Instructions (Garlic Butter Steak and Potatoes Skillet)
Step 1: Roast the Potatoes
- Preheat your oven to 375°F.
- Toss quartered red potatoes with olive oil, salt, and pepper.
- Spread evenly on a parchment-lined baking sheet and roast for 30 minutes, flipping halfway for crispy potatoes.

Mini Tip: Use small red or Yukon gold potatoes with thinner skins, which means crispier edges.
Step 2: Make the Garlic Butter Marinade
- In a bowl, combine softened butter, minced garlic, fresh herbs, red pepper flakes, and coconut aminos (or soy sauce).
- Whisk until smooth and aromatic.
Mini Tip: Room-temperature butter mixes easily and coats the steak evenly.
Step 3: Sear the Steak Bites
- Cut steak into 1-inch cubes.
- Heat your cast-iron skillet over high heat. It should sizzle instantly when the steak hits the surface.
- Sear steak bites in batches for 3–4 minutes per side, until a dark crust forms.
Pro Tip: Don't overcrowd the pan, let the steak sear, not steam!
Step 4: Combine and Bake
- Add roasted potatoes to the skillet beside the steak.
- Pour any remaining buttery garlic sauce over everything.
- Bake for 5 minutes to bring all the flavors together.
Step 5: Garnish and Serve
Remove the skillet from the oven, sprinkle with fresh parsley, and serve hot.
