4-Ingredient Cheesy Hashbrown Casserole (Funeral Potatoes)

This classic, crowd-pleasing casserole relies on Starch Suspension and Fat Emulsion. By folding frozen shredded or diced hashbrowns directly into a creamy sour cream and soup base, the potatoes absorb the rich liquid as they bake while the cheddar forms a golden, bubbly crust across the top.

Quick Specs

• Prep Time: 10 mins
• Cook Time: 45–50 mins

The 4 Ingredients

1. Frozen Shredded or Diced Hashbrowns (30 oz bag): Thawed slightly so they mix easily.
2. Sour Cream (16 oz / 2 cups): Provides a rich, tangy creaminess that balances the savory soup.
3. Condensed Cream of Chicken Soup (1 can / 10.5 oz): The savory, seasoned gravy binder.
4. Sharp Cheddar Cheese (2 cups): Shredded, split into the filling and the golden top layer.

Pantry Staples: ½ cup melted butter, 1 tsp onion powder, salt, and black pepper to taste.

Phase 1: The Creamy Binder

• What to do: In a large mixing bowl, whisk together the sour cream, condensed cream of chicken soup, melted butter, onion powder, salt, and pepper until completely smooth and uniform.
• The Science: Combining the sour cream and condensed soup first creates a smooth emulsion. If you try to mix these directly into cold potatoes, you’ll get uneven clumps of soup instead of a creamy sauce coating every hashbrown strand.

Phase 2: The Potato Fold

• What to do: Gently fold the thawed hashbrowns and 1 cup of the shredded cheddar cheese into the creamy mixture until every piece of potato is thoroughly coated.
• The Logic: Thawing the hashbrowns slightly before mixing prevents excess ice crystals from melting during the bake, which keeps the casserole from becoming watery.

Phase 3: The Pan Set & Cheese Blanket

• What to do: Spread the potato mixture evenly into a greased 9×13-inch baking dish. Top with the remaining 1 cup of shredded cheddar cheese, covering the surface completely.
• The Physics: The top layer of cheese acts as a seal, trapping steam underneath to tenderize the hashbrowns while exposing the cheese fat directly to the oven’s dry heat for browning.

Phase 4: The Golden Bake

• What to do: Bake uncovered at 350°F (175°C) for 45 to 50 minutes.
• The Indicator: The edges should be vigorously bubbling, and the top cheese layer should turn deeply golden brown with crisp toasted spots.

Phase 5: The Setting Rest

• What to do: Remove from the oven and let the casserole rest for 10 minutes before serving.
• The Science: Straight out of the oven, the molten cheese and dairy liquids are runniest. Resting allows the potato starches to reabsorb the hot liquids, setting the casserole so it scoops neatly instead of spreading across the plate.

Serving

Scoop generous portions onto warm plates or potluck trays.

• Pairing Ideas: Excellent served alongside baked ham, pork chops, fried chicken, or as a star side dish for breakfast and brunch spreads.
