• 1/2 teaspoon black pepper (optional)
• Butter or cooking spray for greasing the dish

How to Make Amish Corn Potato Casserole

Step 1: Preheat the Oven

Preheat your oven to 375°F (190°C).

Lightly grease a medium ceramic casserole dish with butter or cooking spray to prevent sticking and help the edges brown nicely.

Step 2: Prepare the Potatoes

Scrub the Yukon gold potatoes thoroughly and pat them dry.

Leave the skins on for a rustic farmhouse texture, or peel them if preferred. Dice the potatoes into evenly sized 1/2-inch cubes so they cook evenly and become tender in the oven.

Step 3: Layer the Potatoes

Spread the diced potatoes evenly across the bottom of the prepared casserole dish.

Keeping them in an even layer helps ensure consistent baking throughout the casserole.

Step 4: Mix the Cream Corn Sauce

In a medium bowl, stir together the cream style corn and sour cream until smooth and fully combined.

Season with kosher salt and black pepper if desired.

Step 5: Assemble the Casserole

Pour the corn and sour cream mixture evenly over the potatoes.

Use a spoon or spatula to gently stir and coat the potatoes so the creamy mixture settles between the pieces.

Step 6: Bake Covered

Cover the casserole dish tightly with foil.

Bake for 45 minutes to allow the potatoes to steam and soften inside the creamy sauce.

Step 7: Finish Uncovered

Carefully remove the foil and gently stir the casserole.

Return it to the oven uncovered and continue baking for another 25 to 35 minutes, or until the potatoes are fork-tender and the edges are bubbling and lightly golden.

Step 8: Rest Before Serving

Allow the casserole to rest for 10 to 15 minutes before serving.

This helps the creamy sauce thicken slightly so each spoonful holds together beautifully.

Pro Tips for the Best Corn Potato Casserole

• Yukon gold potatoes provide the creamiest texture and best flavor.
• Dice the potatoes evenly for consistent cooking.
• Covering the casserole first helps the potatoes soften properly.
• Let the casserole rest before serving so the sauce thickens naturally.
• For extra browning, broil the top for 1–2 minutes at the end.

Easy Variations

Add Cheese

Stir in 1 to 1 1/2 cups shredded cheddar or Colby-Jack cheese for an extra creamy, cheesy casserole.

Add Onion

Mix in chopped onion or dried minced onion for extra savory flavor.

Make It Heartier

Add diced cooked ham, browned sausage, or shredded chicken to turn it into a complete meal.

Add More Vegetables

Frozen corn kernels or diced red bell pepper add sweetness and color.

Lighten It Up

Use light sour cream and add a splash of milk if needed to thin the mixture slightly.
