Prep notes
Have your tortellini refrigerated or fully thawed if you’re using previously frozen packages. Cut the chicken into 1-inch cubes so it cooks through quickly and evenly. Measure the pesto and cheeses in advance so assembly moves quickly. Preheat the oven to 375°F before you finish the stovetop steps so the bake goes straight into a hot oven.
Step-by-step instructions
- Preheat and season: Preheat the oven to 375°F. Pat the 1 pound of boneless, skinless chicken breasts dry and season lightly with salt and pepper.
- Sear the chicken: Heat 1 tablespoon butter in a large oven-safe skillet over medium-high heat. Once the butter is melted and shimmering, add the cubed chicken in a single layer. Cook without moving for 2–3 minutes to develop color, then stir and continue cooking until the chicken is no longer pink in the center, about 4–6 more minutes total depending on cube size. Transfer the cooked chicken to a plate and set aside.
- Soften the vegetables: In the same skillet, add the chopped 1/2 red onion and the chopped 1 red bell pepper. If needed, add a tiny splash of additional butter or a teaspoon of oil. Sauté over medium heat until the onion is translucent and the pepper is tender, about 4–5 minutes, stirring occasionally.
- Create the sauce base: Pour in 2 cups chicken broth and 1 cup heavy cream, stirring to scrape up any browned bits from the bottom of the skillet. Bring the mixture to a gentle simmer over medium heat.
- Add pesto and spinach: Stir in 6 ounces basil pesto until fully incorporated into the cream and broth. Add 2 cups fresh baby spinach and cook until wilted, about 1–2 minutes.
- Combine chicken and tortellini: Return the cooked chicken to the skillet and add the 40 ounces cheese tortellini (refrigerated or thawed). Stir gently to coat the tortellini and chicken with the sauce, ensuring the tortellini are nestled evenly in the pan.
- Add the cheese: Sprinkle 2 cups shredded fontina cheese evenly over the top of the tortellini and sauce. Then sprinkle 1/2 cup shaved Parmesan cheese over the fontina. Season with additional salt and pepper to taste, keeping in mind that both pesto and Parmesan add saltiness.
- Bake until bubbly: Transfer the oven-safe skillet to the preheated oven. If you used a regular skillet, transfer the full mixture to a 9×13-inch baking dish before placing it in the oven. Bake at 375°F until the cheese is melted, bubbling, and lightly golden on top, about 18–22 minutes. If desired, broil on high for 1–2 minutes to deepen the top color; watch carefully to prevent burning.
- Rest and serve: Remove the bake from the oven and let it rest for 5 minutes to set. Spoon portions onto plates, garnish with an extra sprinkle of shaved Parmesan or a few torn basil leaves if you like, and serve warm.
Troubleshooting and tips
- Cheese melt: If your fontina doesn’t melt evenly, cut the cheese into smaller shreds next time so it spreads and melts quickly.
- Too thin sauce: If the sauce seems thin after baking, let the finished dish rest a few extra minutes while the sauce thickens as it cools. For a thicker sauce next time, reduce the chicken broth by 1/4 cup.
- Spice it up: Add a pinch of red pepper flakes while sautéing the onions and peppers for subtle heat.
- Make-ahead: Assemble the bake through step 7, cover tightly, and refrigerate for up to 24 hours. Bake straight from the fridge, adding 8–10 extra minutes to the baking time.
Serving ideas
This Chicken Pesto Tortellini Bake is hearty on its own but pairs beautifully with a crisp green salad dressed with lemon vinaigrette, roasted vegetables, or crusty bread to mop up any leftover sauce. For a lighter accompaniment, serve with a simple arugula salad tossed with olive oil, lemon juice, and a few shaved Parmesan ribbons.
Storage and reheating
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in a 350°F oven covered with foil until warmed through, about 15–20 minutes, or reheat individual portions in the microwave. Add a splash of cream or broth while reheating if the sauce has thickened too much.
Make it your own
Feel free to switch up the vegetables to suit what’s in your fridge. Sliced mushrooms, zucchini, or sun-dried tomatoes would all play nicely here. Swap fontina for mozzarella or provolone for a different melting profile, or mix in a cup of cooked peas for pops of sweetness. The pesto is the flavor anchor, so if you love that bright basil note, don’t be shy with the 6 ounces.
Notes on ingredients
40 ounces of cheese tortellini provides the perfect ratio of pasta to sauce and chicken for this recipe. Using refrigerated or fully thawed tortellini prevents excess water in the sauce while baking. The combination of chicken broth and heavy cream creates a silky, lightly sauced casserole that complements rather than overwhelms the pesto and cheeses.
Final thoughts
This Chicken Pesto Tortellini Bake is a delightful balance of comfort and freshness — creamy, cheesy, and quick enough for a weeknight but special enough for guests. The pesto lifts the dish with herbaceous brightness while the fontina and shaved Parmesan deliver that satisfying cheesiness. Make it when you want a fuss-free, flavorful meal that comes together with ingredients you likely already keep on hand.
Enjoy, and don’t be surprised if this one becomes a regular in your dinner rotation.

Method
- Preheat the oven to 400°F (200°C).
- Melt the butter in a large skillet over medium heat, then add the chopped red onion and sauté for 2 minutes.
- Add the chopped red bell pepper to the skillet and sauté for an additional 2 minutes, then remove from heat.
- Place the tortellini in a 9×13-inch (3-quart) baking dish. Add the cubed chicken, fresh baby spinach, and the sautéed onions and peppers. Toss gently to combine and spread evenly in the dish.
- In a bowl or measuring pitcher, whisk together the basil pesto, chicken broth, heavy cream, 1 teaspoon salt, and 1/2 teaspoon ground black pepper until smooth.
- Pour the pesto-cream mixture evenly over the tortellini and chicken in the baking dish.
- Cover the baking dish with foil and bake for 20 minutes.
- Carefully remove the foil and gently stir the pasta so the top pieces are coated with sauce. Sprinkle the shredded fontina and shaved Parmesan evenly over the top.
- Return the dish to the oven and bake uncovered for 15–20 minutes more, until the cheese is melted and the casserole is bubbly. Serve warm.
Notes
- This recipe can be halved and baked in an 8- or 9-inch square pan for a smaller batch.
- You can add the onions and peppers raw to the baking dish for a true one-pan version, but sautéing them first improves flavor and texture.
