Prep the cauliflower rice: If using fresh cauliflower, pulse florets in a food processor until rice-sized. Set aside.
Heat the pan: Add avocado oil to a large skillet over medium-high heat.
When hot, add the ground beef and break it up with a spatula.
Brown the beef: Cook until the beef is mostly browned with some crispy edges, 5–7 minutes. If there’s excess grease, drain a bit, but leave some for flavor.
Add aromatics: Stir in garlic and ginger. Cook 30–60 seconds until fragrant, stirring so they don’t burn.
Make the sauce: Reduce heat to medium.
Add tamari or coconut aminos, sesame oil, low-carb sweetener, gochugaru, vinegar, and black pepper. Stir to coat the beef evenly.
Simmer and thicken: Let the beef bubble gently for 2–3 minutes. The sauce should cling to the meat.
Taste and adjust sweetener, heat, or salt if needed.
Cook the cauliflower rice: In a separate skillet, melt butter over medium heat. Add cauliflower rice and a pinch of salt. Sauté 4–5 minutes until tender but not mushy.
Assemble the bowls: Divide cauliflower rice into bowls.
Top with Korean beef, sliced cucumber or cabbage, and green onions.
Finish with toppings: Sprinkle sesame seeds. Add extras like a fried egg, nori strips, or a squeeze of lime if you like.
Serve hot: Enjoy immediately while it’s steamy and fragrant.
