INGREDIENTS
- 2 pounds fresh green beans, trimmed and cut into 2-inch pieces
- 8 slices thick-cut bacon, chopped
- 1 medium onion, finely diced
- 2 cloves garlic, minced
- 8 ounces mushrooms, sliced (cremini or button work great)
- 2 tablespoons all-purpose flour
- 1 cup chicken broth
- 1 cup heavy cream
- 1/4 cup grated Parmesan cheese
- 1 teaspoon fresh thyme leaves
- 1/2 teaspoon salt (or to taste)
- 1/4 teaspoon black pepper
- 1/8 teaspoon nutmeg (optional, but recommended)
- 1 1/2 cups crispy fried onions, divided
INSTRUCTIONS
First, preheat your oven to 375°F (190°C) and bring a large pot of salted water to a boil. Add the green beans and blanch them for about 5 minutes until they’re bright green and slightly tender but still have some crunch.
Immediately drain and plunge them into ice water to stop the cooking process. Once cooled, drain thoroughly and set aside.
In a large skillet or Dutch oven, cook the chopped bacon over medium heat until crispy, about 8-10 minutes. Remove about 2 tablespoons of the bacon pieces with a slotted spoon and set aside for topping later.
Leave the bacon grease in the pan and add the diced onion. Cook for about 4 minutes until softened, then add the garlic and mushrooms.
Cook for another 5-7 minutes until the mushrooms have released their moisture and begun to brown.
Sprinkle the flour over the mixture and stir constantly for about 1 minute to cook out the raw flour taste. Slowly pour in the chicken broth while stirring continuously to prevent lumps.
Add the heavy cream and bring the mixture to a simmer, stirring occasionally until it starts to thicken, about 3-4 minutes.
Stir in the Parmesan cheese, thyme, salt, pepper, and nutmeg if using.
Fold in the blanched green beans and half of the fried onions, making sure everything is well coated with the creamy sauce. Transfer the mixture to a 9×13 inch baking dish.
Top with the remaining fried onions and the reserved bacon pieces. Bake uncovered for 25-30 minutes until bubbly and the top is golden brown.
Allow to cool for 5-10 minutes before serving.

FAQs
Can I make this ahead of time?
Absolutely! You can prepare the casserole up to the point of baking, then cover and refrigerate for up to 24 hours.
When ready to serve, add the topping of fried onions and reserved bacon, then bake. You may need to add 5-10 minutes to the baking time if cooking from cold.
Can I use canned green beans instead of fresh?
You can, but fresh beans provide the best texture. If using canned, drain them well and skip the blanching step. Frozen green beans are actually a better substitute than canned – just thaw and drain them well.
Is there a lighter version of this recipe?
To lighten it up, use turkey bacon, low-fat milk instead of cream, and reduce the amount of fried onions. The flavor won’t be quite as rich, but it will still be delicious!
How do I keep the fried onions from burning?
If you notice the onions browning too quickly, loosely cover the dish with foil for part of the baking time, removing it for the last 5-10 minutes to crisp up the top.
Can I add other vegetables to this casserole?
Absolutely! Sliced water chestnuts add nice crunch, and roasted red peppers bring color and sweetness.
Just make sure any additional vegetables are well-drained to avoid a watery casserole.
This bacon-infused green bean casserole proves that sometimes, the smallest tweak to a classic recipe can create something truly extraordinary.
The smoky bacon complements the creamy sauce and tender green beans perfectly, while the crispy fried onions provide that signature crunch we all love. It’s comfort food elevated, without straying too far from what makes the original so beloved.
Whether you’re serving it alongside a holiday turkey or as a side dish for a family dinner, this recipe bridges the gap between tradition and innovation.
So go ahead, be the hero who brought bacon to the green bean casserole party – your taste buds (and your grateful guests) will thank you!
