Cut broccoli florets into bite-size pieces and place them on a sheet pan spread out evenly.
Pour avocado oil over the broccoli pieces.
Sprinkle broccoli with salt and pepper. Toss to combine.
Bake for 12 - 22 minutes (varies based on the size of florets), or until desired char and crispiness.
Remove from oven and sprinkle roasted broccoli with Parmesan cheese.
Notes
Cut your florets in a similar size: Keep them about the same size so that they cook at the same rate. If they are different sizes, the smaller ones may burn while larger pieces are undercooked.
Don't overcrowd the broccoli on the sheet pan: If the florets are too close together, they will steam in the oven, and they won’t get those crispy brown edges. Make sure to spread the florets in an even layer with some space between each one.
Cook Time Varies: Keep in mind cook time may vary greatly depending on the size you cut the florets (anywhere from 12 to 22 minutes).
Alternative Coating: You can put all the cut broccoli florets in a large bowl and toss in the oil, salt, and pepper to ensure an even coating. Then, place the florets on a large baking sheet and into the hot oven.
Ways to Use the Stems: Use the florets, but julienne the broccoli stems for a broccoli salad or slaw to enjoy another day! This way you use the whole broccoli head.
