Short summary: Slow-roasted tomato bisque can fit a diabetes-friendly meal when it is made without added sugar, kept moderate in sodium, and paired with protein or fiber. The main blood sugar issues are serving size, bread or crackers, and sweetened or highly processed tomato soup products.
Key takeaways
- Estimated per serving: about 120 calories, 4 g protein, 8 g net carbohydrate, and 6 g sugar from tomatoes and onion, depending on ingredients.
- Roasting tomatoes brings out sweetness without adding sugar.
- Choose low-sodium broth if blood pressure, kidney disease, or heart disease is a concern.
- If you have chronic kidney disease and need potassium guidance, tomato-based soups may need individual review.
Why this soup can work
Tomatoes, onion, garlic, olive oil, herbs, and broth make a simple soup that is lighter than many cream-based bisques. The CDC meal-planning approach focuses on the full meal rather than one ingredient. This soup works best when served with protein and nonstarchy vegetables, or with a measured carbohydrate side if that fits your plan.
The biggest upgrade over many packaged soups is control. You can limit sodium, skip added sugar, and choose the texture without relying on refined starch thickeners.
Recipe overview
- Prep time: 15 minutes
- Cook time: 45 minutes
- Servings: 6
- Estimated nutrition: about 120 calories, 4 g protein, 8 g net carbohydrate, and 6 g sugar per serving
Ingredients
- 2 lb Roma tomatoes, halved
- 1 medium onion, quartered
- 4 cloves garlic
- 3 tbsp olive oil
- 3 cups low-sodium vegetable broth
- 1/2 cup plain Greek yogurt or unsweetened plain dairy-free yogurt, optional
- 1 tsp dried basil or 2 tbsp fresh basil
- 1/2 tsp black pepper
- Salt to taste, used lightly
How to make it
- Heat oven to 400 F.
- Place tomatoes, onion, and garlic on a baking sheet. Toss with olive oil, pepper, basil, and a small amount of salt if using.
- Roast for about 35 to 40 minutes, until the tomatoes soften and edges begin to brown.
- Blend roasted vegetables with broth until smooth. Use caution with hot liquids and blend in batches if needed.
- Warm gently in a pot. Stir in plain yogurt off the heat if you want a creamier texture.
- Taste before adding more salt.
How to serve it
For a steadier meal, pair the soup with grilled chicken, fish, tofu, boiled eggs, beans, or a salad with protein. If you add crackers, bread, rice, or pasta, count that carbohydrate separately. Read labels carefully because tomato soups and broths can vary widely in sodium and added sugar.

Practical takeaway
Tomato bisque can be a smart soup choice when it is unsweetened, not too salty, and served as part of a balanced plate. If kidney disease affects your potassium plan, ask your care team how often tomato-based soups fit.
