Ingredients
Let’s break down the ingredients that come together to create this flavorful, comforting dish:
Steak: The star of the show! A good-quality steak—whether it’s ribeye, sirloin, or your preferred cut—gets seared to juicy perfection, giving you that satisfying savory bite. This is the protein that takes center stage and makes the meal feel indulgent.
Olive Oil: Used to sear the steak and bring out its rich flavor, olive oil also adds a smooth, silky texture to the green sauce.
Garlic: Fresh garlic is essential for the green sauce, providing that bold, aromatic depth of flavor. It pairs perfectly with the freshness of the herbs.
Herbs (Parsley, Basil, Cilantro): A fresh herb mix creates the vibrant, fragrant green sauce. This combo brightens up the steak and balances the richness of the mashed sweet potatoes.
Lemon Juice: A splash of lemon juice adds a zesty, refreshing acidity that cuts through the richness of the steak and enhances the flavors of the sauce.
Sweet Potatoes: Naturally sweet and creamy, mashed sweet potatoes are the perfect complement to the savory steak and tangy green sauce. They’re comforting, filling, and delicious.
Butter: For the mashed sweet potatoes, butter adds richness and smoothness, making them luxuriously creamy.
Salt and Pepper: Essential for seasoning both the steak and the mashed potatoes, salt and pepper bring out the natural flavors of all the ingredients.

Instructions
Let’s dive into the steps to create this mouthwatering meal:
Preheat Your Pan: Start by heating a large skillet over medium-high heat for the steak. Preheating is key for getting that nice sear on the meat.
Prepare the Green Sauce: In a food processor or blender, combine the parsley, basil, cilantro, garlic, lemon juice, olive oil, salt, and pepper. Pulse until the sauce reaches a smooth consistency. Set it aside and let the flavors meld together.
Cook the Steak: Season the steak generously with salt and pepper. Once your skillet is hot, add a bit of olive oil and sear the steak for a few minutes on each side, depending on your preferred level of doneness. Remove the steak from the pan and let it rest while you prepare the mashed sweet potatoes.
Make the Mashed Sweet Potatoes: Peel and chop the sweet potatoes, then boil them in salted water until they’re fork-tender. Drain the potatoes and mash them with butter, salt, and pepper until they’re creamy and smooth.
Serve and Assemble: Once the steak has rested, slice it against the grain and serve it over a bed of mashed sweet potatoes. Drizzle the fresh green sauce over the top, and garnish with extra herbs if desired.
Enjoy: Dig in! Take a bite of juicy steak, a scoop of creamy mashed sweet potatoes, and a hit of vibrant green sauce. Pure bliss!

How to Serve Steak with Green Sauce and Mashed Sweet Potatoes
This dish is hearty enough to stand on its own, but here are a few ideas to complement it:
Green Salad: A crisp, refreshing green salad with a light vinaigrette is the perfect side to cut through the richness of the steak and mashed potatoes.
Roasted Vegetables: Roasted vegetables, such as carrots, broccoli, or asparagus, would make a colorful and nutritious side to balance the meal.
Crispy Bread: Serve with some crispy bread or a soft baguette to soak up any extra green sauce or mashed potato goodness.
Wine Pairing: If you’re in the mood for a drink, a glass of red wine (such as a bold Cabernet Sauvignon) would pair beautifully with the steak and the savory flavors of the meal.
Additional Tips
Here are some extra tips to ensure your steak and mashed sweet potatoes turn out perfect every time:
Use Room Temperature Steak: Before cooking, let your steak come to room temperature. This helps it cook more evenly and results in a juicier, more tender steak.
Rest the Steak: After cooking, let the steak rest for at least 5 minutes. This allows the juices to redistribute and keeps the steak moist.
Customize the Green Sauce: Don’t be afraid to play around with the green sauce. Add a little heat with chili flakes or experiment with different herbs like tarragon or mint.
Make Extra Mashed Potatoes: Mashed sweet potatoes make a great side dish for other meals too! Make extra and store them in the fridge for a quick and easy side later in the week.
Use Fresh Herbs: Fresh herbs really make a difference in the flavor of the green sauce. Try not to substitute dried herbs if possible—fresh is best.
