This creamy chicken pot pie casserole is classic comfort food made easy. Tender shredded chicken, a medley of vegetables, and a buttery, golden crust combine into a family-friendly meal that’s perfect any night of the week.

This casserole captures all the flavors of a traditional pot pie but saves time and effort by layering the filling in a baking dish and topping it with a simple, buttery batter that bakes into a crisp crust. Using rotisserie or pre-cooked chicken and frozen vegetables keeps prep fast without sacrificing texture or taste. The finished dish is creamy, satisfying, and great for leftovers or freezing for later.

Why This Recipe Works
This chicken pot pie casserole streamlines a classic comfort recipe in three ways: it uses cooked chicken and frozen vegetables to cut prep time; a pantry-based creamy filling creates rich flavor with minimal effort; and a simple pour-over batter forms a buttery crust without rolling pastry. The casserole holds up well as leftovers and can be prepared ahead and frozen for a convenient meal later.

🛒 Ingredients You’ll Need

- Chicken: Rotisserie or other cooked, shredded chicken (juicy and ready to use).
- Cream of Celery Soup: adds savory creaminess.
- Cream of Chicken Soup: creates a rich chicken base for the filling.
- Chicken Broth: thins and flavors the filling.
- Cornstarch: dissolves in broth to thicken the filling to the right consistency.
- Mixed Vegetables: frozen mixed vegetables (peas, carrots, corn, green beans) hold texture well in the oven.
- Garlic: fresh minced garlic for depth of flavor.
- Salt & Pepper: to taste.
- Milk: whole or 2% milk for the crust batter.
- Self-Rising Flour: creates a light, bubbling crust (do not substitute all-purpose without leavening).
- Butter: melted, for a rich, golden crust.
📋 Variations
- Protein: Use baked chicken breasts or thighs, or substitute shredded turkey for a holiday-style casserole.
- Vegetables: A frozen mixed-vegetable blend is ideal. Avoid canned vegetables, which can become too soft during baking.
- Potatoes: Add small cooked potato cubes or roasted new potatoes for extra heartiness; cook them first to al dente before adding.
- Vegetarian option: Omit the chicken and swap chicken broth for vegetable broth; increase the vegetables for a satisfying meatless version.
🔪 Step-By-Step Recipe Instructions
- Preheat: Set the oven to 400°F.
- Prepare chicken: Shred about 4 cups of rotisserie or cooked chicken into bite-size pieces and spread evenly in the bottom of a 9×13-inch baking dish.
- Cook vegetables: Cook a 10-ounce package of frozen mixed vegetables according to package directions, drain any liquid, and spread the vegetables evenly over the shredded chicken.
- Make slurry: Whisk 1 tablespoon cornstarch into 1 cup chicken broth until dissolved and set aside.
- Mix filling: In a bowl combine 1 can cream of celery soup, 1 can cream of chicken soup, 2 minced garlic cloves, ½ teaspoon salt, and ¼ teaspoon ground black pepper. Add the chicken-broth/cornstarch slurry and whisk until smooth.
- Assemble filling: Pour the creamy mixture over the chicken and vegetables and spread evenly with a spatula.
- Make crust batter: In a medium bowl whisk together 1 cup self-rising flour, 1 cup whole milk, and ½ cup melted salted butter until smooth. The batter will be thin.
- Top the casserole: Slowly pour the batter over the filling and spread gently. It’s fine if some filling mixes with the batter at the edges—this helps create a flavorful, bubbling crust.
- Bake: Bake uncovered for 45 minutes or until the crust is golden brown and the filling is bubbly. Remove from the oven and let rest for at least 5 minutes before serving.







🙋🏼 Recipe FAQs
How do you thicken pot pie filling?
Mix 1 tablespoon of cornstarch into 1 cup of cold chicken broth until dissolved, then add to the filling mixture. This prevents a runny casserole and yields a creamy, stable filling.
Can I make this into a freezer meal?
Yes. Assemble the casserole in a disposable aluminum pan, cover tightly with foil, and freeze for up to 3 months. Thaw in the refrigerator before baking at 400°F for 45–60 minutes until heated through.

💭 Expert Tips
- Let the casserole rest 5–10 minutes after baking to allow the filling to set for cleaner slices.
- Pre-cook the frozen vegetables to remove excess water and ensure proper texture after baking.
- Use self-rising flour for the crust batter for best lift; if unavailable, mix 1 cup all-purpose flour with 1 ½ teaspoons baking powder and ¼ teaspoon salt.
- Store leftovers in a covered container for 3–4 days and reheat in the oven to preserve crust texture.
