What’s the easiest way to fill your freezer?

Make tons of soup, of course!

Soup is an incredibly popular freezer meal, and why not? You throw a bunch of ingredients into a bag- not having to cook it first- and then put it in the freezer for later.

I’ve already made a Sweet Potato Black Bean Chili during this 25 Days of Freezer Meals series, and I figured one more wouldn’t hurt. Not only is this Slow Cooker Lentil Soup an easy dump meal, it’s also vegetarian, which makes it really cheap.

Did you know you can find lentils for around a dollar a bag? Yep, I’ve found 1-pound bags at my local Dollar Tree. I only used about half the bag for this recipe, so 50 cents worth. An amazing deal for a food that’s packed with protein!

Can you add meat to Slow Cooker Lentil Soup?

Sure! Chicken, sliced sausage, or even ground beef would go well in this. If you use ground beef, I recommend cooking it first before adding it to the freezer bag. Meat would help stretch out the meal and give you more servings.

Do you have to soak the lentils before cooking?

Not necessarily. Since you’re slow cooking these, they’ll be cooking for a few hours anyway so it’s not a big deal. You can soak them ahead of time if you plan to make this on the stovetop, which can save time.

Can you cook Lentil Soup first before freezing?

Absolutely! You’ll still cook on high for 4-5 hours. And you can pour the soup into individual containers, or into one or two gallon-sized freezer bags. All you need to do then is thaw in the fridge overnight and heat up on the stove for a few minutes.
