Preheat Oven:Preheat your oven to 350°F (175°C).
Sauté the Corn:In a large skillet over medium heat, melt the butter. Add frozen corn and cook until softened, about 5–7 minutes.
Make It Creamy:Stir in the cubed cream cheese and cook, stirring frequently, until the cheese has melted and combined with the corn.
Add the Flavor:Sprinkle in the ranch seasoning and stir in the chopped bacon. Mix well to distribute everything evenly.
Cheese It Up:Remove the skillet from heat and stir in 1 cup of shredded cheddar Jack cheese.
Bake the Casserole:Transfer the mixture to a greased baking dish. Top with the remaining 1 cup of cheese.
Bake Until Bubbly:Bake uncovered for 20–30 minutes, or until the top is golden, melted, and bubbly.
