Method

  1. 1Put the ground beef in a bowl, season it liberally with Royal Nova BBQ Spice and mix it through.Mixing the seasoning into the meat, rather than only dusting the top, seasons the whole layer — and once it is spread this thin there is no inside to worry about. Mix only until the spice is evenly distributed. Overworked ground beef turns dense and springy.
  2. 2Spread a thin, even layer of beef over each Dempster's tortilla, working from the centre out to the edge.Thin is the whole point: the beef has to cook through in the time it takes the tortilla to crisp. Take it right to the rim — in the video it could have been spread a little further. Ground beef shrinks and pulls in from the edges as it cooks, and a thick centre lags behind the tortilla.
  3. 3Oil the hot griddle with grapeseed oil and lay the tortillas beef-side down, pressing each one flat.Grapeseed oil has a high smoke point, so it will not burn at searing heat. Pressing puts the whole surface of the beef in contact with the steel, which is where the crust comes from. The griddle was on medium in the video and the crust came slowly, so start a little hotter. A large frying pan does the same job if you do not have a griddle.
  4. 4Leave them beef-side down for 4–5 minutes, until a real crust has formed, before flipping.This is where the cook in the video went off the rails: the first flip came after only 3–4 minutes, before the crust had built, and 5–6 minutes would have been better at that heat. The beef should be deep brown at the edges before you turn it. Patience here saves extra flips later.
  5. 5Flip onto the tortilla side and cook for about 4 minutes, until the tortilla is crisp.The fat rendering out of the beef fries the tortilla from underneath, which is what turns a soft tortilla into a tostada. If a tortilla puffs up with trapped steam, stab it with the corner of the spatula and it will deflate. Flip carefully — hot beef fat can flick off the griddle, and grease is flammable.
  6. 6Flip back onto the beef side for a final minute or two of sear.This last flip is what rescued the cook in the video. By then the tortilla has soaked up some of the fat and fried, and the extra time on the beef side builds the browning and char the first pass missed. Take them off when the beef edges are dark and crisp.
  7. 7Mix the burger sauce: two parts mayonnaise, two parts ketchup and one part mustard.It is the classic burger sauce balance — mayonnaise for richness, ketchup for sweetness, mustard for sharpness. Keep the ratio and scale it to the size of the batch. Mix it smooth so every spoonful has all three.
  8. 8Spread the sauce over the beef and top with shredded lettuce, red onion and pickled hot peppers.Dress them like a burger, and do it right before eating — sauce and wet lettuce soften a crisp tortilla within minutes. The pickled peppers bring acid and heat that cut through the beef fat. There was no cheese on these, though the video suggests it as an easy upgrade.

What each ingredient is doing

Ground beef
The fat that renders out is what fries the tortilla, so regular or medium ground beef works better than extra-lean, which leaves the tortilla dry and the beef crumbly. Ground pork or a pork and beef mix also work.
Dempster's tortillas
The base and the crunch. Any soft tortilla crisps in the rendered beef fat; smaller ones are easier to flip. Corn tortillas crisp harder but are smaller and crack more easily when turned.
Royal Nova BBQ Spice
Mixed into the beef so the whole thin layer is seasoned. Any savoury burger or steak seasoning can stand in, or simply salt, pepper and garlic powder.
Grapeseed oil
High smoke point and neutral flavour, which is all a griddle oil needs. Avocado or canola oil work the same way; butter burns at this heat.
Burger sauce
Two parts mayonnaise, two parts ketchup, one part mustard — rich, sweet and sharp. Stir in chopped dill pickle or relish if you want it closer to a burger-joint special sauce.
Pickled hot peppers
Acid and heat against the fatty beef. Pickled jalapeños, banana peppers or dill pickle slices all do a similar job.
Lettuce and red onion
Cold crunch and bite against the hot beef. Shred the lettuce fine so it sits flat on the tostada instead of sliding off.

Pitmaster tips

  • Spread the beef thin and all the way to the edge. It shrinks as it cooks, and a thick centre lags behind the tortilla.
  • Mix the seasoning into the beef rather than only sprinkling the top, so the whole layer is seasoned.
  • Run the griddle hotter than medium. The medium setting in the video built the crust too slowly.
  • Press each tostada down when it hits the griddle so the whole beef surface is in contact with the steel.
  • Do not flip until the beef edges are deep brown. Flipping too early was the one real mistake in the video.
  • Stab puffed tortillas with the corner of the spatula to let the steam out; they flatten straight away.
  • Watch the grease. Beef fat on a hot griddle spits and can flick when you flip, and it is flammable.
  • A final flip back onto the beef side is an easy fix for a weak crust — it is what saved the cook in the video.
  • Dress them right before eating. Sauce and lettuce soften a crisp tortilla within minutes.
  • Keep the sauce at 2:2:1 — mayonnaise, ketchup, mustard — and scale it to the batch.

If it goes wrong

The beef has no crust
The griddle was too cool or the first flip came too early. Turn the heat up past medium, press the beef down and give it the full 4–5 minutes. If it is already flipped, turn it back onto the beef side for another minute or two.
The tortilla puffed up like a balloon
Steam is trapped between the layers of the tortilla. Poke it with the corner of the spatula and press it flat; it crisps normally after that.
The tortilla is soggy
It did not get long enough on the tortilla side, or it was dressed too early. Give it the full time frying in the rendered fat, and add sauce and lettuce only when serving.
The middle is thick and underdone
The beef was piled in the centre. Spread it evenly right to the edge before it goes on the griddle.
The tortilla edges burnt
Bare tortilla around the rim cooks much faster than the beef-covered centre. Take the beef right to the edge and drop the heat slightly for the tortilla side.
The grease flared up
Too much beef fat pooled on the griddle. Scrape the excess toward the grease trap between batches and keep the spatula low when flipping so fat does not flick.

Ways to change it up

Cheeseburger tostadas
After the final sear, turn them tortilla side down, lay a slice of cheese on the beef and cover for 30 seconds or so to melt. The video suggests cheese as the obvious upgrade.
In a frying pan
Works the same on the stove, one or two at a time. Use a heavy pan and get it properly hot before the first one goes in.
Special sauce
Add finely chopped dill pickle or relish and a pinch of onion powder to the burger sauce.
Taco-style
Swap the burger toppings for salsa, sour cream, shredded cheese and cilantro.
Ground pork
Use ground pork or a pork and beef mix. Cook it to 160°F; a thin layer gets there quickly.

What to serve it with

  • Dressed like a burger with burger sauce, shredded lettuce, red onion and pickled hot peppers, as in the video.
  • Fries or potato wedges.
  • Coleslaw or a crisp green salad.
  • Dill pickle spears on the side.
  • A cold beer.

Storage & reheating

Best eaten straight off the griddle. Leftover cooked tostadas keep 3–4 days refrigerated if stored undressed, with the sauce and toppings kept separate.

Reheat on a hot griddle or in a frying pan, beef side down first and then tortilla side, to bring the crunch back; a few minutes in a 400°F oven or air fryer also works. The microwave turns the tortilla limp and chewy.

Cooked tostadas do not freeze well, because the tortilla goes soft as it thaws. Freeze the raw ground beef instead, for up to 3–4 months, and keep leftover burger sauce in the fridge for up to a week.

FAQ

Can I make burger tostadas without a griddle?

Yes. A large frying pan or cast iron skillet on the stove does the same job, as the video points out. Cook one or two at a time so the pan stays hot, and use a high smoke point oil.

Why is my tortilla puffing up on the griddle?

Heat turns moisture in the tortilla to steam, which separates the layers and balloons them. It is harmless. Stab it with the corner of the spatula, press it flat and it will crisp normally.

Is a thin layer of ground beef cooked through?

Easily. Ground beef is safe at 160°F, and a layer this thin passes that well before the crust is finished. The time on the griddle is for browning and crisping, not for cooking it through.

How do I get a better crust on the beef?

A hotter griddle, a firm press when it goes down and patience before the first flip. The video ran medium heat and flipped at 3–4 minutes, which was too soon; a final flip back onto the beef side for a minute or two fixed it.

What is in the burger sauce?

Two parts mayonnaise, two parts ketchup and one part mustard, mixed smooth. It is the base of most burger sauces; add chopped pickle or relish if you want it closer to a special sauce.

Can I add cheese to burger tostadas?

Yes. There was none in the video, but it is suggested as an easy upgrade. After the final sear, turn the tostadas tortilla side down, lay a slice on the beef and cover briefly to melt it.

Know your cook

More information, cause recipe back stories are stupid

No 500-word life story — just the good-to-know stuff on what’s actually in this cook. Here’s the rundown on every real ingredient, health and nutrition wise.

Beef
Beef is a complete protein and one of the best food sources of highly absorbable heme iron, zinc, and vitamin B12 — key for energy, immunity, and healthy blood. Fattier BBQ cuts are calorie-dense, so lean trimming and sensible portions keep it balanced.
Onion
Onions are low-calorie aromatics rich in fibre, vitamin C, and antioxidants such as quercetin. They add depth and gentle sweetness without much fat or salt.
