Step‑by‑Step Instructions for Ina Garten’s Gourmet Green Bean Casserole
Step 1: Preparation
Start by preheating your oven to 350°F (175°C). While the oven is warming, trim the ends of the fresh green beans and cut them into roughly two-inch pieces. Gather all your ingredients, including sliced mushrooms, chopped onions, heavy cream, and grated Gruyère cheese, so you have everything ready for assembly.
Step 2: Sauté
In a large skillet over medium heat, drizzle in olive oil and add the chopped onions. Sauté for about 5-7 minutes until they’re translucent and fragrant. Then, add the sliced mushrooms to the skillet, cooking for an additional 5 minutes until they are tender and slightly browned, releasing their delicious umami flavor into your kitchen.
Step 3: Combine Ingredients
Once your onions and mushrooms are beautifully sautéed, pour in the heavy cream, followed by a generous sprinkle of salt and pepper to taste. Stir the mixture thoroughly, letting the flavors meld together. Then, add the chopped fresh green beans, gently folding them into the creamy mixture until they are well coated.
Step 4: Transfer to Baking Dish
Carefully pour the green bean mixture into a greased baking dish, spreading it evenly to ensure even cooking. The vibrant colors from the green beans and creamy sauce should entice your senses. This is where the magic of Ina Garten’s Gourmet Green Bean Casserole begins to take shape!
Step 5: Add Toppings
Sprinkle the grated Gruyère cheese generously over the top of the casserole, followed by a layer of crispy fried onions. This final touch adds a delightful crunch and an irresistible golden brown color, ensuring your casserole will have both texture and visual appeal when it comes out of the oven.
Step 6: Bake
Place the baking dish in the preheated oven and let it bake for 30 minutes. Keep an eye on it as it cooks; you’ll know it’s ready when the top is golden brown and bubbly, filling your kitchen with mouthwatering aromas that are sure to draw everyone to the table.
Step 7: Rest & Serve
Once baked, remove the casserole from the oven and let it cool for about 5-10 minutes to allow it to set. This resting time will help you serve the perfect slices of Ina Garten’s Gourmet Green Bean Casserole, beautifully creamy with a satisfying crunch, ready to be enjoyed by family and friends!

Ina Garten’s Gourmet Green Bean Casserole Recipe FAQs
How do I choose fresh green beans?
