Ingredients
1 can Spam, sliced into thin pieces
4 medium Russet potatoes, peeled and sliced into thin, even rounds
1 cup milk
Instructions
1. Prepare the Oven and Baking Dish
Preheat your oven to 350°F. Lightly grease a medium glass baking dish to prevent the potatoes from sticking.
2. Slice the Potatoes and Spam
Peel the 4 Russet potatoes and slice them into thin, even rounds. For the most consistent cooking, try to keep the potato slices approximately ⅛-inch thick. Slice the Spam into thin pieces as well.
3. Create the First Layer
Arrange half of the potato slices evenly across the bottom of the prepared baking dish. Layer half of the sliced Spam over the potatoes.
4. Add the Remaining Layers
Add the remaining potato slices over the Spam. Finish by arranging the remaining Spam slices on top, creating two even layers of potatoes and Spam.
5. Add the Milk
Slowly pour 1 cup of milk evenly over the entire casserole. Pouring it gradually helps the milk work its way between the layers.
6. Cover and Bake
Cover the baking dish tightly with aluminum foil. Place it in the preheated oven and bake for 1 hour. Keeping the casserole covered helps trap steam so the potatoes can become tender.
7. Finish Baking
Carefully remove the foil and return the casserole to the oven. Bake uncovered for another 20–30 minutes, or until the potatoes are fork-tender and the exposed edges are lightly browned.
8. Rest and Serve
Remove the casserole from the oven and allow it to rest for 10 minutes before serving. This gives the casserole time to settle and makes it easier to portion.
