Ingredients for the Best Tuna Casserole

This tuna casserole comes together with just a handful of simple ingredients, most of which you probably already have in your kitchen. Here’s what you’ll need:

• 2 cans (5 oz each) tuna, drained – I prefer chunk light tuna in water, but use what you like!
• 2 cups cooked egg noodles – Cook them just until al dente so they don’t get mushy in the oven.
• 1 can (10.5 oz) condensed cream of mushroom soup – The secret to that creamy, rich sauce.
• 1/2 cup milk – Whole milk works best, but any kind will do.
• 1/2 cup frozen peas – No need to thaw them first—they’ll cook right in the casserole.
• 1/2 cup shredded cheddar cheese – Sharp cheddar adds a nice tang, but any cheese works.
• 1/4 cup breadcrumbs – Plain or seasoned, either is fine.
• 1 tbsp butter, melted – This gives the breadcrumb topping that golden crunch.
• 1/2 tsp salt – Adjust to taste, especially if your tuna is already salted.
• 1/4 tsp black pepper – Freshly ground is best for extra flavor.

That’s it! Simple, right? Now, let’s get baking.

How to Make the Best Tuna Casserole

Okay, let’s get cooking! This tuna casserole comes together so easily – you’ll be amazed how quickly dinner’s ready. Here’s exactly how I make it:

1. Preheat your oven to 375°F (190°C). Don’t skip this step! Starting with a hot oven ensures that perfect golden crust.
2. Mix everything except the breadcrumbs in a large bowl. I like to gently fold the tuna, noodles, soup, milk, peas, cheese, salt and pepper together until everything’s evenly coated in that creamy mushroom sauce. Don’t overmix though – we want to keep those noodles intact!
3. Transfer to a greased baking dish. A 2-quart casserole dish works perfectly here. Spread the mixture evenly so it bakes uniformly.
4. Make the breadcrumb topping (see below for details). This crispy golden crown is what takes this casserole from good to amazing!
5. Bake for 20-25 minutes until the top is beautifully golden brown and the edges are bubbling. That bubbling is your cue it’s ready – the sauce thickens perfectly as it bakes.

Pro tip: Let it rest for 5 minutes after baking. This helps the sauce set up nicely so it’s creamy, not runny.

Preparing the Breadcrumb Topping

This topping is seriously magical – it adds the perfect crunch to every bite. Here’s how I do it:

Simply mix 1/4 cup breadcrumbs with 1 tablespoon melted butter in a small bowl. I use my fingers to really work the butter into the crumbs until they look like wet sand. Then sprinkle it evenly over the casserole – don’t clump it all in one spot!

The butter helps the crumbs toast up beautifully in the oven. You’ll know it’s perfect when the topping turns that gorgeous golden brown and smells slightly nutty. That crisp texture against the creamy noodles underneath? Absolute perfection!

Tips for the Best Tuna Casserole

After making this casserole countless times, I’ve picked up some tricks that make it even better:

• Swap the peas – Try broccoli florets or diced carrots for a veggie twist
• Fresh herbs make magic – Stir in chopped parsley or dill before baking
• Double the recipe – It reheats beautifully for easy lunches all week
• Crispier topping? – Broil for 1-2 minutes at the end (watch closely!)
• No egg noodles? – Shells or rotini work great too

My biggest tip? Taste the filling before baking and adjust seasonings – every tuna brand varies!

Variations of the Best Tuna Casserole

One of my favorite things about this recipe is how easily you can mix it up! Here are some delicious twists I’ve tried (and loved) over the years:

• Mushroom lovers: Sauté 1/2 cup sliced mushrooms with a pat of butter until golden, then mix them right into the casserole. They add such a meaty texture!
• Cheese swap: Try Swiss or pepper jack instead of cheddar for a fun flavor change. I sometimes do half cheddar, half mozzarella for extra gooeyness.
• Gluten-free: Use your favorite GF noodles and gluten-free breadcrumbs – it works perfectly! Just check your soup label too.
• Extra protein: Stir in a handful of cooked, chopped bacon or diced ham for a heartier version.
• Creamier sauce: Add an extra 1/4 cup sour cream to the filling mixture – so rich and delicious!

The beauty is, once you’ve got the basic method down, you can really make it your own. What variations will you try first?

Serving Suggestions for the Best Tuna Casserole

Oh, the possibilities! While this tuna casserole is absolutely delicious all on its own, I love rounding out the meal with a few simple sides. Here’s how I usually serve it up:

A crisp green salad is my go-to pairing – the fresh crunch balances the creamy casserole perfectly. I’ll toss together some romaine with cherry tomatoes, cucumber slices, and maybe some shredded carrots (because why not keep the carrot theme going?). A simple vinaigrette ties it all together without overpowering the main dish.

On extra hungry nights, garlic bread makes everything better. Just slice a baguette, spread with garlic butter, and toast until golden. The buttery, garlicky flavors complement the tuna casserole beautifully – plus it’s perfect for scooping up any saucy bits left in the dish!

For a lighter option, try steamed green beans or roasted asparagus. Their bright flavors cut through the richness of the casserole. And if you’re feeding a crowd? Double the recipe and serve with both salad and bread – everyone will leave happy!

Storage and Reheating Instructions

Here’s the beautiful thing about this tuna casserole—it tastes just as good (maybe even better!) the next day. I always make extra because the leftovers are gold. But you’ve got to store and reheat it right to keep that perfect texture.

Storing in the fridge: Let the casserole cool completely first—about 30 minutes should do it. Then cover tightly with foil or transfer to an airtight container. It’ll keep beautifully for 3 days in the fridge. The flavors actually meld together and deepen overnight, making lunch the next day something to look forward to!

Reheating in the oven: This is my preferred method—it keeps the topping crispy. Preheat to 350°F (175°C), remove the foil (if stored with it), and bake for 15-20 minutes until heated through. If the top starts getting too dark, just lay a piece of foil loosely over it. You’ll know it’s ready when you see those little bubbles around the edges again.

Microwave option: When you’re in a hurry, scoop a portion into a microwave-safe dish and cover with a damp paper towel. Heat in 30-second bursts, stirring between each. The paper towel helps prevent that dreaded sogginess. It won’t be quite as crisp as oven-reheated, but still delicious!

Pro tip: If the sauce seems thick after refrigeration, stir in a teaspoon of milk before reheating to bring back that creamy texture. And whatever you do, don’t freeze it—the noodles turn mushy and the sauce separates. Trust me, I learned that one the hard way!

Nutritional Information for the Best Tuna Casserole

Now, I’m no nutritionist, but I do like knowing what’s going into my family’s meals! These numbers are estimates based on the exact ingredients I use—your mileage may vary depending on brands and any tweaks you make. But here’s the general breakdown per serving (about 1/4 of the casserole):

• Calories: Around 320 – Not bad for such a satisfying meal!
• Protein: 22g – Thanks to all that tuna and cheese
• Carbs: 30g – Mostly from those comforting egg noodles
• Fiber: 3g – The peas help bump this up
• Sugar: Just 3g – Mostly from the natural milk sugars
• Fat: 12g – The cheese and butter do their thing

A few notes from my kitchen experiments: Using whole wheat noodles adds about 2g more fiber per serving. Skim milk instead of whole drops the fat by about 2g. And if you’re watching sodium, look for low-sodium tuna and soup—that can cut the sodium nearly in half!

Remember, this is comfort food meant to be enjoyed! I figure the protein-packed tuna balances out the creamy goodness. And honestly? When my kids clean their plates (which they always do with this casserole), that’s nutrition enough for me!

Frequently Asked Questions

Can I use fresh tuna instead of canned?
Absolutely! Simply bake or poach about 10 oz of fresh tuna until flaky, then use just like canned. The texture will be slightly meatier, and the flavor more delicate. I’ve done this when I’ve had leftover grilled tuna—works like a charm!

Can I freeze leftovers?
I don’t recommend it, unfortunately. The noodles turn mushy and the sauce separates when thawed. Trust me—I’ve ruined perfectly good leftovers trying! Instead, store in the fridge and enjoy within 3 days.

How can I make it creamier?
Easy fixes! Stir in an extra 1/4 cup milk before baking, or mix in 2 tbsp sour cream or cream cheese with the filling. My secret? A sprinkle of grated Parmesan melts right into the sauce for extra richness.

Can I make this ahead?
You bet! Assemble the casserole (without baking) up to a day in advance. Just cover and refrigerate, then add 5-10 minutes to the baking time since it’ll be cold from the fridge. The breadcrumbs might get slightly softer, but still delicious!

Why is my casserole watery?
Usually means the noodles were overcooked or the tuna wasn’t drained well. Next time, cook noodles al dente and really press that tuna dry. If it happens, just pop it back in the oven uncovered for 5-10 more minutes.
