If you love fresh summer pasta salads packed with vegetables, this Grilled Ratatouille Pasta Salad with Balsamic Vinaigrette is a recipe worth making.
Ratatouille is a classic French Provençal dish — zucchini, eggplant, bell peppers, and tomatoes cooked together with garlic and herbs.
It is simple, deeply flavourful, and completely vegetarian.
Inspired by classic Mediterranean flavors, this grilled vegetable pasta salad is perfect for summer BBQs or easy meal prep lunches.
It works well, at room temperature, or straight from the fridge the next day. It travels well to potlucks and picnics. It makes a stunning side dish for grilled meat or fish.
Why Grilling the Vegetables Makes All the Difference
You could roast these vegetables in the oven and still get a great pasta salad. But grilling does something to them that roasting simply cannot replicate.
The high direct heat of the grill caramelises the natural sugars in the vegetables and creates those beautiful smoky, slightly charred edges.
All of that grilled flavour then gets absorbed by the pasta when everything is tossed together.
Ingredients
For the pasta salad:
- 12 oz pasta (rotini, penne, or fusilli)
- 1 medium zucchini, sliced lengthwise
- 1 small eggplant, sliced
- 1 red bell pepper, cut into large pieces
- 1 yellow bell pepper, cut into large pieces
- 1 cup cherry tomatoes
- 2 garlic cloves, minced
- 2 tbsp olive oil
- Salt and black pepper to taste
- ¼ cup fresh basil, chopped
For the balsamic vinaigrette:
- 3 tbsp balsamic vinegar
- 5 tbsp olive oil
- 1 tsp Dijon mustard
- 1 tsp honey
- 1 garlic clove, minced
- Salt and black pepper to taste
How To Make Grilled Ratatouille Pasta Salad
Step 1 — Cook the pasta
Bring a large pot of well-salted water to a boil. Cook the pasta according to package directions until al dente — you want it cooked through but with a little bite left since it will continue to absorb the dressing as it sits.
Drain the pasta and rinse with cold water to stop the cooking and cool it down. Drizzle with a little olive oil and toss to prevent sticking. Set aside.
Step 2 — Prep the vegetables
Slice the zucchini lengthwise into long planks about ½ inch thick — this size grills beautifully without falling through the grates and gives you good grill marks.
Slice the eggplant into rounds about ½ inch thick. Eggplant absorbs oil like a sponge so do not overdo it with the olive oil — a light brush on both sides is plenty.
Cut the red and yellow bell peppers into large flat pieces — remove the seeds and core and cut them into sections big enough to lay flat on the grill without falling through.
Place all the vegetables and the cherry tomatoes in a large bowl. Drizzle with the olive oil, add the minced garlic, season generously with salt and pepper, and toss to coat everything evenly.
Step 3 — Grill the vegetables
Heat your grill or grill pan to medium-high. You want it properly hot before the vegetables go on — the heat is what creates those gorgeous caramelised edges.
Grill the zucchini and eggplant slices for 3–4 minutes per side until tender and well-marked. Grill the bell pepper pieces for 4–5 minutes per side until slightly blistered and softened.
For the cherry tomatoes, place them directly on the grill or in a grill basket and cook for 2–3 minutes until they are blistered and starting to burst. They do not need to be flipped — just let the heat work on them until they collapse slightly.
Remove all the vegetables from the grill and let them rest for a few minutes until cool enough to handle.
Step 4 — Chop the grilled vegetables
Once the vegetables have cooled slightly, chop them into bite-sized pieces. You want roughly 1-inch pieces so every forkful of pasta salad gets a good mix of everything.
Leave the cherry tomatoes as they are if they are still intact, or halve them if they are large.
Step 5 — Make the balsamic vinaigrette
In a small bowl or jar, combine the balsamic vinegar, olive oil, Dijon mustard, honey, and minced garlic. Season with salt and pepper.
Whisk everything together vigorously until the dressing is emulsified and smooth — or put it all in a jar with a tight lid and shake it hard for 30 seconds. Taste and adjust — more balsamic for tanginess, more honey for sweetness, more salt if it needs it.
Step 6 — Assemble the salad
Add the cooked pasta to a large bowl. Add the chopped grilled vegetables and toss to combine.
Pour the balsamic vinaigrette over the salad and toss everything together until fully coated. Start with about ¾ of the dressing and taste — add more if you want it more dressed.
Add the fresh chopped basil and toss once more.
Taste and adjust seasoning with salt and pepper. The salad should be bright, tangy, smoky, and herby all at once.
Step 7 — Rest before serving
Let the salad sit for at least 15–20 minutes before serving. This resting time allows the pasta to absorb the dressing and the flavours to develop and meld together. The salad tastes significantly better after this rest than it does immediately after tossing.
Serve warm, at room temperature, or chilled depending on your preference. Add a little extra fresh basil and a drizzle of good olive oil right before serving if you want it to look extra beautiful.
Tips for the Best Grilled Ratatouille Pasta Salad
Salt the pasta water generously. It should taste like the sea. This is the only opportunity to season the pasta itself and under-seasoned pasta will make the whole salad taste flat no matter how good the dressing is.
Do not overcrowd the grill. Give each piece of vegetable space — crowding causes steaming rather than grilling and you will miss out on those caramelised edges that make this salad so special.
Cut the vegetables into uniform sizes for grilling. Similarly sized pieces cook at the same rate. Wildly different sizes mean some are overdone while others are still raw.
Make the dressing ahead. The balsamic vinaigrette can be made up to a week ahead and stored in the fridge. Let it come to room temperature and shake well before using since the olive oil will solidify slightly when cold.
Reserve some dressing for serving. The pasta absorbs quite a lot of the dressing as it sits — especially if making ahead. Keep a little extra to toss through right before serving to freshen it up.
Do not skip the resting time. The difference between a pasta salad that has rested for 20 minutes and one that has not is significant. The flavours meld, the dressing absorbs, and everything tastes more cohesive and developed.
Add the basil last. Fresh basil bruises and darkens very quickly once chopped. Add it right at the end and again as a garnish when serving for the brightest colour and freshest flavour.
Variations
Add feta cheese — Crumble generous amounts of salty feta over the finished salad. The creamy, briny feta against the smoky vegetables and tangy dressing is an incredible combination.
Add olives — A handful of Kalamata olives tossed through the salad adds a lovely briny depth that fits perfectly with all the Mediterranean flavours here.
Add artichoke hearts — Drained and roughly chopped marinated artichoke hearts are a wonderful addition that takes the whole salad in a more elevated direction.
Add protein — Top with grilled chicken, sliced grilled steak, or seared halloumi for a more substantial meal.
Make it vegan — This salad is already plant-based — just swap the honey in the dressing for maple syrup.
Add sun-dried tomatoes — A small handful of roughly chopped sun-dried tomatoes stirred through the salad adds concentrated bursts of intense tomato flavour throughout.
Serving Ideas
This salad works beautifully in so many different situations.
Serve it as a side dish alongside grilled chicken, fish, or lamb. Bring it to a potluck or barbecue — it travels well, holds up in warm weather, and tastes great at room temperature. Pack it for lunches throughout the week — it keeps getting better in the fridge. Serve it as a light vegetarian main with a good piece of crusty bread and a glass of white wine.
For a more composed presentation, pile the pasta salad on a large platter, scatter extra fresh basil over the top, crumble feta over everything, and finish with a final drizzle of olive oil and balsamic glaze.
Make-Ahead and Storage
This pasta salad is genuinely better the next day. The dressing soaks in overnight and all the flavours develop beautifully.
Make the full salad up to 24 hours ahead and store covered in the fridge. Before serving let it come to room temperature for 15–20 minutes and toss with an extra drizzle of olive oil and a splash more balsamic vinegar to refresh it. Add fresh basil right before serving.
Store in an airtight container in the fridge for up to 4 days. The vegetables will soften slightly as it sits but the flavour keeps improving.
Frequently Asked Questions
Can I roast the vegetables instead of grilling? Absolutely. Spread everything on a large baking sheet in a single layer, drizzle with olive oil, season with salt and pepper, and roast at 425°F for 20–25 minutes until golden and caramelised. You will not get the smoke but you will get the same wonderful caramelised flavour.
Can I use a different pasta shape? Rotini, penne, and fusilli all work perfectly because their shapes trap the dressing and little bits of vegetable in every bite. Bow ties also work well. Avoid long pasta shapes like spaghetti or linguine — they do not work as well in a cold salad.
Can I serve this warm? Yes — it is wonderful served warm right after everything is tossed together. Slightly warm pasta salad with the fresh basil wilting gently into it is genuinely delicious.
Can I add cheese? Feta and fresh mozzarella both work beautifully. Shaved parmesan is also excellent stirred through right before serving.
My salad tastes bland — what do I do? Almost always this is a seasoning issue. Add more salt, a little more balsamic vinegar, and taste again. Under-seasoned pasta salad is always the culprit. Be generous with the salt at every stage.
