Gathering Ingredients

Ingredient checklist for the bake

• 300g penne or rigatoni 🍝
• 2 cups cooked shredded chicken 🍗
• 1 cup basil pesto (store-bought or homemade) 🌿
• 1 cup heavy cream 🥛
• 1 cup shredded mozzarella 🧀
• 1/2 cup grated Parmesan 🧀
• 1 small onion, diced 🧅
• 2 cloves garlic, minced 🧄
• 2 tbsp olive oil 🫒
• 1/4 cup reserved pasta water or chicken broth 🥣
• Salt and black pepper to taste 🧂
• 1 cup cherry tomatoes, halved (optional) 🍅
• 1/2 cup breadcrumbs for topping (optional) 🍞
• Fresh basil leaves for garnish 🌱

Preparation Overview

Smart prep for smooth assembly

• If your sauce feels too thick when mixing, add a little of the reserved liquid a splash at a time until it loosens.
• If the protein seems dry, warm it briefly in the pan with a touch of the sauce to rehydrate before folding into the pasta.
• If you're short on time, assemble components cold and bake a bit longer—just watch for browning on top.

Cooking / Assembly Process

Step-by-step assembly and baking instructions

1. Preheat oven to 180°C (350°F). Grease a 20x30 cm (8x12 in) baking dish lightly with oil.
2. Bring a large pot of salted water to a boil and cook the pasta 2 minutes less than package directions (it will finish cooking in the oven). Drain, reserving 1/4 cup of pasta water.
3. While pasta cooks, heat 2 tbsp olive oil in a skillet over medium heat. Sauté the diced onion until translucent, about 4–5 minutes.
4. Add minced garlic to the skillet and cook 30–60 seconds until fragrant. Add the shredded chicken and stir to warm through.
5. Reduce heat to low and stir in the basil pesto and heavy cream. Add the reserved pasta water a little at a time to loosen the sauce until creamy and smooth. Season with salt and pepper.
6. Fold the drained pasta into the sauce until evenly coated. If using cherry tomatoes, fold them in now.
7. Transfer the pasta mixture to the prepared baking dish. Sprinkle shredded mozzarella and grated Parmesan evenly on top. If using, sprinkle breadcrumbs for a crunchy topping.
8. Bake in the preheated oven for 15–20 minutes, until cheese is melted and golden and the casserole is bubbling.
9. Remove from oven and let rest 5 minutes. Garnish with fresh basil leaves, slice, and serve warm.

Serving Suggestions

Simple service ideas to elevate the moment

• Scoop from the center for the cheesiest portion or from the edges for slightly crispier bites.
• Allow resting time so the sauce sets slightly—this makes neat slices easier and improves texture.

Storage & Make-Ahead Tips

Prep ahead and keep leftovers delicious

• Cool the dish to near room temperature before covering and refrigerating to preserve texture and food safety.
• Store in an airtight container for best results, and reheat gently to avoid drying out—briefly covered in the oven or reheated portion-by-portion in a skillet with a splash of liquid to restore creaminess.
• For freezing, wrap tightly and label; thaw overnight in the fridge before bringing back to the oven to finish so textures recover more predictably.
