Ingredients

• 1.5 lbs Beef tenderloin
• 3 tbsp Olive oil
• 2 tbsp Dijon mustard
• 1 tbsp Fresh rosemary
• 1 tbsp Fresh thyme
• 1 tsp Garlic powder
• 1 tsp Salt
• 1/2 tsp Black pepper
• 12 oz Baby carrots
• 12 oz Zucchini
• 6 oz Red onion
• 2 tbsp Fresh parsley

Instructions

1. Step 1: In a small bowl, combine 1 tbsp olive oil, 2 tbsp Dijon mustard, 1 tbsp minced fresh rosemary, 1 tbsp fresh thyme leaves, 1 tsp garlic powder, 1 tsp salt, and 1/2 tsp black pepper. Rub this mixture evenly over the 1.5 lbs beef tenderloin, pressing to adhere. Let rest at room temperature for 30 minutes while prepping vegetables.
2. Step 2: Preheat oven to 425°F (220°C). Place 12 oz baby carrots, 12 oz sliced zucchini, and 6 oz red onion wedges on a large rimmed baking sheet. Drizzle with 2 tbsp olive oil, then sprinkle with salt and pepper to taste. Toss until evenly coated and spread in a single layer. Roast for 20-25 minutes, stirring once halfway, until vegetables are tender and golden at the edges.
3. Step 3: Heat an oven-safe skillet over medium-high heat until shimmering. Place the 1.5 lbs beef tenderloin in the skillet and sear for 2-3 minutes per side until deeply browned. Transfer skillet to the oven and roast for 15-20 minutes until internal temperature reaches 125°F (52°C) for medium-rare.
4. Step 4: Remove beef from oven and tent loosely with foil. Rest for 10 minutes while finishing vegetables. Slice beef against the grain and serve immediately with roasted vegetables, garnished with 2 tbsp chopped fresh parsley.
