This burger puts a homemade olive tapenade on a well-seasoned beef patty with crumbled feta and arugula on a toasted brioche bun. The tapenade does the heavy lifting — briny, garlicky, and bright with lemon — so you get a burger that tastes genuinely different without a long ingredient list. If you want something more interesting than your usual cookout burger, this is a practical way to get there.
The short version of why this works
Two things make or break this recipe. First, the patty seasoning: garlic and oregano go directly into the 80/20 beef, which means flavor in every bite rather than just on the surface. Second, the tapenade has to be made before the patties hit the pan — it needs a few minutes for the lemon juice to mellow the raw garlic and let the flavors settle into each other. Rush either of those steps and you end up with a flat-tasting patty under a sharp, unbalanced spread. Get both right and the whole burger clicks.
Mistakes to avoid
- Over-processing the tapenade: Pulse it — don’t run the food processor continuously. A chunky texture holds up on the burger; a smooth paste turns slippery and slides off with every bite.
- Skipping the patty rest: Pull the patties off the heat and let them sit for two minutes before building the burger. Cutting into them immediately loses the juices you worked to keep in.
- Wet arugula: Dry your arugula thoroughly after washing. Water on the leaves dilutes the tapenade and makes the bun soggy fast.
- Too much tapenade: A heaping tablespoon per patty is enough. The olives and capers are salty and concentrated — piling it on overwhelms the beef rather than complementing it.
- Cold feta straight from the fridge: Let the feta sit at room temperature while you cook the patties. Cold crumbles don’t soften at all against the hot patty, and the temperature contrast makes the burger feel unfinished.
Shopping notes
- Kalamata olives: Buy them pitted and packed in brine, not oil — oil-packed olives make the tapenade greasy. Drain and pat dry before using.
- Capers: Standard brine-packed capers work fine. Rinse them briefly to control the salt level, especially if your olives are already quite salty.
- Feta: Buy a block and crumble it yourself. Pre-crumbled feta is drier and less creamy, and it doesn’t distribute as well across the patty.
- Brioche buns: Most grocery bakery sections carry them. If you can’t find brioche, a potato roll is the next best option — skip the egg in the mix — it makes the patty mushy — and focus on a bun with enough structure to hold the tapenade without disintegrating.
Make-ahead notes
The tapenade keeps well in the fridge for up to five days in a sealed container — the flavor actually improves after a day as everything melds together. Shaped raw patties can be refrigerated for up to 24 hours (place parchment between them) or frozen for up to two months; thaw overnight in the fridge before cooking. Cooked patties reheat best in a covered skillet over medium-low heat with a splash of water to create steam, which keeps them from drying out. Avoid the microwave if you can — it toughens the beef. Assemble the burger fresh; the arugula and tapenade don’t hold up once built.
Mediterranean Olive Tapenade Burger
Ingredients
For the Olive Tapenade
- ½ cup Kalamata olives pitted and chopped
- ¼ cup green olives pitted and chopped
- 1 clove garlic minced
- 1 tablespoon capers rinsed and drained
- 1 tablespoon fresh lemon juice
- 2 tablespoons extra virgin olive oil
- ½ teaspoon dried oregano
- ¼ teaspoon black pepper freshly ground
For the Burger Patties
- 1 pound ground beef 80/20 blend for best flavor
- 1 teaspoon garlic powder
- 1 teaspoon dried oregano
- ½ teaspoon salt
- ¼ teaspoon black pepper
- 1 tablespoon olive oil for cooking
For Assembly
- 4 medium brioche burger buns lightly toasted
- ½ cup crumbled feta cheese
- 1 cup arugula
Instructions
- Prepare the Olive Tapenade: In a food processor, combine the Kalamata and green olives, minced garlic, capers, lemon juice, olive oil, oregano, and black pepper. Pulse until the ingredients form a coarse paste. Set aside.
- Make the Burger Patties: In a mixing bowl, combine the ground beef, garlic powder, oregano, salt, and black pepper. Gently mix until just combined, being careful not to overwork the meat. Form into four even patties, pressing a slight indentation in the center to prevent them from puffing up during cooking.
- Cook the Patties: Heat a large skillet or grill pan over medium-high heat. Add olive oil and cook the patties for about 4-5 minutes per side, or until they reach your desired doneness. Remove from heat and let them rest for a couple of minutes.
- Assemble the Burgers: Place the toasted brioche buns on a plate. Layer each bottom bun with a handful of arugula, then place a burger patty on top. Spread a generous amount of the olive tapenade over each patty and finish with a sprinkle of crumbled feta. Cover with the top bun and serve immediately.
Notes
- For a lighter alternative, swap the beef for ground lamb or a plant-based patty.
- You can also add sun-dried tomatoes to the tapenade for additional depth of flavor.

Frequently asked questions
Can I use ground lamb instead of beef?
Yes, ground lamb works well here and pairs naturally with the olive and feta flavors. Cook it to the same 160°F (71°C) internal temperature as ground beef, and expect a slightly richer, more savory result.
How do I know when the patty is done without cutting into it?
Use an instant-read thermometer and pull the patty at 160°F (71°C) internal — that’s the safe target for ground beef. Insert it from the side of the patty through the center for the most accurate read.
Can I make this with a plant-based patty?
A plant-based patty works and the tapenade complements it well since the briny, herby flavors don’t rely on beef drippings. Follow the package instructions for your specific patty — most need to reach 165°F (74°C) internal or be cooked until no pink remains.
