How do you roast peppers in the oven Jamie Oliver?

Roasted peppers are a delicious and versatile ingredient that can be used in many dishes. Peppers are often roasted in the oven, which allows the skin to char and the flavors to become concentrated. TV chef Jamie Oliver has shared his simple method for how to roast peppers in the oven for perfect results every time.

Why Roast Peppers?

Roasting peppers accomplishes a few things:

– It chars and blackens the skin, which makes it easy to remove. The charred skin can give an undesirable bitter flavor.

– It collapses the waxy inner walls and membranes, giving the pepper a softer, silky texture.

– It concentrates the flavor, bringing out the natural sweetness.

– It allows you to draw out moisture, resulting in intensely flavored roasted pepper pieces.

– It caramelizes some of the sugars inside, adding complexity.

So in short, roasting transforms the flavors and texture of peppers into something sweeter, softer, and bolder.

Jamie Oliver’s Method

Jamie Oliver recommends this simple approach to roast peppers in the oven:

1. Preheat oven to 425°F (220°C).

2. Place whole pepper(s) on a baking tray lined with parchment paper.

3. Roast for 20-30 minutes, turning occasionally, until charred all over.

4. Transfer to a bowl, cover with plastic wrap, and let steam for 10-15 minutes.

5. Peel off the skin (it should slide off easily) and remove stems and seeds.

6. Slice, chop or dice the peeled peppers as desired.

Tips for the Best Results

– Use bell peppers or long thin peppers like Hungarian wax or Gypsy peppers. Hot peppers can also be roasted but may need less time.

– Roast peppers whole rather than halved or sliced. It helps them roast evenly.

– Use a rimmed baking sheet lined with parchment for easiest cleanup. The peppers will release moisture.

– Roast at a high heat (400-425°F) to get the skins charred and peppers tender.

– Turn the peppers as they roast. You can use tongs to flip them or rotate the pan. This ensures even charring.

– Let peppers steam after roasting. The steam helps loosen the skins.

– Keep the juices from the roasting pan to add flavor to sauces, stews or vinaigrettes.

Step-By-Step Photo Guide

Here is a step-by-step visual guide to prepping and roasting peppers using Jamie Oliver’s oven method:

Step 1: Prep the peppers. For bell peppers, cut around the stems, remove, and discard seeds and membranes. Leave other types of peppers whole.

Step 2: Place peppers on a parchment-lined baking sheet. Space them apart.

Step 3: Roast peppers at 425°F for 20-30 minutes. Use tongs to flip halfway during roasting.

Step 4: Remove charred peppers from oven and immediately cover with plastic wrap or place in a covered bowl. Let steam for 10-15 minutes.

Step 5: Once cool enough to handle, peel off skins. They should slip off easily after steaming.

Step 6: Slice, chop or dice peppers as desired for your recipe. Enjoy!

What Peppers to Roast

Almost any type of pepper can be roasted in the oven using Jamie Oliver’s method. Here are some of the most common varieties:

Bell Peppers

Preparation Methods

While Jamie focuses on whole roasted peppers, there are a few other preparation methods to consider:


Cutting peppers in half lengthwise before roasting exposes more surface area to caramelize and char. This speeds up cooking time.


Slicing peppers into strips means less time in the oven. Great for quick roasting when prepping fajitas or stir-fries.


Chopping peppers small to roast is perfect for making a delicious roasted pepper salsa.

So in summary, while roasting whole works well, don’t hesitate to halve, slice or chop peppers beforehand for quicker roasting or different end results.

Complimentary Flavors

Roasted peppers pair wonderfully with many ingredients that complement and accentuate their flavors. Some tasty combinations include:

– Garlic: Adds richness and savory depth. Roast garlic cloves alongside peppers.

– Herbs: Basil, oregano, and thyme add fresh flavors. Toss roasted peppers with herbs.

– Spices: Smoked paprika, coriander, and cumin add warmth. Sprinkle on peppers before or after roasting.

– Onions: Red onions, shallots, or scallions balance sweetness. Roast together with peppers.

– Olive Oil: Drizzle over roasted peppers or use in marinades. Provides richness.

– Balsamic Vinegar: Adds tanginess to balance sweetness. Great in marinades or dressings.

– Cheese: Parmesan, feta, mozzarella, or goat cheese contrast nicely with the peppers’ flavors.

– Nuts: Toasted pine nuts, almonds, or hazelnuts pair well with roasted peppers.

– Olives: Kalamatas, green olives, etc. provide brininess. Toss into pepper salads.

So mix and match roasted peppers with herbs, spices, aromatics, oils, cheeses and more to bring out their very best flavors.
