Timing

One reason Green Bean Casserole is so popular is its efficient timing.

• Preparation time: 15 minutes
• Cooking time: 30 minutes
• Total time: 45 minutes

Step-by-Step Instructions

Step 1: Prepare the Green Beans

Wash and trim fresh green beans, then blanch them in boiling salted water for 3–4 minutes. This keeps them vibrant and tender-crisp. Drain and pat dry to prevent excess moisture.

Tip: Avoid overcooking here green beans continue cooking in the oven.

Step 2: Make the Creamy Base

In a large bowl, mix cream of mushroom soup, milk, melted butter, garlic powder, salt, and black pepper until smooth and glossy.

Tip: If the mixture feels too thick, add milk one tablespoon at a time.

Step 3: Combine Beans and Sauce

Gently fold the green beans into the creamy mixture, ensuring every piece is coated evenly for consistent flavor.

Tip: Folding instead of stirring keeps the beans intact and prevents mushy texture.

Step 4: Transfer to Baking Dish

Spread the mixture evenly into a greased casserole dish. Smooth the top for even baking.

Tip: A shallow dish helps moisture evaporate, improving overall creaminess.

Step 5: First Bake

Bake uncovered at 180°C (350°F) for 20 minutes. This allows flavors to blend and the sauce to thicken naturally.

Step 6: Add Crispy Topping

Remove the dish and sprinkle fried onions evenly over the top.

Tip: Add toppings halfway to prevent burning and maintain crunch.

Step 7: Final Bake and Rest

Return to the oven for 10 minutes until golden and bubbling. Let it rest 5 minutes before serving to set the sauce perfectly.
