Instructions:

1. Prepare the Marinade:
- In a medium bowl, combine the red wine, minced garlic, rosemary, and olive oil. Mix well to combine.
2. Marinate the Steak:
- Place the beef fillets in a shallow dish or resealable plastic bag.
- Pour the marinade over the fillets, ensuring they are well coated.
- Cover the dish or seal the bag and refrigerate for at least 2 hours, preferably overnight, to allow the flavors to penetrate the meat.
3. Prepare the Creamy Mash:
- Place the peeled and chunked potatoes in a large pot and cover with cold water.
- Bring to a boil over medium-high heat, then reduce to a simmer. Cook until the potatoes are tender, about 15-20 minutes.
- Drain the potatoes and return them to the pot.
- Add the buttermilk and butter to the potatoes.
- Mash the potatoes until smooth and creamy. Season with salt and pepper to taste. Keep warm until ready to serve.
4. Cook the Steak:
- Preheat your grill or a large skillet over medium-high heat.
- Remove the beef fillets from the marinade, allowing any excess to drip off.
- Pat the fillets dry with paper towels. This helps achieve a good sear.
- Lightly spray the cooking spray oil on the grill or skillet to prevent sticking.
- Place the fillets on the grill or skillet and cook for 4-5 minutes per side for medium-rare, or until they reach your desired level of doneness.
- Remove the steaks from the heat and allow them to rest for a few minutes to let the juices redistribute.
5. Serve:
- Place a generous spoonful of the creamy mashed potatoes on each plate.
- Top with a perfectly cooked steak fillet.

Classic red wine-marinated steak with creamy mash FAQ:

What is the ideal marinating time for the steak?

For best results, marinate the steak for at least 2 hours, but preferably overnight. This allows the flavors to properly penetrate the meat, enhancing its taste.

How do I know when the steak is cooked to medium-rare?

Cook the steak for 4-5 minutes on each side over medium-high heat. An internal temperature of 135°F (57°C) indicates medium-rare doneness. Use a meat thermometer for accuracy.

Can I substitute the red wine with something else?

Yes, if you prefer not to use red wine, you can substitute it with beef broth or a mixture of grape juice and vinegar for a similar depth of flavor.

How should I store leftover steak and mashed potatoes?

Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat the steak gently to avoid overcooking and the mash in the microwave or on the stove with a splash of milk.

What type of potatoes is best for creamy mashed potatoes?

Russet or Yukon Gold potatoes are ideal for creamy mashed potatoes due to their starchy texture, which yields a fluffy and smooth consistency when mashed.

Tips:

- Marinate the steak for at least 2 hours or overnight for the best flavor penetration.

- Use a meat thermometer to ensure your steak reaches the desired level of doneness.

- For extra smooth mashed potatoes, use a potato ricer or a food mill.

- Let the cooked steaks rest for a few minutes before slicing to retain juices and ensure a juicy, tender bite.
