Need a vegetarian slow-cooker soup recipe that will cook while you're at work? Try any of these easy vegetarian soups, packed with beans, lentils and colorful vegetables, for a comforting, hands-off meal.

These vegetarian slow-cooker soup recipes are built for busy days when you need something warm, reliable and hands-off. What starts as a few simple ingredients like beans, lentils and chopped vegetables becomes a comforting, flavorful and filling soup hours later when it’s time to lift the lid.

This collection includes easy vegetarian soups that are quick to prep and have a range of flavors and textures, from chunky to velvety-smooth. We selected these recipes because they’re hearty without being heavy and, of course, turn out perfectly when simmered in a slow cooker. Most use a combination of pantry-friendly ingredients and fresh vegetables, with some frozen ingredients, so you can start cooking without a special trip to the store.

Many recipes can be doubled and frozen for future meals or eaten throughout the week. Just be sure not to fill your cooker more than two-thirds full, one of our top slow cooker safety tips. These easy vegetarian soups are often a full meal in a bowl, but a vegetable side dish or crusty bread makes a great, easy accompaniment. So grab your slow cooker, gather your favorite veggies, and let’s get simmering.

Vegetarian Slow-Cooker Soup FAQ

What are the best vegetarian soups?

The best vegetarian soups are packed with flavor and hearty ingredients like lentils, beans and veggies, along with herbs and spices. Some of our favorite vegetarian soups include minestrone, potato leek, butternut squash and cheese tortellini soup. The recipes in this collection focus on long-simmering slow-cooker options, but you can also make soups that cook quickly (or not at all), like carrot ginger soup or gazpacho.

Are there vegetables that shouldn’t be added to a slow cooker?

You can add most vegetables to a slow cooker, but the timing of when you add them makes a difference. For example, if you add delicate vegetables such as zucchini, spinach or peas too early, they can become mushy or fall apart. Wait to add these until the last 15 to 30 minutes of cooking to ensure the best color and texture. In contrast, dense vegetables such as carrots and potatoes stand up well to long cook times and can go into the pot from the beginning. To ensure even cooking, cut tough vegetables, such as beets, carrots and potatoes into similar-sized pieces.

What are some other slow-cooker vegetarian recipes?

Since you already have your slow-cooker out, try some other great vegetarian slow-cooker recipes beyond soup, like vegetarian stuffed peppers or slow-cooker casseroles. These flavorful and filling dishes benefit from gently simmering in a slow cooker and gradually building layers of flavor without much attention or work. For easier cleanup, use a slow-cooker liner, especially with tomato-heavy or cheesy recipes.
