Bacon Green Bean Casserole

nonstick cooking spray

salt(for blanching)

1 lb green beans(trimmed)

8 ounces cremini mushrooms

½ medium yellow onion

2 cloves garlic

4 slices bacon

1 tsp dried thyme

3 tablespoons all purpose flour

⅔ cup chicken broth

1 ⅓ cups half and half

½ tsp salt(for casserole)

¼ tsp black pepper

½ cup french fried onions

Instructions

Preheat the oven to 400°F.

Spray an 8- or 9-inch square baking dish with nonstick cooking spray. Set aside.

Bring a large pot of salted water to a boil.

Cut the green beans into 1 1/2-inch pieces. Slice the mushrooms, finely chop the onion, and mince the garlic.

Once the water is boiling, add the green beans. Blanch until they are bright green, about 3 minutes. Drain in a colander and rinse with cold water.

Set a large pot over medium-high heat and add the bacon. Cook, flipping once, until browned and crispy. Transfer bacon to a paper towel-lined plate to drain. Do not discard the fat from the pot.

Add the mushrooms and chopped onion to the bacon drippings. Saute until mushrooms are browned and shrunken and onion is soft, 6-7 minutes. Add the garlic and thyme and cook until fragrant, about 30 seconds.

Sprinkle the flour over mushroom mix and stir with a spatula to coat. Slowly pour the chicken broth into the pot, whisking to dissolve flour. Pour in the half-and-half, and season with the salt and black pepper.

Cook the sauce, whisking constantly, until it begins to bubble and thicken. Reduce heat to medium-low and allow sauce to simmer, whisking occasionally, until it is reduced by about a third, 5-7 minutes.

Crumble or chop the bacon into 1/4-inch pieces. Add the green beans and half the bacon to the pot, and stir to coat with the sauce. Pour the green bean mixture into the prepared baking dish.

Bake the casserole on middle rack of oven for 15 minutes.

Open the oven and sprinkle the french-fried onions and reserved bacon in an even layer over the top. Continue baking until casserole is bubbling at the edges, 5-10 minutes.

Check to see that casserole is done. Remove from oven or add time as needed.

Allow casserole to rest for 10-15 minutes before serving.

Tips & Tricks (5)

Render Bacon Perfectly 🥓
Cook bacon low and slow (medium heat) until crispy, then reserve the fat for sautéing mushrooms and onions—this infuses the casserole with deep, savory bacon flavor that store-bought oil cannot match.
Toast Flour for Silky Sauce 🌾
Create a proper roux by cooking the flour in bacon fat for 1-2 minutes before adding broth—this eliminates raw flour taste and creates a velvety, lump-free sauce that coats the vegetables beautifully.
Blanch Green Beans First 💚
Pre-cook green beans in salted boiling water for 3-4 minutes, then shock in ice water—this brightens their color, ensures even cooking, and prevents them from becoming mushy in the oven.
Add Fried Onions at the End ✨
Reserve half the french fried onions to sprinkle on top during the last 5 minutes of baking—this keeps them crispy and prevents them from absorbing moisture and becoming soggy.
Season in Layers 🧅
Season mushrooms and onions when sautéing, then taste and adjust salt again before baking—this builds complex flavor throughout rather than relying on one final seasoning that may not distribute evenly.
