Garlicky baked panko shrimp

This is another great recipe picked up from Gimme Some Oven, who got it from Real Simple.
I made a few changes like adding a little broccoli and onion to it, and I can imagine a number of other twists with this basic template too.

Ingredients:
1 lb. raw shrimp, deveined and peeled (I used frozen cooked, thawed in refrigerator)
4 cloves garlic, minced
2 Tbsp. white wine
salt and pepper
1 cup finely chopped broccoli florets
1 cup chopped onion
garlic salt and red pepper flakes, to taste
1/4 cup (4 Tbsp.) melted butter
1/2 cup Panko bread crumbs
2 Tbsp. fresh Italian-leaf parsley, chopped (I used dried)
half of a lemon (optional)


Method:
Preheat oven to 425 degrees F.
In a bowl, combine the shrimp, garlic, and white wine. Stir to combine, then pour into a baking dish. Spread out evenly, and then season with salt and pepper.
Over medium heat, saute onion and broccoli until both are tender. Stir garlic salt and red pepper flakes into pan, then transfer mixture into baking dish with shrimp.
In another bowl, use a fork to mix melted butter, Panko, and parsley until well combined. With your fingers, sprinkle the mixture evenly in the baking dish over the shrimp.
Transfer dish to oven and bake until the shrimp are pink and opaque, about 15-18 minutes.
