Bottled salad dressing is one of the easiest food expenses to eliminate and barely notice the difference, except in the wrong direction. Homemade salad dressing tastes noticeably better, costs a fraction as much, and takes about three minutes with no cooking. Knowing how to make homemade salad dressing means the salad you make at home is never the sad, underdressed version you have to eat before the main course arrives.
The ratio for any vinaigrette is three parts oil to one part acid. Everything else is optional. Three tablespoons of olive oil to one tablespoon of vinegar produces a balanced dressing that works on most salads. That ratio is the foundation. Once you know it, you can improvise indefinitely without measuring.
The oil matters. Extra virgin olive oil has enough flavor to be the backbone of the dressing. A neutral oil like grapeseed or avocado oil is a better choice if you want the other flavors to come through more clearly, particularly with very acidic vinegars or strong add-ins like blue cheese or anchovy. For most everyday salads, good extra virgin olive oil is the right call.
The acid determines the character of the dressing more than any other ingredient. Red wine vinegar is assertive and pairs well with bitter greens like arugula and radicchio. White wine vinegar is lighter and works with delicate lettuces. Lemon juice is bright and pairs well with herbs. Apple cider vinegar has a mild sweetness that works in honey-mustard style dressings. Balsamic vinegar is rich and slightly sweet and works well on its own with just oil and a pinch of salt.
To emulsify the dressing so it stays combined instead of separating immediately, add half a teaspoon of Dijon mustard. The mustard acts as an emulsifier and also adds a mild heat. Whisk the mustard and vinegar together first, then add the oil in a thin stream while whisking. The dressing will come together in a cohesive texture that clings to leaves rather than pooling at the bottom of the bowl. A garlic clove minced or smashed adds depth. A pinch of salt and black pepper is non-negotiable.
A simple formula that covers most occasions: one tablespoon of Dijon mustard, two tablespoons of red wine vinegar, one small clove of garlic minced, half a teaspoon of honey, six tablespoons of extra virgin olive oil, salt and pepper to taste. Whisk everything except the oil, then add the oil slowly while whisking. Taste it on a leaf of lettuce rather than on its own, since the acidity reads differently when it is coating something. Adjust salt if needed.
Make a larger batch and store it in a jar in the refrigerator for up to a week. The olive oil will solidify slightly when cold. Take it out ten minutes before using or shake it vigorously and it returns to its original texture. This dressing works on simple green salads, on roasted vegetables as a warm drizzle, and as a marinade for chicken or fish. Paired with the guide on crispy roasted vegetables, it completes a side dish that takes under thirty minutes total. A quick salad with this dressing alongside a plate of crispy quesadillas or a bowl of homemade chili rounds out any weeknight dinner.
Eliminating three or four bottled dressings from your weekly grocery list is a small change that adds up over a month. The Family Budget Reset has a section on identifying these types of swaps across your grocery list, where from-scratch options cost less and taste better, making them easy wins rather than sacrifices. Make a jar of this dressing on Sunday and your weeknight salads take thirty seconds rather than thirty minutes. Our guide on stretch ground beef is worth a read alongside this one.
