My husband loved it so much after trying it that he asked me to whip up another batch for his office potluck. It only takes four simple ingredients.

 Southern 4‑Ingredient Hashbrown Casserole

Creamy, cheesy, and impossibly simple—no canned soup required.

This is the kind of dish that disappears fast at holiday brunches, potlucks, and Sunday suppers. Instead of relying on condensed soup for creaminess, it uses a rich sour cream base that gives every bite a tangy, velvety smoothness. Tender shredded hashbrowns soak up all that goodness, while sharp cheddar melts into gooey pockets inside and forms a golden, lightly crisp crown on top.

With just four main ingredients (plus salt), it’s proof that comfort food doesn’t need a long grocery list to deliver big flavor.

Frozen shredded hashbrowns, thawed	1 bag (30–32 oz)
Sharp cheddar cheese, shredded (divided)	3 cups
Sour cream	2 cups
Kosher salt	1 teaspoon

Instructions

1. Prep the oven and pan
   Preheat your oven to 350°F (175°C). Lightly grease a 9×13‑inch baking dish with butter or cooking spray.

2. Dry the potatoes (key step!)
   After thawing the hashbrowns, place them in a clean kitchen towel or a stack of paper towels and press firmly to remove as much excess moisture as possible. This prevents a watery, soggy casserole and keeps the texture rich and creamy.

3. Mix the base
   In a large bowl, whisk the sour cream and salt together until completely smooth.

4. Combine everything
   Add the dried hashbrowns to the bowl and toss well until every shred is coated in the sour cream mixture. Then gently fold in 2 cups of the shredded cheddar. (Feel free to taste the mixture here and adjust salt—just remember the cheese will add more saltiness as it bakes.)

5. Assemble
   Transfer the mixture to your prepared baking dish and spread it into an even layer, pressing down lightly. Sprinkle the remaining 1 cup of cheese evenly over the top.

6. Bake
   Place the dish uncovered in the oven and bake for 40–45 minutes, until the casserole is hot, bubbly around the edges, and the top is lightly golden.

   Pro tip: For an extra-crispy, browned topping, move the dish to the upper rack during the last 5–10 minutes of baking—just keep an eye on it so the cheese doesn't burn.

7. Rest before serving
   Remove from the oven and let the casserole sit for at least 10 minutes. This resting time allows it to set up, so you can slice and serve neat, picture-perfect portions.

Serving & Storage Tips

• Pair it with scrambled eggs, crispy bacon, or a fresh fruit salad for a complete breakfast or brunch. It also shines alongside roasted meats or a simple green salad for lunch or dinner.

• Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat in the oven or toaster oven to bring back that crispy top—the microwave works in a pinch, but it will soften the crust.

Creamy, cheesy, and wonderfully unfussy—this casserole proves that a short list of ingredients can still deliver the kind of hearty, soul-warming comfort that keeps everyone coming back for seconds.
