Tips & Substitutions
For added flavor, consider adding sautéed garlic or herbs like thyme or rosemary to the onions. If you prefer a crunchier topping, use panko breadcrumbs instead of crushed saltines. You can also substitute the sharp Cheddar with Gruyère or mozzarella for a different taste. To make this dish gluten-free, use gluten-free crackers.
Serving Suggestions
This casserole pairs wonderfully with a simple green salad or steamed vegetables for a balanced meal. For a heartier option, serve it alongside roasted chicken or pork. It also makes a great side dish for a potluck or family gathering, complementing other comfort foods like macaroni and cheese or meatloaf.
Storage & Reheating
Store leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, place the casserole in a preheated oven at 350°F (175°C) for about 15-20 minutes, or until heated through. You can also microwave individual portions, but be cautious as it may not retain its crispy topping.

Frequently Asked Questions
Can I make this casserole ahead of time?
Yes, you can prepare the casserole up to a day in advance. Assemble it completely, cover it tightly, and refrigerate. When you're ready to bake, allow it to come to room temperature before placing it in the oven, or adjust the baking time accordingly if baking straight from the fridge.
What can I use instead of mushroom soup?
