Ingredients for best tuna noodle casserole recipe with egg noodles
Pantry staples plus a few cheesy, crispy upgrades for that nostalgic comfort food magic.
| Ingredient | Amount | Notes |
|---|---|---|
| Egg Noodles 🍝 | 2 cups | Uncooked, medium width |
| Flaked Tuna 🐟 | 2 cans | High-quality, in water |
| Cream Cheese 🧀 | 8 oz | Full-fat, softened |
| Mayonnaise 🥫 | ½ cup | Smooth, not chunky |
| Milk 🥛 | ½ cup | Whole milk preferred |
| Shredded Cheddar Cheese 🧀 | 2 cups | Medium or sharp |
| Butter 🧈 | ½ cup | Melted, unsalted |
| French Fried Onions 🧅 | ½ cup | For crispy topping |
| Garlic Powder 🧄 | 1 tsp | Freshly ground preferred |
| Onion Powder 🧅 | 1 tsp | For depth of flavor |

The tuna makes or breaks this dish—high-quality flaked tuna in water is a must. Tonno or Wild Planet are my go-tos, but any premium brand works. Egg noodles? Barilla or De Cecco are my favorites—they hold up perfectly in the oven. The cream cheese and mayo combo is what gives this casserole that ultra-creamy texture, so don't skimp on the full-fat versions. For the cheese topping, sharp cheddar gives the best flavor, but medium works too. Grab the pre-shredded kind (it's less greasy) or grate your own for extra crispiness.
No cream cheese? Sour cream works in a pinch, but it won't be quite as rich. Running low on mayo? Greek yogurt at half the amount adds tanginess. The milk keeps the sauce smooth—whole milk is ideal, but any kind will do. For the crispy topping, French fried onions are a game-changer, but crushed potato chips work too if you're in a hurry. Fresh parsley is optional but adds a pop of color—dried works if you've got it, just use a pinch. The garlic and onion powders can be swapped for fresh if you're feeling fancy, but the powdered versions are way more convenient.
This casserole tastes even better the next day—make extra and freeze half for lazy weeknights. Store leftovers in the fridge for 4-5 days, covered tightly to keep that crispy top. To reheat, cover with foil and bake at 350°F until bubbly. The cheese topping gets soggy if microwaved, so always oven-bake. For meal prep, assemble the casserole in a disposable pan—no cleanup, just bake and serve straight from the pan.

Step-by-step instructions for tuna noodle casserole
Here's how to make the ultimate cheesy, crisp-topped tuna noodle casserole that'll have everyone begging for seconds.
🍳 Step 1: Cook the Egg Noodles Al Dente
Bring a large pot of water to a rolling boil and add the 2 cups egg noodles. Cook them for 1 minute less than the package instructions suggest—they'll finish cooking in the oven. I like to test one noodle by biting into it; it should be tender but still have a slight bite. Drain the noodles and set them aside, reserving ½ cup of the pasta water. This starchy water helps create a silky sauce later.
Don't rinse the noodles—those starches are what make this casserole so creamy. If you rinse, you'll lose that magic. While the noodles cook, I usually melt the ½ cup butter in a separate small bowl so it's ready to go when we need it.
👨🍳 Step 2: Mix the Creamy Tuna Filling
In a large mixing bowl, combine the drained egg noodles with the 2 cans flaked tuna, 8 oz softened cream cheese, ½ cup mayonnaise, ½ cup milk, 2 cups shredded cheddar cheese, 1 tsp garlic powder, 1 tsp onion powder, ½ tsp salt, and ¼ tsp black pepper. Gently fold everything together with a wooden spoon until fully combined and creamy.
Here's the thing—don't overmix. You want the tuna flakes to stay distinct and visible in the final dish. If the mixture looks too thick, add 1-2 tablespoons of the reserved pasta water to loosen it. The texture should be like thick mashed potatoes but still able to hold its shape when spooned.
🥘 Step 3: Assemble in a Greased Baking Dish
Preheat your oven to 375°F while you work. Grease a 9x13-inch baking dish with butter or cooking spray—this prevents sticking and makes cleanup a breeze. Spread the tuna noodle mixture evenly into the prepared dish, pressing down gently with a spatula to create a smooth, even layer.
I like to use the back of a spoon to create some gentle swirls in the top—it makes the casserole look more appealing when it comes out of the oven. This is also when I sprinkle half of the ½ cup French fried onions over the top. The onions will get crispy during baking, adding that perfect crunchy texture we all love.
🔥 Step 4: Bake Until Bubbly and Golden
Bake the casserole uncovered for 25-30 minutes until the edges are bubbling and the top is golden brown. You'll know it's ready when the cheese has melted completely and the onions on top are crispy. If the top browns too quickly, tent it loosely with aluminum foil for the last 5-10 minutes of baking.
Don't peek too often—every time you open the oven, heat escapes and your casserole might need more time. The internal temperature should reach 165°F when checked with a meat thermometer. This ensures the tuna is fully cooked and safe to eat.
🍽️ Step 5: Top with Crispy Onions and Fresh Parsley
Remove the casserole from the oven and let it rest for 5 minutes—this allows the filling to set slightly. Sprinkle the remaining ½ cup French fried onions evenly over the top, pressing them down gently so they stick. Then scatter the ¼ cup chopped fresh parsley over everything for that fresh, vibrant finish.
Here's where the magic happens: serve immediately while the onions are still crispy and the cheese is melty. The combination of creamy tuna filling, crispy onions, and fresh parsley makes this casserole irresistible. If you have any leftovers, they actually reheat beautifully in the microwave—just cover with a damp paper towel to keep them moist.
Pro Tips For Making Best Tuna Noodle Casserole Recipe With Egg Noodles
- Drain Noodles Cold: Skip the hot water rinse—drain those egg noodles directly into an ice bath for 30 seconds. This stops the cooking process dead, keeps them from turning mushy when mixed with the creamy sauce later. I learned this the hard way after serving a watery casserole that tasted like overcooked pasta soup.
- Warm the Tuna First: Gently heat the flaked tuna in a small skillet with a splash of milk for 30 seconds before mixing it in. This melts any frozen bits and makes the texture richer—no more dry, rubbery tuna chunks in your creamy sauce. Sounds weird, but it works: the heat opens up the flakes so they absorb the mayo and cream cheese better.
- Don’t Overmix the Sauce: Stir the mayo, cream cheese, and milk together just until smooth—then fold in the noodles and tuna in two batches. Overworking the sauce makes it greasy and separates later. This isn’t the prettiest method, but it’s the tastiest: you want a creamy coating, not a heavy glaze.
- Bake Covered, Uncover Last 10: Cover the casserole with foil for the first 20 minutes to melt the cream cheese evenly, then uncover for the last 10 to let the top brown. Skipping this two-step means either a soggy top or a raw center—neither is ideal. Your future self will thank you for the even texture.
Essential equipment for this dish
Baking Dish Essentials
A 9x13-inch baking dish is your best friend for this casserole—I swear by CorningWare or Ceramic Ware for even heat distribution and easy release. If you don’t have one, a glass or metal dish works too, but avoid dark-colored pans as they can overbrown the top. For extra insurance, grease with butter or cooking spray—I always use Misto for a light, even coat. 🧈
Mixing Tools
You’ll need a large mixing bowl (I use Pyrex) for combining ingredients and a wooden spoon to gently fold everything together. Avoid metal spoons—they can break down the cream cheese too much. A spatula comes in handy for spreading the mixture evenly in the baking dish. Pro tip: Use a flexible silicone spatula to scrape every last bit from the bowl.
Oven Thermometer
Your oven’s temperature gauge might be off—always double-check with an oven thermometer (I love the Thermoworks Oven Thermometer). This ensures your casserole bakes at the perfect 375°F for that golden, crispy top. A miscalibrated oven can leave your dish undercooked or overbrowned. Trust me, it’s a game-changer for consistency. 🌡️
Cheese Tools
For the shredded cheddar, grab a box grater (like Microplane) for fresh, even shreds—pre-shredded cheese has anti-caking agents that make the topping less crispy. If you’re using French fried onions, a small bowl helps portion them evenly. And for garnishing, a pair of kitchen shears makes quick work of chopping fresh parsley.
Optional Upgrades
Want to take your casserole to the next level? A mandoline slicer (like OXO Good Grips) helps create ultra-thin French fried onion layers for extra crunch. For meal prep, a disposable aluminum pan saves cleanup—just bake, serve, and toss. And if you’re feeling fancy, a mini food processor blends the cream cheese and mayo into a silky base in seconds. 💡

Frequently asked questions
Can I use frozen egg noodles instead of fresh?
Frozen egg noodles work perfectly—just cook them 1 minute less than the package suggests since they'll finish in the oven. Thaw them first in warm water for 2-3 minutes to speed up cooking. The texture difference is minimal, but frozen noodles absorb sauce slightly better for extra creaminess.
How do I make this casserole without mayo?
Swap the mayo for ½ cup Greek yogurt or ¼ cup sour cream—both add tanginess and creaminess. For richness, mix in 2 tablespoons melted butter with the yogurt. The texture will be slightly lighter but still delicious. If you're avoiding dairy completely, use ¼ cup unsweetened applesauce for moisture.
Why did my casserole turn out soggy?
Sogginess usually happens from one of three things: overcooking the noodles, not draining them well, or opening the oven too often. Always cook noodles 1 minute less than package instructions and drain thoroughly. Press the mixture down firmly in the dish and avoid peeking at it while baking—every time you open the oven, heat escapes and can make the top steam instead of crisp.
Can I add vegetables to this recipe?
Yes! Try adding ½ cup frozen peas and carrots (thawed) or diced zucchini for extra veggies. For heartier texture, mix in ½ cup chopped celery or mushrooms
How long can I keep leftovers in the fridge?
Store leftovers in an airtight container for 4-5 days in the fridge. The crispy topping will soften slightly, but reheating in the oven at 350°F for 10-15 minutes restores that golden crunch. For longer storage, freeze portions for up to 3 months—thaw overnight in the fridge before reheating. Never microwave without covering with a damp paper towel to prevent drying.
