Preheat the oven to 375 degrees and grease a casserole dish with non-stick cooking spray or butter and set aside.
Begin by working with the thawed spinach. Use fresh paper towels to squeeze out all of the excess water until they are as dry as possible.
Next add butter to a large pan over medium heat.
Once heated add onion and saute until tender (about 3-4 minutes). Then add garlic and saute for about 30 seconds.
Stir in flour and cook for about a minute.it will become a thick paste.
Whisk in half and half and then add onion powder, Italian seasoning, garlic powder, nutmeg and cayenne. Stir in cream cheese, 1/3 cup of parmesan and 1/4 cup of Italian blend cheese and allow it to completely dissolve into the cream.
Finally add in the spinach and stir into the cream sauce. Season with salt and pepper to taste and continue stirring for about 3-4 minutes until spinach is heated through and one with the sauce.
Taste one last time, do final seasoning and pour spinach mixture into the greased casserole dish.
Sprinkle the top with remaining cheeses and panko crumbs. Bake for 15-20 minutes or until the cheese is melted, golden and bubbly and panko crumbs are golden. Serve warm.

Marina on 2023-12-21 (5 stars): This spinach gratin is divine! I was torn between this recipe & your creamed spinach which are essentially the same except for more cheese & baked with the panko. I am kind of particular about creamed spinach spinach/gratins and your recipe is hands down the best I have ever tasted and made. Thank you!
Mary Joy on 2023-02-16 (5 stars): This Spinach Gratin looks absolutely delicious! I love the combination of spinach, cheese, and breadcrumbs, they all work together so well. The use of cheese on top is especially enticing, and I'm sure the creaminess it adds to the dish is truly exceptional! This recipe looks like it's simple enough to make, yet complex enough to really impress. This dish is bound to be a hit with family and friends alike! I'm so excited to try it.

Mirlene on 2022-01-19 (5 stars): I'll be making this spinach gratin for sure for my family. I have never had any type of gratin except with potatoes.
Cara on 2022-01-19 (5 stars): Um, yes to everything going on here. The cheesy, the creamy the gratin-y, this recipe is to die for.
Beth on 2022-01-19 (5 stars): I'm with you that broccoli and cheese belong together! I know this is a dish to share but I'm sure I could eat this dish all on my own!
