  • Easy to customize with spices, cream, or cheese

Ingredients

  • 4 large red bell peppers
  • 1 small onion, chopped
  • 3 cloves garlic, peeled
  • 2 tablespoons olive oil
  • 1/2 cup heavy cream (optional for creaminess)
  • 1/4 cup grated parmesan cheese
  • 1 teaspoon smoked paprika
  • 1/2 teaspoon chili flakes (optional)
  • Salt to taste
  • Black pepper to taste
  • 1/2 teaspoon dried oregano
  • Fresh basil leaves (for garnish)
  • 1/2 cup vegetable broth (for blending consistency)

Instructions

  1. Roast the peppers
    Preheat your oven to 220°C (425°F). Place whole red bell peppers on a baking tray and roast for 25–30 minutes, turning occasionally, until the skins are charred and blistered.
  2. Steam and peel
    Remove the peppers and place them in a bowl covered with plastic wrap or a lid. Let them steam for 10 minutes. This makes the skins easier to peel. Remove skins, seeds, and stems.
  3. Sauté aromatics
    In a saucepan, heat olive oil over medium heat. Add chopped onion and cook until soft and translucent, about 5 minutes. Add garlic and sauté for another minute until fragrant.
  4. Blend the sauce
    Transfer roasted peppers, sautéed onion and garlic, smoked paprika, oregano, chili flakes, and vegetable broth into a blender. Blend until completely smooth.
  5. Simmer and enrich
    Pour the blended mixture back into the saucepan. Stir in heavy cream and parmesan cheese. Simmer on low heat for 5–7 minutes until slightly thickened.
  6. Season and finish
    Taste and adjust seasoning with salt and pepper. Garnish with fresh basil and a drizzle of olive oil.
  7. Serve immediately
    Toss with your favorite pasta or use as a base for other dishes.

Pro Tips for the Best Roasted Red Pepper Sauce

1. Char is flavor
Don’t be afraid of blackened skins—this is where the smoky flavor comes from.

2. Blend thoroughly
For that ultra-smooth restaurant texture, blend for at least 1–2 minutes.

3. Adjust consistency
Add more broth if the sauce is too thick, or simmer longer if too thin.

4. Use quality olive oil
A good olive oil enhances richness and flavor depth.


Variations to Try

1. Vegan Version
Skip the cream and parmesan. Use coconut milk or cashew cream for richness.

2. Spicy Kick
Add extra chili flakes or a roasted chili pepper for heat lovers.

3. Garlic Lover’s Version
Double the garlic for a bold, aromatic punch.

4. Protein Boost
Blend in white beans for added protein and creaminess.
