Ingredients

• 4 cups fresh green beans (stems removed and chopped into smaller pieces)
• Onion straws (suggest making your own)
• Cream of Mushroom Soup
• 4 tablespoons butter
• 1 large onion (minced)
• 2 cloves of garlic
• ½ lb mushrooms (thinly sliced, use a variety for depth of flavor)
• ¼ cup white wine
• 1 cup chicken broth
• 1 teaspoon dried thyme
• ½ teaspoon black pepper
• ¼ cup heavy whipping cream
• 2 tablespoons flour
• 1 teaspoon salt

Instructions

1. Step 1: Make your air fryer onion straws ahead of time. When ready to make the casserole, preheat your oven to 350℉.
2. Step 2: Trim and chop the green beans into bite-sized pieces. Boil them in water for 5-6 minutes to slightly tenderize, then set aside. Skip this step if using canned green beans. Place the green beans in a casserole dish.
3. Step 3: Melt the butter in a pan over medium heat. Cook the minced onion until translucent, about 5 minutes. Add garlic and cook for an additional 30 seconds.
4. Step 4: Add the mushrooms, white wine, chicken broth, dried thyme, and black pepper. Bring to a boil and cook for 5 minutes.
5. Step 5: Whisk together heavy cream, flour, and salt. Add this mixture to the pan and simmer for another minute until thickened.
6. Step 6: Pour the mushroom sauce over the green beans and stir gently to combine.
7. Step 7: Bake the uncovered casserole in the preheated oven for 30 minutes.
8. Step 8: Top the casserole with onion straws and bake for an additional 5 minutes until onions are golden and crispy. Serve hot.

Tips & Variations

• Use a mix of cremini, shiitake, and baby bella mushrooms for a richer flavor and varied texture.
• If using canned green beans, be sure to drain them well before adding to avoid excess liquid.
• Prepare the casserole a day ahead but add the onion topping just before baking to keep it crispy.

Storage

Store leftover casserole in the fridge for 2-3 days. Reheat portions in the microwave. Note that the onion straws will lose their crispiness but the dish remains delicious.

FAQs

Can I skip boiling the green beans?

If you are using fresh green beans, boiling them briefly helps soften them without overcooking. If using canned or home-canned green beans, you can skip boiling since they are already softened.

How do I make homemade onion straws?

To make onion straws, thinly slice onions, coat them in seasoned flour or batter, and cook them in an air fryer or deep fryer until golden and crispy.

Green Beans

• 4 cups fresh green beans, stems removed and chopped into bite-sized pieces

Mushroom Sauce

• 4 tablespoons butter
• 1 large onion, minced
• 2 cloves garlic, minced
• ½ lb mushrooms (cremini, shiitake, baby bella), thinly sliced
• ¼ cup white wine
• 1 cup chicken broth
• 1 teaspoon dried thyme
• ½ teaspoon black pepper
• ¼ cup heavy whipping cream
• 2 tablespoons flour
• 1 teaspoon salt

Topping

• Onion straws (preferably homemade and crispy)

Instructions

1. Prepare Onion Straws: Make your air fryer onion straws ahead of time to ensure they are crispy and ready for topping the casserole.
2. Preheat Oven: Preheat your oven to 350°F (175°C) to get it ready for baking the casserole.
3. Cook Green Beans: Trim and chop the fresh green beans, then boil them in water for 5-6 minutes until just tender. Drain and place them in your casserole dish. If using canned green beans, drain them first and skip this step.
4. Sauté Aromatics: Melt 4 tablespoons of butter over medium heat in a skillet. Add the minced onion and cook until translucent, about 5 minutes. Add minced garlic and sauté for an additional 30 seconds to release its aroma.
5. Add Mushrooms and Liquids: Add the sliced mushrooms, white wine, chicken broth, dried thyme, and black pepper to the skillet. Bring to a boil and let it cook for about 5 minutes to reduce and concentrate the flavors.
6. Thicken Sauce: In a separate bowl, whisk together the heavy cream, flour, and salt until smooth. Stir this mixture into the skillet and let it simmer for about a minute until the sauce thickens. This step is crucial to prevent the casserole from becoming soupy.
7. Combine Sauce and Beans: Pour the thickened mushroom sauce over the green beans in the casserole dish and gently stir to combine evenly.
8. Bake Casserole: Bake the uncovered casserole in the preheated oven at 350°F for 30 minutes, allowing the flavors to meld and the sauce to set.
9. Add Onion Straw Topping: Sprinkle the crispy onion straws evenly on top of the casserole. Return to the oven and bake for an additional 5 minutes until the onions turn golden and crispy.
10. Serve: Remove from the oven and serve the casserole hot as a delicious side dish.

Notes

• If using canned green beans, be sure to drain them well before adding to the casserole.
• This casserole can be prepared a day in advance, but leave the onion topping off until just before baking.
• For deeper flavor, combine different mushroom varieties such as cremini, shiitake, and baby bella.
• Store leftover casserole in the refrigerator for 2-3 days. Reheat portions in the microwave; however, the onion straws will lose their crispiness but remain tasty.
