Ingredients You'll Need
Each ingredient in this casserole pulls more than its weight, so quality counts. Start with refrigerated (not dried) cheese tortellini; the filling keeps the pasta from tasting starchy after baking. If you only have dried, boil for 2 minutes less than package directions before assembling.
Rotisserie chicken is my week-night love language, but any cooked chicken—poached breasts, leftover grilled thighs, even Thanksgiving turkey—works. Remove skin, then shred into bite-size ribbons so every forkful has that savory-sweet roast flavor.
The sauce’s backbone is cream cheese; use the full-fat block, not the whipped tub. Whipped contains extra air and can separate under heat. Let it soften on the counter while you prep vegetables; it melts into the broth faster and silkier.
Spinach wilts in seconds, so grab fresh baby leaves. Frozen spinach is fine—thaw and squeeze until bone-dry or the casserole will weep. For sun-dried tomatoes, oil-packed give supple chew and a tangy sweetness. If yours are dry, rehydrate in hot water for 10 minutes, then pat dry.
Panko breadcrumbs mixed with melted butter and Italian seasoning create the crackly lid. If you’re gluten-free, pulse a cup of rice Chex with parmesan; the crunch is uncannily similar.
How to Make Creamy Chicken and Tortellini Casserole for Dinner
Preheat & Butter
Set oven rack to center position and preheat to 400 °F (204 °C). Generously butter a 9×13-inch (3-quart) ceramic or enamel baking dish; ceramic retains gentle heat so the edges don’t scorch. Buttering instead of spraying lets the breadcrumbs brown with nutty flavor.
Sauté Aromatics
In a large skillet over medium heat, melt 2 Tbsp butter. Add 1 cup diced yellow onion and cook 3 minutes until translucent. Stir in 3 minced garlic cloves and ½ tsp each kosher salt and black pepper; cook 30 seconds until fragrant but not brown. The salt jump-starts onion’s natural sugars for subtle sweetness.
Create Quick Cream Sauce
Reduce heat to medium-low. Add 8 oz cubed cream cheese and 2 cups low-sodium chicken broth. Whisk constantly until cream cheese melts into a smooth, thick sauce, about 4 minutes. Whisk in 1 cup half-and-half, ¼ cup grated parmesan, 1 Tbsp Dijon mustard, ½ tsp dried thyme, and pinch nutmeg. Simmer 1 minute; the mustard marries dairy with chicken while nutmeg amplifies savoriness.
Fold in Chicken, Tortellini & Veggies
Remove skillet from heat. Stir in 3 cups shredded cooked chicken, 1 lb refrigerated cheese tortellini, 3 cups loosely packed baby spinach, and ½ cup sliced sun-dried tomatoes. The residual heat wilts spinach perfectly without turning army-green.
Transfer & Top
Pour mixture into prepared dish, scraping every creamy drop. In a small bowl, combine ¾ cup panko, ¼ cup grated parmesan, 2 Tbsp melted butter, and ½ tsp Italian seasoning. Sprinkle evenly over casserole; don’t press down—air pockets between crumbs encourage browning.
Bake Until Golden
Bake 20–22 minutes until sauce is bubbling around edges and topping is deep golden brown. If after 18 minutes the top isn’t bronzed, switch to broil for 1–2 minutes, watching closely. Rest 10 minutes; sauce thickens as it cools and pasta absorbs excess moisture.
Garnish & Serve
Sprinkle with 2 Tbsp fresh parsley and extra parmesan shavings for restaurant flair. Serve directly from the baking dish with crusty bread to swipe the garlicky cream.
Expert Tips
Thermometer Check
Center of casserole should reach 165 °F; carry-over heat will push it to 170 °F while resting, ensuring food safety without rubbery chicken.
No Curdle Zone
Avoid boiling the cream sauce; once half-and-half is added, gentle heat keeps proteins from seizing and sauce satiny.
Crunch Upgrade
Swap half the panko for crushed Ritz crackers for buttery indulgence reminiscent of grandma’s pot-luck best.
Al Dente Insurance
Under-cook tortellini by 1 minute if you plan to freeze; it finishes cooking during bake so it won’t mush.
Spice Layer
Add ¼ tsp smoked paprika to the sauce for campfire depth without liquid smoke’s acrid edge.
Dish Swap

Variations to Try
-
Mediterranean: Swap sun-dried tomatoes for ½ cup chopped artichoke hearts, add ¼ cup crumbled feta to topping, and replace thyme with dried oregano.
-
Tex-Mex: Use pepper-jack tortellini, sub 1 cup broth with salsa con queso, add 1 cup roasted corn and 1 tsp cumin. Top with crushed tortilla chips.
-
Mushroom Lover: Sauté 8 oz sliced cremini mushrooms with onions until browned; deglaze with 2 Tbsp sherry before adding cream cheese.
-
Lightened Up: Replace half-and-half with evaporated skim milk, use Neufchâtel cheese, and add 1 cup steamed broccoli florets for bulk without calories.
-
Seafood Spin: Swap chicken for 1 lb cooked shrimp or crabmeat; fold in gently to keep seafood nuggets intact and bake only 15 min to prevent rubbery texture.
Storage Tips
Refrigerate: Cool leftovers within 2 hours. Transfer to airtight container; store up to 4 days. Reheat single portions in microwave at 70 % power with a splash of broth to loosen sauce.
Freeze Unbaked: Assemble through Step 5, wrap entire dish tightly with plastic then foil, label, and freeze up to 2 months. Bake from frozen, covered with foil, at 375 °F for 45 minutes, then uncover and bake 15 minutes more until center is 165 °F.
Freeze Baked: Divide cooled casserole into meal-size freezer bags, press out air, freeze flat up to 2 months. Thaw overnight in refrigerator; reheat in 350 °F oven 20 minutes or microwave as above.
