This is a blue cheese stuffed beef patty cooked like a grilled cheese sandwich — two slices of buttered bun, American cheese on both sides, the whole thing pressed and toasted on a stovetop grill. It comes together in 30 minutes and uses six ingredients. The reason to make it is simple: you get molten blue cheese inside the patty and melted American cheese outside, which means every bite has cheese in it.
The short version of why this works
Two things carry this recipe. First, the stuffed-patty technique: you press two thin patties together around the blue cheese crumbles and seal the edges firmly so the filling stays trapped during cooking. If the seal is loose, the cheese leaks out and burns on the grill. Second, the grilled-cheese finish: buttering the cut sides of the buns and toasting them directly on the grill gives you a crisp, golden crust that holds up against the juicy patty. That contrast — crunchy outside, molten inside — is what makes this feel like a complete meal rather than just a burger with extra cheese on top. Cook the beef patty to 160°F (71°C) internal temperature; that’s the safe target for ground beef and it still leaves you with a juicy result.
Shopping notes
- Blue cheese crumbles: Pre-crumbled works fine here. Avoid a wedge you crumble yourself unless it’s very cold — warm, soft blue cheese turns to paste and makes the patties harder to seal.
- Ground beef: Use 80/20 (chuck). Leaner beef dries out faster on a stovetop grill and gives you less flavor to balance the sharpness of the blue cheese.
- American cheese slices: The processed kind melts evenly and clings to the bun. Fresh deli-sliced American works too. Skip aged cheddar here — it doesn’t melt the same way and can turn greasy under the lid.
- Burger buns: A standard soft bun is correct. A thick brioche bun will take longer to toast through and can get soggy in the middle before the outside browns.
Troubleshooting
- Blue cheese leaks out during cooking: The seal around the patty edge wasn’t tight enough. Next time, pinch and press the seam all the way around, then run your thumb along it a second time. Chilling the patties for the full 10 minutes also helps the fat firm up and hold the shape.
- Bun burns before the cheese melts: Your grill is too hot. After cleaning off the burger grease, let the surface cool for a minute before putting the buns down. Medium heat is enough — the lid traps steam and does the melting work.
- Patty is dry in the center: The two individual patties were too thick before stuffing. Each half should be no more than a quarter-inch thick so the total stuffed patty cooks through quickly without drying out the edges.
- Cheese inside didn’t melt: The patty needed more resting time on the plate before you cut in. Give it 2–3 minutes off the heat; the residual heat inside the patty finishes melting the blue cheese filling.
- Sandwich falls apart when flipped: The patty shifted when you flipped the whole assembly. Press down lightly with a spatula to compress everything before the flip, and use a wide spatula so the bun doesn’t overhang.
Storage and reheating
Store leftover assembled sandwiches wrapped tightly in foil in the fridge for up to 2 days. Reheat in a skillet over medium-low heat with a lid on for about 4–5 minutes per side — this re-crisps the bun and warms the patty through without making it rubbery. Avoid the microwave; it steams the bun soft and the cheese turns grainy. If you want to freeze, freeze the cooked patties only (not assembled), wrapped individually, for up to 2 months. Thaw overnight in the fridge before reheating. Skip the egg in the mix — it makes the patty mushy — and the same logic applies here: keep the patty simple so it reheats cleanly.
Blue Cheese Stuffed Burger Grilled Cheese
Equipment
- Stovetop grill pan or flat griddle
- Instant-read thermometer
- Large mixing bowl
- Spatula (wide, sturdy)
- Lid or dome cover for the grill pan
- Butter knife
Ingredients
- 1 pound ground beef 450g, 80/20 blend recommended
- ½ cup blue cheese crumbles 70g
- 2 whole burger buns brioche or potato rolls work best
- 4 slices American cheese about 85g / 3oz total
- ¾ teaspoon kosher salt adjust to taste
- ½ teaspoon ground black pepper
- 2 tablespoons unsalted butter 28g, softened, for the buns
Instructions
- Add salt and pepper to ground beef. Combine well.1 pound ground beef, 3/4 teaspoon kosher salt, 1/2 teaspoon ground black pepper
- Divide the seasoned beef into 4 equal portions (about 115g / 4oz each). Flatten each portion into a thin patty about 5 inches (13cm) wide and ¼ inch (6mm) thick — they need to be thin enough to seal together around the filling.1 pound ground beef
- Place about 2 tablespoons of blue cheese crumbles in the centre of one patty, leaving a 1-inch (2.5cm) border around the edges.1/2 cup blue cheese crumbles
- Place a second patty on top and press the edges together firmly, pinching all the way around the seam twice to seal completely. The finished stuffed patty should be about ¾ inch (2cm) thick.
- Repeat with the remaining two patties and blue cheese to make a second stuffed patty. Place both patties on a plate and refrigerate for 10 minutes — this firms the fat and helps the seal hold during cooking.1/2 cup blue cheese crumbles
- Heat your stovetop grill pan or griddle over medium-high heat until a drop of water sizzles on contact, about 3 minutes.
- Place the patties on the hot grill and cook for 4–5 minutes per side until they reach an internal temperature of 160°F / 71°C (the safe minimum for ground beef). Use an instant-read thermometer inserted into the side of the patty to check.
- Transfer the cooked patties to a plate and let them rest for 2 minutes so the molten blue cheese settles slightly and stays inside when you bite in.
- Wipe the grill surface clean with a paper towel (careful, it’s hot). Spread butter on one side of each bun half. Place two bottom bun halves butter-side down on the grill over medium heat.2 whole burger buns, 2 tablespoons unsalted butter
- Immediately place one slice of American cheese on top of each bun half on the grill.4 slices American cheese
- Place a patty on top of each slice of cheese.
- Place one slice of American cheese on top of each burger patty. Spread butter on one side of each top bun half and place them butter-side up on top of the cheese.4 slices American cheese, 2 tablespoons unsalted butter, 2 whole burger buns
- Cover with a lid or dome and grill for 2–3 minutes until the bottom bun is golden and crispy. Carefully flip the entire sandwich using a wide spatula, press down gently, and grill the other side for another 2–3 minutes until golden and the cheese is fully melted.
- Transfer to a cutting board, slice in half diagonally, and serve immediately while the cheese is still molten.

Frequently asked questions
How do I keep the blue cheese from leaking out while the patty cooks?
Seal the edges of the two patties firmly by pinching and pressing all the way around the seam twice. Refrigerating the stuffed patty for 10 minutes before cooking also helps the fat firm up so the seal holds under heat.
What internal temperature should the patty reach?
Cook ground beef to 160°F (71°C) internal temperature. Use an instant-read thermometer inserted into the side of the patty to check — this is the only reliable way to know it’s safe and still juicy.
Can I make this on an outdoor grill instead of a stovetop grill pan?
Yes, but the grilled-cheese step is trickier outdoors. You’d need a cast iron skillet or griddle on the grill grates to toast the buns and melt the outer cheese slices the same way.
How much blue cheese should I put inside each patty?
About 1 to 2 tablespoons of crumbles per patty is enough. More than that and the patty is hard to seal, and the filling can make the center of the burger taste overwhelmingly sharp.
Can I swap the American cheese for something else?
Provolone or mild cheddar will melt reasonably well, but American cheese is the most reliable choice for even, gooey coverage. Stronger cheeses like sharp cheddar can turn oily when heated under a lid.
Do I need to butter both sides of each bun half?
Only the cut side that goes face-down on the grill needs butter — that’s the side that toasts. The outer top gets buttered too so it browns when you flip the whole sandwich, giving you a crisp shell on both sides.
