Preparation Phase & Tools to Use

Before diving in, it’s best to gather the right tools to make the cooking process smooth and efficient. You’ll need:

• Large Pot: To cook the egg noodles until al dente.
• Mixing Bowl: For combining the noodles, tuna, peas, and sauce mixture evenly.
• 9×13 Baking Dish: Essential for layering and baking the casserole evenly.
• Cheese Grater: If you’re grating fresh cheese, which melts better and tastes richer than pre-shredded.
• Wooden Spoon or Silicone Spatula: Helps with mixing ingredients gently without breaking the noodles.
• Measuring Cups and Spoons: Accuracy is key when making sauces and seasoning.

Each tool plays a role in maintaining the texture and balance of flavors. A good baking dish ensures even cooking while proper mixing prevents clumps and uneven layering.

Preparation Tips

Cook the noodles just until al dente, as they’ll continue softening while baking in the sauce. Drain them well to prevent a watery casserole. Use chunk light tuna in water for a milder, flakier texture that blends seamlessly into the dish. Fresh or frozen peas work well—just thaw frozen peas ahead of time. If your sauce feels too thick, a splash of milk will loosen it up before baking. And don’t skip the topping—a mix of breadcrumbs and cheese gives this casserole that golden, irresistible crunch.

Ingredients for this Tuna Casserole

• 12 oz egg noodles
• 2 cans (5 oz each) tuna in water, drained and flaked
• 1 cup frozen peas, thawed
• 1 can (10.5 oz) cream of mushroom soup
• 1/2 cup sour cream
• 1/2 cup milk
• 1 tsp garlic powder
• 1/2 tsp onion powder
• Salt and black pepper to taste

• 1/2 cup panko breadcrumbs
• 2 tbsp butter, melted
• Optional: 1 tbsp chopped parsley for garnish

Step 1: Cook the Noodles

Bring a large pot of salted water to a boil. Add the egg noodles and cook until just al dente according to package directions—usually about 6-7 minutes. Drain well and set aside.

---

Step 2: Prepare the Sauce

In a large mixing bowl, whisk together the cream of mushroom soup, sour cream, milk, garlic powder, onion powder, salt, and black pepper. The mixture should be smooth and pourable. Adjust the seasoning to your taste.

---

Step 3: Combine the Ingredients

Add the drained tuna, thawed peas, and cooked noodles to the sauce mixture. Stir gently to combine everything evenly without breaking the noodles. Fold in 1 cup of shredded cheese into the mix for extra creaminess.

---

Step 4: Transfer to Baking Dish

Lightly grease a 9×13-inch baking dish with non-stick spray or butter. Pour the casserole mixture into the dish and spread it out evenly. Sprinkle the remaining cheese over the top.

---

Step 5: Add Crunchy Topping

In a small bowl, mix the panko breadcrumbs with the melted butter until the crumbs are evenly coated. Sprinkle this mixture over the casserole to create a crisp, golden topping during baking.

---

Step 6: Bake to Perfection

Preheat your oven to 375°F (190°C). Bake the casserole uncovered for 25–30 minutes or until bubbly around the edges and the top is golden brown.

---

Step 7: Serve and Enjoy

Remove from the oven and let it rest for 5 minutes. Garnish with chopped parsley if desired, then serve warm. This dish pairs beautifully with a light salad or roasted vegetables.

Notes

This Tuna Casserole is incredibly forgiving and customizable. You can swap the cream of mushroom soup with cream of celery or even a homemade béchamel sauce if you prefer. Feel free to toss in extra vegetables like sautéed mushrooms, chopped spinach, or diced bell peppers for added nutrition and texture. For a gluten-free option, use gluten-free noodles and certified gluten-free cream soup. And if you want a richer flavor, a dash of Worcestershire sauce or a spoonful of Dijon mustard mixed into the sauce can elevate the dish beautifully.

Watch Out for These Mistakes While Cooking

• Overcooking the noodles: Remember that noodles will continue to cook in the oven, so boil them just until al dente.
• Skipping the seasoning: The soup adds salt, but it’s important to taste and adjust with pepper and any additional seasonings before baking.
• Too much liquid: Don’t go overboard with milk or soup, or your casserole may turn out soupy.
• Uneven mixing: Mix gently but thoroughly to ensure every bite has tuna, peas, and sauce.
• Neglecting the topping: The buttery breadcrumb topping adds texture. Don’t skip it unless you need a low-carb option.
