Vietnamese Beef Phở (Pressure Cooker Method)
There are certain smells that don’t leave you.
For me, it’s beef bones gently simmering with toasted spices. Star anise. Charred onion. Ginger.
Growing up, weekends meant one thing: Dad had a pot of phở going before anyone else was awake.
Traditionally, beef phở takes anywhere between 6-24 hours — sometimes longer. And when I have the time, I still love doing it that way.
But here’s the truth: most of us don’t have all day.
That’s where the pressure cooker changes everything.
You still build the broth properly. You still toast the spices. You still char the aromatics. You still blanch the bones for clarity. The only difference is time — not flavor.
And if you do it right, you get a clear, golden, deeply beefy broth in under three hours.
This is how I make it.
Why the Pressure Cooker Works
Phở broth is about extraction — pulling collagen, marrow, and depth from bones slowly and cleanly.
A pressure cooker speeds up that extraction dramatically by increasing temperature and pressure, breaking down connective tissue faster while still preserving clarity.
The key is building the foundation correctly first.
Dad’s Pho Spice Kits
My dad’s phở spice kits are built the way we actually use them at home. You’re not just getting whole spices — you’re getting two spice bags for layering flavor (makes 2 separate pots of pho or one XL pot), plus the key seasonings most people forget: rock sugar, mushroom powder for depth, and a touch of MSG for that clean, savory finish.
Most of the spices are sourced from Vietnam, so when that broth starts steaming and hits your face, you get that familiar aroma — the one that instantly tells you this is real phở. It’s balanced, traditional, and designed to give you that clear, deeply fragrant broth without guessing.
Ingredients
For the Broth
2.5–3 pounds beef bones (use a mixture of knuckle bones, leg/marrow bones, and/or oxtail bones)
1 large white onion, charred
2 oz fresh ginger, sliced lengthwise and charred
1 sachet from Dad’s Spice Kit
6 small pieces of rock sugar from Dad’s Spice Kit (or granulated sugar)
3-4 tablespoons fish sauce from Dad’s Spice Kit
1/2 tbs kosher (adjust to taste) from Dad’s Spice Kit
1/2 tbs mushroom powder from Dad’s Spice Kit
Water (to max fill line of pressure cooker)
Noodles & Garnishes
Dried banh phở rice noodles (flat rice pho noodles)
Thinly sliced ribeye or beef petite tender (for rare beef)
Beef balls (optional)
Bean sprouts (optional)
Green onions
Cilantro
Lime wedges
Black Pepper
Sauces (served on the side)
Hoisin
Sriracha
Step-by-Step Instructions
1. Toast the Spices
In a dry pan over low to medium heat, smash black cardamon pods, then toast your spice sachet for 2–3 minutes until fragrant. Set aside.
This wakes up the oils in the spices and deepens the aroma.
2. Char the Aromatics
Place the halved onion and ginger cut-side down in a dry pan or directly over flame. Char until deeply browned and fragrant and rinse off any burnt loose burnt pieces. Set aside.
The char adds depth and subtle smokiness — this is essential.
3. Blanch the Bones
Place beef bones in a pot, cover with water, and boil for 5 minutes. Drain and rinse the bones thoroughly under cold water. Discard the blanching liquid.
This removes impurities and helps achieve a clear broth.
4. First Pressure Cycle
Add to the pressure cooker:
Blanched bones
Beef brisket or shank
Charred onion and ginger
Rock Sugar
Mushroom Powder
Fill with water to the maximum fill line. Seal and set to pressure cook for 1 hour.
Depending on your pressure cooker you may need to do a natural release for 15 minutes before venting.
5. Second Pressure Cycle (Building Depth)
Open the lid. Remove tendons and aromatics (this prevents it from overcooking).
Seal again and pressure cook the bones for another 1 hour.
Natural release again.
This layered pressure method builds depth while keeping the broth clean.
6. Strain and Season
Remove all bones and solids.
Strain the broth thoroughly through a fine mesh strainer or cheesecloth.
Return broth to the pot and fill with water again if needed to reach desired volume.
Add:
3-4 tablespoons fish sauce
Salt to taste
Optional MSG to taste
1 Spice sachet
Taste and adjust seasoning. The broth should be clear, savory, slightly sweet, and balanced.
Switch to sauté, or simmer or stew mode and let it gently simmer for 30 minutes.
Preparing the Rare Beef
For paper-thin slices at home:
Place ribeye or petite tender in the freezer for 1-2 hours until partially firm/frozen.
Slice thin using a sharp knife or mandoline.
Assembling the Bowl
Cook rice noodles according to package instructions.
Add noodles to a bowl.
Top with sliced raw thin beef
Pour boiling broth over everything.
Finish with green onions, cilantro, bean sprouts, and lime.
Serve hoisin and sriracha on the side.
