Step-by-Step Instructions

Step 1: Prepare the Steaks

1. Pat the steaks dry with paper towels to ensure a good sear.
2. Season both sides with salt and black pepper.
3. Heat 2 tbsp olive oil in a large skillet over medium-high heat.
4. Add steaks and cook for 3-4 minutes per side for medium-rare (adjust cooking time for desired doneness).
5. Transfer steaks to a plate and cover with foil to rest while you make the sauce.

Step 2: Make the Diane Sauce

1. In the same skillet, melt 2 tbsp butter over medium heat.
2. Add shallots and garlic and sauté for 1-2 minutes until softened and fragrant.
3. Add mushrooms and cook for 4-5 minutes until golden brown.
4. Stir in Dijon mustard and Worcestershire sauce, mixing until well combined.
5. Pour in beef broth and let it simmer for 3-4 minutes to reduce slightly.
6. Lower the heat and add heavy cream, stirring continuously until the sauce thickens and becomes velvety.
7. Add lemon juice and freshly ground black pepper to taste.
8. Stir in chopped parsley for a burst of freshness.

Step 3: Finish the Steaks

1. Return the steaks to the skillet, spooning the sauce over each piece.
2. Simmer for 1-2 minutes to warm through and let the meat absorb some of the sauce.

Step 4: Serve and Garnish

1. Place the steaks on serving plates and generously spoon the Diane sauce over each.
2. Garnish with extra chopped parsley and a squeeze of fresh lemon juice for added brightness.

Serving Suggestions

Tips for the Best Steak Diane

• Choose the Right Cut: Beef tenderloin or filet mignon are the classic choices for this dish.
• Avoid Overcooking: Steak Diane is traditionally served medium-rare; use a meat thermometer for accuracy.
• Sear and Rest: Searing the steak at high heat locks in the juices, while resting ensures tender meat.

How to Store & Reheat

Storing:

• Store leftover steak and sauce in an airtight container in the refrigerator for up to 2 days.

Reheating:

• Reheat in a skillet over low heat, adding a splash of beef broth or cream to revive the sauce.

Frequently Asked Questions

1. Can I use other cuts of steak?
   Yes! Sirloin, ribeye, or strip steak work well, but adjust the cooking time accordingly.
2. How can I make the sauce thicker?
   Let the sauce simmer for a few extra minutes, or whisk in a small amount of cornstarch slurry.
3. Can I make this dairy-free?
   Substitute the butter and cream with plant-based alternatives like olive oil and coconut cream.
4. Can I add more vegetables?
   Absolutely! Sautéed bell peppers or spinach make excellent additions.
