Macaroni Casserole

This recipe made a delicious flavorful supper! 5 stars from the hubby too!
I followed the recipe almost exactly. Alterations - The package of diced ham was more like 1 cup and I used all of it. Instead of grating a fresh onion I used dehydrated onion (2 T) that I reconstituted. Seemed like a lot of trouble to grate an onion and the dried ones worked great. I forgot to withhold 2T butter for the panko so it ended up with a bit more butter than the recipe called for. I used Siracha for hot sauce. At the end I sprinkled my unseasoned panko with S&P, garlic mix.
I don't think I will change anything when I make this again. But I might double the spinach and the nutmeg. It will be interesting to see how the flavors settle in and how the seasonings meld together tomorrow. This makes a great comfort supper.
