When making this savory Instant Pot tomato basil lentil soup, you will need a few key ingredients. First, the lentils are the heart of the dish. They add both nutrition and texture. You can use green or brown lentils, depending on your preference.
Next, diced tomatoes bring a rich flavor. They add both sweetness and acidity. I prefer canned tomatoes for their convenience, but fresh can work too.
Onion is vital for a solid flavor base. Finely diced, it becomes sweet and soft when cooked.
Aromatic vegetables are essential for depth. Carrots add natural sweetness, while celery gives a nice crunch. Both enhance the soup's overall taste.
For broth, vegetable broth is best. It keeps the soup light yet flavorful. You can use low-sodium for a healthier option.
Garlic adds a punch of flavor. Minced, it releases its oils and becomes fragrant. Dried herbs like basil and oregano bring a classic taste to the dish.
Lastly, balsamic vinegar and olive oil add richness. Salt and pepper balance the flavors. Together, these ingredients make a comforting bowl of soup that warms you up.

Step-by-Step Instructions
Preparing the Aromatics
First, set your Instant Pot to sauté mode. Add 1 tablespoon of extra virgin olive oil. Let it heat for a moment. Then, add 1 medium diced onion, 2 diced carrots, and 2 diced celery stalks. Sauté them for 5-7 minutes until they are tender. The smell will fill your kitchen! After that, add 4 minced garlic cloves and sauté for another minute. The garlic should become fragrant and golden.
Combining Ingredients
Next, it’s time to build the soup. Pour in 1 cup of thoroughly rinsed lentils. Add 1 can of diced tomatoes, including their juice. Then, pour in 4 cups of vegetable broth. Add 1 tablespoon of balsamic vinegar, 2 teaspoons of dried basil, and 1 teaspoon of dried oregano. Don’t forget to season with salt and black pepper. Stir all the ingredients well to combine them.
Cooking the Soup
Now, close the Instant Pot lid securely. Make sure the steam release handle is in the sealing position. Select the manual or pressure cook setting on high pressure. Set the timer for 15 minutes. Once it finishes, let the pressure release naturally for about 10 minutes. Then, perform a quick release for any remaining pressure.
Finishing Touches
Carefully open the lid and stir the soup. Taste it and adjust the seasoning if needed. For a creamier texture, use an immersion blender. Blend a portion of the soup until you reach your desired smoothness. Serve the soup hot, garnished with fresh basil leaves for extra flavor and color.
Tips & Tricks
Enhancing Flavor
To make your soup even better, try adding spices. You can use smoked paprika for a smoky taste. A pinch of red pepper flakes gives it a kick. Fresh herbs like thyme or parsley also work well. You can swap dried basil for fresh basil to boost flavor. Mixing different herbs adds depth to the taste.
Perfecting Texture
If you want a smooth soup, use an immersion blender. Blend just half of the soup for a creamy feel. You can also add a splash of coconut milk for richness. If you like a chunky soup, skip the blending. This gives you a hearty texture with visible lentils and veggies.
Serving Suggestions
For a great presentation, serve the soup in warm bowls. Drizzle some olive oil on top and sprinkle fresh basil for color. Pair this soup with crusty bread or a fresh salad. A side of garlic bread is always a hit. You can also top it with grated cheese for extra flavor.
Pro Tips
- Use Fresh Herbs: Fresh basil added at the end enhances flavor significantly compared to dried herbs.
- Adjust Consistency: For a heartier soup, blend only half the soup, leaving some lentils whole for texture.
- Flavor Boost: A squeeze of fresh lemon juice before serving adds brightness to the soup.
- Meal Prep Friendly: This soup stores well in the fridge for up to a week or can be frozen for longer storage.
Variations
Vegetarian and Vegan Options
If you want to make this soup vegetarian or vegan, it's easy. The main ingredients are already plant-based. To enhance flavor, use vegetable broth instead of chicken broth. You can also swap the balsamic vinegar for apple cider vinegar. This adds a tangy taste without any animal products. If you want a creamy texture, try adding unsweetened almond milk or coconut milk.
Adding Protein
Looking to add protein? You have options. For meat lovers, diced chicken or sausage works well. Sauté the meat with the vegetables for extra flavor. If you prefer plant-based protein, consider adding cooked quinoa or chickpeas. Both options boost protein without changing the soup's essence. Just stir them in before serving for a hearty meal.
Customizing Vegetables
Feel free to get creative with your vegetable choices. You can add seasonal veggies like zucchini, bell peppers, or spinach. Just chop them into small pieces and add them when you add the lentils. This not only adds color but also extra nutrients. Mixing in your favorite vegetables makes the soup truly yours.
Storage Info
Storing Leftovers
After you enjoy your soup, store leftovers in an airtight container. Let the soup cool first. Refrigerate it for up to five days. For longer storage, freeze the soup. Use freezer-safe containers or bags. It can last for three months in the freezer. Just remember to label your containers with the date!
Reheating Tips
To reheat your soup, pour it into a pot. Heat it on medium until it simmers. Stir occasionally to keep it from sticking. If it’s too thick, add a splash of broth or water. You can also use the microwave. Place the soup in a microwave-safe bowl. Cover it loosely and heat in short bursts, stirring in between.
Shelf Life
The soup lasts well in the fridge for five days. If frozen, it stays fresh for three months. After that, the flavor may fade. Always check for any off smells or changes in texture before you eat. If it looks or smells odd, it’s best to toss it. Enjoy your hearty soup while it’s at its best!
