Can I use low-fat dairy?

You can, but I don't recommend it. Low-fat dairy isn't appropriate for a keto diet, and doesn't taste as good.

Can I Use Store Bought Ranch Dressing?

Absolutely! Make sure you read the labels to avoid hidden sugars. This is my go to brand.

Variations

You can substitute broccoli florets for the spinach. I recommend blanching it first. To do this, bring a large pot of water to a boil. Fill a bowl with ice water. Cook the broccoli for 90 seconds and drain. Immediately plunge the broccoli into the bowl of water. Drain and continue with the recipe as directed.
Cauliflower florets are another option. Follow the same directions as you would use for spinach.

Notes

Store leftovers in an airtight container in the fridge for up to three days.

Reheating

You can reheat it in the microwave, but I am not a fan of the taste of chicken that has been cooked in the microwave. I would heat it for about 15 minutes in a 350-degree oven. You can also put it in a 300 degree Air Fryer for about 12 minutes. (Obviously, put it in a pan in your air fryer - not directly on the basket.)

Freezing

Yes - you can assemble it and leave the cheese off and freeze it for up to three months. Cooked leftovers may also be frozen in individual portions.
