Preheat oven to 375 degrees Fahrenheit. Spray non-stick spray on a baking sheet.
In a small bowl, combine olive oil, red crushed pepper flakes, garlic powder, and cayenne powder.
Place chopped broccoli into a large bowl and evenly pour in the olive oil mix. Distribute evenly over broccoli and gently mix until broccoli has been coated.
Evenly spread broccoli on baking sheet leaving space in between.
Roast broccoli for 8 to 10 minutes. Remove broccoli from oven and flip broccoli and evenly sprinkle almonds. Roast for an additional 8 to 10 minutes (or until desired doneness).
Once broccoli is out of the oven, sprinkle with parmesan cheese and salt.
Complete the dish by topping the broccoli with lemon zest and lemon juice. Serve and enjoy!
