Why I Love This Vegetarian Protein Soup

• Ideal for meal prep. The leftovers taste even better after the flavors meld together in the fridge, and the soup freezes extremely well for fast future meals.
• Hearty and filling. Whole grains, legumes, and vegetables all come together to help keep you full and energized for hours.

Ingredients

This is everything I use to make a big pot of vegetarian protein soup:

• 2 tablespoons olive oil
• 1 medium onion, diced
• 3 cloves garlic, minced
• 2 carrots, chopped
• 2 celery stalks, sliced
• 1 red bell pepper, chopped
• 1 zucchini, diced
• 1 cup chopped mushrooms
• 1 can (15 oz) diced tomatoes
• 1 can (15 oz) chickpeas, rinsed and drained
• 1 can (15 oz) black beans, rinsed and drained
• 1 cup green or brown lentils, rinsed
• 6 cups vegetable broth
• 1 teaspoon ground cumin
• 1 teaspoon dried oregano
• 1/2 teaspoon smoked paprika
• 1/4 teaspoon crushed red pepper (optional, for heat)
• 1 teaspoon salt (more to taste)
• 1/2 teaspoon black pepper
• 2 cups chopped spinach or kale
• Juice of 1 lemon (for finishing)

How to Make Vegetarian Protein Soup

1. Prepare and Sauté the Vegetables

Start by heating the olive oil in a large soup pot over medium heat. Add the onion, garlic, carrots, celery, bell pepper, zucchini, and mushrooms. Sauté them for about 7 minutes, until the vegetables have softened and start to smell fragrant. Stir every so often so nothing sticks or browns too much.

2. Add Spices and Tomatoes

Next, sprinkle in the cumin, oregano, smoked paprika, crushed red pepper, salt, and black pepper. Stir in the diced tomatoes. Let this cook for another 2 minutes. This step gives a savory flavor base and helps the spices bloom.

3. Add Beans, Lentils, and Broth

Pour in the rinsed chickpeas, black beans, and lentils, then add the vegetable broth. Stir everything together. Bring the pot to a boil, then reduce the heat and keep it at a gentle simmer. Simmer uncovered for 25 to 30 minutes, until the lentils are tender. If you want a slightly thicker soup, mash a few of the beans against the side of the pot as it cooks.

4. Stir in Greens and Lemon

Once the lentils are fully cooked, add the spinach or kale. These greens will wilt quickly, usually within a minute or two. Squeeze in the lemon juice, which brightens the overall flavor, and stir well before serving.

5. Taste and Adjust

Taste the soup and add more salt, pepper, or lemon, if needed. Sometimes I top my bowl with fresh herbs or a sprinkle of nutritional yeast for an extra hit of flavor. For more richness, you can swirl in a small drizzle of olive oil or add a handful of chopped fresh parsley.

Tips and Easy Variations

• For a bigger protein boost, stir in a handful of cooked quinoa or farro during the last five minutes of simmering.
• If you’re missing one type of bean, double up with another kind. Kidney beans, cannellini beans, or pinto beans all work just as well.
• Chopped sweet potatoes or regular potatoes add heartiness and texture if you want a thicker, stew-like soup.
• If you like some heat, add extra red pepper flakes or a splash of your favorite hot sauce right at the end.
• Leftover soup keeps perfectly in the fridge for up to five days, or freeze single servings for easy grab-and-go lunches or dinners.

To make meal prep even simpler, chop your vegetables ahead of time and store them in airtight containers in your fridge. That way, when it’s time to cook, everything comes together quickly. You can even mix in precooked grains, like brown rice, for more fiber and substance.

Serving Suggestions

This soup is a satisfying meal on its own, but it also pairs nicely with crusty bread or a simple green salad for an all-in-one, balanced dinner. If you want an extra-protein meal, add a scoop of plain Greekstyle yogurt (for a vegetarian version) or swirl in pureed silken tofu for a creamy, plantbased twist. Garnishing each bowl with a wedge of lemon or a tiny splash of vinegar boosts the brightness and brings out the flavors. Fresh herbs like parsley, basil, or cilantro are an excellent finishing touch to make the soup visually appealing and a tad fancier.

Common Questions About Vegetarian Protein Soup

Q: Is this soup glutenfree?

A: Yes, the recipe as written is glutenfree. Just make sure to serve it with glutenfree bread if you’re watching your gluten intake.

Q: Can I use dried beans instead of canned?

A: Yes, you can. You’ll need to soak and cook your dried beans ahead of time so they’re tender by the end of cooking. It adds a step or two, but it’s worth it if you have the time and dried beans in the pantry.

Q: How much protein is in each bowl?

A: With beans, lentils, and veggies combined, one serving of this soup typically delivers about 14 to 18 grams of protein. Add in some cooked quinoa or extra tofu, and the number goes up for those seeking even more protein.

Q: Can I make this soup in a slow cooker?

A: Absolutely. Just add everything except the spinach and lemon to your slow cooker and cook on low for 6 to 7 hours, or high for about 3 to 4 hours. Add spinach and lemon juice in the last 10 minutes so the greens wilt but stay fresh.

Q: Can I make it spicy?

A: If you’re looking for more of a kick, toss in extra red pepper flakes, a chopped fresh chili, or a few dashes of hot sauce before serving. You can easily control the spice level to suit your own taste.
