½ cup sun-dried tomatoes (in oil), drained and sliced
-
1½ cups heavy cream

🔥 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
-
Heat a large cast-iron skillet over medium-high heat.
-
Add avocado oil and 1 tablespoon butter.
-
Once hot, place steaks in the pan without overcrowding.
-
Sear for 3–4 minutes per side for medium-rare (adjust to preferred doneness).
-
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
-
In the same skillet (do not wipe clean), reduce heat to medium.
-
Add 3 tablespoons butter.
-
Sauté garlic for about 30 seconds until fragrant.
-
Stir in sun-dried tomatoes and cook 1 minute.
-
Pour in chicken broth to deglaze the pan, scraping up browned bits.
-
Add heavy cream and Italian seasoning. Simmer 3–5 minutes until slightly thickened.
-
Stir in Parmesan cheese and whisk until smooth.
-
Add spinach and cook until wilted (about 2 minutes).
-
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.
