Ingredients

• 500 grams Beef sirloin (or chuck steak)
• 1 teaspoon Salt
• 0.5 teaspoon Ground black pepper
• 2 tablespoons Olive oil
• 2 tablespoons Unsalted butter
• 2 units Garlic cloves, minced
• 200 grams White button mushrooms, sliced
• 250 milliliters Beef broth (low sodium)
• 150 milliliters Heavy cream
• 2 units Sprigs of fresh thyme
• 1 tablespoon Fresh parsley, chopped (for garnish)

Directions

Step 1

Pat the beef sirloin dry with paper towels and cut it into bite-sized strips, about 1 inch wide.

Step 2

Season the beef with salt and ground black pepper, making sure it is evenly coated.

Step 3

In a large skillet over medium-high heat, heat 1 tablespoon of olive oil. Sear the beef strips in batches until browned on the outside but still slightly pink inside, about 2 minutes per side. Remove the beef and set aside.

Step 4

Lower the heat to medium and add the remaining 1 tablespoon of olive oil and 2 tablespoons of butter to the skillet. Add the minced garlic and cook for 1 minute until fragrant.

Step 5

Stir in the sliced mushrooms and sauté for 5-7 minutes, or until the mushrooms are browned and tender.

Step 6

Pour in the beef broth and bring it to a gentle simmer. Scrape the bottom of the skillet with a wooden spoon to deglaze and incorporate all the flavorful browned bits.

Step 7

Add the heavy cream and fresh thyme sprigs to the skillet, stirring well. Let the sauce simmer for 8-10 minutes until it thickens slightly.

Step 8

Return the seared beef strips to the skillet and cook for another 5 minutes, ensuring the meat is warmed through and tender.

Step 9

Taste the sauce and adjust the seasoning with additional salt and pepper if needed.

Step 10

Remove the thyme sprigs before serving. Garnish the dish with chopped fresh parsley.

Step 11

Serve the keto tender beef in rich mushroom sauce warm, optionally paired with cauliflower mash or roasted vegetables for a complete keto-friendly meal.
