Simple Steps to Make Slow Cooker Lentils
Add the lentils, chopped vegetables, tomatoes, and vegetable stock to the slow cooker, stirring to combine. Set to high and cook for about 3 ½ hours, or until the lentils are tender. Stir in the grated cheddar cheese, allowing it to melt completely before serving. Adjust seasoning as needed, then enjoy warm with your favorite side.
Tips for the Best Slow Cooker Lentils
For extra depth of flavor, sauté the mushrooms and bell peppers before adding them to the slow cooker. If you prefer a slightly spicier kick, toss in some red pepper flakes or smoked paprika. You can also swap cheddar for a sharper cheese like Gruyère for a bolder taste.
Storing and Reheating Leftovers
Store leftover lentils in an airtight container in the fridge for up to four days. Reheat gently on the stove with a splash of water or vegetable stock to loosen the texture. For longer storage, freeze in portioned containers for up to three months and thaw overnight in the fridge before reheating.
