Why This Recipe Works for Keto Dieters

Before we jump into the recipe, let’s talk about why steak and mushrooms are a great choice for a keto meal.

• High in Protein & Healthy Fats – Steak is loaded with protein and healthy fats, keeping you full and energized.
• Low in Carbs – Mushrooms add texture and flavor without adding unnecessary carbs.
• One-Pan Cooking – Less cleanup, more time to enjoy your meal.
• Packed with Flavor – Garlic, butter, and fresh herbs bring everything together.

Now, let’s get straight into what you’ll need and how to cook it to perfection.

Ingredients for Keto Steak and Mushroom Skillet

You don’t need fancy ingredients to make this dish. Simple, fresh, and flavorful is the way to go.

For the Steak & Mushrooms:

• 2 Ribeye or Sirloin steaks (about 1-inch thick)
• 2 tbsp olive oil
• 2 tbsp butter
• 8 oz mushrooms (sliced) – cremini or baby bella work great
• 3 cloves garlic (minced)
• 1 tsp fresh thyme (or ½ tsp dried)
• 1 tsp fresh rosemary (or ½ tsp dried)
• Salt and black pepper (to taste)
• ¼ cup beef broth
• 2 tbsp heavy cream (optional, for extra richness)

Step-by-Step Cooking Instructions

1. Prepare the Steaks

• Take the steaks out of the fridge 30 minutes before cooking to bring them to room temperature. This helps them cook evenly.
• Pat them dry with paper towels to remove excess moisture (this helps with getting a nice crust).
• Season both sides generously with salt and black pepper.

2. Sear the Steaks

• Heat 1 tbsp olive oil in a cast-iron skillet over medium-high heat.
• Once the oil is hot, add the steaks and cook for 3-5 minutes per side, depending on your preferred doneness.
  • Rare: 3 minutes per side
  • Medium-rare: 4 minutes per side
  • Medium: 5 minutes per side
• Add 1 tbsp butter to the skillet in the last minute and spoon it over the steaks for extra flavor.
• Remove the steaks from the skillet and let them rest on a plate for 5-10 minutes (don’t skip this step, or the juices will run out when you cut into them).

3. Cook the Mushrooms

• In the same skillet, add the remaining 1 tbsp olive oil and 1 tbsp butter.
• Toss in the sliced mushrooms and sauté for about 5 minutes, stirring occasionally.
• Add the garlic, thyme, and rosemary, and cook for another 1-2 minutes until fragrant.
• Pour in the beef broth to deglaze the pan, scraping up any browned bits from the bottom (that’s where the flavor is).
• Let it simmer for a minute, then stir in heavy cream if using.

4. Bring It All Together

• Slice the rested steaks and place them back in the skillet with the mushrooms.
• Spoon the sauce over the steak and let everything heat for another minute or two.
• Serve immediately with your favorite keto sides.
