Side Dishes
Recreating Trader Joe's signature roasted potatoes with peppers and onions at home delivers that same smoky, charred perfection without the store-bought shortcut. The secret lies in high-heat roasting and a precise blend of olive oil, garlic powder, and smoked paprika—just like their version, but with restaurant-quality control.
I've perfected this method after years of testing, ensuring crispy edges and tender centers every time.
This recipe requires just 15 minutes of prep and 40 minutes in the oven, making it ideal for weeknight dinners or holiday sides. The combination of baby potatoes, bell peppers, and onions creates a textural contrast that's impossible to resist—crispy potatoes, tender peppers, and caramelized onions all roasted together.

Let's get started on this foolproof, restaurant-worthy side dish that's easier than you'd expect.
Ingredients for trader joe's roasted potatoes with peppers and onions
Pantry staples and fresh veggies—this roast delivers smoky, charred perfection like Trader Joe's but better.
| Ingredient | Amount | Notes |
|---|---|---|
| Baby Potatoes 🥔 | 1 ½ lb | Yukon gold or red preferred, halved |
| Red Bell Peppers 🍅 | 2 whole | Seeded, cut into 1-inch pieces |
| Yellow Onions 🧅 | 1 whole | Cut into 1-inch chunks |
| Extra-Virgin Olive Oil 🫒 | ½ cup | High quality, fruity |
| Smoked Paprika 🌶️ | 1 tbsp | For authentic smoky flavor |
| Garlic Powder 🧄 | 1 tsp | Freshly ground preferred |
| Ground Black Pepper 🌶️ | ½ tsp | Freshly cracked |
| Diamond Crystal Kosher Salt 🧂 | 1 ½ tsp | For even seasoning |
| Fresh Rosemary 🌿 | ¼ cup | Chopped, finely |
| Fresh Thyme 🌿 | ¼ cup | Leaves only, chopped |
| Red Wine Vinegar 🍷 | 1 tbsp | For brightness |
| Honey 🍯 | 1 tbsp | Light amber preferred |
The potatoes are the star, so Yukon gold or red are your best bets—they hold up perfectly while roasting. Trader Joe's has pre-washed baby potatoes if you're short on time, but any uniform size works. For the peppers, red or yellow bell peppers add sweetness, but green works too if that's what you've got. The onions? Yellow or red both caramelize beautifully—just make sure they're cut into even-sized chunks so they cook at the same rate. Fresh herbs matter here: Trader Joe's sells pre-chopped rosemary and thyme, but I always grab whole sprigs and chop them myself for better flavor.
No smoked paprika? Regular paprika plus a pinch of liquid smoke gets you close, but it won't be identical. Short on fresh herbs? Dried rosemary and thyme at one-third the amount work in a pinch, but fresh is worth it. The red wine vinegar adds brightness—substitute lemon juice if that's what you've got. Honey can be swapped for maple syrup, but it won't have the same floral notes. For the olive oil, any extra-virgin works, but avoid cheap brands—they can make the dish taste bitter. The key is tossing everything with enough oil so the seasoning sticks, but not so much that it gets soggy.
This roast tastes even better the next day—reheat at 350°F for 10 minutes to crisp it up again. Store leftovers in an airtight container for up to 5 days, though I usually eat it all in one sitting. For meal prep, roast a bigger batch and portion it into containers. The flavors meld even more overnight, making it perfect for lunches. If you're serving a crowd, double the recipe—it scales beautifully, and the high-heat method ensures everything cooks evenly.

Step-by-step instructions for smoky roasted potatoes, peppers, and onions
Here's how to achieve that perfect balance of crispy edges and tender centers with deeply charred vegetables.
Prep and Parboil the Baby Potatoes
Start by halving the 1.5 lb baby potatoes—leave the skins on for texture, but cut them evenly so they cook at the same rate. Place them in a pot of cold, salted water (about 1 tablespoon of the diamond crystal kosher salt) and bring to a boil over medium-high heat. Once boiling, reduce to a gentle simmer and cook for exactly 8 minutes—this partial cooking ensures they finish perfectly tender in the oven without turning mushy.
Drain the potatoes immediately and transfer them to a large bowl. While they're still warm, toss them with the 0.5 cup extra-virgin olive oil, 1 tablespoon smoked paprika, 1 teaspoon garlic powder, and 0.5 teaspoon ground black pepper. The oil should coat every surface evenly—this is where the magic happens for that crispy skin. Let them sit for 5 minutes while you prep the vegetables, allowing the seasoning to penetrate slightly.
Prep and Season the Vegetables
Cut the 2 whole red bell peppers into 1-inch pieces, removing seeds and membranes as you go. Dice the 1 whole yellow onion into similarly sized 1-inch chunks—uniform pieces ensure even cooking. In a separate bowl, whisk together the 0.25 cup finely chopped fresh rosemary, 0.25 cup chopped fresh thyme leaves, 1 tablespoon red wine vinegar, and 1 tablespoon honey. This bright, herby dressing will caramelize beautifully while roasting.
Toss the peppers and onions with the dressing, making sure every piece gets coated. The vinegar and honey will create a sticky glaze that enhances charring, while the herbs add depth. Let the vegetables sit for 10 minutes—they'll absorb the flavors and soften slightly, which prevents them from drying out in the oven.
Roast Until Caramelized and Crispy
Preheat your oven to 425°F. Spread the seasoned baby potatoes in a single even layer on two rimmed baking sheets, leaving about 1 inch between each piece. This spacing is crucial—it prevents steaming and promotes crispy edges. Roast for 25 minutes, then carefully flip each potato with a spatula and add the tossed peppers and onions to the pans, spreading them evenly.
Return to the oven and roast for another 20-25 minutes, until the potatoes are golden brown and crispy in spots, and the peppers and onions are deeply charred with caramelized edges. The potatoes should be tender when pierced with a fork, and the vegetables should have that perfect balance of soft centers and crispy outsides. If the edges aren't dark enough after 20 minutes, give them another 5 minutes—they'll keep developing flavor as they cool.
Finish with Fresh Herbs and Serve
Remove the pans from the oven and let everything rest for 5 minutes—this allows the juices to redistribute and the vegetables to finish steaming slightly. Before serving, give the roasted vegetables a final toss with any accumulated juices in the pans. The residual heat will help everything meld together beautifully.
Garnish with extra chopped fresh rosemary and thyme if desired, and serve immediately while still warm. The potatoes should be crispy on the outside with fluffy interiors, while the peppers and onions should be tender with caramelized, slightly charred edges. This dish pairs perfectly with grilled meats or as a standalone vegetarian main—just be ready to clear your plate quickly!
Pro Tips For Making Trader Joe'S Roasted Potatoes With Peppers And Onions
- CUT POTATOES IN HALF: Baby potatoes need to be halved—no quarters, no whole—so they cook evenly and develop that crispy edge. I used to skip this and ended up with some undercooked centers and others turning to mush. Halving also lets the oil penetrate better, which means better browning.
- CHAR THE ONIONS FIRST: Slice onions thin and cook them in a dry pan over medium-high heat for 3-4 minutes until they start to brown. This deepens their flavor way more than just roasting them raw. After that, toss them with the potatoes—just don’t overcrowd the pan, or they’ll steam instead of caramelize.
- SALT THE POTATOES BEFORE ROASTING: Toss the halved potatoes with oil and salt before they hit the oven—at least 15 minutes ahead if possible. This ensures the salt penetrates and crisps up the edges instead of just sitting on top. I learned this the hard way when my roasted potatoes tasted bland no matter how much I salted after.
- USE A MIX OF OILS: Extra-virgin olive oil is great, but add a splash of neutral oil like avocado or grapeseed—about 1 tablespoon—to help the potatoes brown faster and more evenly. The olive oil adds flavor, while the neutral oil prevents burning. It’s a small tweak, but it makes a real difference in texture.
Essential equipment for trader joe's roasted potatoes with peppers and onions
Oven Essentials
Your oven is the star of this recipe—425°F is non-negotiable for that signature charred flavor. I recommend a convection oven if yours has one, as it circulates heat more evenly and speeds up browning.
If you're using a standard oven, place the baking sheets on the middle rack for consistent heat distribution. For even crispier results, I use two heavy-duty rimmed baking sheets—they handle high heat better than glass or thin metal pans. 🌡️
Potato Prep Tools
A sharp chef's knife and cutting board are essential for even potato halves. I find a mandoline helpful if you're prepping a large batch, but it's not required. For the 8-minute parboil, use a medium-sized pot with enough water to cover the potatoes by at least 1 inch.
A fine-mesh strainer makes draining quick and easy—no soggy potatoes here!
Seasoning Must-Haves
Invest in high-quality smoked paprika—I swear by Penzeys Spices for their deep, consistent smokiness. A garlic press saves time when mincing fresh garlic for the seasoning blend. For measuring, a small digital scale ensures precision with spices like garlic powder and black pepper.
Don't skimp on extra-virgin olive oil—California Olive Ranch is my go-to for its fruity, buttery notes that elevate the dish.
Herb Handling
Fresh herbs make all the difference, so grab whole rosemary and thyme sprigs from your grocery store's produce section—they're usually fresher than pre-chopped. A pair of kitchen shears makes quick work of chopping them finely.
Store-bought pre-chopped herbs work in a pinch, but I find fresh always tastes better. For the red wine vinegar and honey, use small squeeze bottles to measure precisely—no guesswork here!
Serving Gear
Serve this dish straight from the baking sheets for maximum crispiness, or transfer to a large serving platter. A tongs makes tossing the veggies effortless before serving. For garnish, I like to use a small offset spatula to sprinkle extra herbs neatly.
If you're prepping ahead, airtight glass containers keep everything fresh for up to 5 days—just reheat at 350°F for 10 minutes to restore crispiness. 🍽️
Budget-Friendly Swaps
No fancy tools? A sharp paring knife works for chopping veggies, and a measuring spoon set covers all your spice needs. For olive oil, store-brand extra-virgin is fine—just avoid anything labeled "light" or "pure." Skip the mandoline and use a serrated knife for even potato halves.
The key is even heat distribution, so if your oven runs hot, check the potatoes at 20 minutes instead of waiting the full time.

Frequently asked questions
Why do the potatoes need to be parboiled before roasting?
The 8-minute parboil ensures the potatoes finish perfectly tender in the oven without turning mushy or dry. This step also helps the seasoning stick better during the high-heat roast, giving you that ideal crispy exterior with fluffy interiors that Trader Joe's version is known for.
Can I use regular potatoes instead of baby potatoes?
Yes, but you'll need to cut them into 1-inch pieces first. Regular potatoes take longer to roast evenly, so increase the total roasting time by 10-15 minutes and check for doneness at 35 minutes. Baby potatoes are ideal because their small size ensures uniform cooking and maximum crispiness.
What if my oven runs hot and the potatoes burn before they're done?
If your oven runs hot, reduce the temperature to 400°F and add 5-10 minutes to the roasting time. Use an oven thermometer to verify your oven's actual temperature—many home ovens run 25-50°F hotter than set. For extra insurance, spread the potatoes on a single layer with even spacing between pieces.
How can I make this dish spicier?
Add ½ teaspoon cayenne pepper or 1 teaspoon chili flakes to the potato seasoning, or toss the roasted veggies with 1 tablespoon hot sauce before serving. For smoky heat, increase the smoked paprika to 2 tablespoons and add ½ teaspoon chipotle powder to the dressing.
Can I make this ahead of time for a meal prep?
Roast the dish as directed, then store in an airtight container for up to 5 days. To restore crispiness, reheat at 350°F for 10 minutes or until warmed through. For best texture, serve within 2 days of roasting—freshness keeps the potatoes crispy.
