Ingredients
The success of this baked pasta hinges on fresh, high‑quality ingredients. The pasta provides a sturdy canvas, while the pesto—made from basil, pine nuts, garlic, Parmesan, and olive oil—infuses every strand with herbaceous richness. Sweet cherry tomatoes bring acidity and moisture, and mozzarella adds a luscious, melty finish. A few simple seasonings tie everything together and elevate the flavors.
Pasta & Vegetables
- 12 ounces (340 g) short‑tube pasta (penne or rigatoni)
- 1 ½ cups cherry tomatoes, halved
- 2 cups shredded mozzarella cheese
Pesto Sauce
- ¾ cup packed fresh basil leaves
- ¼ cup pine nuts (or walnuts)
- 2 cloves garlic, minced
- ½ cup grated Parmesan cheese
- ⅓ cup extra‑virgin olive oil
Seasonings & Garnish
- ½ teaspoon sea salt, plus more for pasta water
- ¼ teaspoon freshly ground black pepper
- ¼ teaspoon red‑pepper flakes (optional)
- Fresh basil leaves, torn (for garnish)
Together, these ingredients create a harmonious blend of creamy, tangy, and herbaceous notes. The pesto coats each pasta piece, while the cherry tomatoes release a gentle sweetness during baking. Mozzarella melts into a bubbly, golden layer that locks in moisture, ensuring every forkful is silky and satisfying. A final sprinkle of fresh basil adds a pop of color and a burst of aromatic freshness.
Step-by-Step Instructions
Preparing the Pasta
Bring a large pot of salted water to a rolling boil. Add the 12 ounces short‑tube pasta and cook until it is just shy of al dente (about 1‑2 minutes less than the package directions). This prevents the pasta from becoming mushy during the bake. Drain, reserve ¼ cup of the cooking water, and set the pasta aside.
Making the Pesto
While the pasta cooks, combine fresh basil, pine nuts, garlic, and Parmesan in a food processor. Pulse until coarsely blended, then drizzle in the olive oil while the processor runs, creating a smooth, glossy sauce. Season with salt and pepper. If the pesto feels too thick, stir in a tablespoon of the reserved pasta water to loosen it.
Combining & Baking
- Mix Pasta and Pesto. In a large bowl, toss the drained pasta with the freshly made pesto, ensuring every piece is evenly coated. The oil in the pesto prevents the pasta from sticking together during baking.
- Layer with Tomatoes. Transfer the pesto‑coated pasta to a greased 9‑x 13‑inch baking dish. Evenly scatter the halved cherry tomatoes over the top. The tomatoes will soften and release juices, creating pockets of bright acidity.
- Add Mozzarella. Sprinkle the shredded mozzarella uniformly across the surface. The cheese will melt, turn golden, and form a slightly crispy crust that adds texture.
- Season & Bake. Sprinkle a pinch of red‑pepper flakes (if using) and a light drizzle of olive oil. Cover the dish with foil and bake in a preheated 375°F (190°C) oven for 15 minutes. Remove the foil and continue baking for another 10 minutes, or until the cheese is bubbling and lightly browned.
- Rest & Garnish. Allow the casserole to rest for 5 minutes after removing it from the oven. This rest period lets the sauce thicken slightly and the cheese set, making it easier to serve. Finish with a handful of torn fresh basil for color and fragrance.
Tips & Tricks
Perfecting the Recipe
Undercook the Pasta Slightly. This prevents a mushy texture after the bake and ensures the pasta finishes cooking in the oven, absorbing more pesto flavor.
Use Fresh Basil. Fresh leaves give a brighter, more aromatic pesto than dried, and they retain their color better during blending.
Toast Pine Nuts. Lightly toasting the nuts before processing adds a nutty depth that elevates the overall sauce.
Flavor Enhancements
A splash of fresh lemon juice added after baking brightens the finished dish. For a smoky twist, stir in a teaspoon of smoked paprika into the pesto. Finish with a drizzle of high‑quality extra‑virgin olive oil right before serving for an extra layer of richness.
Common Mistakes to Avoid
Don’t over‑bake; the mozzarella can become rubbery if left too long. Also, avoid using too much water when cooking pasta—excess moisture will dilute the pesto and result in a soggy casserole.
Pro Tips
Reserve Pasta Water. Adding a spoonful to the pesto helps emulsify the sauce and ensures a silky coating.
Use a Lightly Greased Dish. This prevents sticking and makes cleanup a breeze while allowing the cheese to brown evenly.
Season in Layers. Lightly salt the tomatoes and pasta before assembling; each layer builds depth.
Finish with Fresh Herbs. Adding basil after baking preserves its bright flavor and prevents wilting.
Variations
Ingredient Swaps
Swap the short‑tube pasta for fusilli, farfalle, or even gluten‑free penne if you prefer. Replace pine nuts with toasted almonds or walnuts for a different nutty profile. For a richer sauce, blend in a tablespoon of ricotta cheese. If you love a bit of heat, add sliced jalapeños alongside the tomatoes.
Dietary Adjustments
For a dairy‑free version, substitute mozzarella with a plant‑based cheese that melts well and use nutritional yeast instead of Parmesan. To keep it low‑carb, replace the pasta with spiralized zucchini or shirataki noodles. Gluten‑free eaters can use certified gluten‑free pasta and ensure the pesto contains no wheat‑based additives.
Serving Suggestions
Pair the baked pasta with a simple arugula salad tossed in lemon vinaigrette for contrast. Crusty Italian bread or garlic‑buttered focaccia is perfect for sopping up any extra sauce. For a heartier plate, serve alongside roasted chicken thighs or grilled sausage links.
Storage Info
Leftover Storage
Allow the casserole to cool to room temperature, then transfer it to an airtight container. It keeps well in the refrigerator for 3‑4 days. For longer storage, portion into freezer‑safe bags or containers, flattening the layers for even freezing, and store up to 3 months. Label with the date for easy reference.
Reheating Instructions
Reheat leftovers in a preheated 350°F (175°C) oven, covered with foil, for 15‑20 minutes until hot throughout. Removing the foil for the last 5 minutes restores the cheese’s golden crust. In a pinch, microwave individual portions on medium power for 2‑3 minutes, stirring halfway and adding a splash of broth or water to prevent drying.
