Ingredients You’ll Need
This Easy Tuna Casserole comes together with simple pantry staples and a few fresh touches. Each ingredient plays a starring role, whether providing creaminess, layers of savory flavor, or a pop of color and crunch. Here’s what you’ll need and why each one matters:
- Egg noodles (2 cups, uncooked): Wide, tender egg noodles perfectly soak up all the creamy goodness without losing their shape.
- Cream of mushroom soup (1 can, 10.5 oz): Acts as the rich, savory base that binds everything together; feel free to sub cream of celery or chicken for a twist.
- Milk (½ cup): Thins out the soup just enough to coat the noodles, adding extra silkiness.
- Frozen peas (1 cup): Bring pops of sweetness and a burst of green, balancing the richness of the casserole.
- Tuna (1 can, 12 oz, drained and flaked): The star protein; wild-caught or solid white albacore gives excellent flavor.
- Shredded cheddar cheese (1 cup): Adds gooey melt and sharpness with every bite—don’t skimp on this!
- Garlic powder (½ teaspoon): Boosts overall savory depth without overpowering.
- Onion powder (½ teaspoon): Underlines all the comforting flavors with a mild and sweet undertone.
- Salt and pepper (to taste): Essential for seasoning and making the flavors pop.
- Crushed butter crackers or breadcrumbs (1 cup): They provide that essential golden crunch on top; buttery crackers will taste extra decadent.
- Melted butter (2 tablespoons): Needed for tossing with the topping to ensure perfect browning and flavor.
How to Make Easy Tuna Casserole
Step 1: Get Set Up
Preheat your oven to 375°F and grease a 9×13-inch baking dish. Taking a moment to prep your baking dish ensures the casserole lifts out easily—and prevents any precious cheesy bits from sticking.
Step 2: Cook the Egg Noodles
Bring a pot of salted water to a boil and cook your egg noodles according to package instructions until just al dente. Remember, the noodles will keep cooking in the oven, so don’t let them go mushy. Drain them well and set aside.
Step 3: Mix the Creamy Base
In a large mixing bowl, stir together the cream of mushroom soup, milk, frozen peas, drained tuna, shredded cheddar cheese, garlic powder, onion powder, salt, and pepper. This is where the magic starts—every ingredient partners up to make a sauce that’s rich, flavorful, and totally inviting.
Step 4: Combine With Noodles
Gently fold the cooked egg noodles into the creamy mixture until everything is evenly coated. Take your time here, ensuring the tuna and peas are distributed throughout for the perfect bite every time.
Step 5: Assemble the Casserole
Pour the noodle mixture into your prepared baking dish, smoothing it into an even layer. This will help the casserole bake uniformly and look extra inviting straight from the oven.
Step 6: Add the Crunchy Topping
In a small bowl, toss the crushed butter crackers or breadcrumbs with the melted butter. Sprinkle this mixture generously over the top of your casserole. This is what gives Easy Tuna Casserole its irresistible golden crunch!
Step 7: Bake to Perfection
Slide the dish into the oven and bake uncovered for 25 to 30 minutes. You’ll know it’s ready when the topping turns golden and the filling is bubbling around the edges. Let it cool for a few minutes before serving so each square keeps its shape.
How to Serve Easy Tuna Casserole

Garnishes
Give your Easy Tuna Casserole a finishing touch with a sprinkle of chopped fresh parsley or chives—the bright green lifts the dish visually and adds a hint of freshness. For an extra burst of flavor, a light dusting of paprika or a few turns of cracked black pepper can be just the thing.
Side Dishes
This cozy casserole pairs perfectly with a crisp green salad or a platter of steamed broccoli to add some crunch and color. For a nostalgic dinner, serve with a slice of buttered toast or warm dinner rolls on the side to soak up every last bit of sauce.
Creative Ways to Present
To make Easy Tuna Casserole the star of your table, consider baking it in individual ramekins for personalized servings. Or, serve with a wedge of lemon on each plate to squeeze over the top—a fresh citrus note really brings the flavors alive!
Make Ahead and Storage
Storing Leftovers
Leftover Easy Tuna Casserole keeps beautifully in the fridge. Just cover the baking dish tightly or transfer portions to an airtight container. It stays fresh for up to 3 days, making it a dream for meal prep or quick lunches.
Freezing
This casserole freezes like a champ! Let it cool fully, then wrap tightly with plastic wrap and foil, or portion into containers. For best quality, eat within 2 months. Thaw overnight in the fridge before reheating for a just-baked experience.
Reheating
To reheat, simply cover the dish with foil and warm in a 350°F oven for about 20 minutes, or until hot and bubbly. Individual servings can be microwaved in a pinch—just add a splash of milk to keep things creamy.
