  1. Preheat your oven to 375°F (190°C) and grease a 9×13 inch baking dish with butter or cooking spray.
  2. In a large skillet, melt the butter over medium heat. Add the diced onions, red bell peppers, green bell peppers, and minced garlic. Cook until the vegetables are softened, about 5-7 minutes. Remove from heat and set aside.

  4. Layer half of the sliced potatoes in the bottom of the prepared baking dish. Season with salt and pepper to taste.
  5. Spread half of the cooked vegetable mixture over the potatoes, then sprinkle half of the shredded Pepper Jack cheese on top.
  6. Repeat the layers with the remaining potatoes, vegetables, and cheese.
  7. Pour the sour cream and milk mixture evenly over the top of the casserole.
  8. Cover the baking dish with aluminum foil and bake in the preheated oven for 45-50 minutes, or until the potatoes are tender and the cheese is melted and bubbly.
  9. Remove the foil and bake for an additional 10-15 minutes, or until the top is golden brown.
  10. Once done, remove from the oven and let it cool for a few minutes before serving.
  11. Garnish with chopped fresh parsley, if desired, and serve hot.
