Mini beef burgers

They take 40 minutes of active work, rank as medium difficulty, and cost about €2.30 per person. The onions and sauce are made the night before, leaving only the quick searing for last minute, and the key is salting the patties after cooking to keep the juices in.

These mini burgers disappear in three bites, with a real contrast between the juicy, slightly pink beef, the cheddar melting over the edges, and onions caramelized in balsamic vinegar for a sweet, tangy note. The homemade sauce, a mix of mayonnaise and ketchup with a touch of mustard, ties everything together without covering up the beef.

This is the kind of bite that stands out on a party appetizer spread, for a birthday, a dinner with friends, or a festive family gathering. Serve them as a starter before a simple menu, or as the centerpiece of a finger food buffet alongside other small bites, kids and adults both go for them.

The recipe, moment by moment

The day beforeWhat's better after resting overnight in the fridge.

  1. Slice the onions and cook them slowly over low heat with the butter, sugar, and a pinch of salt until deep golden, then deglaze with balsamic vinegar. 35 min

    Don't rush them, 30 minutes on low heat beats 10 minutes on high.

  2. Mix the mayonnaise, ketchup, and mustard for the burger sauce, and keep it chilled.

    Add a finely chopped pickle to the sauce for extra kick.

The same dayDuring the day, whenever you get a moment.

  1. Divide the meat into 18 patties of 40 g each, flatten them a bit wider than the buns, and place them on a covered tray.

    Don't overwork the meat, the more you handle it, the drier the patty gets.

Before the guests arriveThe last hour, right before the doorbell rings.

  1. Cut the cheddar slices in half, slice the pickles, and warm the onions at the last minute.

    Reheat the onions over very low heat, they shouldn't dry out.

When it's time to serveThe final touches, right in front of your guests.

  1. Sear the patties in a very hot skillet, 2 minutes per side, salt and pepper only once they're off the heat, and top with cheddar to melt. 5 min

    Salt only after cooking, salt draws the juices out of the meat the moment it touches it.

  2. Assemble each bun with a little sauce, the cheddar topped patty, onions, and a pickle slice, then secure with a toothpick.

    Toast the cut side of the buns in the skillet for a minute, they won't get soggy from the sauce.

Our tips to get it right

  • Pick ground beef with 15% fat, leaner meat dries out when seared, fattier meat renders too much and leaves the bun soggy.
  • Let the patties sit out of the fridge for about ten minutes before cooking, they sear better and stay juicier inside.
  • Shape the patties flat and the same size so they all cook at the same rate and the burgers stack up neatly.

The variations

  • Swap the beef for ground veal or pork for a different flavor, keeping the same quantities and cooking time.
  • For a vegetarian version, use store bought bean or vegetable patties instead of beef, keeping the cheddar and caramelized onions.
  • For kids, skip the mustard in the sauce and serve the caramelized onions on the side, some prefer a simpler burger.

What to serve it with

  • Homemade chips or thin fries
  • Simple green salad with vinaigrette
  • Lager beer or craft lemonade

Storage

The caramelized onions and sauce keep for 2 to 3 days in the fridge in a sealed container. Raw shaped patties keep overnight in the fridge, covered with plastic wrap. Avoid freezing assembled burgers, the brioche bun doesn't thaw well.

Questions about this recipe
