How To Make Loaded beefburger Recipe
A step-by-step guide to these cheese-stuffed beauties.
- Make the Burger Mixture: In a food processor, add the beef mince, the entire packet of cooked lentils, and half of the cornichons and pickled onions. Season with a pinch of black pepper and blitz until everything is well combined.
- Form and Stuff the Patties: On a large sheet of greaseproof paper, divide the mixture into four equal pieces. Pat each piece out into a 15cm (6-inch) round. In the center of two of the rounds, create a pile with the grated cheese and the remaining finely sliced cornichons, onions, and roasted red pepper.
- Seal the Burgers: Place the remaining two patties on top of the filled ones. Use your fingertips to firmly pinch and seal the edges all the way around, completely encasing the cheesy filling. Gently pat and shape each one into a 3cm-thick burger patty.
- Sear the Burgers: Heat a large, dry non-stick frying pan over a medium-high heat. Brush the patties with olive oil and cook for 1 minute on each side.
- Add Mustard and Finish: Brush the top of each burger with mustard, flip, and cook for another minute. Brush the other side with mustard, flip again, and cook for one final minute. Use tongs to sear the sides of the patties as well.
- Assemble, Halve, and Final Toast: Halve the buns and place a cooked burger inside each one. Now, for the crucial step: cut each assembled burger in half. Place the burgers back in the hot pan, cut-side down, and toast for a final 30 seconds until the inside is golden and gnarly. Serve immediately.

Recipe Tips
For the juiciest, cheesiest stuffed burgers.
- How to keep the cheese from leaking out? The most important step is creating a very firm seal around the edges when you press the two patties together. Pinch the meat tightly with your fingertips to ensure the filling is completely trapped inside.
- Why add lentils to the beef? This is a fantastic trick highlighted in the recipe. The cooked lentils not only make the beef go further, but they also add a wonderful moisture and tenderness to the patties, ensuring a juicy burger every time.
- What is the final “re-toasting” step for? This unique technique is the secret to an incredible texture. Toasting the burger after it’s been cut in half warms the bun through with the beef juices and creates a delicious, “gnarly,” and slightly crispy texture on the cut surface.
- Can I make the patties ahead of time? Yes. You can form and stuff the raw patties, then place them on a parchment-lined plate, cover, and refrigerate for up to 24 hours. This makes for an even quicker dinner.

FAQs
Can I cook these burgers on a barbecue?
Yes, a barbecue would be fantastic. Cook the stuffed patties over a medium-hot grill for about 4-5 minutes per side. You can toast the buns on the grill as well. For the final toasting step, you would need a grill-safe flat top or cast-iron pan.
What’s the best cheese to use for stuffing?
A good, sharp Cheddar that grates well is perfect. However, any good melting cheese like Gruyère, Provolone, or a low-moisture mozzarella would also create a wonderfully gooey, cheesy center.
Can I use something other than lentils?
The lentils are key for the texture described in the recipe. However, you could experiment by blitzing in cooked quinoa, brown rice, or even finely chopped mushrooms to add moisture and bulk to the beef mince.
