Ingredients
Complete List of Ingredients
To make this savory soup, gather these ingredients:
- 1 cup dried green or brown lentils, rinsed
- 1 can (14 oz) diced tomatoes, with juice
- 1 medium onion, diced
- 2 carrots, diced
- 2 celery stalks, diced
- 4 cups vegetable broth
- 4 cloves garlic, minced
- 1 tablespoon olive oil
- 1 tablespoon balsamic vinegar
- 2 teaspoons dried basil
- 1 teaspoon dried oregano
- Salt and pepper to taste
- Fresh basil leaves for garnish
Each ingredient plays a key role. Lentils add protein and fiber. Tomatoes bring acidity and sweetness. Fresh herbs enhance the flavor.
Fresh vs. Dried Herbs
You can use fresh or dried herbs. Dried herbs have a strong flavor and are easy to store. Fresh herbs offer bright taste and aroma. If using fresh basil, add it at the end for the best flavor. For dried herbs, mix them in with the other ingredients when cooking.
Substitute Options for Lentils and Broth
If you need to replace lentils, try split peas or chickpeas. These options offer a similar texture. For broth, vegetable broth is preferred, but chicken broth works too. You can even use water if you have no broth on hand. Just remember to adjust the seasoning to keep the flavor strong.

Step-by-Step Instructions
Sautéing Vegetables in the Instant Pot
Start by setting your Instant Pot to the sauté mode. Pour in one tablespoon of olive oil. Let it heat up for a moment. Add one diced medium onion, two diced carrots, and two diced celery stalks. Sauté these for about five to seven minutes. You want the veggies to soften and smell good. This step builds the base flavor for your soup.
Combining Ingredients for Flavor
Next, stir in four minced garlic cloves. Sauté for one more minute until you smell the garlic. Now, add one cup of rinsed dried lentils and one can of diced tomatoes, including the juice. Pour in four cups of vegetable broth. Add one tablespoon of balsamic vinegar, two teaspoons of dried basil, and one teaspoon of dried oregano. Season with salt and pepper to your taste. Stir everything well to blend the flavors.
Pressure Cooking Tips for Perfect Texture
Close the Instant Pot lid. Make sure the steam release handle is set to sealing. Choose the manual or pressure cook setting on high for fifteen minutes. Once done, let the pressure release naturally for ten minutes. After that, quick release any remaining pressure. Carefully open the lid and stir the soup. If you want a smoother texture, use an immersion blender to blend part of the soup. Adjust the seasoning if needed before serving. Enjoy your delicious soup!
Tips & Tricks
Achieving the Best Flavor Profile
To make this soup burst with flavor, focus on the fresh herbs. I love using dried basil and oregano for a strong taste. Adding a splash of balsamic vinegar enhances the soup's richness. For even more depth, sauté your veggies until they are golden brown. This builds a great base for the soup.
How to Adjust Consistency
If you like a thick soup, don't add too much broth. Use only what the recipe calls for. If you want a thinner soup, stir in more vegetable broth after cooking. An immersion blender is a great tool if you want to puree part of the soup. This gives you a smooth texture with some lentils still whole.
Making Ahead and Meal Prep Options
You can make this soup ahead of time. It tastes even better the next day! Store it in an airtight container in the fridge for up to five days. For meal prep, divide the soup into portions and freeze it. This way, you always have a warm meal ready when you need it. Just thaw and heat when you're hungry!
Variations
Adding Protein Options
You can boost the protein in this soup. Cooked chicken, turkey, or sausage works well. If you want to keep it plant-based, try adding tofu or tempeh. These options add flavor and texture.
Incorporating Other Vegetables
Feel free to add your favorite veggies. Spinach, kale, or bell peppers mix in nicely. You can also use zucchini or corn for extra sweetness. Just chop them up and add them during the sauté step.
Vegan and Gluten-Free Substitutions
This soup is already vegan and gluten-free. To keep it that way, use vegetable broth and check labels on canned goods. If you want a creamy version, blend in some coconut milk for a rich taste. Adjust spices to suit your taste buds.
Storage Info
Best Ways to Store Leftovers
To keep the soup fresh, let it cool first. Use a clean container with a tight lid. This helps prevent spills and keeps the soup tasty. You can store it in the fridge for up to five days. If you want to eat it later, freezing is a great option.
Reheating Instructions
When you’re ready to enjoy your soup again, reheat it on the stove or in the microwave. If using the stove, pour the soup into a pot. Heat on medium until warm, stirring often. If using the microwave, place the soup in a microwave-safe bowl. Heat in short bursts, stirring in between, until hot. Always check the temperature before serving.
Freezing Tips for Long-Term Storage
For long-term storage, freeze the soup in small portions. Use freezer-safe bags or containers. Make sure to leave some space at the top, as liquids expand when frozen. Label the bags with the date. The soup can stay good for up to three months in the freezer. When you want to eat it, thaw it in the fridge overnight before reheating.
