The Essential Ingredients for the Best Casserole

This recipe uses a handful of high-quality, fresh ingredients to create its signature creamy, savory, and crunchy texture.

• Fresh Green Beans: The star of the show. Using fresh, crisp green beans is the key to a superior casserole. We blanch them first, which is a simple technique that leaves them perfectly tender-crisp and locks in their beautiful, vibrant green color.
• The Savory Flavor Base (Bacon, Peppers & Onions): This trio builds an incredible foundation of flavor. We render crisp, smoky bacon and then sauté sweet red bell pepper, onion, and pungent garlic in the delicious bacon fat.
• The From-Scratch Cream Sauce: This is what sets this recipe apart.
  • The Roux (Butter & Flour): A simple paste made from melted butter and all-purpose flour is the classic French foundation for a stable, thick, and creamy sauce.
  • Milk & Half-and-Half: A combination of whole milk and rich half-and-half creates a sauce that is both perfectly creamy and luxuriously rich.
  • Sharp Cheddar Cheese: For the best, most intense cheese flavor and smoothest texture, it is crucial to use a good quality block of sharp Cheddar cheese that you grate yourself.
• The Crispy Topping (Panko Breadcrumbs): Instead of the traditional canned fried onions, we use panko breadcrumbs. These Japanese-style breadcrumbs are flakier and lighter than regular breadcrumbs, and they toast up to a wonderfully light, airy, and super-crispy texture.

Step-by-Step to a Perfect Green Bean Casserole

Follow these detailed steps to create a truly perfect, classic, and comforting side dish.

Part 1: Blanch the Fresh Green Beans

Step 1: First, preheat your oven to 350°F (175°C). Prepare a large bowl of ice water and set it aside.

Step 2: Bring a large pot of lightly salted water to a rolling boil. Add your trimmed, fresh green beans and let them cook for just 3 to 4 minutes.

Step 3 (The Shock!): Immediately remove the green beans from the boiling water with a slotted spoon and plunge them directly into the bowl of ice-cold water. Let them sit in the ice water until they are completely cool.

Pro Tip: This process, called “blanching and shocking,” is a professional secret. It par-cooks the beans so they are perfectly tender-crisp in the final casserole, and the ice bath immediately stops the cooking process, locking in their beautiful, vibrant green color.

Step 4: Drain the cooled beans well and set them aside.

Part 2: Cook the Savory Bacon and Vegetable Base

In a large skillet over medium heat, add the 4 slices of chopped bacon. Cook for about 2 minutes, then add the diced peppers, garlic, and onions. Continue to cook, stirring, for another 3 to 5 minutes, until the bacon is cooked through (but not overly crisp) and the onions are soft and golden brown. Remove the skillet from the heat and set it aside.

Part 3: Create the Creamy From-Scratch Cheese Sauce

Step 1 (The Roux): In a separate, medium saucepan, melt the 4 tablespoons of butter over medium heat. Sprinkle the 4 tablespoons of all-purpose flour into the pan and whisk it immediately into the butter to form a thick, smooth paste. Cook this “roux,” whisking constantly, for 1 to 2 minutes to cook out the raw flour taste.

Step 2 (The Béchamel): While whisking constantly, slowly pour in the 2 1/2 cups of milk and the 1/2 cup of half-and-half. Continue to whisk until the sauce is smooth. Let the sauce cook, whisking often, as it thickens and comes to a simmer, which will take about 2 minutes.

Step 3 (The Mornay): Add the 1 1/2 teaspoons of salt, some freshly ground black pepper, and the cayenne pepper. Then, add the 1 cup of grated sharp Cheddar cheese. Turn off the heat and stir until the cheese is completely melted and the sauce is smooth and velvety.

Part 4: Combine, Top, and Bake to Perfection

Step 1: Add the cooked bacon and onion mixture to your beautiful cheese sauce and stir to combine. Then, add the blanched and drained green beans and stir gently until everything is evenly coated in the creamy sauce.

Step 2: Pour the entire mixture into a 9×13-inch baking dish and spread it into an even layer.

Step 3: Top the casserole evenly with the 1 cup of panko breadcrumbs.

Pro Tip: For an even richer and more golden-brown topping, you can toss the panko breadcrumbs with 1-2 tablespoons of melted butter before sprinkling them on top.

Step 4: Bake for about 30 minutes, until the sauce is hot and bubbly and the panko topping is a beautiful, deep golden brown.

Let the casserole sit for 10 minutes before serving. This allows the hot, creamy sauce to set up slightly.

Storage and Make-Ahead Tips

This from-scratch Green Bean Casserole is the perfect make-ahead dish for a stress-free holiday.

• Make-Ahead: You can assemble the entire casserole (without the panko topping) up to 2 days in advance. Let the green bean and sauce mixture cool completely, place it in your baking dish, cover tightly, and refrigerate. Prepare the topping and store it in a separate airtight container at room temperature. When ready to bake, sprinkle the topping over the casserole and bake as directed (you may need to add 10-15 minutes to the baking time).
• Storage: Store any leftover casserole, covered, in the refrigerator for up to 4 days.
• Reheating: The best way to reheat the casserole is in a 350°F oven until it is hot and bubbly. This will also help to re-crisp the topping.

Creative Recipe Variations

This wonderful from-scratch recipe is a fantastic base for your own delicious and creative twists.

1. The Classic Mushroom Twist: To get that classic, traditional “cream of mushroom” flavor, simply sauté 8 ounces of sliced cremini mushrooms in the skillet along with the onions and peppers until they are deeply browned.
2. Use a Different Cheese: While the sharp cheddar is delicious, you can create a more sophisticated flavor profile by substituting it with an equal amount of a nutty Gruyère cheese or a rich and creamy Fontina cheese.
3. Make it a Vegetarian Green Bean Casserole: For a delicious vegetarian version, simply omit the bacon. You will want to sauté the vegetables in about 3 to 4 tablespoons of butter or olive oil instead of the bacon fat. To add a smoky flavor, you can add 1/2 teaspoon of smoked paprika to the cream sauce.
