Recipe notes and tips

When it comes to any recipe, it is always a good idea to understand what notes and tips you can use to help you fully utilize the recipe and have success each and every time. If you want to make the most out of this delicious cheesy tuna casserole then here are some recipe notes and tips to help.

  • You can make your own macaroni cheese instead of using the packets. You will need all-purpose flour, extra milk, melted butter, and extra cheese to make the creamy sauce. There are plenty of recipes online.

Variations to try

Like with a lot of recipes, once you have tried them out a few times you can look to make some changes and vary the recipe to suit your tastes and preferences. So I wanted to share with you some of them that you might want to try. 

  • You can use different canned soups if you are not keen on mushrooms. Cream of chicken soup is a great option. 
  • Instead of potato chips, you could use crushed ritz crackers instead. The extra cheesy flavor will be really enjoyable. 
  • As casserole recipes go, you can be experimental. You could use this easy recipe as a base for all sorts of ingredients. Chicken, ham, or cooked meats from another meal will all work well. 
  • Add some extra vegetables to this dish. Green onions or things like frozen peas and green beans will taste great. It will affect the overall cost of the meal, but it is added nutrition. 
  • Use pantry staples to add to the flavor. Paprika or nutmeg will be great flavors.

How do I store the Cheesy Tuna Casserole?

If you have any leftovers for the next day then you can easily store them in the refrigerator. Let them cool completely and then put them into an airtight container. Store in the refrigerator for up to three days. You can heat them up in the microwave or the oven. You could also batch-cook this and freeze a portion for when you have a busy night. The frozen casserole will last up to two months in the freezer. 

Can you make this Vegetarian?

Sure! The tuna has a great flavor but you don’t need to use it if you want to keep this a veggie meal. You could add lots of vegetables to it instead. Zucchini, Eggplant, Bell Peppers, and a variety of mushrooms will all work well. This is also a good recipe to use up any vegetables you have in the refrigerator.
