Preheat the oven to 400°F. In a small bowl, stir together the breadcrumbs, Parmesan, and garlic powder. Set aside.
Place the butter and olive oil in a mixing bowl. Microwave for 1 minute to melt the butter. Add the broccoli to the bowl and toss to coat.
Sprinkle the broccoli generously with the breadcrumb mixture. Toss again to coat. Spread the broccoli across a baking sheet. Roast for 15-20 minutes until tender crisp and lightly browned.
Taste the broccoli and add sprinkle with salt, only if needed.
Notes
Panko breadcrumbs are my go-to choice for this recipe, however, the recipe will also work nicely with traditional breadcrumbs. Parmesan can be a salty cheese, so I recommend waiting to season this with salt after it comes out of the oven and you've tasted the broccoli to determine if it is needed.
