Step-by-Step Preparation of Creamy Green Bean Casserole
Creating the ultimate creamy green bean casserole from scratch is not only satisfying but a great culinary adventure. Here’s a detailed breakdown of the steps to guide you through this delicious classic.
Preheat and Prepare Your Baking Sheet
Start by preheating your oven to 450°F (232°C). This initial high temperature is crucial for achieving crispy baked onions later. While the oven heats up, take a large baking sheet and line it with parchment paper or a silicone baking mat. This not only makes cleanup a breeze but also ensures the onions don’t stick while they bake.
Making the Baked “Fried” Onions
Now comes the fun part—preparing those heavenly baked onions! Thinly slice your medium onion and separate the slices. Set up a breading station with three bowls:
- Flour: ½ cup of all-purpose flour in one bowl.
- Panko Mixture: Combine ¾ cup of panko breadcrumbs, ½ teaspoon of salt, and ¼ teaspoon of ground black pepper in another.
- Egg Wash: In a third bowl, whisk together one large egg and 1 tablespoon of milk.
Using one hand for dry ingredients and the other for wet, dip the onion slices first in flour, then in the egg wash, and finally coat them with the panko mixture. Lay them out evenly on the prepared baking sheet. Bake for about 20 minutes, flipping them twice until they’re golden brown and crisply delicious.
Blanching the Green Beans
Once your onions are sizzling in the oven, it’s time to prepare the green beans. Fill a large saucepan with a gallon of water and 1 tablespoon of salt and bring it to a boil. Add the 1 pound of fresh green beans and let them boil for just 5 minutes. This quick blanching helps maintain their color and crunch. Prepare an ice water bath in a large bowl, then transfer the blanched beans straight from the pot into the icy water. Drain and set aside.
Cooking the Mushroom Sauce
In a large ovenproof skillet, melt 2 tablespoons of unsalted butter over medium-high heat. Add 8 ounces of sliced mushrooms, a teaspoon of salt, and your black pepper. Stir occasionally for about 5 minutes until the mushrooms begin releasing their moisture. Next, add 2 cloves of minced garlic and cook for another 2 minutes. Incorporate 2 tablespoons of flour, mixing until combined, then pour in ¾ cup of chicken or vegetable broth. Let it simmer for 3 minutes. Reduce heat and stir in 1 and ¼ cups of half-and-half, cooking until the sauce thickens, which should take about 10 minutes.
Combining and Baking the Casserole
Remove your skillet from the heat and fold in about a quarter of your baked onions along with the blanched green beans. Stir well to combine everything perfectly. If you aren’t using an oven-safe skillet, transfer this mixture into a greased 2–3-quart casserole dish. Top with the remaining onions and bake at 400°F (204°C) until golden and bubbly around the edges—about 15 minutes.
Voilà! Your creamy green bean casserole is ready to wow your friends and family. Enjoy it warm, knowing you’ve made something truly special from scratch!
