Here’s a modern spin that makes the very best green bean casserole! It’s made from scratch with fresh green beans, mushrooms, and crunchy potato chips.


  • 2 pounds green beans*
  • 2 tablespoons olive oil
  • 8 ounces baby bella mushrooms
  • 1 garlic clove
  • 1 large shallot
  • 1/2 cup heavy cream
  • 1 teaspoon ground dried thyme
  • 1/2 teaspoon dried sage
  • 1 teaspoon kosher salt, plus more to taste
  • Fresh ground black pepper
  • 1/4 cup grated Parmesan cheese
  • 1/2 cup gourmet potato chips, sour cream and onion flavor**


  1. Finely chop the mushrooms. Mince the shallot and garlic. Trim the green beans and cut in half.
  2. In large skillet, heat 1/4 cup water over medium high heat. When simmering, add the green beans and cover. Cook the green beans for 7 to 9 minutes until green and tender, stirring once or twice. Remove the beans from the skillet to a bowl. 
  3. In the same skillet, heat the olive oil over medium high heat. Add the shallot and mushrooms and cook, stirring, 4 to 5 minutes until lightly browned.
  4. Reduce heat to medium low and add the garlic. Cook for 1 minute until fragrant. Add the heavy cream and spices and stir until combined. Add the green beans back to the skillet and cook 1 minute. Add the kosher salt and fresh ground pepper. 
  5. Transfer to a serving dish (9 x 9 or medium casserole dish). Top with grated Parmesan and broken chips. (If making in advance, add the topping immediately before serving so that it stays crunchy.)


*This quantity makes enough for a 9 x 9 size baking dish or casserole dish equivalent. If you’d like a larger amount for Thanksgiving or to feed a huge crowd, you can double and fit into a 9 x 13 size baking dish.

**Of course if you must, feel free to substitute the traditional french fried onions! We won’t judge.
