Ingredients

  • 5 to 7 medium onions
  • 1 large bag potato chips
  • 1/2 lb. grated mild cheese
  • 2 cans cream of mushroom soup
  • 1/2 cup milk

Instructions

  1. In a buttered casserole dish, layer thinly sliced onions, potato chips, and grated cheese.
  2. Repeat the layering process until all ingredients are used.
  3. Pour the cream of mushroom soup and milk evenly over the layered ingredients.
  4. Bake at 350°F (175°C) for 1 hour until bubbly and golden.

Tips & Substitutions

For added flavor, consider using a mix of onions, such as sweet and red varieties. You can substitute the cream of mushroom soup with homemade cream of celery soup for a different taste. If you're looking for a healthier option, opt for baked potato chips or a whole grain variety. Adjust the cheese type according to your preference, or try a blend of cheeses for more complexity.

Serving Suggestions

This dish pairs wonderfully with a fresh green salad or steamed vegetables to balance the richness. Consider serving it alongside grilled meats for a hearty meal, or as a comforting side for dishes like Steak N' Mushroom Casserole. A dollop of sour cream or a sprinkle of chives on top can enhance the flavors and presentation.

Storage & Reheating

Once cooled, store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, place in a preheated oven at 350°F (175°C) for about 20 minutes, or until heated through. You can also microwave individual portions for a quick meal, but the oven will help maintain the texture of the potato chips.
