French’s Green Bean Casserole
Equipment
- oven
- casserole dish
- mixing bowl
- whisk
- spatula
- measuring cups
- measuring spoons
Ingredients
- 2 cans condensed cream of mushroom soup 10.75 ounces each
- 1/2 cup whole milk
- 1 tsp soy sauce
- 1/4 tsp ground black pepper
- 4 cans cut green beans 14.5 ounces each, thoroughly drained
- 1 can French’s Original Crispy Fried Onions 6 ounces
Instructions
- Preheat your oven to 350°F. Lightly grease a 1.5-quart casserole dish or a 9×13-inch baking dish.
- In a large mixing bowl, combine the condensed cream of mushroom soup, whole milk, soy sauce, and ground black pepper. Stir thoroughly with a whisk or spoon until the mixture is smooth and evenly combined.
- Add the thoroughly drained cut green beans to the soup mixture. Gently fold them in with a spatula until all the green beans are evenly coated in the creamy sauce.
- Reserve 1 cup of the French’s Original Crispy Fried Onions for the topping. Stir the remaining crispy fried onions into the green bean mixture until they are well distributed.
- Pour the entire green bean mixture into the prepared casserole dish, spreading it evenly with the back of a spoon or spatula to ensure an even layer.
- Bake in the preheated oven for 25 to 30 minutes, or until the casserole is hot and bubbly around the edges. The sauce should appear slightly thickened.
- Carefully remove the casserole from the oven. Evenly sprinkle the reserved 1 cup of French’s Original Crispy Fried Onions over the top of the hot casserole.
- Return the casserole to the oven and bake for an additional 5 minutes, or until the crispy fried onions on top are golden brown and perfectly crisp. Serve hot.
Notes
Simple Ways to Customize Your Casserole
- Add Some Cheese: Stir in a cup of shredded cheddar cheese for an extra rich and cheesy version.
- Fresh Bean Upgrade: For a brighter flavor, use fresh blanched green beans instead of canned.
- Extra Crunch: Mix in some crispy bacon bits with the fried onions for a smoky, savory crunch.
My Pro Tips for Casserole Perfection
- Thorough Draining: Take the time to drain the green beans well to prevent a soupy consistency.
- Even Coating: Gently fold the beans into the sauce to ensure every piece is evenly coated.
- Hot and Bubbly: Bake until the edges are actively bubbling for the best texture, like you would for a great corn casserole.
- Final Crisp: The last five minutes of baking are crucial for achieving a perfectly golden brown topping.
How to Store and Reheat Your Leftovers
- Store: Place any leftover casserole in an airtight container and refrigerate for up to 4 days.
- Freeze: You can freeze the baked casserole for up to 3 months, tightly wrapped, though the onions will soften.
- Reheat: Reheat portions in a 350°F oven for 15-20 minutes until heated through for the best texture.
- Make-Ahead Tip: Assemble the casserole a day ahead, cover, and refrigerate; add 5-10 minutes to the baking time.
Frequently Asked Questions
Can I use fresh green beans instead of canned?
Yes, you can absolutely use fresh green beans. Simply blanch about 1.5 pounds of trimmed beans in boiling water for 5 minutes until tender-crisp, then drain and proceed with the recipe. This gives a lovely fresh flavor and firmer texture.
What can I substitute for cream of mushroom soup?
For a homemade version, sauté 8 ounces of sliced mushrooms with a little onion, then make a simple white sauce with butter, flour, and milk. You could also use cream of celery or golden mushroom soup for a different flavor profile.
How do I keep the fried onions from getting soggy?
The key is adding the final cup of onions just for the last 5 minutes of baking. This gives them just enough time to get golden and crispy without absorbing too much moisture from the casserole below.
Can I make this green bean casserole ahead of time?
Absolutely. Assemble the casserole completely but wait to add the final onion topping. Cover and refrigerate for up to 24 hours, then bake as directed, adding a few extra minutes to the initial bake time since it will be cold.
