Ingredients:
- 1.5 lbs fresh green beans, trimmed and halved
- 1 tsp sea salt
- 8 oz cremini mushrooms, finely chopped
- 3 tbsp unsalted butter
- 3 tbsp all-purpose flour
- 1.5 cups whole milk, room temperature
- 0.5 cup heavy cream
- 2 cloves garlic, minced
- 0.25 tsp ground nutmeg
- Salt and cracked black pepper to taste
- 1.5 cups crispy fried onions
- 0.25 cup grated Parmesan cheese
Instructions:
- Prep the beans. Bring a large pot of salted water to a rolling boil. Drop in your 1.5 lbs of trimmed green beans and cook for 5 minutes. Note: This softens the outer fiber without making them mushy.
- The Ice Bath. Immediately drain the beans and plunge them into a bowl of ice water. Cook 5 mins until tender crisp. This preserves that bright green color we all love.
- Sauté the mushrooms. Melt 3 tbsp of unsalted butter in your skillet over medium heat. Add the 8 oz of chopped cremini mushrooms. Sauté 8 minutes until moisture evaporates and they turn deep brown.
- Fragrant additions. Stir in your 2 cloves of minced garlic and cook for 30 seconds until the aroma fills the room.
- Build the roux. Sprinkle 3 tbsp of all purpose flour over the mushrooms. Whisk for 1-2 minutes until the flour smells toasted.
- Create the sauce. Slowly pour in the 1.5 cups of milk and 0.5 cup of heavy cream. Whisk constantly until the sauce is thick and velvety.
- Season and fold. Stir in the nutmeg, salt, pepper, blanched beans, and half of the fried onions. Note: The nutmeg is the secret to that hidden depth of flavor.
- Initial bake. Preheat your oven to 375°F (190°C). Slide the skillet in and bake for 20 minutes until bubbling.
- The final crunch. Sprinkle the remaining onions and 0.25 cup of Parmesan cheese over the top. Bake 10 mins until the topping is golden and shattering.
- Rest. Let it sit for 5 minutes before serving to let the sauce set. For those looking for a slightly different take on a veggie filled side, my [Sautéed green beans](https://easychefideas.com/recipes/sauteed-green-beans-with-bacon-garlic/) use a similar blanching technique but focus on a smoky bacon finish. It’s a great comparison if you want to see how different fats change the profile of the bean.
