Ingredients

  

• Olive oil or butter: 1 tablespoon for sautéing.
• Yellow onion: 1 medium, finely diced.
• Carrots: 2 medium, diced small.
• Celery: 2 ribs, diced small.
• Garlic: 3 cloves, minced.
• Broccoli: 5–6 cups florets (about 1 large head), chopped into small bite-size pieces.
• Cooked chicken breast: 2–3 cups, shredded or diced (rotisserie chicken works well).
• Low-sodium chicken broth: 6 cups.
• Milk: 1 cup (2% or whole for creamier texture; unsweetened almond milk works too).
• Plain Greek yogurt: 3/4 cup (2% or 0%).
• Sharp cheddar cheese: 1 1/2 to 2 cups, freshly shredded.
• All-purpose flour or cornstarch: 2 tablespoons (for thickening; use cornstarch for gluten-free).
• Dijon mustard: 1 teaspoon (boosts the cheddar flavor).
• Smoked paprika: 1/2 teaspoon (optional, for warmth and color).
• Salt and black pepper: To taste.
• Red pepper flakes: Pinch (optional, for a little heat).

Method

 

1. Prep your ingredients. Dice the onion, carrots, and celery. Chop the broccoli into small, even florets. Shred or dice your cooked chicken. Shred the cheddar. This makes the cooking flow smoothly.
2. Sauté the aromatics. Warm the olive oil or butter in a large pot over medium heat. Add onion, carrots, and celery with a pinch of salt. Cook 5–6 minutes, stirring, until softened. Add garlic and cook 30 seconds, until fragrant.
3. Build the base. Sprinkle in the flour and stir to coat the vegetables. Cook 1 minute to remove the raw flour taste. If using cornstarch, skip this step and make a slurry later.
4. Add liquids and broccoli. Slowly pour in the chicken broth while stirring. Add the broccoli, Dijon mustard, smoked paprika, and a little black pepper. Bring to a gentle simmer and cook 8–10 minutes, until the broccoli is tender but still bright green.
5. Thicken the soup. If you used flour earlier, the soup should already be slightly thick. If using cornstarch, whisk 2 tablespoons cornstarch with 2 tablespoons cool water to make a slurry, then stir it into the simmering soup and cook 2 minutes, until thickened.
6. Stir in the chicken. Add the shredded chicken and reduce heat to low. Let it warm through for 2–3 minutes.
7. Finish with dairy. Stir in the milk and reduce heat to the lowest setting. Gradually add the shredded cheddar by the handful, stirring until melted before adding more. Remove the pot from heat. Whisk the Greek yogurt in a bowl with a ladle of hot soup to temper it, then stir it back into the pot. Season with salt and pepper to taste. Add red pepper flakes if you like a little kick.
8. Adjust and serve. If the soup seems too thick, add a splash of broth or milk. If it’s too thin, simmer a few extra minutes. Ladle into bowls and top with a little extra cheddar or cracked pepper.

Keeping It Fresh

• Storage: Cool completely, then store in airtight containers in the fridge for up to 4 days.
• Reheating: Warm gently over low heat on the stove, stirring often. Avoid boiling after adding the cheese and yogurt to prevent curdling.
• Freezing: Dairy-based soups can separate when frozen. If you plan to freeze, cook the soup without cheese and yogurt, freeze for up to 2 months, and stir in dairy after reheating.
• Meal prep tip: Portion into individual containers for easy grab-and-go lunches.

Health Benefits

• High protein for satiety: Chicken and Greek yogurt help keep you full longer and support muscle maintenance.
• Vitamin-rich vegetables: Broccoli brings fiber, vitamin C, vitamin K, and antioxidants.

  Carrots add beta carotene and natural sweetness.

• Smarter creaminess: Using Greek yogurt and milk keeps the soup creamy with fewer saturated fats than heavy cream.
• Lower sodium option: Using low-sodium broth and seasoning to taste helps manage overall salt intake.

Common Mistakes to Avoid

• Boiling after adding dairy: High heat can cause the cheese or yogurt to separate. Keep it low and slow.
• Adding cheese all at once: Dumping in a big pile can lead to clumps. Add gradually and stir until smooth.
• Overcooking broccoli: Mushy broccoli loses color and texture.

  Simmer just until tender.

• Skipping the seasoning: Taste at the end and adjust salt, pepper, and mustard. Small tweaks make a big difference.
• Using pre-shredded cheese only: Bagged cheese often has anti-caking agents that don’t melt as smoothly. Freshly shredded melts better.

Recipe Variations

• Extra protein boost: Stir in 1/2 cup powdered milk or unflavored whey isolate at the end for even more protein.

  Add slowly and whisk well.

• Gluten-free: Use cornstarch or arrowroot instead of flour and confirm your broth is gluten-free.
• Low-carb: Skip the carrots and use heavy cream instead of milk if desired. Add cauliflower florets for extra body.
• Spicy version: Add 1 diced jalapeño with the aromatics and 1/2 teaspoon cayenne with the paprika.
• Bacon cheddar twist: Crisp 3–4 slices of turkey bacon or center-cut bacon, crumble, and stir in at the end for smoky flavor.
• Vegetarian swap: Replace chicken with a can of white beans and use vegetable broth. Add an extra 1/2 cup cheddar to keep protein higher.
• Slow cooker method: Add onion, carrots, celery, broccoli, broth, mustard, paprika, salt, and pepper to the slow cooker.

  Cook on Low 4–5 hours. Stir in cooked chicken, milk, and cheese until melted. Temper and add yogurt at the end.

FAQ

Can I use frozen broccoli?

Yes.

Add frozen florets directly to the simmering broth and extend the cooking time by a few minutes. They work well, but chop any large pieces so everything cooks evenly.

What kind of cheddar works best?

Sharp or extra-sharp cheddar delivers the most flavor with less cheese. Grate it yourself for the smoothest melt.

A small amount of Gruyère can add depth if you have it.

How do I prevent the yogurt from curdling?

Keep the heat low and temper the yogurt first. Whisk it with a warm ladle of soup, then stir it back into the pot off the heat. Avoid boiling after it’s added.

Can I make it dairy-free?

Yes.

Use olive oil, unsweetened almond or cashew milk, and a dairy-free cheddar that melts well. Skip the yogurt or use a plain, unsweetened dairy-free yogurt at the end.

Is rotisserie chicken okay?

Absolutely. It’s a time-saver and adds good flavor.

Remove the skin, shred the breast meat, and fold it in during the final minutes.

How can I thicken the soup without flour or cornstarch?

Blend a cup or two of the soup (without the chicken) and stir it back in. You can also add a few small cauliflower florets early on and let them break down naturally.

What’s a good side to serve with this?

A slice of whole-grain toast, a simple green salad, or a piece of crusty bread pairs nicely. For extra protein, add a hard-boiled egg on the side.

Final Thoughts

High Protein Broccoli Cheddar Chicken Soup is proof that comfort food can still be smart, simple, and nourishing.
