How to Make Easy Tuna Noodle Casserole
Step 1: Cook the Egg Noodles
Start by bringing a big pot of salted water to a boil. Cook the egg noodles according to the package directions until they’re just al dente—think tender with a little firmness left. Drain them well and set aside. The noodles will soak up more flavor as they bake, so don’t overcook them now!
Step 2: Sauté the Onions and Garlic
In a large skillet, melt your butter over medium heat. Toss in the chopped onion and sauté for about 4 to 5 minutes until it’s soft and translucent but not browned. Stir in the minced garlic for another quick 30 seconds, until fragrant. Your kitchen will smell amazing already!
Step 3: Combine the Casserole Filling
Grab a very large mixing bowl. Add the cooked noodles, sautéed onions and garlic, drained tuna, cream of mushroom soup, sour cream, milk, thawed peas, salt, pepper, and half of the shredded cheddar cheese. Mix everything together until all the noodles and tuna are coated evenly with that dreamy, creamy sauce. You want every bite to have a bit of everything.
Step 4: Assemble the Easy Tuna Noodle Casserole
Spread a bit of oil or butter in a 9×13-inch baking dish to keep things from sticking. Pour the noodle mixture in and gently smooth out the top with a spatula. Sprinkle the rest of the cheddar cheese all over—it’ll melt into a golden, bubbly blanket during baking.
Step 5: Add the Crunchy Topping
In a small bowl, mix the breadcrumbs with olive oil or melted butter, tossing until they’re moist and slightly clumpy. Evenly scatter this mixture across the casserole for that classic crispy finish. Don’t skip it—this textural contrast is irresistible!
Step 6: Bake to Perfection
Bake the casserole uncovered at 375°F (190°C) for 25 to 30 minutes. When you peek inside, the top should be sizzling, bubbly around the edges, and gloriously golden. Let it rest a few minutes before scooping, so the sauce thickens and each serving holds together beautifully.
How to Serve Easy Tuna Noodle Casserole

Garnishes
Give your Easy Tuna Noodle Casserole a sprinkle of freshly chopped parsley or snipped chives right before serving. Not only does it add a touch of color, but those fresh herbs bring a welcome pop of brightness that lifts each creamy, savory bite.
Side Dishes
This casserole pairs beautifully with a crisp green salad or some simply steamed veggies like broccoli or green beans. A loaf of warm, crusty bread is perfect for soaking up any leftover sauce on your plate—trust me, you won’t want to leave a drop behind!
Creative Ways to Present
Try spooning portions into individual ramekins for a dinner party spin, or bake it in a round casserole dish for a retro potluck vibe. If you’re serving a crowd, scatter some crushed potato chips or Ritz crackers on top in place of breadcrumbs for a fun, extra-crunchy twist that takes Easy Tuna Noodle Casserole over the top.
Make Ahead and Storage
Storing Leftovers
Leftover Easy Tuna Noodle Casserole keeps well covered in the refrigerator for up to 3 days. Just pop the cooled dish into an airtight container or wrap it tightly in foil before stashing it in the fridge—you’ll have a comforting meal ready in minutes whenever hunger calls.
Freezing
If you want to make your casserole ahead (or have lots of leftovers), freeze individual portions or the whole thing. Wrap tightly with a double layer of foil or use freezer-safe containers. It’ll keep well for up to 2 months. To cook from frozen, add about 10 extra minutes to your baking time, or thaw overnight in the fridge for best results.
Reheating
To bring Easy Tuna Noodle Casserole back to its gooey, creamy best, reheat covered in the oven at 350°F until hot throughout. For smaller servings, the microwave works just fine—try adding a splash of milk to keep things from drying out. If your topping needs refreshing, pop it under the broiler for a minute or two for a crisp finish.
FAQs
Can I use a different type Main Course
Absolutely! While egg noodles are classic for Easy Tuna Noodle Casserole, you can substitute with rotini, penne, or any short pasta you have on hand. Just aim to cook all pasta varieties al dente so they hold up during baking.
