Ingredients Method

Ingredients

  

• 2 tablespoons olive oil (plus 1 teaspoon from the sun-dried tomato jar, optional)
• 1 medium yellow onion, finely diced
• 4 cloves garlic, minced
• 1 teaspoon dried Italian seasoning (or a mix of oregano, basil, and thyme)
• 1/2 teaspoon crushed red pepper flakes (optional, adjust to taste)
• 1/2 cup sun-dried tomatoes in oil, drained and sliced
• 1 large zucchini, diced small
• 6 cups low-sodium chicken broth
• 1 1/2 pounds cooked shredded chicken (rotisserie or leftover; see notes for raw)
• 3 cups baby spinach (or chopped kale, ribs removed)
• 3/4 cup heavy cream (or 1/2 cup heavy cream + 1/4 cup half-and-half)
• 1/2 cup freshly grated Parmesan cheese, plus extra for serving
• 1 tablespoon lemon juice (about 1/2 lemon), plus zest to taste
• Salt and black pepper, to taste
• Fresh basil or parsley, chopped, for garnish

Method

 

1. Sweat the aromatics: Warm olive oil in a large pot over medium heat. Add onion with a pinch of salt. Cook 4–5 minutes until translucent. Stir in garlic, Italian seasoning, and red pepper flakes for 30 seconds until fragrant.
2. Build the base: Add sun-dried tomatoes and zucchini. Cook 2–3 minutes to soften slightly. If using, add 1 teaspoon tomato oil for extra flavor.
3. Add chicken and broth: Pour in chicken broth. If using raw chicken, add it now. Bring to a gentle simmer. For raw chicken, simmer 12–15 minutes until cooked through, then remove and shred. Return shredded chicken to the pot.
4. Simmer and season: Add cooked shredded chicken (if not already in the pot). Simmer 5–7 minutes to let flavors mingle. Taste and season with salt and pepper.
5. Make it creamy: Reduce heat to low. Stir in heavy cream and Parmesan until melted and smooth. Do not boil after adding dairy to prevent separation.
6. Add greens and brighten: Stir in spinach until just wilted, 1–2 minutes. Add lemon juice and a little zest. Taste and adjust salt, pepper, and spice.
7. Finish and serve: Ladle into bowls. Top with extra Parmesan and chopped basil or parsley. A drizzle of olive oil on top is a nice touch.

How to Make It

1. Sweat the aromatics: Warm olive oil in a large pot over medium heat.

   Add onion with a pinch of salt. Cook 4–5 minutes until translucent. Stir in garlic, Italian seasoning, and red pepper flakes for 30 seconds until fragrant.

2. Build the base: Add sun-dried tomatoes and zucchini.

   Cook 2–3 minutes to soften slightly. If using, add 1 teaspoon tomato oil for extra flavor.

3. Add chicken and broth: Pour in chicken broth. If using raw chicken, add it now.

   Bring to a gentle simmer. For raw chicken, simmer 12–15 minutes until cooked through, then remove and shred. Return shredded chicken to the pot.

4. Simmer and season: Add cooked shredded chicken (if not already in the pot).

   Simmer 5–7 minutes to let flavors mingle. Taste and season with salt and pepper.

5. Make it creamy: Reduce heat to low. Stir in heavy cream and Parmesan until melted and smooth.

   Do not boil after adding dairy to prevent separation.

6. Add greens and brighten: Stir in spinach until just wilted, 1–2 minutes. Add lemon juice and a little zest. Taste and adjust salt, pepper, and spice.
7. Finish and serve: Ladle into bowls.

   Top with extra Parmesan and chopped basil or parsley. A drizzle of olive oil on top is a nice touch.

Keeping It Fresh

• Storage: Cool the soup completely, then store in airtight containers in the fridge for up to 4 days.
• Reheating: Warm gently on the stove over low heat. Avoid boiling to keep the cream from separating.

  Add a splash of broth if the soup thickens.

• Freezing: For best texture, freeze before adding cream and Parmesan. Thaw, reheat, then stir in the dairy and greens just before serving.

Benefits of This Recipe

• Low carb, satisfying: High in protein and healthy fats, with fiber-rich greens to keep you full.
• Quick meal prep: Rotisserie chicken makes this a 30-minute dinner with minimal fuss.
• Balanced nutrition: Protein from chicken, micronutrients from spinach and zucchini, and calcium from Parmesan.
• Restaurant-style flavor: Sun-dried tomatoes and Italian herbs give a gourmet feel without extra work.
• Family-friendly: Mild base with heat you can control. Easy to adapt for different tastes.

Common Mistakes to Avoid

• Boiling after adding cream: This can cause curdling.

  Keep the heat low once dairy is in.

• Skipping the seasoning: Taste as you go. A pinch of salt at each stage builds depth.
• Overcooking zucchini and spinach: Add them late to keep texture and color vibrant.
• Not using freshly grated Parmesan: Pre-grated can be clumpy and won’t melt as smoothly.
• Forgetting acid: A little lemon lifts the creaminess and balances the soup.

Recipe Variations

• Extra veggies: Add diced bell pepper, mushrooms, or riced cauliflower for more volume without extra carbs.
• Kale swap: Use chopped Tuscan kale instead of spinach. Simmer 5 minutes longer to soften.
• Bacon boost: Crisp 3–4 slices bacon first.

  Cook aromatics in the drippings, then crumble bacon on top.

• Dairy-light: Replace half the cream with unsweetened almond milk and add 2 ounces cream cheese for body.
• Spice it up: Stir in Calabrian chili paste or more red pepper flakes for heat.
• Herb-forward: Finish with fresh thyme and basil for a brighter, garden-fresh profile.
• Instant Pot method: Sauté aromatics, add broth and raw chicken, pressure cook 8 minutes, quick release, shred, stir in cream, Parmesan, and spinach on sauté low.

FAQ

Can I make this soup dairy-free?

Yes. Use full-fat coconut milk instead of cream and a dairy-free Parmesan alternative or nutritional yeast. The flavor will be slightly different but still rich and satisfying.

What can I use instead of sun-dried tomatoes?

Roasted red peppers or cherry tomatoes (halved) work well.

If using fresh tomatoes, sauté a minute longer to concentrate their flavor.

How do I keep the soup from separating?

Lower the heat before adding cream and cheese, and do not let it boil. Add dairy slowly while stirring. If it looks too hot, pull the pot off the burner for a minute, then continue.

Is this soup good for meal prep?

Definitely.

It reheats well and tastes even better the next day. Store in single-serve containers for quick lunches, and add a splash of broth when reheating if it thickens.

Can I use frozen spinach?

Yes. Thaw and squeeze out excess liquid before adding, or add it frozen and simmer a minute longer.

Adjust salt afterward since frozen greens can carry more water.

What cut of chicken is best?

Thighs stay juicier and add richness, while breasts are leaner. Both work. Rotisserie chicken is the fastest choice and adds a savory boost.

How can I thicken the soup without flour?

Let it simmer a few extra minutes uncovered to reduce, or stir in a few ounces of softened cream cheese.

Extra Parmesan also adds body.

Can I add pasta or rice for non–low carb eaters?

Sure. Cook pasta or rice separately and add to individual bowls before ladling in the soup. This keeps the base low carb and prevents sogginess.
