How To Make Mega mozzarella-stuffed burgers

A step-by-step guide to this impressive cheese-filled burger.

1. Roast the Onion: Preheat your oven to 180°C/350°F/gas 4, or get your barbecue hot. Wrap the whole red onion in foil and cook it in the oven or directly in the hot coals of a barbecue for 2 hours, until it is completely soft.
2. Make the Basil Mayo: While the onion roasts, make the mayonnaise. Place the egg yolk in a bowl and whisk until fluffy. Very slowly, a tiny drizzle at a time, begin whisking in the olive and vegetable oils. Continue adding the oil in a thin, steady stream while whisking constantly until the mixture is thick and emulsified. Season with a pinch of sea salt and a squeeze of lemon juice. In a pestle and mortar, bash the basil leaves to a paste, then stir this through the mayonnaise.
3. Form the Stuffed Patties: Season the mince well with salt and pepper and mix. Divide it into four equal pieces and shape them into thin, flat patties. Cut the mozzarella ball in half and place one half on top of two of the patties. Place the remaining two patties on top of the cheese-topped ones. Firmly pinch and seal the edges all the way around to completely encase the mozzarella inside, then gently shape each one into a neat burger patty.
4. Make the Balsamic Onions: When the roasted onion is cool enough to handle, peel off the papery skin and discard the root. Mash the soft onion flesh with a fork, then drizzle with the balsamic vinegar and season to perfection with salt and pepper.
5. Cook the Burgers: Get your barbecue or a grill pan nice and hot. Cook the burgers for 8 to 10 minutes, turning regularly, until cooked through and the cheese inside is melted.
6. Assemble and Serve: While the burgers cook, toast the brioche buns on the grill. Crisp up the slices of mortadella on the grill as well. To build your burger, spread a tablespoon of the basil mayo on the bottom bun. Add a thick slice of tomato, a handful of rocket, and a slice of crispy mortadella. Top with the hot, cheese-stuffed burger, a generous dollop of the sticky balsamic onions, and finally the top bun.

Recipe Tips

For the juiciest, cheesiest stuffed burgers every time.

• How to prevent the cheese from leaking out? The most important step is to create a very firm seal around the edges of the two patties. Use your fingertips to pinch the meat together all the way around. Also, avoid pressing down on the burger with a spatula while it’s cooking, as this can force the cheese out.
• Can I make the components ahead of time? Yes! This recipe is great for prepping in advance. The basil mayo can be made and stored in an airtight container in the fridge for up to 3 days. The balsamic onions can also be made ahead and stored in the fridge. You can even form the raw stuffed patties and keep them, separated by parchment paper, in the fridge for up to 24 hours before cooking.
• What’s the best way to make the mayo? The key to a stable, thick mayonnaise is to add the oil extremely slowly at the beginning. Start with just a few drops at a time while whisking constantly. Once it starts to thicken and emulsify, you can add the oil in a thin, steady stream.
• Can I use a different type of cheese? While buffalo mozzarella provides a classic, milky melt, you could also use a low-moisture block mozzarella (which is less watery), provolone, or even a ball of burrata for an extra creamy center.

How To Store Mega mozzarella-stuffed burgers

Keeping your delicious components fresh.

• Refrigerate: It’s best to store the components separately. Leftover cooked burger patties, balsamic onions, and basil mayo should be kept in separate airtight containers in the refrigerator for up to 3 days.
