Ingredients
4 slices white bread, torn into quarters
2 tablespoons unsalted butter, softened
1/4 teaspoon salt
1/8 teaspoon ground black pepper
6 oz canned fried onions
2 tablespoons salt (for blanching water)
2 pounds green beans, trimmed and halved
3 tablespoons unsalted butter
1 pound white button mushrooms, broken into pieces
3 cloves garlic, minced
3/4 teaspoon salt
1/8 teaspoon ground black pepper
3 tablespoons all-purpose flour
1 1/2 cups chicken broth
1 1/2 cups heavy cream
Instructions
Step 1: Prepare the Topping
Pulse the bread, butter, salt, and pepper in a food processor until it forms coarse, buttery crumbs. Transfer this to a bowl and gently toss with the fried onions, then set aside for the final step.
Step 2: Blanch the Beans
Boil 4 quarts of water with 2 tablespoons of salt. Add the fresh beans and cook for 6 minutes until bright and tender. Quickly drain and drop into an ice-water bath to lock in the color. Spread on paper towels to dry.
Step 3: Create the Mushroom Sauce
In the same pot, melt butter and cook mushrooms, garlic, salt, and pepper until the mushrooms are dry and golden. Sprinkle with flour and cook for 1 minute. Gradually whisk in the chicken broth and heavy cream, simmering until the sauce is thickened and reduced, about 12 minutes.
Step 4: Assemble and Bake
Stir the blanched beans into the sauce until coated. Spread into a 9×13 baking dish, sprinkle with your prepared crumb topping, and bake at 425 degrees F for 15 minutes until bubbly and golden.
Pro Tips
- Always dry your green beans thoroughly on paper towels so the sauce doesn’t become watery.
- Don’t rush the mushroom cooking process; browning them adds massive depth to the final sauce.
- If you want extra color, place the casserole under the broiler for the last 60 seconds of baking.
- Keep the topping separate until right before baking to ensure the onions stay as crisp as possible.
Notes
Ensure the green beans are thoroughly drained after blanching to avoid a watery sauce. You can substitute vegetable broth for the chicken broth if you prefer a vegetarian version. Store leftovers in an airtight container in the refrigerator for up to 3 days.
