Step 1: Make the Coconut Sauce Whisk together coconut milk powder and warm water until smooth. Add soy sauce, brown sugar, chili crisp, sesame oil, garlic, ginger, and fish sauce. The sauce should be creamy, lightly sweet, and a little spicy.
Step 2: Assemble the Bake Add chopped bok choy to the bottom of a medium baking dish.Place frozen dumplings on top — no need to thaw.Pour the sauce all over, making sure the tops get coated.
Step 3: Bake
Bake at 400°F for 25–30 minutes until bubbling and the tops look lightly golden.If you accidentally bake at 350°F (it happens!), just raise the heat and continue baking until the tops are tender and the sauce thickens.
Step 4: Crisp the Top (Optional) If you'd like crispy peaks, broil for 1–2 minutes. Watch carefully — dumplings brown fast.
Step 5: Garnish and Serve Finish with scallions, sesame seeds, and extra chili crisp.Serve as-is, or spoon over rice or noodles.
