If you are looking for a simple, hearty, and deeply flavorful side dish that pairs with almost anything, these Oven Baked Amish Roasted Potatoes and Onions are exactly what you need. They feature golden, crispy potato chunks and sweet, caramelized onions, all roasted together with butter and a touch of salt. It is old-fashioned comfort food at its finest.
The magic of this recipe lies in the high-heat roasting process. As the potatoes and onions bake, their natural sugars caramelize, creating a deep, rich flavor and a beautifully golden exterior. The butter adds richness and helps the edges crisp up, while the salt enhances all the natural flavors. It is a simple, satisfying dish that the whole family will love.
Why This Recipe Works
This recipe relies on the perfect balance of heat and patience. Roasting at a high temperature (400°F) ensures the potatoes get crispy on the outside while staying fluffy on the inside. Slicing the onions into thick half-moons prevents them from burning before the potatoes are tender. Tossing everything halfway through cooking ensures even browning on all sides and allows the onions to caramelize beautifully.
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)
- 1 1/2 teaspoons kosher salt (or to taste)
Directions
- 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 don’t stick and can really crisp and caramelize.
- Prep the potatoes by scrubbing them well and cutting them into roughly 1-inch chunks so they cook evenly. If you’re short on time, you can leave the skins on for extra texture and less prep.
- Slice the onions into thick half-moons so they hold up in the oven. Aim for about 1/2-inch thickness; thinner slices will burn before the potatoes are tender.
- Add the potato chunks and onion slices to the prepared baking pan, spreading them out in as even a layer as you can. A little overlap is fine, but try not to pile them too deep or they’ll steam instead of roast.
- 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.
- 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.
- 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.
- 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.
- Continue roasting for another 20–30 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 45–55 minutes depending on your oven and the size of your potato chunks.
- 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.
Tips for the Best Results
Cut the potatoes evenly. Uniform 1-inch chunks cook at the same rate, ensuring you don’t end up with some potatoes turning to mush while others are still hard.
Use a metal baking pan. Metal pans conduct heat more evenly than glass, which helps the potatoes and onions achieve a deeper, crispier roast.
Don’t crowd the pan. Spread the potatoes and onions in a single layer with a little space between them. If they are too close together, they will steam instead of roast.
Stir halfway through. Tossing the potatoes and onions halfway through cooking ensures even browning and prevents them from sticking to the pan.
Watch the onions. If the onions start to brown too quickly, move them to the center of the pan and reduce the heat slightly. You want them soft and caramelized, not burnt.
Storage and Serving
Store leftover potatoes and onions in an airtight container in the refrigerator for up to 4 days. Reheat gently in a 400°F oven for 10 to 15 minutes or in an air fryer for 5 to 7 minutes to restore the crispness. These roasted potatoes and onions are the perfect side for roasted chicken, steak, pork chops, or a hearty holiday meal.
