Step-by-Step Instructions

Let’s get cooking! This process is straightforward and rewarding.

1. Sauté the Aromatics: Heat the olive oil in a large stockpot or Dutch oven over medium heat. Add the diced onion, carrots, and celery. Cook, stirring occasionally, until the vegetables soften, about 5-7 minutes.
2. Add Garlic and Tomato Paste: Stir in the minced garlic and tomato paste. Cook for one more minute until the garlic is fragrant. This step builds a deep flavor base for your High Protein Lentil Soup.
3. Combine Soup Ingredients: Add the rinsed lentils, vegetable broth, diced tomatoes with their juices, dried thyme, and the bay leaf to the pot. Give everything a good stir to combine.
4. Simmer to Perfection: Increase the heat and bring the soup to a boil. Then, immediately reduce the heat to low, cover the pot, and let it simmer gently for 30-40 minutes. The lentils should be tender but not mushy.
5. Final Seasoning: Remove the pot from the heat. Take out the bay leaf and discard it. Season your High Protein Lentil Soup generously with salt and black pepper. Taste and adjust the seasoning as needed.

Pro Tips for Success

Follow these simple tips for the absolute best results every single time. Always rinse your lentils thoroughly before using them. This removes any debris or dust. Do not skip sautéing the vegetables. This crucial step, called “sweating,” develops a wonderful sweetness and depth. If your soup seems too thick after cooking, simply add a little more broth or water until it reaches your desired consistency. Conversely, if it’s too thin, let it simmer uncovered for a few more minutes to reduce. For an extra creamy texture, you can use an immersion blender to partially puree the soup right in the pot. Let the soup rest for 10-15 minutes after cooking. This allows the flavors to meld together beautifully, making your High Protein Lentil Soup even more delicious.

Storage & Reheating Tips

This High Protein Lentil Soup stores wonderfully, making it a fantastic make-ahead meal. Allow the soup to cool completely before storing. Then, transfer it to an airtight container. You can keep it in the refrigerator for up to 4-5 days. To freeze, portion the cooled soup into freezer-safe bags or containers. It will keep well for up to 3 months. Thaw frozen soup overnight in the refrigerator before reheating. To reheat, simply warm it in a pot on the stove over medium heat, stirring occasionally, until hot. You can also reheat single portions in the microwave. The lentils will continue to absorb liquid, so you may need to add a splash of broth or water when reheating to get the perfect soup consistency again.

What to Serve With This High Protein Lentil Soup

This hearty High Protein Lentil Soup is a meal in itself, but it pairs beautifully with a few simple sides. A thick, crusty slice of whole-grain bread or a warm, buttery dinner roll is perfect for dipping and soaking up every last drop. For a fresh contrast, serve it with a simple side salad dressed with a light vinaigrette. You could also top your bowl with a dollop of plain Greek yogurt or sour cream for a cool, creamy element. A sprinkle of fresh chopped parsley or cilantro on top adds a pop of color and freshness. For a more substantial meal, you could even serve it over a small bed of cooked quinoa or brown rice. This High Protein Lentil Soup is truly the star of the show.
