How to Make Easy Tuna Noodle Casserole Recipe
Step 1: Prep Your Oven and Dish
Begin by heating your oven to 375°F (190°C) and greasing a 9×13-inch baking dish. This step ensures your casserole won’t stick and will bake evenly, creating a lovely golden crust on the bottom and sides.
Step 2: Cook the Egg Noodles
Cook your egg noodles according to the package instructions until they are perfectly al dente. Then drain them well and set aside. The noodles provide the satisfying chewiness that forms the hearty structure of this casserole, so don’t overcook!
Step 3: Combine the Ingredients
In a large bowl, mix together the drained tuna, cream of mushroom soup, milk, frozen peas, shredded cheddar cheese, sour cream, garlic powder, salt, and pepper. Stir everything until it’s fully combined and creamy. This mixture is where all flavors blend into the luscious sauce that coats every noodle.
Step 4: Add Noodles and Toss
Gently fold in the cooked egg noodles, making sure each piece is evenly coated with that delicious mixture. It’s important to be gentle here to keep the noodles intact and ensure every bite is well-seasoned.
Step 5: Layer into Your Baking Dish
Pour your noodle and tuna mixture into the greased baking dish, spreading it out evenly to prepare for baking. This sets the stage for the perfect casserole with all ingredients nestled together.
Step 6: Prepare the Topping
Mix the breadcrumbs with melted butter in a small bowl, then sprinkle this mixture evenly over the casserole. This topping is what will give your Easy Tuna Noodle Casserole Recipe that irresistible crunch and golden appeal.
Step 7: Bake to Perfection
Bake the casserole in your preheated oven for 20 to 25 minutes, or until it’s bubbling hot and the breadcrumbs have turned a beautiful shade of golden brown. This step melds all the flavors and textures, turning humble ingredients into comfort food magic.
Step 8: Rest and Garnish
Let the casserole rest for a few minutes after baking to set up nicely. If you like, sprinkle with fresh parsley to add a pop of color and a hint of fresh flavor that brightens the dish before serving.
How to Serve Easy Tuna Noodle Casserole Recipe

Garnishes
Fresh parsley or a sprinkle of grated cheddar adds a lovely visual lift and a touch of fresh herbaceousness that balances the creamy comfort of the casserole. You can also offer a squeeze of lemon on the side if you want a little brightness.
Side Dishes
A simple green salad with a tangy vinaigrette complements the richness of the casserole perfectly. Steamed or roasted vegetables like broccoli or green beans add color, fiber, and freshness for a balanced meal.
Creative Ways to Present
For a fun twist, serve the casserole in individual ramekins or small oven-safe bowls. You can even turn it into a potluck centerpiece by baking it inside a hollowed-out bread bowl for a rustic, cozy presentation that will impress your guests.
Make Ahead and Storage
Storing Leftovers
Leftover casserole can be stored in an airtight container in the refrigerator for up to 3 days. It keeps nicely, and the flavors often deepen overnight, making leftovers just as tasty as the first serving.
Freezing
This casserole freezes well and makes a fantastic meal prep option. Freeze it uncovered (once cooled), then cover tightly with foil or plastic wrap. It will keep in the freezer for up to 2 months. Thaw overnight in the fridge before reheating.
Reheating
To reheat, place the casserole in an oven-safe dish and warm it at 350°F (175°C) for 15-20 minutes until hot and bubbly. You can also microwave single servings on medium power, stirring halfway through to ensure even heating.
FAQs
Can I use fresh mushrooms instead of cream of mushroom soup?
Absolutely! Sauté fresh mushrooms with a bit of butter and mix them with a creamy béchamel sauce or cream cheese for a homemade touch. Just keep in mind this will change the texture slightly and might take a bit more time.
Is there a substitute for sour cream in this Easy Tuna Noodle Casserole Recipe?
You can swap sour cream with Greek yogurt or cream cheese if that’s what you have on hand. Both add creaminess and a slight tang without overpowering the other flavors.
Can I make this casserole gluten-free?
Yes, just substitute the egg noodles with gluten-free pasta and use gluten-free breadcrumbs or crushed gluten-free crackers for the topping. It will still be just as delicious!
How can I add more veggies to this casserole?
Feel free to toss in chopped bell peppers, diced carrots, or even a handful of spinach. Just lightly steam or sauté them first so they soften nicely in the casserole.
What’s the best cheese for this recipe?
Cheddar works beautifully for its sharpness and meltability, but you can mix in Monterey Jack or mozzarella for a different flavor profile or even add a little parmesan for some extra depth.
Final Thoughts
This Easy Tuna Noodle Casserole Recipe is pure comfort food that’s both approachable and satisfying, perfect for busy weeknights or anytime you crave something warm and cheesy. I hope you enjoy making it as much as I do, and that it becomes one of your go-to dishes for quick, delicious dinners with a nostalgic twist.
