Notes

  • Cremini or white mushrooms work best for this recipe.
  • You can substitute Swiss cheese with mozzarella, provolone, Monterey Jack, or cheddar.
  • For a lower-carb version, replace pasta with cauliflower or extra mushrooms.
  • The casserole can be assembled ahead and refrigerated before baking.
  • Store leftovers in the refrigerator for up to 4 days.
  • Add a splash of broth while reheating to keep the casserole creamy.
