🕒 Time & Yield

  • Prep Time: 10 minutes

  • Cook Time: 20 minutes

  • Total Time: 30 minutes

  • Servings: 4


🛒 Ingredients

For the Steak

  • 4 ribeye or sirloin steaks (about 1 inch thick)

  • 1½ teaspoons sea salt

  • 1 teaspoon black pepper

  • 1 teaspoon Italian seasoning

  • 1 tablespoon avocado oil (or olive oil)

  • 1 tablespoon butter

For the Creamy Tuscan Sauce

  • 3 tablespoons butter

  • 4 cloves garlic, minced

  • ½ cup sun-dried tomatoes (in oil), drained and sliced

  • 1½ cups heavy cream

  • ½ cup chicken broth (low sodium)

  • ¾ cup freshly grated Parmesan cheese

  • 1 teaspoon Italian seasoning

  • ½ teaspoon red pepper flakes (optional)

  • 2 cups fresh spinach

  • Salt and pepper to taste


🔥 Instructions

1️⃣ Prep the Steaks

  • Remove steaks from the refrigerator 20–30 minutes before cooking to bring to room temperature.

  • Pat dry with paper towels.

  • Season both sides generously with salt, pepper, and Italian seasoning.


2️⃣ Sear the Steaks

  1. Heat a large cast-iron skillet over medium-high heat.

  2. Add avocado oil and 1 tablespoon butter.

  3. Once hot, place steaks in the pan without overcrowding.

  4. Sear for 3–4 minutes per side for medium-rare (adjust to preferred doneness).

  5. Remove steaks and tent loosely with foil to rest.

💡 Tip: Use a meat thermometer—130°F (54°C) for medium-rare, 140°F (60°C) for medium.


3️⃣ Make the Creamy Tuscan Sauce

  1. In the same skillet (do not wipe clean), reduce heat to medium.

  2. Add 3 tablespoons butter.

  3. Sauté garlic for about 30 seconds until fragrant.

  4. Stir in sun-dried tomatoes and cook 1 minute.

  5. Pour in chicken broth to deglaze the pan, scraping up browned bits.

  6. Add heavy cream and Italian seasoning. Simmer 3–5 minutes until slightly thickened.

  7. Stir in Parmesan cheese and whisk until smooth.

  8. Add spinach and cook until wilted (about 2 minutes).

  9. Adjust seasoning with salt, pepper, and red pepper flakes if desired.

The sauce should be thick, creamy, and spoon-coating.


4️⃣ Finish the Dish

  • Return steaks to the skillet.

  • Spoon sauce over the top.

  • Simmer together for 2–3 minutes to blend flavors.

  • Remove from heat and let rest 5 minutes before serving.

Use coconut cream and nutritional yeast instead of heavy cream and Parmesan.

Extra Flavor Boost:
Add mushrooms or a splash of dry white wine (cook off alcohol).

Spicy Version:
Increase red pepper flakes or add a dash of cayenne.

Budget Option:

🥡 Storage & Reheating

  • Store leftovers in an airtight container up to 3 days in the refrigerator.

  • Reheat gently over low heat to prevent sauce separation.

  • Add a splash of cream when reheating if needed.


⭐ Pro Tips for Perfect Keto Steak

  • Always let steak rest before slicing.

  • Don’t overcrowd the pan—this prevents proper searing.

  • Freshly grated Parmesan melts smoother than pre-shredded.

  • Cast iron gives the best crust.
