Pho is a Vietnamese noodle soup that has become popular worldwide. The dish consists of four main parts: the broth, rice noodles, protein, and fresh herbs and vegetables. Understanding each component helps you recreate authentic pho at home.

The broth is the foundation of pho and typically simmers for 12 to 24 hours. Traditional pho broth uses either beef bones (for pho bo) or chicken bones (for pho ga). The long cooking time allows flavors from the bones, spices, and aromatics to develop fully. A proper broth should be clear, aromatic, and slightly sweet from the natural collagen and marrow in the bones.
Rice noodles are the second essential component. These thin, delicate noodles are made from rice flour and water. They differ from wheat noodles and have a tender texture when cooked. Fresh rice noodles can be purchased at Asian markets or made from scratch, though homemade versions require special equipment and practice.
Protein options vary by regional preference and personal choice. Beef pho traditionally uses thin slices of raw beef that cook in the hot broth, along with beef brisket or tendon for added flavor. Chicken pho uses shredded or sliced cooked chicken. Vegetarian versions substitute mushrooms, tofu, or additional vegetables.
Fresh herbs and vegetables are served on the side, allowing each person to customize their bowl. Common additions include fresh basil, cilantro, lime wedges, jalapeños, bean sprouts, and white onions. This customization aspect is central to the pho experience.
Takeaway: Spend time gathering quality ingredients before cooking. Visit an Asian market to find authentic rice noodles and specialty items like star anise and cinnamon. Understanding what goes into pho helps you make informed choices about which components to prioritize based on your kitchen skills and available time.
Creating pho broth at home is a time-intensive process but manageable with planning. The broth-making process begins with selecting bones. Beef bones for pho bo should include knuckle bones, leg bones with marrow, and oxtail. These bones contain collagen that transforms into gelatin during cooking, creating a rich, slightly viscous broth. Many butcher shops can order these bones in advance or have them available. Plan to use approximately 3 to 4 pounds of bones per gallon of water.

Before cooking, blanch the bones by placing them in boiling water for 3 to 5 minutes, then rinsing them under cold water. This removes impurities and proteins that cloud the broth. This step is crucial for achieving the clear appearance that characterizes quality pho broth.
After blanching, place the bones in a large pot with fresh cold water. Bring the water to a boil, then reduce heat to maintain a gentle simmer. Add aromatics at this stage: one 3-inch piece of ginger (halved lengthwise and lightly charred on a stovetop), one large white onion (halved and charred), and 3 to 4 star anise. Other spices include one 3-inch cinnamon stick, 3 to 4 cloves, one bay leaf, and 1 teaspoon of coriander seeds. Add rock sugar (about 1 to 2 tablespoons) to balance flavors. Let the broth simmer for at least 12 hours, though 24 hours produces deeper flavor.
Throughout the simmering process, skim foam and impurities that rise to the surface, particularly during the first 2 to 3 hours. Use a fine mesh strainer or skimmer. Every hour or two during the first half of cooking, check that the broth maintains a gentle simmer—it should barely bubble.
Toward the end of cooking, add fish sauce (about 2 to 3 tablespoons per gallon) and salt to taste. Strain the finished broth through cheesecloth or a fine mesh strainer into clean containers. The broth can be refrigerated for up to 5 days or frozen for several months. Fat will solidify on top when chilled and can be removed or left in place depending on preference.
Takeaway: Plan your pho cooking around the broth timeline. Make broth on a weekend or during a day when you can check on it periodically. Once completed, freeze portions in containers for future pho meals, making the process faster on subsequent occasions.
Rice noodles for pho come in different thicknesses, though the traditional choice is thin noodles about the width of spaghetti. These noodles are typically sold fresh, dried, or frozen at Asian grocery stores. Fresh noodles have a softer texture and cook in just 1 to 2 minutes of boiling water. Dried noodles take 4 to 5 minutes. Frozen noodles fall between the two options. For home pho, dried noodles are most practical because they store indefinitely and cook consistently.

To cook dried rice noodles, bring a large pot of water to a rolling boil. Add noodles and stir gently to prevent sticking. Cook for the time indicated on the package, usually 4 to 5 minutes, until the noodles are tender but still have slight firmness when bitten. Taste a noodle to check doneness—overcooked noodles become mushy and unpleasant.
Drain the cooked noodles in a colander and rinse briefly under warm water to remove excess starch. Some cooks rinse noodles in cold water to stop cooking, while others keep them warm. This is a matter of preference. If you rinse in cold water, you can reheat the noodles by placing them in a bowl and pouring hot broth over them.
Another approach is to cook noodles directly in the bowl. Place uncooked noodles in a serving bowl, pour hot broth over them, and let sit for 5 to 7 minutes until softened. This method reduces cookware and keeps noodles at the right temperature.
The quality of rice noodles varies significantly by brand and source. Vietnamese brands typically offer better texture and flavor than generic versions. Look for packages listing rice and water as the only ingredients. Some brands add tapioca starch or other additives, which can affect texture. Buying from stores with high turnover ensures fresher product.
Takeaway: Purchase dried rice noodles from Asian markets and store them in an airtight container away from moisture. Test different brands to find one you prefer, then buy in bulk. Having quality noodles on hand makes it quick to prepare pho once your broth is ready.
The protein in pho can be prepared in different ways depending on which type of pho you're making. For traditional beef pho (pho bo), the meat is partially cooked or served raw. Thinly sliced raw beef cooks quickly when placed in a bowl and covered with piping-hot broth. This method preserves the tender texture and delicate flavor of the meat.

To prepare raw beef for pho, purchase beef sirloin or beef tenderloin and partially freeze it for 1 to 2 hours. Partially frozen meat is easier to slice thinly. Use a sharp knife or ask your butcher to slice the meat for you. Slices should be thin enough to see through and approximately 1/8-inch thick. Arrange these slices on a plate and bring them to the table. Guests place the raw beef in their bowl, and the hot broth cooks it instantly.
Traditional pho bo also includes cooked beef brisket. To prepare brisket, place a 1.5 to 2-pound piece in the pot with the bones during the last 45 minutes to 1 hour of broth simmering. This cooks the meat while adding flavor to the broth. Once cooked, remove the brisket and allow it to cool. Slice it thinly against the grain and set aside until serving. The tender,
