📝 Notes and Substitutions
- Baby Red Potatoes: Their creamy texture and thin skins make them perfect for roasting. Cut them into even pieces for consistent crisping.
- Substitute: Yukon Gold or fingerling potatoes work just as well. For a lower-carb option, try chunks of cauliflower or parsnips.
- Zucchini: Adds moisture and a tender bite. Roast it with the other veggies but avoid overcooking to keep it from getting too soft.
- Substitute: Yellow squash or eggplant slices for a similar texture.
- Bell Peppers: Red and yellow peppers bring sweetness and color.
- Variation: Add green bell pepper for a slightly bitter balance or roasted poblano for a smoky twist.
- Red Onion: Caramelizes beautifully and adds a mild, sweet flavor when roasted.
- Substitute: Shallots or sweet onions for a gentler flavor, or white onions for a sharper bite.
- Carrots: Their natural sweetness deepens as they roast, balancing the savory herbs.
- Variation: Try rainbow carrots for extra color or sweet potatoes for a heartier version.
- Cherry Tomatoes: They burst with juicy flavor and add brightness to the dish.
- Variation: Use grape tomatoes or sun-dried tomatoes for a more concentrated flavor.
- Olive Oil: Use a good-quality extra virgin olive oil for the best flavor and crisp texture.
- Pro Tip: Don’t skimp—olive oil helps the herbs adhere and promotes even roasting.
- Herbs & Spices (Thyme, Rosemary, and Sumac): These classic Mediterranean seasonings add earthy, citrusy, and aromatic depth.
- Substitute: Use Italian seasoning or Herbes de Provence if you don’t have thyme and rosemary. For a different finish, try smoked paprika or za’atar in place of sumac.
- Garnishes (Parsley, Feta, Lemon, Sea Salt): Fresh parsley and lemon brighten the roasted flavors, while feta adds a creamy, tangy contrast.
- Variation: Swap feta with goat cheese or shaved Parmesan; add a drizzle of balsamic glaze for an extra-rich finish.
Expert Tip
For perfectly crispy potatoes, par-boil them before roasting! Boil the cut potatoes in water for about 5–7 minutes, just until the edges start to soften. Drain well and let them steam-dry for a few minutes—this removes excess moisture and roughens the surface, helping them crisp beautifully in the oven. Steam-drying means letting the hot, drained potatoes sit for a few minutes after boiling—without covering them—so the remaining surface moisture evaporates naturally.
👩🏼🍳 How to Make Mediterranean Roasted Vegetables

- Step 1: Combine the thyme, rosemary, sumac, salt, and pepper with the olive oil. Set aside. Preheat oven to 425°F.

- Step 2: Toss the par-boiled potatoes with about half of the herbed oil and place them on a large parchment paper-lined baking sheet. Roast for 15 minutes.

- Step 3: Toss the carrots with 2 teaspoons of the herb oil and add them to the pan. Spread ingredients out evenly and bake another 10 minutes.

- Step 4: Toss the zucchini, bell peppers, and onion with the remaining herb oil. Spread out on the pan and bake for another 10 minutes.

- Step 5: Add the tomatoes and olives and bake for a final 10 minutes.

- Step 6: Transfer to a large platter and garnish with freshly squeezed lemon, chopped Italian parsley, and crumbled feta.
