Start by preheating your oven to 400°F. This will ensure your potatoes roast evenly and get that perfect golden color.
Next, wash and dice the baby Yukon gold potatoes into bite-sized pieces or wedges. Aim for uniformity so they cook evenly. In a large, oven-safe skillet, add olive oil and the diced potatoes.
Add the sliced onion to the skillet along with half the minced garlic, half the thyme, half the rosemary, half the salt, half the black pepper, and half the red pepper flakes. Toss everything together to coat the potatoes and onions evenly.
Cook the mixture over medium-high heat for about 5 minutes, stirring occasionally. You’re looking for the potatoes to start browning slightly and the onions to become translucent.
Once the vegetables are looking good, stir in 2 tablespoons of butter and allow it to melt, enhancing the flavors of the dish.
Transfer the skillet to the preheated oven and bake for about 15 to 20 minutes, or until the potatoes are fork-tender and golden brown. Keep an eye on them to ensure they don’t burn.
After baking, using a pot holder, carefully remove the skillet from the oven. Transfer the potatoes to a warm plate and cover with foil to keep warm.
Now, place the skillet back on the stove over medium heat. Add the remaining 4 tablespoons of butter, the rest of the minced garlic, herbs, salt, pepper, and red pepper flakes. Stir until the butter is melted and the mixture is fragrant.
Add the steaks to the skillet. Allow them to cook undisturbed on the first side to achieve a nice sear. Flip them according to your desired doneness using a digital thermometer to check the internal temperature.
Once cooked to your preference, remove the steaks from the skillet and let them rest for 5 to 10 minutes on a cutting board or plate. This resting allows the juices to redistribute, ensuring a tender bite.
While the steaks rest, add the previously roasted potatoes back into the skillet to warm them through gently. Mix them with the buttery herb sauce left in the pan.
After resting, slice the steaks against the grain and add them back into the skillet with the potatoes. Optionally, sprinkle with freshly grated Parmesan cheese to finish.
Serve immediately and enjoy this delightful Steak and Potatoes Skillet warm and fresh!
