Is tuna casserole supposed to be covered when cooking?

Here's the breakdown:

* If your recipe calls for baking: It's usually best to cover the casserole with foil for the first part of the baking time. This helps the casserole cook evenly and prevents the top from browning too quickly. Towards the end of the baking time, you can remove the foil to allow the top to brown and get crispy.

* If your recipe calls for stovetop cooking: You generally don't need to cover the casserole. However, keep an eye on it and adjust the heat as needed to prevent it from burning.

Always follow the instructions in your specific recipe.

Here are some tips for a perfect tuna casserole:

* Use good quality tuna: Look for tuna packed in water or oil, not brine.

* Don't overcook the noodles: They should be cooked al dente (slightly firm to the bite).

* Use a creamy sauce: A creamy sauce will help to bind the casserole together and add richness.

* Add some crunch: Toasted breadcrumbs, chopped nuts, or crispy fried onions can add a nice textural contrast.

Enjoy!
