12 Diabetes-Friendly Soup Recipes: Low-Carb, High-Fiber and Easy

By Smith Lina, RD, CDCES · Medically reviewed by Dr. Emily Carter, MD, Board-Certified Endocrinologist · Last updated October 16, 2026

Soup can be one of the easiest ways to fit more vegetables into a day, and vegetables are the foundation of diabetes meal planning. The catch is that many canned and restaurant soups lean on starchy thickeners, added sugar and a lot of sodium. The twelve soups below are built differently: lots of non-starchy vegetables, a solid serving of protein, and carbohydrate foods kept to a measured portion.

Every recipe serves four, uses ordinary ingredients, and fits a weeknight. Pick the ones that suit your taste, and use the planning tips and food-safety notes after the recipes to make a batch last all week.

Quick answer: A diabetes-friendly soup is one where non-starchy vegetables make up most of the bowl, protein is included, and any beans, lentils, potatoes or pasta are counted as your carbohydrate portion. Check your own carb targets with your care team, because needs differ from person to person.

What makes a soup diabetes-friendly?

The American Diabetes Association’s Diabetes Plate Method gives a simple template: on a 9-inch plate, fill half with non-starchy vegetables, one quarter with protein, and one quarter with carbohydrate foods [1][2]. A bowl of soup can follow the same logic.

• Start with non-starchy vegetables. Broccoli, cauliflower, spinach, kale, zucchini, mushrooms, cabbage, tomatoes and onions add volume and fiber with little effect on blood glucose [2].
• Add protein. Chicken, turkey, fish, eggs, tofu and Greek yogurt keep the soup filling.
• Count your carbohydrates. The ADA lists beans, lentils and starchy vegetables such as potatoes, corn, peas and butternut squash as carbohydrate foods, so they need a measured portion rather than a free pour [2][3].
• Skip the hidden sugar and excess salt. Choose unsweetened bases, check the label on broth and canned tomatoes, and use herbs, citrus, garlic and spices for flavor.

Soups also pair well with the rest of the plate. For a fuller approach, see our diabetes meal plans and beginner guides.

The 12 soups

All recipes serve 4. Nutrition per serving is shown as a field to complete from your own calculation.

1. Lemon Chicken and Spinach Soup

Time: 30 minutes · Nutrition per serving: 210 calories / 6g net carbs / 3g fiber / 24g protein / 420mg sodium.

Ingredients: 1 tbsp olive oil, 1 diced onion, 2 diced celery stalks, 2 garlic cloves, 4 cups low-sodium chicken broth, 300 g (about 10 oz) boneless chicken breast, 4 cups fresh spinach, juice of 1 lemon, black pepper, dill.

Method: Soften the onion and celery in oil for 5 minutes, add garlic for 30 seconds, then pour in the broth and add the chicken. Simmer 15 minutes until cooked through, shred the chicken, return it to the pot and stir in spinach, lemon juice and dill until wilted.

Tip: No noodles or rice needed. The chicken keeps it satisfying.

2. Red Lentil and Carrot Soup

Time: 35 minutes · Nutrition per serving: 240 calories / 32g net carbs / 8g fiber / 11g protein / 380mg sodium.

Ingredients: 1 tbsp olive oil, 1 onion, 2 carrots, 3 garlic cloves, 1 tsp cumin, ½ tsp turmeric, ¾ cup (150 g) dry red lentils, 5 cups low-sodium vegetable broth, lemon wedges.

Method: Cook the onion and carrots in oil for 6 minutes, add garlic and spices for 1 minute, then add lentils and broth. Simmer 20 to 25 minutes until the lentils collapse, and blend part of the soup for a thicker texture.

Tip: Lentils are a carbohydrate food, so keep to a measured bowl and add a side of protein or a handful of greens. Compare your blood sugar after meals to see how it works for you.

3. Creamy Cauliflower Soup (No Cream)

Time: 30 minutes · Nutrition per serving: 180 calories / 12g net carbs / 5g fiber / 7g protein / 350mg sodium.

Ingredients: 1 head cauliflower in florets, 1 onion, 3 garlic cloves, 1 tbsp olive oil, 4 cups low-sodium broth, ½ cup unsweetened plain Greek yogurt or unsweetened milk, nutmeg, black pepper, chives.

Method: Sauté onion and garlic in oil, add cauliflower and broth, and simmer 15 minutes until tender. Blend until smooth, stir in the yogurt off the heat, and season.

Tip: Blended cauliflower gives the creaminess that potato or flour usually provides.

4. Kale and White Bean Soup

Time: 35 minutes · Nutrition per serving: 220 calories / 28g net carbs / 7g fiber / 12g protein / 340mg sodium.

Method: Brown the turkey in oil, add the onion and cook 4 minutes, then add vegetables, tomatoes, broth and herbs. Simmer 15 minutes, add the pasta if using, and cook until tender.

6. Egg Drop Soup with Mushrooms and Greens

Time: 15 minutes · Nutrition per serving: 140 calories / 4g net carbs / 2g fiber / 12g protein / 310mg sodium.

Method: Heat the water or broth with the mushrooms for 5 minutes. Add tofu and bok choy for 2 minutes, then turn off the heat and whisk in the miso. Do not boil after adding it.

Tip: Miso is salty, so taste before adding any other salt.

8. Roasted Tomato and Basil Soup

Method: Roast the vegetables with oil at 200°C (400°F) for 30 minutes until soft and browned at the edges. Blend with the broth and basil, and reheat gently.

How to build a balanced bowl

1. Pick a vegetable base from the non-starchy list in the ADA plate method [2].
2. Add a protein (about a quarter of the meal) [1].
3. Measure your carbohydrate food. Beans, lentils, pasta, potatoes and winter squash all count [2][3].
4. Flavor without sugar. Use onion, garlic, ginger, lemon, vinegar, herbs and spices.
5. Choose water or another zero-calorie drink to complete the plate [1].

About cinnamon, turmeric and “blood sugar-lowering” spices

You will see claims that certain spices lower blood sugar. The evidence is weaker than the headlines. A Cochrane review of randomized trials found insufficient evidence to support cinnamon as a treatment for type 1 or type 2 diabetes [4], and Mayo Clinic notes that results across studies are mixed [5]. A 2024 meta-analysis of 24 trials reported small improvements in fasting glucose and A1C with cinnamon supplements, while still describing the results as inconclusive overall [6]. Spices make soup taste good, so use them freely, but do not treat them as a substitute for medication or your care plan. If you take glucose-lowering medicine, ask your clinician before using supplements.

Storing and reheating soup safely

Batch cooking is one of soup’s biggest advantages, provided you handle leftovers safely. The USDA recommends the following [7][8]:

• Refrigerate or freeze leftovers within 2 hours of cooking.
• Divide large pots into small, shallow containers so they cool quickly.
• Keep refrigerated soup for 3 to 4 days, and use frozen soup within about 3 to 4 months for the best quality.
• Reheat soup to a rolling boil and make sure leftovers reach 165°F (74°C).

Yogurt-based cold soups (recipes 9 and 10) are best eaten within a day or two, and soups with egg or tofu are best fresh.
