Step‑by‑Step Instructions for Sweet Onion Salad Dressing
Step 1: Prepare the Ingredients
Begin by roughly chopping one large sweet onion and two cloves of fresh garlic. Aim for uniform pieces to ensure even blending. This sweet onion will be the star of your dressing, providing a delightful flavor. Place the chopped ingredients aside as you get ready for the blending process.
Step 2: Combine Ingredients
In a high-speed blender, add the chopped sweet onion and garlic along with 2 tablespoons of honey (or your preferred sweetener), 1/4 cup of apple cider vinegar, 2 tablespoons of Dijon mustard, and a pinch of sea salt and black pepper. Next, pour in 1/3 cup of extra virgin olive oil to bring richness and creaminess to your Sweet Onion Salad Dressing.
Step 3: Blend Until Smooth
Start blending the mixture on low speed for about 10 seconds, then gradually increase to high speed. Continue blending for 30-40 seconds until the dressing is smooth and creamy. You want a velvety texture that beautifully coats your salads. If necessary, use a spatula to scrape down the sides and ensure everything is well incorporated.
Step 4: Taste and Adjust
Taste your Sweet Onion Salad Dressing and adjust the seasoning as desired. If you prefer a sweeter dressing, add more honey; if you like it tangier, incorporate a bit more apple cider vinegar. Blend briefly to combine any adjustments. This will ensure the dressing perfectly suits your palate.
Step 5: Serve and Store
Drizzle the creamy Sweet Onion Salad Dressing over your favorite greens or use it as a dip for fresh vegetables. For best flavor, store any leftovers in an airtight container in the refrigerator for up to one week. Keep it handy for salads or quick meals, relishing the fresh, homemade taste whenever you need it!
