Step-by-Step Instructions
- In a large skillet, add olive oil and butter over medium-high heat. Allow the fats to melt and heat until shimmering, about 2–3 minutes.
- Add sliced mushrooms and chopped onion to the skillet. Sauté for 10–12 minutes, stirring occasionally, until the mushrooms are browned.
- Lower the heat and stir in minced garlic and Dijon mustard. Cook for an additional 30 seconds until fragrant.
- Pour in dry Marsala wine and bring to a gentle bubble. Simmer for about 30 seconds to 1 minute.
- Reduce the heat to low and gently incorporate heavy cream along with the cornstarch slurry. Cook about 5 minutes until thickened.
- Season with salt and pepper to taste. Add fresh parsley if desired.
