the bell pepper, garlic, cumin, oregano, and smoked paprika. Cook 1 minute until fragrant. Don’t let the garlic brown.
3. Add the base. Pour in the diced tomatoes with their juices, the rinsed quinoa, vegetable broth, and bay leaf.

   Stir to combine and bring to a gentle boil.

4. Simmer. Reduce heat to medium-low and simmer uncovered for 15 minutes, stirring once or twice to keep the quinoa from settling at the bottom.
5. Stir in protein and greens. Add the chickpeas (or white beans), zucchini if using, and greens. Simmer another 5–8 minutes, until quinoa is tender and the greens are wilted. Add a splash of broth if the soup thickens more than you’d like.
6. Season and brighten. Remove the bay leaf.

   Stir in the lemon juice and fresh herbs. Taste and season with salt, black pepper, and red pepper flakes if you like a little heat.

7. Serve. Ladle into bowls and finish with a drizzle of olive oil or extra herbs. For extra richness, add a spoonful of plain yogurt or a sprinkle of grated Parmesan (if not keeping it vegan).

Keeping It Fresh

• Storage: Cool completely, then refrigerate in airtight containers for up to 4 days.

  The flavors deepen by day two.

• Freezer-friendly: Freeze in portions for up to 3 months. Leave a little headspace for expansion. Thaw overnight in the fridge.
• Reheating: Warm on the stovetop over medium heat.

  Add water or broth as needed—quinoa continues to absorb liquid and can thicken the soup over time.

• Meal prep tip: Keep extra lemon wedges on hand for brightening leftovers right before serving.

Benefits of This Recipe

• High in plant-based protein: Quinoa is a complete protein, and beans add even more staying power.
• Fiber-rich: Vegetables, beans, and quinoa deliver fiber that supports digestion and satiety.
• Nutrient-dense: You’ll get vitamins A, C, K, and a spectrum of minerals like iron and magnesium.
• Low in saturated fat: It’s naturally heart-friendly and easy on the stomach.
• Adaptable for many diets: Naturally vegan and gluten-free, with simple swaps for different preferences.

Pitfalls to Watch Out For

• Not rinsing the quinoa: Skipping this can leave a bitter, soapy taste due to saponins. Rinse in a fine-mesh strainer for 30 seconds.
• Overcooking the greens: Add them near the end so they stay vibrant and tender, not gray and limp.
• Under-seasoning: Salt in stages and finish with lemon. Acid wakes up the flavors, especially in tomato-based soups.
• Too thick or too thin: Adjust with broth.

  The soup will thicken as it sits; keep extra stock on hand.

• Burning aromatics: If garlic or spices scorch, the whole pot can taste bitter. Keep the heat moderate and stir.

Alternatives

• Protein swaps: Use lentils instead of quinoa (simmer 20–25 minutes) or add diced cooked chicken or turkey for a hybrid version.
• Bean options: Black beans, cannellini, or lentils all work. Mix two types for texture.
• Grain changes: Brown rice or farro can replace quinoa.

  Adjust cook time and add more broth as needed.

• Veggie variations: Try sweet potato, butternut squash, green beans, or frozen peas. Add hardy vegetables earlier, delicate ones at the end.
• Flavor twists: Stir in a spoonful of pesto before serving, add a dash of soy sauce for umami, or use curry powder and coconut milk for a creamy spin.

FAQ

Do I have to rinse quinoa?

Rinsing removes saponins that taste bitter. It takes less than a minute and makes a big difference in flavor, so it’s worth it.

Can I make this in a slow cooker?

Yes.

Sauté aromatics first for best flavor, then cook on Low for 4–5 hours with the quinoa, tomatoes, and broth. Add beans and greens in the last 30 minutes to avoid mushy textures.

What if I only have chicken broth?

Go for it if you’re not vegetarian. The soup will still be delicious, just no longer vegan.

Adjust salt since many chicken broths are saltier than vegetable broth.

How can I add more protein?

Use both chickpeas and white beans, stir in a scoop of hemp seeds before serving, or add diced cooked chicken or turkey. For a plant-based boost, add edamame in the last few minutes.

Will the quinoa get mushy?

It will stay pleasantly tender if you simmer just until done and avoid overcooking. On reheating, add broth to loosen the texture and keep it from feeling dense.

Can I make it spicy?

Yes.

Add red pepper flakes with the spices or stir in harissa or a chopped jalapeño. Adjust to your heat preference.

What’s the best way to thicken the soup?

Simmer uncovered a bit longer, or mash a small portion of the beans and stir them back in. The starch adds body without cream.
