This burger puts a seasoned beef patty together with brown-sugar-grilled pineapple, crisp lettuce, and red onion on a toasted bun. The whole thing comes together in about 50 minutes with ingredients you can find at any grocery store. If you like the sweet-savory thing that a good BBQ sauce does, this burger delivers the same payoff without any sauce at all.
The short version of why this works
Two things carry this recipe. First, the brown sugar on the pineapple: it pulls moisture to the surface fast and gives you actual caramelization in just 2–3 minutes per side on a hot grill, not just warm fruit. Use fresh pineapple — canned rings hold too much liquid and steam instead of caramelizing. Second, resting the patties for a full 5 minutes after they come off the grill matters more than it sounds. Ground beef at 160°F is still actively cooking internally; cutting that rest short means juice runs straight out on the first bite. Keep the seasoning simple — skip any fillers like breadcrumbs or egg in the mix, they turn a straightforward patty into something closer to a meatball in texture.
Keeping and reheating
Cooked patties keep in an airtight container in the fridge for up to 3 days. Grilled pineapple is best eaten the same day but will hold refrigerated for about 24 hours before it gets watery. To reheat patties, use a skillet over medium heat with a splash of water and a lid — about 3 minutes — rather than a microwave, which dries them out fast. For freezing, wrap raw shaped patties individually in plastic wrap, then bag them; they’ll keep for up to 3 months. Thaw overnight in the fridge before grilling. Don’t freeze the grilled pineapple; it turns mushy on thawing.
Common problems and fixes
- Pineapple sticks to the grill and tears: Make sure the grates are fully preheated and oiled before the pineapple goes on. Cold or lightly oiled grates grab the sugar coating immediately. A fish spatula works better than tongs for flipping the slices cleanly.
- Patties puff up in the middle while grilling: Press a shallow thumbprint into the center of each raw patty before it hits the grill. The indentation evens out as the meat contracts with heat and you get a flat patty instead of a dome.
- Bun goes soggy before you finish eating: Put the lettuce leaf directly on the bottom bun before the patty — it acts as a moisture barrier between the bun and the hot beef. Don’t skip toasting the buns even lightly.
- Pineapple slices are too thick and stay raw in the middle: Stick close to the half-inch thickness the recipe calls for. Much thicker and the center stays cold and firm while the outside chars. If your pineapple slices are uneven, give the thicker ones an extra minute per side.
- Beef patties falling apart on the grill: This usually means the meat was handled too much or was too warm going on the grill. Mix just until combined, shape quickly, and refrigerate the patties for 15–20 minutes before grilling so they hold together under the heat.
Brazilian Barbecue Pineapple Burger
Ingredients
Patty Mixture
- 500 grams ground beef preferably grass-fed for better flavor
- 1 teaspoon salt
- ½ teaspoon ground black pepper freshly ground
- 1 tablespoon olive oil
Pineapple Slices
- 4 medium pineapple slices fresh, about 1/2-inch thick
- 1 tablespoon brown sugar
Burger Assembly
- 4 medium burger buns lightly toasted
- 4 medium lettuce leaves crisp Romaine or butter lettuce
- 4 slices red onion
Instructions
- In a large bowl, combine the ground beef, salt, and black pepper. Mix gently with your hands until just combined, being careful not to overwork the meat. Divide the mixture into four equal portions and shape into patties about 1.5 cm (1/2 inch) thick.
- Preheat a grill to medium-high heat (about 200°C/400°F). Brush the grates with olive oil to prevent sticking.
- Grill the patties for about 4-5 minutes on each side or until they reach the desired doneness (internal temperature should be at least 71°C/160°F for medium-well). Remove the patties and let them rest for 5 minutes.
- While the burgers cook, sprinkle the pineapple slices with brown sugar. Place the pineapple on the grill and cook for about 2-3 minutes per side or until caramelized and golden.
- To assemble, place a lettuce leaf on the bottom half of each bun, followed by a beef patty, a slice of grilled pineapple, a slice of red onion, and the top bun. Serve immediately.

Your questions, answered
Can I use canned pineapple instead of fresh?
Fresh pineapple works much better here. Canned rings carry extra liquid that prevents the brown sugar from caramelizing properly — you’ll get steamed, soft fruit instead of golden, sticky slices. If fresh isn’t available, drain canned rings thoroughly on paper towels for at least 10 minutes and pat dry before adding the sugar.
What’s the best ground beef fat percentage for this recipe?
80/20 (chuck) is the practical choice — it stays juicy on a hot grill without needing any added fat. Leaner blends like 90/10 tend to dry out quickly at the medium-high heat needed to caramelize the pineapple at the same time.
Can I make this on a stovetop grill pan instead of an outdoor grill?
Yes, a cast-iron grill pan works fine for both the patties and the pineapple. Get it properly hot over medium-high before anything goes in, and run your kitchen fan — the brown sugar produces noticeable smoke indoors.
What can I use instead of red onion if I don’t have any?
Thinly sliced white onion is the closest swap and works well raw. Yellow onion is sharper raw, so if that’s all you have, soak the slices in cold water for 10 minutes to take the edge off before assembling.
How do I know when the patties are done without a thermometer?
Get a thermometer — it’s the only reliable way to confirm ground beef has hit the required 160°F (71°C) internal temperature. A basic instant-read probe costs a few dollars and removes all the guesswork, especially since thickness and grill temperature vary.
Can I prep the patties ahead of time?
Yes — shape the patties, layer them with parchment between each one, and refrigerate for up to 24 hours before grilling. Chilling them actually helps them hold their shape on the grill, so this is a useful step even when you’re not prepping in advance.
