Fresh green bean casserole is a wonderful side dish for the holiday season.
- Fresh Green Beans: The star of the show! Fresh green beans are vibrant and crisp, providing a burst of garden-fresh flavor to your casserole. They bring a satisfying crunch and a burst of green color to the dish.
- Unsalted Butter: This luxurious ingredient adds a rich, creamy element to the casserole. It's used to sauté onions, garlic, and mushrooms, infusing the dish with a delightful buttery aroma.
- Onion: Finely chopped onions are a foundational element, contributing a sweet and savory note to the casserole. They melt into the creamy sauce, adding depth and a subtle hint of sweetness.
- Garlic: Minced garlic elevates the flavor profile with its aromatic, slightly pungent quality. It complements the earthiness of the mushrooms and provides a hint of warmth.
- White Mushrooms: Sliced white mushrooms bring the dish an umami-rich, earthy flavor. They release their moisture as they cook, enhancing the sauce's creaminess.
- Half and Half (or Half Milk and Half Heavy Cream): This creamy elixir adds a luxurious texture and subtle dairy richness to the sauce. It's the secret behind the velvety smoothness that blankets the green beans.
- Salt and Black Pepper: These seasonings are the flavor enhancers. They're your trusted companions in the kitchen, ensuring that every bite is perfectly seasoned to your liking.
- All-Purpose Flour: The unsung hero that thickens the sauce to the ideal consistency. It creates a silky texture that envelops the green beans.
- Chicken Broth or Vegetable Broth: The savory liquid gold that infuses depth of flavor into the sauce. Chicken broth adds a hearty note, while vegetable broth keeps it vegetarian-friendly.
- Panko Bread Crumbs: These light, airy bread crumbs bring a crispy and delicate crunch to the casserole. They're the textural contrast that makes each bite irresistible.
- French Fried Onions: These crispy, golden delights are the crowning glory of your casserole. They add a savory, slightly sweet onion flavor and a satisfying crunch, making the dish visually appealing and unforgettable.

How to Make Green Bean Casserole From Scratch
Preheat the Oven:
Preheat your oven to 400°F (204°C).
Prepare the Mushroom Sauce: In a large skillet, melt the butter over medium heat. Add the chopped onions and cook for about 3-4 minutes until they start to become translucent.
Adjust salt and pepper to taste.
Add the minced garlic and sliced mushrooms to the skillet. Cook for another 5-7 minutes until the mushrooms have released their moisture and are slightly browned. Season the mushroom mixture with salt and black pepper to taste.
Make the Creamy Sauce: Sprinkle the 3 tablespoons of flour over the mushroom mixture. Stir well to combine and cook for 2-3 minutes. Slowly pour in the half and half (or milk and cream mixture) while whisking constantly to prevent lumps. Cooking and stirring until the sauce thickens, about 5-7 minutes. Stir in the chicken or vegetable broth and simmer, stir a few times for another 5 minutes until the sauce is smooth and creamy.
Blanch the Green Beans: Bring a large pot of salted water to a boil. Add the fresh green beans and blanch for 2-3 minutes until they are bright green and slightly tender. Drain and immediately plunge them into a bowl of ice water to stop the cooking process. Drain again and set aside.
Combine the Sauce and Green Beans: Add the blanched green beans to the skillet with the mushroom sauce.
Gently stir to coat the green beans evenly with the sauce.
Assemble and Bake: Transfer the green bean and mushroom mixture to a greased 9x13-inch baking dish. Sprinkle the panko and fried onion topping evenly over the green beans.
Bake: Place the casserole in the oven for 20 minutes, or until the topping is golden brown and the casserole is bubbling.
Serve: Remove from the oven and let it cool slightly before serving. Enjoy your homemade green bean casserole!
Here are three variations of green bean casserole recipes:
1. Vegan Green Bean Casserole:
- Replace butter with vegan margarine or olive oil.
- Use almond milk or another non-dairy milk instead of half and half.
- Swap chicken broth for vegetable broth.
- For the topping, use vegan-friendly panko bread crumbs and crispy fried onions or make your own by frying thinly sliced onions in a mixture of flour and plant-based milk.
2. Bacon and Cheddar Green Bean Casserole:
- Add cooked and crumbled bacon to the mushroom sauce for a smoky flavor.
- Mix in shredded cheddar cheese into the mushroom sauce for a cheesy twist.
- Top the casserole with extra cheddar cheese and crumbled bacon along with the panko and fried onions before baking.
3. Mediterranean-Inspired Green Bean Casserole:
- Infuse Mediterranean flavors by adding sun-dried tomatoes, kalamata olives, and crumbled feta cheese to the mushroom sauce.
- Season the dish with oregano, thyme, and a pinch of crushed red pepper flakes for some extra zest.
- Instead of the traditional topping, mix crumbled feta cheese and breadcrumbs with olive oil and sprinkle it over the casserole before baking for a Mediterranean twist.
How to Store and Reheat
Storing Green Bean Casserole:
- Allow the casserole to cool to room temperature.
- Cover the casserole dish tightly with plastic wrap or aluminum foil, or transfer leftovers to an airtight container.
- Refrigerate within 2 hours of cooking.
- Store in the refrigerator for up to 3-4 days.
Reheating Green Bean Casserole:
- Preheat your oven to 350°F (175°C).
- If reheating the whole casserole, remove the plastic wrap or foil.
- If reheating individual servings, use an ovenproof dish.
- Bake the casserole, covered, for about 20-30 minutes or until heated through. You can uncover it for the last 10 minutes to crisp up the topping.
- If you prefer to reheat in the microwave, place individual servings on a microwave-safe plate, cover with a microwave-safe lid or microwave-safe plastic wrap with a small vent, and heat in 30-second intervals until hot.
Note: For the best texture and taste, reheating in the oven is recommended as it helps maintain the crispiness of the topping.
How to Make Ahead of Time
You can make green bean casserole ahead of time to save time on the day you plan to serve it. Here's how:
1. Prepare and Assemble the Casserole:
- Follow the recipe instructions until you assemble the casserole in a baking dish, but do not bake it.
2. Cover and Refrigerate:
- Once the casserole is assembled, cover it tightly with plastic wrap or aluminum foil to prevent air from getting in and refrigerate it. You can store it in the refrigerator for up to 24 hours before baking.
3. Bake When Ready:
- When you're ready to serve, preheat your oven to the specified temperature in the recipe (usually around 375°F or 190°C).
- Remove the plastic wrap or foil from the casserole dish.
- You may want to let the casserole sit at room temperature for about 20-30 minutes to take off the chill from the refrigerator.
- Bake the casserole in the preheated oven according to the recipe instructions. You may need to add a few extra minutes to the baking time since it's starting from a cold temperature. Keep an eye on it and bake until it's hot and bubbly, and the topping is golden brown.
- Once the casserole is heated through and the topping is crispy and brown, remove it from the oven, and let it cool slightly before serving.

Here are some top tips to help you make a delicious green bean casserole:
- Choose Fresh Green Beans: Opt for fresh green beans whenever possible as they have a better texture and flavor than canned or frozen ones.
- Trim and Blanch Green Beans: To ensure your green beans are tender and vibrant, trim the ends and blanch them briefly in boiling water before adding them to the casserole. Plunge them into ice water immediately to stop the cooking process and retain their color.
- Homemade Mushroom Sauce: Making the mushroom sauce from scratch with fresh mushrooms, onions, and garlic adds a depth of flavor that sets your casserole apart from canned soup-based versions.
- Season Well: Don't skimp on seasoning. Taste and adjust the salt and pepper levels in both the mushroom sauce and the overall casserole to your preference.
- Experiment with Toppings: While the classic topping includes panko bread crumbs and French fried onions, you can get creative with other options like crushed Ritz crackers, bacon bits, or even grated Parmesan cheese.
- Make-Ahead Convenience: You can assemble the casserole ahead of time and refrigerate it. Just be sure to let it come to room temperature before baking to ensure even cooking.
- Even Distribution: When combining the mushroom sauce with the green beans, make sure to coat the beans evenly for a consistent taste in every bite.
- Watch the Oven: Keep an eye on your casserole as it bakes to prevent over-browning of the topping. You may need to cover it with foil if it's getting too dark.
- Let It Rest: Allow the casserole to cool for a few minutes after removing it from the oven. This helps the sauce thicken and makes it easier to serve.
- Garnish and Serve: Before serving, consider garnishing with fresh herbs like chopped parsley or thyme to add a pop of color and freshness to your casserole.
Yes, you can use frozen green beans as a substitute for fresh ones in this recipe. Just be sure to thaw and drain them before using.
If baking the casserole directly from the refrigerator, you may need to add 5-10 minutes to the baking time to ensure it's heated through and the topping is crispy and golden brown.
You can use crispy fried shallots, crushed potato chips, or even homemade crispy onions as a substitute for French fried onions.
Fresh or frozen green beans are generally preferred over canned green beans for a better texture and flavor in green bean casserole. Canned green beans yield to a mushy casserole.
