Tuna Pasta Casserole

I made this tuna pasta casserole one evening when I was craving something cozy creamy and easy to whip up with pantry staples and I had a couple cans of tuna a half-box of pasta and some breadcrumbs ready to go so I pulled everything together in one dish and tossed it in the oven and in under an hour I had a bubbling golden-topped casserole that took me right back to childhood dinners.

There’s something incredibly comforting about the creamy sauce the tender pasta and the flaky tuna all tied together with a crispy cheesy topping and it’s simple yet so satisfying and perfect for busy nights or when you want to bring the nostalgic flavors of home-cooked meals back to the table.

Ingredients

• Here’s what I use for this recipe. You can always make substitutions if you prefer!
• Pasta – The base of the dish that carries all the creamy and savory flavors.
• Canned tuna – Mild and flaky protein that blends beautifully with the sauce.
• Cream of mushroom soup – Creates the creamy base of the casserole.
• Milk – Loosens and smooths out the sauce for a perfect texture.
• Cheddar cheese – Melts into the sauce for a bold cheesy finish.
• Mozzarella cheese – Adds creaminess and a nice melt factor.
• Onion – Brings mild sweetness and depth to the dish.
• Garlic powder – Enhances the savory flavor with a hint of spice.
• Black pepper – Adds just the right kick to balance the creaminess.
• Panko breadcrumbs – Bakes up golden and crisp on top.
• Butter – Coats the breadcrumbs and adds richness to the topping.
• Fresh parsley – Optional but brightens the flavor and adds a fresh look.

Tools You’ll Need

• Saucepan – For boiling the pasta until al dente.
• Strainer – To drain the pasta without overcooking it.
• Mixing bowl – To combine the tuna, sauce, and pasta evenly.
• Skillet – For toasting the breadcrumb topping if desired.
• Baking dish – Where everything comes together and gets golden.
• Oven mitts – Always helpful for handling a hot bubbling dish safely.

Instructions

Step 1: Cook the Pasta

I start by boiling the pasta until just al dente then I drain it and set it aside while I prepare the creamy sauce and tuna mix.

Step 2: Mix the Filling

In a large bowl I stir together the cream of mushroom soup milk drained tuna diced onion garlic powder and black pepper until everything is well combined then I fold in the cooked pasta and half of the shredded cheese.

Step 3: Transfer to Baking Dish

I spoon the tuna and pasta mixture into a greased baking dish and spread it evenly then I sprinkle the remaining cheddar and mozzarella cheeses over the top.

Step 4: Make the Breadcrumb Topping

In a small skillet I melt the butter and toss in the panko breadcrumbs until they’re coated and golden then I sprinkle them over the casserole for that perfect crispy finish.

Step 5: Bake to Perfection

I bake the casserole at 375°F for about 25 to 30 minutes until it’s hot bubbly and the cheese is melted and golden and the topping is crisp.

Step 6: Garnish and Serve

Before serving I sprinkle a little chopped parsley on top for color and freshness then I let it rest for a few minutes so it sets up just right when sliced.

Tips

You can use any short pasta shape like shells penne or rotini for this recipe. For a lighter version swap in low-fat milk and reduced-fat cheese. If you love veggies try adding frozen peas or chopped spinach to the mix. For extra flavor stir in a bit of Dijon mustard or grated Parmesan cheese into the sauce.

Ways to Serve

This tuna pasta casserole is hearty enough to stand on its own but I like to serve it with a crisp green salad or roasted vegetables on the side. It’s also excellent for leftovers and reheats beautifully in the microwave or oven. You can even freeze portions for quick lunches later in the week.
