The Creamiest Chicken Casserole Ever – And So Easy!

If you’re only interested in making this creamy chicken casserole in the easiest way possible, then you’ll need to start out by simply adding your chicken breast meat into a large bowl along with one cup of frozen peas, one can of cream of mushroom soup, and one cup of sour cream. I like to add the frozen peas in for two main reasons — they’re one of my favorite foods to begin with and they’re a good source of antioxidants that may be helpful in preventing certain diseases.

On the other hand, if you’d like to make sure that your casserole is as flavorful as possible, I would recommend adding in a bit of chopped onion and garlic cloves as well. I use garlic and onion in TONS of my recipes, and it’s all because of the immense amount of flavor they provide. On top of that, they’re incredibly good for you, with research indicating that they’re also quite useful in helping to prevent cancer. (2)

After mixing all of your ingredients together, season it with a bit of salt and pepper before transferring it all into a large baking dish. At this point, you can feel free to add yet another optional ingredient in the form of one cup of shredded Cheddar cheese. I strongly recommend you do so — it adds even more flavor to the casserole along with a solid amount of added protein and saturated fat.

Next, you’ll want to top the mixture with one cup of shredded Ritz crackers (I love Ritz crackers to begin with so it only made sense to use them in a delicious casserole recipe!) and ¼ cup of melted butter. If I could make yet another recommendation, it would be that you use grass-fed butter when making this recipe — as well as any of our other recipes that call for butter. Compared to grain-fed butter, it’s a much better source of heart healthy omega-3 fatty acids and antioxidants. (3)

All that’s left to do is simply bake your casserole in the oven at 350°F for 25-30 minutes, just long enough for the casserole to be bubbly and have the crumbs turn golden brown. Pull it out of the oven whenever that happens, allow it to cool off slightly, and then get ready to enjoy one deliciously creamy chicken casserole!
