Ingredients for chicken tenderloin potato
Fresh chicken, tender potatoes, and herbed butter—just five key ingredients for restaurant-quality weeknight magic.
| Ingredient | Amount | Notes |
|---|---|---|
| Chicken Tenderloins 🍗 | 1 ½ lb | Fresh, trimmed of fat and silverskin |
| Baby Potatoes 🥔 | 2 lbs | Yukon Gold preferred, halved |
| Unsalted Butter 🧈 | ½ cup | Cold, cut into chunks |
| Garlic Cloves 🧄 | 6 cloves | Fresh, minced for butter |
| Fresh Rosemary 🌿 | ¼ cup | Finely chopped, stems removed |
| Diamond Crystal Kosher Salt 🧂 | 1 ½ tbsp | For seasoning and roasting |
| Ground Black Pepper 🌶️ | 1 tsp | Freshly cracked |
| Extra-Virgin Olive Oil 🫒 | 2 tbsp | For searing chicken |
| All-Purpose Flour 🌾 | ¼ cup | For dredging chicken |
| Fresh Thyme Leaves 🌿 | ½ tsp | Chopped, for garnish |
| Lemon Zest 🍋 | 1 tsp | From 1 medium lemon |
The chicken tenderloins are the star here. Buy them fresh-cut from your local butcher—they’ll be more tender than pre-packaged. Look for plump, pink pieces with minimal fat. Costco or Whole Foods usually carry them pre-trimmed, but if you’re doing it yourself, trim any silver skin or fat for that perfect crisp. Baby potatoes are non-negotiable for this recipe—their small size ensures even cooking. Yukon Golds are ideal for their buttery texture, but red potatoes work too if that’s what’s on hand. Halve them before roasting so they crisp up nicely.
No fresh rosemary? Dried works at one-third the amount, but trust me, fresh is worth the trip to the grocery store. Running low on butter? Ghee or duck fat adds a luxurious twist. The flour is just for dredging—don’t skip it, though. It creates that golden crust on the chicken. If you’re short on time, panko breadcrumbs give extra crunch. For the garlic, roast it first—toss minced cloves with olive oil, roast at 400°F for 10 minutes, then mix into the butter. Game changer.
This dish reheats beautifully—just pop it in a 350°F oven for 10-15 minutes to crisp everything up again. Store leftovers in an airtight container for up to 3 days, but honestly, it’s best fresh. The herbed butter? Make extra—it’s perfect on toast or steak later. Freeze any leftover butter in an ice cube tray for single-serving portions. And if you’re prepping ahead, par-cook the potatoes (boil 5 minutes, then drain) the night before to cut down on active time.
Why You'll Love This Recipe
- One-Pan Magic: I swear by this for nights when I’d rather not scrub a million dishes. Toss everything on a sheet pan—tenderloins, potatoes, garlic, rosemary—and let the oven do the work. The butter pools around the edges while the chicken gets perfectly golden, and honestly? That’s my kind of effortless.
- Herb-Infused Crunch: Between the rosemary’s piney kick and the garlic’s slow caramelization, this isn’t just "good"—it’s the kind of flavor that lingers. The potatoes develop a crispy skin while staying fluffy inside, and that melt-in-your-mouth chicken? It’s the kind of bite that makes people ask for seconds before dessert even arrives.
- Weeknight Workhorse: This feeds four in 30 minutes but scales up for game days or family dinners. Double the batch, reheat the next day, or pack it for lunch—it’s that reliable. My kids even eat it cold, and that’s saying something.
- Budget-Friendly Luxury: Tenderloins cost less than breasts but feel like a fancy meal. Baby potatoes are cheaper than Yukon golds, and a stick of butter stretches across two servings. It’s the kind of dish that feels indulgent without breaking the bank—or my willpower to order takeout.
Step-by-step instructions for crispy chicken tenderloin and potatoes
Here's how to achieve perfectly crispy chicken with tender, herbed potatoes every time.
Prepare the Chicken for Crispy Perfection
Pat the 1.5 lb chicken tenderloins completely dry with paper towels—this is crucial for achieving that golden crust. Season both sides generously with 1.5 tbsp diamond crystal kosher salt and 1 tsp ground black pepper, pressing the seasoning into the meat so it adheres well. Let them sit at room temperature for 15 minutes while you prep the potatoes.
Working quickly, dredge each tenderloin in 0.25 cup all-purpose flour, shaking off any excess. The flour creates a light crust that will crisp beautifully when seared. Place the floured tenderloins on a wire rack set over a baking sheet—this allows air to circulate underneath for even cooking.
Roast the Potatoes with Herbed Butter
Preheat your oven to 425°F. Toss the 2 lbs baby potatoes (halved) with 2 tbsp extra-virgin olive oil, 1 tsp diamond crystal kosher salt, and 0.5 tsp fresh thyme leaves. Spread them evenly on a separate baking sheet, cut-side down, to maximize surface area for crisping.
In a small bowl, combine the 0.5 cup unsalted butter (cold, in chunks), 6 minced garlic cloves, 0.25 cup finely chopped fresh rosemary, 1 tsp lemon zest, and an additional 0.5 tsp diamond crystal kosher salt. Spread this herbed butter mixture evenly over the potatoes, making sure each piece gets coated. Roast both the potatoes and chicken together for 25 minutes—this shared cooking time ensures everything finishes at the same temperature.
Sear the Chicken for Maximum Crispiness
After 25 minutes, remove the potatoes from the oven and increase the heat to 450°F. Carefully transfer the chicken tenderloins to a cold skillet (this prevents overheating) and sear over medium-high heat for 3-4 minutes per side until they reach an internal temperature of 165°F and develop deep golden-brown crusts. The potatoes can stay in the oven while you finish the chicken.
Here's the thing—don't rush the searing. You'll know it's ready when the crust is deep golden brown and the chicken releases easily from the skillet. The residual heat from the oven will keep the potatoes warm while you finish the chicken.
Finish and Rest for Juicy Results
Return the seared chicken to the baking sheet with the potatoes and transfer everything back to the oven for 5-7 minutes to ensure the chicken reaches 165°F throughout. The potatoes should now be tender when pierced with a fork and have crispy edges from the herbed butter.
Let the chicken rest for 5 minutes before serving—this crucial step allows the juices to redistribute, ensuring each bite is moist and flavorful. The potatoes can be served immediately from the baking sheet, their crispy edges and herbed butter making them irresistible.
Pro Tips For Making Chicken Tenderloin Potato
- Sear Chicken First: Hit the tenderloins with a screaming-hot pan for 2-3 minutes per side before adding anything else—this locks in juices and builds flavor. I used to skip this and ended up with dry, bland chicken that needed extra sauce to rescue it.
- Parboil Potatoes: Toss baby potatoes in boiling water for 5 minutes first, then finish them in the oven or pan with the chicken. This guarantees even cooking and prevents them from turning to mush when they hit the heat later.
- Don’t Overcrowd the Pan: Cook the chicken in batches if needed—overcrowding steams the meat instead of browning it. I learned this after serving dinner with chicken that looked sad and gray instead of golden. Trust me, the pan will thank you.
- Mince Garlic Fine: Use a knife instead of a press for garlic—tiny, even pieces toast faster and infuse the butter without burning. I was skeptical until I tried it, and now I can’t go back to the clumpy mess from a press.
Storing and reheating this dish
Refrigerator Storage
Store leftovers in an airtight container with the chicken and potatoes separated to maintain crispiness. I use glass Pyrex containers because they keep food fresh longer than plastic. Keep them refrigerated at 40°F or below for up to 3 days—though honestly, this dish tastes best fresh.
The herbed butter can be stored separately in a small container to prevent sogginess. 🧊
Freezer-Friendly Tips
For longer storage, freeze the chicken and potatoes separately in single-serving portions. Wrap each tenderloin tightly in plastic wrap, then place in a freezer bag with parchment paper between layers to prevent sticking.
Potatoes can be frozen raw (halved) in a single layer on a tray before bagging. Both will keep for up to 3 months—just thaw overnight in the fridge before reheating. 🥶
Oven Reheating Method
My preferred way to revive this dish is by reheating in a 425°F oven for 10-15 minutes. Place chicken and potatoes on a baking sheet with a splash of water or broth to restore moisture.
The high heat helps recreate that crispy exterior. For extra flavor, brush the chicken with a little melted butter before reheating. 🔥
Microwave Shortcut
For quick meals, use the microwave on 50% power for 1-2 minutes, stirring halfway. Cover with a damp paper towel to trap steam and prevent drying.
Add a pat of herbed butter after reheating to restore richness. This method works best for potatoes—chicken may lose some crispiness but stays tender. ⏱️
Make-Ahead Prep
Save time by par-cooking the potatoes the night before: boil them for 5 minutes, then drain and refrigerate. When ready to cook, simply toss with oil and herbs, then roast as directed.
The chicken can be seasoned and refrigerated overnight—just bring it to room temperature before cooking. This cuts active cooking time by 30 minutes. ⏰
Herbed Butter Hack
Make extra herbed butter and freeze it in ice cube trays. Pop out single cubes and store in a freezer bag for future use on toast, steak, or corn on the cob.
Each cube is perfect for finishing dishes—just let it soften slightly before using. This keeps your butter from spoiling and adds flavor to any meal. 🧈

Frequently asked questions
Can I use regular potatoes instead of baby potatoes?
Yes, but you'll need to adjust the cooking time. Cut larger potatoes into 1-inch chunks and roast them for 5-10 minutes longer at 425°F to ensure they're fully tender. Baby potatoes cook faster and develop better crispy edges, but larger varieties still work well with this method.
What's the best way to keep the chicken tenderloins juicy?
Never skip the 5-minute rest after cooking! This allows juices to redistribute. Also, use a meat thermometer to check for 165°F internal temperature—overcooking dries out the meat. Brining the chicken for 30 minutes in salted water (1/4 cup salt per 4 cups water) before cooking adds extra moisture.
Can I make this recipe without flour?
For a gluten-free version, skip the flour and either:
- Pat the chicken dry and sear directly, or
- Use cornstarch or almond flour instead. You'll get a slightly different texture, but the flavor remains excellent. The herbed butter still works perfectly with either method.
How do I prevent the potatoes from turning mushy?
Halving the potatoes (rather than quartering) and roasting cut-side down maximizes surface area for crisping. Don't overcrowd the baking sheet—leave 1-inch gaps between pieces. Also, increase oven temp to 450°F for the last 10 minutes of cooking to boost browning.
What are good sides to serve with this dish?
This hearty chicken and potato combo pairs beautifully with:
- A simple mixed greens salad with lemon vinaigrette,
- steamed asparagus with lemon zest, or
- roasted Brussels sprouts with bacon. For a complete meal, add a slice of crusty bread to soak up the herbed butter.
