Ingredients You’ll Need

Simple ingredients, BIG flavor:

4 cups fresh or frozen green beans, trimmed
1 tablespoon butter
1 small onion, finely chopped
2 cups sliced mushrooms
2 cloves garlic, minced
1 cup chicken or vegetable broth
1 cup heavy cream or whole milk
1 tablespoon flour (for thickening)
Salt & pepper, to taste
1 ½ cups crispy fried onions (store-bought or homemade)

How to Make It

1. Prep the Green Beans

Boil or steam the green beans for 4–5 minutes until they’re bright green and slightly tender.
Drain and set aside.

2. Make the Creamy Sauce

Heat butter in a pan.
Add onions and sauté until soft.
Add mushrooms and garlic; cook until the mushrooms release their moisture.
Sprinkle flour and stir for 1 minute.
Pour in broth and cream.
Let it simmer until thick and creamy.

Season with salt and pepper.

3. Combine Everything

Add the cooked green beans into the sauce and mix well.
Pour into a casserole baking dish.

4. Add the Crunch

Sprinkle crispy fried onions generously on top.

5. Bake

Bake at 375°F (190°C) for 20–25 minutes, or until the top is golden brown and bubbling.

Tips for the Perfect Casserole

✨ Use fresh green beans for the best texture
✨ Don’t skip the mushroom step — it adds deep flavor
✨ Add extra crispy onions right before serving if you love crunch
✨ Make it ahead: assemble the casserole without the onions and refrigerate up to 24 hours; add onions and bake when ready

Serving Suggestions

This casserole pairs beautifully with:

Roast chicken
Turkey
Mashed potatoes
Stuffing
Honey-glazed carrots

Or honestly… eat it with a spoon straight from the dish. Zero judgment.

Why This Recipe Stands Out

Green bean casserole is a classic, but many versions turn out too mushy or bland.
This recipe brings:

Homemade flavor without extra work
Balanced creaminess
A topping that stays crispy
A fresh taste from real vegetables

Your guests will never guess how easy it was to make!
