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

Step 1: Sauté Aromatics
In a large pot, heat 2 tablespoons of olive oil over medium heat. Once shimmering, add one diced onion and two minced garlic cloves. Sauté for about 5 minutes until the onion is translucent and fragrant, stirring frequently to prevent sticking. This forms the flavor base of your High-Protein Vegetable Soup.

Step 2: Add Vegetables
Toss in 2 diced carrots, 2 stalks of diced celery, and 1 chopped red bell pepper. Sauté these vibrant veggies for 5–7 minutes, allowing them to soften and slightly brown. The colors will brighten, adding both flavor and nutrition to your soup, and the kitchen will fill with delightful aromas.

Step 3: Incorporate Broth and Lentils
Pour in 6 cups of vegetable broth and add 1 cup of rinsed lentils. Stir well and bring the mixture to a rolling boil over high heat. Once boiling, reduce the heat to a low simmer, covering the pot, and let it cook for 15 minutes. The lentils will start to soften, thickening the soup’s consistency.

Step 4: Mix in Proteins and Herbs
Add 1 can each of drained chickpeas and black beans, along with 1 teaspoon each of dried thyme and basil. Season with salt and pepper to taste. Allow the High-Protein Vegetable Soup to simmer uncovered for another 10 minutes, stirring occasionally, so the flavors meld beautifully.

Step 5: Stir in Greens
Now it’s time to add 2 cups of chopped kale, 1 cup of trimmed and chopped green beans, and 1 cup of frozen peas to the pot. Cook for an additional 5–7 minutes until the greens are vibrant and tender. They will give the soup a lovely texture while maintaining essential nutrients.

Step 6: Finishing Touches
Remove the pot from the heat and mix in the juice of 1 lemon and a handful of chopped fresh parsley. Stir well to incorporate the bright citrus flavor, which will elevate the entire dish, enhancing the taste of your nourishing High-Protein Vegetable Soup.

Step 7: Taste and Serve
Before serving, give the soup a final taste to adjust any seasoning needed. Serve hot, garnished with extra parsley for color and fresh aroma. Enjoy your soul-warming High-Protein Vegetable Soup with a slice of crusty bread or over a bed of grains for a complete meal.

High-Protein Vegetable Soup Recipe FAQs

How do I select the right vegetables for this soup?
Absolutely! For the best flavor, choose vegetables that are fresh, vibrant, and free of blemishes. Look for carrots that are firm and brightly colored, and celery that is crisp and crunchy. If the kale has dark spots, it’s best to skip it for this recipe. Seasonal vegetables typically yield the greatest flavor, so don’t hesitate to customize based on what’s available!

What’s the best way to store leftover High-Protein Vegetable Soup?
Very simple! Store your leftovers in an airtight container in the fridge for up to 5 days. Just make sure the soup cools down to room temperature before sealing. To keep it fresh and delicious, reheat it on the stove over medium heat, stirring occasionally.

Can I freeze High-Protein Vegetable Soup?
Absolutely! This delightful soup can be frozen for up to 3 months. Transfer it into freezer-safe containers, leaving some space at the top for expansion. For the best results, I recommend not adding fresh herbs and lemon juice before freezing; add them right before serving to keep that freshness intact.

What if my soup is too thick?
No worries! If your soup has thickened more than you’d like after cooking or reheating, simply add a little bit of vegetable broth or water, stirring it in gradually until you reach your desired consistency. Remember, the thickness can vary based on how much water evaporates during cooking and the type of lentils used.

Are there any dietary considerations I should keep in mind?
Definitely! This High-Protein Vegetable Soup is vegan and gluten-free; however, if you’re cooking for family or friends, check for allergies. Chickpeas and black beans are common allergens, so feel free to substitute with other legumes like lentils. If you have pets, ensure that ingredients like onions and garlic are kept away, as they can be toxic to dogs and cats.

How should I adjust the seasoning if I’m using low-sodium broth?
Great question! Start with a pinch of salt and gradually season to taste as the soup simmers. Since low-sodium broth has less flavor, it’s crucial to keep tasting as you go. Incorporate spices like thyme and basil early on to build flavors, and add more salt and pepper towards the end for the best results. Adjusting as you go will ensure a perfectly seasoned High-Protein Vegetable Soup.
