 Oven Baked 3-Ingredient Canned Spam Potato Casserole

Oven Baked 3-Ingredient Canned Spam Potato Casserole is a simple, hearty comfort-food dish made with just three main ingredients. Sliced potatoes bake together with savory canned Spam and melted cheddar cheese until everything is tender, creamy, and golden around the edges.

It is an affordable pantry-friendly casserole that works well for an easy family dinner, especially when you want something filling without a long ingredient list.

Ingredients

• 2 cans (12 ounces each) canned Spam, sliced into thin strips or small cubes
• 2½ pounds Yukon Gold potatoes, thinly sliced
• 1½ cups shredded cheddar cheese

How to Make Canned Spam Potato Casserole

1. Prepare the oven: Preheat the oven to 375°F (190°C). Lightly grease a 9-by-13-inch baking dish.
2. Prepare the potatoes: Wash and thinly slice the potatoes. Keeping the slices relatively even helps them cook at the same rate.
3. Layer the casserole: Arrange about half of the potatoes in the bottom of the baking dish. Add half of the Spam evenly over the potatoes, followed by half of the cheddar cheese.
4. Repeat the layers: Add the remaining potatoes, Spam, and cheddar cheese.
5. Cover and bake: Cover the dish tightly with foil and bake for 45–55 minutes, or until the potatoes are tender when pierced with a fork.
6. Brown the top: Remove the foil and continue baking for 15–20 minutes, until the cheese is melted and golden around the edges.
7. Rest and serve: Let the casserole rest for about 10 minutes before slicing and serving.

Tips for the Best Spam Potato Casserole

• Slice the potatoes evenly so they cook consistently.
• Because canned Spam is already fully cooked and salty, additional salt usually isn’t necessary.
• Thinly slicing the Spam helps distribute its savory flavor throughout the casserole.
• Keep the casserole covered during the first part of baking so the potatoes steam and become tender.
• Let the casserole rest before serving so the layers can settle.

Easy Variations

If you are not strictly keeping the recipe to three ingredients, add sliced onion, black pepper, garlic powder, or smoked paprika.

For a different flavor, replace some of the cheddar with Monterey Jack or Colby Jack.

You can also lightly brown the Spam pieces in a skillet before layering. This gives the edges a crispier texture.

What to Serve With It

Because this casserole is hearty and savory, it pairs nicely with lighter sides such as a green salad, steamed green beans, broccoli, or roasted vegetables.

For a simple breakfast-style meal, serve it with eggs and fresh fruit.

Storage

Cool leftovers promptly and store them in an airtight container in the refrigerator for 3–4 days.

Reheat individual portions in the microwave or reheat the casserole covered in a 350°F oven until hot throughout.

The casserole can also be frozen for up to 2 months, although the potatoes may become slightly softer after thawing.

Frequently Asked Questions

Do I need to cook the Spam first?

No. Canned Spam is already cooked, so it can go directly into the casserole. Browning it first is optional if you want crispier edges.

Should I add salt?

Usually not. Spam and cheddar already contain salt, so taste the finished dish before adding any additional seasoning.

Can I use russet potatoes?

Yes. Russet potatoes work well, although Yukon Gold potatoes provide a creamier texture and tend to hold their shape nicely.

Can I prepare this ahead of time?

Yes. Assemble the casserole, cover it tightly, and refrigerate it for up to 24 hours. Add some extra covered baking time if baking directly from the refrigerator.

Oven Baked 3-Ingredient Canned Spam Potato Casserole is an easy pantry-friendly meal that keeps things simple without sacrificing comfort. Savory canned Spam, tender potatoes, and melted cheddar create a hearty casserole with a golden, cheesy finish.
