Preheat your oven to 400°F (200°C).
In a baking dish, whisk together the coconut milk, Thai red curry paste, minced garlic, soy sauce, lime juice, and sesame oil until smooth.
Stir the spinach into the sauce and spread evenly across the dish.
Arrange the frozen dumplings in a single layer over the spinach mixture.
Bake uncovered for 30–35 minutes, or until the dumplings are crispy on top and the sauce is bubbling around the edges.
For extra crispiness, broil for 2–3 minutes at the end of cooking time.
Remove from the oven and garnish with chopped cilantro, scallion greens, sesame seeds, and chili crisp.
Serve the easy crispy chili oil dumplings hot with extra lime wedges if desired.
