how long to bake green beans at 400

The baking time for green beans at 400°F (200°C) can vary depending on the desired level of doneness and the specific preparation method. Here are some general guidelines:

1. Simple Green Beans: Toss green beans with olive oil, salt, and pepper. Bake at 400°F (200°C) for:

   • 12-15 minutes for tender but still crisp green beans.
   • 18-20 minutes for softer, more tender green beans.

2. Roasted Green Beans: Toss green beans with olive oil, salt, pepper, and any desired aromatics (e.g., garlic, lemon zest). Bake at 400°F (200°C) for:

   • 15-20 minutes for tender and slightly caramelized green beans.
   • 25-30 minutes for more deeply roasted and tender green beans.

3. Green Beans with Additional Ingredients: If you’re adding ingredients like cheese, breadcrumbs, or nuts, you may need to adjust the baking time. A good rule of thumb is to add 2-5 minutes to the baking time to account for the extra ingredients.

Remember to check on the green beans halfway through the baking time and shake the pan to ensure even cooking. You can also use a fork to test for tenderness. If the green beans are still too crunchy, continue baking in 2-3 minute increments until they reach your desired level of doneness.
