Step‑by‑Step Instructions for Roasted Red Pepper Aioli
Step 1: Roast the Peppers
Preheat your oven to 450°F (232°C). Halve the red bell peppers and remove the seeds, then place them skin-side up on a baking sheet. Drizzle the peppers with olive oil and sprinkle lightly with sea salt. Roast them in the oven for 25-30 minutes, or until the skins are blackened and blistered—this adds a delicious smoky flavor to your Roasted Red Pepper Aioli.
Step 2: Cool and Peel
Once the peppers are roasted, remove them from the oven and allow them to cool for about 10 minutes. This cooling period makes them easier to handle. After cooling, carefully peel off the charred skin, which will come off easily. Be sure to discard any remaining seeds. This step is critical for achieving the smooth texture you’re looking for in your aioli.
Step 3: Blend the Ingredients
In a food processor, combine your peeled roasted red peppers, homemade mayonnaise, garlic, fresh parsley, fresh lemon juice, and a pinch of sea salt. Pulse the mixture until it’s completely smooth and creamy, occasionally stopping to scrape down the sides of the bowl. This blending process marries all the flavors together beautifully, crafting the vibrant Roasted Red Pepper Aioli you’re eager to taste.
Step 4: Taste and Adjust
After blending, take a moment to taste your aioli. You may want to adjust the flavors by adding more salt or a splash of lemon juice for brightness. If you make any adjustments, simply blend again until everything is well incorporated. This final step ensures your Roasted Red Pepper Aioli hits all the right notes of flavor, creating a perfect balance for your palate.

Expert Tips for Roasted Red Pepper Aioli
• Pepper Perfection: Ensure your red peppers are fully roasted until the skins are deeply charred. This brings out their natural sweetness and smokiness, essential for delicious Roasted Red Pepper Aioli.
• Homemade Mayo Wins: For the best texture and freshness, use homemade mayonnaise. Store-bought varieties may alter the aioli’s taste and creaminess.
• Garlic Balance: Start with a small amount of garlic, then taste before adding more. Garlic can be overpowering, so adjust to your preference for the perfect flavor harmony.
• Cooling Process: Allow the roasted peppers to cool adequately before peeling. This step makes skins easier to remove and keeps you safe from burns.
• Chilling is Key: For the richest flavor, let your aioli chill in the refrigerator for at least 30 minutes after blending. This resting period allows the flavors to meld beautifully.
• Storage Savvy: Store your aioli in an airtight container in the refrigerator. It keeps well for up to a week—perfect for making your meals conveniently flavorful throughout the week!
