  • 1 large onion, diced
  • 1 1/2 cups sliced mushrooms
  • 1/3 cup butter
  • 1 teaspoon chicken base
  • 1 tablespoon minced garlic
  • Pepper to taste
  • 1/4 cup nutritional yeast (optional)
  • 1/2 teaspoon ground sage
  • 1/2 teaspoon thyme
  • 1/3 cup heavy whipping cream
  • 3 cups diced cooked turkey
  • 1/2 cup grated parmesan cheese, divided
  • 3/4 cup grated mozzarella cheese
  • 1/2 cup chopped fresh parsley (optional)


  1. Preheat oven to 350°F (175°C).
  2. Melt butter in a skillet over medium heat. Add onion and mushrooms, cook for 20-40 minutes until softened and caramelized (optional, for deeper flavor).
  3. Add sage, garlic, thyme, and pepper. Cook for 1 minute.
  4. Stir in cream and nutritional yeast (if using). Bring to a simmer and cook for 5-10 minutes, until slightly thickened.
  5. Remove from heat and stir in turkey, 1/4 cup parmesan cheese, and parsley (if using).
  6. If using a non-oven-safe skillet, transfer the mixture to an 8×8 inch baking dish.
  7. Top with remaining parmesan cheese and mozzarella cheese.
  8. Bake for 12-15 minutes, until bubbly and golden brown.
  9. Garnish with additional parsley (optional) and serve immediately.


  • Feel free to use any type of cooked turkey, such as leftover roast turkey, ground turkey, or turkey sausage.
  • If you don’t have chicken base, you can substitute it with chicken broth or water.
  • For a richer flavor, you can use full-fat cream cheese instead of heavy whipping cream.
  • Add your favorite chopped vegetables, like broccoli, spinach, or bell peppers, for extra flavor and nutrients.
  • Store leftovers in an airtight container in the refrigerator for up to 3 days.

Calories 344 kcal


  • 1 large onion diced
  • 1 1/2 cups mushrooms sliced
  • 1/3 cup butter
  • 1 teaspoon chicken base
  • 1 tablespoon minced garlic
  • Freshly ground pepper to taste
  • 1/4 cup nutritional yeast
  • 1/2 teaspoon ground sage
  • 1/2 teaspoon thyme
  • 1/3 cup heavy whipping cream
  • 3 cups turkey diced
  • 1/2 cup Parmesan cheese grated and divided
  • 3/4 cup mozzarella cheese grated
  • 1/2 cup fresh parsley chopped (optional)


  • Preheat your oven to 350°F (175°C).
  • In a cast iron skillet, melt butter over medium heat. Add the diced onion, sliced mushrooms, and chicken base. Sauté for about 20 minutes, until the onion and mushrooms start to caramelize. For deeper caramelization, you can extend this to up to 40 minutes.
  • Stir in the minced garlic, sage, thyme, and pepper. Cook for an additional minute.
  • Add the heavy whipping cream and nutritional yeast (if using). Continue stirring occasionally on medium heat until the mixture thickens, which should take about 5-10 minutes.
  • Fold in the diced turkey, optional parsley, and 1/4 cup of the grated Parmesan cheese. Remove from heat.
  • If your skillet is not oven-safe, transfer the mixture to an oven-safe baking dish (8" x 8" should be sufficient).
  • Top with the remaining Parmesan and the mozzarella cheese.
  • Bake in the preheated oven for 12-15 minutes, or until the dish is bubbly and slightly golden on top. Garnish with additional parsley, if desired, before serving.
