How to cook deliciously - Classic Green Beans Au Gratin
1. Stage
Preheat the oven to 450 degrees F (230 degrees C). Generously grease a casserole dish with 1 tablespoon butter.
2. Stage
Bring a generously salted pot of water to a rolling boil over high heat.
3. Stage
Remove stems from beans by trimming with a knife or snapping them off with your fingers. Cut beans in half.
4. Stage
Add beans to the boiling water, stir, and cook until just barely tender, 5 to 6 minutes, testing often to make sure you don't overcook them.
5. Stage
Remove beans with a strainer and immediately place in a bowl of cold water to stop the cooking process.
6. Stage
Once beans have cooled to the touch, use your hands to drain and transfer them into the prepared casserole. It's okay if they're still a bit wet.
7. Stage
Season beans with pepper, salt, and Dijon mustard; mix until beans are well coated. Pour in cream, scatter Comté cheese over top, and sprinkle with Parmigiano-Reggiano.
8. Stage
Combine melted butter and bread crumbs in a small bowl. Stir until well combined and mixture resembles wet sand. Spoon and sprinkle bread crumbs over the casserole, then dust with cayenne.
9. Stage
Bake in the center of the preheated oven until browned and bubbly, 15 to 20 minutes.
10. Stage
Let cool for 10 minutes before serving.
