Let’s dive into how to make the best green bean casserole ever!
Ingredients
The secret to a truly outstanding green bean casserole lies in the quality and balance of the ingredients. Let’s break down each component and explore some potential substitutions.
- Green Beans: 1 pound fresh green beans, trimmed and cut into 1-inch pieces (or two 14.5-ounce cans of cut green beans, drained). Fresh green beans offer the best flavor and texture. Canned beans are a convenient alternative, but be sure to drain them thoroughly. Frozen green beans can also be used; thaw and drain well before using. The cellular structure of green beans is largely water, and overcooking can lead to a mushy texture.
- Cream of Mushroom Soup: 2 (10.75-ounce) cans condensed cream of mushroom soup. This forms the base of the creamy sauce. If you’re looking for a healthier option, you can make your own cream of mushroom soup from scratch using fresh mushrooms, vegetable broth, and a touch of cream or milk.
- Milk: ½ cup milk. Adds moisture and helps to thin the soup. Whole milk provides the richest flavor, but 2% or skim milk can also be used. For a dairy-free alternative, try unsweetened almond milk or soy milk.
- Soy Sauce: 1 tablespoon soy sauce. Adds a depth of umami flavor that enhances the overall taste. Tamari can be used as a gluten-free substitute.
- Black Pepper: ¼ teaspoon black pepper. Seasoning is key! Freshly ground black pepper provides the best flavor.
- Onion Powder: ½ teaspoon onion powder. Adds a subtle onion flavor without the need to chop onions.
- Crispy Fried Onions: 1 (6-ounce) can crispy fried onions. These provide the signature crispy topping. Reserve half for topping and use half in the casserole mixture. French’s brand is the most well-known, but store brands work just as well.
- Butter: 2 tablespoons unsalted butter, melted. Added to the crispy fried onions to enhance flavor and ensure even browning
Expert Tips
Here are some of my personal tips and tricks for making the best green bean casserole, based on years of experience and experimentation:
- Don’t overcook the green beans: Whether you’re using fresh, canned, or frozen green beans, it’s crucial not to overcook them. Overcooked beans will become mushy and detract from the overall texture of the casserole. If using fresh beans, blanch them briefly in boiling water for 3-4 minutes, then immediately transfer them to an ice bath to stop the cooking process.
- Toast the crispy fried onions: Before adding the crispy fried onions to the casserole mixture, toast them lightly in a dry skillet over medium heat for a few minutes. This will enhance their flavor and crispness.
- Add a touch of garlic: For an extra layer of flavor, sauté a clove of minced garlic in butter before adding it to the casserole mixture.
- Experiment with different toppings: While crispy fried onions are the classic topping, feel free to experiment with other options. Some delicious alternatives include crushed Ritz crackers, toasted breadcrumbs, or grated Parmesan cheese.
- Make it ahead of time: Green bean casserole can be assembled ahead of time and baked just before serving. Simply prepare the casserole as directed, cover it tightly with plastic wrap, and refrigerate it for up to 24 hours. When ready to bake, remove the plastic wrap and bake as directed, adding a few extra minutes to the baking time if necessary.
FAQ
Can I use fresh mushrooms instead of cream of mushroom soup?
Yes, you can definitely use fresh mushrooms! Sauté sliced mushrooms with some garlic and butter until tender, then mix them with a homemade cream sauce made from broth, milk, and flour. This will give your casserole a richer, more earthy flavor.
Can I make this casserole dairy-free?
Absolutely! Use dairy-free cream of mushroom soup (many brands offer this now), and substitute unsweetened almond milk or soy milk for the milk. You can also use dairy-free crispy fried onions or make your own using gluten-free flour and dairy-free milk.
Can I freeze green bean casserole?
While you can freeze green bean casserole, the texture may change slightly. It’s best to freeze it before baking. Wrap it tightly in plastic wrap and then in foil. Thaw it overnight in the refrigerator before baking as directed. Be aware that the topping may lose some of its crispness.
How do I prevent the crispy fried onions from burning?
To prevent burning, add the crispy fried onions during the last 15 minutes of baking. This allows them to get golden brown and crispy without becoming overly dark. You can also tent the casserole with foil if the onions are browning too quickly.
What can I use if I don’t have soy sauce?
If you don’t have soy sauce, you can use Worcestershire sauce or tamari as a substitute. These will provide a similar savory flavor. If you don’t have either of those, a pinch of salt will help to enhance the flavor of the other ingredients.
Can I add cheese to green bean casserole?
Yes! Adding cheese is a great way to customize your green bean casserole. Shredded cheddar, Gruyere, or Parmesan cheese would all be delicious additions. Sprinkle the cheese on top of the casserole during the last 10 minutes of baking, or stir it into the casserole mixture before baking.
So there you have it – the Best Green Bean Casserole recipe that’s guaranteed to be a hit at your next holiday gathering.
