📝 Preparation Steps
1
Preheat your oven to 400 degrees F. Line a large baking sheet with parchment paper and spray with nonstick cooking spray.

Bring a large pot of salted water to a rolling boil. Cook trimmed green beans in two batches for ⏱️ 2-3 minutes each, until tender-crisp. Transfer blanched beans to a large bowl.
