Make-Ahead Instructions & Storage
Make-Ahead Tips
Simmer lentils as instructed, then cool completely before storing. For easier portions, spoon into single-serving containers before freezing.
Refrigerator Storage
Keep in an airtight container for up to 5 days. Soup thickens in cold storage—thin with a splash of broth or water before reheating.
Freezer Storage
Freeze in 1–2-cup portions for up to 3 months. Let thaw in fridge overnight before reheating on stove or microwave.
Reheating Instructions
Gently heat on stove over medium-low, stirring occasionally. If soup is too thick, add water or broth as needed.
Troubleshooting & Common Questions
Q: My soup is too thick—can I add water?
A: Absolutely! Lentil soup thickens as it cools. Thin with water, broth, or coconut milk while reheating—it won’t impact flavor negatively.
Q: Can I use yellow or green lentils?
A: Yes, but skin-on green or yellow lentils hold their shape better. Use ½ cup like recipe. They’ll add a firmer bite to the soup.
Q: What if I forgot to rinse the lentils?
A: No problem! This soup doesn’t require rinsing, but it won’t hurt either. Skins help create the smooth texture in cooked soup.
Q: How do I store leftovers with cilantro?
A: Add fresh cilantro just before serving. Stored soup can oxidize, making herbs brown—we always stir in fresh garnish last.
