Over the Summer I’ve had a bit of an eggplant fetish happening. I wish I could say that it was from all the eggplant in my garden but the sad truth is my 3 tiny aubergine were mauled by possums before they were ripe.
One of my fave ways to prepare eggplant is this super simple ratatouille. Gotta love a dish you just chop some veg, set your timer and let the oven do the rest!

Easy 1-Dish Ratatouille
Ingredients
- 2 red capsicum (bell pepper)
- 2-3 zucchini (courgette)
- 1 large eggplant (aubergine) or 2 medium
- 1 tablespoon sherry or wine vinegar
- 1 bunch basil or parsley, to serve
- aioli or mayo, to serve
Instructions
- Preheat your oven to 200C (400F). Chop veg into 2cm (1in) chunks. Place veg in a large roasting pan. Drizzle generously with olive oil and toss to mix. Sprinkle with salt.
- Roast veg for 45-50 minutes. Stirring once or twice.
- When all the veg are soft, remove from the oven toss in the vinegar. Taste and season with more salt and /or vinegar if needed.
- Toss through herbs and serve hot or at room temp with a big dollop of aioli or mayo.
Variations
short on time – pan fry veggies in oil until soft instead of roasting. Or increase oven temp to 250C (480F). Check and stir after 20 minutes. Should take about 30 total.
different veg – finely chopped onion, garlic, cherry tomatoes or diced tomato, fennel or summer squash. Or even some mushrooms for a bit of Autumn flavour.
caponata – replace the zucchini and capsicum with an extra eggplant and finely chopped onion. Toss in toasted pine nuts to serve.
more substantial (carb-lovers) – toss in cooked pasta, quinoa or brown rice and serve with grated Parmesan. Or you could serve with crusty baguette.
more substantial (low carb) – extra aioli. Serve with roast macadamias or walnuts and a fried egg.
carnivore – add cooked chicken, bacon, sausages or chorizo.
more substantial – add some protein! Cooked chicken or sausages or chorizo are great. Or try a poached egg, grilled Halloumi, salty feta, a handful of nuts or cooked beans or legumes for vegetarians.
favourite lunch – toss in a drained can of sardines or tuna and serve on a bed of salad leaves.
keto / ultra low carb – replace peppers with baby spinach tossed in at the end.
Waste Avoidance Strategy
red capsicum (bell peppers) – keep in the fridge for a few weeks. For longer grill and store in an airtight jar under oil. Or freeze them.
zucchini – will keep for 2 weeks or longer in a plastic bag in the fridge. To keep it even longer, cook sliced zucchini in a little butter until just soft then store in an airtight container in the fridge.
eggplant – will keep for a few weeks in a plastic bag in the fridge. For longer, sliced and rub with oil and grill until soft and browned. Can be frozen if needed.
sherry or red wine vinegar – keep it in the pantry.
basil – make basil oil by packing washed and dried leaves in a clean jar and covering with extra virgin olive oil. Or you can freeze the leaves, they’ll wilt but will still be delicious.
parsley – will keep in the fridge wrapped in a plastic bag for a few weeks. Can be frozen or make a parsley oil by packing the leaves into a clean jar and covering with extra virgin olive oil.
Problem Solving Guide
bland – more salt. and possibly more vinegar. if it still needs more add a drizzle of hot sauce, chilli oil or a sprinkling of a favourite spice.
too dry – More mayo or a good drizzle of extra virgin olive oil.
no oven – pan fry each of the veg separately in a frying pan or wok.
Prepare Ahead
Yes! Just cook as per the recipe but keep the herbs and aioli / mayo separately. Will keep in the fridge for 2 weeks or can be frozen.

I love this recipe and always make extra! The leftovers make great pizza topping just with some mozzarella or boconcini.
Excellent idea Kate!
Thanks for sharing.
Have you tried the Lebanese Ratatouille? I’m making it this week with curry powder for an Indian vibe.
I was just wondering what to make tonight! thanks for the suggestion. I also dont like adding tomatoes as it goes watery. I have in the past added a bit of tomato paste and just rubbed it in with the oil, sundried tomato sounds good too. Up here in the tropics I grow those round thai eggplant, so easy.
I agree with tomatoes and ratatouille Gillian. Lucky to having Thai eggplant. Enjoy!
Great meal. the vinegar cuts through the oil and gives good flavor. Can’t understand the addition of aioli or Mayo as this adds oil to the meal. I tried with and without the mayo, and it didn’t seem to need it.
Glad you liked it Denise!
I add the mayo because I find I need to add some calories to make it filling enough – but if you’re happy without thats great 🙂
Made this tonight. As it was cooking, I was worried because I usually make a ratatouille which includes tomatoes and is more like sauce and this was quite dry. However, it was very delicious! I did add a little bit of chopped sun-dried tomatoes (packed in oil) towards the end of the cooking. Served it over some leftover couscous with a little parmesan sprinkled on top. This recipe is going on my favorites list for sure!
Oh yay Ellie! Nice addition with the sun dried tomatoes 🙂
Yay Ellie
