Today’s post on how to roast peppers in a steam oven comes to you as the result of a happy kitchen accident.

A little while back, I needed to roast a few whole red peppers to make a dip, but my regular oven, where I usually grill them, already had something cooking in it.

Lucky for me, I have two ovens, so I figured I’d whack them into the combi steam, using a very hot convection setting with no steam.

I just needed to get the peppers a bit blistered and blackened all over so I could peel off the skins. The more I thought about it, though, the more I thought surely it couldn’t hurt to use the combi steam setting to speed up the process.

Seeing as we’re here, talking about this, you can probably guess what happened next: it worked unbelievably well. The steam didn’t actually speed things up all that much, but it did have a huge benefit over roasted peppers done in a regular oven or over an open flame: the skins peeled away more easily than I’ve ever had them do.

In much the same way as a quick steam or a blanch in boiling water makes fruit and vegetable skins easy to remove, the moisture here has the same effect on roasted peppers, separating skin from flesh with little effort on your part.

Will you get the same charred, smoky effect from your steam oven as you do roasting peppers over a naked flame? Not quite. But if you want a quick and relatively mess-free alternative to the traditional grilling method, I’d really encourage you to try this.

What can you do with roasted peppers?

If you haven’t used roasted peppers much as an ingredient before, you might wonder if it’s worth roasting your own when you could just buy a jar of pre-roasted ones. I’d argue it is, because the taste and texture is so much better. Any leftovers will keep, packed under a layer of olive oil in the refrigerator for about two weeks, and you can use them in all sorts of dishes to add a quick burst of flavour and colour.

I’ll be back in a couple of days with a recipe for a gorgeous Syrian roasted pepper and walnut dip called Muhammara (or Muhmmara, or Mouhammara, depending on who you ask), but here are some other things I like to do with roasted peppers:

·       Slice or tear up for pizza topping

·       Slice and cook into omelettes or scrambled eggs

·       Slice or puree into a pasta sauce

·       Stir into paella

·       Use as a sandwich or wrap filling

·       Toss through salads

·       Blend with cream cheese for a speedy dip

·       Mix with vegetable stock, a little cream and basil pesto to make a 10-minute soup

I hope that’s given you a few ideas to start with, and that you’ll try roasting peppers in your steam oven! Happy steam oven cooking and I’ll see you here again soon.

How to Roast Peppers in a Steam Oven

Steam oven roasted peppers, or capsicums, are speedy and so simple. The skins blister and peel away easily and there's no turning over a flame to mess about with.
Cook Time20 minutes
Total Time20 minutes
Course: Appetizer, Side Dish
Cuisine: Mediterranean, Mexican, Middle Eastern, Spanish
Keyword: how to roast peppers, how to roast peppers in a steam oven
Servings: 2 peppers


  • 2 red bell peppers you can use whatever colour you like but red is the most traditional


  • Preheat oven as hot as it’ll go, using the combi steam setting. Mine gets to 230°C/450°F – if yours is different you’ll just want to scale your cooking time up or down a bit to suit. If you have variable steam settings, choose 60%. If not, doesn’t matter! Just choose combi steam at the hottest temperature and let the oven figure out the humidity.
  • Place the peppers into a small pan (I love my pictured 1/3-size stainless steel gastronorm pan for this). If you’re roasting a larger quantity, use a larger pan. The idea is to have the peppers fitting fairly snug in the pan, but with a little room for airflow between each one.
  • Once the oven is hot, place the pan in the oven and cook the peppers, turning once or twice, until the flesh is softened and they’re starting to get black blisters on the skin. In my oven this takes anywhere from 15 to 25 minutes.
  • Remove the cooked peppers from oven and allow to cool until you can handle them, then slip the skins off and scrape the seeds out from the middle. Carefully pulling out the stem usually brings most of the seeds along with it, leaving just a few to be scraped out with the back of a knife. You might be tempted to wash the seeds off the flesh, because they can be a bit slippery to get rid of – don’t do this, as you’ll lose all the fabulous flavour and render your roasted peppers watery and bland.
  • If you’d like to store your roasted peppers, they’ll keep, covered, in a container in the fridge for a couple of days. To store them for longer, pack them tightly into a jar and completely cover the top with a layer of olive oil before putting the lid on. They’ll keep like this for a couple of weeks.


  1. This can be scaled up to cook as many peppers as you like, and should take around the same time.
