Ingredients Needed to Make Creamy Pesto Chicken Pasta Bake

You’ll need:

• 10 oz rigatoni (about ¾ of a 1 lb box)
• 1.5 lbs chicken tenderloins, diced
• 1.5 tablespoons Italian seasoning
• ⅓ cup prepared pesto
• 1.5 cups shredded mozzarella cheese
• 1 cup Parmesan cheese (grated or shredded)
• 2 tablespoons butter
• 1 medium yellow onion, diced
• 4 garlic cloves, minced
• 2 teaspoons Cajun seasoning (or use the homemade mix below)
• 1 teaspoon red pepper flakes (optional for spice lovers)
• 3 cups whole milk (or half-and-half for richer sauce)
• 8 oz sun-dried tomatoes, oil drained
• 1.5 cups broccoli florets
• 2 cups baby spinach
• Olive oil, salt, and freshly ground black pepper to taste

Homemade Cajun Seasoning Mix:
1 tbsp paprika, 1 tsp salt, 2 tsp garlic powder, 1 tsp onion powder, 1 tsp chili powder, 1 tsp dried parsley, ¾ tsp thyme, ½ tsp oregano, ½ tsp brown sugar, ¾ tsp cayenne (adjust for spice), and ¼ tsp cracked pepper. Mix it all and store extra in a spice jar—it’s fantastic on shrimp, veggies, or even grilled steak.

Instructions to Make Creamy Pesto Chicken Pasta Bake – Step by Step

Step 1: Season and Cook the Chicken

Start by drizzling your diced chicken with olive oil in a large bowl. Toss it with Italian seasoning, a teaspoon of salt, and a good grind of pepper. Make sure every piece is coated—this builds that beautiful base flavor. While you prep, set a pot of water to boil for your rigatoni.

Heat an oven-safe skillet (cast iron is perfect) over medium heat, add olive oil to coat the bottom, and sear the chicken for 4–5 minutes per side until golden brown. Reduce heat and cook another 3–4 minutes until the chicken is just cooked through. Transfer it to a plate. Don’t wash that pan—you’ll use it for the sauce, and those browned bits are pure flavor gold.

Step 2: Sauté the Aromatics

Lower the heat to medium-low and melt 2 tablespoons of butter in the same pan. Add diced onions and sauté until they turn soft and translucent—about 3 minutes. Add minced garlic and stir for another 30 seconds, just until it smells heavenly. This is where your kitchen starts to smell like an Italian restaurant, and you’ll want to cancel your dinner reservations because, trust me, this is better.

Step 3: Build the Creamy Cajun-Pesto Sauce

Pour in the milk slowly, whisking to avoid lumps. Sprinkle in Cajun seasoning and red pepper flakes (if you’re into a little heat). Add a pinch of salt and pepper, stir, then toss in the sun-dried tomatoes and broccoli. Let everything simmer gently for about 5 minutes until the broccoli softens slightly. The sauce will thicken as it cooks. Meanwhile, your pasta should be boiling—cook it to al dente so it holds up during baking.

Step 4: Combine Pasta, Chicken, and Pesto

Once the sauce is ready, add in your baby spinach, stirring until it wilts. Drain your rigatoni, then fold it right into the creamy sauce. Add back the cooked chicken, then stir in the prepared pesto. This is the magic moment—the pesto swirls into the sauce, turning it a gorgeous greenish-gold color while releasing that garlicky, herby aroma. Give it a taste test and adjust seasoning if needed.

Step 5: Add the Cheesy Layer and Broil

Now for the best part: the cheese blanket. Sprinkle the mozzarella and Parmesan evenly over the top. Pop the skillet under your oven’s broiler for 3–5 minutes until the top is bubbly, golden, and slightly crisp on the edges. Keep an eye on it—it can go from perfect to “call the smoke alarm” fast. When it’s ready, pull it out and let it rest for 5 minutes. That waiting time helps the sauce thicken and makes it easier to serve.

Step 6: Serve and Savor

Spoon generous portions into bowls, and get ready for compliments. The creamy sauce clings to the rigatoni, the chicken is juicy, and the sun-dried tomatoes add a sweet-tangy bite that balances everything beautifully. Serve it with a sprinkle of extra Parmesan or fresh basil if you’re feeling fancy.

What to Serve with Creamy Pesto Chicken Pasta Bake

Pair your Creamy Pesto Chicken Pasta Bake with a crisp side salad like this Greek Pasta Salad or some garlic bread to scoop up every bit of that sauce.

Key Tips for Making Creamy Pesto Chicken Pasta Bake

1. Use quality pesto. A good pesto makes or breaks this dish—fresh basil pesto (homemade or from the refrigerated section) has brighter flavor than jarred shelf versions.
2. Don’t overcook the pasta. Stop at al dente since it continues to cook in the oven.
3. Broil carefully. Watch the cheese—it can brown quickly.
4. Customize it. Add mushrooms, roasted red peppers, or even switch the chicken for shrimp.
5. Balance the sauce. If it’s too thick, add a splash of pasta water; if too thin, simmer it longer.
