- 2 tablespoons unsalted butter, softened
- 1⁄4 teaspoon salt
- 1⁄8 teaspoon pepper
- 3 cups French-fried onions
-
Beans
- 2 tablespoons salt
- 1 teaspoon salt
- 2 lbs fresh green beans, ends trimmed, cut on the diagonal into 2 inch pieces
- 1⁄2 ounce dried porcini mushrooms, rinsed well
- 6 tablespoons unsalted butter
- 1 onion, minced
- 12 ounces white button mushrooms, cut into 1/4 inch slices
- 12 ounces cremini mushrooms, cut into 1/4 inch slices
- 2 tablespoons fresh thyme, minced

- 3 garlic cloves, minced
- 2 tablespoons all-purpose flour
- 1 cup low sodium chicken broth
- 2 cups heavy cream
directions
- For the topping: pulse the bread, softened butter, salt and pepper in a food processor until the mixture resembles coarse crumbs, about ten 1-second pulses. Transfer to a large bowl and toss with the onions; set aside.
- For the beans: Adjust an oven rack to the middle position and heat the oven to 375 degrees. Bring 4 qt water to a boil in a large pot. Add 2 tbsp salt and the beans. Cook until bright green and slightly crunchy, 4 to 5 minutes. Drain the beans and plunge immediately into a large bowl filled with ice water to stop cooking. Spread the beans out on a paper towel-lined baking sheet to drain.
- Meanwhile, cover the dried porcini mushrooms with 1/2 cup hot tap water in a small microwave-safe bowl; cover with plastic wrap, cut several steam vents with a paring knife, and microwave on high power for 30 seconds. Let stand until the mushrooms soften, about 5 minutes. Lift the mushrooms from the liquid with a fork and mince using a chef's knife (you should have about 2 tablespoons). Pour the liquid through a paper towel-lined sieve and reserve.
- Melt the butter in a large nonstick skillet over medium-high heat until the foaming subsides, about 1 minute. Add the onion, button and cremini mushrooms and cook until the mushrooms release their moisture, about 2 minutes. Add the porcini mushrooms along with their strained soaking liquid, thyme, 1 tsp salt and pepper; cook until all the mushrooms are tender and the liquid has reduced to 2 tablespoons, about 5 minutes. Add the garlic and saute until aromatic, about 30 seconds. Add the flour and cook for about 1 minute. Stir in the broth and reduce the heat to medium. Stir in the cream and simmer gently until the sauce has the consistency of a dense soup, about 15 minutes.
- Arrange the beans in a 3-quart gratin dish. Pour the mushroom mixture over the beans and mix to coat the beans evenly. Sprinkle with the breadcrumb mixture and bake until the top is golden brown and the sauce is bubbling around the edges, about 15 minutes. Serve immediately.

<p>I love to cook, bake and eat. Sometimes I'm more in the mood to cook than to eat (or clean up the mess!) I love to think of new ways to cook everyday foods and spice things up. I love to try new foods, I'll try most anything once. </p>
