How to Make Homemade Green Bean Casserole
Saut Onions: In a large skillet, heat 4 tablespoons of butter over medium-high heat. Add the chopped onions and cook until they re tender and beautifully caramelized, about 7-8 minutes. Stir often to avoid burning. Then, add the mushrooms and cook for an additional 4 minutes. Finally, stir in the garlic and cook for just 1 minute before transferring the mixture to a bowl.
Make the Sauce: In the same skillet, reduce the heat to medium and add the remaining 4 tablespoons of butter. Sprinkle in the flour or cornstarch and whisk quickly to combine. Cook this mixture for about 2 minutes while whisking often. Slowly stir in the half-n-half, along with salt and pepper. Cook this creamy concoction for 4-5 minutes until it thickens slightly. Give it a taste to check the seasonings.
Prepare Green Beans: Preheat your oven to 350 °F. In a large pot, bring water to a boil. Add the fresh green beans and cook for about 6-7 minutes until they re bright green yet still crisp. Drain them and consider transferring them to an ice bath to cool quickly, though this step is optional.
Combine and Bake: Now, mix the onion-mushroom mix into the creamy sauce, stirring well to combine. Add the green beans to this rich mixture, coating them evenly. If you re using Parmesan cheese, sprinkle it over the top. Pour the entire mix into a 9 x 9 baking dish and bake for 25 minutes or until it s bubbly and golden. Finally, remove it from the oven and scatter the fried onions on top, baking for an additional 5 minutes. Serve it immediately for the best experience!
Optional: Garnish with fresh herbs like parsley for a lovely touch.
