Ingredients
- 1 lb, about 1-inch thick sirloin steak
- 2 tbsp butter (ghee or clarified for Whole30)
- 1 tbsp chopped fresh thyme
- 1 tbsp chopped fresh rosemary
- 3 minced garlic cloves
- 2 medium, cut into 1/2-inch sticks carrots
- 1 bunch (about 12 spears), trimmed asparagus
- 1 cup cherry tomatoes
- 3 tbsp olive oil
- 1 1/2 tsp divided salt
- 1 tsp divided black pepper
Instructions
- Step 1: Preheat oven to 425°F. Toss 2 peeled and cut carrots, 1 bunch trimmed asparagus, and 1 cup cherry tomatoes with 3 tbsp olive oil, 1 tsp salt, and 1/2 tsp black pepper on a large sheet pan. Spread evenly and roast for 20 minutes until tender and slightly caramelized.
- Step 2: While vegetables roast, pat dry 1 lb sirloin steak and season both sides with 1/2 tsp salt and 1/2 tsp black pepper.
- Step 3: Heat a large skillet over medium-high heat and melt 2 tbsp ghee (clarified butter). Add 3 minced garlic cloves, 1 tbsp chopped fresh thyme, and 1 tbsp chopped fresh rosemary, sautéing for 30 seconds until fragrant.
- Step 4: Add the steak to the skillet and sear for 4-5 minutes per side for medium-rare, spooning the herb butter over the steak as it cooks.
- Step 5: Remove steak and let rest for 5 minutes. Serve sliced steak alongside the roasted vegetables.
