How to Make Poppy Seed Chicken Casserole Recipe
Step 1: Prepare Your Oven and Mixing Bowl
Start by preheating your oven to 350°F (175°C) so it’s nice and hot when your casserole is ready to bake. Meanwhile, grab a large mixing bowl for combining your creamy ingredients—this makes assembly quick and easy.
Step 2: Whisk Together the Creamy Sauce Base
In your large bowl, mix the cream of chicken soup, sour cream, mayonnaise, Dijon mustard, garlic powder, onion powder, and poppy seeds until everything is smooth and well combined. This sauce is where the magic happens, blending tangy, savory, and nutty notes that elevate the chicken beautifully.
Step 3: Add the Shredded Chicken and Season
Gently fold in the shredded chicken, making sure each piece is coated with the luscious sauce. Don’t forget to season with salt and pepper to your taste—it’s the little tweak that makes the flavor pop.
Step 4: Spread the Mixture into Your Casserole Dish
Grease a 9×13-inch casserole dish to prevent sticking, then spread the chicken mixture evenly inside. This even layer ensures every bite has the perfect balance of creamy filling and chicken.
Step 5: Make the Crispy Topping
In a small bowl, combine crushed Ritz crackers with the melted butter. This buttery, crunchy topping adds textural contrast and golden color that makes the casserole irresistible.
Step 6: Add the Topping and Bake
Sprinkle the buttery cracker mixture evenly over the chicken. Pop your casserole into the oven and bake for 30-35 minutes until the topping is gorgeously golden brown and the filling is bubbling hot.
Step 7: Serve and Enjoy!
Remove the casserole from the oven and let it cool slightly before serving. This hearty, comforting dish is best enjoyed hot, making it feel like a warm embrace on any day.
