Ingredients for Green Bean Casserole
To make this dish truly outstanding, we recommend using fresh ingredients whenever possible. Here’s what you’ll need:
For the Casserole
- 500g fresh green beans, trimmed and halved (or 450g frozen green beans, thawed)
- 1 tablespoon olive oil
- 1 small onion, finely diced
- 2 cloves garlic, minced
- 1 cup button mushrooms, sliced
- 3 tablespoons butter
- 3 tablespoons plain flour
- 2 cups whole milk (or cream for a richer dish)
- 1/2 cup chicken stock (or vegetable stock for a vegetarian version)
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1/4 teaspoon ground nutmeg (optional, for a subtle depth of flavour)
- 1 cup grated cheddar cheese (optional, for extra creaminess)
For the Topping
- 1 cup crispy fried onions (store-bought or homemade)
- 1/2 cup panko breadcrumbs
- 2 tablespoons grated Parmesan cheese (optional)
- 1 tablespoon melted butter
How to Make Green Bean Casserole
Step 1: Prepare the Green Beans
- Begin by preheating your oven to 190°C (375°F). Grease a medium-sized baking dish and set it aside.
- If using fresh green beans, blanch them in boiling salted water for 2-3 minutes until they are bright green and slightly tender. Drain and immediately plunge the beans into ice water to halt the cooking process. This step ensures they maintain their vibrant colour and crisp texture.
- If using frozen green beans, ensure they are thawed and drained thoroughly.
Step 2: Sauté the Aromatics
- Heat olive oil in a large frying pan over medium heat. Add the diced onion and cook until softened, about 3-4 minutes.
- Stir in the minced garlic and sliced mushrooms, cooking until the mushrooms release their moisture and begin to brown. This adds a robust umami flavour to the dish.
Step 3: Create the Creamy Sauce
- In the same pan, melt butter and sprinkle the flour evenly over the sautéed mixture. Stir continuously for 1-2 minutes to cook out the raw flour taste.
- Gradually whisk in the milk and chicken stock, ensuring a smooth, lump-free sauce. Continue stirring as the sauce thickens, about 5 minutes.
- Season with salt, pepper, and a pinch of nutmeg for added warmth. If desired, stir in the grated cheddar cheese for an extra layer of creaminess.
Step 4: Assemble the Casserole
- Gently fold the prepared green beans into the creamy sauce, ensuring they are well coated. Transfer the mixture to the greased baking dish and spread it evenly.
Step 5: Prepare the Crunchy Topping
- In a small bowl, combine crispy fried onions, panko breadcrumbs, and Parmesan cheese (if using). Drizzle with melted butter and mix until evenly coated.
- Sprinkle the topping mixture generously over the green bean casserole.
Step 6: Bake the Casserole
- Place the casserole in the preheated oven and bake for 20-25 minutes or until the topping is golden brown and the sauce is bubbling around the edges.
- Allow the casserole to cool for a few minutes before serving to let the flavours meld.
Serving Suggestions
This Green Bean Casserole pairs beautifully with a variety of main dishes. Serve it alongside roast chicken, grilled salmon, or a festive Christmas roast. It’s also a fantastic accompaniment to other sides like mashed potatoes or buttered rolls.
Variations and Tips
- Make It Vegetarian: Use vegetable stock in place of chicken stock for a completely vegetarian casserole.
- Add Protein: Incorporate cooked shredded chicken or crispy bacon bits for a heartier dish.
- Experiment with Toppings: Swap the crispy onions for crushed cornflakes, toasted almonds, or a mix of cheeses for a unique twist.
- Dairy-Free Option: Use almond or soy milk and a dairy-free butter substitute for a lactose-free version.
