Step‑by‑Step Instructions for Classic Southern Green Bean Casserole

Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This temperature is crucial for ensuring that your Classic Southern Green Bean Casserole bakes evenly, allowing the flavors to meld beautifully. While the oven warms up, you can prepare the green beans and other ingredients to save some time.

Step 2: Prepare the Green Beans
Trim the stem ends of 1 pound of fresh green beans and rinse them under cold water, then pat them dry with a clean kitchen towel. Properly preparation ensures tenderness and prevents excess water from diluting the casserole’s flavor. After drying, set them aside as you prepare the creamy sauce.

Step 3: Mix the Creamy Sauce
In a mixing bowl, combine one can of cream of mushroom soup, 1 cup of milk, 1 tablespoon of soy sauce, and freshly cracked black pepper to taste. Whisk these ingredients together until the mixture is smooth and creamy. This sauce serves as the flavor anchor for your Southern Green Bean Casserole, enhancing its richness.

Step 4: Coat the Green Beans
Add the trimmed green beans to the creamy mixture, and gently fold them in until they are completely coated. This step ensures every bite of green beans is enveloped in the luscious sauce, contributing to the warm, comforting flavors of your casserole. Take your time to fully incorporate the beans.

Step 5: Transfer to Baking Dish
Carefully transfer the green bean mixture into a 1.5 to 2-quart baking dish, spreading it out evenly with a spatula. This helps achieve consistent cooking and allows the casserole to heat through beautifully. It’s important to use a dish that can withstand the baking temperature for best results.

Step 6: Add the Crispy Onions
Sprinkle half of the French’s fried onions over the top of the casserole. These crispy onions add a delightful texture and flavor contrast to the creamy filling. Once sprinkled, you’re ready to let the oven work its magic on this comforting dish.

Step 7: Bake the Casserole
Place the casserole in the preheated oven and bake for 20-25 minutes. You’ll know it’s ready when it’s bubbly and heated throughout, with the aroma filling your kitchen, comforting your senses. Keep an eye on the timer, as you want to ensure it’s perfectly warm.

Step 8: Add Remaining Fried Onions
After the initial baking time, carefully remove the casserole from the oven and sprinkle the remaining fried onions on top. This second layer adds a satisfying crunch and beautiful golden color. It’s time to return the dish to the oven for an additional 5-10 minutes.

Step 9: Final Bake and Cool
Bake the casserole for another 5-10 minutes, or until the fried onions are golden brown and crispy. The slight browning will enhance the flavor and presentation of your Classic Southern Green Bean Casserole, making it irresistible to all.

Step 10: Serve and Enjoy
Once done, remove the casserole from the oven and let it rest for a few minutes before serving. This rest period allows the layers to settle, making it easier to serve. The rich, creamy texture combined with crispy fried onions makes this dish a cherished addition to any meal.
