How to Make Creamy Green Bean Casserole
-
Preheat the oven to 450°F (232°C). Prepare a large baking sheet by lining it with parchment paper or a silicone baking mat. This will prevent sticking and make clean-up a breeze!
-
Prepare the onion. Thinly slice it and separate the slices. In three separate bowls, set up your breading station: one with flour, another with panko mixed with salt and pepper, and the last with whipped egg and milk. Dip each onion slice in flour first, then the egg mixture, and finally, coat with panko. Place the coated slices on the baking sheet. Bake for about 20 minutes, flipping twice until they are golden brown. Set aside.
-
Lower the oven temperature to 400°F (204°C). This ensures your casserole bakes perfectly without overcooking.
-
Boil a gallon of water with 1 Tablespoon of salt in a large saucepan. Once boiling, add the fresh green beans and cook for 5 minutes. Transfer them to a bowl of ice water to stop the cooking process, then drain and set aside for later.
-
Melt butter in a large ovenproof skillet over medium-high heat. Add the sliced mushrooms, along with 1 teaspoon of salt and pepper. Cook until mushrooms release their moisture, which takes about 5 minutes. Then, add minced garlic and sauté for another 2 minutes. Sprinkle the remaining flour on top and stir until combined. Pour in the chicken broth and let it simmer for 3 minutes. Lower the heat to medium-low, then mix in half-and-half, cooking until thick, about 10 minutes or until desired consistency is reached.
-
Combine the baked onions and the prepared green beans into the skillet. If your skillet isn’t oven-safe, transfer the mixture to a greased 2–3-quart casserole dish. Top with the remaining baked onions and bake until bubbling, about 15 minutes. Once done, remove from the oven and serve warm.
Optional: For extra flavor, drizzle with a little lemon juice before serving.
