Chard, Lentil & Potato Slow Cooker Soup Recipe (1)

I own a ton of cookbooks, but if I had to choose the one I use the most often in my kitchen, it's Fresh from the Vegetarian Slow CookerChard, Lentil & Potato Slow Cooker Soup Recipe (2) by Robin Robertson. This is my book that has notes scrawled all over the pages and food spatters on the most frequently used recipes. If you're a vegetarian and you own a slow cooker, you should really buy this book!

This recipe is adapted from a kale and lentil soup that's in Fresh from the Vegetarian Slow Cooker.Chard, Lentil & Potato Slow Cooker Soup Recipe (3) It's not super fancy, it's not a show-stopper, but it's a delicious, hearty soup for a chilly fall evening. I replaced the kale with chard—and used a lot more than the original recipe calls for. We love Swiss chard, and if I was buying a whole bunch anyway, why not use it? I even threw in the stems, so nothing goes to waste! I also added some Yukon potatoes to make this soup even more filling, but sweet potatoes or butternut squash would probably be just as tasty.

Why do you love this cookbook?

The thing I love about Fresh from the Vegetarian Slow Cooker is that the recipes are mostly unfussy. You might have to sauté some ingredients before putting them in the crockpot. But other than that, things are pretty uncomplicated—which is what I like in a cookbook. I want realistic, everyday meals. I want a cookbook I can use, not one with lots of pretty pictures of recipes that are a such pain to assemble that I'll probably never make.

When I was working full-time and going to library school full-time (yeah, that happened), I worked my way through a good half of the recipes in this cookbook. They were so easy to put together! I could let them cook in the crockpot all day and dinner would be ready when we got home. Without fail, they were all winners. The best part was that there were always leftovers, so we could have them for dinner the next day or freeze them. The only thing easier than a slow cooker meal is a leftover meal! Or stopping at Chipotle on the way home from work. (Yeah, that happened too.)

Can I freeze this soup?

You can easily freeze this soup. Simply let it cool down a bit, pour it into freezer-friendly containers or ziplock bags, and pop it in the freezer until you're ready to eat it again! I recommend separating the soup into serving-size portions so you don't have to thaw all of your frozen soup when you only want to eat one cup.

FAQs

Do I need to rinse lentils before making soup? ›

Rinse. On occasion, you'll find small rocks or debris mixed in with dried lentils. To avoid eating them, rinse the lentils in a fine mesh sieve and pick them over before you cook them.

Can you overcook lentil soup? ›

Yes, you can overcook lentils; they will become mushy. Much depends on the type of lentil you're using. Some cook quicker and hold their shape better than others. To avoid overcooking them, always follow the cooking directions in your recipe and use the type of lentils called for in the ingredient list.

Why is my lentil soup not thick? ›

Cook It Longer

Sometimes soup just needs to simmer longer to reach the perfect consistency. Check to see if the vegetables are tender, and then taste the broth. If the soup tastes a bit watery, give it more time.

Does soup taste better in slow cooker? ›

Slow cookers can transform a few simple ingredients into the most delicious soups by simmering them for hours. This low and slow cooking allows the flavors to mingle, creating rich, flavorful soups perfect for chilly days, nights, or any day you want to enjoy a bowl full of goodness.

Which color lentils are best for soup? ›

Red lentils are best for soups, curries, dals, and anything that craves a creamy, thicker, more comforting touch. Red lentils are some of our favorites around here, especially our newest Ethiopian inspired lentils!

What happens if you don't pre soak lentils? ›

Soaking: Unlike beans, lentils are small and cook relatively quick (in general, about 20-30 minutes) so they don't require pre-soaking. However, soaking lentils for a few hours or overnight may improve the digestibility of starches in lentils and an overnight soak can also reduce cooking time by about half.

What makes lentils taste better? ›

Think more like you're cooking pasta- you just need significantly more water than lentils. You can also use broth instead of adding an extra layer of flavor. I like adding a bay leaf, an onion cut in half, and a clove of garlic to add flavor to the lentils.

Is too much lentil soup bad for you? ›

Eating half a cup of cooked lentils gives you lots of essential nutrients and their high fiber content makes you feel full. However, the fiber in lentils can be hard for your body to break down. Eating too many lentils can cause gas, bloating, and cramping.

What happens if you forget to rinse lentils? ›

While it seems like an unnecessary step, don't skip rinsing your lentils and sifting through them before cooking to remove any stones or debris. It is rare to find stones, but it does happen.

Why did my lentil soup turn black? ›

the color change you've observed is from oxidation. If you want to prevent this, lay some plastic wrap over the surface of your lentils to prevent air from getting to them, or add some acid, like lime juice, to the recipe.

What is the foam on top of lentil soup? ›

That means the foam will typically appear when making meat-based broths and, to a lesser degree, soups made from high-protein vegetables such as chickpeas and lentils. When those coagulated proteins cluster together, they can create air pockets, which is what causes the “sudsy bubbles,” says Trout.

What is the white foam on lentil soup? ›

The outer layer of the lentil contains saponins, which are natural compounds that can create foam when agitated. When the lentils are split or hulled, the outer layer is removed, which can cause the saponins to be released more easily and contribute to foam formation.

Do you stir soup in slow cooker? ›

Due to the nature of a slow cooker, there is no need to stir the food unless it specifically says to in your recipe. In fact, taking the lid off to stir food causes the slow cooker to lose a significant amount of heat, extending the cooking time required. Therefore, it is best not to remove the lid for stirring.

How long is too long for slow cooker soup? ›

Recipes with meat like chili and pork shoulder are best when cooked for six hours minimum or up to ten hours. Vegetarian recipes are best cooked for around four hours, but can do a minimum of two hours or maximum of six hours (after which the vegetables start to get unpleasantly mushy).

What size slow cooker is best for soup? ›

If you're cooking for yourself or for only two people, a 2 1/2 to 3 1/2-quart slow cooker might be large enough. It's great for smaller amounts of soups and stews. Many slow cooker recipes are written for 6-quart models and can simply be halved for this size.

Is it bad not to rinse red lentils? ›

Lentils do not require it but can be soaked in order to reduce cooking time by about half. Before cooking, rinse lentils in cold water, pick over to remove debris or shrivelled lentils, then drain.

Do you need to rinse a can of lentils? ›

Do you rinse canned lentils? It is not necessary to rinse canned lentils before cooking, but you can rinse them by emptying them into a strainer and under cold water. This can help to remove some of the sodium content from the liquid around the beans.

How long to rinse lentils before cooking? ›

Swish the water, drain, and repeat until the water runs clear. This usually takes six or seven rinses for red lentils, split peas and moong dhal, and as little as two for green or brown lentils.
