Extra virgin olive oil is the one ingredient that turns a good braai marinade into a great one. As a natural emulsifier, it binds herbs, garlic, citrus and spices into a stable coating that locks in moisture and builds flavour — while adding the polyphenols and antioxidants that make it one of the healthiest cooking fats available. Here are five olive oil braai marinades, each designed for a different protein.
Why Extra Virgin Olive Oil Is the Best Marinade Base
The fat-soluble compounds in herbs and spices dissolve in oil, unlocking flavour profiles that water-based or vinegar-only marinades cannot achieve. Extra virgin olive oil adds a second benefit: its monounsaturated fats form a protective layer on the meat surface, reducing sticking on the grill and holding in natural juices during high-heat cooking. The peppery bite of fresh cold pressed olive oil also contributes its own seasoning — oleocanthal, the same anti-inflammatory compound studied in clinical research.
1. Lemon and Herb Chicken Marinade
This is the everyday braai chicken marinade that works every time. Combine a quarter cup of extra virgin olive oil with the juice and zest of one lemon, three crushed garlic cloves, a teaspoon of smoked paprika, a teaspoon of ground cumin, a tablespoon of honey and a generous handful of fresh thyme leaves. Season with salt and coarse black pepper.
Marinate bone-in chicken pieces for four to twelve hours, or boneless portions for two to six hours. Pat dry before placing on the grill. The honey will caramelise, so use a two-zone fire — indirect heat first, then a quick sear to finish.
2. Rosemary and Garlic Lamb Chop Marinade
Karoo lamb and olive oil are a natural pairing. In the Karoo, where O for Olive farms olives at Swartrivier Farm in Prince Albert, lamb has been braai’d over open coals for generations. This marinade honours that tradition.
Whisk together a third of a cup of extra virgin olive oil, two tablespoons of finely chopped fresh rosemary, four minced garlic cloves, the juice and zest of one lemon, a teaspoon of dried oregano, two tablespoons of red wine vinegar and a teaspoon of Dijon mustard. Add a few torn mint leaves for a classic lamb pairing.
Lamb chops absorb flavour quickly due to their higher fat content. One hour is sufficient; overnight is ideal. Allow chops to reach room temperature before grilling.
3. Balsamic and Worcestershire Steak Marinade
For beef, the marinade needs depth. Combine a third of a cup of extra virgin olive oil with 50 millilitres of balsamic vinegar, 75 millilitres of Worcestershire sauce, 50 millilitres of soy sauce, a tablespoon of brown sugar, three crushed garlic cloves, a tablespoon of Dijon mustard and sprigs of fresh thyme and rosemary.
Marinate steaks for a minimum of thirty minutes and a maximum of twenty-four hours. Over-marinating with acid can break down the muscle fibres and leave the meat mushy. Four to nine hours is the sweet spot.
4. Lemon and Herb Fish Baste
Fish requires a different approach. Rather than a long soak, this is a baste applied during cooking — the traditional South African way, inspired by the Cape snoek braai tradition.
Mix a quarter cup of extra virgin olive oil with the juice and zest of one lemon, two finely minced garlic cloves, two tablespoons of chopped fresh parsley, a tablespoon of fresh dill, a pinch of chilli flakes and sea salt. If using as a marinade rather than a baste, limit marinating time to fifteen to thirty minutes — any longer and the acid will begin to denature the proteins.
Brush the baste onto the fish every few minutes while it cooks. The olive oil prevents sticking and the herbs infuse directly into the flesh as it grills.
5. Mediterranean Vegetable Marinade
Vegetables need a generous coating of oil to prevent drying out on the grill. Whisk together half a cup of extra virgin olive oil, three tablespoons of balsamic vinegar, three minced garlic cloves, a tablespoon of chopped fresh rosemary, a teaspoon of smoked paprika and a teaspoon of honey. Season well.
The best vegetables for the braai are red bell pepper, baby marrow, brinjal, red onion, portobello mushrooms, butternut and mealies. Marinate for thirty minutes to two hours. Thread smaller pieces onto skewers or use a braai grid to prevent them falling through the grate.
Marinating Times at a Glance
Chicken (bone-in): 4 to 12 hours. Chicken (boneless): 2 to 6 hours. Lamb chops: 1 to 24 hours. Beef steak: 30 minutes to 24 hours. Fish: 15 to 30 minutes only. Vegetables: 30 minutes to 2 hours.
Every one of these marinades starts with the same foundation: good cold pressed extra virgin olive oil. At O for Olive, ours is produced at Swartrivier Farm in Prince Albert — the heart of the Karoo, where lamb, olives and open-fire cooking have always belonged together.
