This Pesto Chicken Gnocchi Bake is one of those recipes that shows up at my table whenever I want something comforting but slightly elevated. I discovered this combination on a rainy evening when I had leftover rotisserie chicken and a jar of DeLallo pesto in the fridge; the result was an immediate family favorite. The sauce is luxuriously creamy thanks to heavy cream and just a touch of white wine, while the pesto brightens every bite with basil and nuttiness. The gnocchi remains pillowy rather than gummy when treated gently, and melting a blanket of mozzarella and freshly grated parmesan on top finishes it with a golden, irresistible crust.

I love how quick this comes together: sauté an onion and garlic, add cream and pesto, stir in gnocchi and pulled chicken, then bake until bubbly. It’s the kind of dish that looks like it took hours but is genuinely simple to make. My kids call this the "green cheesy gnocchi" and ask for it at least once a month; friends always ask for the recipe after a dinner party. It’s hearty enough for a main course yet elegant enough for casual entertaining.

Ingredients

• Butter (1 tablespoon): Use unsalted butter if you prefer to control salt. It’s the flavor base for the onion and helps create a silky start to the sauce—Land O Lakes or a quality European-style butter works well.
• Onion (1/2 medium, chopped): Yellow or sweet onion provides a mild sweet foundation; chop finely so it softens quickly and blends into the sauce.
• Garlic (2 cloves, minced): Fresh garlic is essential—avoid garlic powder here. Mince finely so it releases aroma without leaving raw bits.
• Dry white wine (1/2 cup): A dry Sauvignon Blanc or Pinot Grigio deglazes the pan and brightens the cream. Use a wine you’d drink; cooking with bad wine results in bad flavor.
• Heavy/whipping cream (1 cup): Full-fat cream adds richness and helps the sauce cling to gnocchi. If you want slightly lighter, substitute half-and-half but expect less body.
• DeLallo Pesto (1/4 cup): The pesto is the flavor star—basil, pine nuts, and parmesan. Measure carefully and taste; different pestos vary in salt and oil content.
• Italian seasoning (1/2 teaspoon): A pinch to round out the herb profile—oregano, basil, and thyme complement the pesto rather than compete.
• DeLallo Potato Gnocchi (1 pound): Fresh or packaged potato gnocchi both work—follow package guidance for cooking times if boiling first. Gnocchi gives a tender, potato-forward bite.
• Cooked/rotisserie chicken (2 cups): Shredded or diced, rotisserie chicken saves time and adds savory depth. Leftover roast chicken is perfect.
• Freshly grated parmesan (1/2 cup): Use real Parmigiano-Reggiano for the nutty, crystalline saltiness that melts into the sauce.
• Shredded mozzarella (2 cups): Whole-milk mozzarella melts beautifully—buy a block and shred it yourself for best results.
• Fresh parsley (1 teaspoon, chopped): Brightens the finished dish and adds a hint of freshness when sprinkled at the end.
• Salt & pepper: Season to taste; coarse kosher salt seasons more gently than table salt—adjust accordingly.

Instructions

Preheat the oven: Set your oven to 375°F and position the rack in the top third so the cheese browns without burning. Allow the oven to fully preheat while you build the sauce so the bake goes in hot and bakes evenly. Sauté aromatics: In a deep, oven-safe skillet, melt 1 tablespoon butter over medium heat. Add the chopped half onion and sauté for about 5 minutes until it softens and just begins to brown on the edges—this caramelization adds sweetness to the sauce. Add garlic and wine: Add the minced garlic and immediately pour in 1/2 cup dry white wine. Let it come to a gentle simmer and bubble for roughly 30 seconds to cook off the alcohol and concentrate flavor; scrape any fond from the pan. Build the cream sauce: Pour in 1 cup heavy cream, then stir in 1/4 cup DeLallo pesto and 1/2 teaspoon Italian seasoning until smooth. Keep the heat moderate—bring to a gentle simmer but avoid rapid boiling which can separate the cream. Combine gnocchi and chicken: Stir in 1 pound potato gnocchi and 2 cups cooked chicken. Heat through for 1 to 2 minutes so the gnocchi warms and absorbs some sauce. If the sauce becomes too thick before the oven, add a splash more cream or 1 to 2 tablespoons water to loosen it; you want a saucy consistency since the gnocchi will continue to soften in the oven. Top and bake: Remove the skillet from heat and evenly sprinkle 1/2 cup freshly grated parmesan and 2 cups shredded mozzarella over the top. Transfer uncovered to the preheated oven and bake for about 15 minutes until bubbling. For a deeper golden top, switch to broil for 1 to 2 minutes—watch carefully to avoid burning. Rest and finish: Allow the bake to rest in the skillet for 5 minutes so the sauce settles. Sprinkle with 1 teaspoon chopped fresh parsley and season with salt and freshly cracked black pepper to taste before serving.

Storage Tips

Cool the bake to room temperature before refrigerating to avoid condensation and sogginess. Transfer leftovers into an airtight container and use within 3 days. For freezing, portion into shallow, freezer-safe containers and freeze flat for up to 2 months—thaw overnight in the refrigerator and reheat at 350°F covered with foil for 20-30 minutes, uncovering at the end to re-crisp the top. Reheat single servings in a microwave on medium power if time is tight, stirring halfway through to ensure even warming.

Ingredient Substitutions

If you don’t have DeLallo pesto, make a quick blender pesto with 2 cups fresh basil, 1/4 cup toasted pine nuts (or walnuts), 1/3 cup grated parmesan, 1/3 cup olive oil, and a small garlic clove—pulse until combined. For a lighter version, use half-and-half instead of heavy cream and reduce the cheese to maintain balance; expect a thinner sauce. Swap gnocchi for small rigatoni or shells if you prefer a pasta texture—cook pasta two minutes less than package directions so it finishes in the oven without overcooking.

Serving Suggestions

Serve this alongside a crisp green salad dressed with lemon vinaigrette to cut through the richness, or pair with roasted asparagus for a bright spring plate. Garnish with extra grated parmesan, a drizzle of good olive oil, and a few basil leaves for color. This also works well for potlucks—cut into squares and serve warm from the skillet or in a casserole dish with a side of crusty bread.

Cultural Background

Gnocchi are small dumplings with deep roots in Italian cuisine, traditionally made from potato, flour, and egg. In Italy, gnocchi are often paired with simple butter and sage or a light tomato sauce; pairing them with pesto and cream is a more modern, Anglo-Italian adaptation that emphasizes richness and convenience. Combining gnocchi with rotisserie chicken and baking with cheese reflects a home-cooking approach that blends traditional textures with contemporary, pantry-driven flavors.

Seasonal Adaptations

In spring, add halved cherry tomatoes and fresh peas for pops of color and sweetness; in fall, stir in roasted mushrooms and a handful of baby spinach. For a holiday twist, replace basil pesto with sun-dried tomato pesto and add chopped roasted red peppers for a holiday color palette. Swap the chicken for shredded turkey after Thanksgiving to turn leftovers into a cozy, familiar dinner.

Meal Prep Tips

Assemble the sauce, gnocchi, and chicken in a skillet or casserole dish and refrigerate (covered) up to 24 hours before baking. When ready to eat, top with cheeses and bake from chilled—add about 5 to 8 minutes to the bake time. Portion into individual containers after baking for grab-and-go lunches; reheat in a toaster oven or microwave and add a fresh herb sprinkle just before serving.

Whether you’re feeding a family, entertaining friends, or prepping meals for the week, this Pesto Chicken Gnocchi Bake is an approachable, crave-worthy option that rewards a few simple techniques with delicious results. Make it your own by adjusting herbs, cheeses, or proteins, and enjoy sharing it warm from the oven.
