Crockpot Lentil & Sweet Potato Stew Recipe FAQs

What type of lentils should I use for the stew?
I recommend using dried brown lentils because they hold their shape well during slow cooking and absorb flavors beautifully. Avoid red lentils here as they tend to become mushy, losing that hearty texture you want in this stew.

How long can I keep the stew in the fridge?
You can safely store your Crockpot Lentil & Sweet Potato Stew in an airtight container in the refrigerator for up to 4 days. Be sure to let it cool completely before sealing to maintain freshness and avoid bacterial growth.

Can I freeze Crockpot Lentil & Sweet Potato Stew?
Absolutely! Freeze it in portioned, freezer-safe containers with some room left for expansion. For best flavor and texture, freeze for up to 3 months. When ready, thaw overnight in the fridge and gently reheat on the stove, adding a bit of broth if it thickens too much.

My sweet potatoes turned mushy, what did I do wrong?
Sweet potatoes can become mushy if cut too small or cooked too long. I suggest cutting them into uniform, medium-sized cubes and sticking to the recommended slow cooker times (6–8 hours low or 3–4 hours high). Stir gently to avoid breaking them apart during cooking.

Is this stew safe for pets?
This stew contains onions and garlic, which can be harmful to dogs and cats, so I advise against sharing it with your furry friends. Instead, treat them to pet-specific meals designed for their dietary needs to keep everyone happy and healthy!
