Baked Onion Casserole
A hearty baked onion casserole layered with crispy potato chips, sharp cheese, and creamy mushroom soup, perfect for a comforting family meal or potluck gathering.
Ingredients
Instructions
- Layer sliced onions, crushed potato chips, and grated cheese in a baking dish, creating at least two layers.
- In a separate bowl, combine the mushroom soup and milk until smooth.
- Pour the soup mixture evenly over the layered ingredients.
- Bake uncovered at 350°F (175°C) for 1 hour or until bubbly and golden on top.
Tips & Substitutions
For added flavor, consider sautéing the onions until they are translucent before layering them in the dish. You can substitute the sharp cheese with a milder variety if preferred, or even a mix of cheeses for a different taste. If you want a bit of crunch, use crushed crackers or pretzels instead of potato chips. This dish is perfect for gatherings, similar to Doc'S Favorite Squash Casserole.
Serving Suggestions
Serve this casserole warm as a comforting side dish alongside roasted meats or a fresh salad. It pairs beautifully with Pumpkin Harvest Loaf for a satisfying meal. You can also top with fresh herbs like parsley for a pop of color and flavor before serving.
Storage & Reheating
Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. To reheat, place in an oven at 350°F (175°C) for about 20 minutes or until heated through. You can also microwave individual portions, but the oven will help maintain the casserole's crispiness.

Frequently Asked Questions
Can I use a different type of cheese?
Yes, you can definitely experiment with different cheeses! Mild cheeses like mozzarella or pepper jack can work well, or you can use a blend of cheeses for more complexity. Just keep in mind that the flavor profile will change slightly with your choice.
How can I make this dish vegetarian?
