Chefs Helpful Tips

• Rinse the lentils – Always rinse lentils before cooking to remove any debris and improve texture.
• Sauté aromatics first – For deeper flavor, sauté the onion, garlic, and celery in a pan before adding them to the slow cooker.
• Use low-sodium broth – Control the salt levels by using low-sodium vegetable broth, then adjust seasoning to taste.
• Layer the ingredients – Place heartier vegetables like carrots and celery at the bottom of the slow cooker for even cooking.
• Don’t overcook the lentils – Check for doneness toward the end of the cooking time to avoid mushy lentils.
• Add greens at the end – Stir in fresh spinach or kale during the last 10 minutes for added nutrients and color.
• Blend for a creamy texture – For a creamier soup, blend a portion of the soup with an immersion blender or regular blender.
• Adjust seasoning last – Always taste and adjust seasoning after the soup has finished cooking for the best flavor balance.
• Freeze for later – This soup freezes well, so make extra and store in freezer-safe containers for future meals.
