My best friend’s mom makes this for every Sunday supper, and the smell alone is incredible. A simple 4 ingredient classic.

This Oven-Baked Amish Roasted Potatoes and Onions is a rustic, high-heat side dish that relies on the natural sugars of yellow onions to create a deep, jammy sweetness that contrasts with the salty, buttery crust of the potatoes. By roasting at 400°F, the butter undergoes a slight browning process, infusing the vegetables with a nutty aroma while the onions “melt” into the crevices of the potato chunks. The result is a simple, four-ingredient masterpiece that delivers a “fried-in-a-skillet” flavor with the effortless consistency of an oven roast.

Oven Baked Amish Roasted Potatoes and Onions

Ingredients:

Step-by-Step Directions:

Step 1: The Chunky Prep: Preheat your oven to 400°F. Grease a metal baking pan with a small pat of butter. Cut your scrubbed potatoes into uniform 1-inch chunks and slice your onions into thick 1/2-inch half-moons.

Tip: The thickness of the onion slices is a vital “mechanical” step. If you slice the onions too thin, they will incinerate into bitter black wisps long before the potatoes reach tenderness. Keeping them thick allows them to caramelize slowly into “sweet gold.”

Step 2: The Butter Toss: Add the potatoes and onions to the pan. Drizzle with melted butter and sprinkle with salt. Toss everything together until every surface is glossy and coated.

Step 3: The Initial Sizzle: Spread the vegetables into an even layer. Bake for 25 minutes without stirring.

Tip: Leaving the vegetables undisturbed for the first half of the bake is essential. It allows the surface in contact with the metal pan to develop a “sear,” ensuring the potatoes have a distinct, crispy bottom.

Step 4: The Caramelization Stir: Remove the pan and toss the vegetables, scraping up the golden bits from the bottom. Roast for another 20/30 minutes, stirring once or twice more.

The Visual Cue: You are looking for potatoes that are fork-tender with shattered, crispy edges and onions that have shrunk and turned a deep amber color.

Step 5: The Hot Serve: Taste for seasoning and serve immediately. Ensure you scrape the pan to collect the “drippings”—that concentrated mixture of butter and onion sugar is where the best flavor lives.
