Dill Red Onion Dressing Ingredients
• Perfect for vibrant salads!
For the Dressing

- 1 tsp coconut sugar – Offers a hint of sweetness to balance the dressing’s acidity; can replace with honey for a more natural sweetener.
- 1/4 tsp dried dill – Contributes herby freshness; fresh dill can be used in equal ratios for more vibrant flavor.
- 4 tbsp olive oil – Acts as the base fat, lending richness; use avocado oil for a different flavor profile.

Step‑by‑Step Instructions for Dill Red Onion Dressing
Step 1: Prepare the Aromatics
Start by finely mincing the red onion and garlic using a sharp knife and a cutting board. Aim for small, even pieces to enhance the dressing’s texture and flavor meld. This process should take about 3-4 minutes. The vibrant color of the red onion will start to stand out, giving you a preview of the dressing’s bright character.
Step 2: Combine the Ingredients
In a clean mason jar or a mixing bowl, combine the minced red onion, garlic, coconut sugar, and dried dill. Pour in the olive oil and white vinegar, and then season with sea salt and pepper to taste. These fresh ingredients blend beautifully, and should take just 2 minutes to prep, filling the space with aromatic hints of dill and onion.
Step 3: Shake or Whisk
Secure the jar lid tightly or grab a whisk for a bowl, and shake or whisk vigorously for about 30 seconds. This action helps to emulsify the olive oil and vinegar, creating a smooth dressing. Look for a slightly thickened consistency and the dressing should turn a light pink hue as the red onion infuses its color.
Step 4: Allow to Marinate
Let the dressing sit for about 5 minutes at room temperature. This short wait allows the flavors to meld and deepen, enhancing the overall taste of your Dill Red Onion Dressing. You will notice the aroma become more pronounced, signaling it’s ready to be enjoyed.
Step 5: Serve or Store
Once marinated, give the dressing one last shake or stir before serving. Use it promptly to elevate salads, roasted vegetables, or grilled meats. If you have leftovers, store them in the refrigerator in a sealed jar for up to a week. Remember to shake again before using, as the ingredients may naturally separate over time.

Expert Tips for Dill Red Onion Dressing
• Choose Quality Oil: Use extra virgin olive oil stored in dark glass to ensure you’re enhancing your dressing with the best flavor and health benefits.
• Mind the Measurements: Be careful when adding salt and sweeteners. Start with less, then adjust to your taste for a perfectly balanced Dill Red Onion Dressing.
• Use Fresh Ingredients: Fresh dill and red onion yield the best flavor. If you opt for dried dill, remember it’s more concentrated, so use less.
• Mix Well: Always shake or whisk the dressing vigorously before serving. This ensures a lovely emulsion where the oil and vinegar blend beautifully.
