Preheat your oven to 375°F.
Place the pie crust into a pie pan, ensuring the edges are nicely crimped.
Scatter crab meat, green onions, and red bell pepper evenly over the crust base.
Sprinkle the shredded cheddar cheese on top.
In a mixing bowl, whisk together the eggs, heavy cream, milk, salt, and black pepper until well combined.
Pour the egg mixture gently over the ingredients in the crust.
Place the filled pie crust on a baking sheet and put it into the preheated oven.
Bake for about 35 to 40 minutes, or until the custard is set and the top is golden brown.
Remove from the oven and let it cool for about 15 minutes before slicing.
