Lemon chicken orzo soup is chicken soup with a job: it feeds six people from one pot in under an hour. The lemon goes in off the heat so it stays bright instead of bitter.
You build the base by browning chicken thighs in the pot first, then simmering them with carrot, celery, and garlic until the meat pulls apart with a fork. Orzo cooks right in the broth, so the starch thickens the liquid without cream.
The finish is a tempered egg-lemon mixture whisked into the hot broth. It goes silky in about 30 seconds. Get the pan hot and trust the process.

About the Ingredients
1 1/2 lb (680g) boneless, skinless chicken thighs
Thighs stay juicy through a 20-minute simmer where breasts dry out. Swap in bone-in thighs for a richer broth, but add 10 minutes to the simmer and shred the meat off the bone.
2 tbsp (30ml) olive oil
Regular olive oil, not extra virgin, holds up to browning heat. Use avocado oil if you have it; both have a smoke point above 400F (204C).
1 medium yellow onion, diced (about 1 1/2 cups)
Yellow onion gives the sweetest base after browning. Sweet onion works if you want a milder broth, and shallots are fine in a pinch.
2 medium carrots, peeled and diced (about 1 cup)
Cut them to 1/2-inch (1.3cm) dice so they finish at the same time as the celery. Buy carrots with the tops still attached if you can, since they are fresher and sweeter.
2 celery stalks, diced (about 3/4 cup)
Use the inner stalks for tenderness, and save the leaves to stir in at the end. Fennel is a good swap if you want an anise note.
4 garlic cloves, minced (about 1 tbsp)
Fresh garlic only here, since jarred garlic tastes flat after simmering. Add it last in the saute so it does not scorch at 400F (204C).
8 cups (1.9L) low-sodium chicken broth
Low-sodium lets you control the salt, and you will need it because orzo absorbs salt as it cooks. Better Than Bouillon at half strength is a solid substitute.
1 cup (180g) dried orzo
Orzo is rice-shaped pasta, not rice, so do not substitute white rice unless you add 10 minutes of cook time. Risoni is the same product under another name.
2 large eggs, at room temperature
Room-temperature eggs temper more smoothly and are less likely to scramble. Let them sit in warm water for 5 minutes if you forgot to pull them out.
1/3 cup (75ml) fresh lemon juice, from about 2 lemons
Squeeze it fresh; bottled lemon juice tastes metallic in a broth this light. Roll the lemons on the counter first to get more juice out.
1 tsp kosher salt, plus more to taste
Kosher salt dissolves evenly and seasons more predictably than table salt. Taste after the egg goes in, since it dulls the salt slightly.
1/2 tsp black pepper, plus chopped fresh dill and lemon slices to serve
Fresh dill is the classic garnish, but flat-leaf parsley or thyme works. Add the herbs off the heat so they stay green.
Tips & Tricks
Temper the eggs or you get egg drop soup
Whisk a ladle of hot broth into the egg-lemon mixture in a slow stream before it goes back in the pot. Adding cold eggs straight to hot broth scrambles them in seconds.
Cook the orzo in the pot, not separately
The starch the orzo releases is what thickens the broth. Boiling it in a separate pot leaves you with thin soup and a second dirty pan.
Pull the chicken at 165F (74C)
Check the thickest thigh with an instant-read thermometer. Overcooked thighs turn stringy and shred into mush.
Do not boil after the eggs go in
Keep the pot at a bare simmer, 185F to 195F (85C to 90C), once the egg mixture is in. A rolling boil breaks the emulsion and makes the broth grainy.
Pro Tips
Step-by-Step Instructions
1. Season and brown the chicken
Pat the thighs dry, season with 1/2 tsp of the salt and the pepper, and sear in the olive oil in a Dutch oven over medium-high heat at 400F (204C) for 5 to 6 minutes per side. They are done when deeply golden brown and an instant-read thermometer reads 165F (74C) at the thickest point. Move them to a plate.
2. Soften the aromatics
Lower the heat to medium, add the onion, carrot, and celery, and cook for 6 to 7 minutes until the onion is translucent and the edges of the carrot look glossy. Add the garlic and stir for 45 seconds, just until fragrant, not browned.
3. Simmer the broth
Pour in the broth and scrape the browned bits off the bottom with a wooden spoon. Return the chicken to the pot, bring to a boil, then reduce to a simmer at 195F (90C) and cook uncovered for 20 minutes.
4. Shred the chicken
Lift the thighs out with tongs and shred with two forks. The meat should pull apart with no resistance. Set it aside and keep the broth at a bare simmer.
5. Cook the orzo
Stir the orzo into the simmering broth and cook at 195F (90C) for 9 to 10 minutes, stirring twice. It is done when the orzo is tender with a slight bite and the broth has thickened enough to coat a spoon.
6. Temper the egg and lemon
Whisk the eggs and lemon juice in a bowl until smooth. Slowly ladle in 1 cup of hot broth while whisking constantly, then pour the mixture back into the pot off the heat.
7. Finish and serve
Return the shredded chicken to the pot, stir in the remaining 1/2 tsp salt, and taste. The broth should be silky, not grainy, and bright at the back of the throat. Serve with dill and lemon slices.
Delicious Variations
Greek-style with spinach
Stir 3 cups of baby spinach into the hot soup off the heat and let it wilt for 2 minutes. Add 1/4 cup crumbled feta per bowl.
Spicy harissa version
Whisk 1 tbsp harissa paste into the aromatics with the garlic. Skip the dill and finish with chopped cilantro and a squeeze of lime.
Mushroom and lemon
Swap the chicken for 12 oz (340g) sliced cremini mushrooms and use vegetable broth. Brown the mushrooms hard first, since they need the color the chicken would have given.
How to Store Lemon Chicken Orzo Soup
Refrigerator
Store in an airtight container for up to 4 days. The orzo will absorb broth as it sits, so thin with 1/2 cup broth or water when reheating.
Freezer
Freeze the soup base without the orzo and egg for up to 3 months. Cook fresh orzo and temper fresh eggs when you reheat it, since frozen orzo turns to mush.
Reheating
Warm gently over medium-low heat at 185F (85C), stirring often, until steaming but not boiling. Do not let it come to a rolling boil or the egg finish will break.
Frequently Asked Questions
Q: Can I make lemon chicken orzo soup in a slow cooker?
Yes, but brown the chicken and vegetables in a skillet first, since the slow cooker will not give you that color. Cook on low for 4 hours, then add cooked orzo and the tempered egg mixture at the end.
Make this pot on a cold night and you will stop buying canned chicken soup. Get the pan hot and trust the process.
