This is the kind of cozy, hands-off potato dish I lean on for slow Sundays when I want dinner handled hours ahead. With just five ingredients, everything bakes down into one caramelized, glistening mass—crispy and browned on top, creamy and tender underneath. It reminds me of the simple potato bakes my mom made in our small Midwestern kitchen, the kind you slide into the oven and forget about while the house fills with that buttery, savory smell. It’s perfect for when you’re hosting family or just want something comforting bubbling away while you do a puzzle, fold laundry, or cheer on a game.
Serve these oven spring potatoes alongside roasted chicken, pork chops, or a simple pan-seared steak for a full Sunday dinner. They’re also lovely next to baked salmon or a big green salad if you want something lighter. I like to add a bright side—steamed green beans with lemon, peas with a bit of butter, or a simple tomato-cucumber salad—to balance the rich, caramelized potatoes. Leftovers reheat beautifully and make a great base for breakfast the next morning with a fried egg on top.
5-Ingredient Spring Sunday Oven Potatoes
Servings: 6

Ingredients
3 pounds small yellow or red new potatoes, scrubbed and quartered
1 large yellow onion, thinly sliced
1/3 cup olive oil (or neutral oil)
2 teaspoons kosher salt
1 teaspoon freshly ground black pepper
Directions
Preheat your oven to 375°F (190°C). Lightly grease a medium ceramic baking dish (about 9x13 inches or similar) with a bit of the oil, just enough to coat the bottom and sides.
Prep the vegetables: Scrub the new potatoes well and pat them dry. Cut them into even bite-sized pieces—halves or quarters depending on size—so they cook at the same rate. Thinly slice the onion from root to tip into half-moons.
In a large bowl, combine the potatoes and sliced onion. Drizzle with the olive oil, then sprinkle the kosher salt and black pepper evenly over the top. Use clean hands or a large spoon to toss until every piece is well coated and the seasonings look evenly distributed.
Transfer the potato and onion mixture to the prepared ceramic baking dish, spreading it out into an even layer. Gently press everything down so it forms a snug, slightly packed mass—this helps the bottom and middle stay creamy while the top caramelizes.
Cover the dish tightly with foil. Bake covered for 45 minutes, until the potatoes are starting to turn tender when pierced with the tip of a knife and the onions are soft and fragrant.
Remove the foil, give everything a gentle stir, then press the potatoes and onions back down into an even layer again. Return the dish to the oven, uncovered, and continue baking for 35–45 minutes, stirring once more halfway through, until the top is deeply golden, edges are caramelized, and the potatoes are very tender and creamy inside.
For extra caramelization, in the last 5–10 minutes, increase the oven temperature to 400°F (200°C) and let the top darken and crisp, watching closely so it doesn’t burn. The finished dish should look like a glistening, browned, slightly sticky mass with soft, steamy potatoes underneath.
Once done, remove the dish from the oven and let the potatoes rest for 10–15 minutes. This short rest helps the flavors settle and the creamy interior texture develop even more. Serve straight from the ceramic dish, scooping down to get both the caramelized top and the soft, saucy potatoes below.
Variations & Tips
For picky eaters, you can dice the onion very small so it melts into the potatoes instead of showing up in big slices—kids are less likely to pick it out. If your family likes a little extra richness, drizzle 2 tablespoons of melted butter over the potatoes during the last 15 minutes of baking (this doesn’t count as an official ingredient if you think of it as a finishing touch). For a brighter, more springy feel, toss in a handful of chopped fresh herbs like parsley or chives after baking; set some plain potatoes aside before adding herbs if anyone objects to “green bits.” If you need to prep even further ahead, assemble the dish up to the point of baking, cover, and refrigerate for up to 8 hours; add an extra 10–15 minutes to the covered bake time if going straight from the fridge. To stretch this for a bigger crowd, serve the potatoes over a bed of baby spinach in a large bowl—the heat will gently wilt the greens and turn it into a hearty side. Leftovers can be crisped in a skillet the next morning and topped with eggs or a sprinkle of cheese for an easy second meal.
