Step-by-Step Cooking Instructions

How to Cook Classic Green Bean Casserole: A Step-by-Step Guide
Follow these detailed instructions to ensure your casserole comes out perfectly every time.
1. Preheat the Oven:
Start by preheating your oven to 350°F (175°C). This ensures your casserole bakes evenly.
2. Prepare the Green Beans:
- Fresh Green Beans: If using fresh green beans, blanch them first by boiling them for 5 minutes, then transferring them immediately into ice water to stop the cooking process. Drain and set aside.
- Canned or Frozen Green Beans: If you’re using canned beans, simply drain them. If using frozen green beans, thaw them before using.
3. Mix the Casserole Base:
In a large mixing bowl, combine the cream of mushroom soup, milk, soy sauce, and black pepper. Stir until the mixture is smooth and well blended.
4. Combine the Green Beans:
Gently fold the prepared green beans into the soup mixture, ensuring they’re fully coated with the creamy sauce.
5. Add Half the Fried Onions:
Add half of the crispy fried onions into the green bean and soup mixture. This will give the casserole some crunch in every bite.
6. Transfer to a Baking Dish:
Pour the green bean mixture into a 9x13-inch baking dish and spread it evenly.
7. Bake the Casserole:
Place the casserole in the preheated oven and bake for 25-30 minutes, or until the casserole is bubbly around the edges.
8. Top with Remaining Onions:
After baking, remove the casserole from the oven and sprinkle the remaining crispy fried onions evenly on top.
9. Final Bake:
Return the casserole to the oven for an additional 5-10 minutes, or until the onions are golden brown and crispy.
10. Serve Hot:
Once fully baked, remove the casserole from the oven and allow it to cool for a few minutes before serving.
Common Mistakes to Avoid
To make sure your Classic Green Bean Casserole turns out perfect, avoid these common mistakes:
- Overcooking the Green Beans: Fresh green beans should only be blanched briefly; overcooking them before baking can result in mushy beans.
- Not Draining Canned or Frozen Beans: Excess liquid from canned or frozen beans can make the casserole watery, so be sure to drain them well.
- Skipping the Stirring Step: Stirring the crispy onions into the casserole helps distribute the crunch throughout the dish. Don’t skip this step!
- Forgetting to Preheat the Oven: Starting with a cold oven can lead to uneven cooking.
- Burning the Fried Onions: Keep an eye on the casserole during the final few minutes to ensure the fried onions don’t burn.
