Ingredients

  • 3 ½ cups fresh green beans Partially cooked, see notes
  • 8 oz. cremini mushrooms cleaned and sliced.
  • 1 cup heavy cream
  • cup chicken broth
  • 1 tbsp. garlic minced
  • 1 small onion petite diced
  • 1 tsp. salt
  • 1 tsp. black pepper fresh cracked
  • 2 tbsps. all purpose flour
  • 3 tbsps. butter or olive oil
  • 1 tsp. fresh rosemary
  • 2 cups French's Crispy Fried Onions or more if you like

Instructions

  • Preheat oven to 400 F.
  • Trim the green beans and cut into 2-3 inch long pieces.
  • Bring a pot of water to boil. Once it starts boiling, drop in the beans and cook for 3 minutes. If you like them softer, you can cook for an extra minute. Drain and set aside.
  • Melt the butter and pan sear the onions until they are partially caramelized on high heat. Add in the garlic and sauté for another 30 second.
  • Add in the mushrooms and sauté for 2-3 minutes. Add in the flour and mix well.
  • Pour in the chicken broth, heavy cream, salt and pepper. Mix well to avoid any clumps.
  • Lower the heat to medium and let the sauce simmer to thicken up. Do not boil. The sauce should just simmer.
  • Once the sauce thickens up, add in the green beans. Mix together to coat well with the sauce and top with the crispy onions.
  • Bake for 10-15 minutes until bubbly and then remove from the oven.
  • Let it cool for a couple of minutes before serving.

Notes

  • Use a preheated oven.
  • I recommend using fresh green beans for optimal crispness.
  • If you want vibrant and super crisp green beans, immediately put the beans in some ice water after boiling.
  • For crunchy beans boil for around 3 mins, if you want them softer, allow to boil for a few more mins.
  • For a kick of heat, try adding some diced jalapeno!
  • Make it cheesy. Stir in some gouda for a cheesy twist.
  • Serve warm and garnish with fresh parsley, if you like.
  • Using store bought fried onions will save you a lot of time. Their crunch also lasts longer than homemade ones.
