Cook the rice. Rinse rice until the water runs mostly clear. Cook according to package directions. Keep warm.
Warm rice is key to a cozy, satisfying bowl.
Prep the sauce. In a small bowl, whisk gochujang, tamari, sesame oil, rice vinegar, sweetener, and garlic. Add a splash of water to reach a drizzleable consistency. Taste and adjust: more vinegar for brightness, more sweetener to balance heat.
Marinate your protein (if using). Toss beef or tofu with tamari, sesame oil, honey, garlic, and pepper.
Let sit 10–15 minutes while you cook the vegetables.
Sauté the mushrooms. Heat a little neutral oil in a large skillet over medium-high. Add mushrooms with a pinch of salt. Cook until browned and tender, 4–6 minutes.
Finish with a few drops of sesame oil. Set aside.
Cook the carrots and zucchini. In the same pan, add a touch more oil. Sauté carrots with a pinch of salt until crisp-tender, about 2 minutes.
Remove. Repeat with zucchini, 2–3 minutes. Keep both slightly snappy for good texture.
Wilt the spinach. Add spinach to the hot pan with a drizzle of oil and a pinch of salt.
Toss until just wilted, 30–60 seconds. Set aside.
Bean sprouts. Quickly sauté or blanch the sprouts for 1 minute, then season with a tiny bit of sesame oil and salt. Keep them crunchy.
Cook the protein. For beef: Sear in a hot pan 1–2 minutes per side until just cooked and caramelized.
For tofu: Pan-fry until golden on all sides, 6–8 minutes total. For mushrooms-as-protein: Sear an extra batch to make it hearty.
Fry the eggs. Heat a little oil in a nonstick pan. Fry eggs sunny-side up until the whites set and the yolk stays runny.
A jammy yolk acts like rich sauce when mixed in.
Assemble. Add warm rice to bowls. Neatly arrange carrots, zucchini, spinach, sprouts, mushrooms, cucumber, and kimchi around the edges. Place your protein in the center and top with an egg.
Spoon on the gochujang sauce. Finish with sesame seeds and sliced green onions.
Mix and enjoy. At the table, stir everything together so the sauce and yolk coat the rice and veggies. Add more sauce if you like extra heat.
