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. Add 1 chopped onion and 3 minced garlic cloves, sautéing for 3-4 minutes until the onion becomes translucent. This foundation will build the flavor for your high-protein vegetable soup, and the garlic should become fragrant but not browned.
Step 2: Add the Vegetables
Stir in 2 chopped carrots, 2 chopped celery stalks, and 1 diced red bell pepper. Continue sautéing for about 5 minutes, allowing the vegetables to soften slightly. You'll notice the vibrant colors starting to blend, creating a colorful base for your soup.
Step 3: Build the Broth
Pour in 6 cups of vegetable broth and add 1 cup of lentils. Increase the heat to bring the mixture to a boil, then reduce to a simmer. Cover the pot and let it cook for 15 minutes, stirring occasionally. The lentils should be tender but not mushy, thickening the broth beautifully.
Step 4: Mix in the Beans and Herbs
Add 1 can of drained chickpeas, 1 can of drained black beans, 1 teaspoon of dried thyme, 1 teaspoon of dried basil, and salt and pepper to taste. Allow this mixture to simmer uncovered for another 10 minutes. This will enrich the soup with protein and herbs, enhancing the delicious aroma wafting through your kitchen.
Step 5: Incorporate the Greens
Next, stir in 2 cups of chopped kale, 1 cup of cut green beans, and 1 cup of frozen peas. Cook the soup for an additional 5-7 minutes until the greens are tender and bright, adding both vibrant color and nutrition to your high-protein vegetable soup.
Step 6: Finish with Freshness
Remove the pot from heat and stir in the juice of 1 lemon and ¼ cup of chopped fresh parsley. This finishing touch brightens the flavors and gives your soup a fresh, zesty kick.
Step 7: Adjust and Serve
Taste and adjust the seasonings with more salt and pepper if needed. Serve the steaming high-protein vegetable soup hot, garnished with additional parsley for a delightful presentation. Enjoy this comforting dish, perfect with a side of crusty bread!
How to Store and Freeze High-Protein Vegetable Soup
Fridge: Store in an airtight container for up to 5 days. Let the soup cool before refrigerating to maintain its freshness.
Freezer: Freeze in freezer-safe containers or bags for up to 3 months. For the best flavor, omit fresh parsley and lemon juice before freezing.
Reheating: Thaw overnight in the fridge if frozen, then gently reheat on the stove or in the microwave until heated through. Add a splash of lemon juice before serving for an extra zing!

High-Protein Vegetable Soup Variations

Expert Tips for High-Protein Vegetable Soup

- Protein Boost: Want more protein? Adding tofu or tempeh is a fantastic option; adjust cooking time so they heat through, blending perfectly into the soup.
- Vegetable Variations: Feel free to swap in seasonal veggies! Zucchini or spinach can be great substitutes for kale, keeping the soup fresh and vibrant.
- Storage Tip: To maintain flavor, store the soup in the fridge for up to 5 days. If freezing, leave out the fresh parsley and lemon juice until reheating.
Make Ahead Options
These High-Protein Vegetable Soup components are perfect for meal prep! You can chop the vegetables—onion, carrots, celery, and bell pepper—up to 24 hours in advance and store them in the refrigerator to save time for busy weeknights.

To maintain the quality, be sure to keep the soup in an airtight container and avoid adding kale and peas until you’re ready to heat and finish. When you're set to serve, simply combine everything in a pot, reheat gently, add lemon juice and parsley, and enjoy a hearty, nourishing meal that feels fresh and delicious!
High-Protein Vegetable Soup Recipe FAQs
What should I look for when selecting fresh vegetables?
Absolutely! When choosing fresh vegetables for your High-Protein Vegetable Soup, look for vibrant colors and firm textures. For example, carrots should be bright orange with minimal blemishes, and bell peppers should be smooth and free of wrinkles. Avoid any vegetables with dark spots or soft patches, as they indicate spoilage or overripeness.
How long can I store the soup in the refrigerator?
You can store your High-Protein Vegetable Soup in the refrigerator for up to 5 days. Make sure to transfer it to an airtight container once it has cooled down to keep it fresh. Just give it a quick stir and a taste to adjust the seasoning before enjoying!
Can I freeze this soup, and if so, how?
Yes, you can freeze your High-Protein Vegetable Soup for up to 3 months! Allow the soup to cool completely before packaging it. I recommend portioning it into freezer-safe bags or containers, leaving some space for expansion. For the best flavor, omit the fresh parsley and lemon juice before freezing. When ready to enjoy, thaw it overnight in the refrigerator, and then gently reheat on the stove, adding a splash of lemon juice for brightness.
What if my soup turns out too thick or too thin?
Very common! If your High-Protein Vegetable Soup ends up too thick, simply add a bit more vegetable broth or water while stirring over low heat until you reach your desired consistency. On the other hand, if it’s too thin, let it simmer uncovered for a few extra minutes to allow some of the liquid to evaporate. The beauty of making soup is that you can always adjust it to your liking!
Is this soup suitable for people with allergies?
Absolutely! The High-Protein Vegetable Soup is naturally vegan and gluten-free, making it suitable for many dietary restrictions. However, be cautious with canned beans and any pre-packaged vegetable broth, as they may contain allergens. Always check labels if you're serving this to someone with food allergies.
What are some great variations for this soup?
Feel free to get creative! Swap out the chickpeas or black beans for other beans, like cannellini or navy beans, for a different flavor profile. You can also add seasonal vegetables like zucchini or spinach in place of kale. For a little kick, sprinkle in some cumin or smoked paprika during cooking! The more the merrier when it comes to personalizing your soup!
