Line a sheet pan with aluminum foil and set it on the bottom rack of your oven. Leave the pan in the oven while it preheats to 450º F.
Once the oven is preheated, take the broccoli out of the freezer and empty the whole bag into a large mixing bowl. Add the oil, sugar, and spices to the bowl. Use your hands to toss the florets, coating thoroughly.
Remove the sheet pan from the oven and set it on a sturdy surface. Add the broccoli to the sheet pan and spread evenly. (The broccoli should sizzle when it hits the hot pan.) Try to arrange the florets so the flattest part of the stalk is facing down on the pan.
Place the pan back in the oven and bake for 15 minutes or until the edges of the florets begin to brown. Remove the pan from the oven and switch to the broiler setting.
Sprinkle salt over the broccoli. Top with liquid amino acids and grated parmesan (totally optional, but highly recommended). Return to the top rack of the oven for 1-2 minutes.
Remove from the oven and sprinkle broccoli evenly with lemon juice. Serve immediately.
