There’s a version of summer cooking that gets overshadowed by everything else happening outside — the longer days, the company, the cold drinks. But the food deserves attention too. And if you’re still reaching for the same bottled marinade you’ve been using for years, it might be time to try something different.
Olive oil and balsamic vinegar are two of the most useful tools you have at a grill. Not just for salads or dipping bread — for actual outdoor cooking. Marinades, bastes, finishing drizzles, glazes. They do real work here, and the results are the kind of thing people ask about.
Here’s how to use them well.
Why Olive Oil Belongs on the Grill
There’s a persistent myth that you shouldn’t cook with good olive oil because of the heat. It’s worth setting that aside. Extra virgin olive oil is actually one of the more stable cooking oils available, and it handles grill temperatures well. What it brings to grilling specifically is flavor — something neutral oils simply can’t offer.
Brushing protein or vegetables with olive oil before they hit the grate serves a practical purpose too. It prevents sticking, promotes even browning, and gives seasonings something to adhere to. A flavored olive oil — garlic, rosemary, lemon, Tuscan herb — does all of that while also building flavor into the food before it even touches the heat.
Building a Marinade
A good marinade has three components: fat, acid, and flavor. Olive oil is the fat. Balsamic vinegar is the acid. Everything else is flavor.
The ratio matters less than the balance. A simple starting point is three parts olive oil to one part balsamic, with whatever aromatics make sense for what you’re cooking — garlic, fresh herbs, a little dijon, black pepper, a pinch of salt. Combine everything, add your protein or vegetables, and give it time. Thirty minutes is enough for fish. A few hours works well for chicken. Overnight is ideal for tougher cuts of beef or pork.
A few combinations worth trying:
For chicken — lemon olive oil, traditional balsamic, garlic, and fresh thyme. The lemon brightens everything, and the balsamic adds just enough sweetness to encourage good caramelization on the grill.
For vegetables — a robust extra virgin, fig balsamic, a little honey, and fresh rosemary. This works especially well on eggplant, zucchini, and bell peppers. The fig balsamic turns jammy when it hits the heat.
For steak — garlic olive oil, aged dark balsamic, cracked black pepper, and a small amount of dijon. Let it sit overnight if you can. The acidity from the balsamic tenderizes the meat and the garlic oil carries the flavor all the way through.
Basting While You Cook
Basting is often skipped because it feels like extra work. It isn’t, really, and it makes a meaningful difference. Brushing meat or vegetables with a mixture of olive oil and balsamic every few minutes as they cook builds up layers of flavor and helps develop a glaze on the outside that you can’t get any other way.
Keep a small bowl nearby with your basting mixture and a pastry brush. A good ratio to work with is equal parts olive oil and balsamic, thinned slightly if needed with a little stock or water. Apply it with a light hand — you want a coating, not a drench.
For fish, baste only in the last few minutes of cooking. It’s more delicate than meat and can overpower quickly.
The Finishing Drizzle
This is the step that most people skip and shouldn’t. A finishing drizzle is applied after the food comes off the grill, not during cooking. The heat is gone, the flavors have settled, and a small amount of good oil or aged balsamic over the top adds a brightness and freshness that no amount of cooking can replicate.
A drizzle of good extra virgin over grilled chicken just before it goes to the table. A few drops of aged balsamic over sliced steak. A swirl of lemon olive oil over grilled vegetables. These are small gestures that make a real difference in how the finished dish tastes.
The key here is quality. A finishing drizzle is not a place for something mediocre. When the oil or vinegar is the last thing to hit the food, it’s also the first thing you taste.
A Few Things Worth Knowing
Don’t use your best aged balsamic in a marinade — heat diminishes the complexity you’re paying for. Save it for finishing. A younger, thinner balsamic is better suited to high-heat applications where it has room to cook down and concentrate.
Pat proteins dry before they go on the grill, even after marinating. Excess liquid on the surface steams instead of sears, which works against the browning you’re after. A paper towel and thirty seconds is all it takes.
Let meat rest after it comes off the heat. A few minutes makes a real difference in how the juices redistribute, and it also gives you time to apply that finishing drizzle before it hits the table.
Summer Cooking at Its Best
The best outdoor meals aren’t complicated. They’re built on good ingredients, a little technique, and the willingness to pay attention to the details. A really good olive oil and a balsamic worth finishing with go a long way toward making that happen.
The grill does most of the work. You just have to give it something worth cooking.
