low cal high protein soup
There’s a common misconception that a soup meant for nourishment has to be bland or brothy. As a chef, I’ve spent years proving otherwise. This Lemon Chicken & White Bean Soup is my go-to when I need a meal that feels like a warm hug but fuels my body like premium fuel.
It’s the perfect answer to that post-workout hunger or a busy weeknight when you want something wholesome on the table fast. You get tender, seared chicken, creamy beans, and a broth that’s somehow both light and deeply savory, all brightened with a hit of fresh lemon. It’s a bowl that satisfies every craving without any guilt.
- Protein-Packed & Satisfying: With 35 grams of protein per serving, this soup is a complete meal that will keep you full for hours, making it ideal for fitness goals or managing hunger.
- One-Pot Convenience: Minimal cleanup is a major win. Everything cooks in a single pot, from searing the chicken to simmering the broth.
- Big Flavor, Low Calories: We build layers of flavor by searing the chicken and sautéing aromatics, resulting in a rich-tasting soup that’s surprisingly low in calories.
- Meal Prep Champion: This soup tastes even better the next day and stores beautifully in the fridge or freezer for effortless healthy lunches all week.
- Diet-Flexible: Naturally gluten-free and dairy-free, it’s easy to adapt for various dietary needs without sacrificing taste or texture.
- Quick & Approachable: From chopping to serving, you’re only about 45 minutes away from a restaurant-quality, healthy soup made in your own kitchen.
Ingredients You’ll Need
Let’s gather our ingredients—this is where simple, wholesome components come together to create something truly special. You’ll notice there’s no cream or butter; the richness comes from technique and the natural creaminess of the beans.
- Chicken Breasts: I recommend boneless, skinless breasts for their lean protein. Cutting them into uniform cubes ensures quick, even cooking.
- Olive Oil: Just a tablespoon divided for cooking. It’s our healthy fat that carries flavor and helps achieve a beautiful sear.
- The Aromatics: A classic mirepoix of onion, celery, and carrots forms the flavorful base. Garlic adds its essential savory note.
- Chicken Broth: Use a good-quality, low-sodium broth. This lets you control the final salt level and ensures the lemon flavor shines through.
- Cannellini Beans: These white beans are mild, creamy, and packed with fiber and plant-based protein. Rinsing them removes excess sodium from the canning liquid.
- Seasonings: Dried oregano and a bay leaf provide an herby backbone. Fresh lemon (both zest and juice) is the non-negotiable bright finish.
- Fresh Spinach: Stirred in at the end, it wilts perfectly and adds a pop of color and nutrients without extra cooking.
- Fresh Parsley: For garnish. It adds a fresh, clean note that complements the lemon beautifully.
Trust me, using fresh lemon juice and zest instead of bottled makes a world of difference in the final, vibrant flavor.

Kitchen Equipment Needed
You don’t need any fancy gadgets for this recipe. A large Dutch oven or heavy-bottomed soup pot (around 5-6 quarts) is essential for even heat distribution and preventing burns. A sharp chef’s knife and cutting board will make prepping the vegetables and chicken a breeze.
A wooden spoon is perfect for stirring and scraping up the flavorful browned bits (the fond) from the pot. Finally, a microplane or fine zester will get you the perfect fluffy lemon zest without the bitter white pith. That’s really it!
How to Make Hearty Lemon Chicken & White Bean Soup Recipe
Step 1: Sear the Chicken
In your large pot, heat a teaspoon of oil over medium-high heat. Pat your cubed chicken dry and season it well—this helps it brown instead of steam. Add the chicken in a single layer.
Believe me, crowding the pan is the enemy of a good sear. Let it sit undisturbed for a few minutes to develop a golden-brown crust before turning. This Maillard reaction isn’t just for looks; it creates complex, savory flavor compounds that will infuse your entire soup.
Remove the chicken to a plate once seared.
Step 2: Build the Flavor Base
There’s no need to wash the pot—those browned bits are flavor gold! Add the remaining oil and reduce the heat to medium. Add your diced onion, celery, and carrots.
We’re going to sweat them here, not brown them, so cook until they’re softened and fragrant, about 7-8 minutes. Tip from me: a pinch of salt at this stage helps draw out their moisture and speeds up the process. Stir in the garlic for just one last minute until you smell its irresistible aroma.
Step 3: Deglaze and Simmer
Now for the satisfying part: pour in all of your chicken broth. As you pour, use your wooden spoon to scrape up every last bit of browned goodness from the bottom of the pot. This is called deglazing, and it’s the secret to a deeply flavorful broth.
Add the seared chicken back in, along with the drained beans, oregano, and bay leaf. Bring everything to a lively boil.
Step 4: The Gentle Cook
Once boiling, immediately reduce the heat to low, cover the pot, and let it simmer gently. This slow, covered cooking allows the chicken to become incredibly tender and the flavors to marry perfectly. Set a timer for 15-18 minutes.
You’ll know it’s done when the chicken is cooked through (no pink inside) and the carrots are easily pierced with a fork.
Step 5: The Bright Finish and Serve
Remove the pot from the heat. Fish out and discard the bay leaf. Now, stir in the fresh spinach, lemon zest, and lemon juice.
The residual heat is perfect for wilting the spinach without overcooking it. Adding the lemon off the heat preserves its bright, floral notes. Taste—this is crucial.
Does it need another pinch of salt or a crack of pepper? Adjust now. Ladle the soup into deep bowls, garnish with fresh parsley, and step back to admire your beautiful, healthy creation.
- Chicken Texture Secret: For the most tender chicken, avoid a rolling boil during the simmering stage. A gentle simmer (small bubbles breaking the surface) is key.
- Don’t Skip the Sear: Searing the chicken isn’t just about color. It creates a flavor foundation that a soup made with boiled, raw chicken simply cannot match.
- Acid Timing: Always add acidic ingredients like lemon juice or vinegar at the end of cooking. Adding them too early can cause the proteins in the chicken and beans to toughen slightly and can mute the bright flavor.
- Bean Prep: Always rinse canned beans thoroughly in a colander. This removes the starchy, sometimes salty liquid they’re packed in, which can cloud your broth and throw off the seasoning.
- Broth Power: If your soup tastes a little flat at the end, it likely just needs salt. Season in layers: salt the chicken, salt the vegetables, and always do a final taste and adjust before serving.
Recipe Variations
- Herb Garden Version: Stir in ¼ cup of chopped fresh dill or tarragon along with the parsley at the end for a wonderfully aromatic twist.
- Spicy Kick: Add ½ teaspoon of red pepper flakes when you cook the garlic, or garnish each bowl with a drizzle of chili crisp for heat and crunch.
- Vegan/Vegetarian Adaptation: Omit the chicken. Use vegetable broth and add an extra can of beans or 1 cup of brown lentils with the broth. Increase the simmer time to 25 minutes for lentils.
- Greek-Inspired: Add 1 teaspoon of dried mint with the oregano and finish the soup with a sprinkle of crumbled feta cheese (note: adds dairy and calories).
- Keto/Lower-Carb: Simply reduce the amount of carrots and cannellini beans by half, and increase the chicken by ½ pound. The broth will still be flavorful and satisfying.
What to Serve With This Recipe
This soup is a complete meal in a bowl, but it pairs wonderfully with a simple side salad dressed with a light vinaigrette for a perfect lunch. For dinner, I love serving it with a slice of crusty, whole-grain bread or a few whole-wheat crackers for dipping and scooping. If you’re hosting, a platter of roasted asparagus or broccoli makes a beautiful and healthy companion on the table.
It’s an ideal meal for chilly evenings, post-workout recovery, or anytime you need a nourishing reset.
Storage & Make-Ahead Instructions
- Refrigerator: Cool the soup completely, then store in an airtight container for up to 4 days. The flavors meld and improve, making it fantastic for meal prep.
- Freezer: This soup freezes exceptionally well. Portion it into freezer-safe containers or bags, leaving an inch for expansion, and freeze for up to 3 months. Thaw overnight in the refrigerator.
- Reheating: Gently reheat on the stovetop over medium-low heat, stirring occasionally. If the soup has thickened in the fridge, add a splash of broth or water to loosen it.
- Make-Ahead: You can chop all vegetables and cube the chicken a day in advance. Store them separately in sealed containers in the fridge to cut your active prep time in half.
Frequently Asked Questions
Q: Can I use chicken thighs instead of breasts?
Absolutely. Boneless, skinless thighs will add more flavor and stay juicier, but they also contain more fat, which will increase the calorie count slightly. The cooking time remains the same.
Q: My soup is too thin. How can I thicken it?
Remove about 1 cup of the soup (mostly beans and vegetables), blend it until smooth using an immersion blender or regular blender, and stir it back into the pot. This creates a naturally creamy, thicker broth without any flour or cornstarch.
Q: Can I make this in a slow cooker or Instant Pot?
Yes. For a slow cooker: sear chicken on the stove, then add everything except spinach and lemon to the pot. Cook on LOW for 6-7 hours or HIGH for 3-4.
Stir in spinach and lemon at the end. For Instant Pot: use the Sauté function for Steps 1 & 2, then add broth, beans, and seasonings (not lemon/spinach). Pressure cook on High for 8 minutes, quick release, then stir in lemon and spinach.
Q: Are there other greens I can use besides spinach?
Chopped kale or Swiss chard are excellent, heartier alternatives. Add them in the last 5 minutes of simmering so they have time to soften properly.
Q: Why did my lemon juice make the chicken taste tough?
This happens if the lemon juice is added while the soup is at a hard boil. Always remove the pot from the heat before stirring in the acid to prevent the proteins from seizing.
Q: Is this soup suitable for freezing?
It freezes beautifully. The beans and chicken hold their texture well. Just remember to cool it completely before freezing and leave headspace in your container.
Q: How can I increase the protein even more?
Stir in ½ cup of cooked quinoa or farro with the beans, or add an extra ½ pound of chicken breast. You could also garnish each bowl with a tablespoon of nutritional yeast for a cheesy, protein-boosted flavor.

Method
- In a large Dutch oven or heavy-bottomed pot, heat 1 teaspoon of olive oil over medium-high heat. Season the cubed chicken with salt and pepper. Add chicken to the pot in a single layer (work in batches if needed) and sear until golden brown on all sides, about 5-6 minutes total. Remove chicken to a plate and set aside. This step builds flavor through the Maillard reaction—don’t skip it!
- Reduce heat to medium and add the remaining olive oil to the same pot. Add the diced onion, celery, and carrots. Cook, stirring occasionally, until the vegetables have softened and the onion is translucent, about 7-8 minutes. Add the minced garlic and cook for 1 more minute until fragrant.
- Pour in the chicken broth, using a wooden spoon to scrape up any browned bits from the bottom of the pot—that’s pure flavor. Add the seared chicken back to the pot, along with the rinsed cannellini beans, dried oregano, and bay leaf. Bring the soup to a boil.
- Once boiling, reduce the heat to maintain a gentle simmer. Cover the pot and let it cook for 15-18 minutes, or until the chicken is cooked through and tender and the vegetables are soft.
- Remove the pot from the heat. Discard the bay leaf. Stir in the fresh spinach, lemon zest, and lemon juice. The residual heat will perfectly wilt the spinach. Taste the soup and adjust seasoning with more salt and pepper as needed. Ladle into bowls and garnish with fresh parsley.
