A warm bowl of chicken orzo soup with carrots and fresh herbs, made with pasture-raised chicken and served in a white bowl on a wooden surface.

In the winter, I like meals that are straightforward and don’t take much thought. Chicken soup is usually one of the first things I make.

Many people think homemade soup requires a lot of work, but it’s one of the easiest ways to feed a family without much cost or stress. When the base of the soup is pasture-raised chicken, the nutrition is built in. The vegetables, broth, and a small amount of lemon bring everything together in a straightforward way.

Some people prefer a lower-carb approach. If that’s the case, the traditional orzo can be swapped for keto-friendly orzo without changing the structure of the recipe.

FAQ: Chicken Orzo Soup

Can I make this soup keto?

Yes. You can replace traditional orzo with any low-carb orzo alternative. It keeps the same basic feel without adding extra carbohydrates.

Does pasture-raised chicken make a difference in soup?

It does. Chickens raised on grass and fresh forage tend to offer steady, natural nutrient density. This often results in broth and meat with a cleaner character, without relying on additives.

Can I use leftover cooked chicken?

Yes. Pulled, diced, or roasted chicken all work well. This recipe is a practical way to use leftovers without waste.

What if I want a thicker soup?

You can simmer the soup longer with the lid off, or add a small amount of extra orzo. Keto orzo will also thicken the broth as it cooks.

Can I make this ahead?

Yes. The soup keeps well in the refrigerator for 3–4 days. If using regular orzo, it will continue to absorb liquid, so you may want to add a small amount of extra broth when reheating.

How do I avoid UPFs in seasonings?

Many packaged Italian seasoning blends contain additives, anti-caking agents, or processing sprays. If you're avoiding UPFs, you can mix your own herbs from single-ingredient dried herbs.

How do I make my own Italian seasoning?

You can mix equal parts of: basil, oregano, thyme, rosemary, marjoram, and parsley.
A simple version is 1 tablespoon each of basil, oregano, thyme, and rosemary.

Does homemade Italian seasoning taste different?

It tastes straightforward and clean. Without stabilizers or anti-caking agents, the herbs keep their natural character.
