I made a lentil soup last Friday, with stock, lentils, onions and veggies. Is it still good to eat today, 5 days later? It's just been sitting in the fridge for that long.
Are you channeling your best self with this comment? (If you're not sure, check out our Code of Conduct.)
I think it should be fine. But if you don't finish it today, I would freeze it in single-serving portions, either in freezer-safe containers or small freezer bags.
I second what Mrs. Larkin said.
When you heat the soup, bring to a point just short of boiling, for an extra measure of caution. If it has gone 'off' you can tell -- by sight and by smell, or a drop on the tongue. If you have meat or meat broth in the soup, there is less margin of error than for a meat-free soup.
I have a five day rule for anything left over.
Fun to say, delicious to eat.
