Mediterranean Roasted Vegetables

The full ingredients list and instructions are found in the printable recipe card at the end of this post. I highly recommend reading the blog post all the way through so that you don’t miss any tips or substitution suggestions; to ensure that you have all the ingredients and equipment required, and to understand the steps and timings involved.

Struggling for new side dishes to make for dinner? Why not give these Mediterranean roasted vegetables a try? They’re really easy to make and they’re a great way to use up any leftover vegetables sitting in your refrigerator.

If you don’t have the vegetables used here, feel free to substitute any sturdy veggie you have on hand, such as carrots, fennel, parsnips, zucchini (courgette), and eggplant (aubergine).

Roasting deepens and intensifies the inherent sweetness of vegetables; so don’t be surprised if this becomes a new family favorite!

This recipe calls for Herbs de Provence, but Italian seasoning can be used instead. This will alter the flavor profile a bit, but the result will still be delicious.

Ingredients & Equipment Used In This Recipe

While most ingredients can be bought in grocery stores, for your convenience, any specialized or notable ingredients (and equipment) needed for this recipe have been listed below and linked to Amazon or other stores if available online.

It does not include staple ingredients such as oil, salt, and pepper, as you’re likely to have those in your kitchen already. The complete list of ingredients with measurements is found in the recipe card.

  • Fresh ProduceMini Sweet Peppers, Portobello Mushrooms, Red Onion, Brussels Sprouts
  • Garlic Powder
  • Herbs de Provence – this is a herb blend and depending on the brand you buy, may contain thyme, savory, oregano, rosemary, marjoram, parsley, tarragon, and lavender. These herbs are most commonly used in French cuisine, though the flavors also pair well with Mediterranean cuisine. If you don’t want to use this blend or can’t source it, you can use the same measurement of a single herb if you prefer – rosemary, oregano, and thyme all go well with chicken, or use a mixture of herbs of your preference.
  • Or Italian Seasoningthis recipe uses store-bought Italian Seasoning, but it is so easy to make your own herb mixes, especially if you already have a bunch of herbs and spices in your pantry already. Just mix equal measures of dried basil, oregano, rosemary, parsley, and thyme. You can also add a pinch of garlic granules or powder as well as red chili flakes if you like. Store in an airtight jar and use in recipes as required.
  • Balsamic Vinegar

Recipes on The Purple Pumpkin Blog use both cup measurements and/or weighted measurements. American cups and kitchen food scales are handy pieces of equipment to have in your kitchen as it means you’ll be able to make all of the different recipes on my blog. I try to give American, imperial, and metric measurements in my recipes. You can mix cup measurements with weighted measurements, but never mix imperial (pounds, ounces, pints, etc.,) with metric (kilograms, grams, litres, etc.,).
