Ingredients
  

Main Ingredients
  • 2 pounds Green beans, fresh, frozen, or canned Fresh (trimmed and boiled), frozen (thawed), or canned (drained)
  • 8-12 ounces Mushrooms, sliced
  • 3 tablespoons Butter
  • 0.5 medium onion Onion, finely chopped
  • 2 cloves Garlic, minced
  • 3 tablespoons Flour
  • 1 cup Broth, chicken or veggie
  • 0.75 cup Milk or half and half
  • to taste Salt and pepper
  • 1 teaspoon Soy sauce or Worcestershire sauce Optional but adds depth
  • 1.5 cups French fried onions For mixing in and topping

Method
 

Preparation
  1. Prep the green beans. If using fresh, trim and boil in salted water until just tender, then drain. Frozen green beans just need a quick thaw and drain. Canned beans need to be drained and rinsed if they taste too salty.
  2. Make the quick mushroom sauce. In a large skillet, melt butter. Add onion and mushrooms, cooking until the mushrooms release their liquid and start to brown. Add garlic for the last 30 seconds of cooking.
  3. Thicken the sauce. Sprinkle flour over the mushrooms and stir for about a minute. Gradually pour in the broth, then the milk, stirring until the mixture turns creamy. Season with salt, pepper, and add a splash of soy sauce or Worcestershire if using.
  4. Mix and bake. Preheat the oven to 350°F. Stir the green beans into the sauce. Optionally, mix in a handful of fried onions for added crunch. Pour the mixture into a baking dish and bake for about 20 minutes.
  5. Add the topping. Remove from the oven, add the remaining fried onions on top, then return to bake for an additional 5 to 10 minutes until the top is golden.

Notes

Drain your beans well to avoid a watery casserole. Brown the mushrooms for a richer flavor. Avoid overbaking to retain moisture. If you want crispy leftovers, add fresh fried onions after reheating.
