🔪 Step-by-Step Instructions for the Perfect Bake

 

Follow these steps to create your delicious tuna pasta bake:

1. Prep and Pasta

 

• Preheat your oven to 400°F (200°C). Lightly grease a 9×13 inch (3-quart) baking dish.

• Bring a large pot of salted water to a boil. Cook the pasta until it is firmly al dente (about 1 minute less than package directions). Drain the pasta and return it to the pot.

2. Mix the Creamy Filling

 

• In the pot with the pasta, pour in the entire jar of Alfredo sauce. Add the thoroughly drained tuna, frozen peas, garlic powder, salt, and pepper.

• Stir gently until all the ingredients are well-combined and the pasta is coated in the creamy sauce.

• Tip: If the sauce seems too thick, add a splash of milk to loosen it slightly.

3. Top and Bake

 

• Pour the creamy pasta mixture into the prepared baking dish, spreading it into an even layer.

• Sprinkle the 1 cup of Mozzarella cheese evenly over the top.

• For the crispy topping, mix the 1/2 cup Parmesan cheese with the Panko breadcrumbs and sprinkle this mixture over the Mozzarella.

• Bake for 15–20 minutes, or until the sauce is bubbly around the edges and the cheese topping is melted and golden brown.

• Let the casserole cool for 5-10 minutes before serving to allow the sauce to set.

💡 Expert Tips for the Best Creamy Texture

 

Achieving that perfect, non-watery casserole requires attention to detail. Follow these tips for a consistently excellent creamy tuna casserole:

1. Squeeze the Tuna: After draining the tuna, press down firmly on the flakes in the colander using a spoon or paper towel. Excess water is the number one cause of a watery sauce.

2. No Overcooking the Pasta: Undercooking the pasta to al dente is critical. It absorbs liquid in the oven, which both thickens the sauce and ensures the pasta remains firm, not mushy.

3. Add a Flavour Boost: Consider stirring in 1 tablespoon of sun-dried tomato or basil pesto into the Alfredo sauce mixture. This adds a layer of acidity and herbaceousness that beautifully cuts through the richness of the cream.

4. Cover for Even Heat: If the top browns too quickly, cover the casserole dish loosely with aluminum foil for the last 5 minutes of baking.

This easy tuna Alfredo casserole is a delicious testament to how simple swaps can completely revitalize a classic. It’s the perfect centerpiece for a satisfying family dinner.
