Tips & Substitutions
For a richer flavor, consider using butter instead of margarine. You can substitute fresh mushrooms for canned if desired, and add some garlic or herbs like thyme for extra depth. If you're looking for a vegetarian twist, make sure your cheese is vegetarian-friendly. This dish can easily be customized with other ingredients like spinach or bell peppers for added nutrition.
Serving Suggestions
This Onion Supreme casserole pairs beautifully with a simple side salad, like a Chef'S Salad Bowl, or crusty bread for a complete meal. You can also serve it alongside grilled vegetables or a light soup to create a hearty dinner. For an added touch, garnish with fresh herbs just before serving.
Storage & Reheating
To store leftovers, allow the casserole to cool completely, then cover it tightly with plastic wrap or transfer to an airtight container. It can be kept in the refrigerator for up to 3 days. For reheating, place it in the oven at 350°F for about 15-20 minutes until heated through, ensuring the cheese remains melty.

Frequently Asked Questions
Can I use frozen onions instead of stewed onions?
Yes, you can use frozen onions as a substitute for stewed onions. Just thaw and drain them before using to ensure the casserole doesn't become too watery. This will save you time and still provide great flavor in the dish.
What can I use instead of cream of mushroom soup?
If you don't have cream of mushroom soup, you can make a homemade alternative using a roux (flour and butter) combined with vegetable broth and mushrooms. This homemade version can be adjusted for flavor, allowing for a more personalized taste in the casserole.
Is this casserole suitable for vegetarian diets?
Yes, this casserole is vegetarian-friendly as it primarily consists of vegetables and cheese. However, always check the labels on the cheese and soup to ensure they meet your dietary needs. For a vegan option, you could use plant-based cheese and a dairy-free cream soup.
