List of ingredients

12 oz. pasta of choice (tube-shaped recommended)
1 lb. boneless, skinless chicken breasts, cubed
1 Tbsp. Italian seasoning
1 tsp. paprika
1 1/4 tsp. kosher salt, divided
1/2 tsp. black pepper
1 to 2 Tbsp. extra-virgin olive oil
3/4 cup minced shallots
4 garlic cloves, minced
Pinch of crushed red pepper flakes
1 cup jarred roasted tomatoes, thinly sliced
2 to 3 handfuls fresh baby spinach
1/2 cup pesto
1/2 cup heavy cream
1/2 cup freshly grated Parmigiano-Reggiano cheese, divided
3 to 4 oz. fresh mozzarella cheese, torn
Chopped fresh basil for garnish

step-by-step instructions

Step: Boil pasta in generously salted water until just shy of al dente. Reserve 1 cup of pasta cooking water before draining.
Step: Toss chicken in a large bowl with 2 tablespoons of oil from the roasted tomatoes jar (or olive oil), Italian seasoning, paprika, 3/4 tsp. salt, and 1/2 tsp. pepper.
Step: Heat a large oven-safe skillet over medium heat. Sauté chicken until cooked through, about 8 minutes. Transfer chicken to a bowl.
Step: Add shallots to the skillet, cooking until soft (about 3 minutes). Add garlic and red pepper flakes; cook until aromatic (about 1 minute).
Step: Stir in roasted tomatoes and spinach. Cook until spinach wilts (2 to 3 minutes) and season with remaining 1/2 tsp. salt.
Step: Stir in pesto and heavy cream.
Step: Add the cooked pasta and 1/2 cup of reserved pasta cooking water. Stir until the sauce thickens and clings to the pasta, adding more water as needed.
Step: Stir in 1/3 cup of the Parmigiano-Reggiano and the cooked chicken.
Step: Preheat broiler to HIGH. Top pasta with torn mozzarella and the remaining Parmigiano-Reggiano.
Step: Broil until the mozzarella is melted and bubbly, about 3 to 4 minutes. Garnish with fresh basil and serve.

Refining Your Technique

Achieving the Ideal Pasta Texture

Because the pasta undergoes a brief broiling session, it is vital to pull it from the boiling water earlier than the package instructions suggest. If you boil the pasta until it is completely soft on the stove, it will likely turn mushy once it is baked with the sauce. Aim for a distinct bite, often called ‘al dente,’ which ensures the pasta maintains its structure under the heat of the broiler.

Selecting the Best Skillet

An oven-safe skillet is the backbone of this recipe, ideally made of seasoned cast iron or stainless steel. These materials retain heat well, which helps in getting a nice sear on the chicken cubes without steaming them. Ensure your handle is also oven-safe or protected with a silicone sleeve before you move the dish to the broiler.

Customization and Adaptations

Choosing Meat Alternatives

While chicken breast is standard, you can easily swap it for diced chicken thighs if you prefer darker, juicier meat. For those who want a different texture, sliced chicken sausages can be seared alongside the aromatics. Always ensure that any alternative proteins are cooked to the appropriate internal temperature before adding them back to the sauce to mingle with the other ingredients.

Incorporating Diverse Vegetables

Beyond spinach, you can easily add other greens like chopped kale or chard, though these will need an extra minute or two to wilt compared to baby spinach. If you have extra roasted red peppers or artichoke hearts, these can be chopped and added alongside the tomatoes. These additions provide extra texture and boost the nutritional profile of the meal without overpowering the pesto base.

Adapting for Different Dietary Needs

To keep the recipe gluten-free, simply use a high-quality brown rice or chickpea pasta, which mimics the texture of wheat pasta quite well. If you need a vegetarian version, swap the chicken for protein-rich white beans like cannellini or butter beans. Ensure that your pesto is made without any restricted animal-derived ingredients if you are following strict dietary guidelines.

Serving and Presentation

Enhancing the Platter

This pasta bake is a substantial dish that pairs beautifully with a crisp side salad featuring a light vinaigrette. The contrast between the heavy, creamy sauce and a zesty green salad provides a balanced dining experience. Serving directly from the skillet adds a rustic, approachable feel that works well for both family dinners and casual gatherings with friends.

Managing Sauce Consistency

The secret to a perfect pasta bake is the emulsion of the pasta water and cream. Never discard all of your pasta water before ensuring your sauce is at the desired thickness. The starch in the water acts as a binding agent, ensuring that the pesto-cream mixture clings to every ridge of the pasta rather than pooling at the bottom of the pan.

Storage and Reheating

Proper Refrigeration Techniques

If you have leftovers, allow the dish to cool to room temperature before covering it. Store in an airtight container for up to four days. This helps keep the pasta from drying out in the refrigerator, maintaining the integrity of the sauce for your next meal.

Reviving the Sauce When Reheating

Pasta has a tendency to absorb liquid as it sits, which can make the sauce feel stiff upon reheating. When warming individual portions in the microwave, add a small splash of water or a tiny bit of extra cream to restore that velvety texture. If reheating in the oven, cover the dish with foil to prevent the cheese and top layer of pasta from becoming overly crispy or dry.

Freezing for Later Use

This dish is an excellent candidate for meal prepping and can be frozen either before or after the broiling step. If freezing before broiling, wait until the mixture is completely cool, assemble in a freezer-safe dish, and wrap tightly. When you are ready to eat, let it thaw in the refrigerator overnight, then proceed with the broiling instructions as directed.

Common Queries Addressed

Can I use pre-grated cheese?

It is highly recommended to grate your own Parmigiano-Reggiano from a block. Store-bought pre-grated cheese is often coated in anti-caking agents that prevent it from melting smoothly into a sauce. Freshly grated cheese will create a much more uniform, silky, and flavorful result for your creamy base.

What is the benefit of saving pasta water?

Pasta water is liquid gold in this recipe because it is infused with the starch released by the noodles during boiling. This starchy water helps the pesto and cream emulsify into a cohesive, thick sauce. Plain tap water lacks these starches and will result in a thinner, more watery consistency that separates rather than clings to the pasta.

How do I prevent the garlic from burning?

Garlic has a very low smoke point and can turn bitter in seconds if overheated. Always wait until the shallots are softened and translucent before adding the garlic, and keep the heat at a manageable medium level. The garlic should only be sautéed for about 60 seconds, just until you smell its intense aroma, to ensure it flavors the oil without charring.

Can I omit the heavy cream?

While the cream provides the characteristic richness and helps dilute the saltiness of the pesto, you can substitute it with half-and-half if you want a slightly lighter sauce. Avoid using milk, as it lacks the fat content necessary to thicken properly when heated with the acidic elements of the pesto and tomatoes, potentially leading to a grainy sauce texture.
