This is a straightforward homemade Italian dressing made from pantry staples — olive oil, red wine vinegar, dried herbs, garlic, and a little Dijon. The honest reason to make it: it takes 10 minutes, uses one bowl or jar, and tastes noticeably better than bottled versions because you control the oil quality and the salt level.
The technique that matters
Emulsification is the one thing worth getting right here. If you just pour everything in and stir, the oil and vinegar will separate almost immediately. The fix is simple: add the olive oil slowly while whisking constantly, or if you’re using a jar, add the mustard first — it acts as a binder — then add everything else and shake hard for about 30 seconds. The mustard is doing real structural work, not just adding flavor, so don’t skip it. A properly emulsified dressing will look slightly thickened and creamy rather than oily and thin. It will still separate in the fridge, which is normal — a quick shake brings it back together.
About the ingredients
- Red wine vinegar: Aged red wine vinegar is noticeably less harsh than the cheap stuff. If yours smells very sharp straight from the bottle, it will taste sharp in the dressing. White wine vinegar works as a milder substitute.
- Extra virgin olive oil: This is most of the dressing by volume, so the quality matters more here than in a cooked dish where heat dulls the flavor. Use one you’d actually eat on bread.
- Dried oregano: Mediterranean oregano (sometimes labeled Greek or Turkish) is more pungent than the standard supermarket variety. Either works, but you may want to add a little more if using the common kind.
- Honey: Balances the vinegar’s sharpness. Skip it if you prefer a sharper dressing — just taste as you go.
Common problems and fixes
- Dressing tastes too sharp or acidic: Add a small extra drizzle of olive oil and a pinch more salt. Salt softens perceived acidity without making the dressing taste salty.
- Raw garlic flavor is too aggressive: Mince the garlic very finely — almost to a paste — so it distributes evenly rather than hitting in chunks. Alternatively, let the finished dressing sit for 15 minutes before serving; the vinegar mellows raw garlic quickly.
- Dressing is too thin and won’t coat greens: You likely added the oil too fast. Whisk in a small extra half-teaspoon of Dijon to help re-emulsify, or shake the jar vigorously for a full minute.
- Herbs taste dusty or flat: Dried herbs that have been sitting in the cupboard for over a year lose most of their potency. Rub the oregano and basil between your fingers before adding — if you can’t smell them clearly, they need replacing.
- Dressing is bland overall: Taste it on an actual piece of lettuce, not just off a spoon — the dilution effect is real. Adjust salt first, then vinegar, then check the garlic level before adding more of anything else.
Storage and reheating
Store the dressing in a sealed jar or airtight container in the refrigerator for up to 5 days. The olive oil will solidify slightly when cold — that’s normal. Pull it out 5 to 10 minutes before you need it and shake well, or set the jar briefly in warm water to loosen it up. Skip the garnish of fresh herbs on top before storing — not worth the extra dish, and they go limp fast anyway. This dressing doesn’t freeze well; the emulsion breaks and the texture turns grainy. Since it takes 10 minutes to make, there’s no real reason to freeze it.
Classic Homemade Italian Dressing
Equipment
- Whisk
- Medium mixing bowl or sealable jar
- Measuring spoons
Ingredients
- ⅔ cup extra virgin olive oil use high-quality, cold-pressed for best flavor
- ¼ cup red wine vinegar preferably aged
- 1 tablespoon Dijon mustard adds mild heat and emulsification
- 1 clove garlic minced finely or pressed
- 1 teaspoon dried oregano preferably Mediterranean oregano
- ½ teaspoon dried basil optional: use Italian herb blend
- ½ teaspoon fine sea salt adjust to taste
- ¼ teaspoon freshly ground black pepper
- 1 teaspoon honey for a touch of sweetness; optional
Instructions
- In a medium mixing bowl or a large mason jar, combine the red wine vinegar, Dijon mustard, minced garlic, oregano, basil, salt, pepper, and honey.
- While whisking vigorously, slowly stream in the extra virgin olive oil until the dressing emulsifies. If using a jar, seal and shake well until combined and slightly thickened.
- Taste and adjust salt, pepper, or sweetness to your preference. The dressing should be balanced, with a tangy but smooth finish.
- Use immediately, or store in a sealed container in the refrigerator for up to 5 days. Shake well before each use, as natural separation may occur.
Notes
- For a creamy variation, whisk in 1 tablespoon of grated Parmesan cheese or 2 tablespoons of plain Greek yogurt.
- Substitute maple syrup for honey for a vegan-friendly option.
- For enhanced flavor, gently warm the garlic in olive oil before adding to reduce its sharpness.

Common questions
Can I use a blender or food processor instead of whisking?
Yes, and it actually produces a more stable emulsion. Combine everything except the oil, then stream the oil in while the blender runs on low — the result will be thicker and creamier than the hand-whisked version.
Can I use fresh herbs instead of dried?
You can, but use three times the amount since fresh herbs are less concentrated. Keep in mind the dressing won’t keep as long — fresh herbs in an oil-based dressing start to degrade after about 2 days in the fridge.
What’s the oil-to-vinegar ratio, and can I adjust it?
This recipe uses roughly a 2.5-to-1 ratio of oil to vinegar, which is on the milder side for acidity. If you prefer a tangier dressing, pull the oil back to half a cup; if you want it richer and less sharp, add another tablespoon or two of oil.
Is this dressing gluten-free?
All the ingredients listed are naturally gluten-free. Just check your Dijon mustard label, since some brands add trace ingredients — most standard Dijon is fine, but it’s worth a quick look if you’re cooking for someone with celiac disease.
Can I use this as a marinade, and how long should I marinate?
It works well as a marinade for chicken, shrimp, or vegetables. For chicken, 30 minutes to 2 hours is enough — the vinegar will start to break down the texture of the meat if you go much longer, especially with thinner cuts.
My dressing separated in the fridge after just a few hours — is it ruined?
No, separation is completely normal for any oil-and-vinegar dressing without artificial stabilizers. A firm shake for 15 to 20 seconds before serving brings it back together.
