Oven Baked Amish Roasted Potatoes and Onions
Prep Time: 10 minutes | Bake Time: 45-55 minutes | Total Time: Approximately 1 hour
Yield: 4 servings
Ingredients
-
2 pounds russet or yellow potatoes, scrubbed and cut into 1-inch chunks
-
2 large yellow onions, peeled and sliced into thick half-moons
-
4 tablespoons unsalted butter, melted (plus a little extra for greasing the pan)
-
1½ teaspoons kosher salt (or to taste)
Instructions
1. Preheat and Prepare:
Preheat your oven to 400°F (200°C). Lightly grease a metal baking pan (an 8×11 or 9×13 works well) with a small pat of butter so the potatoes and onions do not stick and can really crisp and caramelize.
2. Prep the Potatoes:
Scrub the potatoes well and cut them into roughly 1-inch chunks so they cook evenly. Leave the skins on for extra texture and less prep.
3. Slice the Onions:
Slice the onions into thick half-moons so they hold up in the oven. Aim for about ½-inch thickness; thinner slices will burn before the potatoes are tender.
4. Combine in the Pan:
Add the potato chunks and onion slices to the prepared baking pan, spreading them out in as even a layer as possible. A little overlap is fine, but try not to pile them too deep or they will steam instead of roast.
5. Add Butter and Salt:
Drizzle the melted butter evenly over the potatoes and onions, then sprinkle the kosher salt over the top. Use clean hands or a large spoon to toss everything right in the pan until every piece looks lightly coated in butter and seasoning.
6. Spread Evenly:
Spread the mixture back into an even layer, making sure plenty of onion slices are nestled down between the potatoes so they can soften and caramelize together.
7. First Roast (25 minutes):
Place the pan on the middle rack of the preheated oven and bake for 25 minutes without stirring, letting the bottoms start to brown and the onions begin to soften.
8. Stir and Continue:
After 25 minutes, carefully remove the pan and give everything a good toss, scraping up any golden bits from the bottom of the pan. Spread back into an even layer and return to the oven.
9. Second Roast (20-30 minutes):
Continue roasting for another 20 to 30 minutes, stirring once or twice, until the potatoes are tender all the way through, the edges are deeply golden, and the onion slices are soft, sweet, and caramelized in spots. Total time will be about 45 to 55 minutes depending on your oven and the size of your potato chunks.
10. Serve:
Taste and add a pinch more salt if needed. Serve the potatoes and onions hot, straight from the pan, making sure to scoop up the caramelized onion bits and buttery drippings from the bottom.
Recipe Notes & Pro Tips
Russet vs. Yellow Potatoes: Russet potatoes become fluffy and tender on the inside with a crispy exterior. Yukon Gold potatoes are naturally buttery and hold their shape slightly better. Both work beautifully. Do not use waxy red potatoes, which may not become as crispy.
Leave the Skins On: The skins add texture, color, and nutrients. Scrubbing the potatoes well is enough—no need to peel. The skins also help the potatoes hold their shape during roasting.
Thick Onion Slices Matter: Slicing the onions into thick half-moons (about ½ inch) ensures they soften and caramelize without burning. Thin slices will become dry and blackened before the potatoes are done.
Do Not Crowd the Pan: Overcrowding the pan causes the potatoes and onions to steam rather than roast. Use a pan large enough to hold everything in a single, mostly even layer. If necessary, use two pans.
The Stir is Important: Stirring the mixture after 25 minutes and again during roasting ensures even browning and prevents sticking. Scrape up the browned bits from the bottom—they are full of flavor.
Add Herbs (Optional): While the recipe is intentionally simple, you can add 1 teaspoon of dried thyme, rosemary, or sage along with the salt. Fresh herbs can be added in the last 5 minutes of roasting.
Add Garlic (Optional): Add 4-6 cloves of unpeeled garlic cloves to the pan. The garlic becomes soft and sweet, and you can squeeze the roasted garlic out of the skins before serving.
Variations
Garlic and Herb Potatoes: Add 4 cloves of minced fresh garlic and 1 tablespoon of fresh chopped rosemary or thyme along with the butter.
Parmesan Potatoes: Sprinkle ½ cup of grated Parmesan cheese over the potatoes and onions during the last 10 minutes of roasting. Return to the oven until the cheese is melted and golden.
Bacon Potatoes: Cook 4 slices of bacon until crisp, then crumble. Sprinkle the bacon over the roasted potatoes and onions just before serving. The smoky, salty bacon adds another dimension of flavor.
Spicy Roasted Potatoes: Add ½ teaspoon of red pepper flakes or 1 teaspoon of smoked paprika along with the salt. The paprika adds color and warmth.
Lemon Roasted Potatoes: Add the zest of 1 lemon and 2 tablespoons of fresh lemon juice during the last 5 minutes of roasting. The lemon adds brightness and cuts through the richness.
Balsamic Roasted Potatoes: Drizzle 2 tablespoons of balsamic vinegar over the potatoes and onions during the last 10 minutes of roasting. The vinegar adds tangy sweetness.
Serving Suggestions

-
Meatloaf or meatballs
-
Baked ham

Storage & Reheating
Store leftovers in an airtight container in the refrigerator for up to 5 days.
To reheat, spread the potatoes and onions on a baking sheet and warm in a 400°F oven for 5-10 minutes to restore crispiness. You can also reheat in a skillet over medium heat with a little butter. The microwave will make them soft rather than crispy.
These potatoes do not freeze well, as the texture becomes mealy upon thawing.
Why This Recipe Works
This recipe is a masterclass in simplicity. The high oven temperature (400°F) is essential for achieving crispy, caramelized exteriors while keeping the interiors tender. Metal baking pans conduct heat better than glass, promoting browning.
Cutting the potatoes into uniform 1-inch chunks ensures even cooking. Thick onion slices stand up to the heat, softening and sweetening without burning. The butter adds richness and helps with browning, while the salt enhances the natural flavors of the potatoes and onions.
The two-stage roasting method—25 minutes undisturbed, then stirring and continuing to roast—allows the bottoms to develop a golden crust before the pieces are turned. This creates more surface area for browning and ensures maximum crispiness.
This recipe is proof that you do not need a long list of ingredients or complicated techniques to create something truly delicious. With four simple ingredients and a hot oven, you can make roasted potatoes and onions that are crispy, caramelized, and deeply satisfying. Perfect for Sunday suppers, holiday dinners, or any night you want a hearty, comforting side dish.
