Roasted romesco vegetables are the kind of dish that hits every note: savory, smoky, nutty, and deeply satisfying. At Donald Recipes, I love bringing international classics to your table—and this Spanish-inspired side dish is one of my absolute favorites. It’s bold, beautiful, and brimming with Mediterranean flavor.

The heart of this dish is the romesco sauce, which dates back to the 15th century in Tarragona, Catalonia. Originally crafted by fishermen to accompany freshly grilled seafood, romesco has since evolved into a versatile vegan condiment, pairing beautifully with roasted vegetables, meats, and even pasta. Its base of roasted red peppers, nuts, and garlic, blended with olive oil and vinegar, creates a smoky, creamy sauce with a slightly tangy finish.

🧄 What You’ll Need

🔪 Essential Kitchen Tools for Roasted Romesco Veggies

Before I dive into prepping the ingredients, it’s important to have the right tools on hand. Having a few kitchen essentials ready not only makes the process smoother but also ensures your roasted vegetables come out perfectly caramelized and your romesco sauce turns out irresistibly creamy.

Here’s what I use every time:

• Baking sheet – A large sheet pan gives the veggies space to roast instead of steam.
• Parchment paper or foil – Makes cleanup quick and easy.
• Blender or food processor – Crucial for a smooth, emulsified romesco sauce.
• Mixing bowls – For tossing vegetables in olive oil, salt, and pepper.
• Chef’s knife & cutting board – For prepping your vegetable medley.

The blender or food processor is a non-negotiable in this recipe. Romesco sauce gets its signature texture from being blended until silky smooth. A high-powered blender works best, especially when handling nuts and roasted peppers.

And speaking of useful kitchen tips, if you’re into easy meal prep dishes, you’ll love these Mini Pancake Cereal Bites. They’re just as fun to make as they are to eat, and another great excuse to use your nonstick tools and mixing bowls.

🧺 Fresh Ingredients to Create Mediterranean Magic

The ingredients in this recipe are simple, but when combined, they create deep flavor complexity. Fresh vegetables, heart-healthy olive oil, and a smoky homemade romesco sauce come together for a Mediterranean masterpiece.

Here’s what you’ll need for the roasted vegetables:

• 2 cups cauliflower florets
• 1 large red bell pepper, sliced
• 1 large carrot, peeled and chopped
• 1 red onion, cut into wedges
• 1 zucchini, sliced
• 2 tablespoons olive oil
• Salt and black pepper, to taste

And for the romesco sauce:

• 1 roasted red bell pepper (jarred or freshly roasted)
• 1/4 cup almonds or hazelnuts
• 2 tablespoons tomato paste
• 1 garlic clove
• 1 tablespoon red wine vinegar
• 1/4 teaspoon smoked paprika
• 1/4 cup olive oil
• Pinch of cayenne pepper (optional)
• Salt, to taste

These ingredients are easy to find at most grocery stores and pack a ton of Mediterranean nutrition. The combination of smoky paprika and rich olive oil gives the sauce a bold yet balanced flavor. I like to roast my own red pepper for added depth, but jarred versions work beautifully when you’re short on time.

With everything in place, you’re ready to get cooking. But before we move on, if you’re experimenting with veggie-forward dishes, you should also try my decadent Red Velvet Beet Bars with Sour Cream Frosting. They’re an unexpected twist on a classic dessert using wholesome ingredients.

🔥 Step-by-Step: How to Roast Romesco Vegetables

🥗 Step 1 & 2: Prep and Roast the Veggies

Getting the best flavor starts with how you treat your vegetables. Roasting is where the magic happens — the high heat intensifies natural sweetness, creates crisp edges, and adds irresistible caramelized notes.

Start by preheating your oven to 425°F. This temperature is ideal for roasting — not too low to make them soggy, not too high to risk burning before they’re tender.

Next, line a baking sheet with parchment paper or foil. This helps prevent sticking and speeds up cleanup.

Now it’s time to toss:

• Add all your prepped veggies — cauliflower, bell pepper, zucchini, carrot, and onion — to a mixing bowl.
• Drizzle in 2 tablespoons of olive oil, and season generously with salt and pepper.
• Toss everything together until evenly coated.

Spread the vegetables in a single layer on the baking sheet. Avoid crowding; overlapping will steam rather than roast them. Halfway through the 25–30 minute roast, flip the vegetables to ensure even browning and caramelization on all sides.

Pro tip: If you love crispy edges (and who doesn’t?), make sure the cut side of each veggie touches the sheet pan directly.

🫕 Step 3 & 4: Blend the Sauce & Bring It All Together

While the veggies roast, let’s make the romesco sauce. This is where flavor gets serious.

In your blender or food processor, combine:

• 1 roasted red bell pepper
• 1/4 cup almonds or hazelnuts
• 1 garlic clove
• 2 tablespoons tomato paste
• 1 tablespoon red wine vinegar
• 1/4 teaspoon smoked paprika
• Pinch of cayenne pepper (optional)
• A good pinch of salt

Blend while slowly streaming in 1/4 cup olive oil. This helps emulsify the sauce, turning it smooth and luscious. Adjust the consistency by adding a splash of water if needed.

Once your vegetables are beautifully golden and crispy, remove them from the oven and let them rest a couple minutes.

To serve, either:

• Drizzle the romesco sauce generously over the warm vegetables, or
• Serve it on the side as a flavorful dipping sauce

Garnish with chopped parsley or crushed nuts for added freshness and crunch. Presentation-wise, you’re already winning—but the flavors will keep guests coming back for more.

🍽 Serving Suggestions & Storage Tips

🍴 How to Serve Romesco Vegetables Like a Pro

These roasted romesco vegetables are incredibly flexible and can play different roles in your meals — from the star of your dinner plate to a vibrant, flavor-packed side.

Here are my favorite ways to serve them:

• Over fluffy grains like couscous, quinoa, or brown rice for a complete plant-based meal
• Tucked inside warm pita bread or wraps with a smear of hummus or tzatziki
• As a side to grilled proteins like chicken thighs, lamb skewers, or marinated tofu
• Topped with crumbled feta or goat cheese if you’re open to a creamy finish

Don’t be afraid to go creative — the beauty of this dish lies in its adaptability. For instance, it works beautifully in Mediterranean-style bowls with olives, chickpeas, and a drizzle of lemon vinaigrette.

If you’re putting together a weekend brunch or a fun mezze-style spread, try serving it alongside something playful and unexpected, like these Mini Pancake Cereal Bites. They may be sweet, but they balance beautifully with the smoky-savory notes of the romesco sauce

🧊 Smart Storage Tips & Meal Prep Ideas

Roasted vegetables and romesco sauce are excellent candidates for meal prep. You can make everything ahead of time and enjoy flavorful lunches or dinners all week long.

Here’s how I recommend storing them:

• Vegetables: Store in an airtight container in the fridge for up to 4 days. Pop it back into a 350°F oven for about 10 minutes to bring back its crispiness.
• Romesco Sauce: Keeps well in the fridge for up to 1 week. It also freezes beautifully—just portion it out into small containers and freeze for up to 3 months.

When reheating, I suggest avoiding the microwave if possible. While it’s quick, it softens the roasted edges. An oven or air fryer brings back that signature crispness and warmth.

And if you end up with leftover sauce, try it as a spread on sandwiches, a dip for chips, or even a topping for grilled vegetables on a different night.

🌀 Variations & Customizations

🌶 Turn Up the Heat (or Tone It Down)

One of the most exciting things about this dish is how easily it can be adjusted to suit your taste. Whether you’re a fan of extra spice or you prefer a milder, nuttier flavor, romesco vegetables offer room to experiment.

If you want a spicy kick, try one of these tweaks:

• Add roasted jalapeño or chipotle pepper to the romesco sauce
• Dust the vegetables with crushed red pepper flakes just before they go into the oven.
• Mix in a bit of hot smoked paprika instead of sweet for deeper, bolder flavor

Not into spice? No worries. You can skip the cayenne and opt for a milder, paprika-forward romesco. The sauce still delivers tons of flavor without heat.

These customizations are a great way to create versions of the dish the whole family can enjoy. And if you’re looking for another unexpected recipe twist that hits that sweet-spicy zone, check out my Sticky Toffee Banana Pudding — it’s warm, bold, and completely comforting.

🧀 Nut-Free, Dairy-Friendly & More

If you’re cooking for dietary restrictions, romesco vegetables can still fit the bill beautifully.

Here are some easy swaps and additions:

• Nut-Free Version: Replace almonds or hazelnuts with sunflower seeds or pumpkin seeds. You can also omit nuts altogether and add a bit of toasted bread for body (traditional in older Catalan recipes).
• Add Cheese: For a creamy contrast, top the finished vegetables with crumbled feta, goat cheese, or even parmesan shavings.
• Make It a Meal: Serve over a bed of farro, wild rice, or herbed couscous with chickpeas or grilled halloumi for a complete Mediterranean bowl.

Don’t be afraid to make this dish your own. The foundation of roasted vegetables and smoky romesco is endlessly versatile — and works across different seasons, too. Swap in sweet potatoes or Brussels sprouts in the fall, or fresh asparagus and cherry tomatoes in spring.

And if you enjoy turning veggies into decadent desserts (yes, really!), you’ll fall for my Red Velvet Beet Bars with Sour Cream Frosting. It’s another way I sneak in produce and keep things interesting.

“Romesco vegetables” simply refers to roasted or grilled vegetables served with — or flavored by — romesco sauce. The term is most commonly used in Mediterranean and Spanish-inspired cuisine where romesco acts as both a sauce and a marinade.

• Roasted veggie platters
• Grilled kebabs

• Wraps and sandwiches

The beauty is in the simplicity: roasted vegetables, bold sauce, minimal ingredients — and massive flavor payoff.

Here are a few key tips:

1. Use high heat (425°F) to ensure caramelization
2. Don’t overcrowd the pan — give veggies space to crisp up
3. Cut veggies to similar sizes so they cook evenly
4. Toss well in oil, salt, and pepper for perfect seasoning
5. Flip halfway through for golden edges on both sides
