Ingredients for emeril green bean casserole
Fresh green beans, crispy fried onions, and velvety cream of mushroom soup—this is Emeril's iconic holiday casserole.
| Ingredient | Amount | Notes |
|---|---|---|
| Fresh Green Beans 🌱 | 1 ½ lb | Trimmed, cut into 2-inch pieces |
| Yellow Onions 🧅 | 2 whole | Thinly sliced for frying |
| Cream of Mushroom Soup 🍄 | 2 cups | Canned, unsalted variety preferred |
| Heavy Cream 🥛 | ½ cup | Full-fat for creamy texture |
| Shredded Cheddar Cheese 🧀 | 1 ½ cups | Medium or sharp variety |
| Butter 🧈 | ½ cup | Unsalted, melted for frying |
| All-Purpose Flour 🌾 | ¼ cup | For coating fried onions |
| Salt 🧂 | 1 ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Garlic Powder 🧄 | ½ tsp | For seasoning onions |
| Fresh Parsley 🌿 | 0.1 cup | Chopped, for garnish |
| Milk 🥛 | ¼ cup | Whole milk for creaminess |
The green beans should be bright green and crisp—avoid anything rubbery or yellowing. Fresh green beans from the farmers market have the best texture, but pre-cut beans from the grocery store freezer section work in a pinch. For the onions, yellow onions are ideal, but white or red will do. Thinly slice them yourself—pre-sliced onions won't fry as crispy. Costco or Trader Joe's often have the best prices for bulk onions, and Diamond Crystal kosher salt is my go-to for seasoning. The cream of mushroom soup is non-negotiable—Campbell's or Betty Crocker are the most reliable brands for that classic flavor, but homemade mushroom sauce elevates it further if you're feeling ambitious.
No fresh green beans? Pre-cooked green beans from a can or frozen section work perfectly—just drain and pat them dry. Short on onions? Swap in shallots for a sweeter flavor, but increase the amount by 20% since they're smaller. No heavy cream? Half-and-half or evaporated milk will work, though the texture won't be as rich. Cheese substitute? Gruyère or Swiss add a delightful depth, but sharp cheddar is the most accessible option. For the fried onions, panko breadcrumbs can replace flour for extra crunch, and a splash of apple cider vinegar in the frying butter keeps them golden without burning. Emeril's trick? Fry the onions in two batches to avoid overcrowding—they need space to crisp up properly.
This casserole tastes even better the next day, so make it ahead if you're hosting. Assemble the bean mixture, cover, and refrigerate for up to 24 hours before baking. The fried onions stay crispy for about 30 minutes after frying, so fry them fresh right before baking. Store leftovers in an airtight container for up to 5 days in the fridge, or freeze for 3 months. Reheating? Cover with foil and warm at 350°F for 15 minutes—the onions might soften slightly, but the flavor stays intact. Garnish with fresh parsley right before serving for a pop of color.

Step-by-step instructions for Emeril's green bean casserole
Master Emeril's signature technique for the perfect balance of creamy filling and crispy onion topping.
Prepare the Green Beans
Trim the ends off the 1.5 lb fresh green beans and cut them into 2-inch pieces. Spread them evenly on a large rimmed baking sheet. Drizzle with 1 tablespoon of water and toss gently to coat. This light misting helps prevent burning during the initial baking phase.
Preheat your oven to 400°F. Arrange the green beans in a single layer on the baking sheet, leaving space between each piece. Bake for 10-12 minutes until they begin to soften slightly but remain crisp with a bright green color. You want them to blanch just enough to release their natural sweetness without turning mushy.
Create the Creamy Filling
While the green beans bake, melt the 0.5 cup butter in a large skillet over medium heat. Add the 2 whole yellow onions that have been thinly sliced and cook for 8-10 minutes until they begin to soften and turn translucent. Remove the onions from the skillet and set them aside.
In the same skillet, reduce heat to medium-low and whisk in the 0.25 cup all-purpose flour to create a roux. Cook for 1-2 minutes until the flour is fully incorporated and smells nutty. Slowly pour in the 2 cups cream of mushroom soup and the 0.5 cup heavy cream while whisking continuously to prevent lumps. Stir in the 0.25 cup milk and bring the mixture to a gentle simmer for 3-4 minutes until it thickens slightly.
Season and Combine Ingredients
Remove the skillet from heat and stir in the 1.5 tsp salt, 0.5 tsp black pepper, and 0.5 tsp garlic powder. Add the 1.5 cups shredded cheddar cheese and stir until completely melted and smooth. The mixture should be creamy with a velvety texture—if it's too thick, whisk in 1-2 tablespoons of hot water to reach your desired consistency.
Transfer the green beans from the baking sheet to a large mixing bowl. Pour the creamy cheese mixture over the green beans and toss gently to coat each piece evenly. The beans should be fully enveloped in the sauce, with no dry spots remaining. This step ensures every bite delivers that perfect combination of creamy and crispy textures.
Prepare the Crunchy Onion Topping
Return the reserved fried onions to the skillet over medium heat. Sprinkle with an additional pinch of salt and 0.25 tsp black pepper to enhance their flavor. Cook for 2-3 minutes until they become crispy and golden brown, stirring occasionally. The onions should have a satisfying crunch when you press them between your fingers.
Transfer the green bean mixture to a greased 9x13-inch baking dish and spread it out evenly. Sprinkle the crispy fried onions evenly over the top, pressing down gently to help them adhere. The onions should cover the entire surface without overlapping too much—this creates that signature crunchy layer that sets Emeril's casserole apart.
Bake to Golden Perfection
Bake the casserole at 375°F for 20-25 minutes until the top is golden brown and the edges are bubbling. You'll notice the cheese begins to brown and develop a delicious, toasty aroma. The filling should be heated through but still retain its creamy texture.
Remove from the oven and let it rest for 5 minutes to allow the layers to set slightly. Garnish with the 0.1 cup chopped fresh parsley just before serving. The parsley adds a fresh contrast to the rich, creamy flavors and makes the dish look as appealing as it tastes. Serve warm for the ultimate comfort food experience.
Pro Tips For Making Emeril Green Bean Casserole
- Blanch Beans First: Toss your green beans in boiling water for 3-4 minutes before assembling the casserole—this keeps them bright green and prevents that sad, limp texture after baking. I learned this the hard way when my first batch turned into a mushy green sludge by the time it hit the oven.
- Sauté Onions Low and Slow: Caramelize those onions in a dry pan over medium-low heat for 10-12 minutes until deep golden, not browned. Rushed onions taste raw, and this step actually changes the outcome—trust me, your casserole’s flavor will thank you.
- Mix Cream and Cheese Cold: Whisk the heavy cream and cheddar together before adding the soup, and keep it chilled until the last minute. Warm cream curdles like a nightmare, and you’ll end up with a gluey mess instead of a creamy sauce. Sounds weird, but it works.
- Top with Crumbs Early: Sprinkle the buttery breadcrumb topping right after mixing the filling, then bake as directed. This guarantees a crispy crust instead of soggy bread—no last-minute topping hacks needed. (Yes, even if you’re impatient like me.)
Creative variations of these flavors
Emeril's Spicy Kick
Add 1 teaspoon cayenne pepper or 2 tablespoons hot sauce like Crystal or Tabasco to the creamy filling for Emeril's signature heat. For a smoky twist, swap ½ teaspoon smoked paprika for regular garlic powder in the seasoning.
I love adding a pinch of cayenne to the fried onions before topping for an extra kick. 🌶️
Cheesy Variations
Swap out cheddar for Gruyère or Swiss cheese for a nutty depth, or mix in ½ cup cream cheese for extra creaminess. For a Southern twist, add ½ cup shredded sharp cheddar and ½ cup crumbled blue cheese to the filling.
The blue cheese adds a tangy punch that balances the richness beautifully.
Vegetarian Protein Boost
Add 1 cup cooked white beans or chickpeas to the bean mixture for extra protein and texture. I also recommend stirring in ½ cup sautéed mushrooms for an umami boost. This makes the dish heartier and more satisfying, especially for vegetarian guests.
Gluten-Free Adaptation
For a gluten-free version, replace the all-purpose flour with ½ cup gluten-free flour blend and ensure your cream of mushroom soup is certified gluten-free. Use gluten-free breadcrumbs if substituting panko for the onion coating. The texture stays crispy while keeping the dish safe for gluten-sensitive diners.
Make-Ahead Shortcut
Prepare the creamy bean mixture up to 24 hours ahead and refrigerate in an airtight container. Just before baking, assemble the casserole and bake as directed.
For the fried onions, fry them fresh right before adding to the top to maintain maximum crunch. This shortcut saves time without sacrificing flavor. ⏰
Holiday Twist
Add ½ cup diced ham or bacon to the bean mixture for a festive holiday version. For a vegetarian option, use crispy roasted butternut squash instead. Garnish with fresh rosemary sprigs for a fragrant, aromatic touch that elevates the dish for special occasions.

Frequently asked questions
Why does Emeril's green bean casserole need to bake the beans first?
Baking the beans first removes excess moisture and intensifies their natural sweetness. This prevents a watery casserole and ensures the creamy sauce clings perfectly to each piece. The 10-12 minute pre-bake at 400°F also helps soften them slightly while keeping their vibrant green color.
Can I make this casserole without fried onions?
For a shortcut, use 1 cup crushed potato chips (like potato or corn) or ½ cup panko breadcrumbs mixed with 1 tablespoon melted butter as a crunchy topping. For extra flavor, add ½ teaspoon garlic powder to the crumbs. The texture won't be identical, but it still delivers satisfying crunch.
How do I keep the fried onions extra crispy?
Fry the onions in two batches in 350°F oil to avoid overcrowding. Drain them on a wire rack (not paper towels) to prevent steam from making them soggy. For maximum crunch, add them to the casserole just before the final 20-minute bake instead of frying them days ahead.
What's the best way to reheat leftovers?
Cover with foil and warm at 350°F for 15-20 minutes until heated through. The onions may soften slightly, but the flavor stays rich. For crispier onions, sprinkle extra fried onions on top just before serving. Store leftovers in an airtight container for up to 5 days in the fridge.
Can I use frozen green beans instead of fresh?
Yes! Use 2 cups frozen green beans (thawed and drained) and skip the initial baking step. Frozen beans are already blanched, so they'll absorb the creamy sauce perfectly. For best results, pat them completely dry before mixing with the cheese sauce. This prevents a watery texture.
