What Kind of Green Beans Should I Use for Homemade Green Bean Casserole?
Fresh green beans are the best choice for Homemade Green Bean Casserole because they maintain a bright color and crisp-tender texture after baking. Trim the ends and blanch them briefly before assembling the casserole for the best results.
Frozen green beans are another excellent option when fresh beans aren’t available. Thaw and drain them well before using to prevent excess moisture.
Canned green beans can be used in a pinch, but they have a much softer texture. Fresh or frozen green beans produce a more flavorful and visually appealing casserole.

Ingredients for Homemade Green Bean Casserole
For the Casserole
- 2 pounds fresh green beans, trimmed
- 2 tablespoons unsalted butter
- 1 tablespoon olive oil
- 1 medium onion, finely diced
- 8 ounces mushrooms, sliced
- 3 cloves garlic, minced
- 3 tablespoons all-purpose flour
- 1½ cups chicken broth
- 1 cup heavy cream
- ½ teaspoon dried thyme
- 1 teaspoon salt
- ½ teaspoon black pepper
For the Topping
- 2 cups crispy fried onions
- ¼ cup grated Parmesan cheese (optional)
Preparation of Homemade Green Bean Casserole
Step 1: Prepare the Green Beans
Bring a large pot of salted water to a boil.
Add the green beans and cook for about 4–5 minutes until they become bright green and slightly tender. Immediately transfer them to a bowl of ice water to stop the cooking process.
Drain the green beans thoroughly and set them aside.
Step 2: Cook the Vegetables
Heat the butter and olive oil in a large skillet over medium heat.
Add the diced onion and sliced mushrooms, cooking for about 6–8 minutes until softened and lightly browned. Stir in the minced garlic and cook for another minute until fragrant.
The vegetables should release their moisture and develop rich flavor.
Step 3: Prepare the Cream Sauce
Sprinkle the flour over the cooked vegetables and stir continuously for about 1–2 minutes.
Gradually whisk in the chicken broth followed by the heavy cream until the mixture becomes smooth.
Add the thyme, salt, and black pepper. Simmer for about 5 minutes until the sauce thickens into a rich, creamy consistency.
Step 4: Combine the Ingredients
Preheat the oven to 350°F (175°C).
Add the blanched green beans to the skillet and gently stir until they are evenly coated with the creamy mushroom sauce.
Transfer the mixture to a lightly greased 9×13-inch baking dish, spreading it into an even layer.
Step 5: Add the Topping
Sprinkle about half of the crispy fried onions over the casserole and gently mix them into the top layer.
Evenly spread the remaining crispy fried onions across the surface. If using Parmesan cheese, sprinkle it over the onions.
This topping creates the casserole’s signature crispy finish.
Step 6: Bake the Casserole
Bake the Homemade Green Bean Casserole for 25–30 minutes, or until the sauce is bubbling around the edges and the topping is golden brown.
If the onions begin browning too quickly, loosely cover the casserole with aluminum foil during the final few minutes of baking.
Remove from the oven once the casserole is hot and bubbly.
Step 7: Serve the Homemade Green Bean Casserole
Allow the casserole to rest for about 5 minutes before serving.
The finished Homemade Green Bean Casserole should have tender green beans, a creamy mushroom sauce, and a crispy golden onion topping.
Serve warm as a delicious side dish for your favorite meals.
