This cozy pan of oven baked 4-ingredients french onion roasted potatoes is straight from my aunt’s little box of handwritten recipes. She swears the secret to melt-in-your-mouth potatoes is letting them roast low and slow in a rich french onion broth until the onions turn deep and caramelized and the potatoes soak up every bit of flavor. It’s the kind of simple, no-fuss side dish you can toss together on a busy weeknight or slide into the oven for Sunday dinner, and it tastes like you fussed a whole lot more than you did.
Serve these french onion roasted potatoes straight from the baking dish while they’re still bubbling and golden. They’re wonderful alongside roast chicken, pork chops, or a simple grilled steak, and they make a hearty partner for meatloaf or baked ham. Add a crisp green salad or steamed green beans to balance the richness, and if you’re feeding a crowd, a loaf of crusty bread is perfect for soaking up the dark, savory broth at the bottom of the pan.
Oven Baked 4-Ingredients French Onion Roasted PotatoesServings: 6
Ingredients
3 pounds yellow or gold potatoes, scrubbed and cut into 1-inch chunks
2 (10.5-ounce) cans condensed French onion soup
1 large yellow onion, thinly sliced
3 tablespoons unsalted butter, cut into small pieces
Directions
Preheat your oven to 375°F (190°C). Lightly grease a 9x13-inch white ceramic baking dish or a similar-sized casserole dish.
Spread the potato chunks evenly in the baking dish. Try to keep them in a mostly single layer so they roast and brown nicely.
Scatter the thinly sliced onion over the potatoes, tucking some slices down between the potatoes so they can caramelize in the broth as they cook.
Pour the condensed French onion soup evenly over the potatoes and onions. There’s no need to dilute it with water; the concentrated soup is what gives you that rich, dark broth.
Dot the top with the pieces of butter, spacing them out so they melt and baste the potatoes as they bake.
Cover the baking dish tightly with foil and bake for 45 minutes. This helps the potatoes soften and start to soak up the french onion flavor.
Carefully remove the foil, give everything a gentle stir to coat the potatoes in the broth and onions, then spread them back into an even layer.
Return the uncovered dish to the oven and continue baking for 30 to 40 minutes, stirring once more halfway through, until the potatoes are very tender, the edges are deeply browned, and the onions are caramelized and swimming in a dark, savory broth.
Let the dish rest for about 5 minutes before serving so the bubbling settles. Spoon the potatoes, onions, and plenty of that rich broth into bowls or onto plates and serve warm.
Variations & Tips
For picky eaters, peel the potatoes before cutting them; the texture will be even softer and more familiar for kids. If your family likes things extra rich, add an extra tablespoon of butter on top before baking uncovered, or sprinkle a small handful of shredded mozzarella or Swiss cheese over the potatoes during the last 10 minutes of baking so it melts into the onions and broth. To stretch the dish for a crowd, stir in a few extra potatoes and a splash of water or beef broth along with a pinch of salt to balance the extra liquid. You can also swap yellow potatoes for red potatoes or russets; just cut them to a similar size and check for doneness a few minutes earlier. For a make-ahead option, assemble the dish up to the point of covering with foil and refrigerate for up to 24 hours, then bake straight from the fridge, adding 5 to 10 extra minutes to the covered baking time. If you prefer crispier edges, move the dish to the top rack for the last 5 minutes of baking and let the potatoes brown a bit more before serving.
