Oven Baked 4-Ingredient Potatoes Whitmore
Servings: 6
Ingredients
2 pounds potatoes, peeled if desired and cut into bite-size chunks
14 ounces smoked sausage, sliced into rounds
1 large onion, sliced
4 tablespoons butter, melted
Directions
1. Preheat the oven to 400°F and lightly grease a 9x13-inch glass baking dish.
2. Add the potatoes, sausage, and onion to the baking dish, then pour the melted butter over the top. Toss well so everything is evenly coated.
3. Spread the mixture into an even layer and cover the dish tightly with foil. Bake for 35 minutes.
4. Remove the foil, stir everything well, and return the dish to the oven for 20 to 30 minutes more, until the potatoes are tender and the edges are golden.
5. Let the dish rest for 5 minutes before serving so the butter settles back over the potatoes and the flavors come together.
Variations & Tips
For picky eaters: Slice the onion extra thin so it softens right into the dish, or leave it in larger pieces so onion lovers can enjoy it and others can pick it out easily.
Budget stretch: If you need to make this go farther, add a couple more potatoes and use a slightly smaller amount of sausage. The smoky flavor still seasons the whole pan nicely.
More color: A handful of chopped parsley or a side of corn or peas brightens the plate and makes this humble supper feel a little more special.
Crispier finish: For deeper browning, bake uncovered a little longer at the end and avoid overcrowding the pan. A good even layer helps the potatoes roast instead of steam.
Make-ahead help: Cut the potatoes and onion earlier in the day and keep them chilled separately. When supper time comes, all you have to do is slice the sausage, add the butter, and bake.
