Step by Step Cooking Instructions
- Prepare all vegetables
Wash, peel, and dice the onion, carrot, celery, red bell pepper, and zucchini. Mince the garlic cloves. Chop parsley in advance so it is ready when needed. Having everything prepped ensures smooth flow during cooking. - Heat oil and sauté aromatics
In a large soup pot place the olive oil over medium heat. Add the diced onion, carrot, and celery. Stir gently and let them soften, about 5 to 7 minutes. Add the minced garlic and stir for an additional 1 minute until fragrant. Avoid browning or burning the garlic by keeping heat moderate. - Add bell pepper and zucchini
Stir in the diced red bell pepper and zucchini pieces. Cook for 3 to 4 minutes, stirring occasionally. The edges will begin to soften but maintain some structure. This step builds depth of flavor before liquid arrives.Fans of this recipe will definitely enjoy Winter Soup_ too. - Add tomatoes, broth, and lentils
Pour in the canned diced tomatoes (including liquid) and the vegetable broth. Stir to combine. Add the red lentils now. Sprinkle in dried thyme or oregano. Bring the mixture to a gentle boil over medium high heat. - Simmer until tender
Once boiling, reduce heat to low or medium low and cover partially. Let the soup simmer for about 20 to 25 minutes. The lentils should soften and vegetables become tender but not mushy. Stir occasionally and check if more liquid is needed. Adjust consistency with a little extra broth or water if soup becomes too thick. - Add spinach and parsley
After main components are cooked, stir in baby spinach leaves and chopped parsley. The residual heat wilts spinach in just a few minutes. Taste and adjust salt and black pepper. If desired, stir in fresh lemon juice to brighten flavors. - Optional blending or leaving chunky
You may leave the soup chunky or partially blend it for a thicker texture. Use an immersion blender to purée a portion or whole, depending on preference. If blending, do so carefully and gradually, retaining some chunks for mouthfeel. - Final seasoning and serve
Taste the soup a final time. Adjust seasoning. If flavor feels flat, a small pinch of salt or a dash of lemon juice can lift the profile. Ladle into bowls and garnish with extra parsley if desired.

Tips for Customizing the Recipe
- Swap or add vegetables based on season or what you have. For example, diced sweet potato, squash, green beans, or mushrooms all work well.
- Use split peas or small pasta shapes instead of lentils for variation.
- For creaminess without dairy, stir in a small amount of cashew cream or coconut milk at end.
- Try other fresh herbs such as basil, cilantro, or dill in place of parsley for flavor change.
- Spice it up by adding red pepper flakes, smoked paprika, or a pinch of cayenne.
- For bulk and protein, include cooked beans such as cannellini or chickpeas.
- If you prefer a thinner broth, increase the broth or water ratio.
- For richer mouthfeel, swirl in a tablespoon of olive tapenade or pesto just before serving.
- Make ahead tip: the soup often tastes better the next day. Reheat gently and add spinach fresh.
- Freeze leftovers in freezer safe containers, leaving some room for expansion. When thawing, add fresh herbs and lemon juice.

Serving Suggestions
Serve the vegetarian soup piping hot in wide soup bowls. A crusty whole grain bread or warm baguette complements beautifully and helps to soak up the broth. A side of mixed green salad dressed lightly with olive oil and lemon works as a fresh contrast. Garnish with extra chopped parsley or a drizzle of high quality olive oil. For a heartier meal, accompany the soup with whole grain crackers, roasted vegetables, or a slice of savory vegetable loaf. Add a small dish of grated cheese or vegan cheese on the side for those who enjoy sprinkling it on top. A wedge of lemon or lime per bowl allows guests to brighten their soup individually.

Frequently Asked Questions
Can I make this soup in a slow cooker or crock pot?
Yes you can. Begin by sautéing the aromatics separately or in the base of a slow cooker (if it allows). Then transfer all ingredients including vegetables, broth, tomatoes, lentils to the slow cooker. Cook on low for 6 to 8 hours or high for 3 to 4 hours. Add spinach and parsley near the final half hour to preserve freshness.
Is it possible to make the soup gluten free?
Absolutely. The recipe as written contains no gluten. Just ensure the vegetable broth or stock you use is certified gluten free and avoid adding pasta or bread that contain gluten.
Can I use fresh tomatoes instead of canned?
You may replace canned diced tomatoes with about 3 to 4 fresh ripe tomatoes, peeled and chopped. The soup will be a bit lighter in body and flavor may shift slightly, but it will still be delicious.
How long does the soup keep in the refrigerator or freezer?
Stored in an airtight container in the refrigerator, the soup keeps well for 4 to 5 days. In the freezer it lasts up to 2 months. Defrost overnight in refrigerator, then gently reheat on stovetop, adding fresh spinach or herbs at reheating time.
Is it possible to increase the protein content further?
Yes. You may stir in cooked beans such as cannellini beans, chickpeas, or edamame. You could also incorporate tempeh or tofu cubes. Another idea is to add a scoop of cooked quinoa or bulgur toward the end of cooking.
Can I omit lentils entirely? What would be a substitute?
You may omit lentils but be prepared for the soup to lose some body and protein. Substitute with small pasta shapes, barley, or diced potatoes to restore heartiness.
