How to Make Lemon Chicken Orzo Soup
Making this soup is really straightforward – just cook your veggies, add the pasta, and finish with lemon.
Step 1: Sauté the Vegetables
Warm up 1 tablespoon olive oil in your pot, then toss in 1½ cups carrots, ½ cup celery, ½ cup onion, and 2 cloves garlic, stirring them around for 5-6 minutes till they get soft.
Step 2: Add Broth and Seasonings
Dump in 8 cups chicken broth, followed by ¾ cup orzo, 1 bay leaf, ½ teaspoon salt, ¼ teaspoon oregano, ¼ teaspoon basil, and ¼ teaspoon thyme into your pot.
Step 3: Simmer the Orzo
Let everything bubble gently for 10-12 minutes, giving it a stir now and then, until those little orzo pieces get tender but still have some bite left in them.
Step 4: Make Optional Roux (If Desired)
Want it thicker? Mix 3 tablespoons melted butter with 3 tablespoons flour until smooth, stir that into your soup, and let it bubble for 1-2 minutes till it thickens up.
Step 5: Add Chicken and Lemon
Stir in 2-3 cups cooked chicken and ¼-½ cup fresh lemon juice, then cook for 2-3 minutes till the chicken gets hot and all those flavors get cozy together.
Step 6: Season and Serve
Fish out that bay leaf, taste your soup, and add more salt and pepper if you think it needs some, then pour into bowls and top with your favorite goodies.

Tips for the Best Lemon Chicken Orzo Soup
These tips will help you nail this soup every time you make it.
- Start with Less Lemon: Pour in just ¼ cup first, taste it, then add more.
- Dice Vegetables Small: Tiny pieces cook faster and taste better in every spoonful.
- Use Rotisserie Chicken: Skip the chicken cooking and grab one from the store.
- Don’t Overcook Orzo: Check it at 10 minutes so it doesn’t turn to mush.
- Add Fresh Spinach: Throw in some chopped spinach at the end for extra goodness.
- Adjust Consistency: Got thick soup? Just add more broth till it looks right.
Variations and Substitutions
You can totally change this up based on what’s in your fridge or what you like.
- Use Different Pasta: Try tiny shells, ditalini, or even regular rice.
- Try Turkey Instead: Got leftover turkey? Perfect – use that instead of chicken.
- Make It Creamy: Stir in some heavy cream or Greek yogurt.
- Add More Vegetables: Zucchini, bell peppers, or mushrooms all work great here.
- Use Fresh Herbs: Swap dried herbs for fresh ones if you’ve got them.
- Skip the Roux: Leave it out if you want a lighter soup.
Make-Ahead and Storage Tips
Pop your leftover soup in containers and stick them in the fridge for up to 4 days. When you reheat it, go slow on the stove or use your microwave. The orzo soaks up broth while it sits, so you’ll probably need to add more liquid when warming it up.
You can freeze this soup for up to 3 months in freezer bags. Just thaw it in your fridge overnight before heating. The flavors get even better the next day – it’s like magic!
