Hunan Cumin Beef Stir-Fry

Ingredients

• 1.25 lbs Flank steak or sirloin, thinly sliced against the grain
• 3 tablespoons Low-sodium soy sauce
• 2 tablespoons Rice vinegar
• 1 tablespoon Sesame oil
• 1 tablespoon Cornstarch
• 2 teaspoons Cumin seeds
• ½ teaspoon Sichuan peppercorns
• 4 whole Dried red Hunan chilies, stems removed
• 3 tablespoons Vegetable oil
• 4 whole Garlic cloves, peeled
• 1 piece Fresh ginger, 1-inch piece
• 3 whole Green onions, cut into 1-inch pieces
• ½ cup Water
• ½ teaspoon Sugar
• 1 pinch Kosher salt, to taste

Instructions

1. 1

   Slice 1.25 lbs of flank steak or sirloin against the grain into 1/8-inch-thick strips — cutting against the grain ensures the beef stays tender and doesn't become stringy when you stir-fry it. Spread the strips on a plate.

2. 2

   In a small bowl, whisk together 3 tablespoons of low-sodium soy sauce, 2 tablespoons of rice vinegar, 1 tablespoon of sesame oil, and 0.5 teaspoon of sugar. Set the sauce bowl beside your stovetop — you'll need it ready during cooking.

3. 3

   In another small bowl, combine 1 tablespoon of cornstarch with 0.5 cup of water and stir until smooth. This slurry will thicken the sauce and coat the beef. Set aside.

4. 4

   Toast 2 teaspoons of cumin seeds and 0.5 teaspoon of Sichuan peppercorns in a dry 12-inch wok or skillet over medium heat for 1-2 minutes, shaking gently, until fragrant and slightly darker. Transfer to a small bowl and crush lightly with the bottom of a spoon — you want some texture, not a powder.

5. 5

   Finely mince 4 garlic cloves and grate the 1-inch piece of fresh ginger on a microplane. Snip 4 dried red Hunan chilies in half lengthwise with kitchen shears to release their heat, keeping the seeds inside for maximum flavor.

6. 6

   Cut 3 green onions into 1-inch pieces, separating the white and light-green parts from the darker green tops — the lighter parts will cook with the beef, and the darker tops will garnish at the end.

7. 7

   Set your 12-inch wok or skillet over high heat and let it preheat for 2 minutes until a drop of water dances on contact. This high heat is essential — it will sear the beef quickly and give it a golden crust.

8. 8

   Pour 1.5 tablespoons of vegetable oil into the hot wok and wait 20 seconds for it to shimmer and smoke slightly. Add half of the beef strips in a single layer without stirring — let them sear undisturbed for 1-2 minutes until deeply browned and caramelized on the bottom. Flip and cook the other side for another 1-2 minutes. Transfer this batch to a clean plate and repeat with the remaining 1.5 tablespoons of oil and remaining beef. The beef will still be rare — this is intentional, as it will continue cooking when everything comes back together.

9. 9

   Reduce heat to medium-high. Add the minced garlic, grated ginger, and halved Hunan chilies to the empty wok. Stir constantly for 30 seconds — you should smell the aromatics bloom and deepen. The chilies will begin to darken slightly.

10. 10

    Stir in the toasted, crushed cumin and Sichuan pepper blend. Cook for 15 seconds, stirring constantly, until the spices coat the aromatics and release their fragrant oils.

11. 11

    Pour the sauce bowl (soy mixture) into the wok and immediately add the cornstarch slurry, stirring constantly. The sauce should thicken within 30-45 seconds and turn glossy and translucent — you should see no white, cloudy cornstarch remaining.

12. 12

    Return all the seared beef to the wok along with the light-green and white parts of the green onions. Toss everything together for 1-2 minutes, gently folding the beef into the sauce to coat evenly. The residual heat will finish cooking the beef to medium-rare, bringing it to a safe internal temperature while keeping it tender.

13. 13

    Taste a spoonful of the sauce and adjust seasoning with kosher salt as needed — Hunan food should be bold and assertive, so don't be shy.

14. 14

    Transfer the stir-fry to a serving plate or bowl. Scatter the reserved dark-green tops of the green onions over the top for a fresh garnish and visual pop. Serve immediately over steamed white rice or with rice noodles — the sauce is thin and meant to pour over your grain.
