This Broccoli Chicken Alfredo Casserole is a simple and easy one-pot meal that you can throw together in minutes. Creamy chicken and broccoli casserole is pure comfort food that the whole family will beg you to make over and over.
When you’re in the mood for a simple “throw together” one-pot meal, feast your eyes on this broccoli chicken alfredo casserole.
It goes from stovetop to oven in the same pot, which means an easy dinner and fewer dishes.
For this recipe, you’re going to need a deep pot/pan that can be used on a stove and then popped into the oven. I used my 4-quart cast iron dutch oven and it works perfectly. If you have an oven-proof saucepan, you can also use that!
And if you don’t have a cooking dish that fits the bill, you can always cook the pasta on the stovetop and then put everything in a casserole dish. It’s one extra dish to wash, but oh well.
This recipe calls for the noodles to be cooked directly in the milk for a super creamy one-pot dish.
If you want to use less milk, you can cook the pasta and homemade alfredo sauce separately. Check the printable recipe card below for details.
Pro Tips/Recipes Notes
- Stir the milk/butter/pasta mixture constantly for the 6 minutes it is cooking. This will prevent the milk from scalding the bottom of the pan. I want to make your life and thus dish duty easy peasy!
- To make this vegetarian, simply leave the chicken out. Frankly, I only add the chicken half of the time that I make this; it can definitely be a delicious meatless meal.
- I have not tested this with gluten-free pasta, but given how finicky gluten-free noodles can be, I would recommend cooking the noodles and sauce separately and then combining it with the rest of the ingredients.

Unless I’m blind, the recipe doesn’t say whether to bake this covered or uncovered, and that’s kind of important to know ahead of time. I use a dutch oven and half of the recipes call for baking with the cover on, half with it off.
Hi LB, unless specified, it defaults to uncovered. But I can noted it to clarify it. Happy cooking!
