Low-Glycemic Chicken and White Bean Casserole
A hearty, blood sugar-friendly chicken casserole packed with fiber-rich beans and vegetables that keeps you satisfied without the glucose spike.
This nourishing chicken casserole is specifically designed to support stable blood sugar levels while delivering maximum flavor and satisfaction. The combination of lean chicken thighs, fiber-rich haricot beans, and aromatic vegetables creates a complete meal that digests slowly, preventing rapid glucose spikes.
The secret to this recipe's glycemic benefits lies in its high fiber content from the white beans and vegetables, which slow down carbohydrate absorption. Chicken thighs provide quality protein and healthy fats that further moderate blood sugar response. The mirepoix base of onions, carrots, and celery adds natural sweetness without refined sugars, while fresh herbs enhance flavor without adding calories or carbs.
For optimal blood sugar management, eat the vegetables and protein first before any bread accompaniment. This casserole freezes beautifully, making it perfect for meal prep. Each serving provides approximately 25g of protein and 12g of fiber, creating a balanced macronutrient profile that promotes sustained energy and satiety for 4-5 hours.
Blood Sugar Impact
This meal will have a minimal to moderate impact on blood sugar with a slow, steady rise due to the low GI of 28 and moderate GL of 16.2. The combination of protein from chicken, fiber from beans and vegetables, and healthy fats will promote stable energy for 3-4 hours without significant spikes.
Blood Sugar Tips
- ✓ Eat the vegetables and chicken first before the beans to further slow carbohydrate absorption and minimize any blood sugar rise
- ✓ Pair this meal with a 10-15 minute walk after eating to help muscles absorb glucose and keep blood sugar stable
- ✓ Add a side of leafy greens or a small salad with vinegar-based dressing before the casserole to increase fiber and acetic acid, both of which blunt glucose response
🥗 Ingredients
- 2 tbsp sunflower oil
- 400 g boneless, skinless chicken thighs, trimmed and cut into chunks
- 1 pcs onion, finely chopped
- 3 pcs carrots, finely chopped
- 3 pcs celery stalks, finely chopped
- 2 pcs fresh thyme sprigs or 1/2 tsp dried thyme
- 1 pcs bay leaf, fresh or dried
- 600 ml vegetable or chicken stock, low-sodium preferred
- 800 g canned haricot beans, drained and rinsed
- 3 tbsp fresh parsley, chopped
- 2 tbsp sunflower oil
- 14.1 oz boneless, skinless chicken thighs, trimmed and cut into chunks
- 1 pcs onion, finely chopped
- 3 pcs carrots, finely chopped
- 3 pcs celery stalks, finely chopped
- 2 pcs fresh thyme sprigs or 1/2 tsp dried thyme
- 1 pcs bay leaf, fresh or dried
- 2.5 cups vegetable or chicken stock, low-sodium preferred
- 1.8 lb canned haricot beans, drained and rinsed
- 3 tbsp fresh parsley, chopped
👨🍳 Instructions
- 1
Heat the sunflower oil in a large, heavy-bottomed casserole pot or Dutch oven over medium-high heat until shimmering but not smoking.
- 2
Add the chicken thigh chunks in a single layer and cook undisturbed for 3-4 minutes until golden brown on the bottom. Turn pieces and brown on the other side, about 3 minutes more. The chicken doesn't need to be cooked through at this stage.
- 3
Add the finely chopped onion, carrots, and celery to the pot with the chicken. Reduce heat to medium and cook for 5-6 minutes, stirring occasionally, until the vegetables begin to soften and the onions become translucent.
- 4
Tuck the thyme sprigs and bay leaf into the vegetable mixture, then pour in the stock. Stir well to combine all ingredients and scrape up any browned bits from the bottom of the pot for extra flavor.
- 5
Bring the mixture to a rolling boil, then immediately reduce heat to low. Cover the pot with a tight-fitting lid and simmer gently for 40 minutes, stirring occasionally, until the chicken is completely tender and cooked through.
- 6
Add the drained haricot beans to the casserole and stir gently to distribute evenly. Continue simmering uncovered for 5-7 minutes to heat the beans through and allow the sauce to thicken slightly.
- 7
Remove from heat and discard the thyme sprigs and bay leaf. Taste and adjust seasoning with salt and black pepper if needed.
- 8
Sprinkle generously with freshly chopped parsley before serving. For best blood sugar control, serve with a small portion of whole grain bread or enjoy on its own as a complete meal. The casserole can be cooled and frozen in portions for up to 3 months.

🔄 Lower GI Swaps
These beans have significantly lower glycemic index (black soybeans GI ~15, lupini beans GI ~15) compared to haricot beans (GI ~30-35), resulting in much gentler blood sugar response while maintaining protein and fiber content.
Carrots have a moderate GI of 35-40 and higher sugar content. Zucchini, green beans, and cauliflower have GI values under 15 and minimal impact on blood glucose, reducing the overall glycemic load of the dish.
While both are low-GI proteins, chicken breast has virtually zero fat compared to thighs, which slows digestion less. However, the fat in thighs can actually help moderate blood sugar spikes from other ingredients, so this swap is optional for those prioritizing leanness over satiety.
These oils are richer in monounsaturated fats and have been shown in studies to improve insulin sensitivity and post-meal blood sugar control better than polyunsaturated sunflower oil, while adding no glycemic load.
🔬 The Science Behind This Recipe
Why This Recipe Works for Blood Sugar Balance
This chicken and white bean casserole is a masterclass in glycemic control, with a remarkably low glycemic index of 28 and a moderate glycemic load of 16.2 per serving. The secret lies in how these ingredients work together to slow glucose absorption. White beans are the star player here—they're packed with soluble fiber and resistant starch that literally slow down digestion in your intestines. When you eat beans, their fiber forms a gel-like substance that prevents rapid sugar absorption, leading to a gentle, sustained rise in blood glucose rather than a sharp spike. The chicken thighs add substantial protein and healthy fats, which further delay stomach emptying and create an even more gradual release of energy into your bloodstream.
The supporting vegetables—onions, carrots, and celery—contribute additional fiber and volume without adding significant carbohydrates. This combination creates what nutritionists call a "low glycemic load meal," meaning the total amount of carbohydrate that will impact your blood sugar is modest, even though you're eating a satisfying portion. The sunflower oil provides monounsaturated fats that help with nutrient absorption and add to the meal's staying power.
To maximize the blood sugar benefits of this dish, try eating your vegetables first, followed by the protein, and save any additional starches for last. A 10-15 minute walk after eating can help your muscles absorb glucose more efficiently, further blunting any blood sugar rise. This casserole is proof that blood sugar-friendly eating doesn't mean deprivation—it means choosing foods that work with your metabolism, not against it.
