Heat oven to 400F. Pierce potatoes several times with a fork and place directly on oven rack.
Bake 45-60 minutes until tender when pierced and skin feels crisp.
While potatoes bake, steam broccoli florets 4-5 minutes until bright green and tender.
Drain broccoli well and chop into small pieces.
In a medium saucepan, melt butter over medium heat.
Add flour, onion powder, and garlic powder. Whisk constantly for 1 minute.

Stir constantly until mixture boils and thickens, 3-4 minutes.
Reduce heat to low and stir in cheddar cheese until melted and smooth.
Fold in chopped broccoli and adjust seasoning.
Cut open each baked potato and fluff flesh with a fork.
Top with warm broccoli cheese sauce and serve immediately.
