Equipment
- stock pot
- saute pan
- 9x9 inch (23x23 cm) baking dish
Ingredients
- 4 tablespoons unsalted butter divided
- 8 ounces white mushrooms cleaned and finely chopped
- ¾ cup yellow onion finely diced (about 1 small onion)
- 4 cloves garlic minced
- 1 teaspoon Morton kosher salt
- ¼ teaspoon finely ground black pepper
- 4 tablespoons all purpose flour
- 1 ½ cups chicken stock
- 1 ½ cups heavy cream
- 1 pound extra fine frozen green beans thawed
- 1 cup crispy fried onions
- 1 cup panko bread crumbs
Instructions
- Heat oven to 400°F (205°C).
- Melt 2 tablespoons (28 grams) butter in a saute pan over medium heat. Add mushrooms and onions and cook, stirring occasionally, until they are cooked down, about 8–10 minutes. Add garlic, salt, and pepper, and cook for an additional minute. Turn heat to medium low. Stir in flour, and cook for 1–2 minutes.
- Stir in chicken stock and heavy cream. Allow the mixture to cook, stirring often, until a thick sauce forms, about 10–12 minutes. Stir in green beans, and cook until warmed.
- Transfer the green bean mixture to a 9 x 9 inch (23 x 23 cm) baking dish.
- Melt the remaining 2 tablespoons (28 grams) butter in a mixing bowl. Add crispy fried onions and panko to melted butter, and stir to combine. Top green beans with the onion mixture.
- Cook uncovered for 8–12 minutes until golden brown on top. Serve immediately, or cover with aluminum foil to keep warm.
Notes
Make Ahead: Make the green beans (without the topping), and store in the fridge for up to 72 hours (3 days). When you are ready to bake, take it straight from the fridge, and cover with aluminum foil. Bake at 400°F (205°C) for 10–12 minutes. Remove the foil, add the topping, and bake uncovered for an additional 8–12 minutes.
Leftovers: Store leftovers in an airtight container for up to 6 days. Reheat in the microwave or on the stovetop until heated through.
