Step-by-Step Instructions
This meal comes together with a bit of multitasking, but the steps are straightforward. Follow along to create a dinner that’s as delicious as it is impressive.
Step 1: Bake the Sweet Potato
Preheat your oven to 400°F (200°C). Scrub the sweet potato clean, prick it a few times with a fork, and wrap it in aluminum foil to retain moisture. Place it on a baking sheet and bake for 45–60 minutes, or until fork-tender (a knife should slide in easily). Once done, unwrap, slice open lengthwise, and fluff the inside with a fork. Add 1 tablespoon butter, 1 tablespoon sour cream (if using), a pinch of salt, and a dash of cinnamon for a hint of warmth. Set aside and keep warm.
Step 2: Roast the Mushrooms and Onions
While the sweet potato bakes, prepare the vegetables. On the same baking sheet, toss 1 cup halved mushrooms and 1 sliced red onion with 1 tablespoon olive oil, a pinch of salt, pepper, and 1 teaspoon balsamic vinegar. Spread them in a single layer and roast at 400°F for 20–25 minutes, stirring halfway through, until the mushrooms are golden and the onions are caramelized and tender. Remove from the oven and cover to keep warm.
Step 3: Prepare the Ribeye Steak
Take the ribeye steak out of the fridge 20–30 minutes before cooking to bring it to room temperature for even cooking. Pat it dry with paper towels and season generously on both sides with kosher salt and freshly ground black pepper. Heat a cast-iron skillet or grill pan over high heat until smoking hot, then add 1 tablespoon olive oil. Place the steak in the skillet and sear for 3–4 minutes per side for medium doneness (135°F internal temperature), adjusting time for your preferred doneness.
Step 4: Baste the Steak
In the last minute of cooking, add 1 tablespoon butter, 2 smashed garlic cloves, and a sprig of rosemary or thyme to the skillet. Tilt the pan slightly and spoon the melted butter and aromatics over the steak repeatedly for about 30 seconds to infuse it with flavor. Remove the steak from the skillet and let it rest on a cutting board for 5–10 minutes to allow the juices to redistribute.
Step 5: Plate and Serve
Slice the rested steak against the grain into thick strips. Plate the steak alongside the baked sweet potato and roasted mushrooms and onions. Spoon any remaining pan juices over the steak for extra flavor. Serve immediately, savoring the combination of savory, sweet, and earthy notes.
Serving Suggestions
This hearty meal is a complete plate, but you can enhance it with these ideas:
- Salad: Add a simple arugula salad with lemon vinaigrette for freshness.
- Bread: Serve with a crusty roll or garlic bread to soak up the steak juices.
- Wine Pairing: A bold red like Cabernet Sauvignon or Malbec pairs beautifully (omit for non-alcoholic preferences).
- Holiday Feast: Include this as the centerpiece for a cozy dinner party.
- Extra Sauce: Drizzle with chimichurri or a dollop of garlic aioli for a twist.
Tips for Success
- Room temperature steak: Let the steak sit out before cooking for even searing.
- Don’t skip the rest: Resting the steak keeps it juicy and tender.
- Sweet potato shortcut: Microwave the sweet potato for 5–7 minutes to speed up cooking.
- Mushroom variety: Mix cremini with shiitake or oyster mushrooms for more depth.
- Check doneness: Use a meat thermometer for precision (135°F for medium).
Variations to Try
Make this meal your own with these creative ideas:
- Spicy Twist: Add a pinch of chili flakes to the mushrooms and onions.
- Sweet Potato Topping: Swap sour cream for maple syrup or brown sugar.
- Herb Swap: Use sage or oregano instead of rosemary for the steak.
- Veggie Boost: Roast Brussels sprouts or asparagus alongside the mushrooms.
- Low-Carb Option: Swap the sweet potato for mashed cauliflower.
Storage and Reheating
This meal is best enjoyed fresh, but leftovers can be stored:
- Refrigerate: Store components separately in airtight containers in the fridge for up to 3 days.
- Freeze: Freeze the cooked steak and veggies (not the sweet potato) for up to 1 month. Thaw in the fridge before reheating.
- Reheat: Warm the steak and veggies in a 350°F oven for 10 minutes, or microwave for 1–2 minutes. Reheat the sweet potato in the oven or microwave.
- Make Ahead: Roast the vegetables and bake the sweet potato a day in advance; reheat before serving.
