How to Make Best-Ever Green Bean Casserole
Follow these simple steps to prepare this delicious Best-Ever Green Bean Casserole:
Step 1: Prepare Your Oven
Preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius). This crucial initial step ensures even cooking for the casserole.
Step 2: Sauté Aromatic Goodness
In a large skillet over medium heat, melt the butter. Add the finely diced onion and sliced mushrooms, stirring occasionally until they soften and become fragrant. After about 5—7 minutes, toss in the minced garlic, giving it 1-2 minutes until it’s just golden.
Step 3: Blanch Those Beans
In a medium saucepan, combine the fresh green beans and low-sodium chicken broth. Bring to a boil and cook for about 8 minutes until the beans are crisp-tender. Drain and set aside; no one wants mushy beans in their casserole!
Step 4: Combine the Ingredients
In a large mixing bowl, combine the sautéed onion and mushroom mixture with the cream of mushroom soup, cooked green beans, grated Parmesan cheese, salt, and black pepper. Stir well to ensure everything is mixed thoroughly.
Step 5: Transfer to Baking Dish
Spray a 2-quart baking dish with nonstick cooking spray. Pour the combined mixture into the baking dish, spreading it evenly. Now, the pièce de résistance: top it generously with crispy onion strings!
Step 6: Bake It to Perfection
Place the baking dish in your preheated oven and bake for about 20 minutes. You’re looking for the casserole to be heated through and the top to achieve a delightful golden-brown, crunchy finish that no one will be able to resist.
