Preheat the oven to 375 degrees Fahrenheit.
Peel and dice the red onion, garlic cloves, and ginger.
Add oil to a heavy bottom pan and then add in the diced onion, ginger, and garlic. Sauté about 5 minutes, stirring often, so the threesome does not burn.
Add in the frozen beans (they do not need to be thawed).
Add in the coriander, smoked paprika, turmeric, and cinnamon and stir well.
Then add in the coconut milk and stir well.
Season with salt and pepper to taste and stir well.
Turn the stove off. Carefully transfer this green bean mixture to an oven-safe dish.
Sprinkle the fried onions on top.
Place the green bean casserole in the preheated oven and bake for 15 minutes at 375 degrees.
Remove from the oven. Sprinkle with some chopped parsley (though this is totally optional).
Enjoy!
