This oven baked 4-ingredient pimento cheese potato casserole is exactly the kind of rich, no-fuss side dish my Southern aunt would bring to every family gathering. It leans on the classic Southern love affair with pimento cheese—sharp cheddar, sweet pimentos, and a creamy base—melted over tender cubed potatoes until everything is bubbling and golden on top. With just four ingredients and one baking dish, it’s practical for weeknights yet indulgent enough for holidays, potlucks, or any time you need a guaranteed crowd pleaser.
Serve this casserole hot, straight from the oven, with simple proteins like roast chicken, grilled pork chops, or seared steak to balance its richness. A crisp green salad with a tangy vinaigrette or lightly steamed green beans will cut through the creaminess nicely. It also works beautifully on a holiday table beside ham, turkey, or meatloaf, and the leftovers reheat well for brunch alongside scrambled eggs or a slice of toast.
Oven-Baked 4-Ingredient Pimento Cheese Potato CasseroleServings: 6-8
Ingredients
2 1/2 pounds russet or Yukon Gold potatoes, peeled and cut into 1/2-inch cubes
2 cups prepared pimento cheese spread, loosely packed
1 cup sour cream
1 teaspoon kosher salt (plus more to taste)
Directions
Preheat your oven to 375°F (190°C). Lightly grease a medium ceramic baking dish (about 2 to 2 1/2 quarts) with a bit of neutral oil or nonstick spray.
Place the cubed potatoes in a large pot and cover with cold water by about 1 inch. Add a generous pinch of salt. Bring to a boil over medium-high heat, then reduce to a simmer and cook until the potatoes are just fork-tender, 8–10 minutes. They should hold their shape and not be falling apart.
Drain the potatoes well in a colander, then let them sit for 2–3 minutes so excess steam can escape. This helps them better absorb the creamy mixture without becoming watery.
In a large mixing bowl, stir together the pimento cheese spread, sour cream, and 1 teaspoon kosher salt until mostly smooth and evenly combined. The mixture will be thick and a bit lumpy from the cheese shreds, which is perfect.
Add the warm, drained potato cubes to the bowl with the pimento cheese mixture. Gently fold everything together with a spatula until all the potatoes are well coated. Taste a piece and adjust the salt if needed.
Transfer the coated potatoes to the prepared ceramic baking dish, spreading them into an even layer. Use the spatula to lightly press the mixture down so there are no large air pockets, but don’t mash the potatoes—you want distinct, tender cubes smothered in cheese.
Bake, uncovered, in the preheated oven for 25–30 minutes, until the casserole is bubbling around the edges and the top is melted, glossy, and beginning to turn a deeper golden orange.
For a crispier top, move the dish to the upper third of the oven and bake for an additional 5–10 minutes, or briefly broil on high for 1–3 minutes, watching closely so the cheese doesn’t burn. You’re aiming for a lightly crisp, browned surface over gooey, melted pimento cheese underneath.
Remove the casserole from the oven and let it rest for about 5–10 minutes before serving. This short rest allows the cheese to thicken slightly so each spoonful holds together while still staying luscious and creamy.
Serve the casserole directly from the ceramic baking dish, scooping down to reveal the tender, cheesy potatoes beneath the crisp top. Any leftovers can be cooled, covered, and refrigerated, then reheated in a low oven until warmed through.
Variations & Tips
To keep the spirit of the original four-ingredient recipe, treat any additions as optional flourishes. For a bit of heat, stir a pinch of cayenne or a few dashes of hot sauce into the pimento cheese mixture before folding in the potatoes. If you prefer a looser, saucier casserole, add 2–4 tablespoons of milk or half-and-half when you mix the pimento cheese and sour cream. For extra texture, you can sprinkle a light layer of crushed buttery crackers or plain breadcrumbs over the top before baking, though it does technically add another ingredient. A sharper, more pronounced cheese flavor comes from using a very sharp or extra-sharp cheddar-based pimento cheese spread. If you need to make this ahead, assemble the casserole up to a day in advance, cover, and refrigerate; add 5–10 minutes to the baking time and uncover for the last 15 minutes to crisp the top. Finally, if you’re cooking for a smaller household, bake the mixture in two smaller dishes and freeze one (unbaked, tightly wrapped) for later—just thaw in the fridge overnight and bake as directed.
