Ingredients for betty crocker green bean casserole
Six ingredients for the classic layers—crispy, creamy, and nostalgic in every bite.
| Ingredient | Amount | Notes |
|---|---|---|
| Fresh Green Beans 🍃 | 2 lbs | Trimmed, cut into 2-inch pieces |
| Cream of Mushroom Soup 🍄 | 2 cans | 10.5 oz each, condensed (Betty Crocker preferred) |
| French-Fried Onions 🧅 | 1 bag | 16 oz, crushed or whole (Betty Crocker brand) |
| Milk 🥛 | ½ cup | Whole milk for creaminess |
| Butter 🧈 | ½ cup | Unsalted, melted |
| All-Purpose Flour 🌾 | ¼ cup | For thickening |
| Salt 🧂 | ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ¼ tsp | Freshly ground preferred |
| Garlic Powder 🧄 | ½ tsp | For extra flavor |
| Milk 🥛 | ¼ cup | For topping mix |
| Parmesan Cheese 🧀 | ¼ cup | Grated, for extra richness |
| Heavy Cream 🥛 | ¼ cup | For extra creaminess (optional) |
The Betty Crocker cans are non-negotiable here—nothing else gives that exact creamy, mushroomy flavor. Grab the condensed version (not the ready-to-serve) for the right consistency. For the onions, Betty Crocker brand is iconic, but French's works too. Fresh green beans? Trader Joe's or the produce section at Walmart usually have the best deals. The key is trimmed and cut evenly—no one wants a mouthful of tough ends. Pro tip: Parboil the beans for 3 minutes before assembling to soften them just a bit.
No Betty Crocker soup? Homemade mushroom soup (blend cooked mushrooms, milk, and a splash of cream) works, but it's a whole other process. Heavy cream can replace milk in the soup layer if you want extra richness. The French-fried onions can be swapped for crushed potato chips in a pinch (trust me, it works). For the topping mix, Parmesan adds depth—skip it if you're watching sodium. The garlic powder is optional but takes this from 'good' to 'holiday dinner' in one step. If you're prepping ahead, make the topping mix first—it keeps for weeks in an airtight container.
This casserole tastes even better the next day—the flavors meld and the onions get extra crispy. Bake it in advance for holiday dinners and reheat at 350°F for 20 minutes. Portion into individual dishes before baking if you're serving a crowd—no one wants to fight over the last slice. Leftovers? Freeze for up to 3 months—just thaw overnight in the fridge before reheating. The French-fried onions on top? Sprinkle them fresh after baking so they stay crunchy and golden—worth the extra minute.

Step-by-step instructions for Betty Crocker's green bean casserole
This classic comfort dish delivers that perfect combination of crispy golden onions and creamy mushroom sauce every time.
Blanch and Prepare the Green Beans
Start by trimming the ends off the 2 lbs of fresh green beans and cutting them into 2-inch pieces. This size ensures they cook evenly and hold their shape. Bring a large pot of salted water to a rolling boil - it should taste like the ocean when you dip your finger in.
Add the green beans and cook for exactly 3 minutes. You're not trying to fully cook them - just soften them slightly. Drain immediately in a colander and rinse with cold water to stop the cooking process. This blanching step is crucial as it prevents the beans from becoming mushy when they bake later. Spread them out on a baking sheet and let them cool completely before proceeding.
Make the Creamy Mushroom Mixture
In a large mixing bowl, combine the 2 cans of cream of mushroom soup, 0.5 cup of milk, 0.5 cup of melted butter, 0.25 cup of all-purpose flour, 0.5 tsp of salt, 0.25 tsp of black pepper, and 0.5 tsp of garlic powder. Mix until completely smooth - there should be no lumps remaining. The mixture should be thick but pourable.
For extra richness, stir in the 0.25 cup of heavy cream (if using) and the 0.25 cup of grated parmesan cheese. This is where the magic happens - the combination of these ingredients creates that signature creamy texture that makes this casserole so special. Taste and adjust seasoning if needed, but be careful not to overdo it as the onions will add more flavor later.
Assemble the Casserole
Preheat your oven to 350°F. In a 9x13-inch baking dish, spread the blanched green beans evenly across the bottom. This creates a solid base for your casserole. Pour the creamy mushroom mixture over the green beans, spreading it evenly to the edges of the dish.
Here's where the crispy magic happens: sprinkle the entire surface with the 1 bag of crushed French-fried onions. You want them to cover every inch of the casserole - this is what creates that iconic golden, crispy topping. For extra flavor, mix 0.25 cup of milk with the remaining 0.25 cup of parmesan cheese and drizzle this mixture evenly over the top. This creates a delicious cheesy layer that adds another dimension of flavor.
Bake to Perfection
Place the assembled casserole in the preheated oven and bake for 35-40 minutes. The edges should be bubbling and the top should be a beautiful golden brown color. You're looking for that perfect contrast - crispy onions on top and creamy filling beneath.
For the final touch, broil for 2-3 minutes at the very end. Watch it closely - you want the onions to turn a deep golden brown and become extra crispy. Remove from the oven and let it rest for 5 minutes before serving. This resting time allows the layers to set and makes it easier to slice cleanly. Serve warm with a side of dinner rolls for the ultimate comfort meal experience.
Pro Tips For Making Betty Crocker Green Bean Casserole
- Trim and Blanch Beans: Cut the ends off those green beans—yes, even the thick ones—and give them a quick 2-minute blanch in boiling water before tossing with the soup. This stops them from turning mushy later, and the texture stays crisp-tender. (I learned this the hard way after serving a batch that felt like it had been steamed for an hour.)
- Stir the Soup: The cream of mushroom soup can separate when heated—don’t just dump it in and walk away. Whisk it into the milk and butter first, then mix it into the beans while they’re still hot. This keeps the sauce silky instead of lumpy. (Your future self will notice the difference.)
- Don’t Skip the Butter: That extra tablespoon of butter in the soup mixture isn’t optional—it’s what makes the casserole rich and the onions crispier when they toast. Use unsalted so you control the seasoning, and melt it into the warm soup, not cold. (I used to skip it; now I don’t.)
- Toast Onions Low and Slow: Spread those French-fried onions on a baking sheet and bake them at 300°F for 8–10 minutes before sprinkling on top. Low heat keeps them from burning instantly and gives them a deeper, nuttier crunch. (Yes, it’s slower, but the result is worth it.)
Perfect pairings for this dish
Classic Holiday Sides
This casserole pairs beautifully with roast turkey for Thanksgiving, creating a nostalgic centerpiece. I always serve it alongside garlic mashed potatoes—the creamy texture contrasts perfectly with the crispy onions. For Christmas, add cornbread for a Southern twist that soaks up every creamy bite. 🍗
For a lighter option, serve with simple green salad and herb-roasted carrots to balance the richness. The acidity of the salad cuts through the creamy sauce beautifully. I like using arugula with lemon vinaigrette to keep it fresh and vibrant alongside the warm casserole.
Protein Pairings
Add ground beef or sausage to the green beans before baking for a heartier main course. Brown 1 lb of ground beef with 1 tsp garlic powder and ½ tsp smoked paprika, then mix it into the soup layer. This turns the casserole into a satisfying one-dish meal. 🥩
For seafood lovers, try topping with grilled salmon or shrimp scampi after baking. The briny flavors complement the creamy mushroom sauce wonderfully. I often serve it with lemon-dill rice to round out the meal.
Beverage Pairings
A bold red wine like Cabernet Sauvignon stands up to the richness of the dish. The tannins cut through the creaminess beautifully. For a lighter option, Chardonnay with its buttery notes enhances the mushroom flavor. 🍷
For non-alcoholic options, sparkling apple cider adds a refreshing contrast. I also love serving it with iced tea—the sweetness balances the savory flavors perfectly. A cold root beer float with vanilla ice cream makes a fun dessert pairing too!
Make-Ahead Tips
Assemble the casserole a day ahead and refrigerate uncovered. This helps the onions dry slightly, making them extra crispy when baked. Cover tightly with foil and bake straight from the fridge—just add 10-15 extra minutes to the cooking time. 🕒
For potlucks, bake in individual ramekins (8x8-inch) so guests can take their own servings. Preheat the ramekins in the oven for 10 minutes before adding the mixture to ensure even baking. This keeps the texture perfect even when transported.

Frequently asked questions
Can I use frozen green beans instead of fresh?
Yes, but with one key adjustment: thaw and drain the frozen beans first, then pat them completely dry with paper towels. This prevents excess moisture from making the casserole soggy. Use 2 cups frozen beans (about 12 oz) instead of 2 lbs fresh—they're more concentrated.
Why did my French-fried onions get soggy?
This usually happens when the onions absorb moisture from the creamy layer. To fix it, sprinkle them fresh after baking (not during) and broil for 2-3 minutes at the very end. For extra insurance, mix 1 tablespoon cornstarch into the crushed onions before topping.
Can I make this dish ahead for Thanksgiving?
Assemble it 1-2 days ahead and refrigerate uncovered. The onions will dry slightly, making them extra crispy when baked. Add 10-15 minutes to baking time if starting cold. For potlucks, bake in individual ramekins (8x8-inch) for easy serving.
What can I substitute if I don't have cream of mushroom soup?
Make a quick homemade version: blend 1 cup cooked mushrooms, 1 cup milk, 2 tablespoons butter, and 1 tablespoon flour until smooth. For extra richness, add ½ cup sour cream. This mimics the creamy texture while keeping the classic flavor.
How do I make this dish lower in calories?
Swap the butter for Greek yogurt or light cream cheese, reduce the milk to ¼ cup, and use low-fat cheese. Top with baked onion rings instead of fried onions (bake at 400°F for 10 minutes** before adding to the casserole). This cuts calories by ~30% while keeping the creamy texture.
