🍴 Recipe Tips
I've made this mac and cheese with tuna recipe a few times and something we cannot decide upon is whether or not we enjoy it more with or without the canned mushroom soup. Honestly, it tastes great either way but trying it for yourself is the only way to decide which is better.
If you think you would prefer to use canned peas instead of frozen, then simply drain and rinse the peas before use. Add them in at the end, just before serving.
We also really enjoy our tuna noodles with a crushed Ritz cracker crumb topping, so if you're looking for a great way to serve up your stovetop tuna casserole give it a try and see how you like it! 🙂
We've tried this Mac N Cheese Tuna Casserole with different brands and types of macaroni and cheese including Kraft, store brands, "creamy" versions, and shells or shapes. Depending on the different macaroni you use, the flavor and textures change slightly. That said, you really can't go wrong if you use your favorites!
Traditionally, tuna noodle is a dish with noodles, cheese, cream of soups, tuna, and a veggie (usually peas) the toppings (if any) can vary from crushed potato chips to breadcrumbs. This dish is very simple with boxed macaroni and cheese, tuna, cream of mushroom, peas, and onion.
I usually serve the dish alone as-is but sometimes I enjoy serving it up with more veggies like a simple green garden salad or steamed broccoli. Sticking with this that tastes great with cheddar cheese is a pretty safe bet for getting a good tasting meal on your plate.
To heat this dish you can simply place a serving on a plate in the microwave for 1-2 minutes or you can reheat it on the stovetop. To avoid it drying out consider adding a tablespoon of butter or a dash of milk to keep the mix hydrated.
