How to Make Tuna Casserole Recipe
Step 1: Prep the Oven and Pan
Begin by preheating your oven to 375°F for a perfectly baked finish. Lightly grease a 9×13-inch baking dish so nothing sticks and cleanup is a breeze. This step sets the stage for an effortless assembly later on.
Step 2: Cook the Egg Noodles
Bring a large pot of salted water to a boil and cook the egg noodles just until al dente, following your package’s directions. Once they’re ready, drain them well — you want them moist but not soggy, since they’ll soak up sauce in the casserole.
Step 3: Sauté the Aromatics
In a large skillet over medium heat, melt your butter. Add in the chopped onion and sauté until it becomes translucent and tender, about 4 to 5 minutes. Stir in the garlic and let it cook for another 30 seconds, just until fragrant. At this point, your kitchen should already smell mouthwateringly good!
Step 4: Make the Creamy Base
Add the cream of mushroom soup, milk, and sour cream straight into the skillet with your onions and garlic. Stir it all together until you have a silky, uniform sauce — this creamy mixture is what makes this Tuna Casserole Recipe so luxuriously delicious.
Step 5: Add the Veggies, Tuna, and Cheese
Toss in the frozen peas for bursts of color, followed by the drained, flaked tuna. Sprinkle in half of the shredded cheddar cheese for a melty, flavorful touch throughout the casserole. Season the sauce with salt and pepper to taste, and give everything a thorough mix to ensure even distribution of all the tasty bits.
Step 6: Combine with Noodles
Add your cooked egg noodles to the creamy skillet mixture. Gently fold the noodles in until they’re coated with that glorious sauce and well mixed. This is where all those familiar, delicious casserole flavors come together!
Step 7: Assemble and Top
Pour the combined mixture into your prepared baking dish and spread it out evenly. Scatter the remaining cheddar cheese over the top, then finish with a generous layer of crushed crackers or breadcrumbs for a crunchy, golden crust.
Step 8: Bake and Finish
Bake the casserole uncovered for 20 to 25 minutes, until the top is bubbling and beautifully golden brown. Let it rest for about 5 minutes before scooping out generous servings. Top with chopped parsley if you’d like a fresh, colorful touch!
How to Serve Tuna Casserole Recipe

Garnishes
Bringing your Tuna Casserole Recipe to the table with a sprinkle of chopped fresh parsley or a dusting of extra cheddar on top can make all the difference. It adds brightness and signals that something special is about to be enjoyed. A wedge of lemon on the side is lovely too, for a fresh squeeze and zing.
Side Dishes
Round out your meal with a crisp green salad, maybe tossed with a zippy vinaigrette, or some perfectly roasted green beans or broccoli. Warm crusty bread, homemade garlic toast, or even a simple carrot slaw can complement your casserole wonderfully without stealing the spotlight.
Creative Ways to Present
Portion your Tuna Casserole Recipe into individual ramekins for personalized servings — they’re great for entertaining or making weeknight dinners feel just a touch more special. You can also cut the cooled casserole into neat squares for packed lunches, or even scoop it over baked potatoes for a fun twist.
Make Ahead and Storage
Storing Leftovers
Any leftover Tuna Casserole Recipe can be covered and stored in the refrigerator for up to three days. Individual portions can be kept in airtight containers, making it easy to reheat and enjoy for quick lunches or dinners all week.
Freezing
This casserole is a freezer-friendly dream! Let it cool completely, then wrap your dish tightly or transfer to freezer-safe containers. It will keep well for up to two months. Thaw overnight in the fridge before reheating for best results.
Reheating
Reheat the Tuna Casserole Recipe in a 350°F oven (covered with foil to prevent over-browning) until it’s heated through and bubbly. You can also microwave individual portions, but a quick oven blast helps the topping regain its crunch.
FAQs
Can I use a different type Main Course
Absolutely! While egg noodles are traditional in a Tuna Casserole Recipe, you can substitute rotini, penne, or even whole wheat pasta for a similar result. Just make sure to cook the noodles al dente so they don’t get soggy during baking.
What can I use instead of cream of mushroom soup?
If mushrooms aren’t your favorite, try cream of celery or cream of chicken soup for a subtle twist on the original Tuna Casserole Recipe. You can even make a homemade white sauce if you’d like to keep things extra fresh and customizable.
How do I make the topping extra crispy?
Mix your breadcrumbs or cracker crumbs with a tablespoon of melted butter before sprinkling over the top. This gives them even more crunch and golden color once baked, turning the topping into something truly crave-worthy.
Can I add other vegetables?
Definitely! Feel free to stir in cooked mushrooms, diced bell peppers, or steamed broccoli florets. The Tuna Casserole Recipe is a wonderful base for sneaking in extra veggies the whole family will love.
Is this casserole good for meal prep?
Yes, it’s perfect for meal prepping! You can assemble everything ahead of time, store it unbaked in the fridge, and pop it in the oven when you’re ready. Leftovers reheat well, making it a smart choice for busy schedules.
