This is a ground pork burger seasoned with the same herbs used in Italian porchetta — rosemary, sage, fennel, garlic, and lemon zest — then topped with provolone, arugula, tomato, and aioli on a brioche bun. It takes about 70 minutes start to finish and gives you something genuinely different from a standard beef burger. The herb mix does most of the heavy lifting, so even if this is your first time making patties from scratch, the flavor is hard to mess up.
What makes this version work
Two things matter here. First, toasting the fennel seeds before grinding them — even just 90 seconds in a dry pan — wakes up oils that stay flat if you skip it, and those oils are what give the patty its porchetta character. Second, keeping the fat content in your ground pork on the higher side (around 20–25%) is non-negotiable for a juicy result. Lean ground pork will cook up dry and tight no matter how carefully you handle it. Everything else in this recipe is forgiving; those two steps are not.
Common problems and fixes
- Patties falling apart in the pan: This usually means the meat was mixed too little, not too much. The proteins need just enough working to bind. If your mix feels crumbly and loose when you form it, fold it over itself a few more times before shaping.
- Flat, spread-out patties: Ground pork softens faster than beef as it heats. If your kitchen is warm, refrigerate the shaped patties for 20–30 minutes before cooking — they’ll hold their shape much better.
- Cheese sliding off before it melts: Add the provolone slice in the last 60–90 seconds of cooking, then tent the pan loosely with foil. The trapped steam melts it evenly without overcooking the patty.
- Bitter, sharp herb flavor: This happens when dried herbs are substituted at a 1:1 ratio. If you can’t get fresh rosemary or sage, use one-third the amount of dried — they’re much more concentrated.
- Undercooked center with a dark crust: Medium-high heat is right for the crust, but if your patties are a full inch thick, the outside can brown before the inside reaches 160°F (71°C). If that’s happening, drop to medium heat after the first flip and give it an extra 2–3 minutes. Always check with a thermometer — pork must hit 160°F all the way through.
Smart swaps
- Fennel seeds: These are the ingredient most people don’t have. Ground fennel works at the same quantity. In a real pinch, a small amount of anise seed does a similar job, but use half as much — it’s stronger.
- Provolone: Low-moisture mozzarella melts cleanly and keeps the Italian flavor profile. Fontina is another good option. Skip the egg in the mix — it makes the patty mushy and you don’t need a binder here.
- Brioche buns: A standard potato roll works fine and holds up better if your patties are very juicy. Brioche can go soggy fast, so toast it until it’s genuinely golden, not just warm.
- Aioli: Store-bought garlic mayo is a perfectly reasonable shortcut. Stir in a little lemon juice and zest to match the flavors already in the patty.
Make-ahead notes
The seasoned pork mixture can be made and refrigerated up to 24 hours ahead — the herbs actually bloom more fully overnight, which is a genuine improvement. Shaped raw patties keep well in the fridge for the same 24-hour window; stack them with parchment between each one. For longer storage, freeze raw patties on a flat tray until solid, then transfer to a zip bag — they keep for up to 2 months. Thaw overnight in the fridge before cooking, never on the counter. Cooked patties reheat best in a covered skillet over low heat with a tablespoon of water to create steam; the microwave works but dries them out quickly.
Italian Porchetta Burger
Ingredients
Porchetta Filling
- 500 grams ground pork preferably with a good fat content
- 2 tablespoons fresh rosemary finely chopped
- 2 tablespoons fresh sage finely chopped
- 3 cloves garlic minced
- 1 teaspoon fennel seeds toasted and ground
- 1 teaspoon lemon zest freshly grated
- 1 teaspoon salt
- 1 teaspoon black pepper freshly ground
Burger Assembly
- 4 medium brioche buns lightly toasted
- 4 slices provolone cheese
- 1 cup arugula fresh and peppery
- 1 cup tomato sliced, preferably heirloom
- ½ cup aioli lemon or garlic, to taste
Instructions
- In a large bowl, combine the ground pork, rosemary, sage, garlic, fennel seeds, lemon zest, salt, and black pepper. Mix gently with your hands until all ingredients are evenly distributed, but do not overwork the meat to keep it tender.
- Divide the mixture into four equal portions. Form each portion into a patty about 1 inch thick. Make a small indentation in the center of each patty with your thumb to ensure even cooking.
- Preheat a grill or skillet over medium-high heat (approximately 190°C / 375°F). Cook the patties for 5-7 minutes on each side or until they reach an internal temperature of 70°C / 160°F and are well-browned.
- During the last minute of cooking, place a slice of provolone cheese on each patty, cover with a lid or aluminum foil, and allow it to melt gently.
- While the burgers rest, lightly toast the brioche buns until golden. Spread a generous amount of aioli on the bottom half of each bun.
- Assemble the burgers by layering arugula, a provolone-topped patty, and tomato slices on the aioli-smeared bun. Cap with the top half of the bun.

Frequently asked questions
Does the pork have to be cooked all the way through — can I leave it a little pink?
Yes, ground pork must reach an internal temperature of 160°F (71°C) with no pink remaining. Unlike a whole-muscle pork chop, ground meat can carry surface bacteria throughout, so a thermometer is the only reliable way to know it’s safe.
Can I use beef instead of pork?
You can, but the flavor profile shifts noticeably — the fennel and sage combination is specifically what makes this taste like porchetta rather than a standard herb burger. If you do use beef, go with 80/20 ground chuck and cook to 160°F (71°C) for a ground patty, or 155°F if you’re using whole-muscle beef you’ve ground yourself.
How do I know when to flip the patty?
Flip once, when the patty releases cleanly from the pan without sticking — usually around the 5-minute mark on medium-high heat. If you have to force it, it’s not ready; a properly seared patty will let go on its own.
My fennel seeds are whole — do I have to grind them?
Grinding them gives a more even flavor distribution through the patty, but whole toasted seeds work too and add a small burst of flavor when you hit one. A quick crush with the flat of a knife is a good middle ground if you don’t have a spice grinder.
