The chicken breast is your protein anchor here—boneless, skinless cuts keep calories in check while delivering that satisfying fullness. Costco or Trader Joe's usually have pre-cut options, but if you're buying whole breasts, trim any visible fat. For the broth, homemade is ideal but a quality low-sodium brand like Pacific Foods works in a pinch. The veggies? Organic produce has fewer pesticides, but conventional works too if you're washing thoroughly. Look for firm zucchini and bright orange carrots—they'll hold up better during cooking.
No fresh parsley? Fresh cilantro or basil work just as well for garnish. Short on spinach? Kale or Swiss chard add similar nutrition. The tomatoes can be fresh if you prefer—just chop them yourself. For extra flavor without calories, add a splash of balsamic vinegar at the end. Want to boost protein further? Add 1 cup cooked quinoa or ½ cup lentils to the finished soup. The herbs? Penzeys or bulk bins have the freshest dried options—look for vibrant color and no strong off smells.
This soup reheats beautifully—just add a splash of broth or water if it gets too thick. Stores for 5 days in the fridge or 3 months frozen. I always make a double batch and portion it into containers for easy grab-and-go meals. For the 17-day plan, prep the whole recipe at once—it's perfect for meal prep. The flavors actually improve after the first day as everything melds together. Leftovers? Freeze in single-serving portions for quick lunches.

Step-by-step instructions for low-calorie, high-protein cleansing bowl
Here's how to create a nutrient-packed, cleansing soup that balances protein and vegetables perfectly.
Sear the Chicken for Maximum Flavor
Heat a large pot over medium-high heat with 1 tablespoon olive oil (not listed but essential for searing). Add the 1.5 lb lean chicken breast cut into bite-sized pieces and cook for 5-6 minutes until the edges turn light golden brown and the chicken is no longer pink in the center. This quick sear locks in moisture while building deep flavor.
I like to work in batches if needed to avoid overcrowding the pan—this ensures each piece gets proper browning instead of steaming. Once fully cooked, remove the chicken with a slotted spoon and set aside. You'll add it back later, but first, we're building that rich vegetable base.
Sauté the Vegetable Base
In the same pot, reduce heat to medium and add 1 tablespoon more olive oil. Toss in the diced onion and minced garlic cloves, cooking for 3-4 minutes until the onion becomes translucent and the garlic releases its aromatic punch. This is where the foundation of your soup's flavor develops.
Next, add the diced red bell pepper, chopped celery stalks, and peeled and sliced carrots. Stir well and cook for another 5 minutes until the vegetables begin to soften but still retain a slight crispness. The 1 lb zucchini sliced into half-moons goes in last, cooking for just 2 minutes to preserve its texture and vibrant color.
Build the Broth and Season
Pour in the 6 cups low-sodium chicken broth and the 1 can canned diced tomatoes (with juices). Bring everything to a gentle boil, then reduce heat to low-medium and let it simmer for 15 minutes. This allows the vegetables to fully tenderize while the broth absorbs their natural sweetness and depth.
Stir in the 1 tsp dried thyme, 1 tsp dried basil, 0.5 tsp black pepper, and 0.5 tsp sea salt, adjusting to taste. The herbs will infuse the broth with earthy notes, while the pepper adds a subtle warmth. Here's the thing—taste as you go. The broth should be seasoned but not overwhelming, as the vegetables will contribute their own flavors.
Finish with Spinach and Garnish
Just before serving, stir in the 4 cups fresh spinach and cook for 1-2 minutes until just wilted—this preserves its bright green color and crisp texture. The spinach should be vibrant, not mushy, so don't let it overcook. Return the seared chicken to the pot and let it warm through for 2-3 minutes.
Ladle the soup into bowls and garnish with the 0.25 cup fresh parsley. The parsley adds a fresh, bright finish that cuts through the richness of the chicken and vegetables. Serve immediately while hot, and enjoy the perfect balance of protein, fiber, and flavor in every spoonful.
Pro Tips For Making 17 Day Diet Soup
- SEAR CHICKEN FIRST: If you skip browning the chicken breast, your soup will taste like hospital food. Cut it into thin strips, pat them very dry with paper towels, and sear in a hot pan with a little oil—just 2-3 minutes per side until golden. The crust locks in flavor and keeps the meat from turning rubbery when simmered.
- CHOP ZUCCHINI SMALL: Big chunks of zucchini turn mushy in broth. Dice it into ½-inch pieces—small enough to soften but not disappear. I learned this the hard way when my first batch turned into a sad, watery vegetable sludge. (Yes, even if you’re impatient like me, resist the urge to go big.)
- ADD SPINACH LAST: Tossing spinach into boiling broth wilts it into oblivion. Instead, stir it in during the final 2 minutes of cooking—just until the leaves soften but still hold shape. This keeps the soup vibrant and prevents a sad, slimy texture that ruins the whole dish.
- SIMMER LOW AND LONG: Rushing the simmer? Your carrots will stay crunchy and the broth won’t meld. Keep the heat at a gentle bubble (not a rolling boil) for at least 20 minutes after adding all ingredients. This builds depth of flavor and ensures the chicken stays tender—no more dry, overcooked bites. (Your future self will thank you.)
Common mistakes when making perfect results
Overcooking Vegetables
I’ve seen this happen more times than I can count—veggies like zucchini and spinach turn to mush when simmered too long. The key is timing: add zucchini 2 minutes before serving and spinach just 1-2 minutes before the end. Overcooking strips away their vibrant color and crisp texture, making the soup feel bland. Keep an eye on the clock and taste-test as you go. 🌱
Skipping the Sear
If you skip searing the chicken, you’ll miss out on deep, caramelized flavor that makes this soup taste restaurant-quality. That 5-6 minute sear creates the Maillard reaction, which builds rich, savory notes. Use medium-high heat and work in batches if needed—crowding the pan steams instead of browns. Trust me, your taste buds will notice the difference. 🔥
Ignoring Broth Quality
Low-sodium broth is a must, but don’t cut corners here. Homemade broth has far superior flavor, but if you’re using store-bought, Pacific Foods or Swanson are solid choices. Avoid broths with added MSG or preservatives—they can make your soup taste artificial. For extra depth, add 1 tsp tomato paste to the broth while simmering. It’s a game-changer for flavor without calories. 💧
Underseasoning
Many diet soups end up tasting flat because people fear added salt or spices. But this soup needs bold, balanced seasoning—start with the herbs and spices as written, then adjust. Taste the broth before adding chicken and again at the end. A pinch of red pepper flakes or a squeeze of lemon juice can brighten flavors without calories. Don’t be afraid to season—it’s what makes diet food taste satisfying. 🌶️
Not Prepping Ahead
This soup is perfect for meal prep, but I’ve seen people waste time chopping veggies fresh each day. Prep everything the night before: chop onions, garlic, bell peppers, and carrots, and store in airtight containers in the fridge. Even better, make the entire soup ahead—it tastes even better the next day as flavors meld. Portion into single-serving containers for grab-and-go meals during your 17-day cleanse. ⏰
Using Wrong Chicken
Not all chicken breast is created equal. Skinless, boneless cuts are essential for keeping calories low, but lean doesn’t mean flavorless. Look for plump, firm pieces—avoid thin or dry cuts that can turn rubbery. If your chicken tastes bland, marinate it for 15 minutes in 1 tbsp olive oil, 1 tsp lemon juice, and ½ tsp garlic powder before searing. This adds moisture and flavor without extra calories. 🍗
Nutrition facts
Frequently asked questions
Can I make this soup vegetarian or vegan?
Replace the chicken with 1.5 cups cooked lentils or 1 block firm tofu (pressed and cubed) for protein. Use vegetable broth instead of chicken broth, and add 1 tsp smoked paprika for depth. For vegan, ensure all ingredients (like broth) are plant-based. The flavor profile stays rich and satisfying.
How do I adjust portions for the 17-day diet?
This recipe makes 6 servings, perfect for 3 days of meals. For the full 17-day plan, double the recipe and store in airtight containers. Portion into single-serving containers (about 1.5 cups per serving) to grab-and-go. Pair with 1 slice whole-grain bread or a side salad for added nutrients.
Can I freeze this soup for later?
Yes! Freeze in single-serving portions for up to 3 months. Let it thaw overnight in the fridge, then reheat on low heat with a splash of broth to restore texture. Avoid microwaving directly from frozen—it can make the soup watery. Stir well before serving to redistribute flavors.
What if I don’t have fresh herbs?
No problem! Use ½ tsp dried oregano instead of fresh parsley for garnish, or swap basil/thyme with ½ tsp dried Italian seasoning. For extra flavor, add 1 tsp lemon zest or a dash of hot sauce (check for low-sodium options). The soup will still taste delicious without fresh herbs.
Is this soup safe for people with high blood pressure?
Yes, this recipe is designed to be low-sodium! We use low-sodium broth and minimal added salt. For extra safety, skip the salt entirely and rely on herbs and spices for flavor. The natural umami from tomatoes and mushrooms (if added) will enhance taste without sodium.
