This Lemon Chicken Orzo Soup is one of those simple recipes that manages to be both comforting and fresh. Tender chicken, carrots, fennel and orzo simmer in chicken broth, then a generous squeeze of lemon and fresh dill brighten everything up just before serving.
I first discovered this recipe years ago in a Weight Watchers Weekly handout and have loved it ever since. It’s essentially a lighter, brighter cousin of classic chicken noodle soup—and because it starts with already-cooked chicken, it’s on the table in less than 30 minutes.
It’s especially good when you have leftover or rotisserie chicken in the refrigerator and want to turn it into something completely different.

Why I Love This Chicken Orzo Soup
- Quick and easy — One pot and less than 30 minutes from start to finish.
- Fresh and comforting — Lemon and dill give familiar chicken soup a wonderfully bright flavor.
- Great for leftover chicken — Cooked or otisserie chicken makes this especially easy.
- Light but satisfying — Chicken, vegetables and a little orzo make it filling without feeling heavy.
- Easy to adapt — No fennel? Use celery. No orzo? Another small pasta works just fine.
- WW friendly — A generous 1¼-cup serving has just 201 calories and 3 Points.
Ingredients and Easy Substitutions
You only need a handful of simple ingredients.
Reduced-Sodium Chicken Broth — The foundation of the soup. Using reduced-sodium broth lets you control the seasoning yourself.
Carrots — Add sweetness, color and familiar chicken-soup flavor.
Fennel — Fennel gives this soup a subtle aromatic flavor that works beautifully with lemon and dill. If you don’t have fennel—or simply don’t care for it—celery is an easy substitute.
Orzo — This tiny rice-shaped pasta is perfect for soup. Ditalini, small shells or another small pasta can be substituted.
Cooked Chicken Breast — Leftover baked, grilled, poached or rotisserie chicken all work. This is a great recipe for using up whatever cooked chicken you already have.
Fresh Lemon Juice — This is what makes the soup special. Add it at the end so its bright flavor doesn’t get lost during cooking.
Fresh Dill — Dill is wonderful with both chicken and lemon. Fresh parsley also works if that’s what you have.
Salt and Black Pepper — Season according to the saltiness of your broth and your own taste.

How to Make Lemon Chicken Orzo Soup
Step 1: Start the broth
In a large soup pot, bring the chicken broth, salt and pepper to a boil over high heat.
Step 2: Add the vegetables and orzo
Stir in the carrots, fennel and orzo. Return to a boil, then reduce the heat and simmer, partially covered, for 8 to 10 minutes, or until the vegetables and orzo are tender.
Step 3: Add the chicken
Stir in the cooked chicken and simmer for another minute or two, just until heated through.
Step 4: Finish with lemon and dill
Remove the pot from the heat before stirring in the fresh lemon juice and dill.
Taste and add more lemon, dill, salt or pepper as needed.
That’s it. Dinner is ready.
Martha’s Tips for the Best Chicken Orzo Soup
Add the lemon at the end. Fresh lemon juice loses some of its brightness when cooked for too long. Stirring it in after removing the soup from the heat gives you a much fresher flavor.
Don’t overcook the orzo. Small pasta cooks quickly and will continue absorbing broth as the soup sits.
Use rotisserie chicken for an easy shortcut. It’s one of my favorite ways to turn leftover chicken into an entirely new meal.
Keep extra broth handy. The orzo will absorb liquid as it sits, so leftovers will usually be thicker than the freshly made soup. Just add a splash of broth when reheating.
Taste before adding more salt. Chicken broth and rotisserie chicken can both contain quite a bit of sodium.
What Is Orzo?
Despite looking a lot like rice, orzo is actually pasta. Its small rice-like shape makes it especially good for soups because it’s substantial enough to make them satisfying without overwhelming the other ingredients.
You’ll usually find orzo alongside other dried pasta at the grocery store.
If you don’t have it, substitute another small pasta such as ditalini, small shells, acini di pepe or even broken spaghetti.
What About the Fennel?
If fennel isn’t something you normally cook with, don’t let it keep you from making this soup.
Fresh fennel has a mild licorice-like flavor when raw, but that flavor becomes much softer and sweeter as it cooks. It’s particularly good with lemon, chicken and dill.
To prepare it, cut off the stalks and feathery fronds, slice the bulb in half lengthwise and remove the tough triangular core. Thinly slice or chop the remaining bulb.
And if fennel simply isn’t your thing, substitute a couple of thinly sliced celery stalks. The soup will still be delicious.
Easy Variations
This simple soup is also easy to change depending on what you have.
- Add more vegetables: Stir in frozen peas, baby spinach or chopped zucchini.
- Use another pasta: Ditalini, small shells or any other small pasta will work.
- Make it gluten-free: Use your favorite gluten-free small pasta or substitute cooked rice.
- Use leftover turkey: This is a great soup to remember after Thanksgiving.
- Change the herbs: Substitute fresh parsley for dill or add a little of both.
- Make half a batch: The recipe is easy to cut in half if you’re cooking for one or two and don’t want lots of leftovers.
What to Serve with Lemon Chicken Orzo Soup
Because the soup already contains chicken, pasta and vegetables, it doesn’t need much to turn it into a meal.
I like it with:
- A slice of crusty or whole-grain bread
- Toasted pita
- A simple green salad with lemon vinaigrette
- Half a sandwich
- Crackers and a piece of fresh fruit
For lunch, a warm bowl of this soup with a few crackers is often plenty for me.
Storage and Reheating
Refrigerator: Store leftover soup in an airtight container in the refrigerator for up to 4 days.
Freezer: You can freeze the soup for up to 3 months, although the orzo will become softer after freezing and thawing.
Reheating: Warm gently on the stovetop or in the microwave (affiliate link). Since the orzo continues to absorb broth while sitting, you’ll probably want to add a splash of chicken broth or water when reheating.
A Make-Ahead Tip
If you’re intentionally making this soup for meal prep or freezing, consider cooking the orzo separately and adding it to individual bowls as you serve them. This prevents the pasta from continuing to absorb the broth and becoming overly soft.

Variations and Substitutions
- Fennel flavor: Fennel is a bulbous vegetable with a mild licorice-like taste that mellows beautifully when cooked. It adds a fresh, aromatic note that brightens the soup without overpowering it.
- How to slice fennel: Trim away the stalks and feathery fronds, then cut the bulb in half lengthwise. Remove the tough core with a small triangle cut. Slice each half thinly and then chop if smaller pieces are desired.
- No fennel: Simply use 2 thinly sliced celery stalks for a similar crunch and texture.
- Extra veggies: Frozen peas, spinach, or zucchini can be added for extra bulk and nutrition.
- Pasta swaps: If you don’t have orzo, any small pasta shape works—ditalini, mini shells, or even couscous.

- Gluten-Free: Substitute gluten-free pasta or cooked rice.

I make it all the time. Our favorite!?
I tried the Hamburger Stew. It was very good even two days later it is still good. Thank You for the soup recipes. I love soup.
Every recipe I try is simple to prepare…and simply delicious! Your Chicken Orzo Soup, however, is one of the most outstanding – amazingly flavorful! I also want to add the fact that my husband is also a fan! Thank you, Martha!

Since discovering this recipe, I’ve made this delicious soup twice, and I doubled the recipe the second time. This will be my go-to chicken soup. I can’t believe how such a simple recipe that doesn’t take much cooking time can be so flavorful. I’m also going to make it now and then without the orzo, just to be able to enjoy that delicious broth whenever I want to, and with even fewer WW points. Love all your recipes…thank you!
But you do have to have a smart phone and you do need to track points. I don’t see much differecet. if you take away fat, sugar is added or in ww case fake stevia. if you take away sugar you add fat. You could save up points below also
I have made thissoup several times. So good. I have made it a coupledifferent ways…one-time I used onion and another timeI used leeks.. Ithas been good every time.
I got this recipe in one of our WW pamphlets. I really like this soup. If I don’t have fennel I have add onion and shredded carrots. I have also made it without the dill.it is a very delicious soup just about anyway you make it. Thanks for the tips and recipes.
I love fennel this time of year! It adds such a bright note when everything seems so muted and gray.
Can’t wait to try this recipe.
