In a medium mixing bowl, combine the fish sauce, tamari, brown coconut sugar, and Chinese five-spice powder. Then add the beef stew meat and ensure it’s all evenly coated.
Set the Instant Pot to Saute mode and sear the beef stew meat until it’s brown, for about 2 to 3 minutes on each side. After you’re done searing, remove it from the Instant Pot and set it aside. Don’t worry about it not being fully cooked at this time.
Next, add the shallots and garlic. Saute for 1 to 2 minutes until the shallots have softened. Finally, add the remaining aromatics: cinnamon stick, star anise, ginger, and lemongrass.
Lastly, add your carrots, seared stew meat, beef bone broth, fish sauce, and tomato paste. Set the Instant Pot to Pressure Cook (or Manual) for 20 minutes and ensure the sealing knob is set to seal.
After the Instant Pot beeps, allow it to naturally release (which should take about 20 more minutes).
Garnish with your toppings of choice and serve with rice stick noodles.
