Ingredients
Instructions
- Preheat oven to 425°F (220°C). Wash and dry all produce. Cut sweet potatoes into ½-inch cubes. Strip thyme leaves from stems and finely chop; discard stems.
- On a baking sheet, toss sweet potatoes with half the chopped thyme and a drizzle of olive oil. Season with salt and pepper. Roast for about 25 minutes, tossing halfway through, until tender and lightly crisped.
- After sweet potatoes have roasted for 12 minutes, spread green beans on another baking sheet. Drizzle with olive oil, season with salt and pepper and toss to coat. Roast for about 12 minutes, until tender and slightly browned.
- Meanwhile, heat a drizzle of olive oil in a large skillet over medium-high heat. Season steak all over with salt and pepper. Cook to desired doneness, 4-7 minutes per side for medium-rare. Transfer steak to a cutting board and let rest for 5 minutes.
- Reduce heat to medium-low. Add beef demi-glace, ⅓ cup water and remaining chopped thyme to the skillet, scraping up any browned bits. Increase heat to medium-high and simmer until sauce thickens, 1-2 minutes. If sauce becomes too thick, add a splash of water. Remove from heat and stir in butter until melted. Season with salt and pepper.
- Sprinkle sliced almonds over the roasted green beans and sweet potatoes. Thinly slice the steak against the grain. Divide vegetables and steak among plates. Drizzle with the thyme pan sauce and serve immediately.
Recipe Tips
For even cooking, let the steak come to room temperature for 20 minutes before searing.
If you prefer your steak more well-done, cook an additional 2-3 minutes per side.
To save time, you can roast the sweet potatoes and green beans on separate racks simultaneously.
FAQ
Can I use a different cut of steak?
Yes, ribeye or New York strip work well, but adjust cooking time accordingly.
What can I substitute for beef demi-glace?
You can use 1 cup of beef broth simmered until reduced by half, but the flavor will be less intense.
Can I make this recipe dairy-free?
Yes, omit the butter or use a dairy-free alternative. The sauce will still be delicious.
