  • 0.5 tsp black pepper
  • 0.5 tsp smoked paprika
  • 0.5 tsp garlic powder
Garlic Butter Sauce
  • 4 tbsp unsalted butter
  • 6 garlic Minced.
  • 1 tsp fresh thyme leaves Or use 1/2 tsp dried thyme.
  • 1 tbsp fresh parsley Chopped; plus more for garnish.
  • 1 tsp soy sauce

  • 0.5 lemon lemon juice Juice of 1/2 lemon.

Equipment

  • 1 cast iron skillet

Method
 

Prep steak and season
  1. Pat the steak cubes completely dry with paper towels, then season generously with salt, black pepper, smoked paprika, and garlic powder and toss to coat evenly. Keep the seasoning on the surface for a deep golden sear.
Sear steak
  1. Heat a large cast iron skillet over high heat, add the olive oil, and let it shimmer until almost smoking. You should see light wisps of heat above the oil.
  2. Add the steak cubes in a single layer (don’t crowd the pan) and sear without moving for 1–2 minutes, until a deep brown crust forms. Flip and sear the other side for 1 minute.
  3. Remove the steak to a plate and set aside, since it will finish cooking when you return it to the sauce. Keep any steak juices on the plate.
Sear zucchini
  1. Reduce heat to medium-high, add zucchini rounds to the same pan in a single layer, and sear for 2–3 minutes per side until golden and just tender. Transfer zucchini to a plate with the steak.
Make garlic butter sauce
  1. Reduce heat to medium, add the butter, and melt it while scraping up the browned bits from the bottom of the pan. Stir until the butter looks slightly foamy and glossy.
  2. Add the minced garlic and cook for 30–45 seconds until fragrant and just golden, without letting it burn. The garlic should smell toasted but not dark.
  3. Stir in the thyme, soy sauce, red pepper flakes (if using), and lemon juice, then let the sauce bubble for 30 seconds. The sauce should look slightly reduced and glossy.
Toss and serve
  1. Return the steak and zucchini to the pan and toss in the garlic butter sauce for 1–2 minutes until fully coated and heated through. The steak should be medium to medium-rare at this point.
  2. Remove from heat, garnish with fresh parsley and an extra squeeze of lemon, then serve immediately straight from the skillet. The surface should look buttery and lightly sauced.

Notes

For the best sear, make sure the steak is fully dry before seasoning and keep the steak in a single layer during the first sear. Store leftovers in an airtight container in the refrigerator up to 3 days; reheat gently in a skillet over low heat until warmed through. Freezing is not recommended because the zucchini can soften. For a lighter option, use 2 tbsp butter plus 2 tbsp olive oil for the sauce (texture will be slightly less rich).
