Green bean casserole:

  • 1 pound fresh green beans
  • 2 tbsp butter
  • 1/2 cup onion, chopped (about 1 small onion)
  • 8 ounces baby portabella mushrooms, sliced
  • 2 cloves garlic, minced
  • 3 tbsp white wine
  • 1 tbsp Dijon mustard
  • 4 oz cream cheese (half a block)
  • 1/2 cup chicken broth
  • 1/2 cup cheddar, shredded

Optional toppings:

  • Crumbled cooked bacon or crushed pork rinds


  • Preheat oven to 350 degrees. Grease a casserole dish and set aside for now.
  • Place green beans in a microwave safe dish with a little water. Steam in the microwave for around 4 minutes. You want them to still be crisp tender.
  • Meanwhile, heat butter in a large skillet over medium heat. Add onion and mushrooms. Cook for 5-7 minutes, until both are tender.
  • Add the garlic, white wine and Dijon mustard. Cook for a minute.
  • Stir in cream cheese, chicken stock, and cheddar. Continue cooking over medium heat for another few minutes, stirring frequently, until everything is well combined.
  • Mix with green beans and then pour everything into the casserole dish. Bake at 350 degrees for 20-30 minutes, until everything is hot and bubbly. If desired, add optional topping once you remove from the oven. Enjoy!
