15 Healthy Slow Cooker Soups, all Under 300 Calories

Have you ever wanted to try making slow cooker soups but don’t know where to begin? We’ve got your back! There are tons of different recipes out there. From gourmet-style cooking with fresh ingredients to prepackaged convenience foods, the possibilities are endless.
We searched for low-calorie slow cooker soup recipes that use everyday household items you can find at your local grocery store. That’s right – nothing too strange or exotic here. Just wholesome ingredients combined in a way that will leave you wanting more. After all, it is easy enough to doctor up the taste using condiments or other spices later on if that’s what floats your boat! Check it all out below:

1. Slow Cooker Vegetable Soup

The meal you see here is simple; you might even feel guilty for calling it a recipe. And honestly, no one will fault you for that since there are only 4 ingredients!
The best part of this recipe is how easy it is to customize it to meet your family’s needs or dietary restrictions. You can easily change the vegetables used and incorporate whatever canned goods your heart desires. If using canned veggies makes you nervous because of BPA concerns, go ahead and use fresh instead! It’ll just take more chopping on your part (or maybe some extra money spent at the grocery store if they’re not in season).

2. Slow Cooker Black Bean Soup

This vegan black bean soup recipe uses a handful of spices – oregano, cumin, chili powder, and cayenne pepper – to give it that slow-cooked signature taste.
Black beans are loaded with fiber, antioxidants, vitamins, minerals, and other nutrients, making them one of the top vegan foods you should incorporate into your diet! You can find these ingredients in any grocery store or online.

3. Slow Cooker Tomato Basil Parmesan Soup

This recipe takes only about 4 hours on high heat (or 6+ hours on low). But luckily, many of the most common slow cooker soups take even less time than that! The trick is to let the flavors blend just right without overcooking everything. Just perfect for someone who’s short on time but loves tasty food they didn’t have to slave over in the kitchen.
One of the most challenging parts of this recipe is shopping for all the right ingredients. Fresh tomatoes and basil? Kale? Parmesan cheese? If you can’t find any or don’t want to spend too much money on specialty items, go ahead and swap in unseasoned diced tomatoes, spinach, and grated cheddar instead! It just might not taste quite as authentic without that rich Italian flavor, but it still tastes good.

4. Slow Cooker Vegetarian Chili

Worried about making a slow cooker chili recipe because it sounds complicated? Don’t be! It’s easier than you think to make a tasty vegetarian chili for dinner, even if you have zero cooking experience. All it takes is adding all of your favorite ingredients – beans, veggies, spices – to a large pot regardless of whether it’s a gas stove, electric stove, or slow cooker.
Just like with the vegetables for this hearty vegetable soup, be sure to pick out canned goods that do not contain BPA (Bisphenol A). You can find some suggestions here. And feel free to experiment with different spices and seasoning mixtures until you discover your favorite combination!

5. Slow Cooker Tomato Tortellini Soup

This hearty tomato tortellini soup is not only vegan-friendly but it’s also packed with protein! A whole slew of spices – oregano, chili powder, parsley, rosemary, thyme, garlic powder – are mixed into this sauce before cooking. They aren’t super visible, but they make a big difference in terms of flavor!
And finally, slow cooker meals don’t have to include meat. We’ve already mentioned how tasty vegetarian chili recipes are, but vegans shouldn’t feel left out either! You won’t even miss the meat in this tomato tortellini soup. A delicious vegan substitute is tofu, which you can add to your soup right before serving.
Remember that if you’re cooking for one or two people, a small 4-quart slow cooker is probably big enough. But if you’re feeding more than four people regularly, a larger 6- or 7-quart model will suit everyone’s needs better. Make sure the lid fits securely to prevent any spills while cooking, and watch out for cheaper models with glass lids – they heat up quickly and tend to break when taken off the stove.

6. Slow Cooker Thai Peanut Chicken Soup

This isn’t your average chicken noodle soup! It only takes about ten minutes to prep this recipe, but you’ll have to wait a few hours for your taste buds to thank you. If you want to make it a meal in one pot, add some precooked meat like rotisserie chicken or leftover steak tips. This will infuse the soup with flavor and save extra time when cooking.

7. Slow Cooker Creamy Tomato Basil Soup With Grilled Cheese Croutons

Homemade tomato basil soup is super tasty on its own, but if you want to take it up a notch, try these cheesy grilled cheese croutons. They’re crunchy on the outside and filled with warm gooey goodness inside!
You can also switch this recipe up by using different cheeses. Try topping off your soup with cheddar, Swiss, or feta. (Not into cheese? This soup tastes great without it too!)

8. Slow Cooker Cheesy Broccoli Soup

Cheesy broccoli soup with bacon? We know what you’re thinking: how could anything involving bacon not be good? But actually, there’s no need to worry about the salt content in this recipe since most of it comes from an entire package of shredded cheddar cheese. If that doesn’t convince you, think about how delicious broccoli cheese soup tastes without any bacon at all.
Add cooked rice to your cheesy broccoli soup for an extra filling meal. Or, if you want to switch things up, oat flour mixed with water can be used in place of the chicken or vegetable broth.

9. Slow Cooker Vegetable Soup With Quinoa And Cannellini Beans

This flavorful slow cooker recipe is so easy to follow! All you need are carrots, celery, onions, garlic, cannellini beans (or another type of white bean), quinoa, and low sodium vegetable or chicken broth. The cooking time will vary depending on if you’re using a traditional stovetop pot or a cooker, but either way, this soup will get everyone’s mouths watering at the end of the day. Add in some cut-up zucchini, sliced cabbage, or chopped spinach for even more nutrients.
Feel free to experiment with different vegetables and seasonings that suit your tastes best. Cooking soup is all about personalizing it! You can also switch out the cannellini beans for black beans or kidney beans if you prefer. (Not a fan of beans? Replace them with potatoes instead.)

10. Slow Cooker Butternut Squash And Pear Soup With Sage Bread Croutons

This butternut squash soup recipe is super easy to make – it’ll take less than 10 minutes of prep time before popping it into your slow cooker. The hardest part is waiting for it to finish cooking before you can dig in!

11. Slow Cooker Split Pea Soup With Ham

Ham isn’t just great with eggs; it also works well with this split pea soup. If you’re not into ham or want to keep things vegetarian, leave out the meat and make sure to add an extra 2 cups of vegetable broth instead. (Don’t worry, this soup will still taste delicious!) Just like all good slow cooker recipes, this one only takes about 10 minutes of prep time. You’ll need dried green split peas, minced garlic, salt & pepper, onion powder, diced carrots, chopped celery, cubed ham steaks, chicken broth, and water.
Saute your vegetables in a pan with olive oil first before placing them into the slow cooker. This will help release and distribute their flavors more evenly throughout the soup.

13. Slow Cooker Potato Soup

Potato soup is a classic for a reason – it’s so easy to make and packed full of nutritious ingredients. Just place diced potatoes, chopped onions, peeled garlic cloves, chicken broth, salt & pepper, and water into your slow cooker. After your meal is done cooking, blend everything until it turns into a smooth soup consistency. You can also use an immersion blender to do this step right in the slow cooker itself if you don’t mind getting your hands dirty! Top off each bowl with some shredded cheese, bits of bacon, or chives before serving.

14. Slow Cooker Cream Of Tomato Soup

Canned tomatoes give this cream of tomato soup its rich flavor and color. This recipe is so simple! Combine everything in your slow cooker and cook on low heat for 8 hours. If you’re not sure how long each of your workdays will be or don’t have 8 free hours to spend making dinner every night, try doubling up on this recipe instead. There won’t be any noticeable difference in the resulting flavor – the soup will taste just as delicious!

15. Slow Cooker Chicken Marsala Soup With Mushrooms & Spinach

This super easy slow cooker chicken marsala is packed with protein and vitamins! You can get it ready in just 10 minutes, making it the perfect choice when you’re looking for healthy recipes to serve at home or pack up for lunch. Serve on its own or pair this soup with some garlic breadsticks, Italian bread slices, or a simple green salad. Speaking of healthy, try this trick next time you make pasta dishes that require cheese: grate the Parmesan ahead of time, then freeze each block into ice cube trays. Not only will you save yourself some time, but it’ll melt just as quickly and evenly when you toss it into your hot entrees.

These foods are perfect for anything from weight loss diets to omnivore meals. They each have their unique flavor combinations, which will leave your taste buds satisfied! Many of them are inexpensive and easy to prepare – so no matter if you’re cooking for one person or an entire family, you’ll always have a healthy dinner at the end of the day. Stay happy and eat well!
