Prepare for a flavour explosion with our cheddar-stuffed beef burgers made with lean beef mince and deliciously melty smoked cheddar. Topped with mouthwatering caramelized balsamic red onions, this burger will be sure to impress.
I’m not going to lie. I think this is the best burger recipe I have ever, ever created. Ever. And I’ve made a lot of burgers in my time.
A decent beef burger starts with a good-quality beef mince—like Aberdeen Angus steak mince—the best you can afford, lean if possible.
And cheese.
A burger needs cheese.
This is the way.

- 1 medium brown onion, finely chopped

Instructions
To prepare the caramelized red onions:
- Heat the butter and oil in a skillet over medium heat until it produces a haze.
- Add the finely sliced onions and cook for ten minutes, stirring occasionally. If they start to brown, turn the heat down.
- After ten minutes, sprinkle with a pinch of salt and continue cooking for another 10-15 minutes. When the onions are softened, add the brown sugar and stir well. Add the balsamic vinegar, stir well, and set aside.
To prepare the burgers:
- Meanwhile, heat the butter in a small skillet and gently fry the onion until it softens.
- Stir in the smoked paprika and cook for another minute.
- Transfer to a large bowl and let cool to room temperature.
- Add the beef mince, remaining spices, salt to taste, egg, and tomato puree, and combine well using your hands.
- Divide the mixture into four even balls.
- Press a hole into the centre of each ball using your thumb and place one tablespoon of grated cheese inside.
- Mould the beef mince around the cheese so it is completely encased, then flatten it into a one-inch-thick burger shape. Repeat with the remaining balls.
- Heat a non-stick grill pan over medium-high heat. Fry the burgers on each side for 8-10 minutes, turning only once.
- Serve immediately on toasted burger buns with sliced tomatoes, salad, caramelized red onion, and your desired condiments.
Ground beef contains fat and water; when it is cooked, the juices created by the melting fat and water are released, causing the proteins to shrink. This can result in a burger that shrinks, ending up too small for the burger buns and, frustratingly, too thick to eat easily.
How to stop a beef burger from shrinking
1. Use the best cut of minced beef that you can find with no added water.
2. Cook your burgers over a slow heat, turning them only once halfway.
3. Don’t press the burgers with a spatula when cooking – you want to retain all those tasty juices!
4. Make your burgers slightly larger than you want, as there will inevitably be a slight shrinkage as the meat cooks.
5. Press a little dimple into the centre of the raw beef burger before cooking. This dimple will even out as the burger cooks.
Another common complaint is that beef burgers can be overcooked on the outside yet still undercooked in the middle.
To avoid this, cook your burger over a slow heat and invest in a digital meat thermometer. This avoids the need for guesswork or cutting into the burger (releasing those lovely juices) while cooking to see if the burger is ready.
For a well-done burger, you’re looking for a temperature of 71°C.
Tips for assembling and loading up a beef burger
- Toast your burger buns on the cut side under a grill (or use a bagel setting on your toaster, if you have it).
- To make crispy bacon, place your smoked bacon rashers on a cold grill pan and switch the heat to medium-high. As the bacon heats, it will release fat, which will help it crisp and caramelise nicely. Turn a few times until it’s as crispy as you like, and drain on a kitchen towel before serving.
- Add a slice of cheese to the top of your burgers at the end of cooking before you take them off the heat to rest. The heat of the burgers will melt the cheese nicely, but not too much.
- Add balsamic caramelised red onions (jump to the recipe below).
- For visual appeal, why not serve your loaded-up burger held together with a steak knife, as pictured above?

Yum! Those caramelized red onions look almost better than the burger itself! Now that it’s warming up outside, I can’t wait to GRILL. These burgers would be perfect for a backyard BBQ!
Dannii @ Hungry Healthy Happy
When we ate meat, we always stuffed the cheese inside the burger rather than putting it on pot. It was a nice surprise when you bite in to it.
