A quick and hearty tuna casserole featuring crispy onion rings, tender mushrooms, and a creamy celery sauce, perfect for a comforting weeknight dinner.
Ingredients
Instructions
- Combine half of the onion rings with drained tuna, chopped celery, drained mushrooms, onion powder, and cream of celery soup in a greased casserole dish.
- Bake at 350°F (175°C) for 25 minutes.
- Sprinkle the remaining onion rings on top of the casserole.

Tips & Substitutions
For a creamier texture, consider adding a dollop of sour cream or Greek yogurt to the mixture. If you don't have celery soup, cream of mushroom or chicken soup can be a good substitute. To add extra flavor, include a teaspoon of Worcestershire sauce or a sprinkle of paprika. Feel free to incorporate other vegetables like peas or corn for variety.
Serving Suggestions
This casserole pairs beautifully with a simple side salad or some steamed vegetables for a complete meal. Consider serving it alongside a light dish like Tossed Tuna Salad for a refreshing contrast. For an added crunch, serve with crusty bread or garlic toast, which complements the creamy casserole perfectly.
Storage & Reheating
Store any 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 sure to cover them to retain moisture.

Frequently Asked Questions
Can I use fresh vegetables instead of canned?
Absolutely! Fresh vegetables like chopped bell peppers, carrots, or green beans can enhance the flavor and texture of your casserole. Just make sure to sauté them slightly before adding to the mix to ensure they cook through during baking.
Is there a way to make this dish gluten-free?
Yes, to make this casserole gluten-free, ensure the cream of celery soup is gluten-free or make your own. Substitute the French fried onion rings with gluten-free alternatives or simply omit them for a delicious, crunchy topping.
Can I prepare this casserole ahead of time?
Yes, you can prepare the casserole up to the baking stage and store it in the refrigerator for up to 24 hours before baking. Just cover it well to prevent it from drying out. When ready to bake, add a few extra minutes to the cooking time if baking straight from the fridge.
