Technique Tip for This Recipe
When sautéing the onion and garlic, make sure to cook them until they are translucent and fragrant. This step is crucial as it forms the flavor base for the soup. Stirring constantly when adding the spices ensures they do not burn and release their full aroma. When simmering the lentils, keep an eye on the liquid level; you may need to add a bit more vegetable broth if the soup becomes too thick. Adding the lemon juice at the end brightens the flavors, while the fresh cilantro adds a burst of freshness.

How To Store / Freeze This Soup
- Allow the red lentil soup to cool completely before storing. This prevents condensation and helps maintain the texture and flavor.
- Transfer the cooled soup into airtight containers. For easy portion control, consider using individual serving-sized containers.
- Label the containers with the date of preparation. This helps you keep track of freshness and ensures you consume the soup within a safe timeframe.
- Store the containers in the refrigerator if you plan to consume the soup within 3-4 days. The flavors will meld together beautifully, making it even more delicious.
- For longer storage, place the airtight containers in the freezer. The soup can be frozen for up to 3 months without losing its quality.
- When ready to enjoy, thaw the soup in the refrigerator overnight. This gradual thawing helps maintain the soup's texture and flavor.
- Reheat the soup on the stovetop over medium heat, stirring occasionally. You can also use a microwave, heating in short intervals and stirring in between to ensure even heating.
- If the soup appears too thick after reheating, add a splash of vegetable broth or water to reach your desired consistency.
- Garnish with fresh cilantro and a squeeze of lemon juice before serving to revive the fresh flavors.
How To Reheat Leftovers
Stovetop Method: Pour the leftover soup into a pot. Heat over medium-low heat, stirring occasionally to ensure even warming. Add a splash of vegetable broth if the soup has thickened too much. Heat until the soup is steaming and hot throughout, about 5-10 minutes.
Microwave Method: Transfer the soup to a microwave-safe bowl. Cover with a microwave-safe lid or a microwave-safe plate to prevent splatters. Heat on high for 2-3 minutes, stirring halfway through. If the soup isn't hot enough, continue heating in 30-second intervals, stirring in between, until thoroughly heated.
Slow Cooker Method: Place the leftover soup in a slow cooker. Set it to low heat and let it warm for 1-2 hours, stirring occasionally. This method is perfect if you have time and want to keep the soup warm for an extended period.
Oven Method: Preheat your oven to 350°F (175°C). Transfer the soup to an oven-safe dish and cover with foil. Heat for about 20-30 minutes, stirring halfway through, until the soup is hot throughout. This method is ideal if you're reheating a large batch.
Double Boiler Method: Fill a large pot with a couple of inches of water and bring it to a simmer. Place a heatproof bowl with the soup over the simmering water, ensuring the bottom of the bowl doesn't touch the water. Stir occasionally until the soup is heated through. This gentle method helps prevent the soup from sticking or burning.
