Creamy Broccoli Chicken Alfredo Casserole

Broccoli Chicken Alfredo Casserole is an easy weeknight dinner packed with flavor! This creamy casserole comes together quickly and can be prepped ahead for busy nights.

I’ve been looking for recipes that are freeze ahead friendly and also easy to scale for cooking for two people. This one was a new one to me, and it turned out so well! It uses just a few ingredients and is delicious either baked the same night as it’s assembled, or you can freeze it to bake on another day. You can use rotisserie cooked chicken and frozen broccoli if you need some convenient helpers for this quick recipe!

Helpful Tips When Making This Recipe

• Use Pre-Cooked Chicken & Jarred Alfredo sauce for convenient time saving ingredients for this recipe. I like to use the Dutch Oven Chicken recipe when I’m doing batch cooking for the freezer. It is so quick and easy to bake and use for recipes like this.
• Stir the layers together to make sure the chicken and broccoli are all covered well with the sauce. Then sprinkle the cheese on last.
• Blanch the fresh broccoli before putting into the casserole. To do this, place the fresh, trimmed broccoli in a pot of boiling salted water. Cook it just until it turns dark green (just a few minutes). Immediately drain it and rinse it with cold water to stop it from cooking any longer. You don’t want it to turn mushy!

Side Dishes to Serve with This Recipe

• Cook up your favorite pasta and spoon this over the top. It’s so delicious!
• A green salad is a perfect combination with this alfredo recipe.
• Fresh bread or garlic toast pairs wonderfully.
