Let me show you how to capture that perfect balance of comfort and flavor.

What Ingredients Are in a Green Bean Casserole?
Making a truly memorable green bean casserole starts with quality ingredients, and living in Wisconsin means access to some of the freshest produce and dairy around. While my grandmother’s original recipe called for canned everything, this modern take elevates the dish by using fresh, local ingredients that would still make her proud.
- 2 pounds fresh green beans, trimmed
- 1 pound fresh mushrooms, sliced (cremini or button)
- 1 large yellow onion, for the homemade crispy topping
- 3 cups whole milk
- 4 tablespoons Wisconsin butter
- 1/3 cup all-purpose flour
- 2 cloves garlic, minced
- 1 cup Wisconsin sharp cheddar cheese, shredded
- 1/2 cup heavy cream
- 2 teaspoons fresh thyme
- 1 teaspoon kosher salt
- 1/2 teaspoon black pepper
- 1/4 teaspoon nutmeg
- Vegetable oil for frying onions
Let’s talk substitutions for a moment because sometimes we need to work with what we have. While fresh green beans are ideal, frozen ones can work in a pinch – just avoid canned beans, which tend to become mushy.
For those looking to make this ahead of time, all components can be prepared separately up to two days in advance, though the crispy onions should be stored in an airtight container to maintain their crunch.
And for my dairy-sensitive friends, plant-based alternatives can work here, though the sauce might need a bit more seasoning to achieve that same rich depth.
How to Make this Green Bean Casserole
Start by blanching 2 pounds of fresh green beans in well-salted boiling water until bright green and crisp-tender, about 3-4 minutes, then shock them in an ice bath.
While the beans cool, prepare the star of the show – those irresistible crispy onions. Slice 1 large yellow onion into thin rings, dredge in seasoned flour, and fry in batches in hot vegetable oil until golden brown and perfectly crunchy.
For the creamy mushroom sauce, start by sautéing 1 pound of sliced mushrooms in 4 tablespoons of Wisconsin butter until they release their moisture and turn golden brown.
Add 2 cloves of minced garlic and cook until fragrant, then sprinkle in 1/3 cup flour to make a roux. Gradually whisk in 3 cups whole milk and 1/2 cup heavy cream, stirring constantly to prevent lumps.
Once the sauce starts to thicken, fold in 1 cup of shredded Wisconsin sharp cheddar, 2 teaspoons fresh thyme, and the holy trinity of seasonings – 1 teaspoon kosher salt, 1/2 teaspoon black pepper, and that secret weapon, 1/4 teaspoon nutmeg.
Time to bring it all together in a 9×13 baking dish. Combine the blanched green beans with the mushroom sauce, making sure every bean gets a proper coating.
For best results, use a premium Dutch oven to achieve even heat distribution and a perfectly bubbling casserole every time.
Top with those homemade crispy onions and pop it into a 350°F oven for about 25-30 minutes, until the sauce is bubbling and the onions are a shade darker.
Let it rest for 5-10 minutes before serving – though keeping enthusiastic hands away from those crispy onions during the wait might be the biggest challenge of all.
Green Bean Casserole Substitutions and Variations
While this classic green bean casserole recipe is pretty perfect as-is, there’s always room to play around with substitutions and variations to match your pantry or preferences.
I’d suggest swapping in fresh Wisconsin mushrooms for canned ones, or using local cream of mushroom soup from small-batch producers. Can’t find French’s fried onions? Crispy shallots work beautifully.
For a heartier twist, I love adding crumbled bacon or diced ham. And here’s a game-changer – throwing in some Wisconsin sharp cheddar adds an amazing depth.
Feel free to mix up the green beans too – haricots verts or garden-fresh beans are wonderful alternatives.
What to Serve with Green Bean Casserole
Green bean casserole pairs beautifully with so many classic main dishes, you’ll never run out of delicious combinations.
I love serving it alongside a juicy roasted turkey, especially using Wisconsin-raised birds from local farms. For everyday meals, it’s perfect next to meatloaf, roasted chicken, or my family’s favorite – pan-seared pork chops with fresh apple compote.
Looking for something different? Try it with grilled salmon or, for vegetarian options, stuff it inside portobello mushrooms.
The creamy, crunchy texture complements practically any protein. And those crispy onions on top? They’re basically little flavor bombs that make everything better.

After making this comforting casserole countless times, I’ve come to appreciate how it brings families together around the dinner table, just like it does in my own home with my three daughters.
There’s something magical about those crispy fried onions mixing with creamy mushroom sauce and fresh Wisconsin green beans that makes everyone ask for seconds.
Whether it’s a holiday gathering or just Sunday dinner, this humble dish carries the warmth of family traditions.
I love seeing how each family adds their own twist while keeping the heart of the recipe intact.
Some comfort foods just can’t be improved upon – they’re perfect in their simplicity.
