List of ingredients

2 tablespoons olive oil
1 onion, diced
3 carrots, peeled and diced
2 ribs celery, diced
2 cloves garlic, minced
1 teaspoon dried thyme
1 teaspoon dried oregano
1/4 teaspoon red pepper flakes (optional)
1 teaspoon salt
1 cup quinoa, raw
1 can (14 oz.) white beans, strained and rinsed
1 can (28 oz.) diced tomatoes
4 cups vegetable broth
2 cups water
1 bay leaf
1 microbial-rennet parmesan rind
2 cups spinach, roughly chopped

step-by-step instructions

Step: In a large pot on medium-high heat, warm the olive oil.
Step: Add the onion, carrot, and celery and sauté for 3-4 minutes until tender. Then add the minced garlic and cook for an additional 1-2 minutes until tender.
Step: Add the dried thyme, dried oregano, red pepper flakes, and salt, and sauté for an additional minute until fragrant.
Step: Pour in the quinoa, white beans, and diced tomatoes and stir to combine with the vegetables.
Step: Pour in the broth and water and stir again until everything is well incorporated.
Step: Add the parmesan rind and bay leaf to the pot and stir to ensure they are submerged in the broth.
Step: Bring the soup to a boil, then reduce to a simmer, and cook for 20 minutes, stirring occasionally, until the quinoa is tender.
Step: Once cooked, add the chopped spinach, stir until well incorporated in the soup, and simmer for a final 5 minutes until the spinach is wilted. If you find the soup too thick, simply add some more water or broth to thin the soup to your liking.
Step: Remove the parmesan rind and bay leaf, then taste the soup, and adjust the seasoning with additional salt and black pepper as needed.
Step: Serve the soup immediately or allow it to cool completely and store it in the fridge for up to 5 days or in the freezer for up to 3 months.

Cooking and Preparation Suggestions

Selecting the Best Quinoa Variety

You can use white, red, or tri-color quinoa for this recipe without changing the cooking time significantly. White quinoa is the mildest and softest, while red and tri-color varieties retain a slightly nuttier flavor and a firmer, crunchier texture even after simmering in the broth.

Enhancing Umami without Meat

The parmesan rind is a secret weapon for depth, but if you want to keep the dish strictly plant-based, consider a tablespoon of tomato paste or a splash of soy sauce. These ingredients offer a similar savory quality that balances the acidity of the tomatoes and the earthiness of the beans.

Managing Soup Consistency

Quinoa acts like a sponge and will continue to absorb liquid even after the heat is turned off. If the soup appears too thick upon reheating, simply whisk in an extra half-cup of vegetable broth or water to restore your preferred consistency.

Customizing Your Soup Bowl

Incorporating Seasonal Vegetables

Feel free to toss in summer squash, zucchini, or chopped kale during the final simmering stages. If you prefer sturdier additions like diced sweet potatoes or butternut squash, add them along with the carrots and celery so they have enough time to cook through completely.

Adding Extra Protein Sources

While the combination of quinoa and white beans provides a high-quality protein profile, you can increase the heartiness by adding cooked chickpeas or even lentils. These legumes blend seamlessly with the Italian flavors and provide a different texture for those who prefer more variety in every bite.

Brightening Flavors with Acid

A fresh squeeze of lemon juice stirred in just before serving acts as a flavor brightener that cuts through the starchiness of the grains. This simple addition makes the herbs pop and gives the soup a lighter, more vibrant profile, especially when served on warmer days.

Proper Storage and Reheating

Freezing for Long Term Use

This soup is an excellent candidate for the freezer because the ingredients hold their shape well after thawing. Freeze in individual portions to make grab-and-go lunches, leaving about an inch of space at the top of your containers to allow for expansion during the freezing process.

Safe Thawing Methods

The best way to thaw your frozen soup is to transfer it from the freezer to the refrigerator the night before you plan to eat it. If you are in a rush, you can place the container in a bowl of cool water, changing the water every twenty minutes, though gentle refrigerator thawing maintains the best ingredient integrity.

Addressing Common Cooking Questions

Can I use cooked quinoa instead of raw?

You can use previously cooked quinoa, but you must reduce the simmering time significantly. Add the cooked grain during the final 5 minutes of cooking to ensure it just heats through without turning mushy or overcooked in the broth.

Is this recipe suitable for slow cooker preparation?

Yes, you can combine all ingredients in a slow cooker and set it to low for 4-5 hours or high for 2-3 hours. This method is ideal for hands-off cooking, though you should still add the fresh spinach at the very end to keep its vibrant color and texture.

How can I avoid bitter grains?

Quinoa is coated in a natural substance called saponin, which can taste bitter if not washed off. Place the dry quinoa in a fine-mesh strainer and rinse it thoroughly under cold running water for at least 30 seconds, rubbing the grains together with your fingers before adding them to the pot.

What is the shelf life in the refrigerator?

Stored in an airtight container, the soup will remain fresh for up to 5 days. Ensure the soup has cooled to room temperature before placing it in the fridge to prevent excessive moisture buildup inside the container, which can impact the texture of the vegetables.

Can I substitute dried herbs with fresh ones?

You certainly can, but keep in mind that dried herbs are more concentrated in flavor. As a general rule, use three times the amount of fresh herbs compared to the dried measurement; add them during the final minutes of cooking to preserve their volatile oils and bright color.
