The secret is in the technique: we sear the steak to a perfect crust, then use the same pan to crisp up sweet potatoes until they're golden and caramelized. The garlic butter ties it all together, infusing every bite with savory richness. It's a balanced meal that feels indulgent but is actually quite nutritious.
Whether you're cooking for a weeknight family dinner or impressing guests, this recipe delivers. The sweet potatoes are naturally sweet, the steak is juicy, and the garlic butter is the kind of thing you'll want to put on everything. Let's get cooking.
Why You'll Love This Recipe
About the Ingredients
2 lbs (900g) sweet potatoes, peeled and cut into 1-inch cubes
Look for firm, smooth-skinned sweet potatoes. If you prefer, you can leave the skin on for extra fiber and texture.
3 tablespoons olive oil, divided
Use a high-quality extra virgin olive oil for better flavor. You can substitute avocado oil for a higher smoke point.
1½ lbs (680g) flank steak or sirloin, about 1 inch thick
Flank steak is lean and flavorful. If using sirloin, it's a bit more tender. Both work well.
4 cloves garlic, minced
Fresh garlic is key. You can use 1 teaspoon garlic powder in a pinch, but fresh gives the best punch.
2 tablespoons unsalted butter
Use unsalted so you can control the salt. If you only have salted, reduce the added salt in the recipe.
1 teaspoon smoked paprika
Smoked paprika adds a smoky depth. Regular paprika works, but smoked is better. You can also use chipotle powder for heat.
1 teaspoon dried thyme
Dried thyme is convenient. If you have fresh, use 1 tablespoon chopped.
1 teaspoon salt, plus more to taste
Use kosher salt for better control. Sea salt also works.
½ teaspoon black pepper, freshly ground
Freshly ground pepper has more aroma. Pre-ground works, but fresh is worth it.
2 tablespoons chopped fresh parsley, for garnish
Parsley adds a fresh, bright finish. You can skip it or use chives instead.
Tips & Tricks
Don't overcrowd the pan
If you add too many sweet potatoes at once, they'll steam instead of crisp. Work in batches if needed.
Pat the steak dry
Before searing, pat the steak with paper towels to remove excess moisture. This ensures a good crust.
Let the steak rest
Resting allows the juices to redistribute, keeping the meat tender and flavorful. Don't skip it.
Pro Tips
Step-by-Step Instructions
1. Prep the Sweet Potatoes
Preheat your oven to 400°F (200°C). Toss the sweet potato cubes with 2 tablespoons of olive oil, ½ teaspoon salt, and ¼ teaspoon pepper. Spread them in a single layer on a baking sheet. Roast for 20-25 minutes, flipping halfway, until golden brown and tender when pierced with a fork.
2. Season the Steak
While the potatoes roast, pat the steak dry with paper towels. Rub it with the remaining 1 tablespoon olive oil, 1 teaspoon salt, ½ teaspoon pepper, and the smoked paprika. Let it sit at room temperature for 15 minutes to take the chill off.
3. Sear the Steak
Heat a large cast-iron skillet over high heat until smoking hot (about 2-3 minutes). Place the steak in the pan and sear for 3-4 minutes per side for medium-rare (internal temp 130°F/54°C), or until nicely browned. Adjust time for desired doneness.
4. Add Garlic Butter
In the last minute of cooking, add the butter and minced garlic to the pan. Tilt the pan and spoon the melted butter over the steak continuously. This bastes the steak and infuses it with garlic flavor.
5. Rest the Steak
Remove the steak from the pan and place it on a cutting board. Loosely tent with foil and let it rest for 5-10 minutes. This allows the juices to redistribute.
6. Crisp the Potatoes in the Skillet
After the steak rests, drain excess fat from the skillet, leaving about 1 tablespoon. Add the roasted sweet potatoes to the hot skillet in a single layer. Cook over medium-high heat, without stirring too often, for 3-4 minutes per side, until they get extra crispy and golden brown on the edges.
7. Slice and Serve
Thinly slice the steak against the grain. Serve the steak over the crispy sweet potatoes, sprinkle with thyme and fresh parsley, and drizzle with any remaining garlic butter from the pan.
Delicious Variations
Add vegetables
Toss in some broccoli or asparagus with the sweet potatoes during the last 10 minutes of roasting.
Make it spicy
Add ½ teaspoon of cayenne pepper to the seasoning mix for the steak.
Use chicken
Swap the steak for chicken thighs; adjust cooking time to 5-6 minutes per side until cooked through.
How to Store Garlic Steak And Crispy Sweet Potatoes
Refrigerator
Store leftovers in an airtight container for up to 3 days.
Freezer
You can freeze the cooked steak and potatoes separately for up to 2 months. Thaw overnight in the fridge.
Reheating
Reheat in a skillet over medium heat until warmed through, or in the microwave. For crispy potatoes, use a toaster oven or air fryer.
Frequently Asked Questions
Q: Can I use a different cut of steak?
Yes, you can use sirloin, ribeye, or strip steak. Just adjust cooking time based on thickness and desired doneness.
Q: How do I know when the steak is done?
Use a meat thermometer: 125°F (52°C) for rare, 130°F (54°C) for medium-rare, 140°F (60°C) for medium. Or use the finger test: compare the firmness of the steak to the fleshy part of your thumb.
Q: Can I make this dairy-free?
Absolutely. Use a high-quality olive oil or vegan butter instead of regular butter. The flavor will still be rich.
Q: Why are my sweet potatoes not crispy?
Make sure they are in a single layer on the baking sheet and not overcrowded. Also, the pan should be hot when you add them for the final crisping.
