Introduction

Green bean casserole is a classic dish that is often seen on Thanksgiving tables and holiday spreads. It’s a comforting and delicious side dish that pairs well with roasted turkey, mashed potatoes, and all the other fixings. While the traditional green bean casserole made with canned green beans and cream of mushroom soup is a popular choice, there is a way to take this classic dish to the next level and make it even more delicious – by making it from scratch with a homemade cream of mushroom soup and a cup of milk. Last year, my goal was to make the entire Thanksgiving menu from scratch, including this homemade green bean casserole recipe. It was a challenging but rewarding experience that elevated the dish to a whole new level, making it a perfect addition to any holiday feast, whether it’s for Easter, Thanksgiving, or Christmas.

By using fresh green beans, homemade cream of mushroom soup, and crispy fried onions, you can create an authentic green bean casserole that will wow your family and friends. The flavors and textures of the homemade ingredients elevate this dish and make it a standout on any table. So why settle for the canned version when you can make a truly exceptional green bean casserole from scratch with homemade soup instead of canned soup? This recipe calls for a 1 1/2-quart baking dish, so make sure to have one on hand before you begin. You can also try substituting other condensed soups, such as celery or cream of chicken, for the cream of mushroom soup for a different flavor. For an added kick, try adding 1/4 teaspoon of garlic or celery powder or ground pepper for additional seasoning.

In this blog, we will take you through the process of making an authentic green bean casserole step by step. From choosing the right ingredients to preparing the green beans and crafting the creamy mushroom sauce, we will guide you through the entire process to ensure that you create the best green bean casserole you’ve ever tasted. So let’s get started and make this classic dish shine!

Choosing the Right Ingredients for Authenticity

When it comes to making an authentic green bean casserole, the choice of ingredients is key. By using fresh and high-quality ingredients, you can ensure that your casserole will have the best flavor and texture possible.

For the green beans, fresh is always the best option. Look for bright green beans that are firm and free from blemishes. These will give your casserole a crisp and tender texture that canned or frozen beans just can’t match.

As for the mushroom soup, making your own from scratch is the way to go. This allows you to control the flavor and thickness of the soup, resulting in a more authentic and delicious casserole. Use fresh mushrooms and a combination of butter, all-purpose flour, chicken broth, and heavy cream to create a rich and creamy sauce that will coat the green beans perfectly. For an extra boost of garlic flavor, add both fresh garlic and garlic powder to the sauce.

Fresh vs. Canned Green Beans: Which to Use?

One of the first choices you’ll have to make when making an authentic green bean casserole is whether to use fresh or canned green beans. While both options can work, there are some differences to consider.

Fresh green beans are the top choice for a truly authentic and flavorful casserole. They have a crisp and tender texture that canned or frozen beans just can’t match. Look for bright green beans that are firm and free from blemishes when selecting your fresh beans.

If fresh green beans are not available or you’re short on time, frozen green beans can be a good alternative. They are already blanched and ready to use, which saves you the step of blanching fresh beans. Just be sure to thaw and drain them before using in the casserole.

Canned green beans are the least desirable option for an authentic green bean casserole. They can be mushy and lack the fresh taste and texture of fresh or frozen beans. However, if you do choose to use canned beans, be sure to drain them well before adding them to the casserole.

Essential Ingredients for the Perfect Casserole

To make an authentic green bean casserole, there are a few essential ingredients that you’ll need. These ingredients are what give the casserole its signature flavor and texture. Here are the key ingredients:

  • Green beans: Fresh green beans are the star of the show. Look for bright green beans that are firm and free from blemishes.
  • Cream of mushroom soup: Homemade cream of mushroom soup is the best choice for an authentic casserole. It’s creamy, flavorful, and adds a delicious richness to the dish.
  • Crispy fried onions: The crispy fried onions on top of the casserole give it a delightful crunch and add a burst of flavor. You can make your own or use store-bought crispy fried onions.
  • Black pepper: A little black pepper adds a touch of heat and enhances the flavors in the casserole.

Preparing Your Green Beans

Now that you have chosen the right ingredients for your authentic green bean casserole, it’s time to prepare the green beans. The goal is to have tender yet crisp green beans that are perfectly cooked and ready to be coated in the creamy mushroom sauce.

Start by trimming the ends of the green beans and cutting them into bite-sized pieces. This will ensure that the green beans cook evenly and are easy to eat.

Next, blanch the green beans in boiling water for a few minutes until they are tender yet still retain their bright green color. Immediately transfer the blanched green beans to an ice bath to stop the cooking process and preserve their crispness.

Once the green beans have cooled, drain them well and pat them dry. They are now ready to be added to the casserole and coated in the creamy mushroom sauce.

Tips for Trimming and Cleaning Green Beans

When it comes to preparing green beans for your authentic green bean casserole, there are a few tips and tricks to keep in mind. These will help ensure that your green beans are trimmed and cleaned properly, resulting in the best flavor and texture.

  • Start by trimming the ends of the green beans. This can be done by simply snapping off the stem end of each bean or by using a sharp knife to cut off the ends.
  • After trimming, give the green beans a good rinse under cold water to remove any dirt or debris. This is especially important if you’re using fresh beans that still have some dirt on them.
  • Once the green beans are clean, pat them dry with a clean kitchen towel or paper towels. This will help remove any excess moisture and make sure the beans cook evenly.
  • For added flavor, you can toss the trimmed and cleaned green beans with a drizzle of olive oil before blanching them. This will give them a light coating of oil and enhance their natural flavor.

Blanching Green Beans: A Step-by-Step Guide

Blanching green beans is an essential step in preparing them for your authentic green bean casserole. It helps to preserve their bright green color and crisp texture while slightly softening them for the casserole. Here is a step-by-step guide on how to blanch green beans:

  1. Fill a large pot with water and bring it to a rolling boil.
  2. While the water is heating up, prepare an ice bath in a large bowl or sink by filling it with cold water and ice cubes.
  3. Once the water is boiling, add the trimmed and cleaned green beans to the pot. Make sure the water covers the beans completely.
  4. Cook the green beans for 2-3 minutes, or until they are tender yet still crisp. Keep a close eye on them to avoid overcooking.
  5. Using a slotted spoon or tongs, transfer the blanched green beans to the ice bath. Let them sit in the ice bath for a few minutes to cool down and stop the cooking process.
  6. Once the green beans are cool, drain them well and pat them dry with a clean kitchen towel or paper towels. They are now ready to be added to the casserole.

The Secret to a Crispy Onion Topping

The crispy onion topping is what sets an authentic green bean casserole apart from the rest. It adds a delightful crunch and burst of flavor to the dish. While you can certainly use store-bought french fried onions, making your own crispy fried onions is surprisingly easy and well worth the effort. To make your own, simply sauté 1 cup onions in a pan until they are golden brown and crispy. Sprinkle them on top of the casserole before baking for an extra delicious touch.

To make your own crispy fried onions, start by thinly slicing a sweet onion. Sauté the onion slices in a bit of unsalted butter over medium-high heat until they are golden, caramelized, and soft. Set them aside to cool before combining them with the breadcrumb mixture. The result is a homemade crispy onion topping that is irresistible and adds an extra layer of deliciousness to your green bean casserole.

Choosing Onions for Your Casserole

When making an authentic green bean casserole, the choice of onions for the crispy onion topping is important. You want to choose an onion that will caramelize well and add a sweet and savory flavor to the dish.

One of the best onions to use for the topping is a sweet onion, such as a Vidalia or Walla Walla onion. These onions have a mild and sweet flavor that pairs perfectly with the green beans and creamy mushroom sauce.

To make the crispy onion topping, thinly slice the onions and sauté them in a bit of unsalted butter over medium-high heat until they are golden, caramelized, and soft. This will give the onions a rich and savory flavor that will complement the other ingredients in the casserole.

A general rule of thumb is to use about 1 cup of sliced onions for the topping. You can adjust the amount based on your personal preference and the size of your baking dish.

How to Fry Onions to Perfection

Frying onions to perfection for the crispy onion topping is surprisingly easy and adds a delicious and crunchy element to your authentic green bean casserole. Here is how to fry onions to perfection:

  1. Start by thinly slicing a sweet onion, such as a Vidalia or Walla Walla onion.
  2. Heat a generous amount of cooking oil, such as vegetable or canola oil, in a deep skillet or pot over medium heat.
  3. Once the oil is hot, add the sliced onions to the pot. Make sure the onions are submerged in the oil and not overcrowded.
  4. Fry the onions, stirring occasionally, until they are golden brown and crispy. This will take about 10-15 minutes.
  5. Using a slotted spoon or tongs, transfer the fried onions to a paper towel-lined plate to drain off any excess oil.
  6. Let the fried onions cool completely before using them as a topping for your green bean casserole.

The result is a batch of homemade crispy fried onions that will take your green bean casserole to the next level with their delicious flavor and satisfying crunch.

Crafting the Creamy Mushroom Sauce

The creamy mushroom sauce is the heart of an authentic green bean casserole. It coats the green beans and adds a rich and savory flavor to the dish. Making your own creamy mushroom sauce from scratch is surprisingly easy and well worth the effort.

To make the sauce, start by sautéing white button mushrooms and garlic in butter until the mushrooms release their moisture and become tender. Stir in flour to create a roux, and then add chicken broth and heavy cream. Simmer the sauce until it thickens and reduces to the perfect consistency.

The result is a homemade creamy mushroom sauce that is packed with flavor and pairs perfectly with the green beans in your casserole.

Homemade vs. Store-Bought: What’s Best for Your Casserole?

When it comes to the creamy mushroom soup for your authentic green bean casserole, you have the choice of making it from scratch or using a can of cream of mushroom soup. Both options can work, but there are some differences to consider.

Making your own mushroom soup from scratch allows you to control the flavor and ingredients, resulting in a more authentic and delicious casserole. It’s also a great way to use fresh mushrooms and create a customized sauce that suits your taste.

On the other hand, using a can of cream of mushroom soup is a convenient option that saves you time and effort. It provides a creamy and flavorful base for your casserole with minimal preparation.

Ultimately, the choice between homemade and store-bought mushroom soup comes down to personal preference and the amount of time and effort you’re willing to invest in your casserole. Both options can yield a delicious and satisfying result.

Step-by-Step Instructions for a Rich Mushroom Sauce

Creating a rich and flavorful mushroom sauce for your authentic green bean casserole is easier than you might think. Here is a step-by-step guide on how to make a delicious mushroom sauce from scratch:

  1. Start by melting butter in a skillet over medium heat. Add sliced mushrooms and cook until they release their moisture and become tender.
  2. Stir in flour and cook for a minute or two, until the flour is well incorporated and slightly golden.
  3. Gradually whisk in chicken broth, making sure to scrape up any browned bits from the bottom of the skillet.
  4. Bring the mixture to a simmer and cook until the sauce has thickened, stirring occasionally.
  5. Stir in heavy cream and continue cooking until the sauce is smooth and creamy.
  6. Season the sauce with salt and pepper to taste.

The result is a rich and flavorful mushroom sauce that will add a deliciously creamy element to your green bean casserole.

Assembling Your Green Bean Casserole

Now that you have prepared all the components of your authentic green bean casserole, it’s time to assemble it and get it ready for baking. Here is how to assemble your green bean casserole:

  1. Preheat your oven to the specified temperature in the recipe.

  3. Sprinkle cheddar cheese and parmesan cheese over the green bean mixture, adding a flavorful and melty element to the casserole.
  4. Top the casserole with the crispy fried onions, ensuring that they are spread evenly across the top.
  5. Place the assembled casserole in the preheated oven and bake according to the specified baking time in the recipe.

Layering Ingredients for Maximum Flavor

Layering the ingredients in your authentic green bean casserole is essential for maximum flavor and a beautiful presentation. Here’s how to layer the ingredients:

  2. Sprinkle a layer of cheddar cheese over the green beans. This adds a rich and melty element to the casserole.
  3. Add a layer of parmesan cheese on top of the cheddar cheese. This adds a savory and tangy flavor to the casserole.
  4. Repeat the layers if desired, depending on the size of your baking dish and the amount of ingredients you have.

By layering the ingredients, you create a delicious and visually appealing casserole that will impress your family and friends.

Baking Times and Temperatures for the Perfect Crust

If you’re looking to add a little extra crunch to your authentic green bean casserole, there are several innovative toppings you can try. Here are a few ideas to get you started:
