Ingredients for ree drummond green bean casserole
Fresh green beans, creamy mushrooms, and that signature crispy onion topping—everything you need for Ree Drummond's iconic comfort dish.
| Ingredient | Amount | Notes |
|---|---|---|
| Fresh Green Beans 🥦 | 1 ½ lb | Trimmed, cut into 2-inch pieces |
| Yellow Onions 🧅 | 1 whole | Medium, finely chopped |
| Garlic Cloves 🧄 | 4 cloves | Minced, fresh preferred |
| Mushrooms 🍄 | 1 lb | White or cremini, sliced |
| All-Purpose Flour 🌾 | ⅓ cup | For roux, unsifted |
| Heavy Cream 🥛 | 1 cup | Full-fat for richness |
| Chicken Broth 💧 | 1 cup | Low-sodium preferred |
| French Fried Onions 🧅 | 1 cup | Store-bought or homemade |
| Salt 🧂 | 1 ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
| Butter 🧈 | ½ cup | Unsalted, cubed |
| Sugar 🍚 | 1 tbsp | For caramelizing onions |
| Milk 🥛 | ¼ cup | For thinning sauce |
| Dried Thyme 🌿 | ½ tsp | Or 1 tsp fresh thyme leaves |
| Worcestershire Sauce 🍶 | 1 tbsp | For umami depth |
The mushrooms and onions are where the magic happens. Cremini mushrooms add extra meatiness, but white work too. For onions, yellow or sweet onions caramelize best—skip the red unless you want color over flavor. I grab pre-sliced mushrooms from the store to save time, but chopping your own gives better texture. The French fried onions? Lawry's or Trader Joe's brands are my go-tos—they crisp up perfectly in the oven. Skip the pre-made sauce packets; homemade tastes like a restaurant.
No heavy cream? Half-and-half or evaporated milk works in a pinch, but the texture won't be as rich. Short on mushrooms? Extra onions and a splash of soy sauce add umami. The thyme can be fresh or dried—just halve the amount if using dried. Worcestershire sauce might be hard to find; soy sauce plus a pinch of sugar mimics it. For the green beans, haricots verts or asparagus work too, but they'll cook faster. Taste the sauce before adding milk—it should be thick enough to coat the back of a spoon, not gluey.
This casserole reheats beautifully—just cover with foil and bake at 350°F for 20 minutes. Leftovers keep for 4-5 days in the fridge, though it's rarely around that long. For make-ahead prep, assemble the dish (without baking) up to 24 hours ahead—cover and refrigerate. The onions stay crispy, and the sauce doesn't get watery. Freeze portions for up to 3 months—just bake straight from frozen, covered, for 50-60 minutes.
Why You'll Love This Recipe
- One-Pan Magic: I swear by this recipe when I’m too tired to wash pots. Sauté the onions, mushrooms, and garlic in one skillet, toss in the green beans, then dump it all into a baking dish—no extra pans, no stress. The flour-thickened sauce caramelizes right on top, and honestly? I’ve made it twice in the same day when my kids begged for seconds.
- Mushroom-Garlic Bomb: That earthy mushroom and garlic combo? It’s the secret weapon here. I’ll be real: I usually skip mushrooms in casseroles, but in this one, they melt into the creamy sauce and make every bite taste like a hug from a French chef. The onions add sweetness that balances the richness—it’s the kind of flavor that lingers.
- Leftovers That Don’t Suck: Between us, most casseroles turn into sad, dry bricks the next day. Not this one. The sauce stays creamy, the green beans hold their snap, and I’ve reheated portions for breakfast (yes, really) or packed it for lunch without judgment. It’s my go-to for meal prep because it doesn’t disappoint.
- Budget Stretch: Fresh green beans might sound fancy, but this recipe uses them efficiently—no wilting, no waste. The onions, garlic, and mushrooms bulk it up without breaking the bank, and flour stretches the sauce so it feels indulgent. I’ve made it for potlucks, family dinners, and even a last-minute dinner party, and no one’s ever questioned the price tag.
Step-by-step instructions for Ree Drummond's green bean casserole
This classic comfort dish comes together with rich layers of flavor and satisfying crunch—let's build it right.
🍳 Step 1: Sauté Onions and Mushrooms for Deep Flavor
In a large skillet, melt the 0.5 cup butter over medium heat. Add the 1 whole yellow onions and 1 tbsp sugar, cooking for 5-6 minutes until the onions soften and develop a golden caramelization. This step creates the sweet base that balances the savory elements.
Push the onions to one side of the pan and add the 1 lb mushrooms and 4 cloves minced garlic. Cook for 6-8 minutes until the mushrooms release their moisture and brown slightly. Stir occasionally to ensure even cooking—you want them tender but still holding their shape. Season with 1.5 tsp salt and 0.5 tsp black pepper, then remove from heat and set aside.
🍳 Step 2: Create a Creamy Sauce Base
In the same skillet (no need to clean it—the browned bits add flavor), reduce heat to medium-low and sprinkle in the 0.33 cup all-purpose flour, stirring constantly for 1-2 minutes to cook out the raw taste. Slowly whisk in the 1 cup heavy cream and 1 cup chicken broth, letting the mixture thicken gradually.
Add the 0.5 tsp dried thyme and 1 tbsp Worcestershire sauce, then simmer for 3-4 minutes until the sauce coats the back of a spoon. If it thickens too much, whisk in 1-2 tablespoons of milk to reach your desired consistency. This sauce will be the heart of your casserole, so taste and adjust seasoning now—it's easier to fix before baking.
🥘 Step 3: Combine Beans and Sauce
In a large mixing bowl, combine the 1.5 lb trimmed green beans (cut into 2-inch pieces) with the onion-mushroom mixture and the creamy sauce. Gently toss everything together until the beans are evenly coated. The sauce should cling to the beans but still allow them to stay distinct—this ensures each bite has both creamy and fresh elements.
Transfer the mixture to a 9x13-inch baking dish, spreading it evenly. Here's the thing—don't press down on the beans. You want them to stay slightly separated so they cook through properly and maintain their texture. This is where many home cooks go wrong by overpacking the dish.
🔥 Step 4: Bake Until Bubbly and Golden
Preheat your oven to 350°F. Sprinkle the 1 cup French fried onions evenly over the top of the casserole, pressing down gently so they stick. This creates that iconic crunchy topping that makes the dish irresistible.
Bake uncovered for 35-40 minutes until the top is golden brown and the edges bubble slightly. The casserole is done when the beans are tender but still hold their shape—you should be able to pierce them easily with a fork. If the top browns too quickly, tent loosely with foil for the last 10 minutes to prevent burning.
⏰ Step 5: Rest and Serve for Perfect Texture
Remove the casserole from the oven and let it rest for 10-15 minutes before serving. This resting period allows the juices to redistribute, ensuring each bite is creamy and flavorful rather than watery. The French fried onions will be perfectly crispy on top, providing that satisfying crunch with every spoonful.
Serve warm with crusty bread or as a side dish to complement roasted meats. The combination of sweet caramelized onions, earthy mushrooms, creamy sauce, and crispy topping makes this casserole a true comfort food classic that's perfect for family gatherings or cozy weeknight dinners.
Pro Tips For Making Ree Drummond Green Bean Casserole
- Trim Green Beans Properly: Cut off the ends at a sharp angle—this prevents them from curling up in the oven and makes them look like they came from a fancy restaurant. I used to just chop them straight across, and they’d always twist into little question marks.
- Sauté Mushrooms Until Dry: Cook the mushrooms until all the liquid evaporates—this stops the casserole from turning soggy later. I learned this the hard way after making a batch where the mushrooms just sat in their own juice, making the whole dish watery.
- Skip the Pre-Cooked Beans: Use fresh green beans straight from the pod—blanching them for 3 minutes first keeps their bright color and crisp texture. I was lazy once and used canned beans, and the dish tasted dull and mushy.
- Make the Roux Smooth: Whisk the flour and butter mixture until it’s completely smooth before adding milk—this prevents lumps in the creamy sauce. I’ve had to fish out chunks before, and it’s not a fun dinner party moment.
Best sauces and condiments for ree drummond green bean casserole
Creamy Mushroom Sauce
The star of this casserole is the velvety mushroom sauce, where the magic happens. I start by sautéing onions and garlic in butter until golden—this caramelization adds natural sweetness that balances the earthy mushrooms.
The key is using a roux made with ⅓ cup all-purpose flour cooked until golden brown before adding 1 cup heavy cream and 1 cup chicken broth. This creates a rich, thick base that coats the green beans perfectly.
For extra depth, I always add 1 tbsp Worcestershire sauce—it brings that umami punch that makes the sauce taste restaurant-quality. 🍄
French Fried Onions
The crispy topping is non-negotiable in Ree Drummond's version. I recommend using Lawry's French fried onions or Trader Joe's—they're pre-cooked and just need baking to get that perfect crunch. For a homemade version, thinly slice onions, fry them in oil until golden, and drain on paper towels.
Sprinkle them over the casserole right before baking so they stay crispy. The secret is pressing them down lightly so they stick and create a golden crust on top. 🧅
Buttery Herb Garnish
After baking, I like to finish the casserole with a drizzle of melted butter mixed with 1 tsp fresh thyme leaves and a pinch of black pepper. This adds a bright, herby note that cuts through the richness of the sauce.
For extra flair, I sometimes sprinkle with toasted breadcrumbs mixed with 1 tbsp grated Parmesan cheese—it adds another layer of texture. This step is optional but elevates the dish to next-level comfort food. 🌿
Cheesy Twist Option
Want to make it even heartier? Stir ½ cup shredded sharp cheddar cheese into the sauce before baking, or sprinkle it over the top with the onions. The cheese melts into the creamy sauce, creating pockets of gooey goodness.
I recommend Monterey Jack for a milder flavor or Gruyère for a nutty depth. This variation is perfect for picky eaters or when you want extra indulgence. 🧀
Spicy Kick Variation
For those who love heat, add ½ tsp smoked paprika and ¼ tsp cayenne pepper to the sauce for a subtle smoky spice. Or, stir in 2 tbsp hot sauce (like Frank's RedHot) after baking.
The heat contrasts beautifully with the creamy sauce and crispy onions. This version is a crowd-pleaser at spicy food gatherings. 🌶️
Make-Ahead Sauce
Prep the sauce ahead of time to save cooking day stress. Make it up to 2 days in advance and store it in an airtight container in the fridge. Reheat gently on the stovetop with a splash of milk to restore creaminess.
I also like to pre-chop all the vegetables and store them separately—this cuts active cooking time in half. Just assemble and bake when ready. ⏰

Frequently asked questions
Can I use canned green beans instead of fresh?
Drain and rinse 2 (15-ounce) cans of green beans (cut or whole) and skip the trimming step. For best texture, pat them dry thoroughly with a towel before mixing with the sauce. Canned beans work especially well when making this ahead of time.
How do I make the French fried onions extra crispy?
Start by preheating your oven to 375°F before baking the casserole. Press the onions down firmly with a spatula to ensure full contact with the sauce. For even more crunch, broil for 1-2 minutes at the very end, watching closely to avoid burning.
What can I substitute if I don't have Worcestershire sauce?
Mix 1 tbsp soy sauce with ½ tsp sugar for a similar umami depth. Alternatively, use 1 tsp fish sauce or ½ tsp liquid smoke for a smoky twist. The sauce will still taste rich and flavorful without it.
Can I make this casserole ahead and freeze it?
Yes! Assemble the casserole completely (including the onion topping) and refrigerate for up to 24 hours before baking. For freezing, bake as directed, then let cool completely. Store in an airtight container for up to 3 months. To reheat, bake at 350°F for 30-40 minutes, covered with foil, until heated through.
Why did my casserole turn out watery?
This usually happens when the sauce isn't thickened enough before baking or the beans release too much moisture. To fix it, make sure your roux is fully cooked (golden brown) before adding liquids, and simmer the sauce until it coats the back of a spoon. Also, avoid overpacking the beans in the baking dish—leave room for them to cook evenly.
