Can’t wait to try this! Yummy!!
40 Yrs and counting on this Spinach Casserole and my family still request it as do the grandkids. You can’t go wrong making this recipe is delish and easy!!!
I agree Carolyn, this spinach casserole is a winner!
I found this recipe somewhere years ago and even put it in our church cookbook, one lady asks me to make it at every dinner! I am trying to find the nutrition information for it, as I believe it may be Keto approved, but I need to check it out. Hopefully I can find it without adding it all up!
Hi G D. This recipe would not be Keto diet approved because it has all-purpose flour in it. If you substitute the AP flour for something keto approved (maybe almond flour) it would be a great keto recipe.
Please tell me where I can find the blue and white slow cooker pictured with this recipe.
Hi MT, I believe that this pattern is now discontinued. However you might be able to find it second hand on sites like ebay or etsy. Best of luck!
