STEP 1: PREHEAT THE OVEN

Begin by preheating your oven to 350°F (175°C). This ensures your casserole cooks evenly and develops a golden, bubbly top.

STEP 2: COOK THE PASTA

In a large pot, bring salted water to a boil. Add the pasta and cook according to package instructions until al dente. Drain and set aside. Cooking the pasta al dente is crucial because it will continue to cook while baking in the casserole, preventing it from becoming mushy.

STEP 3: MAKE THE CHEESE PUMPKIN SAUCE

In a large mixing bowl, combine the pumpkin puree, milk, garlic powder, onion powder, Italian seasoning, and a pinch of salt and pepper. Whisk until smooth. Then, fold in 1½ cups of the shredded cheese, reserving the remaining cheese for topping. This creamy mixture is what makes the casserole so indulgent, providing a luscious coating for the pasta.

STEP 4: COMBINE PASTA AND SAUCE

In a large baking dish, combine the cooked pasta with the cheese pumpkin sauce. Stir until the pasta is evenly coated. Ensure that every piece of pasta is enveloped in the sauce for maximum flavor in every bite.

STEP 5: ADD THE TOPPING

If using breadcrumbs, sprinkle them evenly over the casserole. Then, add the reserved shredded cheese on top for an extra cheesy finish. The breadcrumbs will create a delightful crunch that contrasts beautifully with the creamy pasta.

STEP 6: BAKE

Place the baking dish in the preheated oven and bake for 25–30 minutes, or until the casserole is bubbly and the cheese is melted and golden. The aroma that fills your kitchen during this time is sure to whet everyone’s appetite!

STEP 7: REST AND GARNISH

Remove the casserole from the oven and let it rest for about 5 minutes. This allows the sauce to set slightly, making it easier to serve. Garnish with freshly chopped parsley for a touch of color before serving.
