Lentil soup is a staple in many cuisines around the world, and for good reason. It’s a nutritious, filling, and delicious meal that’s perfect for a weeknight dinner or a special occasion. And when made in a slow cooker, it’s incredibly easy to prepare and cook. In this article, we’ll take you through the process of making lentil soup in a slow cooker, from preparation to serving.
Why Make Lentil Soup in a Slow Cooker?
There are many reasons why making lentil soup in a slow cooker is a great idea. Here are a few:
- Convenience: Slow cookers are designed to make cooking easy and convenient. Simply add all the ingredients to the slow cooker, turn it on, and let it do the work for you.
- Time-saving: Slow cookers are perfect for busy people who don’t have a lot of time to spend in the kitchen. You can prepare the ingredients in the morning, add them to the slow cooker, and come home to a delicious, ready-to-eat meal.
- Nutrient retention: Slow cooking is a great way to retain the nutrients in your ingredients. Unlike high-heat cooking methods, slow cooking helps to preserve the vitamins and minerals in your food.
- Flavor development: Slow cooking allows the flavors in your ingredients to meld together and develop a rich, depth of flavor that’s hard to achieve with other cooking methods.
Choosing the Right Lentils
There are many types of lentils to choose from, each with its own unique texture and flavor. Here are a few popular varieties:
- Green lentils: These are the most commonly available type of lentil and are great for making soups and stews. They hold their shape well and have a mild flavor.
- Brown lentils: These lentils are similar to green lentils but have a slightly stronger flavor. They’re also great for making soups and stews.
- Red lentils: These lentils are smaller than green or brown lentils and have a more delicate flavor. They’re great for making soups and stews, but they can break down and become mushy if overcooked.
- Yellow lentils: These lentils are similar to red lentils but have a slightly stronger flavor. They’re great for making soups and stews, but they can also break down and become mushy if overcooked.
What to Look for When Buying Lentils
When buying lentils, there are a few things to look for to ensure you’re getting high-quality ingredients:
- Freshness: Look for lentils that are fresh and have not been sitting on the shelf for too long. Old lentils can be stale and may not cook properly.
- Moisture content: Lentils should be dry and free of moisture. If they’re too moist, they may not cook properly or may develop off-flavors.
- Debris: Look for lentils that are free of debris, such as stones or sticks. Debris can affect the texture and flavor of your soup.
Preparing the Ingredients
Before you start cooking, you’ll need to prepare the ingredients. Here’s what you’ll need:
- 1 cup dried lentils, rinsed and drained

Chopping the Vegetables
Chopping the vegetables is an important step in making lentil soup. Here are a few tips to keep in mind:
- Use a sharp knife: A sharp knife will make it easier to chop the vegetables and will help to prevent accidents.
- Chop the vegetables uniformly: Try to chop the vegetables into uniform pieces so that they cook evenly.
- Don’t over-chop: Don’t over-chop the vegetables, as this can make them too soft and mushy.
Cooking the Lentil Soup
Now that you’ve prepared the ingredients, it’s time to cook the lentil soup. Here’s what you need to do:

What are the benefits of using a slow cooker to make lentil soup?
Using a slow cooker to make lentil soup offers several benefits. Firstly, it allows for hands-off cooking, which means you can simply add all the ingredients to the slow cooker and let it do the work for you. This is especially convenient for busy people who don’t have a lot of time to spend in the kitchen. Additionally, slow cookers are great for cooking tougher ingredients like lentils, as they break down slowly over time, resulting in a tender and flavorful soup.
Another benefit of using a slow cooker is that it helps to extract all the flavors from the ingredients. As the soup cooks slowly, the flavors meld together, creating a rich and savory broth. This is especially true for lentil soup, which can be quite bland if not cooked properly. By using a slow cooker, you can ensure that your lentil soup is full of flavor and aroma.
What type of lentils is best for making lentil soup?
The type of lentils to use for making lentil soup depends on personal preference and the desired texture. Green or brown lentils are a good choice for lentil soup, as they hold their shape well and have a mild flavor. Red lentils, on the other hand, break down quickly and create a thicker, more porridge-like consistency. If you prefer a heartier soup, you can use a combination of green and red lentils.
It’s worth noting that some types of lentils, such as yellow or beluga lentils, have a stronger flavor and may not be suitable for lentil soup. If you’re new to cooking with lentils, it’s best to start with a mild variety like green or brown lentils. You can always experiment with different types of lentils once you gain more experience.
Can I add other ingredients to customize my lentil soup?
Yes, you can definitely add other ingredients to customize your lentil soup. Some popular additions include diced vegetables like carrots, celery, and onions, as well as spices like cumin, paprika, and thyme. You can also add some acidity, such as a squeeze of lemon juice or a splash of vinegar, to brighten up the flavors.
Other ingredients you might consider adding include diced tomatoes, spinach, or kale for added nutrition, or some heat, such as red pepper flakes or diced jalapenos, for an extra kick. Just be sure to adjust the cooking time and seasoning accordingly, as different ingredients can affect the overall flavor and texture of the soup.
How long does it take to cook lentil soup in a slow cooker?
The cooking time for lentil soup in a slow cooker can vary depending on the type of lentils used and the desired level of doneness. Generally, it takes around 6-8 hours on low or 3-4 hours on high to cook lentil soup in a slow cooker. However, if you’re using red lentils, which break down quickly, the cooking time may be shorter, around 4-6 hours on low or 2-3 hours on high.
It’s also worth noting that you can cook lentil soup on low overnight and wake up to a delicious, ready-to-eat meal. Just be sure to check the soup periodically to ensure that it’s not overcooking, as this can result in a mushy or unappetizing texture.
Can I make lentil soup in advance and freeze it?
Yes, you can definitely make lentil soup in advance and freeze it. In fact, lentil soup freezes very well and can be stored in the freezer for up to 3 months. To freeze, simply let the soup cool completely, then transfer it to an airtight container or freezer bag. When you’re ready to eat it, simply thaw the soup overnight in the fridge or reheat it in the slow cooker or on the stovetop.
It’s worth noting that frozen lentil soup may thicken slightly when reheated, so you may need to add a little water or broth to achieve the desired consistency. Additionally, if you’re planning to freeze the soup, it’s best to under-season it slightly, as the flavors may concentrate during the freezing process.
Is lentil soup a healthy option?
Yes, lentil soup is a very healthy option. Lentils are a type of legume that is high in protein, fiber, and nutrients like iron and potassium. They are also low in calories and fat, making them an excellent choice for those looking to lose weight or maintain a healthy diet. Additionally, lentil soup is often made with vegetables and spices, which add even more nutrients and antioxidants to the dish.
One of the biggest health benefits of lentil soup is its ability to lower cholesterol levels and improve heart health. The fiber and protein in lentils can help to slow down the digestion of fat and reduce the absorption of cholesterol, while the potassium content can help to lower blood pressure. Overall, lentil soup is a nutritious and delicious option for anyone looking to eat a healthier diet.
Can I serve lentil soup as a main course?
Yes, lentil soup can definitely be served as a main course. In fact, it’s a popular option for vegetarians and vegans, as it’s a filling and satisfying meal that’s packed with protein and nutrients. To make lentil soup more substantial, you can serve it with some crusty bread or over rice or noodles. You can also add some protein sources like diced chicken or tofu to make it more filling.
If you’re serving lentil soup as a main course, you may want to consider adding some extra ingredients to make it more substantial. Some options include diced vegetables like bell peppers or zucchini, or some heat, such as red pepper flakes or diced jalapenos. You can also serve the soup with a side of salad or roasted vegetables to round out the meal.
