I think this has been the year that has proven to my husband and I that no matter how prepared we are, no how many menus we plan out, sometimes life has other plans. There has never been a year when we need fast and easy dinners more.

This Chicken Alfredo Casserole made so easy with Knorr Pasta Sides is just such a recipe. Knorr sides are so easy to keep on hand. With just a few other simple ingredients you are able to throw together a meal that your kids will love. This Chicken and Rice Casserole was a hit and so was this fast Taco Casserole!

Keeping Knorr sides on hand makes it so easy to have dinner wins. They make these fast skillet meals possible, and they are the perfect sides for dishes like my Baked Chicken Thighs or my Chicken Tacos! This month at Meijer you can get everything you need for these fast dinners, plus if you use your mPerks you’ll be able to Buy 4 and get 1 Knorr side free. Cheers to always having these dinners in your back pocket!

READER REVIEW

“You recipes are consistently great, but last night’s Chicken Alfredo Casserole was an over-the-top, OMG, best-ever, head of the requested list, HIT! Thanks so much for a fantastic meal during a tough week.”

How to Make Alfredo Chicken Casserole

It doesn’t get much easier than this fast chicken Alfredo.

  1. Cook chicken in a skillet.
  2. Add in milk, chicken stock, and the Knorr Alfredo Pasta Sides.
  3. Simmer for 7 minutes.
  4. Top with cheese and pop it in the oven for a few minutes.

I like to take this easy dinner over the top by adding more fresh Parmesan, diced tomatoes, and parsley.

Cooking the Chicken

One of the keys to this recipe is how we cook the chicken. We are cutting it into bite sized pieces. I love cooking chicken this way because it makes it so easy for my kids to eat dinner.

Because the pieces of chicken are so small, it will be easy for them to get overcooked. To prevent that, we are going to cook them in the oil for just two minutes before we add in the pasta. The chicken will finish up cooking with the rest of the dish, making it perfectly moist at the end.

Shredding Cheese

This recipe calls for both Parmesan and mozzarella cheese. I highly recommend that you shred your own cheese. Not just for this recipe, but for all recipes. Pre shredded cheese does not melt the same way that block cheese does. Since this is such a fast meal, take the extra few minutes to shred your own.

Toppings and Add Ins

I like topping this recipe with diced tomatoes, extra shredded Parmesan, and some fresh parsley. You could also throw in a little broccoli at the beginning with the chicken for some added vegetables. Or you could wilt some spinach at the end of this recipe before topping it with cheese. That would be delicious too!

    It look yummy although I would have to tweak it just a little. I only use whole wheat flour and noodles. So I would have to make my own mix, and buy whole wheat noodles for the recipes.

    You recipes are consistently great, but last night’s Chicken Alfredo Casserole was an over-the-top, OMG, best-ever, head of the requested list, HIT! Thanks so much for a fantastic meal during a tough week. Whatever form your Thanksgiving is taking, I wish you joy. Stay safe!
    p.s. I’m trying the Brined Turkey Breast tomorrow and expect another show stopper!

      I’m so happy to hear this, Sheri! I hope the turkey is as big of a hit!

    My husband and I loved it!

    • Lisa Longley says

      I’m glad to hear that!

  4. Jess says

    Do you think you could bake this in the oven?

    • Lisa Longley says

      I do not. Because you are working with a pre packaged mix, you really need to stick to those instructions.

  5. Rebecca Donner says

    Do you have to cook the pasta directed on package first or

    • Lisa Longley says

      Just follow the directions exactly as written. So in step 2 you add the Knorr packet with the milk and chicken stock and that is when the past starts to cook.

  6. Launa Simpson says

    I made this with the chicken flavored broccoli fetttucine and boiled broccoli version instead of alfredo and cooked chicken in cubes! Its easy to follow this recipe for different combinations

  7. Zquirp says

    Np where in this recipe does it indicate an oven temp to bake at.

    • Lisa Longley says

      This is a stove top meal.

  8. Natalie Cooper says

    This was a great recipe. My family loved it! I used my 12 inch cast iron skillet and made a double batch. After the noodles were done, I topped it with cooked broccoli (2 frozen, cooked bags) and double the two cheeses.
    I wish I could post a picture here so everyone could see the melty, browned cheese!

    • Lisa Longley says

      I’m so glad you liked it!

  9. Eva Kinnaird says

    Followed recipe exactly. This was perfect after a long day!! Hubby literally just bought the Alfredo noodles packet today as a side to whatever I could make for dinner. I checked out recipes for using in a meal, and I found you! 😁 It was definitely a hit for us both. His health conditions require cut up (cubes/small pieces) of meats and soft to chew foods. He was able to eat a big plate of this. Thank you for sharing!

    • Lisa Longley says

      I’m so happy this worked for you!
