Beef in Butter with Port Wine Sauce

Ingredients

• 1.5 pounds Beef cubes (such as sirloin or tenderloin) (Cut into 1-inch cubes)
• 4 tablespoons Butter (Unsalted)
• 1 medium Onion (Finely chopped)
• 2 cloves Garlic (Minced)
• 1 cup Beef broth (Low sodium)
• 0.5 cup Port wine (Ruby or Tawny)
• 1 tablespoon Brown sugar (Packed)
• 1 teaspoon Balsamic vinegar
• 1 sprig Fresh thyme (Or 1/2 teaspoon dried thyme)
• 0.5 teaspoon Salt (Or to taste)
• 0.25 teaspoon Black pepper (Freshly ground, or to taste)

Instructions

1. 1Cut the beef into 1-inch cubes if not already done. Pat dry with paper towels and season with salt and pepper.
2. 2Melt 2 tablespoons of butter in a large skillet over medium-high heat. Add the beef cubes in a single layer (work in batches if necessary) and sear on all sides until browned, about 5-7 minutes per batch. Remove the beef from the skillet and set aside.
3. 3Add the remaining 2 tablespoons of butter to the skillet. Add the chopped onion and cook until softened and translucent, about 5 minutes. Add the minced garlic and cook for another minute until fragrant.
4. 4Pour in the beef broth and port wine. Add the brown sugar, balsamic vinegar, and thyme sprig. Bring to a simmer, scraping up any browned bits from the bottom of the skillet. Return the beef to the skillet. Reduce heat to low, cover, and simmer for 15-20 minutes, or until the beef is tender.
5. 5Remove the thyme sprig. Taste and adjust seasoning with salt and pepper as needed. Serve the beef with the Port Wine Sauce over rice, mashed potatoes, or pasta.
