Beef and Broccoli AF1: Easy Skillet Recipe

Beef and broccoli AF1 is a quick skillet-style take on the familiar Chinese American combination of tender beef, crisp broccoli, and savory sauce. Thinly sliced steak cooks fast, while a simple soy, ginger, and garlic sauce brings everything together for serving over rice; regional and household versions vary, and this recipe keeps the ingredients practical.

Ingredients

1 lb (450 g) flank steak, trimmed and sliced thinly across the grain
1 lb (450 g) broccoli florets, cut into bite-size pieces
3 tbsp (45 ml) low-sodium soy sauce, divided
1 tbsp (15 ml) Shaoxing wine or dry sherry, optional
1 tbsp (8 g) cornstarch, divided
½ cup (120 ml) low-sodium beef broth or water
1 tbsp (15 ml) oyster sauce
1 tsp (5 ml) toasted sesame oil
1 tsp (5 g) granulated sugar
2 tbsp (30 ml) neutral cooking oil, divided
3 garlic cloves (about 9 g), finely chopped
1 tbsp (6 g) finely grated fresh ginger
¼ tsp red pepper flakes, optional
2 scallions (about 30 g), thinly sliced, for serving
Cooked rice, for serving (about 4 cups / 600 g cooked)

Instructions

Slice the steak across the grain into strips about ¼ inch (6 mm) thick. In a bowl, toss it with 1 tablespoon (15 ml) soy sauce, the Shaoxing wine if using, and 2 teaspoons (about 5 g) cornstarch. Set aside for 10 minutes while you prepare the remaining ingredients. Keep raw beef and its utensils separate from ready-to-eat foods.
Whisk the broth, remaining 2 tablespoons (30 ml) soy sauce, oyster sauce, sesame oil, sugar, and remaining 1 teaspoon (about 3 g) cornstarch in a small bowl until smooth. Have the sauce beside the stove before cooking; stir it again just before adding, as cornstarch settles.
Bring a large pot of water to a boil. Add the broccoli and cook for 2 minutes, until bright green and just beginning to soften. Drain well. Alternatively, steam the broccoli for 3–4 minutes. Avoid cooking it until fully tender now, because it will warm further in the skillet.
Heat a large skillet or wok over high heat until hot. Add 1 tablespoon (15 ml) neutral oil, then spread the beef in a single layer, working in batches if the pan is crowded. Sear for about 1–2 minutes per side, just until browned; transfer to a clean plate. For food safety, check the thickest pieces with a food thermometer: USDA FSIS lists 145°F (63°C) with a 3-minute rest as the safe minimum for whole cuts of beef. Sliced steak can be difficult to check individually; keep the pieces together long enough to verify temperature, and return under-temperature beef to the pan to finish cooking.
Reduce the heat to medium-high and add the remaining 1 tablespoon (15 ml) oil. Add the garlic, ginger, and pepper flakes, if using; stir for about 20 seconds, just until fragrant. Do not let the garlic brown, which can make it bitter.
Add the drained broccoli and pour in the sauce. Stir and toss for 1–2 minutes, until the sauce bubbles and thickens enough to coat the broccoli. Return the beef and any juices to the pan and toss for about 1 minute, until hot throughout. If the sauce is too thick, loosen it with a tablespoon or two of water; if it is thin, simmer briefly while stirring.
Remove from the heat, scatter the scallions over the top, and serve promptly with cooked rice.

Tips

Slice across the grain. Look for the direction of the long muscle fibers and cut across them; this shortens the fibers and makes flank steak easier to chew. Partially freezing the steak for 15–20 minutes can make thin slicing easier, but that optional wait is not included in the recipe timing.
Keep the pan uncrowded. If steak strips overlap, they release moisture and steam instead of browning. Cook in two batches, letting the pan get hot again between batches.
Use the suggested swaps carefully. Dry sherry can replace Shaoxing wine. If oyster sauce is unavailable, use hoisin sauce for a sweeter, more strongly seasoned result, or add another teaspoon of soy sauce for a less rounded sauce. Check labels if avoiding shellfish or gluten.
Measure sauce before the pan gets busy. Cornstarch thickens quickly once heated, and pre-mixing the sauce helps prevent lumps. Choose low-sodium broth and soy sauce if you want better control over saltiness.

Serving Suggestions

Serve the beef and broccoli over steamed long-grain or jasmine rice, with extra sauce spooned over the rice. Brown rice, noodles, or cauliflower rice also work. A side of cucumber salad, sautéed greens, or simple steamed dumplings makes the meal more substantial without competing with the savory sauce. For extra crunch, add sesame seeds at the table.

Variations

Swap flank steak for sirloin or skirt steak, slicing it thinly across the grain; tender cuts such as these cook quickly and suit the short stir-fry method. For a meat-free version, replace the beef with firm tofu, pressed and cubed, and use vegetable broth; brown the tofu before cooking the aromatics. Add sliced red bell pepper or mushrooms with the broccoli, keeping the total vegetables near 1½ lb (680 g) so the sauce still coats them. For more heat, increase the pepper flakes or serve chili crisp on the side.

Storage and Reheating

Refrigerate leftovers within 2 hours of cooking in a shallow, airtight container. They keep for 3–4 days in the refrigerator. Freeze in a sealed freezer-safe container for up to 2–3 months for best quality; thaw overnight in the refrigerator. Reheat only the portion you plan to eat in a skillet with a splash of water, stirring until steaming hot, or microwave it in a covered, microwave-safe dish, stirring partway through. Leftovers should reach 165°F (74°C) when checked with a food thermometer. Broccoli softens after storage, but the flavor remains good.

Frequently Asked Questions

What does “AF1” mean in beef and broccoli AF1?
The phrase appears to be a search or recipe label rather than a standard cooking term or established style of beef and broccoli. This recipe describes the dish itself: beef and broccoli tossed with a soy-based skillet sauce.

What is the best beef for beef and broccoli?
Flank steak is a reliable choice because it is easy to slice thinly and cooks quickly. Sirloin and skirt steak also work. In every case, cut across the grain and avoid overcrowding the pan.

Can I make the sauce without oyster sauce?
Yes. Hoisin is an accessible substitute, but it is sweeter and thicker, so start with a little less sugar and add water if needed. For a more savory, less sweet result, use an extra teaspoon of soy sauce instead; the sauce will be less rich.

Can I use frozen broccoli?
Yes. Thaw it and drain it well first, then skip the blanching step. Add it to the skillet long enough to heat through; excess water can dilute the sauce, so pat it dry if it seems wet.

How do I keep the beef tender?
Slice across the grain, keep the strips thin and uniform, and sear them briefly in a hot, uncrowded pan. Return the beef to the skillet only near the end so it does not simmer for several minutes in the sauce.

Can I prepare parts of this recipe ahead?
You can slice the vegetables and mix the sauce up to a day ahead, storing them covered in the refrigerator. For best texture, slice and season the beef shortly before cooking; keep it chilled until it goes into the hot pan.
