Ingredients
Instructions
- Wash and dry all produce. Preheat toaster oven or oven to 400°F. Core, seed and dice the tomato. Peel, halve and thinly slice the onion. Wrap garlic cloves in aluminum foil, sealing to make a pouch, then roast in the oven until very soft, about 20 minutes.
- Heat a drizzle of oil in a large pan over medium heat. Add the onion and cook, tossing, until softened, 4-5 minutes. Season with salt and pepper. Stir in the tomato, 1 teaspoon sugar and 1 tablespoon balsamic vinegar (reserve the rest for later). Cook, stirring, until soft and jammy, 4-5 minutes. Season with salt and pepper. Remove the mixture from the pan and set aside.
- Divide the ground beef in half and flatten each piece into a wide, roughly ½-inch-thick circle. Divide the cheddar cheese between the centers of each circle. Fold the edges of the meat around the cheese, shaping and sealing to create a cheese-stuffed patty. Season all over with salt and pepper.
- Carefully wipe out the pan used for the onion jam with a paper towel, then add a drizzle of oil and heat over medium-high heat. Place the beef patties in the pan and cook to desired doneness, 3-6 minutes per side.
- While the burgers cook, halve the buns and place them on a baking sheet. Toast in the oven or toaster oven until golden brown, 2-3 minutes. Once the garlic is done roasting, mash it with a fork until smooth. In a small bowl, combine ½ tablespoon mayonnaise (you’ll use more later), the remaining balsamic vinegar, a large drizzle of oil and as much roasted garlic as you like. Season with salt and pepper.
- Spread the toasted buns with ketchup and ½ tablespoon mayonnaise (you’ll have some left over). Place the beef patties on the buns and top with the tomato onion jam and a small handful of arugula. Toss the remaining arugula with the dressing in a medium bowl and serve on the side.
Recipe Tips
Make sure to seal the patties well so the cheese doesn’t leak out during cooking.
For extra flavor, let the onion jam cool slightly before topping the burgers.
If you don’t have a toaster oven, you can toast the buns under the broiler for 1-2 minutes.
FAQ
Can I use a different cheese for the stuffing?
Yes, any meltable cheese like mozzarella, provolone or pepper jack works well.
How do I prevent the cheese from leaking out?
Make sure the patty is sealed completely around the cheese and press the edges firmly. Also, avoid overcooking the patty on high heat.
Can I make the tomato onion jam ahead of time?
Absolutely! The jam can be made up to 3 days in advance and stored in the refrigerator. Reheat gently before serving.
