Step‑by‑Step Instructions for High-Protein Vegetable Soup

Step 1: Sauté the Aromatics
In a large pot, heat 2 tablespoons of olive oil over medium heat. Once shimmering, add 1 diced onion and 2 minced garlic cloves, sautéing for about 3-5 minutes until the onion becomes translucent and fragrant. This base will infuse your High-Protein Vegetable Soup with deep, savory flavors that awaken the senses.

Step 2: Add the Vegetables
Next, introduce 2 diced carrots, 2 chopped celery stalks, and 1 diced red bell pepper to the pot. Stir the vegetables and sauté for an additional 5-7 minutes until they soften and take on a light golden hue. This colorful medley enhances the visual appeal while providing essential nutrients to your wholesome soup.

Step 3: Incorporate the Broth and Lentils
Pour in 6 cups of vegetable broth and add 1 cup of rinsed lentils to the pot. Bring the mixture to a boil over high heat, then reduce the heat to medium-low and let it simmer uncovered for 15 minutes. You’ll notice the lentils gaining a tender texture, thickening the soup as it develops a rich, hearty base.

Step 4: Stir in the Protein Boost
Add 1 can each of chickpeas and black beans (drained and rinsed), along with 1 teaspoon each of dried thyme and basil, along with salt and pepper to taste. Continue to simmer for another 10 minutes, allowing the flavors to meld beautifully. This step enhances the protein content of your High-Protein Vegetable Soup, making it a satisfying meal.

Step 5: Add the Greens and Final Veggies
Stir in 2 cups of chopped kale, 1 cup of trimmed green beans, and 1 cup of frozen peas. Cook for an additional 5-7 minutes until the greens are wilted and the green beans are tender yet still vibrant. This is the finishing touch that introduces both nutrition and texture, making each spoonful enjoyable.

Step 6: Brighten with Citrus and Garnish
Remove the pot from heat and mix in the juice of 1 lemon and ¼ cup of chopped fresh parsley. This final flourish not only brightens up the flavors of your High-Protein Vegetable Soup but also adds a fragrant freshness that elevates the entire dish.

Step 7: Adjust and Serve
Before serving, taste the soup and adjust the seasoning as needed with additional salt or pepper. Serve piping hot, garnished with extra parsley if desired, alongside crusty bread or over grains for a complete meal. This comforting soup is a delightful way to nourish yourself on any cozy night.
