Step‑by‑Step Instructions for Homemade Green Bean Casserole
Step 1: Fry Shallots
Begin by slicing the shallots thinly and heating a skillet over medium heat. Add a few tablespoons of oil and fry the shallots for about 5-7 minutes, stirring occasionally, until they turn golden brown and crispy. Once done, remove them from the skillet and set aside on a paper towel to drain any excess oil, bringing a delightful crunch to your green bean casserole.
Step 2: Blanch Green Beans
Bring a large pot of water to a boil and add a generous pinch of salt. Carefully insert the fresh green beans and boil for 3-4 minutes, or until they are vibrant green and tender-crisp. Immediately transfer the beans to an ice bath to halt the cooking process, ensuring they retain their beautiful color and crunch, which will enhance your homemade green bean casserole.
Step 3: Make the Creamy Mushroom Sauce
In the same skillet, add a drizzle of oil if needed and sauté minced garlic for about 1 minute until fragrant. Stir in sliced mushrooms and cook for 5-6 minutes until softened and golden. Sprinkle flour over the mushrooms, stirring constantly to create a roux, then gradually pour in vegetable broth or coconut milk, whisking until the sauce thickens and turns creamy—this will be the heart of your homemade green bean casserole.
Step 4: Assemble Casserole
In a large mixing bowl, combine the blanched green beans with the creamy mushroom sauce. Stir gently to ensure the beans are well-coated with the sauce. Transfer this delightful mixture into a greased baking dish, spreading it evenly to prepare for the topping of your homemade green bean casserole.
Step 5: Top with Parmesan and Fried Shallots
Sprinkle your preferred shredded parmesan cheese evenly over the green bean mixture, allowing it to melt beautifully during baking. Next, add the crispy fried shallots on top, creating a crunchy layer that will contrast perfectly with the creamy sauce beneath. This topping is essential for that classic feel in your homemade green bean casserole.
Step 6: Bake
Preheat your oven to 375°F (190°C). Bake the assembled green bean casserole for 20-30 minutes, or until the top is golden brown and bubbly. Keep an eye on it towards the end to prevent burning. This baking process melds all the flavors together beautifully, transforming it into a cozy dish that’s sure to impress!

Green Bean Casserole Recipe FAQs
How do I select fresh green beans?
When choosing fresh green beans, look for bright green beans that are firm and crisp. Avoid any with dark spots or wilting, as these indicate age or poor quality. The more vibrant, the better your green bean casserole will taste!
What’s the best way to store leftover green bean casserole?
Store any leftover casserole in an airtight container in the fridge for up to 3 days. Ensure it’s cooled completely before sealing it to maintain freshness. If you want to keep it longer, you can freeze it for up to 2 months!
Can I freeze my green bean casserole? How?
Absolutely! If you want to freeze your homemade green bean casserole, assemble it without baking, then cover it tightly with foil or plastic wrap to prevent freezer burn. To thaw, place it in the refrigerator overnight before baking at 375°F to heat thoroughly.
What if my sauce is too thick or too thin?
If your creamy mushroom sauce is too thick, simply whisk in a bit more broth or plant-based milk until you reach your desired consistency. Conversely, if it’s too thin, continue cooking it over medium heat to allow it to reduce and thicken, stirring often to prevent burning.
Are there any dietary considerations for pets or allergies?
Definitely! While this green bean casserole is a hit for humans, it shouldn’t be shared with pets, especially due to the garlic and onions. Additionally, be cautious of any allergies among your guests—always check for common allergens such as gluten in the flour or dairy in the cheese.
How do I ensure my fried shallots stay crispy?
To keep your fried shallots nice and crispy, make sure to drain them on paper towels immediately after frying. Also, consider adding them just before serving, as exposing them to moisture can cause them to lose their crunch over time.
