Full Ingredients

Core Sauce (makes about 2 cups)

• Roasted red peppers: 12 oz (340 g) from a jar, drained very well, or 2 large fresh red bell peppers (10–12 oz total) roasted and peeled (see Step 1)
• Whole almonds: 1/2 cup (70 g)
• Garlic: 2 medium cloves (about 10 g)
• Sherry vinegar: 1 1/2 tbsp (22 ml)
• Smoked paprika: 1 tsp (2.5 g)
• Extra-virgin olive oil: 1/3 cup (80 ml)
• Kosher salt: 3/4 tsp (about 4 g), plus more to taste
• Freshly ground black pepper: 1/4 tsp

Optional Texture & Flavor Boosters

• Tomato paste: 1 tbsp (16 g)
• Crusty bread (for extra body): 1/2 thick slice (~15 g), torn and lightly fried in 1 tsp olive oil until crisp
• Cayenne: 1/8 tsp for gentle heat
• For garnish/serving bowls: 1 tbsp finely chopped toasted almonds, a pinch of smoked paprika, and a thin drizzle of olive oil

Step-by-Step Instructions

Step 1: Prep the peppers (jarred or roast fresh)

If using jarred: Drain a 12 oz (340 g) jar of roasted red peppers and pat very dry with paper towels for 1–2 minutes to remove excess moisture.

If roasting fresh: Preheat the oven to 475°F (245°C). Place 2 large red bell peppers on a foil-lined sheet. Roast 20–25 minutes, turning once, until skins are blistered and blackened in spots. Transfer to a bowl, cover, and steam 10 minutes. Peel, core, and seed; you should have 280–300 g peeled pepper flesh. Pat dry.

Step 2: Toast the almonds and mellow the garlic

Toast 1/2 cup (70 g) whole almonds in a dry skillet over medium heat, stirring, 4–6 minutes until fragrant and golden in spots (or bake at 350°F/175°C for 8–10 minutes). Transfer to a plate to cool.

In the same skillet, add 1 tsp olive oil and gently sauté 2 garlic cloves over low heat for 60–90 seconds until just fragrant and lightly golden at the edges. Do not brown deeply (it can taste bitter). Cool slightly.

Step 3: Load the blender

To a blender or food processor, add the peppers, toasted almonds, sautéed garlic, 1 1/2 tbsp (22 ml) sherry vinegar, 1 tsp smoked paprika, 3/4 tsp kosher salt, and 1/4 tsp black pepper. Add optional 1 tbsp tomato paste and/or the crisped bread for a thicker, heartier romesco.

Step 4: Pulse to a coarse base

Pulse 10–15 times until the mixture forms a coarse, chunky paste; scrape down the sides as needed. You want visible almond flecks—don’t fully puree yet.

Step 5: Emulsify with olive oil

With the machine running, drizzle in 1/3 cup (80 ml) olive oil in a slow, steady stream over 30–60 seconds until the sauce thickens, turns glossy, and is spreadable. If it’s too thick, blend in 1–2 tbsp cold water; if too loose, add a few more almonds or the optional bread and pulse.

Step 6: Season, rest, and store

Taste and adjust: add a pinch more salt, an extra 1–2 tsp vinegar for brightness, or a tiny pinch of cayenne for heat. Let the sauce rest 10 minutes so flavors meld. Transfer to a clean jar or small bowls. For presentation, swirl the top, add a light drizzle of olive oil, a pinch of smoked paprika, and a few chopped almonds.

Pro Tips

• Dry the peppers thoroughly—excess liquid makes romesco watery. Patting dry is a small step with big impact.
• Sautéing garlic briefly tames harshness. Prefer a punchier bite? Use 1 clove raw and 1 clove sautéed.
• Control texture: a blender yields silky; a food processor gives a rustic, spoonable spread with almond flecks.
• Balance is key: if it tastes flat, add a pinch of salt; if heavy, brighten with 1–2 tsp more sherry vinegar.
• If the emulsion breaks or separates, blend in 1 tsp cold water to bring it back together.

Variations

• Hazelnut Romesco: Swap almonds for toasted hazelnuts; peel skins by rubbing in a towel after toasting for a smoother finish.
• Smokier & Spicier: Add 1–2 tsp Calabrian chili paste or 1/4 tsp hot smoked paprika in place of some sweet smoked paprika.
• Tomato-Forward: Blend in 2 tbsp fire-roasted canned tomatoes (well drained) for a slightly looser, brighter sauce.

Storage & Make-Ahead

Refrigerate in a sealed jar up to 7 days. For best freshness, smooth the top and add a thin 1–2 tsp layer of olive oil. Flavor improves after a few hours in the fridge. Freeze in ice-cube trays or 1/4-cup portions up to 3 months; thaw overnight in the refrigerator and re-blend or whisk to refresh. Bring to room temperature 15–20 minutes before serving for ideal texture.
