Prep Time: 15 minutes
Cook Time: 4–5 hours on LOW or 2–3 hours on HIGH
Total Time: Approximately 5 hours
Servings: 6

Ingredients

Just 3 Main Ingredients

  • 2 lbs (900 g) potatoes, peeled and sliced into ¼-inch rounds

  • 2 large yellow onions, thinly sliced

  • ½ cup (115 g) butter, melted

Optional Seasonings

  • Salt, to taste

  • ½ teaspoon black pepper

  • ½ teaspoon paprika

  • ½ teaspoon garlic powder

Instructions

1. Prepare the potatoes: Wash, peel, and slice the potatoes into even ¼-inch rounds. Keeping the slices similar in thickness helps them cook evenly.

2. Slice the onions: Peel the onions and cut them into thin slices. Separate the slices gently with your fingers.

3. Prepare the slow cooker: Lightly grease the inside of a 5–6-quart slow cooker with a little butter to prevent sticking.

4. Start layering: Arrange a layer of potato slices across the bottom of the slow cooker. Add a layer of sliced onions over the potatoes.

5. Continue layering: Alternate layers of potatoes and onions until all the ingredients have been used. Finish with a layer of onions if possible.

6. Add the butter: Pour the melted butter evenly over the layered potatoes and onions, allowing it to reach all the layers.

7. Season: Sprinkle with salt, black pepper, paprika, and garlic powder if desired.

8. Slow cook: Cover and cook on LOW for 4–5 hours or HIGH for 2–3 hours, until the potatoes are fork-tender. Cooking time depends on potato thickness and your slow cooker.

9. Check tenderness: Carefully insert a fork into the center. The potatoes should be soft and easily pierced.

10. Serve: Gently lift the potatoes and buttery onions with a serving spoon, making sure to scoop up the delicious buttery juices. Serve warm.

Description

This Old-Fashioned Depression-Era Potato and Onion Bake celebrates the beauty of simple cooking. Thinly sliced potatoes are layered with onions and melted butter, then slowly cooked until everything becomes tender and flavorful.

As the onions soften, they release their natural sweetness and blend with the butter, creating a delicious coating for the potatoes. There is no complicated sauce, no expensive ingredients, and no special cooking equipment required beyond a slow cooker.

It’s a wonderful side dish for family dinners, holiday meals, or any time you want something warm and comforting.

Recipe Notes

  • Potatoes: Russet potatoes become soft and fluffy, while Yukon Gold potatoes hold their shape a little better.

  • Onions: Yellow onions are ideal because they become sweet and tender during slow cooking.

  • Butter: Salted or unsalted butter can be used. Adjust additional salt accordingly.

  • Layering: Keep the potato slices relatively even so they cook at the same rate.

  • Texture: This recipe produces soft, buttery potatoes rather than crispy roasted potatoes.

  • Optional seasoning: The original three-ingredient version is delicious on its own, but herbs and spices can add extra flavor.

Helpful Tips

  1. Slice the potatoes evenly to prevent some pieces from becoming mushy while others remain firm.

  2. Avoid cutting the onions too thick because thinner slices soften more easily.

  3. Spread the melted butter evenly over the layers.

  4. Avoid lifting the slow cooker lid too often during cooking.

  5. Check the potatoes toward the lower end of the cooking time to prevent overcooking.

  6. For a golden top, transfer the cooked potatoes to an oven-safe dish and briefly broil until lightly browned.

Serving Suggestions

Serve these buttery potatoes alongside:

  • Roasted chicken

  • Baked ham

  • Pork chops

  • Slow cooker beef roast

Storage and Reheating

Refrigerator: Store leftover potatoes and onions in an airtight container for up to 3–4 days.

Freezer: Freezing is possible, but potatoes may become softer or grainier after thawing. For best texture, enjoy them fresh or refrigerated.

Reheating: Warm in a covered skillet over medium-low heat with a small splash of water or a little butter. You can also microwave individual portions until heated through.

Frequently Asked Questions

1. Can I use red potatoes instead of russet potatoes?

Yes. Red potatoes hold their shape well and create a slightly firmer texture.

2. Do I need to add water or broth?

No. The onions release moisture as they cook, and the butter coats the potatoes. Additional liquid is generally unnecessary.

3. Can I prepare this recipe the night before?

You can peel and slice the potatoes and onions ahead of time. Keep the potatoes submerged in cold water in the refrigerator to prevent browning, then drain and dry them thoroughly before layering. Prepare the onions separately.

4. Can I add cheese?

Absolutely! Sprinkle shredded cheddar over the potatoes during the final 15–20 minutes of cooking for a cheesy variation.

5. Can I make this recipe in the oven?

Yes. Layer the ingredients in a covered baking dish and bake at 375°F (190°C) for approximately 50–65 minutes, or until the potatoes are tender. Check occasionally to prevent drying.

6. Why are my potatoes still hard?

The slices may be too thick, the slow cooker may cook at a lower temperature, or the layers may be too crowded. Continue cooking until the potatoes are fork-tender.

7. Can I add garlic and herbs?

Yes! Fresh garlic, rosemary, thyme, or parsley can add wonderful flavor. These are optional additions and are not part of the original three-ingredient recipe.
