Catalan Salad Recipe: Smoky Roasted Pepper and Anchovy Crunch

This Catalan salad recipe transforms smoky roasted vegetables into a vibrant, flavorful dish that captures the heart of Spanish cuisine. The traditional Ensalada Catalana features tender eggplant, peppers, onions, and tomatoes roasted until caramelized, then layered with optional anchovies for a briny crunch.

What makes this salad special is its balance of textures—creamy roasted vegetables, crispy anchovies, and a drizzle of garlic aioli that ties everything together.

The roasting process is key to developing deep, smoky flavors without overpowering the natural sweetness of the vegetables. I’ve perfected a method that ensures even cooking while preserving the vegetables’ integrity, resulting in a dish that’s both rustic and refined.

This vegetarian-friendly salad (anchovies optional) is a staple in Catalan homes, often served as a light main or side during warm weather.

By the time you assemble this salad, you’ll have a dish that’s visually stunning with its deep reds and golden browns, and packed with layers of flavor—savory, slightly sweet, and tangy all at once.

The roasted vegetables hold their shape while absorbing the garlic aioli, creating a harmonious bite that’s both satisfying and elegant.

Perfect for summer gatherings, picnic lunches, or a simple yet impressive vegetarian meal, this Catalan salad is a testament to how simple ingredients can come together to create something extraordinary. Let’s get started on bringing this classic dish to your table.

Ingredients for catalan salad

Roasted vegetables, smoky spices, and briny anchovies—this salad packs Catalan flavors in every bite.

The vegetables are the heart of this salad, so don’t skimp on quality. Look for firm eggplant and vibrant bell peppers at the market—they’ll roast up sweeter and hold their shape better. I always grab Spanish smoked paprika from the bulk section at Whole Foods for that authentic smoky depth, but any quality smoked paprika will work. Soak the onions in cold water for 10 minutes before roasting to mellow their sharpness—trust me, it’s worth the extra minute. For the anchovies, if you’re avoiding them, swap in vegan anchovy-free aioli or extra lemon juice for brightness.

No smoked paprika? Substitute with a pinch of liquid smoke (start with 1/4 tsp) or extra garlic. The anchovies are optional, but if you’re using them, make sure they’re packed in olive oil—those in vinegar won’t work here. For the aioli, if you don’t have mayo, blend 1/2 cup neutral oil with 1 tbsp lemon juice and 1 tsp Dijon mustard for a lighter version. The tomatoes can be swapped for heirloom varieties if you want extra sweetness, but Roma holds up best during roasting. And if you’re short on time, pre-cut vegetables from the salad bar work in a pinch—just pat them dry before roasting.

Roasted vegetables keep in the fridge for 4 days if stored in an airtight container, but they’re best eaten within 2 days for peak texture. The aioli should be made fresh and stored separately—it’ll last 3 days in the fridge. For serving, assemble the salad just before eating so the anchovies (if using) stay crisp. This dish reheats beautifully—just warm the vegetables gently in a skillet with a drizzle of olive oil, then toss with fresh aioli. Leftovers make great picnic lunches, packed in individual containers with a side of crusty bread.

Step-by-step instructions for Catalan salad

Here's how to build this smoky, crunchy salad with perfect roasted vegetables and rich anchovy aioli.

Preheat your oven to 425°F and line two baking sheets with parchment paper. Toss the 1 lb eggplant cut into 1-inch cubes, 2 whole red bell peppers sliced into 1-inch strips, and 1 whole yellow onion thinly sliced in a large bowl with 0.25 cup of the extra-virgin olive oil and 0.25 tsp of the smoked paprika. Spread everything in a single layer on the baking sheets.

Roast for 25-30 minutes, stirring once halfway, until the eggplant is tender and the edges of the peppers and onions are deeply charred with caramelized spots. The vegetables should smell intensely sweet and smoky when done. Let them cool slightly before handling - they'll be delicate when hot.

While the vegetables roast, make the aioli by blending 0.5 cup mayonnaise, 2 tbsp lemon juice, 2 cloves minced garlic, 0.5 tsp salt, and 0.25 tsp black pepper in a food processor until completely smooth. Add the 4 whole anchovy fillets (drained if packed in oil) and process until fully incorporated, about 30 seconds.

The aioli should be thick and silky with a subtle salty depth from the anchovies. Taste and adjust seasoning - you might need a touch more lemon or salt to balance the richness. Keep this mixture at room temperature until ready to use.

Drain the thinly sliced yellow onion if you soaked it earlier, then gently toss with the roasted vegetables. Add the 4 whole Roma tomatoes halved and seeded along with the remaining 0.25 cup extra-virgin olive oil and remaining 0.25 tsp smoked paprika. The vegetables should still be warm from roasting.

Drizzle the anchovy aioli generously over the vegetables and toss gently with tongs to coat everything evenly. The heat from the vegetables will help the aioli emulsify beautifully, creating that signature creamy texture. Sprinkle with 0.25 cup chopped fresh parsley just before serving to keep it vibrant.

Divide the salad among 4 plates and serve while still warm from the roasting. The contrast between the smoky roasted vegetables, creamy anchovy aioli, and fresh parsley creates the perfect balance of textures and flavors. For extra crunch, you can add toasted pine nuts or almonds if you have them on hand.

This salad tastes best when served immediately after assembly while the vegetables retain their crisp-tender texture. The flavors meld beautifully as you eat, with the smoky paprika and salty anchovies complementing the sweet roasted vegetables perfectly. Enjoy with crusty bread to soak up every last bit of that delicious aioli!

Dietary considerations for these flavors

Vegetarian-Friendly Base

The traditional Catalan salad is naturally vegetarian, relying on roasted eggplant, peppers, onions, and tomatoes as its foundation. These vegetables provide a hearty, satisfying base packed with fiber, vitamins A and C, and antioxidants. The dish is already plant-forward, making it perfect for vegans or anyone avoiding meat. 🌱

Anchovies Optional

While anchovies add a briny depth, they're completely optional in this recipe. For a fully vegetarian version, simply omit them from the aioli and boost the lemon juice to 3 tbsp for extra brightness.

The roasted vegetables and garlic still deliver rich, umami flavor without any seafood. I often make this version when hosting vegan guests—they never miss the anchovies!

Gluten-Free Naturally

This salad contains no gluten-containing ingredients, making it safe for those with celiac disease or gluten sensitivity. The aioli base uses mayo, which is typically gluten-free, but always check your brand.

The roasted vegetables and olive oil are naturally gluten-free, so you can enjoy this dish worry-free. For extra assurance, use a certified gluten-free mayo like Hellmann's Gluten Free.

Low-Carb Adaptation

For a lower-carb version, reduce the eggplant to ½ lb and omit the onions entirely. The bell peppers and tomatoes still provide natural sweetness while keeping carbs in check.

This adaptation works well for keto diets while maintaining the dish's signature flavors. The aioli remains unchanged, providing healthy fats to complement the vegetable base.

Allergen Considerations

This salad contains no common allergens like dairy, nuts, or soy, making it suitable for most allergy-sensitive diets. The only potential concern is anchovies, which are fish. For those with seafood allergies, use a vegan anchovy substitute like Miyoko's Vegan Fish Sauce in the aioli.

Always check ingredient labels, especially for the mayo and smoked paprika, which might contain trace allergens.

Meal Prep Flexibility

The roasted vegetables can be prepared up to 4 days in advance and stored in an airtight container, making this salad ideal for meal prep. Keep the aioli separate until ready to serve to maintain freshness.

This flexibility makes it perfect for busy weeks while still delivering restaurant-quality flavors. The components reheat beautifully, ensuring consistent taste even when prepared ahead.
