Creating Ham Steaks in Madeira Sauce is simple and rewarding. Follow these steps to prepare this delightful dish:

1. Prepare the Ham Steaks: Pat the ham steaks dry with paper towels and season both sides with salt and black pepper.
2. Heat the Oil: In a large skillet, heat the olive oil over medium-high heat.
3. Sear the Ham Steaks: Add the ham steaks to the skillet and cook for about 3-4 minutes on each side, or until they are golden brown. Remove the steaks from the skillet and set them aside.
4. Sauté the Onion and Garlic: In the same skillet, add the butter. Once melted, add the chopped onion and sauté until translucent, about 3 minutes. Add the minced garlic and sauté for an additional minute.
5. Add the Madeira Wine: Pour in the Madeira wine, scraping the bottom of the skillet to deglaze it. Bring the mixture to a simmer.
6. Incorporate Sweetness and Flavor: Stir in the brown sugar and Dijon mustard, mixing well until the sugar is dissolved.
7. Return the Ham Steaks: Place the seared ham steaks back into the skillet, ensuring they are coated in the sauce. Let them simmer for about 5 minutes, allowing the flavors to meld and the sauce to thicken slightly.
8. Adjust Seasoning: Taste the sauce and adjust the seasoning with more salt or pepper as needed.
9. Garnish: Once cooked through, remove from heat and sprinkle with freshly chopped parsley for a touch of color.
10. Serve: Transfer the ham steaks to a serving platter and drizzle with the Madeira sauce from the skillet.
