Ingredients

Tomatoes – cocktail tomatoes are easy to halve and roast well. Cherry tomatoes or mini Roma tomatoes are also suitable.
Zucchini – choose firm, shiny medium zucchini. Very large zucchini can be watery, so medium ones are best for roasting.
Red bell pepper – look for peppers that feel firm and have smooth, glossy skin. Avoid soft peppers, as they are past their best.
Mushrooms – white, brown, portobello, or baby bella mushrooms all work. They should be firm, smooth, and plump.
Potatoes – any variety can be used. Cut them smaller than the softer vegetables so they cook at the same rate.
Carrot – a regular medium carrot adds color and sweetness.
Onion – red onion adds a lovely flavor, but white or brown onion can also be used.
Garlic cloves – fresh garlic is best for this recipe. Leave the cloves whole so they roast gently.
Olive oil – regular olive oil is fine, though extra virgin olive oil can be used if preferred.
Rosemary – fresh rosemary gives a wonderful Italian aroma.
Oregano – dried oregano is convenient and has a concentrated flavor that works beautifully with roasted vegetables.
Salt and pepper – seasoning is important because it brings out the natural flavor of the vegetables and helps them taste balanced.

Divide the vegetables between the baking sheets in a single layer and roast until tender with lightly browned edges.

Hint: Do not crowd the baking sheets. If the vegetables are piled on top of each other, they will steam instead of roast and may turn soft or watery.

Substitutions

Vegetables – use other Mediterranean vegetables if you like. Eggplant, fennel, yellow squash, or marinated artichokes can be delicious options.
Olive oil – sunflower oil or avocado oil can be used instead of olive oil.
Herbs – rosemary and oregano are classic, but thyme, sage, bay leaves, or Italian seasoning can also be used.

Variations

Lemon and parsley – mix finely grated lemon zest with chopped fresh parsley and sprinkle over the roasted vegetables before serving.
Nutty – add toasted pine nuts or slivered almonds for crunch and a nutty flavor.
Cheesy – sprinkle with grated Parmesan for an Italian finish, or use crumbled feta for a Mediterranean-style variation.

Equipment

You will need a large mixing bowl to coat the vegetables evenly with oil and herbs. Two large baking sheets are also important because the vegetables need space to roast in a single layer.

Storage

Store leftover Italian roasted vegetables in a sealed container in the refrigerator. Reheat them in the microwave, warm them in the oven, or enjoy them cold as a roasted vegetable salad.

Top tip

Preheat the oven properly. A hot oven helps vegetables roast instead of steam. Check them halfway through cooking and rotate the trays if your oven heats unevenly.
Cut vegetables according to cooking time. Zucchini and bell peppers cook faster, so cut them larger. Potatoes and carrots take longer, so cut them smaller.
Season generously. Salt enhances flavor and helps the vegetables caramelize without tasting flat.
Use a single layer. Crowded vegetables release moisture and become soggy. Give them enough room on the baking sheets.
Use dark baking sheets if possible. Dark baking sheets absorb heat quickly and can help the vegetables brown well.
Choose baking sheets rather than deep pans. Low sides allow moisture to evaporate and air to circulate around the vegetables.

FAQ

What is the secret to roasting vegetables?

The secret is to coat the vegetables with enough oil and spread them in one single layer. This helps them caramelize instead of steam. Avoid piling the vegetables on the baking sheet.

What vegetables are popular in Italy?

Tomatoes, zucchini, bell peppers, eggplant, fennel, and artichokes are all popular vegetables in Italian cooking. What is used often depends on the season.

How do I get oven-roasted vegetables to release less water?

Start with fresh, firm vegetables and avoid overcrowding the baking sheets. While vegetables naturally release moisture as they cook, arranging them in a single layer allows that moisture to evaporate more effectively.
