• 1 can (10.5 ounces) condensed cream of mushroom soup
• 2 cups milk

• Shredded cheddar cheese
• Mozzarella cheese
• Parmesan cheese
• Frozen peas
• Sweet corn
• Chopped celery
• Diced onion
• Garlic powder
• Black pepper
• Paprika
• Fresh parsley
• Crushed buttery crackers

These additions can elevate the casserole while keeping the preparation easy.

Kitchen Equipment

You’ll need:

• 9×13-inch glass baking dish
• Large mixing bowl
• Measuring cups
• Wooden spoon
• Aluminum foil
• Serving spoon

Step 1: Preheat the Oven

Preheat your oven to 350°F (175°C).

Lightly grease your baking dish with cooking spray or butter to prevent sticking.

Step 2: Add the Egg Noodles

Spread the uncooked egg noodles evenly across the bottom of the baking dish.

There’s no need to boil them first.

During baking, they’ll absorb the creamy liquid and cook to tender perfection.

Step 3: Add the Tuna

Open the tuna cans and pour the contents directly over the noodles.

Do not drain the liquid.

The flavorful liquid becomes part of the cooking sauce and helps hydrate the noodles.

Break up larger chunks slightly with a fork, leaving some larger pieces for texture.

Step 4: Prepare the Sauce

In a mixing bowl, whisk together:

• Cream of mushroom soup
• Milk

Stir until completely smooth.

The mixture should be creamy and free of lumps.

Step 5: Pour Over the Casserole

Carefully pour the soup mixture evenly over the noodles and tuna.

Use a spoon to gently press the noodles beneath the liquid as much as possible.

This ensures even cooking throughout the casserole.

Step 6: Cover and Bake

Cover the baking dish tightly with aluminum foil.

Bake for approximately 45 minutes.

The foil traps moisture, allowing the noodles to soften without drying out.

Step 7: Stir and Finish Baking

Remove the foil.

Gently stir the casserole to redistribute the sauce and noodles.

Return it to the oven uncovered for another 15 to 20 minutes, or until the noodles are tender and the top begins to turn lightly golden.

If adding cheese, sprinkle it over the top during the final 10 minutes of baking.

Step 8: Rest Before Serving

Allow the casserole to rest for about 10 minutes after removing it from the oven.

This gives the sauce time to thicken, making it easier to serve while enhancing the overall texture.

Helpful Tips for Success

Don’t Drain the Tuna

The liquid from the canned tuna provides extra flavor and helps cook the noodles evenly.

Cover Tightly

A tightly covered baking dish traps steam, ensuring the noodles become tender instead of drying out.

Stir Halfway Through

One gentle stir during baking helps distribute moisture evenly throughout the casserole.

Add Cheese at the End

Adding cheese near the end keeps it creamy while allowing the top to brown beautifully.

Let It Rest

Resting the casserole before serving allows the sauce to thicken into a rich, creamy consistency.

Easy Variations

Cheesy Tuna Casserole

Mix one to two cups of shredded cheddar into the sauce before baking.

Vegetable Version

Add frozen peas, carrots, broccoli, or corn for extra nutrition and color.

Garlic Parmesan Style

Season with garlic powder and top with grated Parmesan before the final bake.

Crunchy Topping

Sprinkle crushed buttery crackers or seasoned breadcrumbs mixed with melted butter over the casserole before the final baking period.

Spicy Version

Add crushed red pepper flakes or diced jalapeños for a little heat.

Mushroom Lovers’ Casserole

Mix in fresh sautéed mushrooms for even richer flavor.

Serving Suggestions

This creamy tuna noodle casserole is hearty enough to stand on its own, but pairing it with the right side dishes can turn it into a complete and satisfying meal. Its rich, comforting flavors go wonderfully with fresh vegetables, crisp salads, or warm homemade bread.

Some delicious serving ideas include:

• Fresh green salad with a light vinaigrette
• Steamed broccoli
• Roasted asparagus
• Green beans with butter
• Honey-glazed carrots
• Garlic bread
• Dinner rolls
• Biscuits
• Coleslaw
• Caesar salad
• Sautéed spinach
• Roasted Brussels sprouts

For a heartier meal, serve the casserole alongside roasted potatoes or a bowl of homemade vegetable soup.

A sprinkle of fresh parsley, chopped chives, or a little grated Parmesan cheese just before serving adds color and an extra burst of flavor.

Storage Instructions

One of the best things about this casserole is how well it stores, making it ideal for meal prepping or enjoying as leftovers.

Allow the casserole to cool completely before transferring it to an airtight container.

Store in the refrigerator for up to 4 days.

If you’d like to freeze it, portion the casserole into freezer-safe containers and freeze for up to 3 months.

Label each container with the date so you’ll know when it was prepared.

Reheating Instructions

Oven

Place the casserole in an oven-safe dish.

Cover loosely with foil and bake at 325°F (165°C) for about 20 minutes or until heated through.

If the casserole seems dry, stir in a splash of milk before reheating.

Microwave

Transfer an individual serving to a microwave-safe bowl.

Add a tablespoon or two of milk if needed, then microwave in 30-second intervals, stirring between each until hot.

Stovetop

Place leftovers in a skillet over low heat.

Add a small amount of milk and stir gently until warmed through.

Common Mistakes to Avoid

Although this recipe is incredibly simple, avoiding a few common mistakes will ensure perfect results every time.

Draining the Tuna

The liquid inside the canned tuna is an important part of the recipe.

It helps provide moisture while adding flavor during baking.

Forgetting to Cover the Dish

Covering the casserole during the first stage of baking traps steam, allowing the noodles to cook properly.

Not Using Enough Liquid

The noodles absorb a surprising amount of moisture.

If your casserole appears dry before baking, add a small splash of extra milk.

Overbaking

Cooking too long after removing the foil can cause the noodles to become overly soft.

Watch the casserole during the final baking stage.

Skipping the Rest Time

Allowing the casserole to sit for about 10 minutes before serving helps the creamy sauce thicken beautifully.
