Baking the Spaghetti Casserole

Baking is the final step that transforms your carefully layered ingredients into a golden, bubbly delight. Follow these steps to bake your spaghetti casserole to perfection.

Preheat the Oven

1. Set the Temperature
   • Preheat your oven to 375°F (190°C).
   • Ensure the rack is positioned in the center of the oven for even cooking.

Cover the Casserole

1. Use Aluminum Foil
   • Cover the baking dish tightly with aluminum foil to trap steam.
   • This helps melt the cheese and keeps the casserole moist during the initial baking phase.
2. Prevent Sticking
   • Lightly grease the underside of the foil with cooking spray to prevent cheese from sticking.

Bake the Casserole

1. First Bake
   • Place the covered dish in the preheated oven.
   • Bake for 25–30 minutes to allow the ingredients to meld together and the cheese to melt.
2. Uncover for Browning
   • Remove the foil and bake uncovered for an additional 10–15 minutes.
   • This step allows the cheese to bubble and develop a golden crust.

Check for Doneness

1. Bubbling and Browning
   • The casserole is ready when the edges are bubbling and the top is golden brown.
2. Internal Temperature
   • Use a food thermometer to ensure the center of the casserole reaches 165°F (74°C), especially if using poultry.

Cool Before Serving

1. Resting Time
   • Allow the casserole to rest for 5–10 minutes after removing it from the oven.
   • This helps the layers set and makes slicing easier.
2. Garnish
   • Add a final sprinkle of fresh parsley or basil for an elegant finish.

Preheat your oven to 375°F. Cover the casserole with foil and bake for 30 minutes. Uncover and bake for an additional 10 minutes to achieve a golden, bubbly crust.
