Ingredients

• ▢2 medium red peppers whole
• ▢2 tbsp olive oil divided
• ▢½ tsp salt
• ▢¼ tsp pepper
• ▢3 cloves garlic
• ▢¼ cup almonds whole or pieces
• ▢2 tbsp lemon juice
• ▢½ tsp smoked paprika
• ▢Salt and pepper to taste
• ▢1 tbsp cilantro fresh chopped (optional, for serving)

Equipment

• Baking sheet or broiler pan
• Small skillet
• Food processor or high-speed blender
• Measuring spoons and cups
• Knife and cutting board

Taste and texture notes

The romesco should be smooth with a touch of grain from the almonds. Adjust lemon juice for brightness and salt for seasoning. If you prefer a thinner sauce for drizzling, add a teaspoon or two of water or additional olive oil until you reach your desired consistency.

Step-by-step instructions

1. Roast the peppers: Preheat your oven to a high broil or 450°F (230°C). Place the 2 medium red peppers whole on a baking sheet. Brush or rub them with 1 tablespoon of the olive oil so their skin gets oily and will blister evenly. Put the peppers under the broiler or in the hot oven and roast, turning occasionally, until the skins are blackened and blistered on all sides, about 10–15 minutes total depending on your oven.
2. Steam and peel: Transfer the hot peppers to a bowl and cover tightly with plastic wrap or place them in a sealed container for 10 minutes. This traps steam and loosens the skins. After steaming, peel off the charred skin, remove the stems and seeds, and roughly chop the pepper flesh. Set aside.
3. Toast the almonds: While the peppers steam, heat a small skillet over medium heat. Add the ¼ cup almonds (whole or pieces) and toast, stirring frequently, until they are fragrant and lightly browned, about 3–5 minutes. Watch closely so they don’t burn. Remove from heat and allow to cool briefly.
4. Sauté the garlic: In the same skillet, add the remaining 1 tablespoon olive oil and the 3 cloves garlic (whole or roughly chopped). Cook over medium-low heat for 1–2 minutes, stirring, just until the garlic is fragrant and beginning to soften. Do not brown the garlic; remove from heat once fragrant.
5. Combine in a blender or food processor: Add the roasted red pepper flesh, toasted almonds, cooked garlic and olive oil, 2 tablespoons lemon juice, ½ teaspoon smoked paprika, ½ teaspoon salt, and ¼ teaspoon pepper into a food processor or high-speed blender. Pulse until the mixture comes together into a coarse paste.
6. Process to desired texture: Continue blending until the sauce is smooth but still has some body from the almonds. If the sauce is too thick for your liking, add a teaspoon of water or extra olive oil at a time and pulse until it reaches the desired consistency.
7. Adjust seasoning: Taste and add salt and pepper to taste. If you want more brightness, squeeze in a little extra lemon juice. If you’d like more smokiness, add a pinch more smoked paprika.
8. Finish and serve: Transfer the romesco sauce to a serving bowl. Sprinkle the optional 1 tablespoon fresh chopped cilantro over the top if desired. Serve spooned over seared steaks, roasted chicken, or grilled fish. The sauce can also be chilled and used as a dip or spread.

Serving suggestions

• For steaks: Spoon 2–3 tablespoons over each cooked steak just before serving.
• For chicken: Use as a finishing sauce for roasted or grilled chicken breasts or thighs.
• For fish: Gently spoon over broiled or pan-seared fillets for an instantly flavorful plate.
• Vegetarian option: Toss with roasted vegetables, spread on grilled bread, or mix into grain bowls.

Tips and variations

• Substitute hazelnuts or walnuts for almonds if you prefer a different nutty character.
• For a chunkier sauce, pulse fewer times in the food processor.
• Add a pinch of cayenne or a splash of sherry vinegar for extra complexity.
