Grilled Peppers and Onions

These grilled peppers and onions are the kind of side dish that can make even the simplest dinner feel more exciting. Sweet, smoky, and full of that lovely charred flavour from the grill, they bring so much colour and warmth to the plate with very little effort. If you are looking for an easy vegetable side that goes with almost anything, this is such a good one to keep in your back pocket. They are simple, vibrant, and the kind of dish that always seems to disappear quickly.

eople here in Australia really do love grilling, and once you start cooking that way more often, you quickly realise you are always looking for new ideas of what else to put on the grill besides the obvious things. Meat is easy to think of. Sausages, chicken, steaks, those come to mind straight away. But vegetables deserve their moment too, and this simple combination of peppers and onions is such a good one.

It is a very easy recipe, yes, but I still wanted to share it because sometimes the simplest combinations are the ones we forget about. You may not immediately think of grilling peppers and onions together, but they work so beautifully. The peppers turn sweet and slightly smoky, the onions soften and caramelise around the edges, and together they make the kind of side dish that goes with almost anything coming off the grill.

My family loves this recipe because it adds so much colour and flavour to the table without creating extra work. It makes a plate feel more generous and more interesting straight away, and I love that. It is one of those dishes that feels relaxed and casual, but still tastes like you made a real effort.

And of course, if you do not have an outdoor grill, you can absolutely make this in a grill pan. It still gives you that lovely charred flavour and works beautifully. So this is not one of those recipes that only belongs to people with big backyards and perfect weather. It is for all of us.

If you are hosting a bigger group, I would definitely suggest making this recipe in batches. Vegetables need space to cook properly. If they are piled too closely together, they are more likely to steam than grill, and you will miss out on those lovely browned edges. A few smaller batches will always give you a better result than one overcrowded one.

If I am making these for a crowd, I like to cook them until nicely tender and lightly charred, then transfer them to a foil tray, cover loosely, and keep them in a warm spot near the grill. They hold their heat well for a while, and the flavours settle in beautifully too. You can even drizzle a little extra olive oil over the top and sprinkle on some fresh parsley just before serving to freshen everything up.

This is exactly the kind of recipe I love for real-life cooking, simple, tasty, flexible, and genuinely useful. Nothing fancy, just good vegetables made even better by a grill, and sometimes that is exactly what a table needs.

Best,

Why you’ll love this recipe

Main ingredients:
This recipe uses simple everyday ingredients; colourful bell peppers, onions, olive oil, garlic, and dried herbs, but together they make a side dish that feels so much more exciting than the ingredient list suggests. It is one of those lovely recipes where a few humble things turn into something really delicious.

How it’s made:
The peppers and onions are tossed with olive oil, garlic, and herbs, then grilled until tender and lightly charred around the edges. It is easy to prepare, easy to cook, and exactly the kind of recipe that works beautifully for both everyday dinners and relaxed entertaining.

Flavours:
These grilled peppers and onions are sweet, smoky, soft, and full of lovely grilled flavour. The peppers become juicy and rich, the onions turn tender and a little caramelised, and together they taste warm, comforting, and full of summer-style goodness. It is the kind of side dish that makes the whole plate feel more colourful, generous, and inviting.

How to serve

Serve these grilled peppers and onions warm, straight from the grill or grill pan, as an easy side dish with chicken, steak, sausages, fish, or anything else you are cooking. I love them next to simple grilled meat with a fresh green salad and maybe some bread or roasted potatoes on the side. They are also lovely spooned into wraps, served over rice, or added to sandwiches and burgers if you have leftovers. It is one of those easy, colourful sides that fits in almost anywhere and makes the whole meal feel more generous.

Tips for Success

The biggest tip here is to cut the peppers and onions into fairly even pieces. That helps everything cook at the same pace and gives you a nicer final dish. If some pieces are tiny and others are very thick, you will end up with a mix of burnt and undercooked vegetables, which is not really the goal.
Do not be shy with the olive oil. You do not need to drown the vegetables, of course, but a good coating helps them soften, char nicely, and pick up all that lovely flavour from the grill. It also helps the seasoning stick properly, which makes a real difference in a simple dish like this.
Make sure the grill is properly heated before the vegetables go on. A hot grill gives you those beautiful charred edges and keeps the vegetables from just sitting there and going limp. If you are using a grill pan, let it get nicely hot first for the same reason.
try not to crowd the grill. This is especially important with vegetables. If they are packed too closely together, they will steam instead of grill, and you will lose that sweet, smoky flavour you are after. If you are cooking for a crowd, batches are definitely the better option.
Keep an eye on the garlic too. Because it is mixed in from the beginning, some little bits may cook faster than the vegetables. Stirring and turning everything now and then helps stop the garlic from catching too much and turning bitter.
And finally, season properly at the end and taste before serving. Peppers and onions become sweeter as they cook, so a final pinch of salt, a little black pepper, or even a small drizzle of olive oil right before serving can make the whole dish taste even better. It is a very simple recipe, but a few careful little steps make it feel truly delicious.

Substitutions & Variations

This is such an easy recipe to play with, which is one of the reasons I love it so much. If you do not have all three colours of bell peppers, just use whatever you have. Red, yellow, orange, or green all work beautifully. Using a mix makes the dish look extra lovely, but even one or two colours will still taste delicious.
For the onions, you can use red onions, yellow onions, or even sweet onions if you prefer a milder flavour. Red onions are especially pretty once grilled, but honestly, they all do the job very well here.
If you do not have fresh garlic, a little garlic powder can work in a pinch. And if you want to change the herbs, you can use Italian seasoning, thyme, or even a little smoked paprika for a warmer, smokier flavour. A pinch of chilli flakes is also lovely if you want a bit of heat.
This recipe also works beautifully with extra vegetables added in. Zucchini, eggplant, mushrooms, or even asparagus can go onto the grill along with the peppers and onions and turn it into more of a mixed grilled vegetable dish.
If you do not have an outdoor grill, you can make this in a grill pan or even roast the vegetables in the oven. They will not taste exactly the same, of course, but they will still be sweet, soft, and full of lovely flavour.
And if you want to dress it up a little before serving, a sprinkle of fresh parsley, crumbled feta, or even a small drizzle of balsamic glaze can be really lovely. It is one of those simple recipes that welcomes little changes very easily and still turns out beautifully.

Storage & Reheating Tips

These grilled peppers and onions store really well, which makes them such a handy side dish to have in the fridge. Once cooled, keep them in an airtight container in the fridge for up to 3 days. They are lovely fresh off the grill, but I have to say, they are also very useful the next day tucked into wraps, sandwiches, salads, or served alongside eggs or grilled meat.

To reheat, warm them gently in a frying pan over medium-low heat until heated through. This is my favourite way because it helps keep a little of that lovely grilled flavour and stops them from turning too soft. You can also reheat them in the microwave if you need something quick, though they will be a little softer that way.

If you are reheating a bigger batch, spreading them out on a tray and warming them in the oven works really well too. A few minutes is usually enough. And if they seem a little dry after being in the fridge, a small drizzle of olive oil brings them right back to life.

One little tip: if you know you are making extra on purpose, do not worry, this is exactly the kind of leftover that never feels boring. They have a very good second life.

How to Use Leftovers

Leftover grilled peppers and onions are the kind of thing that can make the next meal feel much easier. They already have so much flavour, so all the hard work is really done for you.

In a sandwich or wrap:
Layer the peppers and onions into a sandwich, toastie, or wrap with grilled chicken, cheese, hummus, or even just a little mayo or aioli. They are especially good with crusty bread or tucked into a soft wrap for an easy lunch. If you like, warm the vegetables first so everything feels a little more cozy and melty.

With scrambled eggs:
Roughly chop the leftover peppers and onions and warm them in a pan for a minute or two. Then pour in your beaten eggs and cook gently until soft and fluffy. It makes such an easy breakfast or quick lunch, and it instantly feels like more than just plain scrambled eggs.

In a salad:
Let the vegetables cool completely, then toss them through a green salad, grain salad, or pasta salad. They are lovely with feta, olives, cucumber, and a simple lemony dressing. The grilled flavour adds so much interest and makes the salad feel more filling and satisfying.

Over rice or quinoa:
Warm the peppers and onions and spoon them over cooked rice or quinoa. Add grilled chicken, chickpeas, or a fried egg on top if you want to turn it into a full meal. A little spoon of yogurt or hummus on the side is also very good here.

In pasta:
Slice the vegetables a little smaller and stir them through hot cooked pasta with olive oil, garlic, and a sprinkle of Parmesan or feta. You can add grilled chicken or sausage if you want something heartier. It is such an easy dinner and a great way to stretch leftovers into a proper meal.

On pizza or flatbread:
Scatter the peppers and onions over pizza dough, flatbread, or even a pita with cheese and bake until hot and bubbly. They are especially good with mozzarella, goat cheese, or feta. It makes a very easy lunch or relaxed dinner.

With potatoes:
Serve them next to roasted potatoes, stir them through mashed potatoes, or add them to a breakfast hash with potatoes and eggs. The sweet, smoky flavour works so well with potatoes and makes even simple ingredients taste more exciting.

In quesadillas:
Add the leftover peppers and onions to a tortilla with grated cheese, then cook in a pan until golden and crisp on both sides. Slice and serve warm. This one is especially good when you want something quick and everyone is hungry now.
