Wash the zucchinis and slice them in half lengthwise. Use a spoon to scoop out the seeds, creating a boat shape.
Place the zucchini halves on a baking sheet and drizzle with olive oil. Sprinkle with salt and pepper. Bake in the preheated oven for 10 minutes to soften slightly.
In a mixing bowl, combine the shredded chicken, buffalo sauce, cream cheese, half of the cheddar cheese, and chopped green onions. Mix until well incorporated.
Remove the zucchini from the oven and carefully fill each half with the buffalo chicken mixture.
Top each stuffed zucchini with the remaining cheddar cheese.
Return the baking sheet to the oven and bake for an additional 15-20 minutes, or until the cheese is bubbly and golden.
Remove from the oven and let cool for a few minutes. Garnish with fresh parsley before serving.
Notes
Adjust the buffalo sauce to your spice preference.
