Aromatic Lemon Chicken Orzo Soup

Here is my favorite lemon chicken orzo soup recipe, with tender chicken, fresh vegetables, and orzo pasta in a light, lemony broth that’s perfect for any day of the week.

This soup has become our go-to dinner when someone in the house is feeling under the weather or when we just need something warm and comforting. I love that it comes together in one pot and tastes even better the next day for lunch.

What Kind of Chicken Should I Use?

For this soup, boneless, skinless chicken breasts are the easiest option since they cook quickly and shred nicely into bite-sized pieces. That said, chicken thighs work just as well and actually stay a bit more tender and juicy if you accidentally overcook them. You can use fresh or frozen chicken breasts – if using frozen, just add about 5-10 extra minutes to your cooking time to make sure they’re cooked through. Some people even like to use a rotisserie chicken from the store to save time, which you can just shred and add toward the end of cooking.

Options for Substitutions

This soup is pretty forgiving when it comes to swaps, so here are some options if you need to make changes:

• Orzo: If you don’t have orzo, you can use other small pasta shapes like ditalini, acini de pepe, or even broken spaghetti. Rice also works well – just add it earlier in the cooking process since it takes longer to cook than orzo.
• Chicken breasts: Chicken thighs are a great swap here and actually add more flavor to the soup. You can also use rotisserie chicken – just shred it and add it near the end of cooking to warm through.
• Fresh lemon juice: Bottled lemon juice works in a pinch, though fresh tastes better. You can also add some lemon zest along with the juice for extra flavor.
• Chicken broth: Vegetable broth can replace chicken broth if needed, though the soup will have a lighter flavor. You might want to add an extra bouillon cube or some extra seasoning to compensate.
• Fresh parsley: Dried parsley works fine – just use about 1 teaspoon instead of the tablespoon. Fresh dill is also a nice option that pairs well with lemon.
• Butter and olive oil: You can use all butter or all olive oil if that’s what you have on hand. The combination just adds a nice flavor balance.

Watch Out for These Mistakes While Cooking

The biggest mistake when making lemon chicken orzo soup is adding the orzo too early, which causes it to absorb too much liquid and turn mushy – wait until the chicken is fully cooked before stirring in the pasta.

Another common issue is overcooking the chicken breasts, so pull them out as soon as they reach 155°F internally, then let them rest while the orzo cooks before shredding or cutting them up.

Don’t add the lemon juice at the beginning of cooking, as heat can make it taste bitter – always stir it in at the very end to keep that bright, fresh flavor.

If you’re planning to store leftovers, keep in mind that orzo continues to soak up broth as it sits, so you may want to cook the pasta separately and add it to individual bowls, or plan to add extra broth when reheating.

What to Serve With Lemon Chicken Orzo Soup?

This soup is pretty hearty on its own since it’s loaded with chicken, orzo, and veggies, but I love serving it with some warm crusty bread or dinner rolls for soaking up the lemony broth. A simple side salad with mixed greens, cucumbers, and a light vinaigrette keeps things fresh without weighing you down. If you want to make it more of a meal, garlic bread or cheesy breadsticks are always a hit with my family. Since the soup has a bright, citrusy flavor, it pairs really well with something simple and not too heavy on the side.

Storage Instructions

Store: Keep your lemon chicken orzo soup in an airtight container in the fridge for up to 4 days. Just a heads up – the orzo will soak up some of the broth as it sits, so the soup gets thicker over time. You can thin it out with a bit of extra chicken broth when reheating if you’d like.

Freeze: This soup freezes pretty well for up to 3 months, though I’ll be honest – the orzo texture changes a bit after freezing. If you know you’ll be freezing it, consider cooking the orzo separately and adding it fresh when you reheat. Otherwise, just freeze it all together in freezer-safe containers and it’ll still taste great.

Reheat: Warm it up gently on the stovetop over medium-low heat, stirring occasionally until heated through. Add a splash of chicken broth or water if it’s gotten too thick. You can also microwave individual portions, but I like to add a squeeze of fresh lemon juice after reheating to brighten up the flavors again.

• Calories: 1200-1350

• Fat: 28-35 g
• Carbohydrates: 115-130 g

Ingredients

• 3 celery sticks (finely diced into 1/4-inch pieces)
• 3 carrots (peeled and sliced into 1/4-inch rounds)
• 1/2 large onion
• 1 tbsp butter (I prefer Kerrygold unsalted butter for this)
• 1 tbsp olive oil
• 4 garlic cloves (freshly minced for best flavor)
• 2 tbsp flour
• 6 cups chicken broth (I always use Swanson for consistent salt levels)
• 1/2 tsp Italian seasoning
• 1 bay leaf
• 1.5 lb chicken breasts (cut into 1-inch bite-sized cubes)
• 1 1/4 cups orzo
• 1 tbsp lemon juice
• 1 tbsp fresh parsley
• salt
• pepper

Step 1: Prepare Mise en Place and Sear the Chicken

• 3 celery sticks
• 3 carrots
• 1/2 large onion
• 4 garlic cloves
• 1 tbsp butter
• 1 tbsp olive oil
• 1.5 lb chicken breasts
• salt
• pepper

Dice the celery into 1/4-inch pieces, slice the carrots into 1/4-inch rounds, and mince the onion and garlic cloves—having everything prepped before you start cooking ensures the soup comes together smoothly.

While you’re prepping, pat the chicken breast cubes dry with paper towels and season them lightly with salt and pepper.

Heat the butter and olive oil in a large pot or Dutch oven over medium-high heat until the butter is foaming, then add the chicken cubes in a single layer.

Let them sear undisturbed for 2-3 minutes per side until golden brown on the outside (they don’t need to be cooked through).

Transfer the seared chicken to a plate and set aside—this browning step builds deep flavor into the broth.

Step 2: Build the Aromatic Base with a Roux

• 3 celery sticks
• 3 carrots
• 1/2 large onion
• 4 garlic cloves
• 2 tbsp flour

In the same pot with the rendered fat, add the diced celery, sliced carrots, and minced onion over medium heat.

Sauté for 5-7 minutes, stirring occasionally, until the vegetables soften and the onion becomes translucent.

Add the minced garlic and cook for 30 seconds until fragrant, then sprinkle the flour over the vegetables and stir constantly for 1 minute.

This creates a light roux that will help thicken the soup and give it a silky mouthfeel.

Step 3: Build and Simmer the Broth

• 6 cups chicken broth
• 1/2 tsp Italian seasoning
• 1 bay leaf
• seared chicken from Step 1

Pour the chicken broth into the pot, scraping the bottom with a wooden spoon to release any browned bits stuck to the pan—these add incredible depth.

Add the Italian seasoning and bay leaf, then return the seared chicken to the pot along with any accumulated juices.

Bring the soup to a boil over high heat, then reduce to a gentle simmer, cover partially, and cook for 15 minutes.

The chicken will finish cooking through in the simmering broth while the flavors meld together.

Step 4: Add the Orzo and Cook Through

• 1 1/4 cups orzo

Stir the orzo directly into the simmering soup and cook uncovered for 10 minutes, stirring occasionally to prevent sticking.

The orzo will absorb some of the flavorful broth as it cooks—I like to give it a stir halfway through to ensure even cooking.

The pasta should be tender but still have a slight bite to it when done.

Step 5: Finish with Bright Citrus and Fresh Herbs

• 1 tbsp lemon juice
• 1 tbsp fresh parsley
• salt
• pepper

Remove the pot from heat and stir in the lemon juice and fresh parsley.

Taste the soup and season with additional salt and pepper to your preference—I always taste before adding salt since the broth already contains some.

Remove the bay leaf before serving.

The lemon juice adds a bright, fresh note that brings all the flavors into focus without overpowering the delicate chicken and herbs.
