Crispy Mandarin Chili Beef Shreds Step-by-step instructions

Before you start

Before starting, set up all the ingredients and equipment. Slice the sirloin into thin matchsticks and place in a large bowl. Whisk the egg white in a small bowl until frothy. Measure the potato starch into a separate bowl.

In another small bowl, combine the Mandarin juice, sweet chili sauce, and soy sauce; stir until uniform. Mince the ginger and garlic. Julienne the carrot and toast the sesame seeds if not already toasted. Line a wire rack with paper towels and have tongs and a deep-fry thermometer ready.

Instructions

Prep and Coat

1. 1Prep the beef and glaze
   Slice the sirloin against the grain into thin matchsticks, about 2 inches long. In a large bowl, toss the beef with the egg white until evenly coated. Add the potato starch and toss thoroughly so every shred is lightly dusted; the coating should look dry and powdery. In a small bowl, whisk the Mandarin juice, sweet chili sauce, and soy sauce until smooth. Set the glaze aside.
   Look for The beef shreds are separate and evenly coated with a dry, powdery starch layer.
   Tip Work in batches if needed to keep the coating light; clumps will fry unevenly.
2. 2Heat the frying oil
   Pour the vegetable oil into a large wok or Dutch oven and attach a deep-fry thermometer. Heat over medium-high until the oil reaches 390°F (199°C). While the oil heats, line a wire rack with paper towels and set it near the stove.
   Look for The oil shimmers and a small piece of beef sizzles immediately when dropped in.
   Tip Maintain the temperature between 375°F and 390°F while frying; adjust the heat as needed.

The beef matchsticks are evenly coated with a dry, powdery starch layer. The glaze is smooth and aromatic, with a bright citrus scent and a hint of chili. The oil is heating and shimmering. Everything is ready for frying—this is the calm before the sizzle.

Fry and Glaze

3. 3Fry the beef in batches
   Carefully add about one-third of the beef matchsticks to the hot oil, using tongs to separate them as they hit the oil. Fry for 2 minutes, turning occasionally, until deep golden brown and crunchy like straws. Transfer to the prepared wire rack. Repeat with the remaining beef, letting the oil return to 390°F between batches. Let it rest for 3 minutes before slicing.
   Look for The beef is deeply browned, crisp, and makes a crackling sound when squeezed.
   Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
   Tip Do not overcrowd the pan; frying in small batches keeps the oil temperature steady.
4. 4Stir-fry aromatics and glaze
   Carefully pour off all but 2 tablespoons of the oil from the wok. Return the wok to high heat until the oil shimmers. Add the ginger and garlic, and stir-fry for 15 seconds until fragrant. Pour in the Mandarin glaze and let it bubble and reduce for about 1 minute, until it thickens to a syrupy consistency and coats the back of a spoon.
   Look for The glaze is glossy, thick, and smells intensely sweet and spicy.
   Tip Keep the heat high to reduce quickly; do not let the garlic burn.
5. 5Toss beef in the glaze
   Add the fried beef shreds to the wok and toss constantly with tongs for 30 seconds, until every piece is coated in the sticky glaze. The beef should remain crisp; the glaze will cling and form a crackly, translucent coating. Remove the wok from the heat immediately. Let it rest for 3 minutes before slicing.
   Look for The beef is glossy, with a translucent, crackly coating that shatters when bitten.
   Safe temperature 160°F (71°C) internal temperature (egg dishes)
   Tip Toss quickly to avoid softening the crisp coating; the residual heat finishes the glaze.

The kitchen fills with the rich scent of frying beef. The shreds turn deep golden brown and crisp, making a crackling sound when squeezed.

The glaze bubbles and thickens into a glossy syrup. After tossing, each piece is coated in a shiny, translucent layer that shatters with a satisfying crunch.

Rest and Serve

6. 6Rest and serve
   Let the beef rest on the wire rack or in the wok for at least 3 minutes before serving; this allows the coating to set and the meat to rest. Transfer to a serving platter and top with julienned carrot and toasted sesame seeds. Serve immediately while the beef is still crunchy.
   Look for The beef is shiny, crisp, and topped with bright carrot and sesame.
   Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
   Tip Resting is essential for the coating to firm up; do not skip this step.

The beef rests, allowing the glaze to set into a crackly coating. The platter is topped with bright carrot and sesame seeds. The dish looks glossy and inviting, with a perfect balance of colors and textures. Serve immediately to enjoy the crunch at its peak.

Common mistakes

A common mistake is overcrowding the pan when frying, which drops the oil temperature and leads to soggy, greasy beef. Fry in small batches and let the oil return to 390°F between batches. Another pitfall is skipping the egg white; it helps the starch adhere and creates a more even coating.

If the glaze is too thin, it will slide off the beef; reduce it longer until it is syrupy. Finally, tossing the beef for too long in the glaze will soften the crust; toss quickly and serve immediately.

How to tell it’s done

The beef is done when it reaches an internal temperature of 145°F (63°C) and is deeply golden brown and crunchy. The glaze is ready when it has reduced to a syrupy consistency that coats the back of a spoon.

After tossing, the beef should be glossy and the coating crackly. Let the beef rest for at least 3 minutes before serving, which allows the coating to set and the juices to redistribute. The final dish should be crisp, sweet, spicy, and utterly irresistible.

• Steaks, chops and roasts: 145°F (63°C) in the thickest part, then a 3-minute rest
• Egg dishes: 160°F (71°C) in the thickest part
