  • Pasta: 400 g (14 oz) elbow macaroni or short pasta
  • Chicken & Marinade: 2 large boneless, skinless chicken breasts (about 400 g/14 oz), 3 tbsp basil pesto, 1 tbsp olive oil, 1/2 tsp salt, 1/4 tsp black pepper
  • Cheese Sauce: 3 tbsp unsalted butter, 3 tbsp all-purpose flour, 2 cups (480 ml) whole milk (warmed), 1 cup (240 ml) heavy cream, 2 cups (200 g) shredded sharp cheddar cheese, 1 cup (90 g) grated mozzarella cheese, 1/2 cup (50 g) grated parmesan cheese, 1/2 tsp garlic powder, 1/4 tsp ground nutmeg, salt and pepper to taste
  • Topping: 1 cup (100 g) panko breadcrumbs, 2 tbsp melted butter, 1/4 cup (25 g) grated parmesan cheese, 2 tbsp basil pesto

Instructions

Step 1
Preheat oven to 200°C (400°F). Grease a 23x33 cm (9x13-inch) baking dish.
Step 2
Cook the pasta in salted boiling water 2 minutes less than package instructions (it will finish in the oven). Drain and set aside.
Step 3
While pasta cooks, butterfly the chicken breasts and cut into bite-sized pieces. Toss with 3 tbsp pesto, olive oil, salt, and pepper. Let marinate 10 minutes.
Step 4
In a large skillet over medium-high heat, sear the chicken pieces until just cooked through, about 5–6 minutes. Remove from heat.
Step 5
For the cheese sauce, melt butter in a large saucepan over medium heat. Whisk in flour and cook 1 minute. Gradually whisk in milk and cream. Stir constantly until slightly thickened, about 3–4 minutes.
Step 6
Lower heat and stir in cheddar, mozzarella, and parmesan cheeses until melted and smooth. Add garlic powder, nutmeg, salt, and pepper. Remove from heat.
Step 7
Combine the cooked pasta, cheese sauce, and pesto chicken in a large bowl. Mix gently to combine.
Step 8
Pour mixture into prepared baking dish.
Step 9
In a small bowl, mix panko, melted butter, parmesan, and pesto for the topping. Sprinkle evenly over the casserole.
Step 10
Bake 20–25 minutes, until topping is golden and casserole is bubbling. Let rest 5–10 minutes before serving.

Zusatztipps für die Zubereitung

To ensure the best results, always cook your pasta al dente. Since it continues to cook in the oven while absorbing the cheese sauce, undercooking it initially prevents it from becoming mushy. Additionally, make sure to warm your milk before adding it to the flour and butter mixture to ensure a silky-smooth roux without any lumps.

Varianten und Anpassungen

For a faster weeknight version, you can substitute the fresh chicken with a pre-cooked rotisserie chicken—simply toss the shredded meat with pesto before folding it into the pasta. If you want to experiment with the cheese blend, try using smoked gouda or fontina to add a different layer of richness to the sauce.

Serviervorschläge

This hearty Baked Pesto Chicken Mac & Cheese is quite rich, so it pairs beautifully with a crisp green salad tossed in a light vinaigrette. For the perfect beverage, serve it alongside a chilled glass of Sauvignon Blanc, which cuts through the creaminess and highlights the herbal notes of the pesto.

Common Questions

Can I make this ahead of time?

Yes, assemble the entire casserole up to 24 hours in advance, cover tightly, and refrigerate. Add 10-15 minutes to baking time if baking cold from the refrigerator.

What other cheeses work well?

Smoked gouda adds depth, fontina brings excellent melt, gruyere offers nutty notes, or provolone provides mild creaminess. Keep some sharp cheddar for that classic tangy bite.

Can I use rotisserie chicken?

Absolutely. Shred a rotisserie chicken and toss with 3 tbsp pesto before folding into the cheese sauce. Skip the searing step and combine everything before baking.

How do I store leftovers?

Cover tightly and refrigerate for up to 4 days. Reheat individual portions in the microwave or the entire casserole in a 350°F oven covered with foil until heated through, about 20 minutes.

Can I freeze this casserole?

Yes, assemble and wrap tightly before baking. Freeze for up to 3 months. Thaw overnight in the refrigerator, then bake as directed, adding 10-15 minutes if needed.

What pasta shapes work best?

Elbow macaroni, cavatappi, penne, or shells all work beautifully. Short pasta with nooks and crannies helps hold the creamy cheese sauce and crispy topping.

How To Make It

Step 01

Prepare the oven and baking dish: Preheat oven to 400°F. Grease a 9x13-inch baking dish thoroughly with butter or cooking spray.

Step 02

Cook the pasta: Bring a large pot of salted water to boil. Cook pasta 2 minutes less than package instructions to maintain firmness, as it will continue cooking in the oven. Drain and set aside.

Step 03

Prepare and marinate chicken: While pasta cooks, butterfly the chicken breasts horizontally and cut into bite-sized pieces. Toss with 3 tablespoons basil pesto, olive oil, salt, and pepper. Allow to marinate for 10 minutes.

Step 04

Sear the chicken: Heat a large skillet over medium-high heat. Sear the pesto-marinated chicken pieces until cooked through, approximately 5-6 minutes. Remove from heat and set aside.

Step 05

Create the cheese sauce base: In a large saucepan over medium heat, melt butter. Whisk in flour and cook for 1 minute, stirring constantly to create a roux.

Step 06

Complete the cheese sauce: Gradually whisk in warmed milk and heavy cream. Continue stirring constantly until the sauce thickens slightly, approximately 3-4 minutes. Lower heat and stir in cheddar, mozzarella, and parmesan cheeses until completely melted and smooth. Season with garlic powder, nutmeg, salt, and pepper. Remove from heat.

Step 07

Combine all components: In a large mixing bowl, gently combine the cooked pasta, cheese sauce, and pesto chicken until evenly distributed. Be careful not to break the pasta.

Step 08

Transfer to baking dish: Pour the pasta mixture into the prepared 9x13-inch baking dish, spreading evenly.

Step 09

Prepare and apply topping: In a small bowl, combine panko breadcrumbs, melted butter, parmesan cheese, and 2 tablespoons basil pesto. Mix until breadcrumbs are evenly coated. Sprinkle the topping evenly across the casserole surface.

Step 10

Bake and rest: Bake for 20-25 minutes until the topping is golden brown and the casserole bubbles around the edges. Remove from oven and allow to rest for 5-10 minutes before serving.
