Preparing Green Bean Casserole
Creating a delicious green bean casserole from scratch can be a delightful experience. It’s all about layering flavors and textures, and with a few simple steps, you’ll have a dish that’s both impressive and comforting. Let’s dive into the preparation process.
Sauté the onions
Start by heating 2 tablespoons of olive oil in a large skillet over medium-high heat. Once the oil is hot, toss in a sliced medium onion and sprinkle with a bit of Kosher salt and freshly ground black pepper. Stir occasionally with a wooden spoon until the onions soften and turn a nice golden brown—this usually takes about 10 to 12 minutes. The caramelization process is vital, as it develops that sweet flavor profile we all love in a classic green bean casserole. Remember, patience here pays off!
Cook the mushrooms
Next, reduce the heat to medium and add 1 pound of quartered mushrooms to the skillet. Season again with salt and pepper to really bring out their umami essence. Stir occasionally as the mushrooms shrink, soften, and take on a beautiful brown color. This step typically takes another 10 to 12 minutes. A great tip here is to let the mushrooms really brown; it will enhance the overall depth of flavor in your casserole.
Add the green beans
Now it’s time for the star of the show: the green beans! Add 1 pound of trimmed and chopped green beans to your skillet. While it might look a bit crowded, don’t worry; the greens will shrink as they cook. Season with salt and pepper, and keep stirring. Cook for about 8 to 10 minutes until the beans are bright green and tender. The fresh green of the beans alongside the beautifully caramelized onions and mushrooms makes for a stunning visual—a true holiday dish!
Create the gravy
Once all your veggies are perfectly cooked, add 2 tablespoons of unsalted butter to the pan and let it melt in. Sprinkle 2 tablespoons of flour over the mixture and stir for a couple of minutes to incorporate it into the fat and the browned bits in the skillet. Gradually pour in 1¾ cups of whole milk, mixing it slowly to avoid lumps, and let it thicken. Add 2 tablespoons of soy sauce or tamari and a clove of finely grated garlic for that extra kick. Make sure to season again with salt and pepper to taste.
Bake to perfection
Now that everything is combined, preheat your oven to 425°F (220°C). Top the mixture generously with French’s Onions from the container. This classic topping brings that beloved crunch to your green bean casserole. Bake for about 20 to 25 minutes until bubbly and golden brown. Your kitchen will smell amazing, and the anticipation will keep everyone asking, “When’s dinner?”

Cooking Tips for Green Bean Casserole
Skillet vs. Baking Dish
When preparing your green bean casserole, the choice between a skillet and a baking dish can impact your dish's final texture. A skillet allows for easier browning of the onions and mushrooms, giving them a wonderful depth of flavor. However, if your skillet feels overcrowded, don't hesitate to transfer everything into a baking dish for even cooking. This way, you'll achieve that beautifully golden top without sacrificing the creamy goodness underneath.
Prepping Ahead of Time
Want to make your life easier? You can prep your green bean casserole a day in advance without the onion topping. Just refrigerate it, then add the crispy onions before baking. This not only saves time but also allows the flavors to meld together beautifully overnight. A little advance planning goes a long way in ensuring your dish is a hit at the dinner table!
