Korean-Style Gochujang Flank Steak with Bok Choy & Sautéed Mushrooms
Korean-inspired comfort without a long marinade: flank steak gets a fast gochujang-soy glaze, then it’s sliced over a hot skillet of garlicky bok choy and mushrooms. Big flavor, lots of veggies, and it hits that ‘takeout at home’ sweet spot.

Instructions
- Prep steak & sauce: Pat 1 lb flank steak dry. In a bowl, whisk 3 Tbsp soy sauce, 1 1/2 Tbsp gochujang, 1 Tbsp honey (or brown sugar), 1 Tbsp rice vinegar (or lemon juice), 1 Tbsp grated ginger, and 1 tsp diced garlic. Spoon 2 Tbsp of this sauce into a small cup and set aside for finishing; use the rest to coat the steak. Let sit 10 minutes while you prep vegetables.
- Prep vegetables: Halve 1 lb baby bok choy lengthwise. Slice 8 oz mushrooms. Thinly slice 2 green onions (keep some green tops for garnish).
- Sear steak (stove): Heat 1 Tbsp neutral oil in a large skillet or grill pan over medium-high heat. Sear the flank steak 3–5 minutes per side (depending on thickness) for medium-rare to medium. Transfer to a plate and rest 8–10 minutes.
- Stir-fry mushrooms: In the same skillet, add 1 Tbsp neutral oil. Add mushrooms with a pinch of salt and cook until browned and their moisture evaporates, 5–7 minutes.
- Cook bok choy: Add bok choy cut-side down and cook 2 minutes. Add 1 tsp diced garlic plus 2 Tbsp water, cover, and steam 2–3 minutes until crisp-tender. Uncover and toss everything together; season with black pepper.
- Glaze & slice: Slice the rested flank steak thinly against the grain. Return sliced steak to the pan briefly and drizzle in the reserved 2 Tbsp sauce; toss 30 seconds just to coat and warm (don’t overcook).
- Serve: Spoon mushrooms and bok choy into bowls (add 1 cup cooked rice for 2 if using). Top with sliced steak, scatter green onions, and finish with sesame seeds if you like.

Health notes: Approx per serving: ~650–850 calories depending on steak portion and rice/no-rice. High protein; bok choy is rich in vitamin C/K. Keep sodium in check by using low-sodium soy and adding extra lime/lemon juice for brightness.
Drink pairing: Spicy-sweet gochujang loves aromatic whites: off-dry Riesling-style tames heat and amplifies the glaze. For red, go low-tannin and juicy—Gamay-style (Beaujolais) keeps it bright without fighting the spice. If you want something crisp and savory, Grüner Veltliner-style handles garlic and umami beautifully.
