Instant Pot Lentil Soup Recipe FAQs
How do I know if my lentils are good to use for this soup?
Look for lentils that are dry, firm, and free from dark spots or cracks. Rinse them thoroughly before cooking to remove any dust or small debris. Avoid lentils that appear shriveled or have an off smell.
What’s the best way to store leftover Instant Pot Lentil Soup?
Cool the soup to room temperature, then transfer it into airtight containers. Refrigerate for up to 5 days to keep it fresh and flavorful. For longer storage, freezing is the way to go—just portion it out and freeze within 2 hours of cooking.
Can I freeze Instant Pot Lentil Soup, and how should I do it?
Absolutely! Freeze your soup in airtight, freezer-safe containers or heavy-duty freezer bags. Leave about an inch of space on top for expansion. Label with the date and freeze for up to 3 months. When ready to enjoy, thaw it overnight in the fridge or use a cold water bath for quicker thawing before reheating gently on the stovetop.
What if my soup turns out too thick or too watery?
If it’s too thick, simply stir in a splash of vegetable broth or water when reheating until you reach the desired consistency. If too watery, simmer it uncovered on the stovetop for a few minutes to reduce. Keeping an eye on the pressure cooking time and liquid amounts helps prevent this too!
Is this Instant Pot Lentil Soup safe for pets or people with allergies?
This soup is naturally vegetarian and gluten-free, making it allergy-friendly for many diets.
