Garlic Butter Pork Tenderloin and Veggies – A Cozy, One-Pan Dinner
Ingredients
Method
- Preheat and prep. Heat the oven to 425°F (220°C). Line a large sheet pan with parchment or lightly oil it.Pat the pork tenderloin dry with paper towels.
- Season the pork. In a small bowl, mix 1 tablespoon olive oil, 1/2 teaspoon salt, black pepper, paprika, garlic powder, and dried thyme. Rub this mixture all over the pork. Set aside.
- Toss the veggies. On the sheet pan, toss potatoes, broccoli, bell pepper, and onion with the remaining 1 tablespoon olive oil and 1/2 teaspoon salt.Spread into a single layer, keeping space in the center for the pork.
- Make the garlic butter. In a bowl, combine softened butter, minced garlic, parsley, lemon zest, and a pinch of red pepper flakes if using. Stir until smooth.
- Roast. Place the seasoned pork in the center of the pan. Roast for 10 minutes.
- Butter baste and finish. Pull the pan out, smear about half the garlic butter over the top of the pork, and toss the veggies lightly.Return to the oven and roast 8–12 more minutes, until the thickest part of the pork hits 140–145°F (60–63°C) on an instant-read thermometer.
- Rest the meat. Transfer the pork to a cutting board and tent loosely with foil. Rest for 5–8 minutes. This helps the juices redistribute so the slices stay moist.
- Final toss. Dot the remaining garlic butter over the hot veggies and toss until glossy.Slice the pork into 1/2-inch medallions and spoon any pan juices over the top.
- Serve. Finish with extra parsley and a squeeze of fresh lemon. Taste and adjust salt and pepper as needed.
Why This Recipe Works
- Pork tenderloin cooks fast. It’s a lean cut that reaches perfect doneness in under 25 minutes, making it weeknight-friendly.
- Garlic butter adds flavor and moisture. A quick baste at the end gives the pork gloss, flavor, and keeps it from drying out.
- Sheet-pan veggies roast alongside the pork. Everything cooks on one pan, so timing is simple and cleanup is easy.
- High-heat roasting builds a crust. A hot oven browns the outside while keeping the inside tender and juicy.
- Simple seasonings, big payoff. Salt, pepper, paprika, and herbs let the pork shine without overpowering it.

How to Make It
- Preheat and prep. Heat the oven to 425°F (220°C). Line a large sheet pan with parchment or lightly oil it.
Pat the pork tenderloin dry with paper towels.
- Season the pork. In a small bowl, mix 1 tablespoon olive oil, 1/2 teaspoon salt, black pepper, paprika, garlic powder, and dried thyme. Rub this mixture all over the pork. Set aside.
- Toss the veggies. On the sheet pan, toss potatoes, broccoli, bell pepper, and onion with the remaining 1 tablespoon olive oil and 1/2 teaspoon salt.
Spread into a single layer, keeping space in the center for the pork.
- Make the garlic butter. In a bowl, combine softened butter, minced garlic, parsley, lemon zest, and a pinch of red pepper flakes if using. Stir until smooth.
- Roast. Place the seasoned pork in the center of the pan. Roast for 10 minutes.
- Butter baste and finish. Pull the pan out, smear about half the garlic butter over the top of the pork, and toss the veggies lightly.
Return to the oven and roast 8–12 more minutes, until the thickest part of the pork hits 140–145°F (60–63°C) on an instant-read thermometer.
- Rest the meat. Transfer the pork to a cutting board and tent loosely with foil. Rest for 5–8 minutes. This helps the juices redistribute so the slices stay moist.
- Final toss. Dot the remaining garlic butter over the hot veggies and toss until glossy.
Slice the pork into 1/2-inch medallions and spoon any pan juices over the top.
- Serve. Finish with extra parsley and a squeeze of fresh lemon. Taste and adjust salt and pepper as needed.
Storage Instructions
- Refrigerator: Store sliced pork and veggies in airtight containers for up to 3 days.
- Freezer: Pork freezes well for up to 2 months. Wrap tightly and thaw overnight in the fridge.
Veggies can be frozen, but their texture will soften once reheated.
- Reheating: Warm gently in a 300°F (150°C) oven for 10–12 minutes, or reheat in a skillet with a splash of broth. Avoid microwaving on high to keep the pork from drying out.
- Leftover ideas: Add sliced pork to grain bowls, make a quick sandwich with arugula and mustard, or toss with pasta and the leftover garlic butter.
Why This is Good for You
- Lean protein: Pork tenderloin is a lean cut, offering protein without much saturated fat.
- Veggie variety: Potatoes, broccoli, peppers, and onions bring fiber, vitamins C and K, potassium, and antioxidants.
- Balanced meal: You get protein, complex carbs, and healthy fats in one pan, keeping you full and satisfied.
- Flavor without excess: Garlic, herbs, and lemon add brightness so you can use moderate butter and still feel indulged.
Common Mistakes to Avoid
- Overcooking the pork. Tenderloin dries out quickly past 145°F (63°C). Use a thermometer and pull it as soon as it hits temp.
- Skipping the rest. Cutting too soon lets the juices spill.
A short rest keeps the slices juicy.
- Crowding the pan. If your vegetables overlap too much, they steam instead of roast. Use a large sheet pan or two smaller ones.
- Cold meat in a hot oven. If the pork is icy-cold from the fridge, the outside may overcook before the center is done. Let it sit at room temp for 15–20 minutes before roasting.
- Uneven veggie sizes. Keep pieces similar so everything cooks at the same rate, especially the potatoes.
Recipe Variations
- Herb-forward: Swap paprika for rosemary and thyme, and add a teaspoon of Dijon to the garlic butter.
- Citrus-garlic: Use orange zest instead of lemon and finish with a splash of fresh orange juice over the veggies.
- Smoky maple: Add 1 tablespoon maple syrup and 1/2 teaspoon chipotle powder to the butter for a sweet-heat glaze.
- Mediterranean: Use oregano and basil, add cherry tomatoes and olives to the pan, and finish with crumbled feta.
- Low-carb swap: Replace potatoes with cauliflower florets or zucchini.
Roast zucchini only in the second half to prevent mushiness.
- Grill version: Sear the pork over medium-high heat for 2–3 minutes per side, then move to indirect heat until 140–145°F. Grill veggies in a basket, then toss with the garlic butter.
FAQ
How do I remove the silver skin from pork tenderloin?
Slide a small sharp knife under the thin, shiny membrane at one end, then angle the blade slightly up and run it along to separate it from the meat. Work in small sections to avoid trimming away too much meat.
Can I use pork loin instead of tenderloin?
Pork loin is thicker and takes much longer to cook, so timing won’t match.
If using loin, roast it separately at a lower temperature and add the veggies later, or stick with tenderloin for best results.
What if I don’t have a thermometer?
You can check by cutting into the center; it should be slightly rosy with clear juices. Still, a thermometer is the most reliable way to get juicy pork every time.
Which vegetables roast best here?
Sturdy veggies like potatoes, carrots, Brussels sprouts, broccoli, cauliflower, bell peppers, and red onions work well. Keep pieces similar in size and add quicker-cooking ones (like zucchini) later in the roast.
Can I make the garlic butter ahead?
Yes.
Mix and refrigerate for up to 5 days or freeze for 2 months. Soften slightly before using so it spreads easily over the pork.
How do I keep the pork from sticking to the pan?
Use parchment, a light coating of oil, or a well-seasoned sheet pan. Don’t move the pork too early; a good sear will naturally release from the pan.
Is this recipe gluten-free?
Yes, it’s naturally gluten-free.
Just make sure your spices and butter are certified gluten-free if cross-contamination is a concern.
