Can I make tuna casserole without cream of mushroom soup?

Yes, you can substitute cream of mushroom soup with a homemade sauce made from 1 cup milk, 2 tablespoons butter, 2 tablespoons flour, and mushroom seasoning. Alternatively, use cream of celery or chicken soup for similar texture with different flavor profiles.

Why is my tuna casserole watery?

Watery casserole usually results from insufficiently drained tuna or overcooked noodles. Always press tuna with paper towels to remove excess liquid and undercook noodles by 1 minute since they'll continue cooking in the oven. Adding 1-2 tablespoons of breadcrumbs to the mixture can also absorb extra moisture.

How can I add more flavor to basic tuna casserole?

Boost flavor by adding 1 teaspoon Worcestershire sauce, ½ teaspoon garlic powder, or 1 tablespoon Dijon mustard to the mixture. Sautéed mushrooms and onions added before baking create deeper umami notes. A sprinkle of smoked paprika on the breadcrumb topping adds complexity without overwhelming the dish.

Can I prepare tuna casserole ahead of time?

Yes, assemble the casserole without the breadcrumb topping, cover, and refrigerate for up to 24 hours before baking. Add the topping just before baking and increase cooking time by 5-7 minutes if going from cold to oven. For longer storage, freeze unbaked casserole for up to 3 months.

What are good side dishes for tuna casserole?

Light, acidic sides balance the richness of tuna casserole best. Try a simple green salad with vinaigrette, roasted asparagus, or steamed broccoli. Crusty bread or dinner rolls work well for soaking up extra sauce. Avoid heavy starches since the casserole already contains noodles.
