How to Make Delicious French Onion Green Bean Casserole Recipe You’ll Love
Step 1: Prepare the Sauce
Start by mixing together the Campbell’s® Condensed Cream of Mushroom Soup, milk, and black pepper. This creamy base is essential as it binds all the flavors together and gives the casserole its rich texture. Stir until smooth, ensuring everything is well combined.
Step 2: Combine Ingredients
In a large bowl, combine your green beans with the soup mixture. Gently fold them together so each bean gets coated in that delicious sauce. This step ensures every bite is bursting with flavor!
Step 3: Add Fried Onions
Next, stir in about two-thirds of the French’s® Original Crispy Fried Onions. These crispy morsels will add that beloved crunch we all crave in casseroles. Save the remaining onions for topping later; they’ll get nice and crispy while baking!
Step 4: Bake
Transfer your mixture into a greased baking dish and spread it out evenly. Bake in a preheated oven at 350°F (175°C) for about 25 minutes until it’s bubbly. This allows all those flavors to meld perfectly while giving your casserole that golden finish.
Step 5: Add Topping and Finish Baking
After 25 minutes, take it out of the oven and sprinkle on those reserved crispy fried onions. Return it to bake for an additional 10 minutes. This final touch adds an irresistible crunch that everyone will love!
And there you have it! Your Delicious French Onion Green Bean Casserole Recipe You’ll Love is ready to be served. Enjoy every creamy, crunchy bite!
