Why This Ina Garten–Style Green Bean Casserole Works

Instead of masking the vegetables, this recipe enhances them. Every bite tastes intentional and well-rounded.
Ingredients
- 1½ pounds fresh green beans, trimmed
- 3 tablespoons unsalted butter
- 1 tablespoon olive oil
- 12 ounces cremini or button mushrooms, sliced
- 2 shallots, finely chopped
- 2 cloves garlic, minced
- 3 tablespoons all-purpose flour
- 1½ cups heavy cream
- ½ cup whole milk
- 1 cup grated Gruyère cheese
- ½ cup freshly grated Parmesan cheese
- 1 teaspoon kosher salt (plus more for boiling)
- ½ teaspoon freshly ground black pepper
- ½ teaspoon fresh thyme leaves (or ¼ teaspoon dried)
- 1 cup crispy fried onions (store-bought or homemade)
Instructions
- Prepare the green beans:
Bring a large pot of generously salted water to a boil. Add the green beans and blanch for 3–4 minutes until bright green and just tender. Drain immediately and transfer to an ice bath to stop the cooking. Drain well and set aside. - Preheat the oven:
Preheat your oven to 375°F (190°C). Lightly butter a medium baking dish. - Sauté the vegetables:
In a large skillet over medium heat, melt the butter with the olive oil. Add the mushrooms and cook for 5–7 minutes until they release their moisture and begin to brown. Add the shallots and cook for another 2 minutes, then stir in the garlic and cook for 30 seconds until fragrant. - Make the sauce:
Sprinkle the flour over the mushroom mixture and stir well. Cook for 1 minute to remove the raw flour taste. Slowly pour in the cream and milk, stirring constantly until the sauce thickens, about 3–4 minutes. - Season and enrich:
Add salt, pepper, thyme, Gruyère, and Parmesan. Stir until the cheeses melt and the sauce is smooth and glossy. - Combine:
Add the drained green beans to the skillet and gently toss to coat evenly with the sauce. - Assemble:
Transfer the mixture to the prepared baking dish and spread evenly. Sprinkle the crispy fried onions over the top. - Bake:
Bake uncovered for 25–30 minutes, until bubbly and golden on top. Let rest for 5 minutes before serving.
Tips for Perfect Results
- Don’t overcook the green beans. They should be just tender before baking, as they’ll continue to cook in the oven.
- Brown the mushrooms well. This step builds deep flavor and prevents a watery casserole.
- Grate your own cheese. Pre-shredded cheese doesn’t melt as smoothly.
- Let it rest. A short rest after baking allows the sauce to set beautifully.
Variations & Customizations
- Make it lighter: Use half-and-half instead of heavy cream.
- Extra crunch: Add toasted panko breadcrumbs mixed with butter to the topping.
- Add protein: Crispy pancetta or bacon bits fold in beautifully.
- Gluten-free: Swap flour for gluten-free all-purpose blend.
- Vegan option: Use plant-based butter, cream, and cheese alternatives with sautéed onions on top.
Serving Suggestions
This casserole pairs perfectly with roasted turkey, prime rib, glazed ham, or roast chicken. It also works beautifully alongside mashed potatoes, stuffing, and cranberry sauce for a complete holiday spread. Leftovers reheat well and even taste better the next day.
