Green Bean Casserole
I never thought I'd see the day when Green Bean Casserole would become a staple at our table, but here we are. Last Sunday, after a long stroll through the farmer's market, I realized that all I wanted was something warm and comforting that reminded me of home. Alex, who’s hit another growth spurt, devoured his portion and even asked if we could have it again soon. If you're in search of a quick dish that brings a smile (and some sneaky veggies) to your family's faces, this is it.

Ingredients
- 2 pounds fresh green beans
- 2 tablespoons unsalted butter
- 1 medium yellow onion
- 3 cloves garlic
- 8 ounces button or cremini mushrooms
- ¼ cup all-purpose flour
- 2 cups half & half
- 1 cup chicken or vegetable broth
- 1 teaspoon soy sauce
- ½ teaspoon salt
- ½ teaspoon black pepper
- ¼ teaspoon ground nutmeg
- 1½ cups crispy fried onions
Step-by-step instructions
- Preheat your oven to 375°F (190°C).
- Bring a large pot of salted water to a boil. Add the green beans and cook for 2-3 minutes until bright green and slightly tender. Immediately transfer them to a bowl of ice water to stop the cooking. Drain and set aside.
- In a large skillet, melt the butter over medium heat. Add the onion and cook for 3-4 minutes until softened. Stir in the garlic and mushrooms, cooking for 5-7 minutes until the mushrooms release their moisture and start to brown.
- Sprinkle the flour over the mushroom mixture and stir to coat evenly. Cook for 1-2 minutes to remove the raw flour taste.
- Gradually whisk in the broth and half & half, stirring constantly to avoid lumps. Add the soy sauce, salt, pepper, and nutmeg. Simmer for about 5 minutes, stirring often, until the sauce thickens.
- In a 9×13-inch casserole dish, add the blanched green beans, the mushroom sauce, and ½ cup of the crispy fried onions. Mix everything together until the green beans are evenly coated. Spread the mixture into an even layer.
- Sprinkle the remaining crispy fried onions evenly over the top.
- Bake for 20-25 minutes, or until the sauce is bubbling and the onions on top are golden brown. Let it cool for a few minutes before serving.

Recipe tips & variations
Here's a tip I discovered: adding a bit more soy sauce can kick up the umami element, which even the kids appreciate. Feeling adventurous? Try adding some cooked bacon bits or a dash of hot sauce for an extra zing.
Storage & reheating
Store any leftovers in an airtight container in the fridge for up to 3 days. For reheating, pop it back into the oven at 350°F until warmed through, about 10-15 minutes.

FAQs
How do you keep Green Bean Casserole from becoming watery?
To keep the casserole from getting watery, be sure to thoroughly drain your green beans after boiling. Also, letting the sauce simmer till it thickens is key.
Can I make Green Bean Casserole ahead of time and bake it later?
Absolutely! You can prep this casserole up to the point of baking, cover it well, and store it in the fridge. Just add the fried onions right before baking for freshness.
Is it better to use fresh, frozen, or canned green beans for Green Bean Casserole?
Fresh is my go-to because they hold their texture well, but frozen works too. Canned are okay in a pinch, just be sure to rinse them well.
Why are my fried onions getting soggy on top of the casserole?
To keep them crispy, add the fried onions toward the end of the baking process, just for the last 5 minutes or so.
