A creamy, cheesy hashbrown casserole with sweet caramelized onions, Gruyère, and a crispy buttery topping. The ultimate comfort food that steals the spotlight at every gathering.

  • Total Time: 1 hour 15 minutes
  • Yield: 8 servings 1x

Ingredients

Scale
  • 1 (30 oz) bag frozen shredded hashbrowns, thawed
  • 2 large yellow onions, thinly sliced
  • 2 tbsp butter (for onions)
  • 1 tsp sugar (for onions)
  • 1 cup sour cream (full-fat)
  • 1 can cream of chicken soup
  • 1 ½ cups shredded Gruyère cheese
  • 1 cup sharp cheddar cheese
  • ½ tsp garlic powder (optional)
  • ½ tsp black pepper
  • 1 ½ cups crushed Ritz crackers or crispy fried onions
  • 2 tbsp melted butter (for topping, if using crackers)

Instructions

  1. Preheat oven to 350°F (175°C).
  2. Caramelize onions: In a large skillet over low heat, melt 2 tbsp butter and cook onions with sugar, stirring occasionally until deep golden and jammy (about 30–35 minutes). Or use 1 packet of French onion soup mix as a shortcut.
  3. In a large bowl, mix cream of chicken soup, sour cream, caramelized onions (or soup mix), Gruyère, cheddar, garlic powder, and pepper.
  4. Fold in thawed hashbrowns gently until fully coated.
  5. Grease a 9×13-inch baking dish and spread the mixture evenly inside.
  6. For topping: toss crushed crackers with melted butter or use crispy fried onions directly. Sprinkle evenly over the top.
  7. Bake uncovered for 45 minutes or until golden and bubbly.
  8. Let rest for 10 minutes before serving for best texture.

Notes

For best flavor, use full-fat dairy and grate your own cheese. Toast your topping before adding for extra crunch. Great make-ahead dish—just assemble and refrigerate before baking.
