- Fresh or dried parsley – 1 tablespoon chopped or 1 teaspoon dried. Parsley adds a hint of freshness.

How to Make Tuna Casserole
Step 1: Preheat the Oven
Preheat your oven to 425°F. This ensures your casserole cooks evenly and gets that nice, golden top.
Step 2: Prepare the Crumb Topping
Combine the panko bread crumbs, melted butter, cheddar cheese, and parsley in a bowl. Mix well and set this aside for later.
Step 3: Cook the Egg Noodles
Boil the egg noodles according to the package directions until they are al dente. Once cooked, drain the noodles and rinse them under cold water to stop the cooking process.
Step 4: Sauté the Vegetables
In a skillet, melt the butter over medium heat. Add the diced onion and celery. Cook for about 5-7 minutes until they are tender and fragrant.
Step 5: Combine the Ingredients
In a large mixing bowl, combine the drained noodles, sautéed onion and celery, thawed peas, cream of mushroom soup, milk, cheddar cheese, tuna, and parsley. Stir everything until well mixed.
Step 6: Transfer to Casserole Dish
Spread the noodle mixture evenly into a 2-quart casserole dish. Make sure it's evenly distributed to ensure consistent cooking.
Step 7: Add the Topping and Bake
Sprinkle the crumb topping over the noodle mixture. Bake for 18-20 minutes or until the casserole is bubbly and the top is golden brown.

Pro Tips from My Kitchen
✓ Cook Noodles Al Dente – Cooking the noodles al dente is important because they will absorb some of the sauce as they bake, keeping them from becoming too soft.
✓ Use Quality Tuna – Choose a good quality tuna for the best flavor. Look for sustainably caught options to support responsible fishing practices.
✓ Make it Cheesy – For a cheesier casserole, use a mix of cheddar and other favorite cheeses like mozzarella or Monterey Jack to enhance the flavor and texture.
✓ Add Extra Veggies – Feel free to add more vegetables like bell peppers, mushrooms, or carrots to boost nutrition and flavor in the dish.
✓ Store Properly – If you have leftovers, store them in an airtight container in the fridge. The casserole will stay fresh for up to 3 days, making for easy lunches or quick dinners.
What Makes This Recipe Work
- The combination of cream of mushroom soup and milk creates a creamy sauce that binds the noodles and other ingredients together, ensuring every bite is full of flavor.
