why make this recipe

There are many compelling reasons to make the Best Green Bean Casserole from Scratch. First, the taste is unmatched. Fresh ingredients enhance the flavor profiles and add a depth that pre-packaged versions simply can’t offer. When you taste this casserole, the richness of the creamy sauce combined with the crunch of French fried onions will sweep you off your feet.

Additionally, this dish is surprisingly easy to prepare. You can whip it up in under an hour, and the cooking techniques are straightforward, even for novice cooks. The ingredients are readily available at most grocery stores, making this recipe accessible for everyone.

The versatility of this dish is another plus. While it is traditionally served during Thanksgiving or Christmas, it makes a great accompaniment for any family gathering or casual dinner. It’s a comforting dish that pairs well with a range of main courses, from roast chicken to beef roast.

However, many home cooks find the thought of preparing a casserole daunting. Concerns about the dish being too watery or the texture being off can cause hesitance. This recipe addresses those pain points by providing clear instructions and techniques.

how to make Best Green Bean Casserole from Scratch

To create the Best Green Bean Casserole from Scratch, start by gathering all your ingredients. Proper measurement and preparation are key. Ensure that the green beans are either fresh or frozen and that you have all your other components at hand.

Begin by preheating your oven to 350°F (176°C). While the oven warms up, bring a large pot of salted water to a boil. Blanch the green beans for about 10 minutes. This step helps to maintain their vibrant color and crisp texture. Once done, drain the beans and set them aside.

In a large skillet, melt the butter over medium heat. Once melted, add the chopped onions and sliced mushrooms. Season with garlic powder, salt, and pepper. Sauté these for about five minutes, allowing the onions to become translucent and the mushrooms to soften.

Next, it’s crucial to create a creamy sauce. Sift in the flour one tablespoon at a time, stirring constantly to avoid lumps. Alternate adding this with 1/4 cup of the half-and-half and milk. Continue to mix until everything is combined and forms a thick sauce. A common mistake at this stage is adding all the flour at once; this will result in a pasty mixture.

Once your sauce is creamy, remove it from heat and add the drained green beans. Mix them in gently but thoroughly to ensure each bean is coated. Transfer this mixture into a greased 7″x3″x11″ baking dish.

Now, bake in the preheated oven for about 30 minutes. During the last five minutes, sprinkle the French fried onions on top and return the dish to the oven. This will give the casserole a perfect golden, crispy crust.

For best results, avoid overcooking the beans during blanching. They should be just tender, not mushy, to achieve that ideal texture.

Ingredients

  • 1 lb fresh or frozen green beans
  • 1/2 cup half-and-half
  • 1 1/2 cups whole milk
  • 1/3 cup flour
  • 3 tbsp butter
  • 1/2 medium onion (chopped)
  • 10 oz fresh sliced mushrooms (cleaned)
  • 1/2 tsp garlic powder
  • Salt and pepper to taste
  • 1 cup French’s Crispy Fried Onions

The ingredients play a crucial role in the final taste and texture of the casserole. Fresh green beans bring bright flavor and crunch, while the blend of half-and-half and whole milk provides a rich creaminess. The flour acts as a thickener for your sauce. If you need a substitute for half-and-half, you can mix equal parts of milk and heavy cream. For those who prefer a lighter option, low-fat milk works, though it may slightly alter the casserole’s richness.

Directions

First, preheat your oven to 350°F (176°C). Next, cook the green beans in boiling water for 10 minutes on high heat, then drain and set aside.

In a large skillet over medium heat, melt the butter. Add the chopped onions and sliced mushrooms along with the garlic powder, salt, and pepper. Cook this mixture for about five minutes until the onions are translucent and the mushrooms are tender.

Now it’s time to create your creamy sauce. Sift in flour one tablespoon at a time while continuously stirring to avoid lumps. Alternate this with the half-and-half and milk. Continue to stir until all of the flour and liquids are well combined. Avoid adding all the flour at once, as this will create a pasty sauce instead of a smooth one.

Once you achieve a chunky but creamy sauce, remove it from the heat. Gently fold in the drained green beans until well coated. Transfer this mixture into a greased 7″x3″x11″ baking dish.

Bake the casserole for about 30 minutes at 350°F. After that, sprinkle the French fried onions on top and return it to the oven for an additional five minutes. This gives the casserole a delightful crunch.

To ensure perfect results, keep an eye on the beans during cooking. They should maintain a slight bite to complement the creamy sauce and crispy topping.
