Frequently Asked Questions

What size patty should I use for a smash burger?
The sweet spot is 2.5 to 3 ounces of loosely packed 80/20 ground beef per patty. This size smashes thin enough to develop crispy, lacy edges without drying out. Most smash burger restaurants serve a double (two patties) as the standard order, which uses about 5–6 ounces of beef total.
Why does 80/20 ground beef matter so much for smash burgers?
The fat-to-lean ratio is critical. When an 80/20 patty is smashed onto a screaming-hot surface, the fat renders instantly and creates deep caramelization and those signature crispy edges through the Maillard reaction. Leaner beef (90/10 or 93/7) lacks the fat needed for this crust and results in a dry, pale, less flavorful patty.
What is special sauce made of for smash burgers?
Most smash burger special sauces are a variation of fry sauce: roughly 3 parts mayonnaise, 1 part ketchup or yellow mustard, diced dill pickles or sweet relish, a splash of pickle brine, garlic powder, and a pinch of smoked paprika. The ingredients are pantry staples, making the sauce cost roughly $1.50–$2.50 for a batch that covers 8–10 burgers.
How does the homemade cost compare to Smashburger vs. Five Guys?
A homemade double smash burger typically costs $2.50–$4.00 per burger in ingredients. A comparable double at Smashburger averages $9–$10, and at Five Guys a double burger runs $12–$14 before tax. That means homemade saves you roughly $6–$10 per burger compared to these chains.
Can I make smash burgers without a flat-top grill?
Yes. A heavy cast-iron skillet or carbon steel pan on your stovetop is the best home substitute for a flat-top griddle. Preheat it on high heat for at least 3–5 minutes before cooking. A pre-seasoned cast-iron pan costs $25–$40 and lasts a lifetime, paying for itself in the first smash burger night.

How Much Does a Homemade Smash Burger Actually Cost?

Smash burgers have taken over backyards, food trucks, and gourmet restaurants alike. A homemade double smash burger — two 3-ounce patties, two slices of American cheese, a toasted potato roll, special sauce, dill pickles, and diced onion — typically costs between $2.50 and $4.00 per burger. Compare that to $9–$13 at Smashburger or Five Guys, or $15–$20+ at a gourmet burger bar, and you are looking at savings of 60–85% per serving.

The Key Ingredients and What They Cost

80/20 ground beef is non-negotiable for a real smash burger. The 20% fat content is what creates those crispy, caramelized edges. At most grocery stores, 80/20 ground beef runs $5–$8 per pound. Each smash patty is roughly 3 ounces (pre-cook), so a single pound yields about 5–6 patties. For a double smash, you need two patties.

Potato rolls are the classic smash burger bun. A standard 8-pack costs $3–$5, putting the per-bun cost at $0.38–$0.63. Martin's Potato Rolls are the gold standard among enthusiasts.

American cheese — specifically individually wrapped deli-style slices — melts into a glossy, creamy blanket that is the signature of the style. Two slices per double burger at $0.37–$0.62 per pair.

Special sauce, dill pickles, and diced onion add roughly $0.30–$0.60 total per burger when drawn from standard grocery quantities.

Batch Cooking Savings

Eight double smash burgers at home might cost $20–$32 in total ingredients. That same order at Five Guys for four people would run $50–$60 before drinks, tax, and tip. Hosting a smash burger night at home for eight people saves a realistic $30–$60 compared to a restaurant outing.
