Lemon Olive Oil Salad Dressing (Light and Low Calorie)

Jump to Recipe

I make this lemon olive oil salad dressing at least twice a week, and I’m not exaggerating when I say it’s changed how I eat salads. Before I discovered how ridiculously easy homemade dressing is, I was buying bottles from the store that were loaded with sugar and weird preservatives. Now?

I whip this up in literally 5 minutes, keep it in a mason jar in my fridge, and use it on everything from simple greens to grain bowls to roasted vegetables.

The best part is that you probably have all the ingredients in your pantry right now. This isn’t one of those recipes where you need to hunt down specialty items. Just good olive oil, fresh lemon juice, Dijon mustard, garlic, and salt and pepper. That’s it. And the result is a bright, tangy, restaurant-quality dressing that makes you actually excited to eat your salad.

Why This Recipe Works

This lemon olive oil dressing hits all the right notes, and here’s why it works so well:

It’s perfectly balanced. The Dijon mustard isn’t just for flavor—it’s the secret ingredient that helps emulsify the dressing so the oil and lemon juice actually stay mixed together instead of separating. Total game-changer.

The garlic adds depth. Just one small clove gives the dressing a subtle savory note without being overpowering. I use fresh garlic because it makes such a difference, but garlic powder works in a pinch.

It’s incredibly versatile. I use this on basic green salads, drizzle it over roasted veggies, toss it with pasta salad, and even use it as a marinade for chicken. Once you have it in your fridge, you’ll find yourself reaching for it constantly.

You control the ingredients. No added sugar, no gums or fillers, no ingredients you can’t pronounce. Just real food that tastes amazing.

It keeps beautifully. Unlike some homemade dressings that only last a few days, this one stays fresh in the fridge for up to two weeks. I make a batch on Sunday and use it all week long.

Ingredient Notes & Substitutions

Extra Virgin Olive Oil: This is the star of the show, so use good quality olive oil. It doesn’t have to be super expensive, but it should taste good on its own since the flavor really comes through. I usually use a medium-bodied olive oil—not the really peppery, intense kind.

Fresh Lemon Juice: Please use fresh lemons, not the bottled stuff. You’ll need about 2 medium lemons to get ¼ cup of juice. The fresh citrus makes all the difference. Pro tip: roll the lemon on the counter with your palm before cutting—you’ll get way more juice out of it.

Dijon Mustard: The Dijon is crucial for emulsification and adds a nice subtle tang. If you only have yellow mustard, it’ll work but the flavor will be slightly different. Whole grain mustard is delicious too if you want a rustic texture.

Garlic: One small clove is perfect. If you love garlic like I do, you can add a second clove, but start with one first. No fresh garlic? Use ¼ teaspoon garlic powder instead.

Salt and Pepper: I use fine sea salt and freshly cracked black pepper. Start with the amounts in the recipe and adjust to your taste.

Honey (Optional): Not in the base recipe, but if you like a touch of sweetness to balance the acidity, add ½ teaspoon of honey. It’s especially good if your lemons are super tart.

Step-by-Step Instructions

Step 1: Mince your garlic clove really finely. I use a microplane grater for this because it creates a paste-like consistency that distributes better in the dressing. If you’re using a knife, chop it as fine as you can.

Step 2: Add the lemon juice, Dijon mustard, minced garlic, salt, and pepper to a jar with a tight-fitting lid. I use a pint-sized mason jar because it’s the perfect size and easy to shake. Before you add the oil, give these ingredients a quick whisk or stir to combine.

Step 3: Pour in the olive oil. Here’s where the magic happens. Put the lid on your jar and shake vigorously for about 30 seconds. You’ll see the dressing transform from separated oil and lemon juice into a creamy, emulsified mixture. This is the Dijon mustard doing its job!

Step 4: Taste and adjust. This is important—dip a piece of lettuce into the dressing and actually taste it. Need more lemon? Add a squeeze. Want it saltier? Add a pinch. Prefer it less tart? Add that optional ½ teaspoon of honey. Make it perfect for YOUR taste.

Step 5: Store it in the fridge for up to 2 weeks. The oil will solidify when cold, which is totally normal. Just let it sit on the counter for 10-15 minutes before using, or run the jar under warm water for a minute. Give it a good shake before each use since natural separation is normal.

Recipe Tips & Tricks

Storage: Keep the dressing in an airtight container (I love using mason jars) in the refrigerator. It will last for 2 weeks, though mine never makes it that long because we use it so quickly.

The Oil Will Solidify: Don’t freak out when you pull your jar out of the fridge and the olive oil has turned cloudy and thick. This is completely normal! Just leave it at room temperature for 10-15 minutes and it’ll return to liquid form. You can also place the jar in a bowl of warm water to speed this up.

Shake Before Using: The dressing will naturally separate as it sits. This doesn’t mean it’s bad—just give it a really good shake for 10-15 seconds before drizzling it on your salad.

Make a Double Batch: This recipe is so easy and keeps so well that I often double it. It’s just as easy to make 2 cups as it is to make 1 cup, and you’ll have dressing for two weeks of salads.

Adjust the Ratio: The classic vinaigrette ratio is 3 parts oil to 1 part acid (lemon juice in this case). If you like your dressing more tart, go with 2 parts oil to 1 part lemon. If you prefer it milder, stick with the 3:1 ratio.

Use a Jar for Easy Emulsification: While you can whisk this in a bowl, using a jar makes it so much easier. The shaking action creates a better emulsion than whisking, and you can store it in the same container. Less dishes!

Variations & Add-Ons

Herb Version: Add 2 tablespoons of finely chopped fresh herbs like basil, parsley, dill, or oregano. This makes it perfect for Greek salads or tomato salads.

Creamy Lemon Dressing: Whisk in 2 tablespoons of Greek yogurt or mayonnaise for a creamy version. It’s amazing on wedge salads or as a veggie dip.

Spicy Kick: Add a pinch of red pepper flakes or a tiny dash of cayenne pepper. I love this on kale salads or roasted vegetable bowls.

Italian Style: Add ½ teaspoon of dried Italian seasoning and a tablespoon of grated Parmesan cheese. Shake it up and you’ve got an Italian vinaigrette.

Shallot Version: Replace the garlic with 1 tablespoon of finely minced shallot for a milder, sweeter flavor. This is super elegant for dinner parties.

Extra Citrus: Use half lemon juice and half lime juice for a different citrus profile. Or try Meyer lemons when they’re in season—they’re sweeter and less tart.

What to Serve With This

This lemon olive oil dressing is incredibly versatile. Here’s what I use it on most often:

Classic Green Salads: Obviously! It’s perfect on mixed greens, arugula, butter lettuce, or spinach salads. I especially love it with a simple salad of romaine, cucumber, tomatoes, and red onion.

Grain Bowls: Drizzle it over quinoa bowls, farro bowls, or Mediterranean rice bowls. The bright lemon flavor cuts through the heartiness of grains perfectly.

Roasted Vegetables: Toss roasted Brussels sprouts, asparagus, or cauliflower with this dressing right when they come out of the oven. The dressing soaks in and adds amazing flavor.

Pasta Salad: Use it as the dressing for cold pasta salads with cherry tomatoes, mozzarella, and fresh basil. It’s my go-to for summer potlucks.

Chicken Marinade: This makes an excellent marinade for grilled or baked chicken. Marinate for at least 30 minutes, or up to 4 hours.

FAQ Section

Can I make this without Dijon mustard?
You can, but the dressing won’t stay emulsified as well and will separate more quickly. The Dijon is really important for keeping the oil and lemon juice mixed together. If you absolutely must skip it, try adding a tiny pinch of xanthan gum, or just plan to shake the dressing vigorously before each use.

How long does this dressing last in the fridge?
It will stay fresh for up to 2 weeks when stored in an airtight container in the refrigerator. Always smell it before using—if it smells off or the garlic has turned bitter, it’s time to make a fresh batch.

Why did my olive oil solidify in the fridge?
This is totally normal! Olive oil solidifies when cold. Just let the jar sit at room temperature for 10-15 minutes before using, or place it in a bowl of warm water. The oil will return to liquid form and you can shake it up and use it normally.

Can I use bottled lemon juice?
I really don’t recommend it. Fresh lemon juice tastes so much better and brighter. Bottled lemon juice has a cooked, flat flavor that just doesn’t compare. Fresh lemons are inexpensive and make all the difference in this recipe.

Can I make this in a blender?
You can, but it’s not necessary and creates more dishes to wash! The beauty of this recipe is that you can make it right in a jar by shaking. If you do use a blender, pulse it a few times rather than running it continuously—over-blending can make the dressing bitter.

Is this dressing healthy?
Yes! It’s made with heart-healthy olive oil, fresh lemon juice, and minimal added salt. Unlike store-bought dressings, it has no added sugars, preservatives, or artificial ingredients. Each serving has about 120 calories, mostly from the healthy fats in olive oil.

What’s the best oil to lemon juice ratio?
The classic vinaigrette ratio is 3:1 (oil to acid). This recipe uses ¾ cup oil to ¼ cup lemon juice, which is the traditional ratio. If you like tangier dressing, try 2:1. If you prefer milder, stick with 3:1.
