This is a ground beef burger topped with melted provolone and a quick herb sauce made from parsley, cilantro, garlic, red wine vinegar, and olive oil. The sauce does most of the heavy lifting — it’s bright, a little spicy, and cuts through the fat of the beef in a way that ketchup and mustard just don’t. If you’ve got fresh herbs that need using up, this is the right recipe for the week.
The technique that matters
The chimichurri is a no-cook sauce, which means the garlic and vinegar stay sharp and raw — that’s the point. Chop the parsley and cilantro fine so the sauce clings to the patty instead of sliding off in chunks. For the patties, handle the beef as little as possible when shaping them. Overworking ground beef tightens the proteins and gives you a dense, rubbery result. Press a shallow dimple into the center of each patty with your thumb before it hits the heat — this stops the patty from puffing up into a dome as it cooks. Ground beef patties need to reach 160°F (71°C) internal temperature; a cheap instant-read thermometer takes the guesswork out completely.
If something goes sideways
- Chimichurri tastes harsh or too sharp: The vinegar-to-oil ratio is the usual culprit. Add a small splash more olive oil and let the sauce sit for 10 minutes — the flavors mellow as they combine.
- Patties are sticking to the grill or skillet: The surface isn’t hot enough yet. Wait until the pan is fully preheated before adding the patties, and don’t try to move them early — they’ll release naturally once a crust forms.
- Provolone won’t melt evenly: Cover the pan or grill with a lid for the last 60 seconds of cooking. The trapped steam melts the cheese without overcooking the patty.
- Burger is falling apart when you eat it: Too much sauce pooling on the bottom bun is usually the cause. Spread chimichurri on the top bun instead, or add a thin layer of provolone to the bottom bun first to act as a barrier.
- Arugula wilts immediately: Add it right before serving, not during assembly. Heat from the patty will wilt it fast if the burger sits even a few minutes.
Substitutions that actually work
- Cilantro: If you dislike cilantro or don’t have it, just use all parsley. The sauce will be slightly less complex but still very good.
- Red wine vinegar: White wine vinegar or plain apple cider vinegar both work. Avoid balsamic — it’s too sweet and changes the flavor profile entirely.
- Provolone: Low-moisture mozzarella melts similarly and is often cheaper. Monterey Jack is another solid option. Skip pre-shredded cheese — it doesn’t melt as cleanly as slices.
- Arugula: Baby spinach works fine. Shredded iceberg gives crunch without the pepper bite if that’s what you’ve got.
- 80/20 ground beef: This fat ratio genuinely matters for a juicy patty — leaner beef dries out fast on a hot grill. If 80/20 isn’t available, 85/15 is acceptable, but don’t go leaner than that for this recipe.
Make-ahead notes
The chimichurri actually improves after sitting in the fridge for a few hours, so make it up to 24 hours ahead and store it in a sealed jar or container. After about 48 hours the herbs start to dull in color and the garlic gets stronger, so don’t push it much further than that. Raw patties can be shaped, stacked with parchment between them, and refrigerated for up to 24 hours before cooking — or frozen for up to 2 months. Thaw frozen patties overnight in the fridge before grilling. Cooked patties reheat reasonably well in a covered skillet over low heat with a splash of water, but they’ll lose some juiciness, so cook fresh when you can.

Ingredients
Chimichurri Sauce
- 1 cup fresh parsley finely chopped
- ¼ cup fresh cilantro finely chopped
- 3 cloves garlic minced
- 2 tablespoons red wine vinegar
- ½ cup extra virgin olive oil
- 1 teaspoon red pepper flakes adjust to taste
- 1 pinch salt to taste
- 1 pinch ground black pepper to taste
Steak Burger
- 1 lb ground beef preferably 80/20 lean to fat ratio
- 4 medium burger buns toasted
- 4 slices provolone cheese
- 1 cup arugula fresh
- 1 medium red onion sliced into rings
- 1 pinch salt
- 1 pinch ground black pepper to season patties
Instructions
- Prepare the Chimichurri Sauce: In a medium bowl, combine 1 cup of finely chopped parsley, 1/4 cup of chopped cilantro, 3 minced garlic cloves, 2 tablespoons of red wine vinegar, 1/2 cup of extra virgin olive oil, and 1 teaspoon of red pepper flakes. Stir and add salt and pepper to taste.
- Shape the Burger Patties: In a large bowl, mix 1 lb of ground beef with a generous pinch of salt and pepper. Shape into 4 equally-sized patties, each about 3/4 inch thick.
- Grill the Patties: Heat a grill or skillet over medium-high heat. Cook the patties for about 5 minutes per side, or until they reach desired doneness. Add a slice of provolone cheese to each patty during the last minute of cooking, allowing the cheese to melt.
- Assemble the Burgers: Place a handful of arugula on the bottom half of each toasted burger bun, then top with a burger patty. Add a spoonful of chimichurri sauce, a slice of red onion, and top with the other half of the bun. Serve immediately.

Frequently asked questions
Can I use dried parsley instead of fresh?
Dried parsley won’t work well here — the sauce depends on fresh herbs for both texture and flavor. If fresh parsley is the only thing you’re missing, most grocery stores sell it cheaply; it’s worth the trip.
How do I know when the patties are done without a thermometer?
Ground beef patties should reach 160°F (71°C) internally — get a thermometer if you can, because the color of the meat is not a reliable indicator. At roughly 5 minutes per side over medium-high heat, most 3/4-inch patties will be close, but thickness varies.
Can I make this with a leaner ground beef to cut calories?
You can use 85/15, but expect a drier patty. Anything leaner than that and the burger will be noticeably dry, especially on a grill where fat drips away quickly.
My chimichurri turned out very oily — did I do something wrong?
No, that’s normal — chimichurri is an oil-based sauce and it will separate as it sits. Give it a good stir right before spooning it onto the burger.
Can I cook these on a stovetop instead of a grill?
Yes, a cast iron skillet or heavy stainless pan works great. Get it properly hot over medium-high heat before adding the patties, and use the lid trick to melt the cheese at the end.
Is there a bun that holds up better to the chimichurri sauce?
A brioche bun or a potato roll soaks through faster than a standard burger bun — go with a plain toasted bun or a ciabatta roll if you want something that holds its structure. Toasting is non-negotiable with this much sauce.
