Ingredients You’ll Need
This classic tuna noodle casserole recipe uses simple, accessible ingredients that you likely already have in your pantry or fridge. Here’s what you’ll need:
- 12 oz (340g) egg noodles
- 2 cans (5 oz each) tuna in water, drained and flaked
- 1 can (10.5 oz) cream of mushroom soup
- 1 cup (240ml) milk (whole or 2%)
- 1 cup (150g) frozen peas (or mixed vegetables)
- 1/2 cup (50g) shredded cheddar cheese
- 1/4 cup (25g) grated Parmesan cheese
- 1/2 cup (50g) breadcrumbs (or crushed Ritz crackers)
- 2 tablespoons butter, melted
- 1 small onion, finely chopped (optional)
- 2 cloves garlic, minced (optional)
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 1/2 teaspoon dried thyme (optional)
- 1 tablespoon fresh parsley, chopped (for garnish)
Step-by-Step Cooking Instructions
Follow these easy steps to create a creamy, golden tuna noodle casserole that’s perfect for any night of the week.
1. Preheat and Prep
Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with butter or non-stick spray. This ensures your casserole won’t stick and makes cleanup a breeze.
2. Cook the Noodles
Bring a large pot of salted water to a boil. Add the egg noodles and cook according to package instructions until al dente—usually about 6–8 minutes. Drain and set aside. Overcooking will lead to mushy noodles later, so keep an eye on the timer.
3. Sauté Aromatics (Optional but Recommended)
In a large skillet, melt 1 tablespoon of butter over medium heat. Add the chopped onion and cook for 3–4 minutes until softened. Stir in the garlic and cook for another 30 seconds until fragrant. This step adds depth of flavor, but you can skip it if you’re short on time.
4. Make the Creamy Sauce
In a large mixing bowl, combine the cream of mushroom soup, milk, salt, pepper, and thyme. Stir until smooth. Add the cooked noodles, flaked tuna, frozen peas, and sautéed onion mixture (if using). Mix gently until everything is well coated. The peas will thaw in the warm mixture, so no need to thaw them beforehand.
5. Add Cheese
Fold in the shredded cheddar cheese and half of the Parmesan. The cheese melts into the sauce, creating that signature creamy texture. Save the rest of the Parmesan for the topping.
6. Assemble the Casserole
Pour the noodle mixture into the prepared baking dish. Spread it out evenly with a spatula.
7. Make the Crispy Topping
In a small bowl, mix the breadcrumbs (or crushed crackers), melted butter, and remaining Parmesan. Sprinkle this mixture evenly over the top of the casserole. This creates a golden, crunchy crust that contrasts beautifully with the creamy interior.
8. Bake Until Golden
Bake uncovered for 25–30 minutes, or until the top is golden brown and the edges are bubbling. If the topping browns too quickly, cover loosely with foil for the last 10 minutes.
9. Rest and Serve
Let the casserole rest for 5–10 minutes before serving. This allows the sauce to set slightly, making it easier to slice and serve. Garnish with fresh parsley for a pop of color and freshness.
Chef Tips for the Best Tuna Noodle Casserole
Want to elevate your casserole from good to great? These pro tips will help you avoid common pitfalls and achieve restaurant-quality results.
- Use high-quality tuna: Opt for tuna packed in water, not oil, and choose brands with a clean, mild flavor. Albacore or chunk light tuna both work well.
- Don’t overcook the noodles: Cook them al dente, as they’ll continue to soften in the oven. Mushy noodles ruin the texture.
- Add a splash of lemon juice: A teaspoon of fresh lemon juice brightens the flavor and cuts through the richness.
- Toast the breadcrumbs: For extra crunch, toast the breadcrumbs in a dry skillet for 2–3 minutes before mixing with butter.
- Let it rest: Resist the urge to dig in immediately. Resting helps the flavors meld and prevents a runny casserole.
Common Mistakes to Avoid
Even experienced cooks can make errors with this seemingly simple dish. Here are the most common missteps—and how to avoid them.
- Using low-fat soup: Cream of mushroom soup with reduced fat or sodium can result in a thin, bland sauce. Stick to the regular version for best results.
- Skipping the topping: The crispy topping isn’t just for looks—it adds essential texture. Don’t skip it!
- Overmixing: Stir gently when combining ingredients to avoid breaking up the tuna too much.
- Baking too long: Overbaking can dry out the casserole. Stick to the recommended time and check for doneness early.
Ingredient Substitutions and Variations
One of the best things about tuna noodle casserole is its flexibility. Here are some smart swaps and creative twists to keep things interesting.
Healthier Version
- Use whole wheat or high-fiber egg noodles.
- Replace cream of mushroom soup with a homemade roux (butter, flour, milk) or Greek yogurt mixed with milk.
- Add steamed broccoli, spinach, or diced carrots for extra nutrients.
Vegan Version
- Substitute tuna with chickpeas or flaked jackfruit.
- Use vegan cream of mushroom soup and plant-based milk.

- Stir in chopped cilantro and a dollop of plain yogurt before serving.
- Serve with naan or basmati rice on the side.
