Ingredients

  1. Kosher salt
  2. 1 1/2 pounds green beans, trimmed and halved crosswise
  3. 2 tablespoons unsalted butter
  4. 1 medium onion, diced
  5. 1/2 pound button mushrooms, sliced
  6. 2 tablespoons all-purpose flour
  7. 2 cups low-sodium chicken broth
  8. 1/2 cup half-and-half
  9. Freshly ground black pepper
  10. 1 1/2 cups prepared fried onions

Instructions

  1. Bring a large pot of salted water to a boil. Add the green beans, and cook until bright green and crisp-tender, about 10 minutes. Drain and shake off any excess moisture; set aside.
  2. Melt the butter in a medium pot over medium heat. Add the onions, and cook, stirring, until soft, about 8 minutes. Add the mushrooms and a pinch of salt, and continue to cook, stirring, until they are soft and most of their liquid has evaporated, about 10 minutes. Sprinkle the flour over the vegetables, and stir until all the flour has been absorbed, about 1 minute. Add the chicken broth, half-and-half, 3/4 teaspoon salt and several grinds of pepper. Bring to a boil, then reduce to a simmer and cook, stirring, until the sauce thickens and coats the back of a spoon, about 5 minutes. Remove the pot from the heat, add the green beans and stir to coat in the sauce. Transfer the mixture to a 3-quart baking dish.
  3. Let the casserole cool to room temperature. Wrap well with plastic wrap and foil, label and date, then freeze for up to 2 weeks.
  4. To serve, preheat the oven to 350 degrees F. Discard the plastic wrap and foil from the frozen casserole. Cover with new foil, and bake until warmed through, about 45 minutes. Uncover, and top with the fried onions. Continue to bake until the casserole is hot and bubbly and the onions have crisped slightly, about 20 minutes more.

This would have been really good if I hadn’t ever frozen it and reheated. Made fresh it’s delicious, but after freezing and reheating, the sauce became compromised and the green beans very watery. It didn’t get hot quickly enough in the middle after reheating as instructed, and required twice the amount of time in oven to become hot throughout. I ended up burning my fried onions because of the additional needed time. They were actually fried shallots I had prepared carefully myself! Not French’s 😉 Alas. I would try this again, but only on the day of or night before.

Best recipe I have tried. This is the one. I didn’t make it ahead, but instructions are there if you don’t want to make it ahead. I followed exactly, except I mixed a few fried onions in the bean mixture and topped with the 1 12 cups . Delicious.

Made the day before serving, so refrigerated instead of freezing and it turned out great.
Jeffrey Robertson
Doesn’t freezing it make the greenbeans too soft or mushy??? I’m making it but just curious
Peter Montes

Does anyone know if this can be made a day ahead of time and not frozen?

So yummy! Followed all steps except did not add mushrooms. Will definitely make again.
Susan Jones
Came out perfectly. The fresh mushrooms had great flavor.

French’s Crispy Fried Onions are the best – don’t bother substituting other brands (truly). This dish is delicious & fairly easy to put together with no fuss like other recipes.
