Prep and Cook Time

• Preparation: 10 minutes
• Cooking: 25 minutes
• Total Time: 35 minutes

Yield

Serves 4 as a side dish or ingredient base.

Difficulty Level

Easy

Ingredients

• 3 medium bell peppers (assorted colors: red, yellow, orange), cored and sliced into strips
• 2 large sweet onions, peeled and cut into thick wedges
• 3 tablespoons extra virgin olive oil
• 1 teaspoon smoked paprika
• 1 teaspoon garlic powder
• ½ teaspoon dried oregano
• Salt and freshly ground black pepper, to taste
• 1 tablespoon balsamic vinegar (optional, for finishing)

Instructions

1. Preheat the oven to 425°F (220°C). Line a large baking sheet with parchment paper or a silicone mat for easy cleanup.
2. Prepare your vegetables: Place the sliced peppers and onion wedges in a large mixing bowl. Drizzle with the olive oil and gently toss to coat all pieces evenly.
3. Add your seasoning blend: Sprinkle the smoked paprika, garlic powder, oregano, salt, and pepper over the peppers and onions. Toss again to distribute the spices well.
4. Arrange the veggies in a single layer on the baking sheet. For even caramelization, avoid overcrowding. Give some space between pieces.
5. Roast in the oven for 20 to 25 minutes, turning halfway through with a spatula. Roast until the edges are slightly charred, and the vegetables are tender and glossy.
6. Finish with a splash of balsamic vinegar (optional) immediately after removing from the oven to add a tangy sweetness that heightens their flavor complexity.
7. Serve warm or at room temperature, garnished with fresh herbs like chopped parsley or thyme for a pop of color and brightness.

Tips for Success

• Use a mix of brightly colored bell peppers for a visually stunning plate. Their slight color differences also provide varied sweetness levels.
• If you prefer a smokier taste, add a pinch of chipotle powder or smoked sea salt to your seasoning blend.
• Make sure the peppers and onions are cut into uniform sizes for even roasting-size affects cooking time!
• For a make-ahead option, store cooled roasted peppers and onions in an airtight container in the fridge for up to 4 days. Reheat gently or use cold as a salad topping.
• Experiment with other complementary herbs like rosemary or thyme based on your meal’s theme.

Q3: What kinds of peppers and onions work best for roasting?
A3: Bell peppers (red, yellow, orange) are stars in the roasting spotlight because of their natural sweetness and thick flesh that softens beautifully. For onions, sweet varieties like Vidalia or Walla Walla shine the brightest, as roasting amplifies their sugars and tames their bite. But experiment!

Q4: How do I prepare peppers and onions for roasting to get the best flavor?
A4: Simple prep is key. Slice them evenly to ensure uniform cooking-about ¼ to ½ inch thick works well. Toss with olive oil, a pinch of salt, and black pepper to enhance natural flavors. For a twist, add herbs like thyme or oregano before roasting. Spread them out in a single layer on a baking sheet to let caramelization blossom.

Q5: What temperature and timing is ideal for roasting these vegetables?
A5: Preheat your oven to around 425°F (220°C). Roast the peppers and onions for 20 to 30 minutes, stirring halfway through to encourage even browning. Keep an eye on them towards the end; you want them tender and caramelized, not burnt.

Q6: Can oven-roasted peppers and onions be stored for later use?
A6: Absolutely! Once cooled, store them in an airtight container in the fridge for up to 4 days. They’re perfect for quick meal upgrades or snacks. You can also freeze them for longer shelf life-just thaw and reheat gently.

Q7: Any creative serving ideas beyond the usual?
A7: Definitely! Spread them on warm focaccia with goat cheese for a rustic appetizer, fold into frittatas or savory crepes, or blend with cream cheese for a smoky, sweet dip.
