Casseroles have existed in many different places, and many cultures have their own version of the dish. In fact, the term casserole actually has two meanings: it can either be the large, deep-pan used for cooking, or the dishes cooked inside it! But to be clear, when someone says casserole, they usually mean “baked dish”. Some of the first versions of this dish was made with rice. But now, it’s known for its use of meat, vegetables, and starchy ingredients, like potatoes, flour, or even pasta. And it’s no wonder why the dish has become a staple food, especially in the United States. Its hearty taste and filling ingredients have never failed to satisfy.

Recipe Notes

If this is your first time making a casserole, we advise that you stick to the instructions provided in this recipe. Once you’ve achieved the taste that’s up to your liking, you're free to substitute the ingredients and find alternative ways in making an improved version of this dish. 

Also, be wary of the kind of material your casserole pan is made of. This can have an effect on the time it needs to cook. Stoneware and ceramic casserole pans take longer to cook, compared to glass or metal. It’s best to check your casserole to make sure it's not overcooked or undercooked.

Commonly Asked Questions

Do you cover a casserole in the oven?

The rule of covering your casserole dish depends on the ingredients used and the recipe you’re following. While some recipes indicate so, most don’t. There’s no need to cover your cheesy steak and potato casserole for this recipe since we’re using cooked or leftover steak. Also, not covering the dish when baking gives it a golden-brown crust at the top. However, if you try other recipes that include pasta, or rice and grains, it’s important to have the pan covered during baking time.

How do I make a casserole without a casserole dish?

Not having a casserole dish shouldn’t hinder you from making this delicious meal. Instead, try substituting it with other baking dishes, such as a baking pan or an oven-safe Dutch oven, or even a sauté pan.
