Ingredients

Makes about 1 1/2 cups (360 ml); 10–12 servings (2 tablespoons each)

• 1 large ripe avocado (about 200 g flesh)
• 3/4 to 1 cup low-fat buttermilk (180–240 ml), start with 3/4 cup
• 1 packed cup fresh cilantro leaves and tender stems (about 25 g; also called coriander leaves)
• 1–2 limes, zested and juiced (2–3 tbsp / 30–45 ml juice)
• 1 small jalapeño, seeded and roughly chopped (optional, for heat)
• 1 small garlic clove
• 1 tablespoon extra-virgin olive oil (optional, for extra richness)
• 1/2 teaspoon kosher salt, plus more to taste
• 1/4 teaspoon ground cumin (optional)
• 1/4 teaspoon freshly ground black pepper
• 1 teaspoon honey or agave (optional, balances acidity)
• 2–4 tablespoons cold water, as needed to thin

Step-by-Step Instructions

1. Prep: Halve, pit, and scoop the avocado. Zest and juice the limes. Roughly chop the cilantro and jalapeño.
2. Build the base: To a blender, add buttermilk, lime juice and zest, garlic, jalapeño, cumin, salt, and pepper. Blend 10–15 seconds until combined.
3. Cream it: Add the avocado and olive oil. Blend until completely smooth and creamy, 20–30 seconds. Scrape down the sides as needed.
4. Adjust: Taste, then add honey if desired. Thin with cold water or more buttermilk, 1 tablespoon at a time, to reach your ideal pourable or dippable consistency. Season with additional salt and lime to balance.
5. Chill: Transfer to a jar. Press parchment or plastic wrap directly on the surface, seal, and refrigerate 15–30 minutes to meld flavors.

Pro Tips for Best Results

• Choose ripe avocados: They should yield slightly to gentle pressure with no sunken spots.
• Pack the cilantro: Include tender stems for more flavor and less waste; avoid thick, woody ends.
• Bright green, longer: Lime juice and surface coverage keep the color vibrant; minimize air contact.
• Dial the texture: Thicker for tacos/veggies, thinner for salads. Water lightens without diluting tang too much.
• Protein boost: Swap half the buttermilk for plain Greek yogurt for a higher-protein, ultra-creamy version.

Common Mistakes to Avoid

• Underripe or oxidized avocado: Leads to bland or brown dressing.
• Over-thinning: Add liquid gradually; it’s easier to thin than to re-thicken.
• Under-salting: Avocado needs adequate salt to pop; taste after chilling and adjust.
• Skipping fresh citrus: Bottled lime tastes flat; fresh juice and zest make a big difference.
• Over-blending until warm: Heat can dull color and flavor. Blend just until smooth.

Essential Tools

• Blender or food processor
• Citrus juicer or reamer and a fine grater/zester
• Measuring cups and spoons
• Airtight jar or bottle (8–16 oz / 240–475 ml)

Flavor Variations

• Extra spicy: Swap jalapeño for serrano or add a pinch of cayenne.
• Smoky chipotle: Blend in 1 teaspoon minced chipotle in adobo.
• Dairy-free: Use 1/2 cup unsweetened almond or cashew milk + 2–3 tablespoons lime juice and 1–2 tablespoons olive oil; thin with water as needed.
• Herb swap: Try parsley + mint for a fresh twist if cilantro isn’t your thing.
• Avocado-lime “ranch”: Add 1/2 teaspoon dried dill and 1/4 teaspoon onion powder.
• Tomatillo boost: Add 1 small raw tomatillo for tangy complexity.

Serving Ideas

• Salads: Chopped romaine, corn, black beans, cherry tomatoes, and grilled chicken.
• Tacos and burritos: Drizzle over grilled fish, shrimp, or carne asada.
• Bowls: Spoon onto rice, quinoa, or cauliflower rice bowls with roasted veg.
• Veggie dip: Serve with cucumbers, bell peppers, jicama, and carrots.
• Grill night: Use as a finishing sauce for salmon, steak, or portobello mushrooms.

FAQ

How long does avocado cilantro lime dressing last?

Stored in an airtight jar, it keeps 3–4 days in the refrigerator. Press parchment or plastic wrap directly on the surface to reduce browning. If it thickens, whisk in a splash of water or buttermilk before serving. Freezing isn’t ideal; the dairy can split and herbs may darken.

Can I make it dairy-free without buttermilk?

Yes. Blend avocado, cilantro, lime juice/zest, garlic, salt, and pepper with 1/2 cup unsweetened almond or cashew milk plus 1–2 tablespoons olive oil. Add extra lime to mimic buttermilk tang and thin with cold water as needed. Vegan yogurt also works for added body.

How do I fix a dressing that’s too thick or too thin?

Too thick: Whisk in cold water or more buttermilk a tablespoon at a time until it flows as you like. Too thin: Blend in more avocado or a spoonful of Greek yogurt to restore body. Always recheck salt and lime after adjusting texture.

What can I use instead of cilantro?

Try a mix of flat-leaf parsley and mint, or parsley with a small handful of basil. Add a pinch of ground coriander seed for a hint of familiar flavor. Increase lime zest slightly to keep the dressing bright and aromatic without cilantro’s distinct taste.

Is this dressing healthy?

It’s nutrient-dense, offering heart-healthy fats from avocado, vitamins from fresh herbs, and calcium from buttermilk. Using low-fat buttermilk keeps calories modest. A 2-tablespoon serving generally ranges 60–90 calories. As always, adjust salt and sweetness to your needs and enjoy in sensible portions.

Can I use bottled lime juice or dried cilantro?

Fresh is best. Bottled lime tastes flatter and can be bitter, while dried cilantro lacks the vivid herbal pop. If you must use bottled juice, add fresh lime zest to restore brightness. For herbs, swap in parsley and mint rather than using dried cilantro.

Conclusion

This avocado cilantro lime dressing delivers silky texture and lively, tangy flavor in minutes. Keep it on hand to refresh salads, tacos, bowls, and veggies all week. Make it once, tweak it to your taste, and you’ll have a signature house dressing worth repeating.
