What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver a bold flavor and satisfying texture without the fuss. Most of them are pantry staples, so you’re likely to have them on hand!

• Fresh green beans: Trimmed and cut into bite-sized pieces. You can substitute frozen green beans if needed.
• Cream of mushroom soup: Use canned or homemade—just make sure it’s rich and creamy.
• Milk: Whole milk or any unsweetened milk alternative works fine.
• Shredded cheddar cheese: Adds a nice cheesy layer to the casserole.
• French fried onions: The crispy topping is a must—don’t skip this! (I love using [insert favorite brand here].)
• Salt and black pepper: For seasoning the dish perfectly.
• Garlic powder: Adds a subtle savory depth to the dish.
• Worcestershire sauce: Just a splash for an extra kick of umami flavor.

If you want to go the extra mile, you can toss in some cooked, crumbled bacon or sautéed mushrooms for added flavor. For a healthier twist, you can swap the French fried onions for panko breadcrumbs or crushed nuts for a lighter crunch.

Equipment Needed

No fancy gadgets are required for this recipe. Here’s what you’ll need:

• Large pot: To blanch the green beans.
• Mixing bowl: For combining the creamy sauce.
• Whisk: To mix the soup and milk smoothly.
• Spatula: For evenly spreading the green beans and sauce.
• 9×13-inch casserole dish: The perfect size to bake this recipe.

If you don’t have a casserole dish, a deep baking pan will work just as well. And if you’re short on time, you can use pre-washed and trimmed green beans to save a step.

Preparation Method

1. Preheat your oven to 350°F (175°C). This ensures your casserole bakes evenly and develops a bubbling, golden crust.
2. Prepare the green beans by trimming off the ends and cutting them into bite-sized pieces. If using frozen green beans, thaw them beforehand.
3. Bring a large pot of salted water to a boil. Add the green beans and blanch them for 3-4 minutes, then drain and rinse with cold water to stop the cooking process.
4. In a mixing bowl, combine 1 can (10.5 ounces) of cream of mushroom soup, 1/2 cup (120 ml) of milk, 1 teaspoon garlic powder, 1/2 teaspoon salt, 1/4 teaspoon black pepper, and a splash of Worcestershire sauce. Whisk until smooth.
5. Add the blanched green beans to the mixing bowl and stir until they are evenly coated with the creamy mixture.
6. Grease your 9×13-inch casserole dish with butter or cooking spray. Pour the green bean mixture into the dish and spread it out evenly.
7. Sprinkle 1 cup (120 g) of shredded cheddar cheese over the green beans. This adds a delicious layer of flavor.
8. Top the casserole with 1 cup (70 g) of French fried onions, spreading them evenly across the surface.
9. Bake the casserole in the preheated oven for 25-30 minutes or until the top is golden and bubbly. Your kitchen will smell amazing!
10. Remove from the oven and let it cool for 5 minutes before serving. This helps the casserole set and makes it easier to scoop.

Pro Tip: If you like your green beans extra tender, you can blanch them for an additional minute or two. Just be sure not to overdo it, as you don’t want them to turn mushy.

Cooking Tips & Techniques

Here are some tips to make sure your classic southern green bean casserole turns out perfectly every time:

• Blanch your beans: Don’t skip this step! It helps retain that fresh, vibrant color and keeps the beans tender-crisp.
• Go heavy on the seasoning: If you want to add extra flavor, sprinkle in some onion powder, smoked paprika, or even a pinch of cayenne for a little heat.
• Choose fresh green beans: While frozen green beans work well, fresh ones have unbeatable flavor and texture.
• Don’t skimp on the fried onions: This topping is the star of the show, so be generous for that irresistible crunch.
• Customize the cheese: If cheddar isn’t your thing, try a mix of Gruyère, mozzarella, or even Parmesan for a unique twist.

One mistake I made early on was forgetting to drain the green beans well after blanching—don’t be like me! Excess water can make your casserole soupy, so take the extra time to pat them dry if needed. And if you’re in a rush, you can assemble the casserole ahead of time and refrigerate it until you’re ready to bake!

Variations & Adaptations

This classic southern green bean casserole recipe is as versatile as it is delicious. Here are some fun ways to make it your own:

• Make it healthier: Swap the cream of mushroom soup for a homemade version made with almond milk or low-fat milk. You can also use whole wheat breadcrumbs or crushed nuts instead of fried onions.
• Seasonal twist: Add roasted chestnuts or sautéed mushrooms for a holiday-inspired variation. In the summer, toss in fresh cherry tomatoes for a lighter, brighter flavor.
• Spice it up: Add a teaspoon of Cajun seasoning or crushed red pepper flakes to the creamy sauce for a kick of heat.
• Vegetarian swap: Use a vegetarian-friendly mushroom soup and skip the Worcestershire sauce, or use a vegetarian alternative.

My personal favorite variation? Adding crispy bacon bits to the topping before baking. The smoky flavor takes this dish to the next level and makes it even more irresistible!

Serving & Storage Suggestions

This classic southern green bean casserole is best served warm and fresh from the oven. Here’s how to make it shine:

• Serving temperature: Serve immediately after baking while the topping is crunchy and the casserole is piping hot.
• Presentation: Sprinkle a few extra fried onions on top right before serving, and garnish with a pinch of chopped fresh parsley for a pop of color.
• Pairing ideas: Serve alongside roasted turkey, honey-glazed ham, or even grilled chicken. It’s also great with cornbread or dinner rolls.
• Storage: Store leftovers in an airtight container in the refrigerator for up to 3 days.
• Reheating: Warm in the oven at 350°F (175°C) for about 10 minutes or until heated through. You can also microwave individual portions—just keep in mind the topping may lose some crispness.

If you’re planning ahead, you can assemble the casserole the night before and store it covered in the fridge. Just add the fried onions right before baking for best results.
