Recipe Information
Ingredients
- 1 lb pork tenderloin
- 8 oz cremini or white mushrooms
- 1 medium onion
- 3 cloves garlic cloves
- 2 tbsp butter
- 1 tbsp olive oil
- 2 tbsp all-purpose flour
- 1.5 cups chicken broth
- 0.5 cups heavy cream
- 0.5 cups shredded Parmesan cheese
- 1 tsp fresh thyme leaves
- 1 tsp salt
- 0.5 tsp ground black pepper
- 0.5 cups breadcrumbs
- 2 tbsp parsley (for garnish)
Instructions
Preheat your oven to 375°F (190°C).
Slice the pork tenderloin into thin medallions and season with 1/2 teaspoon of salt and 1/4 teaspoon of black pepper.
Heat a large skillet over medium-high heat and add olive oil. Sear the pork medallions for 2 minutes per side, until lightly browned. Remove them from the skillet and set aside.
In the same skillet, melt butter over medium heat. Add diced onion and cook until softened, about 4 minutes.
Add minced garlic and cook for an additional 30 seconds, until fragrant.
Slice the mushrooms and add them to the skillet. Cook for 5 minutes until they release their moisture and start to brown.
Sprinkle flour over the mushroom mixture and stir to coat everything evenly. Cook for 1 minute to toast the flour slightly.
Slowly pour in the chicken broth while stirring to avoid lumps. Simmer the sauce for 3-4 minutes until it thickens.
Stir in heavy cream, Parmesan cheese, fresh thyme, and the remaining salt and pepper. Cook for another 2 minutes until the sauce is creamy and smooth. Remove from heat.
In a greased 9x13-inch casserole dish, layer the seared pork medallions across the bottom.
Pour the creamy mushroom sauce evenly over the pork.
Sprinkle breadcrumbs over the top of the casserole for a crispy topping.
Bake in the preheated oven for 25-30 minutes, or until the casserole is bubbly and golden on top.
Garnish with freshly chopped parsley before serving.
