– 3 celery stalks, diced – Classic mirepoix for depth
– 4 garlic cloves, minced – Pungent base that mellows during cooking
– 1 can (14 oz) diced tomatoes – Provides acidity and body

Prep Time & Cooking Schedule
– Prep Time: 15 minutes (chopping vegetables, rinsing lentils)

– Resting Time: 10 minutes after cooking (flavors deepen)
– Total Time: Approximately 1 hour

Step-by-Step Instructions
1. Prepare the Base
Heat 2 tablespoons olive oil in a large pot over medium heat. Add diced onion, carrots, and celery. Sauté for 6–8 minutes until softened and lightly golden, stirring occasionally. This builds the flavor foundation for your Lentil Soup.
2. Build Aromatics
Add minced garlic, cumin, and smoked paprika. Stir constantly for 30–60 seconds until fragrant—be careful not to burn the garlic. The aroma should fill your kitchen.
3. Combine Key Ingredients
Pour in the rinsed lentils, diced tomatoes (with juices), and broth. Tip: Hold off on salt at this stage—salt can toughen lentils if added too early. Bring to a gentle boil, then reduce heat to low and simmer partially covered for 25–30 minutes, or until lentils are tender but not mushy.
4. Season and Finish
Once lentils are cooked, stir in 1–2 tablespoons fresh lemon juice—this brightens the entire dish. Season with salt and black pepper to taste. For a creamier Vegetarian Lentil Soup, use an immersion blender to purée about half the soup directly in the pot, then stir to combine. This creates a velvety texture without removing the hearty chunks.
5. Rest and Serve
Remove from heat and let rest for 10 minutes. Ladle into bowls, garnish with fresh parsley and a drizzle of olive oil, and serve with crusty bread or a side salad.

Common Mistakes to Avoid

| Skimping on aromatics | Sauté vegetables thoroughly—don’t rush this step |
| Forgetting acidity | Always finish with lemon juice or vinegar to brighten flavors |

Storage & Meal Prep Tips
Refrigeration: Cool soup completely before transferring to airtight containers. Store in the refrigerator for up to 5 days. The soup thickens as it sits—thin with a splash of broth or water when reheating.
Freezing: Portion into freezer-safe containers or zip bags (lay flat to save space). Freeze for up to 3 months. Thaw overnight in the refrigerator before reheating.
Reheating: Warm gently on the stovetop over medium-low heat, stirring occasionally. Add a squeeze of fresh lemon juice after reheating to refresh the flavor. Avoid microwaving at full power, which can make lentils rubbery.
Meal Prep Tip: Make a double batch on Sunday for lunches all week. Store individual portions with a wedge of lemon and fresh herbs separate from the soup until serving.

FAQs
1. Can I use red lentils instead of brown?
Yes, but red lentils break down completely, resulting in a creamy, almost puréed texture. Reduce cooking time to 15–20 minutes and watch carefully to avoid scorching.
2. Why is my lentil soup bland?
Most likely you need more acidity and salt. Add an extra tablespoon of lemon juice and adjust seasoning gradually. Also ensure you sautéed aromatics sufficiently—pale vegetables mean less flavor.
3. Can I make this soup without oil?
Absolutely. Sauté vegetables in 2 tablespoons of water or vegetable broth, adding more as needed to prevent sticking. The flavor will be slightly different but still delicious.
4. How do I adjust the consistency?
For thicker soup: remove lid in the last 10 minutes to evaporate excess liquid. For thinner soup: add extra broth or water in ¼-cup increments until desired thickness.
5. Can I add meat to this recipe?
Yes, though it will no longer be vegetarian. Sauté ½ pound of cooked Italian sausage or diced bacon before adding vegetables, and use chicken broth for a heartier version.
