Lentil and Sweet Potato Stew with Kale

What to keep in mind.
6 tips from the recipe — small details that make a real difference to the final dish.
- 1Rinse the lentils thoroughly to remove any debris and reduce foaming during cooking.
- 2Cut sweet potato chunks evenly so they cook at the same rate as the lentils.
- 3Don't skip sweating the onions, carrots, and celery—this builds a deep flavor base.
- 4Add water gradually if the stew thickens too much; you want a spoonable, not pasty, consistency.
- 5Stir in kale just until wilted—overcooking makes it mushy and dulls its color.
- 6Let the stew rest for 5 minutes off heat to let flavors meld and thicken naturally.
