  • 2 Pounds Frozen French Cut Green Beans thawed*
  • 2 Tablespoons Unsalted Butter
  • 2 Cups Mushrooms sliced
  • 1 Yellow Onion chopped
  • 1/2 Teaspoon Kosher Salt
  • 1/4 Teaspoon Pepper
  • 1 1/2 Cup Heavy Cream
  • 1 Teaspoon Xanthan Gum
  • 1/2 Teaspoon Tabasco
  • 1 Teaspoon Thyme fresh
  • 3 Cups Sharp Cheddar Cheese divided
  • Pork Rinds optional


  • Preheat oven to 425 F.
  • Wrap the thawed green beans (2 pounds) in a clean kitchen towel, and allow them to drain in a colander while you prep the rest of the ingredients.
  • Add pork rinds to a large ziplock bag. Close to seal, and hit the bag with a rolling pin to break them into small, bread crumb sized pieces. Set bag aside.
  • Melt butter (2 tablespoons) in a large oven safe skillet.
  • Add sliced mushrooms (2 cups), yellow onions (1 chopped), salt (1/2 teaspoon), and pepper (1/4 teaspoon) and saute over medium heat until onions become translucent (about 10 minutes).
  • Lower the heat to medium-low and stir in heavy cream (1 1/2 cups), Tabasco (1/2 teaspoon), thyme (1 teaspoon) and xanthan gum (1 teaspoon). Bring the combo to a gentle simmer.
  • Cook veggies in simmering cream for 15 minutes, you'll know they're done once the sauce has reduced by half, and it coats the back of a spoon.
  • Meanwhile, gently ring out any additional water from your green beans. You want to remove as much liquid from the green beans as possible, without squishing them.
  • Stir in the green beans and cheddar cheese (1 cup).
  • Taste test to check the seasoning (I usually add an additional 1/2 teaspoon of salt here.)
  • Remove from heat, and sprinkle the top of your pan with cheddar (2 cups) and crushed pork rinds.
  • Bake for 20 minutes, you'll know the casserole is done once the beans are heated through and the cheese starts to bubble. Enjoy!


  • To thaw the green beans, I let them sit in the fridge overnight on a large plate.
