This recipe starts with lentils as the main protein source. Lentils pack a punch with protein and fiber, making them filling and nutritious. Olive oil adds a healthy fat that enhances flavor.
Next, we have the vegetables. Onions and garlic form the base of the soup. They give it a rich aroma and taste. Carrots, celery, and zucchini add texture and nutrients.
The canned tomatoes bring a nice acidity. They make the soup bright and vibrant. Vegetable broth provides a flavorful liquid, making the soup cozy and warm.
Dried thyme and smoked paprika offer depth. They fill the soup with lovely aromas. Salt and pepper make everything taste better.
Finally, you can add kale or spinach for a pop of green and more nutrients. Fresh parsley adds a nice touch when you serve. This combination of ingredients makes a great high protein vegetable soup!

Step-by-Step Instructions
Initial Preparation
1. First, heat one tablespoon of olive oil in a large pot over medium heat.
2. Once the oil is hot, add one medium onion, finely diced. Sauté for about 3-4 minutes. Stir often until the onion is soft and clear.
3. Now, add two cloves of minced garlic to the pot. Cook for one more minute. The smell will be great!
4. Next, add two medium carrots, peeled and diced, along with two ribs of diced celery. Cook for about 5 minutes. Stir occasionally until they start to soften.
Cooking the Soup
5. Time to add the good stuff! Toss in one medium diced zucchini, one can of diced tomatoes (with juice), and one cup of rinsed lentils.
6. Now, pour in four cups of vegetable broth. Add one teaspoon of dried thyme and one teaspoon of smoked paprika. Season with salt and pepper.
7. Stir everything well to mix. Then, increase the heat until the soup boils. Once it boils, reduce the heat to low. Cover the pot and let it simmer for 25-30 minutes. The lentils and veggies should be tender.
Final Touches
8. In the last 5 minutes, stir in one cup of roughly chopped kale or spinach. Mix until the greens are wilted.
9. Taste your soup. Adjust the seasoning if needed with more salt or pepper.
10. For a thicker soup, use an immersion blender. Puree some of the soup and stir it back in for creaminess.
11. Serve hot. If you want, garnish with fresh parsley for a nice touch!
Tips & Tricks
How to Make the Soup More Flavorful
To boost flavor, use fresh herbs. Thyme works great. You can also add bay leaves while cooking. For a kick, sprinkle in some red pepper flakes. Try topping the soup with a dollop of yogurt or a sprinkle of cheese. Fresh parsley adds a nice touch too!
Achieving the Right Texture
For a creamy soup, use an immersion blender. Blend just part of the soup for a nice mix of textures. If the soup feels too thin, let it simmer longer. For a thicker soup, reduce the broth by half a cup.
Serving Suggestions
Pair the soup with crusty bread or a fresh salad. A slice of whole grain bread complements the soup well. You might also enjoy it with a side of roasted veggies for extra nutrition. A light cheese toast can be a tasty addition too!
Pro Tips
- Use Fresh Ingredients: Fresh vegetables will enhance the flavor and nutrition of your soup. Opt for seasonal produce whenever possible.
- Customize Your Greens: Feel free to substitute kale or spinach with other leafy greens like Swiss chard or collard greens for a different taste profile.
- Experiment with Spices: Add a pinch of cayenne pepper or a dash of lemon juice for an extra kick and a bright flavor contrast in your soup.
- Make it a Meal: Serve the soup over quinoa or with a side of whole-grain bread for a hearty and complete meal.
Variations
Dietary Alternatives
For a vegan version, this soup is already perfect! Just skip any animal products. Substitute vegetable broth if you need a richer flavor. For gluten-free options, check your broth. Many brands are gluten-free.
Ingredient Swaps
You can swap lentils for other legumes, like chickpeas or black beans. Quinoa is a great grain option too. When it comes to veggies, use what’s in season. Try butternut squash in fall or bell peppers in summer.
Different Flavor Profiles
If you like spice, add red pepper flakes or a chopped jalapeño. For an international twist, try adding curry powder or ginger for an Asian flair. You can even stir in some miso paste for a deeper taste.
Storage Info
Best Methods for Storing Leftovers
To keep your high protein vegetable soup fresh, store it properly. First, let it cool to room temperature. Then, transfer it to an airtight container. You can refrigerate the soup for up to four days. Make sure to label the container with the date.
For longer storage, freeze the soup. Use freezer-safe bags or containers. Leave some space for expansion. The soup can last up to three months in the freezer. When ready to eat, thaw it in the fridge overnight before reheating.
Reheating Instructions
To reheat your soup, pour it into a pot. Heat it over medium-low heat. Stir it often to avoid burning. You can also reheat it in the microwave. Use a microwave-safe bowl and cover it loosely. Heat in short intervals, stirring in between.
To keep the flavor and texture, do not boil the soup. Heating slowly helps maintain the taste and nutrients. If the soup seems thick after freezing, add a splash of vegetable broth or water while reheating. This will bring back its delicious consistency.
FAQs
Can I use dried lentils instead of canned?
Yes, you can use dried lentils. They add great texture and taste. Dried lentils need more time to cook. Rinse them first and then add them to the pot. For cooking, soak them for at least one hour. You should increase the vegetable broth by about 1 cup. Cook the soup for 30-35 minutes, until the lentils are soft.
How can I add more protein to the soup?
You can boost the protein in your soup in many ways. Here are some ideas:
- Chickpeas: Add one can of chickpeas, drained and rinsed.

- Nuts or seeds: Sprinkle in some roasted pumpkin seeds or chopped almonds.
These options will enhance both the protein and flavor of your soup.
