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 have to cook lentils before adding to soup? ›

Do you cook lentils before adding to soup? Nope! Dried lentils cook in 35 minutes in the soup, and there's no need to soak them either!

Why is my lentil soup so thick? ›

Go easy—if you purée the soup too much, it will get too thick and you'll lose the integrity of the lentils. If you don't have an immersion blender, transfer a few cups of the soup to a standard blender and purée, then return the blended soup to the pot.

Do lentils soak up broth? ›

Lentils aren't rice—they don't need to absorb every last drop of cooking liquid. They're more like pasta: best cooked in an abundance of water or stock. Bring your liquid up to a boil, add your lentils, then turn down your heat to a simmer for at least 25-30 minutes.

Can you overcook lentils in 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.

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 is my lentil soup tasteless? ›

Maybe try adding some salt for better flavour. The only type of lentils you shouldn't have is raw lentils, since that would probably make you sick. What are some simple recipes with lentils that don't taste bland? I love lentil soup with different spice blends, like yellow curry or Harissa.

What is the white stuff in lentil soup? ›

Those look to be radicles (embryonic stems, the part the root grows from) that have separated from the lentils. If you look closely at the less squished lentils in your soup, you'll probably see some with the radicles still attached.

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 color lentils are best for soup? ›

I recommend using green or French green lentils because they hold their shape in the soup, adding satisfying texture. Brown lentils are also a fine option.

What can you add to lentils to make them taste better? ›

You can also add salt, aromatics like a halved onion, herbs, and spices to the pot before the lentils and the water, like beans, or wait until they're done cooking to flavor them.

Does it matter what color lentils you use? ›

While brown lentils are fairly 'all-purpose,' red/yellow lentils are best for soups and stews where their mushy texture works well. In comparison, green and brown lentils maintain their shape after cooking and are great for salads, casseroles, side dishes, etc.

What happens if you don't cook lentils? ›

Lentils should always be consumed well-cooked as when raw or undercooked they can cause serious health problems, food poisoning and, in very extreme cases, even death. It's all because they contain natural compounds called lectins which are toxic but fortunately, cooking destroys them!

Do I need to pre cook lentils? ›

Nope! Unlike lots of other dried pulses (such as some dried beans), lentils don't need to be soaked before cooking. This means they're really quick and easy to use – you can decide you want to cook lentils when you're already ready to start cooking, and they can be ready to eat not long after.

Do I need to soak lentils before cooking them? ›

Lentils to do not require soaking like other pulses. Rinse your lentils with fresh water before boiling to remove any dust or debris. Cook on a stovetop, using 3 cups of liquid (water, stock, etc) to 1 cup of dry lentils. Be sure to use a large enough saucepan as the lentils will double or triple in size.

What happens if you don't cook lentils all the way? ›

In addition, undercooked lentils stay with lectin, an ingredient that may cause stomach problems like diarrhea or even food poisoning.
