This is a grilled beef burger topped with chimichurri — a punchy Argentine herb sauce made from parsley, oregano, garlic, red wine vinegar, and olive oil. The honest reason to make it: chimichurri takes about five minutes to stir together and does more for a burger than any bottled condiment ever will. Provolone and a toasted brioche bun round it out without overcomplicating things.
What makes this version work
Two things actually move the needle here. First, the chimichurri needs to rest for at least 15 minutes before it hits the burger — the vinegar mellows, the garlic softens slightly, and the oil pulls flavor from the herbs. Make it before you do anything else. Second, shaping the patties slightly wider than your buns matters more than it sounds: beef shrinks inward as it cooks, and a patty that starts the right size ends up smaller than the bun, which throws off every bite. Press a shallow dimple in the center of each patty with your thumb — this counteracts the puffing that happens on a hot grill and keeps the patty flat enough to stack cleanly.
If something goes sideways
- Patties falling apart on the grill: This usually means the beef was handled too much or was too warm. Work the meat as little as possible when shaping, and if your kitchen is warm, chill the formed patties in the fridge for 15 minutes before cooking. Cold fat holds the patty together.
- Chimichurri tastes harsh or too sharp: Too much raw garlic bite or vinegar. Stir in a small pinch of sugar and a splash more olive oil, then let it sit another 10 minutes. The balance shifts quickly.
- Cheese won’t melt properly: Provolone needs a little help. After adding the slice, cover the patty loosely with a metal bowl or a pan lid for the final minute. Trapped steam does the job without overcooking the beef.
- Brioche bun goes soggy fast: Toast the cut sides in a dry pan over medium heat until they’re lightly golden — not just warm. A proper toasted surface resists sauce soak-through for long enough to eat the burger without it falling apart.
- Burger tastes flat despite all the toppings: The patty itself is probably under-seasoned. Salt and pepper only go on the outside, so press them in firmly right before the patties hit the grill rather than mixing them deep into the meat.
Smart swaps
- Provolone: Any semi-firm melting cheese works — Monterey Jack melts more smoothly, mild cheddar adds a sharper note. Avoid fresh mozzarella here; it releases too much water.
- Fresh oregano: If you only have dried, use 1 teaspoon instead of 2 tablespoons — dried oregano is much more concentrated. Skip the egg in the mix — it makes the patty mushy — but do not skip the oregano entirely; it’s what separates chimichurri from plain parsley oil.
- Brioche buns: A potato roll is a solid substitute — slightly less sweet but sturdy enough to hold up. Standard hamburger buns work in a pinch but compress more under the weight of the sauce.
- Red wine vinegar: White wine vinegar is the closest swap. Avoid balsamic — it’s too sweet and will muddy the herb flavors.
Leftovers and meal prep
Chimichurri keeps well in a sealed jar in the fridge for up to 5 days — the oil may solidify slightly when cold, so pull it out 20 minutes before you need it and give it a stir. Cooked patties store in the fridge for up to 3 days; reheat them in a covered skillet over medium-low heat with a splash of water to keep them from drying out. Raw shaped patties can be frozen for up to 2 months — stack them with parchment between each one and seal tightly. Thaw overnight in the fridge before cooking, not on the counter. Do not freeze assembled burgers; the bun turns to mush.
Chimichurri Steak Burger
Ingredients
Burger Ingredients
- 1 pound grass-fed beef preferably 80% lean for juiciness
- 4 slices provolone cheese or cheese of your choice
- 4 medium brioche buns toasted
- 1 teaspoon sea salt
- 0.5 teaspoon ground black pepper freshly ground
Chimichurri Sauce
- 1 cup fresh parsley finely chopped
- 2 tablespoons fresh oregano finely chopped
- 3 cloves garlic minced
- 0.5 teaspoon red pepper flakes
- 0.25 cup red wine vinegar
- 0.5 cup extra virgin olive oil
Instructions
- Prepare the Chimichurri Sauce: In a bowl, combine parsley, oregano, and garlic. Stir in red pepper flakes, red wine vinegar, and olive oil. Mix well, and adjust seasoning to taste. Let the sauce sit for at least 15 minutes to develop flavors.
- Shape the Burger Patties: Gently combine beef with salt and pepper. Divide into four equal portions and shape into patties. Ensure they are slightly larger than the buns as they'll shrink while cooking.
- Grill the Patties: Preheat your grill or skillet to medium-high heat (around 190°C or 375°F). Cook the patties for 4-5 minutes on each side until they reach an internal temperature of 57°C or 135°F for medium-rare, or adjust to your liking. During the last minute, place a slice of cheese on each patty to melt.
- Build the Burger: Lightly toast the brioche buns. On the bottom half of each bun, place the grilled patty with melted cheese. Spoon a generous amount of chimichurri sauce over the top and cap with the top bun.
- Serve: Present the burger with a side of crispy sweet potato fries or a fresh green salad, and consider a Malbec to complement the robust flavors.

Common questions
What internal temperature should the beef patties reach?
For food safety, ground beef should reach 160°F (71°C) internal temperature. That said, if you grind whole-muscle beef yourself at home from a single cut and cook it immediately, medium-rare at 135°F (57°C) carries lower risk — but store-bought ground beef should always hit 160°F.
Can I make the chimichurri ahead of time?
Yes, and it actually improves with time. Make it up to 24 hours in advance and store it covered in the fridge. The flavors knit together better than a freshly made batch.
How do I know when the patties are ready to flip?
Wait until the patty releases cleanly from the grill or pan without sticking — usually around 4 minutes on medium-high heat. If you have to force it, it’s not ready. A patty that sticks is still bonding to the surface and will tear if you rush it.
Do I need a grill, or can I use a stovetop pan?
A cast-iron skillet or heavy stainless pan on the stovetop works just as well. Get it hot before the patties go in — a drop of water should evaporate immediately — and you’ll get a solid sear without a grill.
My chimichurri looks more like a paste than a sauce — what went wrong?
The herbs were probably chopped too finely or the olive oil amount was reduced. Add more olive oil a tablespoon at a time and stir until it loosens to a spoonable consistency. It should pour slowly, not clump.
Can I use pre-made or store-bought chimichurri instead of making it from scratch?
You can, but most jarred chimichurri is noticeably more acidic and less fresh-tasting than homemade. If you go that route, taste it first and stir in a little extra olive oil and a pinch of fresh parsley to brighten it up.
