4-Ingredient Balsamic Roasted Peppers

Last updated on September 7th, 2025

My favourite thing about this 4-Ingredient Balsamic Roasted Peppers recipe is that there is minimal (and I mean almost ZERO) prep involved. Well, that and the fact that they taste like summer on a plate. All you have to do is season, toss and roast (or even grill) and you’ll have a simply delicious snack or side that presents beautifully!

I’ve said it before, roasting is my favourite way to prepare almost any vegetable. I just love those smoky, blistered edges and jammy, tender centres! A mostly hands-off affair, it’s pretty hard to beat even on these hot and humid July days. In just 30 minutes, you can have a delicious appetizer, snack or side dish that’s perfect for grazing or to serve alongside any grilled main.

Ingredients you’ll need to make these 4-ingredient balsamic roasted peppers

• 1½ lbs (700 g) mini sweet peppers
• Extra-virgin olive oil
• Balsamic vinegar
• Kosher or fine sea salt

That’s all it takes to make the magic happen!  

Here’s how they come together

First, place whole peppers, including the stems, in a 9×13-inch glass baking dish.

Next, drizzle them with olive oil and balsamic vinegar, season with salt and toss.

Roast for 25 minutes until they’re bubbling, blistered and tender.

Remove from oven and serve or let cool and store, sealed, in the refrigerator.

Tips for roasting mini peppers

While I LOVE the charred edges that come with roasting sweet peppers on a sheet pan, for this recipe you’ll want to use a deep baking dish. This will prevent them from drying out too quickly, and create space for the oil, vinegar and the peppers’ natural juices to form a glaze-like sauce that will keep the peppers nice and moist. Perfect for dipping with your favourite crusty bread!

Serve these 4-ingredient Balsamic Roasted Peppers as a side with grilled fish or a vegetarian main, as part of a snack board with your favourite cheeses or in sandwiches and burgers!
