- The correct topping order to prevent a soggy bun
The charcoal-grilled burger is one of the great pleasures of summer. The char, the smoke, the crust — you can't replicate it on a gas grill or a flat top. But most backyard burgers are mediocre: overworked meat, wrong fat ratio, cooked at the wrong temperature. Here's how to do it right.
The Meat
Start with 80/20 ground beef — 80% lean, 20% fat. The fat is flavor. Leaner beef produces dry, flavorless burgers. If you can, grind your own from chuck roast, or ask your butcher for a coarse grind. Pre-packaged ground beef is fine, but avoid anything labeled "extra lean."
The Patty
- Use 6–8 oz of beef per patty — don't go smaller
- Handle the meat as little as possible — overworking makes tough burgers
- Form into a loose ball, then press into a patty about 3/4 inch thick
- Make a slight indent in the center with your thumb — this prevents the burger from puffing up into a ball
- Season generously with kosher salt and black pepper on both sides, right before grilling
- Never season in advance — salt draws out moisture
The Fire
Burgers need high, direct heat. Set up your Firebull lump charcoal for direct cooking at 500–600°F. A full chimney of lit Firebull, concentrated in the center of the grill, will get you there. Let the grate heat up for 5 minutes before the first burger goes on.
The Cook
- Place patties directly over the coals
- Do not press down — you're squeezing out the juices
- Cook 3–4 minutes on the first side without moving
- Flip once — a good crust will release naturally from the grate
- Cook 2–3 minutes on the second side
- Add cheese in the last 60 seconds and close the lid to melt
- Pull at 130°F for medium, 140°F for medium-well
Pitmaster Tip
Pro Tip: Toast your buns cut-side down on the grill for 30–60 seconds while the burgers rest. A toasted bun holds up to the juices and adds a subtle char flavor that ties the whole burger together.
The Build
The order of toppings matters. Bottom bun → sauce → lettuce (acts as a moisture barrier) → tomato → onion → patty with cheese → pickles → top bun with sauce. The lettuce under the patty prevents the bottom bun from getting soggy. The sauce on both buns ensures every bite has flavor.
The Rest
Let the burger rest for 2 minutes after pulling it off the grill. This is the step everyone skips. The juices redistribute during the rest, which means they stay in the burger instead of running out when you bite into it. Two minutes. That's all it takes.
| Doneness | Internal Temp | Description |
|---|---|---|
| Medium-rare | 125–130°F | Pink center, very juicy |
| Medium | 130–140°F | Slightly pink center, juicy |
| Medium-well | 140–150°F | Mostly cooked through, some juice |
| Well done | 160°F+ | Fully cooked, less juicy |
