Green Bean Casserole

Homemade green bean casserole with creamy mushroom sauce and crispy fried shallots in a white baking dish.

We’re grown. We use real mushrooms now. And crispy shallots. Amen.

🪑 A Little Southern Realness...(from scratch, of course)

Look, we all grew up on the cream-of-mushroom version, and no shade to it—she held it down for decades. But we’re not doing that anymore. We’re grown. We season our food. We use real ingredients. And if we’re bringing a casserole to the table, it’s gonna be fresh, creamy, savory, and crunchy in all the right places.

This from-scratch Green Bean Casserole has tender green beans, a homemade mushroom cream sauce (yes, you can do it), and crispy shallots on top that make you wanna double up on your serving. Trust me, once you do it this way, there’s no going back.

🍴 Servings:

Serves 8–10

Prep Time: 20 minutes
Cook Time: 30 minutes
Total Time: 50 minutes

🛒 Grocery List:

For the base:

  • 1 ½ lbs fresh green beans, trimmed and halved

  • 2 tablespoons unsalted butter

  • 8 oz cremini or button mushrooms, sliced

  • 3 cloves garlic, minced

  • 1 small onion, finely diced

  • 2 tablespoons all-purpose flour

  • 1 cup chicken or vegetable broth

  • 1 cup half-and-half or heavy cream

  • Salt and pepper to taste

  • Pinch of nutmeg (optional but so good)

For the topping:

  • 2 large shallots, thinly sliced

  • ½ cup all-purpose flour

  • Vegetable oil, for frying

  • Salt, to finish

👩‍🍳 Directions:

1. Blanch the green beans:

Boil green beans in salted water for 3–4 minutes until just tender. Drain and immediately transfer to an ice bath to stop the cooking. Set aside.

2. Make the mushroom sauce:

In a large skillet, melt butter over medium heat. Add mushrooms and onions, cooking until soft and golden—about 8–10 minutes. Stir in garlic and cook 1 more minute. Sprinkle in flour and cook for another 2 minutes.

Slowly whisk in broth, then cream. Simmer until thickened, about 5 minutes. Season with salt, pepper, and a pinch of nutmeg if using.

3. Fry the shallots:

Toss shallots in flour. Heat about ½ inch of vegetable oil in a skillet over medium-high heat. Fry shallots in batches until golden and crisp, then drain on paper towels and sprinkle with salt.

4. Assemble and bake:

Preheat oven to 375°F (190°C). Combine green beans and sauce in a greased 9x13 baking dish. Top with crispy shallots. Bake uncovered for 20–25 minutes until bubbly and golden.

📝 Southern Tip:

Fry the shallots fresh.
Don’t skip this step—it makes all the difference. They’re salty, crunchy, and way better than anything from a can.

💡 Serve It With:

  • Turkey, dressing, and gravy (you know the drill)

  • Sweet potato casserole

  • Mac & cheese if you’re feeling extra

  • A side-eye for whoever still brings canned soup to the party 😘

With real mushrooms and real standards,
Southern Charm Style 🫛✨
