3. Add broth and seasonings: Pour in chicken broth. Drop in the bay leaf and Parmesan rind if using. Bring to a gentle simmer.
4. Cook the chicken: Add the chicken pieces. Simmer 12–15 minutes for breasts or 18–20 minutes for thighs, until cooked through. Avoid a rolling boil to keep the meat tender.
5. Shred the chicken: Remove the chicken to a board. Shred with two forks into bite-size pieces. Return it to the pot.
6. Add zucchini: Stir in the sliced zucchini. Simmer 5–7 minutes until just tender but not mushy.

9. Serve: Ladle into bowls. Top with extra herbs and a grind of black pepper. A squeeze of lemon at the table is a nice touch.

Keeping It Fresh

Cool the soup to room temperature, then store it in airtight containers. It keeps in the fridge for up to 4 days.

The zucchini will soften slightly over time, but the flavor stays great.

For freezing, skip the cream and fresh herbs until reheating. Freeze in portions for up to 3 months. Thaw overnight in the fridge, reheat gently, then add a splash of cream and fresh herbs right before serving.

Health Benefits

• High protein: Chicken provides complete protein to support muscle and satiety.
• Low-carb and keto-friendly: Zucchini is naturally low in carbs and calories.
• Electrolyte-friendly: Using broth helps with sodium intake, which can be helpful on keto.
• Anti-inflammatory notes: Garlic, herbs, and turmeric add phytonutrients and antioxidants.
• Hydrating: A broth-based soup supports hydration while still feeling hearty.

Pitfalls to Watch Out For

• Overcooking the chicken: Boiling hard can make it tough. Keep the simmer gentle.
• Mushy zucchini: Add it near the end and check for tender-crisp texture.
• Hidden sugars in broth: Choose unsweetened, low-sodium broth to control flavor and carbs.
• Too acidic: Lemon is great, but add gradually and taste. Balance with a little cream or butter if it’s too sharp.
• Under-seasoning: Low-sodium broth needs extra salt. Taste often and adjust.

Alternatives

• Protein swaps: Use rotisserie chicken for speed, or turkey for a leaner option.For pescatarian, try cooked, flaked white fish added at the very end.
• Vegetable variations: Add spinach, kale, or sliced mushrooms in the last few minutes. Cauliflower florets also work well and keep carbs low.
• Herb profiles: Swap dill for thyme or rosemary for a cozier, savory vibe. Cilantro and a squeeze of lime create a brighter, almost tortilla-soup note (skip the tortillas, of course).
• Creamy vs. brothy: Keep it clear and light, or stir in cream or mascarpone for a velvety finish.
• Spice it up: Add a pinch of smoked paprika, cumin, or a splash of hot sauce for heat and depth.

FAQs

Q1. How many carbs are in this soup?

Exact carbs vary by brand of broth and cream, but a typical bowl (about 1.5 cups) with chicken, zucchini, and no cream lands around 4–6 net carbs.

Adding cream may add 1–2 more, depending on the amount.

Q2. Can I make it in a slow cooker?

Yes. Add everything except zucchini, herbs, lemon, and cream. Cook on Low for 4–6 hours.

Shred the chicken, add zucchini for the last 30–40 minutes, then finish with lemon, herbs, and cream if using.

Q3. What about an Instant Pot version?

Use Sauté for the aromatics. Add broth, chicken, bay leaf, and spices. Cook on High Pressure for 8 minutes (breasts) or 10 minutes (thighs), quick release, shred chicken, switch to Sauté, and simmer zucchini 3–5 minutes. Finish with lemon, herbs, and cream.

Q4. Can I use yellow squash instead of zucchini?

Absolutely. Yellow squash cooks and tastes similar, though it may soften a bit faster. Add it near the end and watch the texture.

Q5. How do I make it dairy-free?

Use olive or avocado oil and skip the butter and heavy cream. If you want creaminess, stir in a little unsweetened coconut cream at the end.

Q6. What if my broth tastes weak?

Simmer a bit longer to reduce and concentrate flavor. Add salt in small pinches, a splash of lemon for brightness, or a Parmesan rind while simmering for depth.

Q7. Can I add noodles and still keep it low-carb?

You can use zucchini noodles or shirataki noodles. Add them at the end just to warm through so they don’t get soggy.

Q8. Is this good for meal prep?

Very. Portion into containers and refrigerate up to 4 days. Add fresh herbs and lemon right before eating to keep flavors lively.
