Step‑by‑Step Instructions for Keto Roasted Red Pepper Aioli
Step 1: Roast Red Peppers
Preheat your oven to 450°F (232°C). Slice the roasted red peppers in half and carefully remove the seeds. Arrange them skin-side up on a baking sheet and generously drizzle with olive oil, then sprinkle with sea salt. The peppers should glisten, signaling they’re ready to roast.
Step 2: Bake until Charred
Place the baking sheet in the oven and roast the red peppers for 25-30 minutes. Keep an eye on them as they roast; the skin should become deeply blackened and charred, indicating perfect caramelization. This lovely browning enhances the flavor, so don’t rush this step!
Step 3: Cool and Peel
Once roasted, remove the peppers from the oven and let them cool for about 10 minutes. This will make handling easier. After cooling, gently peel off the charred skin, revealing the tender, sweet flesh underneath. Discard the skin before you move on to blending.
Step 4: Blend Ingredients
In a food processor, combine the peeled roasted red peppers with mayo, minced garlic, chopped fresh parsley, fresh lemon juice, and a pinch of sea salt. Pulse the mixture until smooth and creamy; you want a vibrant, silky texture. Scraping down the sides as needed ensures even blending for your roasted red pepper aioli.
Step 5: Serve or Store
Taste your keto roasted red pepper aioli and adjust the seasoning if necessary. Transfer your luscious aioli to an airtight container for immediate use or store it in the fridge to let the flavors develop. It’s perfect for dipping or drizzling and can last up to a week, always ready to elevate your meals!
