How to Make Roasted Potatoes with Onions and Peppers Recipe
Step 1: Prepare the Vegetables
Start by washing and peeling your russet potatoes, then cut them into evenly sized cubes to ensure they cook uniformly. Roughly chop the bell peppers and yellow onion into bite-sized pieces — don’t worry about perfection here; rustic shapes roast up beautifully. Mince the garlic finely so it will distribute flavor evenly among the veggies.
Step 2: Toss with Oil, Butter, and Seasonings
In a large bowl, combine the potatoes, bell peppers, onion, and minced garlic. Drizzle olive oil and melted butter over the mix, then sprinkle sea salt, dried rosemary, and coarse ground pepper. Toss everything until each piece is lightly coated — this ensures all those glorious flavors will roast into the potatoes and vegetables.
Step 3: Arrange and Roast
Spread the mixture out in a single layer on a large baking sheet, avoiding overcrowding to allow the edges to crisp up nicely. Place in a preheated oven at 425°F (220°C) and roast for around 40 to 50 minutes, stirring every 15 minutes to promote even browning. The potatoes should become golden and crispy while the peppers and onions turn tender and caramelized.
Step 4: Finishing Touches
Once roasted to your desired crispness, remove the potatoes and vegetables from the oven. Sprinkle the fresh parsley over the top to add color and a fresh herby zing that complements the roasted flavors perfectly. Give everything a gentle toss before serving.
How to Serve Roasted Potatoes with Onions and Peppers Recipe
Garnishes
To make this dish shine even more, consider garnishing with a light sprinkle of smoked paprika or a squeeze of fresh lemon juice to add a lively contrast. A bit of crumbled feta or grated Parmesan will also boost the flavor and richness if you’re feeling indulgent.
Side Dishes
This Roasted Potatoes with Onions and Peppers Recipe works beautifully alongside roasted chicken, grilled steak, or even a hearty vegetable stew. They also pair well with fresh green salads or steamed greens to balance the meal with a little lightness and crunch.
Creative Ways to Present
For a fun twist, turn this dish into a loaded baked potato topping or mix it into a warm grain bowl with quinoa and arugula. Serving it in rustic cast iron skillets also adds charm to your presentation, perfect for casual family dinners or festive gatherings.
Make Ahead and Storage
Storing Leftovers
Leftover roasted potatoes with onions and peppers keep well in an airtight container in the refrigerator for up to 4 days. This makes it easy to enjoy this flavorful side even later in the week without losing any of its charm.
Freezing
You can freeze this dish, though it’s best to slightly undercook the potatoes initially to avoid a mushy texture when reheated. Store in a freezer-safe container for up to 2 months, making it a handy meal prep option.
Reheating
For the best results, reheat leftovers in an oven or air fryer to regain their crispiness. Avoid microwaving if possible, as it can lead to soggy potatoes and peppers, which takes away from the delightful texture we aim for.
FAQs
Can I use other types of potatoes for this recipe?
Absolutely! While russet potatoes are ideal due to their starchy quality that crisps nicely, Yukon Gold or red potatoes can also work well if you prefer a waxier texture. Just keep in mind the roasting times might vary slightly.
Is there a way to make this recipe vegan?
Yes! Simply substitute the butter with extra olive oil or a plant-based spread to keep the dish completely vegan without sacrificing flavor. The olive oil will maintain the crispy texture beautifully.
How do I know when the potatoes are done roasting?
Check for golden brown edges and a tender interior by piercing the potatoes with a fork. They should feel soft inside and have a crispy exterior. Stirring occasionally also helps even cooking and caramelization.
Can I add other vegetables to this dish?
Definitely! Feel free to toss in chunks of zucchini, cherry tomatoes, or mushrooms for added variety. Just consider their cooking times to ensure everything finishes roasting simultaneously.
What is the best way to make this recipe more flavorful?
Fresh herbs are game changers: add thyme, oregano, or even fresh rosemary alongside parsley. Using quality olive oil and seasoning generously with sea salt and freshly ground pepper also brings the flavors to life.
