Begin by preheating your oven to 400°F (200°C) to ensure it's ready for baking.
In a large oven-safe skillet, pour in the chicken or vegetable broth. Add the soy sauce, sesame oil, minced garlic, and grated ginger. Use a spoon to stir all the ingredients together until evenly mixed.
Place the skillet on medium heat and bring the broth mixture to a gentle simmer, letting the flavors meld for about 3-4 minutes.
Carefully introduce the frozen dumplings into the simmering broth. Ensure they are mostly submerged to absorb the flavors during cooking.
Evenly distribute the broccoli florets, shredded carrots, and shelled edamame over the dumplings. This layering helps ensure all ingredients cook evenly.
Transfer the skillet to the preheated oven and bake for 25-30 minutes. You want the dumplings to be fully cooked and the vegetables tender, so check for doneness around the 25-minute mark.
Once baked, carefully remove the skillet from the oven and allow it to cool slightly for a couple of minutes.
Just before serving, garnish the dish with thinly sliced green onions and a sprinkle of sesame seeds to enhance flavor and add a nice crunch.
Notes
Feel free to customize the vegetables based on your preference.
