Phở Bò Viên (Vietnamese Beef Noodle Soup with Homemade Meatballs)

When you think of Vietnamese food, you think of phở. And one of the simplest phở to make, and a favorite among Vietnamese children, is phở bò viên.

It’s warm, filling and easy to eat. It’s perfect for a cold winter day or when you need something comforting to soothe the soul.

In this recipe, I’ll show you how to make a flavorful phở beef broth using just one type of bone and bouncy beef meatballs made completely from scratch.

What is Pho Bo Vien?

If you go to a Vietnamese restaurant, you might see an expansive phở menu that goes on for miles. Have no fear—it’s only long because of the many different variations you can order.

The base is all the same: a hearty beef stock. It’s the toppings that change. The one type of phở my kids absolutely loved, especially when they were little, was always phở bò viên.

Phở bò viên is a variation of phở that simply pairs springy beef meatballs with rice noodles in a clear broth, finished with fresh garnishes like green onions and cilantro, which the kids usually ask to leave out.

These meatballs are bouncy, savory, and lightly seasoned. You can get this already made at Asian grocery stores, but you can also make them from scratch, and that is exactly what we’re doing in this recipe.

What You Will Need

For the Beef Broth

• Beef bones: Unlike my traditional phở bò recipe that calls for multiple types of bones, I’m using just one to keep this simple. Look for bones labeled beef soup bones in clear bags in the freezer aisle at Asian markets. These cuts usually contain marrow bones, which add plenty of rich flavor to the broth.
• Aromatics: A large yellow onion (or shallots) and fresh ginger. Toasting or charring them lightly first unlocks their aroma and helps build layers of deep flavor.
• Pho spices: Instead of gathering individual spices, I’m using a phở spice packet that you can quickly grab at any Vietnamese or Asian grocery store. They contain everything you need in one small bag. These include star anise, cassia cinnamon, cloves, coriander seeds, cardamom, and fennel. These packets are incredibly helpful because they not only hold the perfect blend of spices, but they usually include a small cotton bag for steeping them directly in the broth.
• Broth seasonings: Fine ground sea salt, good-quality fish sauce, granulated sugar (or rock sugar), and MSG (optional, but highly recommended for authentic restaurant-level savoriness).

For the Beef Meatballs (Bò Viên)

• Ground beef:80% to 90% lean ground beef. Freeze it partially in thin sheets so you can blend or whip it into a fine paste without the friction heating up and cooking the meat.
• Aromatics & seasonings: Finely minced garlic, minced shallots, fish sauce, sugar, salt, black pepper, and optional MSG.
• Texture builders: Baking powder to create the light and bouncy texture that is signature to Vietnamese beef meatballs for pho and cornstarch or tapioca starch and a splash of ice-cold water for binding.

For Serving & Assembly

• Pho noodles (bánh phở): Dried flat rice noodles because they are pantry stable and very convenient. You can also use fresh flat rice noodles if preferred.
• Garnishes: Roughly chopped cilantro and thinly sliced green onions.
• Table condiments: Fresh lime wedges, pickled chili peppers, hoisin sauce, and Sriracha for dipping.

How to Get Clear Pho Broth

• Parboiling: For a restaurant-quality, clear broth, parboiling is your best bet. A quick boil draws out coagulated blood and impurities so you can rinse them away before simmering. If you prefer a richer, beefier flavor, you can skip parboiling and simply soak the raw bones in hot water for 30 minutes. Just keep in mind that soaking yields a slightly darker, amber broth and requires more frequent skimming during the first hour.
• Gentle simmer: Never let your stock roll at a vigorous boil. High heat churns and emulsifies the rendered fat and bone sediment back into the water, resulting in a cloudy broth. Keep the heat low.

FAQs

Do I have to char the onion and ginger?

It isn’t mandatory, but charring caramelizes the natural sugars and lends the broth its signature smoky aroma and subtle sweetness. If you are short on time, tossing them in raw works too, but taking 10 minutes in the air fryer or toaster oven makes a noticeable difference.

Can I make this in an Instant Pot or pressure cooker?

Yes! I have a specific recipe for Instant Pot pho if you prefer using a pressure cooker.

Why are Vietnamese beef meatballs bouncy?

Unlike Italian meatballs, which use coarse ground meat, binders, and breadcrumbs for a soft, tender bite, Vietnamese bò viên rely on emulsification. Whipping very cold, partially frozen beef into a fine paste develops the meat protein (myosin). Combined with baking powder and starch, this process creates that springy, elastic texture with a distinct snap.

Storage & Reheating

Refrigerator: Store leftover broth and meatballs together in an airtight container or in the covered pot in the fridge for up to 3 days. Always store cooked rice noodles and fresh herb garnishes in separate containers so the noodles don’t soak up all the soup.

Reheating: Bring the broth and meatballs to a rolling boil on the stovetop. I usually place the cold noodles in a serving bowl and reheat them in the microwave than ladle hot broth over them.
