Looking for an easy, healthy option to meal prep? This low-calorie weight loss soup is flavorful, satisfying, and ideal for eating throughout the week.
This is a simple, low-calorie veggie soup that works well for busy schedules. While I’m not a nutritionist, I love how easy this recipe is to prepare and reheat. It slow-cooks for about eight hours, so it’s great to set in the morning and come home to a hearty, healthy meal. Below you’ll find ingredient highlights, variations, and tips to keep it interesting through the week.
Key Ingredients
This soup is made from scratch using fresh vegetables and pantry staples. The full ingredient list and amounts are included in the recipe card below.
The base of this Slow Cooker Weight Loss Soup is simple: celery, carrots, leeks, green beans, cabbage, garlic, and Italian diced tomatoes simmered in chicken broth. Zucchini is added near the end so it stays tender instead of turning mushy. You can easily adapt this for Weight Watchers or other low-calorie plans by adjusting portion sizes and ingredients.
Variations
Make this soup your own with a few simple swaps:
- Use vegetable broth instead of chicken broth for a vegetarian version, though chicken broth adds extra depth of flavor.
- Swap or add vegetables like spinach, kale, bell peppers, mushrooms, cauliflower, broccoli, or diced sweet potatoes.
- For added protein, cook chicken breasts, ground turkey, or ground beef in the slow cooker from the start. Canned or cooked beans (such as cannellini) are a great plant-based option.
- Frozen vegetables work well if fresh aren’t available.
- Note: this recipe fills a full slow-cooker pot, so large additional volumes may require a larger cooker.
How to make Weight Loss Soup
Step One: Add the leeks, celery, green beans, carrots, garlic, and canned diced tomatoes to the slow cooker.
Step Two: Add the chopped cabbage and the seasonings, then pour in the chicken broth and give everything a stir.
Step Three: Cover and cook on LOW for 8 hours. When the cooking time is up, add thinly sliced zucchini.
Step Four: Cook an additional 30 minutes on HIGH, then stir and serve.
