How to Make Best-Ever Green Bean Casserole
Follow these simple steps to prepare this delicious Best-Ever Green Bean Casserole:
Step 1: Prepare the Onions
Preheat your oven to 475°F (245°C). In a large mixing bowl, combine the thinly sliced onions with flour, panko, and salt. Coat a sheet pan with nonstick cooking spray and evenly spread the onion mixture across the pan.
Step 2: Bake the Onions
Bake the onions on the middle rack for about 30 minutes until they are golden brown, tossing them 2 to 3 times during cooking to ensure even browning. Once done, set them aside and lower the oven temperature to 400°F (200°C).
Step 3: Blanch the Green Beans
In an 8-quart saucepan, bring a gallon of water and 2 tablespoons of the kosher salt to a boil. Add the rinsed, trimmed, and halved green beans, and blanch them for 5 minutes. Drain the beans in a colander and plunge them into a bowl of ice water to stop the cooking process. Drain again and set aside.
Step 4: Sauté the Mushrooms
In a 12-inch cast iron skillet (or any large skillet), melt the butter over medium-high heat. Add the mushrooms, 1 teaspoon of salt, and pepper. Cook, stirring occasionally until the mushrooms start to release their moisture, about 4 to 5 minutes.
Step 5: Create the Sauce
Add the minced garlic and freshly ground nutmeg and continue cooking for another 1 to 2 minutes. Sprinkle the mixture with flour and stir to combine, allowing it to cook for just a minute. Gradually pour in the chicken broth, stirring until well combined, and simmer for 1 minute. Decrease the heat to medium-low and add the half-and-half, stirring continuously until the mixture thickens, approximately 6 to 8 minutes.
Step 6: Assemble the Casserole
Remove the skillet from the heat and fold in 1/4 of the crispy onions and the blanched green beans. Mix everything well, then top it with the remaining onions. Transfer the skillet into your 400°F oven and bake until bubbly, which will take about 15 minutes.
Serve this warm masterpiece straight from the oven, delighting in the crispy topping and creamy filling of the Best-Ever Green Bean Casserole. You may want to warn loved ones on how delicious it is, or prepare to guard the dish fiercely—because seconds are inevitable!
