Roasted Vegetables Recipe with Feta and Lemon Traybake

This roasted vegetables recipe combines golden potatoes, carrots, peppers, zucchini, and tomatoes with salty feta and bright lemon. It makes a colorful, Mediterranean-inspired side dish, and roasting the vegetables in stages helps each one turn tender without losing its texture.

Ingredients

1 lb baby potatoes (450 g), halved or quartered so pieces are about 1 inch (2.5 cm)
2 medium carrots (200 g), peeled if needed and cut into ½-inch (1 cm) rounds
1 medium red onion (180 g), cut into thick wedges
1 red bell pepper (180 g), seeded and cut into 1-inch (2.5 cm) pieces
1 medium zucchini (250 g), cut into ¾-inch (2 cm) half-moons
1½ cups cherry tomatoes (250 g), left whole
3 tbsp extra-virgin olive oil (45 ml), divided
3 garlic cloves (9 g), finely grated or minced
1 tsp dried oregano (1 g)
¾ tsp fine salt (4 g), plus more to taste
½ tsp freshly ground black pepper (1 g)
1 medium lemon (about 100 g), finely zested and juiced; use about 1 tsp zest and 2 tbsp juice (30 ml)
5 oz feta cheese (140 g), crumbled
2 tbsp chopped fresh parsley (8 g), for serving

Instructions

Heat the oven and prepare the pans. Set a rack in the center of the oven and heat it to 425°F (220°C). Line two large rimmed baking sheets with parchment if you want easier cleanup. Using two pans gives the vegetables room to roast; if they are piled together, they release steam and soften rather than developing browned edges.
Season the firm vegetables. Put the potatoes and carrots in a large bowl. Add 2 tbsp (30 ml) of the olive oil, the garlic, oregano, salt, and black pepper, then toss until the pieces are coated. Divide them between the pans and spread them in a single layer, keeping cut sides of the potatoes against the pan where possible. Roast for 15 minutes.
Add the vegetables that cook faster. While the potatoes and carrots roast, toss the onion, bell pepper, and zucchini with the remaining 1 tbsp (15 ml) olive oil. When the first 15 minutes are up, remove the pans and turn the potatoes and carrots with a spatula. Add the onion, pepper, and zucchini, distributing everything evenly. Return the pans to the oven for 10 minutes.
Add the tomatoes and finish roasting. Take out the pans and scatter the whole cherry tomatoes over the vegetables. Roast for a final 10 minutes, or until the potatoes are tender when pierced with a small knife, the carrots are easily pierced, and several vegetables have browned edges. If one pan browns more quickly than the other, switch their positions for this final stretch. The full oven time is about 35 minutes.
Finish with lemon and feta. Transfer the vegetables to a warm serving platter, or finish them on the pans. Add the lemon zest and 1 tbsp (15 ml) lemon juice, then taste and add more juice or salt if needed. Scatter the feta and parsley over the top. Serve while warm, so the feta softens slightly but keeps some of its crumbly texture.

Tips

Cut for even cooking. The potatoes and carrots need a head start because they take longer than zucchini, peppers, and tomatoes. Aim for similarly sized potato pieces and carrot rounds, and avoid cutting the zucchini too thin. Thin pieces can collapse before the root vegetables are ready.
Give the vegetables breathing room. Two pans are useful even if the ingredients might technically fit on one. Leave a little space between pieces, and use separate pans rather than stacking vegetables. For an especially well-browned finish, rotate the pans between oven racks halfway through cooking.
Adjust the salt for your feta. Feta varies in saltiness, so the measured salt seasons the vegetables but should not be treated as the final word. Taste after adding the cheese and lemon, then season again only if the dish needs it. If using feta packed in brine, drain it well before crumbling.
Use fresh lemon at the end. Lemon juice added before roasting can lose its fresh, lively flavor, while the zest brings fragrance without extra acidity. Add the juice after the vegetables come out of the oven, starting with the listed amount and adding a little more to taste.

Serving Suggestions

Serve the tray of vegetables warm as a substantial side for roast chicken, grilled fish, lamb, or simple pan-seared tofu. It also works as the centerpiece of a vegetarian meal: spoon it over couscous, orzo, farro, or rice so the grains catch the lemony juices from the pan. Add warm flatbread or crusty bread to scoop up the softened tomatoes and feta.

For a more filling lunch, tuck the vegetables into pita with a spoonful of hummus or thick yogurt. A crisp green salad with a plain vinaigrette is a good partner because it balances the sweet, browned vegetables without competing with the lemon. If serving a group, put extra lemon wedges and a small bowl of feta on the table so people can adjust their portions.

Variations

Swap in seasonal vegetables. Cauliflower florets, broccoli, or cubed eggplant can replace some of the zucchini or pepper. Cut cauliflower and broccoli into bite-size pieces and add them with the onion and pepper. Eggplant absorbs oil readily, so cut it into even cubes and toss carefully rather than adding extra oil by default. Very watery vegetables, such as mushrooms, are best roasted with plenty of space.

Change the herbs or cheese. Fresh thyme or rosemary can stand in for dried oregano; use about 1 tbsp (3 g) chopped fresh leaves in place of the teaspoon of dried oregano. For a milder, creamier finish, use ricotta salata instead of feta. If feta is hard to find, a firm, salty white cheese such as cotija is a practical substitute, though its flavor is less tangy and its texture may be drier.

Add beans or a little heat. For a more filling tray, fold in 1 can of chickpeas, drained and rinsed (about 1½ cups or 250 g), when you add the tomatoes. They will warm and take on the seasonings, though they will not become as crisp as oven-roasted chickpeas. For gentle heat, add ¼ tsp (0.5 g) red pepper flakes with the oregano; increase it only if you want a noticeably spicy result.

Storage and Reheating

Refrigerate leftovers within 2 hours of cooking, in a shallow airtight container. They keep for 3 to 4 days in the refrigerator. The vegetables will soften as they sit, and the feta may become a little moist, but the lemon and herbs still make leftovers useful for lunch bowls, wraps, or omelets. For the best texture, store extra feta separately and add it after reheating if you have not already dressed the whole batch.

To reheat, spread a portion on a baking sheet and warm it in a 375°F (190°C) oven for about 10 to 15 minutes, until hot throughout; larger portions may take longer. A skillet over medium heat also works, with occasional turning. The USDA FSIS recommends reheating leftovers to 165°F (74°C); check the center of the portion with a food thermometer. Microwave reheating is convenient but tends to soften the vegetables further. Freezing is possible for up to 2 months for convenience, but thawed zucchini and tomatoes will be much softer, so use them in a grain bowl or soup rather than expecting the original roasted texture.

Frequently Asked Questions

Can I roast all the vegetables at the same time? You can, but the potatoes and carrots may still be firm by the time the zucchini and tomatoes are done. The staged method gives the firmer vegetables a 15-minute head start, then adds quicker-cooking vegetables in two rounds. If you use vegetables with similar cooking times, you can adjust the sequence, but check doneness rather than relying on the clock alone.

Can I make this recipe on one baking sheet? Use one very large rimmed sheet only if the vegetables fit in a single layer with some space around them. Most standard pans are too crowded for the full quantity, and crowded vegetables steam. If you have just one standard pan, roast half the recipe at a time, or use two oven-safe pans and switch their rack positions partway through.

How do I know when the vegetables are done? Test a potato and a carrot with the tip of a small knife. Both should be tender without resistance, and the smaller vegetables should have browned edges. Tomatoes will look softened and may split, which is expected. If the potatoes need more time, leave the other vegetables on the pan and continue roasting in 3- to 5-minute increments.

Can I prepare the vegetables ahead? You can wash and cut the vegetables a day ahead, then keep them covered in the refrigerator. Store cut potatoes submerged in cold water to slow browning, and drain and dry them very thoroughly before seasoning so excess water does not hinder browning. For the freshest flavor, wait to add lemon juice, feta, and parsley until after roasting.

Can I use frozen vegetables? Fresh vegetables give the most reliable browned edges, but sturdy frozen vegetables such as cauliflower can work if thawed and dried well first. Frozen zucchini and tomatoes tend to release considerable water and become soft, so they are less suitable here. If using frozen ingredients, spread them widely across the pans and expect to roast until visible moisture has evaporated and the vegetables are tender.
