I always make this lentil sweet potato casserole when I want to detox after eating a lot of junk! This is the perfect healthy recipe to make you feel better.

We love this Lentil Sweet Potato Casserole, adapted from Vegetarian Times. The colorful combination of vegetables and lentils is the perfect meal when we want to feel healthy again after we’ve been eating junkier food for a few days. I cut back the amount of curry and garlic, and I make it all in one casserole dish instead of aluminum foil packets. It’s a great combination of spicy and sweet.

This casserole is an easy make-ahead recipe for a busy night. You can prepare the ingredients during the weekend, and then all you need to do is put it in the oven when you’re ready to serve it.

    1. Thanks, Hayley! I actually haven’t tried freezing this, but I don’t see why you couldn’t. Let me know if you try it.

  1. This looks terrific! I am going to try it with butternut squash, since one of my girls can’t eat sweet potatoes. Thanks for sharing!
