pulling a slice of chicken Alfredo casserole out of a dish

Are keto casseroles a staple in your household, too?

Casseroles can be so simple yet so delicious. Using shredded chicken and Lina’s alfredo sauce, this dish is already mouthwatering, but when you add cheese and veggies to the mix… OH MY! This is a great comfort food meal!

Tips for making the best keto chicken alfredo casserole:

  • This is an easy casserole to make ahead of time and freeze for a busy weeknight.
  • Not a fan of spinach? No worries! Just add your favorite vegetable to the dish – for example, broccoli is a great alternative. You could even swap the spinach and throw in some zoodles! Zoodles really do make me forget about pasta, so they would be a great substitution in this casserole. YUMMO! I think next time I might try substituting the spinach for Palmini noodles – that might really be a game-changer!
  • If you want to speed up the time for this recipe, you can buy pre-shredded chicken or even grab a rotisserie chicken from Sam’s or Costco.
  • I always make a Crock-Pot full of chicken at the beginning of the week and then use it throughout the week to make different dinners. It’s definitely a big time saver on busy weeknights! Another option is to boil your chicken like we did when making this amazing casserole.
  • Did you know that you can use your mixer to shred chicken? It’s super easy to do! I just throw the chicken into my KitchenAid mixer with the paddle attachment on, set it to low for about a minute, and mix. Easy peasy, and it’s perfectly shredded without having to do it by hand.

Dinner is served!

This keto chicken alfredo may be my new favorite low-carb casserole. 😋 It’s full of rich, creamy goodness from the cheese and the sauce. My husband likes to take some of the leftovers to work the next day for his lunch and it reheats beautifully. I like to throw on a little bit of ground pepper and some parmesan cheese for an extra kick of flavor when having leftovers.

    Hi there how many grams weight is the bag of frozen riced cauliflower? We have 250 & 300 gram containers of it.

  2. Yadira

    How many ounces for the cauliflower? I have a big bag from Costco! Or how many cups?

    • Ashley (Hip2Save Sidekick)

      I used a 10oz. bag which is about 3 cups.

  3. Jenifer

    This was a hit at our house! Delicious!

    • Ashley (Hip2Save Sidekick)

      Thanks, Jenifer! I’m so glad to hear.

  4. Lorimezell

    Could you omit the cauliflower, or is there something else I could substitute? My husband isn’t a fan.

    • Amber (Hip Sidekick)

      Yes! We have also liked this with broccoli! Hope that helps!

    • Laquettia

      I used spaghetti squash.

  5. Karen

    Do you need to thaw the riced cauliflower first and or drain out any excess liquid?

    • Ashley (Hip2Save Sidekick)

      Hey Karen, you do not need to thaw out the cauliflower. The excess liquid is the perfect amount for the dish. Just throw it in and go 🙂

  6. Kimberly

    Do you cook the spinach first?

    • Amber (Hip Sidekick)

      Nope! Be sure to mix in as pictured and listed above. Hope that helps!

    What can I use in place of heavy cream ? I don’t like it at all. Also I’m doing keto do can not do regular milk

      Hi Adrin! We have also made this with broccoli! Hope that helps!

  12. Kaitlyn

    Hello! I do not know much about cooking at all, hahaha, so I was wondering, how do you make your chicken in the crock pot at the beginning of the week? I would love to do this, but have no clue where to start on cook times, seasoning, etc. Thanks!

    • Amber (Hip Sidekick)

      Hi Kaitlyn! You can cook your chicken on low for 8 hours. It can be seasoned with salt and pepper or any favorite seasoning you prefer, for example taco seasoning. Hope this helps!

      Hi Maddie! This recipe makes 8 servings. Hope that might help!

    What is the sodium content per serving on this recipe, my husband has to watch his salt intake?

    • Amber (Hip Sidekick)

      Hi Lynda! When we plugged in the numbers on MyFittnessPal it was 903mg for the sodium. Hope this helps!

  20. Becky

    Can I leave out the spinach too much vitamin K for me

    • Amber (Hip Sidekick)

      Yup! You could leave that out. It should still be yummy, however it will change the nutritional values a bit.

      • Tonya

        Thank you

  23. Kathy

    Delicious. I used 3 big cans of chicken from Costco. Served it to 8 women in my bible study group and they loved it. This is the 2nd recipe of yours that I have tried and have loved them both. I will keep trying more recipes. I am so glad I discovered your website.

    • Jennifer (Hip Sidekick)

      We are so glad you found us, too! I’m so happy to hear your group loved this casserole. Have a great day, Kathy!
