Start by dicing the yellow onion and chopping the green onions. Set them aside for later use.
In a large skillet over medium heat, add the ground turkey. Cook until it’s browned, breaking it apart with a wooden spoon as it cooks. This should take about 5-7 minutes.
Once the turkey is browned, add the finely diced yellow onion to the skillet. Stir well and cook until the onions are translucent, around 3-4 minutes.
Sprinkle in salt, pepper, dried ginger, garlic powder, and ground coriander. Stir to combine, allowing the spices to coat the turkey and onion mixture evenly.
Pour in the soy sauce, brown sugar, beef broth, sweet chili sauce, and Worcestershire sauce. Stir everything together until the turkey is well-coated with the sauce, and let it simmer for about 5 minutes, allowing the flavors to meld.
Drizzle in the sesame oil and add sriracha to taste, stirring until everything is well combined. This step adds a beautiful richness to the dish and a kick of spice.
Remove the skillet from heat. Serve the Korean beef over rice or lettuce wraps and garnish with chopped green onions. For a fresh crunch, add some sliced carrots, cucumbers, or radishes on the side.
