Make-Ahead Fresh Green Bean Casserole (OAMC)

"Caramelized green beans and convenient. I use disposable tins for simple clean up. I was curious about the technique used-raw green beans with sauce, frozen, and later baked with no defrosting.  Skeptical that this recipe would work well for a meal revolving around a turkey in the oven meal, but it worked perfectly with our grilled turkey.I portioned ours out into small disposable tins. Did not have enough sauce to submerge the beans but made sure top of beans were sealed with sauce. Hubby raved about this because sauce caramelized not that canned soup taste. Keeps in freezer up to two months.  Originally from Cooks Country  November 2008 and Kitchen Parade  2008."

  • SAUCE:  In a large pot or Dutch oven, melt the butter on medium heat til melted, add the mushrooms, salt and pepper and cook for about 8 minutes, stirring often, until the mushrooms are cooked and the mushroom liquid has evaporated.
  • Add the garlic and thyme and cook for about a minute. .
  • Sprinkle the mushrooms with flour and stir in as best you can. A tablespoon at a time, stir in the chicken stock, letting each tablespoon become absorbed before adding another. (This will take several minutes, be patient or you’ll risk a lumpy mess.).
  • Stir in the wine and cream, bring to a boil, reduce heat and simmer,  stirring occasionally, until the sauce is thickened, about 15 minutes, stir in the sherry. .
  • Taste the sauce and add salt and pepper, if needed. (It should be slightly salty and slightly peppery since the beans themselves are unseasoned.).
  • BEANS While the sauce cooks, toss the RAW beans and cornstarch well, transfer to 9x13 dish lined with foil and sprayed or smaller tins.
  • Pour hot mushroom sauce over top. Gently press beans into the sauce so that all the beans are submerged. Cool completely. Cover with plastic wrap, making sure there’s no air between the beans and the plastic. Wrap with foil. Freeze. Do NOT thaw before baking.
  • TOPPING No more than a day before, mix the panko, butter, salt and pepper in a skillet. On medium heat, let the crumbs brown, stirring often, being careful not to burn. Stir in the fried onions.
  • BAKING Preheat oven to 400°F IMPORTANT: remove plastic wrap from casserole, then replace the foil. Bake for 30 minutes, stir, leave the foil off and bake for another 45 to 50 minutes. (Mine are done in 75 minutes but that might be b/c container is small--original recipe says total of 90 minutes.) Spread topping over the casserole, bake for another 10 minutes until golden.
