Flavor & Texture Highlights
The pesto brings a bright combination of fresh basil, garlic, Parmesan, olive oil, and nutty flavor. The pasta soaks up the sauce while baking, becoming tender and wonderfully flavorful.
On top, melted mozzarella creates a creamy, stretchy layer with golden-brown spots from the oven. Toasted pine nuts add a delicate crunch, while fresh basil gives everything a fresh finish.
How to Make Cheesy Pesto Pasta Bake
Begin by cooking the pasta until just al dente. Since the pasta will continue cooking in the oven, avoid overcooking it at this stage.
Prepare a creamy pesto sauce by combining basil pesto with heavy cream, Parmesan, and seasonings. Toss the cooked pasta with the sauce until every piece is evenly coated.
Transfer the pasta to a baking dish and cover generously with shredded mozzarella. Bake until the cheese is melted, bubbling, and beautifully golden around the edges.
Finish with fresh basil and toasted pine nuts before serving. Let the pasta rest for a few minutes so the sauce can settle slightly while the cheese stays deliciously gooey.
Helpful Tips
- Cook the pasta just until al dente so it does not become too soft during baking.
- Use good-quality basil pesto for the best flavor.
- Freshly shredded mozzarella melts more smoothly than pre-shredded cheese.
- For extra flavor, add a little freshly grated Parmesan over the mozzarella before baking.
- Toast the pine nuts gently in a dry skillet until lightly golden, watching them closely because they can burn quickly.
- For a heartier meal, add cooked chicken, Italian sausage, or sautéed mushrooms.
- Let the baked pasta rest for about 5 minutes before serving.

Ingredients
- 12 ounces penne or rigatoni pasta
- 1 cup basil pesto
- 3/4 cup heavy cream
- 1/2 cup freshly grated Parmesan cheese

Instructions
- Preheat the oven: Heat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with olive oil.

- Add the cheese: Sprinkle the shredded mozzarella evenly over the top, followed by a little extra Parmesan if desired.
- Bake: Place the dish in the oven and bake for 20–25 minutes, or until the cheese is completely melted, bubbling, and golden brown in spots.
- Toast the pine nuts: While the pasta bakes, place the pine nuts in a dry skillet over medium-low heat. Toast for 2–4 minutes, stirring often, until lightly golden.
