Tuna Macaroni Casserole Recipe (2024)

FAQs

Why is my tuna casserole so dry? ›

Tuna casserole can become dry if it's overcooked or if there isn't enough moisture in the dish. Be sure to follow the recipe instructions and adjust the cooking time as needed to prevent it from drying out.

To prevent a soupy casserole, be sure to fully thaw any frozen vegetables in a colander over a bowl, and pat dry, squeeze excess moisture out of greens like spinach or chard, and quickly precook watery fresh vegetables like onions, mushrooms or squashes just until they release their moisture.

Make a cornstarch slurry for a fast and easy thickener.

Use one tablespoon of cornstarch per cup of liquid you would like to thicken. Stir out all the lumps. A few minutes before your casserole is done, add it a little at a time until you are happy with the thickness. Then, let the casserole finish baking.

Store your leftover tuna noodle casserole in a shallow, airtight container in the fridge for up to four days. Reheat thoroughly in the oven or in the microwave.

Pro Tip: Avoid Dry Casserole.

The best way to prevent it from drying out is to add a little bit of water, around ¼ cup, to the top of it. Allow the water to seep between the food and the sides of the baking dish. Cover with aluminum foil to seal in the moisture.

Uncovering the foods promotes browning and crisping, and reduces the amount of liquid in the finished dish. If a casserole looks soupy when it's ready to bake, bake it uncovered unless the ingredients include pasta or rice, which absorb liquid.

The time a casserole takes to cook will vary from 2-2½ hours for chuck, blade and thick flank, up to 4 hours for shin, leg and neck. Pork cuts for braising and casseroling normally take 1½ hours, and lamb much the same.

Always Double Check With A Thermometer

The safest way to know if any casserole is cooked is to check it with a quick-read thermometer. If you don't have one, you should definitely invest in one, because it will save you a lot of trouble whether you're cooking meat, bread, or even baked potatoes.

How to fix a runny casserole? ›

Keep food cold by nesting dishes in bowls of ice or use small serving trays and replace them often. Discard any cold leftovers that have been left out for more than 2 hours at room temperature (1 hour when the temperature is above 90 °F).

The pasta absorbs liquid, so you should use a generous amount of sauce to keep the dish moist. Your tuna casserole can also become dry due to overbaking. Even if it turns out perfect when you first cook it, it may still dry out when you reheat it. Luckily, these mistakes are quite easy to fix.

Lastly, you can freeze cooked tuna casserole if you cannot eat it within 3-4 days. Whether it's fresh out of the oven or leftovers, you can freeze it in an airtight container for up to 3 months. If straight from the oven, allow it to cool completely before sealing it so it doesn't continue to cook.

Add a little moisture to the mix

But if you're averse to the white and creamy condiment or don't have it in your fridge, here are some other great options that add moisture and make tuna palatable: Oil. Olive, truffle, and even toasted sesame (which I use in my recipe below) are just a few drool-worthy examples.

Tuna dries out quite quickly and turns crumbly, so it should be cooked very briefly over a high heat in a frying pan, on a griddle or over a barbecue; or cooked under oil (confit), sous vide or simmered in a sauce.

Alternatively, Foods Guy recommends adding a splash of water or chicken stock to your casserole and covering it with plastic wrap before microwaving, which will add new moisture and lock in the steam, ensuring a perfectly moist reheated tuna casserole.

To prevent your tuna salad from being dry, you'll need to stir in at least one tablespoon mayo per one (5-ounce) can of tuna. After mixing in the rest of your ingredients, taste the salad. If you want it creamier, stir in another tablespoon or two of mayo. A squeeze of lemon juice also adds moisture.
