Storage Tips

Refrigerator: Cool soup to room temperature within 2 hours. Transfer to airtight containers and refrigerate up to 5 days. The flavor actually improves on day two as spices meld.

Freezer: Ladle completely cooled soup into quart-size freezer bags, squeeze out excess air, label, and freeze flat on a sheet pan. Once solid, stack vertically to save space. Keeps 3 months for peak quality; 6 months is safe but texture may degrade.

Reheating: Thaw overnight in the fridge or use the microwave’s defrost setting. Warm gently on the stovetop over medium-low, thinning with broth or water until pourable. Avoid rapid boiling, which turns lentils mushy and spinach drab.

Make-ahead lunches: Portion into 2-cup mason jars; add a layer of uncooked spinach on top. When microwaved, the spinach wilts perfectly without becoming overcooked.

Frequently Asked Questions

Do I need to soak lentils first?

No soaking required for brown or green lentils. A quick rinse to remove dust and debris is sufficient. Soaking can actually cause them to burst and lose shape.

Can I use red lentils?

Red lentils cook much faster and break down into a creamy dal-like consistency. If that’s your goal, reduce simmering time to 15 minutes and skip the blending step.

How do I fix over-salted soup?

Drop in a peeled potato and simmer 10 minutes; it will absorb some salt. Alternatively, dilute with unsalted broth or add another cup of cooked lentils and tomatoes to increase volume.

Is this soup gluten-free?

Yes, all ingredients are naturally gluten-free. Always check labels on broth and tomato products to confirm no hidden wheat-based additives.

Can I double this in a 6-quart Instant Pot?

Absolutely—use sauté function for steps 1–3, then pressure cook on high for 12 minutes with natural release 10 minutes. Stir in spinach and lemon juice after opening.

What protein pairs well if I’m not vegan?

Top with a poached egg, seared shrimp, or crumbled feta. For meat lovers, browned Italian sausage or shredded rotisserie chicken stirred in at the end complements the smoky paprika.
