This homemade keto Italian dressing is bright, zesty, and full of savory flavor. It’s a versatile go-to dressing that also doubles as a flavorful marinade.
Making your own dressings is simple and rewarding. This keto Italian dressing comes together in about 10 minutes and uses common pantry ingredients. It’s one of our favorite homemade vinaigrettes — tangy, aromatic, and rich thanks to the addition of Parmesan.
Ingredients that make this keto Italian dressing shine
This dressing starts with olive oil and white wine vinegar. A classic vinaigrette ratio is roughly 3 parts oil to 1 part vinegar, which works well here for a balanced texture and flavor. Dijon mustard helps emulsify the dressing, while finely grated fresh Parmesan adds a savory, creamy depth — I recommend grating it yourself on the smallest holes for the best texture. Dried herbs and seasonings — basil, oregano, parsley, garlic powder, onion powder, red pepper flakes, salt, and pepper — round out the Italian profile. A keto-friendly granulated sweetener such as Swerve adds just a touch of sweetness without carbs.
How easy is it to prepare?
This recipe is quick and straightforward, but a couple of tips will improve the result. Use a good-quality olive oil and white wine vinegar — they don’t need to be expensive, but fresher ingredients produce a brighter dressing. Because this recipe includes finely grated Parmesan, I recommend blending the ingredients in a blender so the cheese fully incorporates. If you prefer shaking in a jar or whisking by hand, the cheese may settle more quickly, so be sure to shake or stir before serving.
Serving suggestions
This Italian dressing is versatile. Use it to dress leafy salads or spinach, toss it with vegetables for roasting or grilling, or mix it into salads like broccoli cauliflower salad or cucumber and tomato salad. It also makes an excellent marinade for chicken, beef, pork, seafood, or turkey, and works well as a finishing drizzle over cooked vegetables or grain-free bowls.

Helpful hints
For best results, finely grate fresh Parmesan and blend the dressing so the cheese incorporates evenly. When refrigerated, the dressing may thicken or solidify; allow it to sit at room temperature for about 30 minutes or warm its container briefly in a warm water bath, then shake or whisk before serving.
