Introduction

While the traditional green bean casserole has long been a staple of holiday tables, the Green Bean Mushroom Pie takes those familiar, earthy flavors and elevates them into a sophisticated, main-course-worthy centerpiece. This dish is a celebration of textures: the snap of fresh green beans, the umami-rich depth of sautéed mushrooms, and the buttery, flaky embrace of a golden pastry crust. It is an “honest” dish—grounding, rustic, and deeply aromatic.

This pie moves away from the “canned” shortcuts of the past, opting instead for a scratch-made velouté infused with garlic and fresh herbs. Encased in a double crust, the filling steams to perfection, allowing the mushrooms to release their savory juices into a thick, creamy sauce. It is the ultimate comfort food for a chilly evening, offering a vegetarian-friendly option that satisfies even the most dedicated meat lovers.

Ingredients

• 1 lb fresh green beans: Trimmed and cut into 1-inch pieces. Blanching them first ensures they stay bright and tender.
• 1 lb cremini or button mushrooms: Sliced; these provide the “meatiness” of the pie.
• 1 large onion: Finely diced to create a sweet, savory base.
• 3 cloves garlic: Minced to add a pungent depth.
• 1/4 cup unsalted butter: For sautéing and creating the roux.
• 1/4 cup all-purpose flour: To thicken the filling into a velvety sauce.
• 1 1/2 cups vegetable broth: Use a high-quality broth for maximum flavor.
• 1/2 cup heavy cream: Adds a luxurious, silky finish to the interior.
• 1 tsp dried thyme: Pairs perfectly with the earthiness of the mushrooms.
• 1/2 tsp salt & 1/4 tsp black pepper: Adjusted to your taste.
• 2 sheets refrigerated pie dough: (One for the base, one for the top).
• 1 egg: Beaten for an egg wash to achieve a golden shine.
