Step 2: Sear the Steak
Pat steak pieces dry and season with salt and pepper. Increase skillet heat to high. Sear steak bites in batches for 1–2 minutes per side until browned. Do not overcrowd. Remove from skillet and set aside.
Step 3: Make the Garlic Butter
Reduce heat to medium-low. In the same skillet, melt butter and add minced garlic. Cook for about 1 minute until fragrant (do not brown). Stir in parsley and red pepper flakes if using.
Step 4: Combine Steak and Potatoes
Return potatoes and steak to the skillet. Toss to coat evenly with garlic butter.
Step 5: Add Cheese and Finish
Sprinkle mozzarella and cheddar evenly over the steak and potatoes. Cover with lid or place under a broiler for 2–3 minutes until the cheese melts and bubbles.
Step 6: Serve
Garnish with more parsley and serve hot.
Tips
Use a well-seasoned cast iron skillet for the best sear on steak and crispy edges on potatoes.
Cut potatoes uniformly to ensure even cooking.
Pat steak dry before searing to avoid steaming and ensure browning.
Let cheese melt under the broiler for a golden finish, but keep a close eye to avoid burning.
Variations
Swap steak for chicken, kielbasa, or shrimp.
Add veggies like bell peppers, mushrooms, or broccoli during the last few minutes of potato cooking.
Use pepper jack for a spicy version.
For a low-carb version, replace potatoes with cauliflower florets.
