Ingredients
The backbone of this bake is a balance of protein, pasta, and a luxuriously creamy pesto sauce. Fresh chicken breasts provide lean protein that absorbs the herb‑laden sauce, while short‑cut penne offers a perfect bite‑size vessel. The sauce itself leans on quality olive oil, fragrant basil, toasted pine nuts, and a trio of cheeses that create a silky coating. A handful of vegetables adds texture and color, and a few pantry staples tie everything together.
Main Ingredients
- 4 boneless, skinless chicken breasts (about 1½ lbs)
- 12 oz (340 g) penne pasta
- 2 cups fresh broccoli florets
Pesto & Cream Sauce
- 1½ cups packed fresh basil leaves <
- ¼ cup pine nuts, lightly toasted
- 2 cloves garlic, minced
- ½ cup extra‑virgin olive oil
- 1 cup heavy cream
- ½ cup grated Parmesan cheese
- ½ cup shredded mozzarella cheese
Seasonings & Garnish
- Salt and freshly ground black pepper, to taste
- ¼ teaspoon red‑pepper flakes (optional)
- 2 tablespoons grated Pecorino Romano, for garnish
Each component plays a purpose: the chicken brings lean protein, the pasta provides a comforting base, and the broccoli adds a pop of green and a bite of freshness. The pesto’s basil and pine nuts infuse the sauce with herbaceous depth, while the cream and cheeses create a luscious mouthfeel. Seasonings amplify the flavors, and the final sprinkle of Pecorino adds a salty, sharp finish that ties the whole bake together.
Step-by-Step Instructions
Preparing the Chicken & Pasta
Begin by patting the chicken breasts dry, then slice each breast into bite‑size strips. Season generously with salt, pepper, and a pinch of red‑pepper flakes. While the chicken rests, bring a large pot of salted water to a boil, add the penne, and cook until al dente—about 9 minutes. Reserve ½ cup of pasta water before draining; this starchy liquid will help bind the sauce later.
Making the Pesto Cream Sauce
- Toast the pine nuts. Heat a dry skillet over medium heat, add the pine nuts, and stir constantly for 2‑3 minutes until golden and fragrant. Transfer to a bowl to cool; this step deepens the nutty flavor of the pesto.
- Blend the pesto. In a food processor combine the basil, toasted pine nuts, minced garlic, and a generous pinch of salt. Pulse while slowly drizzling in the olive oil until a smooth, glossy paste forms. Scrape the sides to ensure even emulsification.
- Create the cream base. In a saucepan over medium heat, whisk the heavy cream until it just begins to simmer. Reduce the heat to low and stir in the pesto, Parmesan, and mozzarella. Continue whisking until the cheeses melt and the sauce thickens, about 3‑4 minutes. If the sauce seems too thick, add a splash of the reserved pasta water.
Assembling & Baking
Preheat the oven to 375°F (190°C). In a large skillet, heat a tablespoon of olive oil over medium‑high heat. Quickly sear the chicken strips for 2‑3 minutes per side—just enough to develop color without cooking through. Add the broccoli florets and sauté for another 2 minutes, allowing them to retain a slight crunch.
- Combine everything. Toss the cooked penne, seared chicken, and broccoli together in the skillet. Pour the pesto‑cream sauce over the mixture, stirring gently to coat every piece evenly. Transfer the combined contents to a greased 9‑x‑13‑inch baking dish, spreading into an even layer.
- Top and bake. Sprinkle an additional ¼ cup mozzarella and a handful of grated Pecorino on top. Place the dish in the preheated oven and bake for 18‑20 minutes, or until the cheese is bubbly and lightly golden. For an extra crust, switch to broil for the final 2 minutes, watching closely to avoid burning.
- Rest before serving. Remove the bake from the oven and let it rest for 5 minutes. This short rest allows the sauce to set, making it easier to slice and serve while keeping the chicken juicy.
Finishing & Serving
Before plating, garnish with a drizzle of extra‑virgin olive oil, a sprinkle of fresh basil leaves, and the remaining Pecorino. Serve hot, paired with a simple green salad or crusty bread to mop up any lingering sauce. The dish stays warm for about 30 minutes, making it ideal for family-style dining.
Tips & Tricks
Perfecting the Recipe
Dry the chicken thoroughly. Moisture on the surface creates steam, preventing a good sear. Pat the strips with paper towels for that coveted caramelized crust.
Don’t over‑cook the pasta. Al dente pasta continues to cook in the oven, absorbing sauce without becoming mushy.
Use fresh basil. Fresh leaves give a brighter, more aromatic pesto than dried basil, which can taste muted after baking.
Reserve pasta water. The starchy liquid helps the sauce cling to the pasta and prevents it from drying out during baking.
Flavor Enhancements
Add a squeeze of fresh lemon juice just before serving to brighten the pesto’s earthiness. A pinch of smoked paprika in the sauce adds subtle depth, while a spoonful of ricotta folded in at the end creates extra creaminess.
Common Mistakes to Avoid
Skipping the brief rest after baking causes the sauce to run off the plate, making the dish look sloppy. Also, avoid high oven temperatures; a moderate 375°F ensures the cheese melts evenly without scorching the pesto.
Pro Tips
Blend the pesto by hand. A mortar and pestle preserve the bright green color and give a slightly coarser texture that holds up better in the oven.
Use a mix of cheeses. Combining Parmesan, mozzarella, and a dash of Gruyère adds complexity and a beautifully stretchy top.
Finish with a drizzle of nut‑oil. A light splash of toasted walnut oil just before serving adds a nutty aroma that elevates the pesto.
Cool the baking dish on a rack. This prevents the bottom from becoming soggy and keeps the crust crisp.
Variations
Ingredient Swaps
Replace chicken with sliced Italian sausage, shrimp, or firm tofu for a different protein profile. Swap penne for fusilli or rigatoni to catch more sauce. If basil isn’t on hand, try spinach‑arugula pesto or sun‑dried tomato pesto for a richer, tangier twist.
Dietary Adjustments
For gluten‑free diners, use brown rice pasta or chickpea pasta, ensuring it’s cooked al dente. To make the dish dairy‑free, substitute heavy cream with coconut cream and use nutritional yeast in place of Parmesan. A low‑carb version can omit the pasta entirely and serve the chicken and vegetables over cauliflower rice.
Serving Suggestions
Pair the bake with a crisp Caesar salad, roasted garlic bread, or a simple quinoa pilaf. A glass of chilled Sauvignon Blanc or light Chianti balances the richness, while a lemon‑y sorbet makes a refreshing finish.
Storage Info
Leftover Storage
Allow the bake to cool to room temperature, then portion into airtight containers. Refrigerate for up to 4 days; the flavors actually meld, making leftovers taste even better. For longer keeping, freeze sealed portions for up to 3 months—wrap tightly with plastic wrap before placing in a freezer‑grade bag.
Reheating Instructions
Reheat refrigerated leftovers in a 350°F oven, covered with foil, for 15‑20 minutes until steaming hot. Uncover for the final 5 minutes to restore the cheese crust. In the microwave, add a splash of milk or broth, cover, and heat on medium for 2‑3 minutes, stirring halfway through.
