Step‑by‑Step Instructions for Sheet Pan Tuna Noodle Casserole

Step 1: Preheat and Prep the Pan
Begin by preheating your oven to 400°F (200°C) to get it nice and hot for the Sheet Pan Tuna Noodle Casserole. While it’s warming up, take a large sheet pan and generously grease it with butter or nonstick spray to prevent sticking once your casserole is baked.

Step 2: Mix the Casserole Ingredients
In a large mixing bowl, combine the cooked egg noodles, drained canned tuna, cream of mushroom soup, and milk. Also, add in the frozen peas and half of your shredded cheddar cheese. Use a spatula to gently fold all the ingredients together until they form a creamy and uniform mixture.

Step 3: Spread the Mixture on the Sheet Pan
Once your casserole mixture is well combined, spread it evenly across the prepared sheet pan. Use a spatula to smooth out the top, ensuring the mixture is distributed evenly so that every bite of your Sheet Pan Tuna Noodle Casserole has a consistent texture and flavor.

Step 4: Add Toppings
Sprinkle the remaining shredded cheddar cheese over the top of the casserole for an extra cheesy finish. Then, generously add crushed potato chips on top for that delightful crunch. These toppings will create a beautiful golden crust during baking, enhancing the overall appeal of your dish.

Step 5: Bake to Perfection
Place the prepared sheet pan into the preheated oven and bake for 20 to 25 minutes. Keep an eye on it, and you’ll know it’s ready when the edges are bubbling and the top is a lovely golden brown. This visual cue ensures your Sheet Pan Tuna Noodle Casserole is both delicious and perfectly cooked.

Sheet Pan Tuna Noodle Casserole Recipe FAQs

What should I look for in ripe ingredients for this casserole?
Absolutely! For the best flavors, ensure your egg noodles are cooked al dente, so they retain a bit of bite. When choosing canned tuna, opt for good quality, packed in water or oil, and make sure it’s well-drained. If you can, check the cream of mushroom soup overall consistency and freshness; it should be smooth and not past its expiration date for optimal taste.

How long can I store leftovers from the casserole?
Very! Your leftover Sheet Pan Tuna Noodle Casserole can be stored in an airtight container in the refrigerator for up to 3 days. Just remember to reheat it in the oven to retain that lovely texture, covered with foil to keep it moist.

Can I freeze the casserole, and how should I do it?
Yes, you can! To freeze the casserole, let it cool completely, then transfer it to a tightly sealed container or a freezer-safe bag. It will keep well in the freezer for up to 2 months. When you’re ready to enjoy it again, thaw it overnight in the fridge and then reheat in the oven.

What are the common troubleshooting tips if my casserole turns out dry?
If your casserole ends up dry, it could be due to overbaking or not mixing the ingredients thoroughly. To remedy this, ensure that you mix thoroughly to coat everything evenly and keep a close eye on the oven during the last minutes of baking. If storing it in advance, adding a splash of milk before baking can help keep it moist.

Are there any dietary considerations I should keep in mind?
Definitely! If you’re catering to gluten-free diets, make sure to use gluten-free pasta and check that the cream of mushroom soup is labeled gluten-free too. For those with allergies, be cautious with ingredients like dairy and ensure your tuna is from a reliable source to avoid contamination.

Can I adapt this recipe for my pets?
While it’s tempting, I wouldn’t recommend sharing this casserole with pets, especially the cheese and creamy soup. They can often have sensitivities to dairy and rich foods. Stick to plain canned tuna, without any spices, instead, if you want to treat them!
