Step-by-Step Instructions to Make This Green Bean Casserole Recipe
1. Preheat the Oven
- Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking dish.
2. Prepare the Green Beans
- If using fresh green beans, boil them in salted water for 5–7 minutes until tender-crisp. Drain and transfer to an ice bath to stop the cooking process. For frozen green beans, thaw and drain them thoroughly.
3. Make the Sauce
- In a large mixing bowl, combine the cream of mushroom soup, milk, soy sauce, garlic powder, salt, and pepper. Stir until smooth.
4. Assemble the Casserole
- Add the green beans to the sauce mixture and toss until evenly coated. Pour the mixture into the prepared baking dish.
- Sprinkle 1 cup of crispy fried onions over the top.
5. Bake
- Bake the casserole uncovered for 25 minutes. Remove from the oven, sprinkle additional fried onions on top, and bake for another 5–10 minutes until the onions are golden and crispy.
6. Rest and Serve
- Allow the casserole to rest for 5 minutes before serving. Serve warm and enjoy!
Common Mistakes to Avoid
- Overcooking Green Beans: Boil fresh green beans just until tender-crisp to retain their texture and color.
- Watery Sauce: Drain frozen or fresh green beans thoroughly to prevent a watery casserole.
- Burning the Onions: Add the extra fried onions toward the end of baking to avoid burning.
- Under seasoning: Taste and adjust the seasoning before baking for a perfectly balanced dish.
Serving and Presentation Tips
- Pair with Main Dishes: Serve alongside roasted turkey, glazed ham, or baked chicken for a complete meal.
- Family-Style: Present the casserole in a decorative baking dish for a warm, inviting touch.
- Individual Servings: Plate portions with a garnish of parsley or slivered almonds for added elegance.
Expert Tips
- Make It Ahead: Assemble the casserole (excluding the fried onion topping) and refrigerate for up to 24 hours. Add the onions just before baking.
- Reheat Leftovers: Warm in the oven at 350°F (175°C) until heated through. Avoid microwaving to keep the crispy topping intact.
- Freeze for Later: Prepare and freeze the casserole without the onions. Thaw overnight, bake, and add the onions for the final few minutes of cooking.
