Frequently Asked Questions
Can I use frozen kale in lentil soup?
Yes, frozen kale works well in lentil soup. Add it directly from frozen during the final 10 minutes of cooking. No need to thaw—this prevents excess water release. Frozen kale often retains more nutrients than store-bought fresh kale that's been transported long distances.
How do I fix bland lentil kale soup?
Revive bland soup with layered seasoning: First, add 1 tbsp lemon juice or apple cider vinegar to brighten flavors. Next, incorporate 1 tsp smoked paprika or 2 strips of crumbled tempeh bacon for depth. Finally, finish with flaky sea salt and freshly cracked pepper. Taste and adjust after each addition for balanced flavor.
Which lentils work best for soup?
French green lentils (Puy) hold their shape best for soup texture. Brown lentils work well but become softer. Avoid red lentils if you prefer distinct lentil pieces—they dissolve completely, creating a creamier texture ideal for pureed soups. For meal prep, green lentils maintain better texture after reheating.
Can I make lentil kale soup in a slow cooker?
Absolutely. Sauté aromatics first, then transfer to slow cooker with lentils and broth. Cook on low 6-7 hours or high 3-4 hours. Add kale during the last 30 minutes to preserve texture and nutrients. The slow cooking method enhances flavor development while maintaining nutritional value.
