Chicken Noodle Soup with Poached Breast and Fennel
A whole chicken breast gently poached in broth gives this soup tender pieces of meat without a separate frying step. Fennel, red and white onion, and colorful carrots bring sweetness to the pot. Keep the simmer quiet and add the small pasta near the end: the vegetables should be soft, the chicken easy to cut, and plenty of broth still visible around the noodles.

A chicken soup built around fennel
Chicken noodle soup combines chicken, vegetables and pasta in a savory broth. This version uses a raw boneless breast poached directly in the soup, with fennel in place of celery and small pasta shapes instead of long noodles. It makes a warm lunch in winter and a useful, uncomplicated supper throughout the year.
This recipe is based on my YouTube video, with a few adjustments since publication. The chicken weight, initial broth quantity and approximate total vegetable weight come from the video; the individual vegetable and pasta measures below make the less precise parts easier to reproduce. Cooking follows the chicken’s internal temperature and the pasta package time rather than one fixed simmer for everything. The video’s 45-minute chicken cook can be excessive for a breast this size. Its fixed salt and pepper additions are also heavy for the stated broth quantity, so this version starts with much less pepper and adds salt only after tasting.
I make it this way because poaching keeps the preparation in one pot and lets the broth season the meat. It is a different starting point from soup made with rotisserie chicken, where the chicken only needs reheating. There is no cream or thickener here, either. For a grain-based bowl, chicken and wild rice soup follows its own cooking schedule.
Ingredients and the balance in the pot
For six soup portions, use:
10 1/2 ounces boneless, skinless chicken breast, one large breast
8 1/2 cups low-sodium chicken broth, plus up to 4 1/4 cups extra as needed
1 tablespoon olive oil
2 small red onions and 2 small white onions, about 17 1/2 ounces combined, diced
9 ounces trimmed fennel bulb, about 1 small bulb, diced
9 ounces carrots, peeled and cut into 1/4-inch rounds
5 1/4 ounces dried small pasta, such as mini shells or small macaroni
1/4 teaspoon ground black pepper, plus more to taste
Fine salt to taste, starting with up to 1/2 teaspoon only if needed
1/4 cup chopped flat-leaf parsley
The fennel bulb is the vegetable to measure, after removing tough stalks and the firm core. Its mild anise aroma softens as it cooks. Red onion can tint the broth slightly, and purple carrots may darken it more; neither means the soup has gone wrong. Ordinary orange carrots are fine.
Small pasta shapes fit a spoon comfortably. The colorful shapes in the video are a visual choice, not a requirement. Weigh the dry pasta rather than filling a measuring jug to the same level: shells and macaroni pack differently. This moderate quantity leaves room for broth instead of producing a pot of wet pasta.
The broth matters more than a long list of herbs. Homemade chicken stock concentrate must be diluted to ordinary broth strength; homemade chicken bouillon cubes also need their intended amount of water. Taste before adding salt, especially with commercial broth. Extra broth is a reserve, not an instruction to pour in every last cup.
Make the soup in six stages
1. Prepare evenly sized vegetables
Dice the onions and the trimmed fennel into small pieces. Slice the carrots into thin rounds, cutting thicker carrots lengthwise first. Keep everything close to the same size so one spoonful does not contain soft onion and a hard chunk of carrot. Pat the chicken dry and keep it separate from the prepared vegetables.
2. Sweat the vegetables without browning
Heat the olive oil in a large soup pot over medium heat. Add the onions, fennel and carrots. Cook for 6 to 8 minutes, stirring regularly, until the onion turns translucent and the vegetables smell sweet. They should hiss gently, not fry hard. Lower the heat if the onion edges start turning brown.
3. Prepare the broth
If using homemade broth that still contains bones or aromatics, strain it through a fine sieve into a heatproof container. For ready-to-use broth, simply measure it. Add the initial 8 1/2 cups to the vegetables, along with the pepper. Bring to a gentle simmer. Keep the additional broth nearby for adjustments later.
4. Poach the whole breast gently
Lower the chicken breast into the simmering broth. It should be submerged; use a little reserved broth if necessary. Partly cover the pot and maintain occasional small bubbles. Start checking after 12 minutes; a large breast may need roughly 15 to 20 minutes or longer, depending on thickness and starting temperature. The thickest part must reach 165°F before removal. Time and white-looking meat alone are insufficient checks.
5. Cut the chicken and cook the pasta
Transfer the cooked breast to a clean board. Let it rest briefly, then slice and cut into spoon-sized pieces. Check the carrots: they should be tender or nearly so before adding pasta. Stir the dry pasta into the simmering soup and cook for its package time, often 8 to 10 minutes. Stir occasionally so the shapes do not settle and stick. Return the chicken during the final minute to warm through.
I prefer to take the breast out while the pasta cooks because it has already reached its cooking temperature. A long second simmer can make those clean-cut pieces stringy. For a separate chicken meal with a richer sauce, creamy chicken vol-au-vent uses a different finish.
6. Adjust the broth and finish with parsley
Taste a noodle. It should be tender with a little resistance, without a chalky center. Add hot reserved broth in small amounts if evaporation or pasta absorption has crowded the pot. Bring the soup back to a gentle simmer, taste again, then adjust salt and pepper. Stir in the parsley immediately before serving. Leave enough liquid that a ladle lifts broth along with the solids.
Keep the noodles from taking over
The main mistake is treating pasta like a vegetable that can sit in hot broth indefinitely. It continues absorbing liquid after the heat is off. Serve promptly, and avoid leaving the finished pot simmering while preparing another dish.
For planned leftovers, cook the pasta separately and put a portion in each bowl before adding the chicken and vegetable broth. That same distinction matters in minestrone with pasta and beans. Separating the starch gives more control over the following day’s texture.
Substitutions
Celery can replace the fennel by the same prepared weight, though the flavor becomes more familiar and less aromatic. Use only white or yellow onion if that is what you have. Turkey breast can replace chicken, but its thickness changes the poaching time; still check the center with a thermometer.
For already cooked chicken, skip the poaching stage. Simmer the vegetables until nearly tender, cook the pasta, then add the meat near the end and heat it thoroughly to 165°F. If you have a larger supply of leftovers, classic chicken pot pie offers another way to use them. Do not replace the pasta with raw rice using the same timing.
Questions about poaching and storage
Can I use a frozen breast?
Thaw it in the refrigerator first for this method. A frozen center makes the timing less predictable and can leave the vegetables cooking far longer while the meat catches up.
Why is my soup cloudy?
Pasta releases starch into the broth. A slight haze is expected and does not mean it has spoiled. A vigorous boil and repeated stirring can make the broth cloudier and break the vegetables. For a clearer finish, cook the pasta separately.
How long does it keep?
Cool promptly in shallow containers and refrigerate within two hours. Keep refrigerated soup for 3 to 4 days and reheat portions to 165°F. If using previously cooked chicken, count storage from its original cooking day. Freeze the soup without pasta for better texture, then add freshly cooked pasta after thawing and reheating.
A simple meal alongside the soup
Chicken supplies protein, while the pasta and vegetables make the bowl more substantial. This is a broth-based meal; its sodium level depends largely on the stock and added salt. Six portions work as soup servings, or divide the pot into four larger bowls for a light main meal.
A slice of homemade white bread is enough alongside. For a crisp accompaniment, try air-fryer garlic bread. A green salad dressed with lemon vinaigrette brings a fresh contrast without adding another heavy dish. For other textures and ingredients, browse the collection of comforting soup recipes.
