My brother first threw these sour cream and onion potatoes together on a busy Sunday when the house was full and the clock was not on our side. He grabbed just four things, tossed it all in a glass baking dish, and slid it into the oven. By the time the roast came out, those creamy, golden potato chunks were bubbling away under a savory herb crust, smelling like the best parts of a bag of chips and a church potluck casserole rolled into one. They vanished in seconds, and now they’re our go-to when we want something that tastes like home, but comes together without a lot of fuss or fancy ingredients.
These potatoes are wonderful alongside a simple roasted chicken, meatloaf, or a pork roast with pan gravy. I like to add a bright green vegetable—steamed green beans or a crisp salad with a tangy dressing—to balance the richness. They also sit nicely on a holiday table with ham and glazed carrots, or you can serve them on their own in warm bowls for a cozy supper, maybe with a few sliced tomatoes and cucumbers on the side.
Oven Baked 4-Ingredient Sour Cream and Onion PotatoesServings: 6
Ingredients
3 pounds russet or Yukon Gold potatoes, scrubbed and cut into 1-inch chunks
2 cups full-fat sour cream
1 packet (about 1 ounce) dry onion soup and dip mix
1/4 cup chopped fresh chives, plus extra for garnish
Directions
Preheat your oven to 400°F (200°C). Lightly grease a 9x13-inch glass baking dish so the potatoes don’t stick.
In a large mixing bowl, stir together the sour cream and the dry onion soup and dip mix until the seasoning is evenly distributed and no powdery streaks remain.
Add the potato chunks to the bowl and toss well, using a big spoon or your hands, until every piece is coated in the sour cream and onion mixture.
Fold in the chopped fresh chives, reserving a small pinch if you’d like some for sprinkling on top after baking.
Spoon the coated potatoes into the prepared 9x13-inch glass baking dish, spreading them out into an even layer so they cook evenly and form a nice, lightly browned top.
Cover the baking dish tightly with foil and bake for 30 minutes, until the potatoes begin to soften and the sour cream mixture is bubbling around the edges.
Remove the foil, gently stir the potatoes to re-coat them in the sauce, then spread them back into an even layer. Return the dish to the oven, uncovered, and bake for another 25–30 minutes, or until the potatoes are very tender and the top has developed a light golden, savory crust.
Remove from the oven and let the potatoes rest for about 5 minutes so the creamy sauce thickens slightly. Sprinkle with the remaining fresh chives for a fresh, oniony pop, then serve straight from the glass dish while good and hot.
Variations & Tips
If you’d like a bit more color and texture, you can swap half the russets for red potatoes and leave the skins on; they hold their shape nicely and give the dish a farmhouse look. For a deeper onion flavor, stir in a thinly sliced fresh onion along with the potatoes before baking, or add an extra tablespoon of dry onion soup mix if your packet is on the mild side. If you prefer a lighter version, you can use light sour cream, though the sauce will be a touch thinner and less rich—just bake uncovered a little longer to help it thicken. To stretch the recipe for a crowd, add an extra pound of potatoes and a half cup more sour cream, tasting as you go and adjusting the dry mix so the seasoning stays bold. Leftovers reheat well in a covered dish at 350°F until hot, and they’re lovely crisped up in a skillet the next morning alongside eggs.
