How to Make Tuna Casserole
-
Preheat your oven to 180°C (350°F). This is essential for achieving that perfect bubbling, golden crust on your casserole.
-
Boil salted water in a large pot and cook the egg noodles until al dente, which should take about 6 minutes. You want them firm, as they’ll soften more in the oven. Drain the noodles well.
-
Melt the unsalted butter in a saucepan over medium heat, then sauté the yellow onion until it becomes translucent, around 3-4 minutes. Don’t forget to add the minced garlic and sauté for an additional 30 seconds for that aromatic flair!
-
Lower the heat and add the cream of mushroom soup and whole milk. Whisk until smooth, then season generously with sea salt and ground black pepper to taste.
-
Stir in the drained tuna and frozen peas, warming through for about 2 minutes. This ensures that everything is heated evenly and ready to combine.
-
Combine the cooked noodles with the tuna mixture and shredded cheddar cheese in a large bowl. Gently stir until everything is well-coated and mixed together.
-
Grease a 20x20cm baking dish with butter or oil, then spread the noodle mixture evenly across the bottom.
-
Mix the crushed butter crackers or breadcrumbs with melted butter in a separate bowl. Sprinkle this crunchy mixture evenly over the casserole for that delightful topping!
-
Bake uncovered in the preheated oven for 25-30 minutes, or until the casserole is bubbling and the top is a lovely golden brown.
-
Cool for 5-10 minutes before serving. If you like, garnish with fresh parsley for a pop of color and freshness.
Optional: Add a sprinkle of paprika on top for a touch of color and flavor!

Tuna Casserole Recipe FAQs
How do I choose the best egg noodles for my tuna casserole?
Absolutely! Look for egg noodles labeled “wide” or “medium” for a perfect balance of texture. Choose ones that are slightly firm and free from dark spots. If you have gluten sensitivities, gluten-free pasta can also work wonderfully in this dish.
What is the best way to store leftover tuna casserole?
Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Make sure the casserole has cooled to room temperature before sealing the container. This helps maintain its creamy texture and flavor, so it’s just as delightful when you reheat it!
Can I freeze tuna casserole?
Very much! To freeze, let the casserole cool completely, then wrap it tightly with plastic wrap, followed by aluminum foil, or place it in an airtight container. It can be frozen for up to 3 months. When ready to enjoy, thaw it overnight in the fridge and reheat in the oven for the best results!
What should I do if my tuna casserole seems too dry when baking?
If you find your casserole lacks moisture, don’t worry! Next time, you can incorporate a splash of milk or cream into the sauce before mixing it with the noodles. Alternatively, reserve some of the cream of mushroom soup to drizzle over the top during baking, keeping it rich and flavorful.
Are there any dietary considerations for tuna casserole?
Definitely! If you’re serving this dish to guests with allergies, be aware of common allergens like dairy and gluten. You can use lactose-free milk and cheese alternatives which work beautifully. For those needing gluten-free options, simply substitute the egg noodles with gluten-free varieties, and ensure your cream soup is gluten-free as well.
How can I enhance the flavors in my tuna casserole?
To elevate the taste, consider adding sautéed mushrooms, chopped bell peppers, or even some fresh herbs like dill or parsley.
