High-Protein Thanksgiving Sheet Pan Dinner (Turkey Tenderloin)

This High Protein Thanksgiving Sheet Pan Dinner (Turkey Tenderloin) roasts juicy turkey with sweet potatoes, Brussels sprouts, and green beans on one pan. It gives you all the classic holiday flavors — thyme, rosemary, sage — without the sink full of dishes. Everything comes together in your oven, which means you can actually enjoy the meal instead of babysitting six pots.

Total time is 55 minutes, and it lands squarely at the beginner level. It’s perfect for a small Thanksgiving gathering, a cozy Sunday dinner, or any weeknight when you’re craving festive flavors. Each serving packs 51 grams of protein, so it’s genuinely filling. The one step worth paying attention to is pulling the turkey at exactly 165°F — a few degrees past that, and it starts drying out.

What is High Protein Thanksgiving Sheet Pan Dinner (Turkey Tenderloin)?

It’s a complete turkey dinner — protein, root vegetables, and greens — roasted together on a single rimmed baking sheet. The turkey tenderloins come out tender and herb-scented, while the sweet potatoes turn caramelized at the edges and the Brussels sprouts get crisp and nutty. You get a mix of textures in every bite: soft, crispy, and juicy all at once. I make it most often in November, but honestly, there’s no reason to wait for a holiday.

Ingredients Needed to Make High-Protein Thanksgiving Sheet Pan Dinner (Turkey Tenderloin)

You probably have most of the spice drawer items already. Here’s the full breakdown.

For the Turkey

• 2 turkey tenderloins (about 1.5 lb total) — The lean, tender cut that cooks far faster than a whole bird. Look for ones that are similar in size so they finish at the same time.
• 1 tbsp olive oil — Helps the spice rub stick and encourages browning. Avocado oil works too.
• 1/2 tsp kosher salt — Seasoning the meat directly, separate from the vegetables.
• 1/4 tsp black pepper — Freshly ground makes a noticeable difference here.

For the Spice Blend

• 1 tsp dried thyme — The backbone of the holiday flavor profile.
• 1 tsp dried rosemary — Crush it between your fingers before adding to wake it up.
• 1/2 tsp dried sage — Just enough to read as “Thanksgiving” without taking over.
• 1/2 tsp garlic powder — Savory depth without any chopping.
• 1/2 tsp onion powder — Rounds out the blend and adds a subtle sweetness.

For the Vegetables

• 1 lb sweet potatoes — Peeled and cut into 1-inch cubes. Keep them uniform so they roast evenly.
• 1 lb Brussels sprouts — Trimmed and halved. Halving helps them caramelize instead of steaming.
• 8 oz fresh green beans — Trimmed. Frozen ones get too soft here, so stick with fresh.
• 1 medium red onion — Cut into 1-inch wedges. The layers soften and sweeten as they roast.
• 1 tbsp olive oil — For tossing the vegetables so they brown rather than stick.
• 1/2 tsp kosher salt — For the vegetables, added at the tossing stage.
• Cooking spray or extra olive oil — For greasing the pan before anything touches it.

Equipment Needed

Nothing fancy required — this is a deliberately low-gear recipe.

• Large rimmed baking sheet — Rimmed matters here, since vegetables release moisture. A half-sheet pan is ideal; if yours is smaller, use two.
• Small bowl — For mixing the spice blend together before it hits the food.
• Large mixing bowl — Big enough to toss all the vegetables without spilling.
• Instant-read thermometer — The only reliable way to know the turkey hit 165°F. Don’t guess on this.
• Aluminum foil or parchment paper — For lining the pan and making cleanup a thirty-second job.

Instructions to Make High Protein Thanksgiving Sheet Pan Dinner (Turkey Tenderloin)

The whole process moves fast once the oven’s on, so read through it once before you start.

Step 1: Prep the Oven and Pan

Preheat your oven to 425°F (220°C). Line a large rimmed baking sheet with foil or parchment and grease it lightly with cooking spray or olive oil. Skipping the grease means stuck vegetables and a scrubbing session you don’t want.

Step 2: Mix the Spice Blend

In a small bowl, combine 1 teaspoon kosher salt, 1/4 teaspoon black pepper, the thyme, rosemary, sage, garlic powder, and onion powder. Stir until everything is evenly distributed. This blend gets split between the turkey and the vegetables, so mix it thoroughly.

Step 3: Season the Turkey

Pat the tenderloins dry with paper towels — dry meat browns, wet meat steams. Rub 1 tablespoon olive oil all over them, then sprinkle with half the spice mixture, pressing gently so it adheres. Set them aside while you handle the vegetables.

Step 4: Toss the Vegetables

In your large bowl, combine the sweet potatoes, Brussels sprouts, green beans, and red onion wedges. Drizzle with the remaining 1 tablespoon olive oil, then add the rest of the spice mixture and 1/2 teaspoon kosher salt. Toss until every piece is coated.

Step 5: Arrange Everything on the Pan

Spread the vegetables in a single layer, leaving a gap in the center for the turkey. Place the seasoned tenderloins in that space, nestling them among the vegetables without crowding. Overcrowding is the fastest way to end up with soggy vegetables.

Step 6: Roast

Roast for 25-30 minutes, until the thickest part of the turkey reads 165°F (74°C) and the vegetables are tender with lightly browned edges. Rotate the pan halfway through for even color. Always check the turkey with your thermometer rather than eyeballing it.

Step 7: Rest, Slice, and Serve

Pull the pan from the oven and let the turkey rest 5-10 minutes before slicing — this keeps the juices in the meat instead of on the cutting board. Slice against the grain into 1/2-inch medallions and serve right away with the roasted vegetables. A scatter of fresh parsley or thyme on top is a nice finishing touch if you have it.

What Went Wrong and How I Fixed It

Here’s what tripped me up the first few times so you can skip the learning curve.

• Overcrowding the pan — Everything steamed instead of roasting. Use two pans if your sheet is smaller than a half-sheet, and give the vegetables breathing room.
• Uneven sweet potato cubes — The small ones burned while the big ones stayed firm. Take the extra two minutes to cut them all to roughly 1 inch.
• Dry turkey — I relied on time instead of temperature. Now I start checking at the 22-minute mark and pull it the moment it hits 165°F.
• Skipping the rest — Slicing immediately sent all the juices running onto the pan. Ten minutes of patience makes a visible difference in moisture.
• Wet vegetables going in — Rinsed Brussels sprouts still damp from the sink won’t brown. Dry them with a towel before tossing.
• Old dried herbs — Spices from three years ago taste like dust. Check the date on your thyme and rosemary; fresh bottles transform this dish.

What Do I Serve With High Protein Thanksgiving Sheet Pan Dinner (Turkey Tenderloin)?

It’s a complete plate on its own, but a few extras round it out nicely.

• Greek yogurt or cottage cheese — A spoonful alongside adds creaminess and pushes the protein even higher.
• Cranberry sauce — The tartness cuts through the savory herbs and adds a bright pop of color.
• Crusty sourdough bread — Perfect for sopping up the pan juices and olive oil.
• Simple green salad — A light vinaigrette balances the rich roasted flavors without weighing things down.
• Sparkling apple cider — Festive, slightly sweet, and pairs well with the sage and thyme.
• Pumpkin pie — If you’re going full holiday mode, finish with a slice and call it a night.

Pro Tips to Make a Perfect High-Protein Thanksgiving Sheet Pan Dinner (Turkey Tenderloin)

A few small moves separate a good tray from a great one.

• Dry the turkey thoroughly — Paper towels remove surface moisture so the oil and spices cling properly and the meat browns instead of steaming.
• Cut vegetables evenly — Uniform 1-inch pieces cook at the same rate. This single habit eliminates most of the timing guesswork.
• Rotate the pan halfway — Most home ovens have hot spots. A quick 180-degree turn at the 15-minute mark keeps everything browning evenly.
• Invest in a meat thermometer — Turkey tenderness is about temperature, not time. 165°F is the target, every time.
• Add protein-boosting sides — Serving with Greek yogurt or cottage cheese adds a few extra grams per plate without changing the recipe.
• Let the pan rest before slicing — Those 5-10 minutes let the juices redistribute, and the meat stays noticeably moister.
• Save the pan juices — Spoon them over the sliced turkey at serving time. Free flavor, zero effort.

Variations of High Protein Thanksgiving Sheet Pan Dinner (Turkey Tenderloin)

Once you know the method, it’s easy to adapt.

• Maple-Dijon version — Whisk 2 tablespoons Dijon mustard with 1 tablespoon maple syrup and brush it over the turkey before roasting.
• Extra-protein swap — Serve the sliced turkey over a bed of quinoa or alongside a scoop of cottage cheese for a bigger protein hit.
• Root vegetable mix — Replace the sweet potatoes with parsnips, carrots, or butternut squash.
• Spicy herb blend — Add 1/4 teaspoon smoked paprika and a pinch of cayenne to the spice mix for warmth.
• Lemon-herb twist — Toss in 1 tablespoon lemon zest and squeeze fresh lemon over everything after roasting.
• Fall fruit addition — Add a chopped apple or pear to the vegetables for a sweet-tart contrast.

How Do I Store High Protein Thanksgiving Sheet Pan Dinner (Turkey Tenderloin) Leftovers?

A little care here keeps the turkey from drying out on day two.

• Airtight container — Refrigerate the sliced turkey and vegetables together for up to 4 days.
• Separate the components — Keep turkey in its own container if you can, so it doesn’t soak up vegetable moisture.
• Freezer-safe containers — Freeze leftovers for up to 3 months; slice the turkey first so portions thaw quickly.
• Spoon over pan juices — A drizzle of the reserved juices before storing keeps the meat moist.
• Cool before sealing — Let everything come to room temperature first, then refrigerate within two hours of cooking.

How Do I Reheat High Protein Thanksgiving Sheet Pan Dinner (Turkey Tenderloin) Leftovers?

Reheating can make or break leftover turkey, so here’s how to keep it tender.

• Oven method — Reheat at 350°F (175°C) for 10-15 minutes, until warmed through. Best for keeping the vegetables crisp.
• Microwave method — Cover and heat in 1-minute intervals until hot. Fast, though the vegetables soften a bit.
• Air fryer method — 350°F for 5-7 minutes works well for the turkey and firmer vegetables.
• Stovetop method — Warm the turkey in a covered skillet over medium-low heat with a splash of water to prevent drying.

FAQs

Can I freeze High Protein Thanksgiving Sheet Pan Dinner (Turkey Tenderloin)?

Yes, it freezes well for up to 3 months. Slice the turkey and pack it with the vegetables in a freezer-safe container. Thaw overnight in the fridge before reheating.

How long does High Protein Thanksgiving Sheet Pan Dinner (Turkey Tenderloin) last in the fridge?

Up to 4 days in an airtight container. I find it tastes best within the first two days, when the turkey is still at its juiciest.

Can I use chicken instead of turkey tenderloin?

Absolutely. Boneless skinless chicken breasts work, though they’re thicker, so add 5-10 minutes of cook time. Just check that the internal temperature reaches 165°F either way.

Why did my vegetables come out soggy?

Almost always crowding or excess moisture. Spread everything in a single layer, dry your vegetables thoroughly, and use two pans if needed.

How do I keep the turkey from drying out?

Pull it at exactly 165°F and let it rest 5-10 minutes before slicing. Those two habits are the difference between juicy and sawdust.

Can I prep this ahead of time?

Yes. Chop the vegetables and mix the spice blend up to a day ahead, storing everything in the fridge. Toss and roast when you’re ready to eat.
