A few questions we always get about this simple roasted broccoli recipe:

Does broccoli have protein?

Does it ever!  At around 4g of protein per cup, it’s in the top 10 for veggies that offer a good protein:calorie ratio.  However you’re probably not going to get your full RDA of protein just from broccoli… that would take around 20 cups.

How many carbs in broccoli?

A cup of broccoli averages between 4-6 grams net carbs per serving.  Broccoli is non-starchy, all you keto people can eat it without worrying about throwing yourself out of ketosis.   Dark, leafy vegetables like broccoli are another staple of the ketogenic lifestyle… so yes, you can have keto broccoli.  😊

How long does roasted broccoli last?

After cooking, broccoli stored in the fridge in an airtight container will last up to 3-5 days.  If you want to freeze it instead, it can last up to 10 months in an airtight freezer bag before it will start to lose its flavor.
