Creamy Tuna Noodle Casserole is a classic comfort food that combines tender noodles, flaky tuna, and a rich, creamy sauce all baked to bubbly perfection. It usually has a bit of crunch on top, thanks to breadcrumbs or crushed crackers, making every bite satisfying and nostalgic. This dish is simple but so full of flavor, with just the right balance of creamy and savory that feels like a warm hug on a plate.
I love making this casserole when I want something easy but filling, especially on busy weeknights. It’s one of those recipes that everyone seems to enjoy, no matter their age, and usually disappears quickly from the table. I find that stirring in some peas or a little cheese adds a nice twist and makes it even tastier. Plus, it’s great for using canned tuna and pantry staples, which makes it an easy weekday go-to in my kitchen.
My favorite way to serve this is straight from the oven, with a side of simple green salad or steamed veggies to keep things fresh. It’s the kind of meal that brings back memories of family dinners and cozy nights, so I always feel comforted making it. If you’re ever in need of a straightforward, tasty dish that doesn’t take too much effort, this creamy tuna noodle casserole is a great choice to keep on hand.
Key Ingredients & Substitutions
Egg Noodles: These noodles hold the creamy sauce well. You can swap them for rotini, fusilli, or even macaroni if preferred.
Tuna: Look for canned tuna in water for a lighter taste. If you want richer flavor, try tuna in oil or use canned salmon.
Cheese: Sharp cheddar adds a nice tang. Feel free to mix in mozzarella or Monterey Jack for a creamier finish.
Sour Cream or Cream Cheese: Adds extra creaminess. Greek yogurt is a great substitute if you want a tangier, lighter option.
Topping: Crushed potato chips give a fun crunch, but breadcrumbs or crushed crackers work well too.
How Do I Make a Smooth and Creamy Sauce Without Lumps?
The sauce is the heart of this casserole, so getting it right is key. Be patient when making the roux and adding milk.
- Start by melting butter and stirring in flour to make a smooth paste. Cook for about a minute to avoid a raw flour taste.
- Slowly add milk in small amounts while whisking constantly to prevent lumps.
- Keep stirring gently over medium heat until the sauce thickens. Avoid boiling too hard to prevent curdling.
Once thick, reduce heat before stirring in cheese and sour cream. This keeps the sauce velvety and delicious. If lumps form, a quick whisk or blending with an immersion blender can smooth it out.
Equipment You’ll Need
- Large pot – for boiling the egg noodles quickly and evenly.
- Large skillet or saucepan – perfect for sautéing veggies and making the creamy sauce in one pan.
- Whisk – helps you mix the roux and sauce smoothly without lumps.
- 9×13 inch baking dish or oven-safe skillet – ideal for baking the casserole and crisping the topping.
- Wooden spoon or spatula – great for folding in tuna and mixing without breaking noodles.
Flavor Variations & Add-Ins
- Swap tuna for cooked shredded chicken or canned salmon for a different protein twist.
- Add sautéed mushrooms or chopped bell peppers for more veggies and texture.
- Mix in grated Parmesan or smoked gouda with cheddar for a richer, deeper cheese flavor.
- Stir in a teaspoon of curry powder or smoked paprika to give the casserole a warm, unique spice.

How Much Time Will You Need?
Prep and cooking time usually takes about 40 minutes total. This includes boiling noodles, preparing the creamy sauce, mixing everything, baking the casserole until bubbly and topped with a nice golden crust, and a few minutes resting before serving.
Step-by-Step Instructions:
1. Prepare the Oven and Noodles:
Preheat your oven to 350°F (175°C). Butter or grease a 9×13-inch baking dish or use a large oven-safe skillet. Boil the egg noodles in salted water according to package directions until they are al dente. Drain and set aside.
2. Cook the Vegetables and Make the Sauce:
In a large skillet or saucepan, melt the butter over medium heat. Add the diced onion, carrot, and mushrooms, cooking until they soften, about 4-5 minutes. Stir in the flour and cook for about 1 minute to form a roux. Slowly whisk in the milk to avoid lumps, cooking until the sauce thickens and starts to bubble gently.
3. Finish the Sauce and Combine Ingredients:
Lower the heat and stir in the shredded cheddar cheese, sour cream (or cream cheese), and Dijon mustard until smooth and creamy. Season with salt and pepper to taste. Remove from heat and gently fold in the drained tuna, cooked noodles, and frozen peas.
4. Bake the Casserole:
Transfer the mixture into your prepared baking dish or skillet. Evenly sprinkle crushed potato chips or breadcrumbs over the top to create a crispy golden crust. Bake for 20-25 minutes or until the topping is golden brown and the casserole is bubbly.
5. Serve:
Remove from the oven and let the casserole rest for a few minutes. Garnish with fresh chopped parsley before serving. Enjoy your creamy, comforting tuna noodle casserole!
Can I Use Frozen Tuna for This Recipe?
It’s best to use canned tuna packed in water for convenience and the right texture. If you want to use frozen tuna, thaw it completely in the fridge and drain any excess moisture before adding it to the casserole.
Can I Prepare the Casserole Ahead of Time?
Yes, you can mix all the ingredients and assemble the casserole a day in advance. Cover it tightly and store in the fridge. When ready to bake, add a few extra minutes to the baking time as it will be cold going into the oven.
How Should I Store Leftovers?
Keep leftovers covered in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven or microwave until warmed through, stirring occasionally.
What Can I Use Instead of Potato Chips for the Topping?
If you don’t have potato chips, crushed breadcrumbs, crackers, or even panko make excellent substitutes to add that crispy texture on top.
