Ingredients

Here’s everything you’ll need to make the best Southern-style green bean casserole for Thanksgiving:

Vegetables:

24 oz fresh green beans trimmed and halved
8 oz baby bella mushrooms sliced
4 medium shallots thinly sliced
1 teaspoon dried thyme
1 tablespoon minced garlic

Sauce & Seasonings:

4 tablespoons unsalted butter
2 tablespoons all-purpose flour
1½ cups chicken broth or vegetable broth for vegetarian option
½ cup heavy cream
½ teaspoon Creole or Cajun seasoning
¼ teaspoon ground nutmeg
½ teaspoon red pepper flakes optional for a Southern kick
Kosher salt and black pepper to taste

Topping:

1 cup crispy fried onions or homemade shallot rings
½ cup Parmesan cheese grated
½ cup panko breadcrumbs
2 tablespoons melted butter

Equipment

To prepare this delicious casserole, you’ll need:
1 Large skillet or sauté pan
1 Medium saucepan
1 Mixing bowl
1 Whisk
1 9x13-inch baking dish
1 colander (for draining green beans)
1 Cutting board and knife
1 Measuring spoons and cups
1 Wooden spoon or spatula

Method

Step 1: Preheat and Prep the Beans

Preheat your oven to 375°F (190°C).
Bring a large pot of salted water to a boil. Add the green beans and cook for 4–5 minutes until bright green and slightly tender.
Drain and immediately plunge them into an ice water bath to stop cooking and preserve their color. Drain again and set aside.

Step 2: Sauté the Vegetables

In a large skillet, melt 2 tablespoons of butter over medium heat. Add the sliced shallots and cook for 2–3 minutes, until lightly caramelized.
Add the mushrooms and minced garlic; sauté for another 5–6 minutes, until the mushrooms are tender and golden.
Sprinkle in the thyme, nutmeg, salt, pepper, and red pepper flakes. Stir to combine, letting the aromatics bloom.

Step 3: Make the Creamy Sauce

Add the remaining 2 tablespoons of butter to the skillet. Once melted, sprinkle in the flour and whisk for about 1 minute to create a roux.
Gradually pour in the chicken broth while whisking continuously to prevent lumps.
Add the heavy cream and continue to cook for 3–4 minutes, stirring until the sauce thickens and becomes smooth.
Taste and adjust seasoning — it should be savory, creamy, and well-balanced with a touch of spice.

Step 4: Combine and Assemble

Add the blanched green beans to the skillet and toss gently to coat them evenly with the sauce.
Pour the mixture into a greased 9x13-inch baking dish. Spread it out evenly with a spatula.

Step 5: Prepare the Southern Topping

In a small bowl, combine crispy fried onions, Parmesan cheese, panko breadcrumbs, and melted butter. Stir until well mixed.
Sprinkle this topping evenly over the casserole.
For a more homemade touch, you can fry your own shallot rings by coating them lightly in flour and sautéing until crisp and golden.

Step 6: Bake to Golden Perfection

Place the casserole in the preheated oven and bake for 25–30 minutes, or until bubbly and golden on top.
If the top browns too quickly, cover loosely with foil for the last 10 minutes of baking.

Step 7: Serve and Enjoy

Remove from the oven and let it rest for 5 minutes before serving.
Garnish with fresh parsley or thyme for a pop of color.
Serve warm — creamy inside, crispy on top, and absolutely irresistible.

Notes

🧊 Storage & Reheating

Storage:

Store leftovers in an airtight container in the refrigerator for up to 4 days.

For quick reheating, microwave individual portions for 1–2 minutes.

Freezing:

Assemble the casserole without the topping, wrap tightly, and freeze for up to 2 months.

Add the topping and bake fresh when ready to serve.
