How can I get brussels sprouts really crispy?

I’m fairly new when it comes to cooking and I’m trying to learn the basics. I love Brussels sprouts but I can never get them to have the texture I really like. When I go to restaurants they’re so crispy and flavorful, nothing like the mushy mess I get at home.

I’ve been tossing them in olive oil with salt and pepper and just baking them in the oven. Is there a way I can get them crunchy? Pan frying? Should I boil them a little first?
