Add the spinach to a large mixing bowl. Be sure to thaw completely and squeeze out any excess liquid. Use a fork to break up the spinach pieces and any large clumps.
Step 2
Finely dice the onion. Add the onion to the bowl along with the garlic powder, nutmeg, cranberries, cream cheese, mayonnaise and parmesan. Crumble over the blue cheese. Mix well to combine.
Step 3
Preheat the oven to 400 degrees Fahrenheit. Spoon the spinach dip mixture into a medium oven dish in an even layer. Transfer to the oven to bake for 15 minutes.
Step 4
Remove the dip from the oven. Crumble the walnuts over the surface of the dip. Return to the oven for a further five minutes to toast the walnuts. The dip should be golden on top and bubbling. Allow to cool a little before serving with your favorite low carb dippers.
