Ingredients

Here's everything you need for this complete sheet pan dinner.

For the Pork:

• 1½ lbs (680g) pork tenderloin, trimmed of silver skin
• 2 tablespoons olive oil, divided
• 2 teaspoons dried rosemary
• 1½ teaspoons garlic powder
• 1 teaspoon dried thyme
• 1 teaspoon paprika
• 1 teaspoon kosher salt
• ½ teaspoon black pepper

For the Vegetables:

• 1 lb (450g) baby potatoes, halved
• 3 medium carrots, peeled and cut into 2-inch pieces
• 1 red bell pepper, cut into 1-inch chunks
• 1 medium red onion, cut into wedges
• 2 cups (300g) Brussels sprouts, trimmed and halved
• 3 cloves garlic, minced
• 2 tablespoons olive oil
• 1 teaspoon kosher salt
• ½ teaspoon black pepper
• Fresh parsley for garnish

You can absolutely swap the vegetables based on what you have. Broccoli, cauliflower, zucchini, and sweet potatoes all work beautifully here. Just keep the pieces roughly the same size so everything cooks evenly.

How to Make Pork Tenderloin with Roasted Veggies

Here's the step-by-step process that makes this come together effortlessly.

1. Preheat and prep your pan. Preheat your oven to 425°F (220°C) and line a large rimmed baking sheet with parchment paper or lightly grease it with cooking spray. This prevents sticking and makes cleanup even easier.
2. Season the pork. Pat the pork tenderloin completely dry with paper towels. In a small bowl, combine the rosemary, garlic powder, thyme, paprika, salt, and pepper. Rub 1 tablespoon of olive oil all over the pork, then massage the spice mixture evenly onto all sides of the meat. The oil helps the seasonings stick and creates a beautiful crust.
3. Prepare the vegetables. In a large bowl, toss the potatoes, carrots, bell pepper, red onion, Brussels sprouts, and minced garlic with 2 tablespoons of olive oil, salt, and pepper. Make sure everything's coated evenly so the vegetables roast instead of steam.
4. Arrange everything on the pan. Spread the vegetables in a single layer on the prepared baking sheet, leaving space in the center for the pork. Place the seasoned pork tenderloin right in the middle of the vegetables. The vegetables will catch all the delicious juices as the pork cooks.
5. Roast until the pork is cooked through. Transfer the pan to the oven and roast for 25 to 30 minutes, or until the pork reaches an internal temperature of 145°F (63°C) when tested with a meat thermometer in the thickest part. The vegetables should be tender and starting to caramelize at the edges.
6. Rest the pork. Remove the pan from the oven and transfer the pork to a cutting board. Tent it loosely with aluminum foil and let it rest for 5 to 8 minutes. This step is crucial because it allows the juices to redistribute throughout the meat, keeping it incredibly tender.
7. Toss the vegetables and serve. While the pork rests, give the vegetables a quick stir on the pan to coat them in any accumulated juices. Slice the pork into ½-inch medallions, arrange them over or alongside the roasted vegetables, and garnish with fresh chopped parsley. Serve immediately while everything's hot.

What to Serve With Pork Tenderloin with Roasted Veggies

This is already a complete meal, but here are some sides that make it feel even more special:

Storage & Make-Ahead Tips

Refrigerator: Store leftover pork and vegetables in an airtight container in the fridge for up to 4 days. Reheat gently in the microwave or in a 350°F (175°C) oven for about 10 minutes until warmed through.

Freezer: Slice the cooked pork and freeze it with the vegetables in freezer-safe containers for up to 3 months. Thaw overnight in the refrigerator before reheating. The texture holds up remarkably well.

Make-Ahead: You can prep the spice rub and chop all the vegetables up to 24 hours in advance. Store them separately in the fridge, then just assemble and roast when you're ready to cook. The actual cooking time stays the same, but your active prep drops to about 5 minutes.

Meal Prep: This recipe is perfect for Sunday meal prep. Divide the sliced pork and vegetables into four containers and you've got lunch sorted for the week. It reheats beautifully and actually tastes even better the next day once the flavors have melded together.

Common Mistakes to Avoid

Frequently Asked Questions

Can I use pork loin instead of pork tenderloin?

They're different cuts. Pork loin is much larger and takes significantly longer to cook, so you'd need to adjust the timing. Pork tenderloin is the long, narrow cut that cooks quickly and stays incredibly tender. If you only have pork loin, you'll need to increase the cooking time to about 50 to 60 minutes depending on thickness.

How do I know when the pork is done without a thermometer?

Honestly, you really need a meat thermometer for pork tenderloin because the margin between perfectly cooked and overdone is so small. But if you absolutely don't have one, make a small cut in the thickest part. The meat should be slightly pink in the center with clear juices running out. If it's gray throughout, it's overcooked.

Can I use frozen vegetables for this recipe?

Fresh vegetables work best because frozen ones release too much moisture and won't caramelize properly. They'll steam instead of roast and you'll end up with a watery pan. If you must use frozen, thaw them completely, pat them very dry with paper towels, and expect them to be softer than fresh.

Why is my pork tenderloin tough?

The most common reason is overcooking. Pork tenderloin is extremely lean, so it dries out quickly if you go past 145°F internal temperature. Make sure you're using a meat thermometer and pulling it right at that temperature. Also make sure you're letting it rest before slicing, which helps retain the juices.

Can I make this on a grill instead of in the oven?

Absolutely. Preheat your grill to medium-high heat (about 400°F to 425°F). Put the vegetables in a grill basket or on a piece of heavy-duty foil with holes poked in it, and grill the pork directly on the grates. The timing will be similar, around 25 to 30 minutes, but you'll want to turn the pork every 5 to 7 minutes for even cooking. Use a meat thermometer to check for doneness.
