Roasted Red Pepper Sauce Recipe
Introduction
This roasted red pepper sauce is a vibrant and flavorful addition to many dishes. Smooth, creamy, and packed with the sweetness of roasted peppers and the richness of Parmigiano Reggiano, it’s perfect for pasta, sandwiches, or as a dip.

Ingredients
- 2 large red bell peppers
- 1 garlic clove
- ½ cup (50 grams) freshly grated Parmigiano Reggiano cheese
- 10 fresh basil leaves
- ½ teaspoon salt (or to taste)
- 3 tablespoons extra virgin olive oil
Instructions
- Step 1: Preheat oven to 425°F (220ºC).
- Step 2: Wash the peppers and place them in one layer on a baking sheet.
- Step 3: Roast in the oven for 20 minutes until the peppers are blistered in spots.
- Step 4: Using tongs, flip the peppers and roast for another 10-15 minutes until they are at least 50% blackened.
- Step 5: Remove from the oven and cover with parchment paper and a kitchen towel to steam for 10-15 minutes, helping loosen the skins.
- Step 6: Peel off and discard the skins from the peppers.
- Step 7: Make a slit lengthwise on the peppers and remove the stalk along with most seeds. Scrape away any remaining seeds, then roughly chop the pepper flesh.
- Step 8: Peel the garlic clove, cut it in half, and remove the germ (the light green sprout in the center).
- Step 9: In a food processor or blender, combine the roasted peppers, Parmigiano Reggiano, garlic, basil, and salt. Blend while gradually adding the olive oil until the sauce is thick, smooth, and creamy.
- Step 10: Taste the sauce and adjust seasoning as needed.
Tips & Variations
- For a smoky flavor, you can char the peppers directly over a gas flame before roasting.
- Substitute fresh basil with a handful of fresh parsley or oregano for a different herbal twist.
- Add a pinch of red pepper flakes if you like some heat in your sauce.
- If the sauce is too thick, blend in a bit of water or extra olive oil to reach your desired consistency.
Storage
Store the sauce in an airtight container in the refrigerator for up to 4 days. To reheat, warm gently in a small saucepan or microwave until heated through, stirring occasionally. You can also freeze the sauce for up to 2 months; thaw overnight in the fridge before using.

FAQs
Can I use jarred roasted red peppers instead of roasting fresh ones?
Yes, jarred roasted red peppers can be used for convenience. Drain them well before blending, but keep in mind the flavor may be less smoky and fresh than homemade roasted peppers.
Is this sauce suitable for vegans?
This recipe includes Parmigiano Reggiano cheese, which is not vegan. To make it vegan, substitute the cheese with a plant-based alternative or nutritional yeast, and the sauce will still be delicious.

Ingredients
Main Ingredients
- 2 large red bell peppers
- 1 garlic clove
- ½ cup (50 grams) freshly grated Parmigiano Reggiano cheese
- 10 fresh basil leaves
- ½ teaspoon salt (or to taste)
- 3 tablespoons extra virgin olive oil
Instructions
- Preheat Oven: Preheat your oven to 425°F (220ºC) to prepare for roasting the peppers.
- Prepare Peppers: Wash the red bell peppers thoroughly and place them in a single layer on a baking sheet.
- Initial Roasting: Roast the peppers in the oven for 20 minutes until the skin starts to blister.
- Flip and Continue Roasting: Using tongs, flip the peppers over and roast for another 10-15 minutes, ensuring that at least half of the pepper skin is blackened for a smoky flavor.
- Steam Peppers: Remove the sheet from the oven and cover the peppers with parchment paper and a kitchen towel to steam for 10-15 minutes, helping the skins to loosen.
- Peel Peppers: Once cooled, peel off and discard the skins of the peppers carefully.
- Deseed and Chop: Make a lengthwise slit in each pepper, remove the stalk and most seeds, and scrape away any remaining seeds. Roughly chop the pepper flesh.
- Prepare Garlic: Peel the garlic clove, cut it in half, and remove the germ—the green sprout in the center—to avoid bitterness.
- Blend Sauce: Place the roasted peppers, grated Parmigiano Reggiano, garlic, basil leaves, and salt into a food processor or blender. Gradually add olive oil while blending until the mixture turns thick, smooth, and creamy.
- Adjust Seasoning: Taste the sauce and adjust the salt or olive oil as needed for perfect balance.
- Serve: The sauce yields approximately 1 ¾ cups and can be used immediately or stored for later as a delicious condiment or pasta topping.
Notes
- To easily peel the peppers, steaming after roasting is key; do not skip covering with parchment and towel.
- Removing the garlic germ reduces bitterness and yields a cleaner garlic flavor.
- Use high-quality extra virgin olive oil for the best flavor and texture.
- This sauce can be stored in the refrigerator for up to 5 days in an airtight container.
- For a vegan variation, omit the Parmigiano Reggiano or substitute with a vegan cheese alternative.
- If you want a smoother sauce, blend longer or pass through a fine sieve.
