How to Make Ultimate Green Bean Casserole
Preheat the oven at 350 °F. Start by creating a warm environment for your casserole to bake beautifully, ensuring it s evenly cooked throughout.
Blanch the green beans in a large stock pot filled with boiling water for 3-4 minutes. Quickly transfer them to a bowl of ice water to halt the cooking. Once cooled, drain well and transfer to a separate bowl.
Saut the mushrooms by melting butter in a large saut pan over medium heat. Cook the sliced crimini mushrooms for about 5-10 minutes, stirring until they turn golden brown. Add minced garlic and continue cooking for 1-2 minutes until fragrant.
Mix together the creamy base in a large bowl by combining the soup, half and half, soy sauce, and thyme sprigs. Stir gently to ensure everything is well incorporated, creating a luscious mixture ready to bind your casserole.
Combine the soup mixture, saut ed mushrooms, half of the crispy onions, and green beans all together. Transfer the delicious mixture to a large casserole dish. Cover with foil to keep the moisture in and bake it in the preheated oven for 20 minutes.
Uncover the casserole, sprinkle the remaining crispy onions on top, and bake for an additional 5-10 minutes, or until the onions are golden brown and the casserole is bubbling with excitement!
Optional: Garnish with additional fresh thyme sprigs for a pop of color and flavor!

Expert Tips for Ultimate Green Bean Casserole
Fresh Beans Matter: Use fresh, seasonal green beans for the best texture and flavor. Canned beans may lead to a mushy casserole.
Saut for Flavor: Take your time when saut ing the mushrooms; browning them well enhances the umami in your ultimate green bean casserole recipe.
Don t Overbake: Keep an eye on the casserole during the last baking phase. Remove it when bubbly and golden to prevent dryness.
Customize Your Topping: Feel free to add other toppings like breadcrumbs or cheese for a personal twist beyond the crispy onions.
Thyme s the Charm: Fresh thyme is ideal for its vibrant taste, but if unavailable, use just a pinch of dried thyme instead to avoid overpowering.
