Toss beef strips with 2 teaspoon soy sauce and 2 tablespoons of cornstarch; set aside.
To make the sauce, combine soy sauce, honey, sweet chili sauce, rice vinegar, garlic, and starch in a small mixing bowl; mix well and set aside.
Coat the beef again with the remaining cornstarch to ensure it is thoroughly coated.
Heat oil in a skillet over medium high heat until hot (about 350˚F, 170˚C). Add a small batch of beef strips, shaking off the excess starch, and shallow fry until lightly golden; about 1-2 minutes. Remove the beef strips using a metal wire strainer and place on a wired rack or a plate lined with a paper towel. Repeat with the next batch.
Note: If you put too many beef strips at once, they might stick to each other and you will end up with a giant ball of meat instead of small bite-sized strips. Doing small batches is key for a successful deep fry for this recipe.
Once the first-fry is completed, do the second-fry (again in small batches) until the beef turns deep brown and crispy, about 1 minute. Strain the beef with a metal strainer and transfer onto a wired rack.
Wipe the extra oil off the skillet, leaving about 1 tablespoon behind. Add shredded carrot and stir-fry for 1 minute until slightly soft. Add green onion and chili (if using) and stir for 10 seconds.
Pour the reserved sauce mixture in a skillet. It should bubble right away. When the sauce is reduced and thickened to a sticky glaze (about 5-10 seconds), return the beef strips and toss together to coat evenly.
Garnish with toasted sesame seeds if you wish. Serve the crispy beef immediately with rice.

Notes
Beef Cuts & Variations
If using skirt steak or a tougher cut, slice it thinly like shredded beef for a more tender texture. Thick slices can turn chewy, while thinner strips cook faster and stay tender.
Want variety? Swap the beef for chicken or pork—it works just as well!
How to Store & Reheat Crispy Beef
Storage: Let the beef cool completely, then store it in an airtight container in the fridge for up to 3 days. For longer storage, freeze it for up to 2 months.
Reheating: To keep it crispy, reheat in an air fryer (350°F for 3-5 minutes) or in a hot skillet over medium heat. Avoid microwaving, as it can make the beef soggy. If needed, add a splash of water to loosen the sauce.
