This is a beef burger built around Spanish pantry staples — smoked paprika, green olives, and capers mixed straight into the chuck, with a from-scratch ketchup and a quick aioli-style mayo on top. The honest reason to make it is that every component is homemade, so you control the flavor at every layer. It takes four hours start to finish, but most of that is hands-off rise time for the buns.
What makes this version work
Two things matter most here. First, mincing the olives and capers finely before mixing them into the chuck keeps the patties from falling apart on the grill — large chunks create weak spots. Second, the bun dough gets a full two-hour rise twice over, and that patience is what gives you a crumb sturdy enough to hold a juicy patty without going soggy. Rushing either rise produces a bun that collapses under the weight of the fillings. Everything else in this recipe is flexible; these two steps are not.
Shopping notes
- Jerez vinegar (sherry vinegar): sold in most well-stocked grocery stores and any Spanish or Latin market. If you can’t find it, a good red wine vinegar works, but use slightly less — it’s sharper.
- Spanish smoked paprika (pimentón): look for tins labeled pimentón de la Vera picante for the spicy variety called for here. Generic smoked paprika is milder and less complex; it’ll work but the flavor won’t be as pronounced.
- Green olives with stones removed: buy pitted olives to save yourself the work. Manzanilla or Gordal olives are the right style — avoid anything pre-marinated in herbs, which will muddy the flavor.
- Ground chuck: aim for 80/20 fat ratio. Leaner grinds dry out fast on a hot grill, especially with the salt from the capers and olives already in the mix.
Troubleshooting
- Patties shrink into thick pucks on the grill: press a shallow dimple into the center of each raw patty with your thumb before grilling. The patty will still contract, but it stays flat instead of doming up.
- Ketchup stays thin after an hour of simmering: your tomatoes had a high water content. Remove the lid and increase the heat slightly to drive off more moisture — check every 10 minutes and stir so the bottom doesn’t scorch.
- Buns brown on the outside but feel doughy inside: your oven ran hot and the crust set before the interior cooked through. Use an oven thermometer to verify temperature, and tent the buns loosely with foil for the last 5 minutes if the tops are darkening too fast.
- Olives and capers make the patties too salty: rinse the capers under cold water and pat them dry before mincing. Olives packed in brine should also get a quick rinse. Hold off on adding any extra salt to the mix until after you taste a small cooked piece.
- Mayo aioli tastes raw and harsh: the garlic needs the full hour in the fridge to mellow. If you’re short on time, microwave the minced garlic with a drop of olive oil for 15 seconds before mixing — it takes the raw edge off quickly.
Leftovers and meal prep
Cooked patties keep in the fridge for up to three days in an airtight container; reheat them in a covered skillet over medium-low with a splash of water to keep them from drying out — about 3 minutes per side. Raw shaped patties can be frozen for up to two months: stack them with parchment between each one and seal tightly. The ketchup keeps refrigerated for up to a week and actually improves on day two once the flavors settle, so making it the day before a cookout is a smart move. The aioli-style mayo should be used within three days. Baked buns freeze well for up to a month; wrap each one individually and thaw at room temperature for about an hour before serving.

Instructions
How To Make Homemade Spanish Ketchup:
- Soften minced garlic and chili in olive oil in a saucepan.
- Slice tomatoes in 4 slices and add them to the saucepan, too. Let the tomatoes soften a bit so that juice is extracted.
- Stir the mixture every once in a while. When tomatoes are soft, and juices are boiling, add a little bit of honey to cut the bitterness of tomatoes, a pinch of salt, pepper and smoked paprika and a splash of vinegar to taste. Too not over a season because the ketchup is reduced by half. Add tomato paste, which brings flavor and turns color from yellowish to more red. Let the mixture simmer for about 1-1.5 hours until the structure is right. Add salt, pepper, smoked paprika, honey and vinegar, if needed. Stir well and let it cool before serving.
How To Make Hamburger Buns For 4 Servings:
- Combine warm water, milk, yeast and sugar. Let it rest for 5 minutes. Break 1 egg in a glass and whisk a little. Put flour in a bowl and stir the salt and soft butter in. Then add the water/milk mixture and the whisked egg and knead to a dough.
- Transfer the dough to a lightly floured surface and knead for about 8-10 minutes until the dough becomes smooth and elastic. The dough will be sticky, so you may need to add a little flour to knead easier.
- Rise for 2 hours. Time seems long, but it is worth it.
- Roll the flattened balls and rise under a towel for another 2 hours.
- After 4 hours of waiting, brush with egg and add sesame seeds. Bake at 200 °C (400 ºF) for 10-15 minutes. Let the buns rest for at least 10 minutes before cutting them.
How To Make Spanish Mayonnaise:
- Mince the garlic and mix well with mayonnaise and smoked paprika. Voilá, you are done! Let the mixture rest in the fridge for at least an hour.
How To Make Spanish Hamburgers For 4 Servings:
- Mince olives and capers and mix well with ground chuck, smoked paprika, salt and ground black pepper. Shape the hamburgers and grill them for about 2 minutes per side if you want them medium.
- Cut the buns in half and coat the top side with the mayo and the bottom side with the ketchup. Put onion/paprika mix on the bottom, place the hamburger on top of that and finish with cheese of your choice. We used brie which works very well with this hamburger.

Your questions, answered
Can I make the bun dough the night before?
Yes — after the first knead, cover the dough tightly and let it rise slowly in the fridge overnight instead of on the counter. Take it out the next morning, shape the buns, and do the second two-hour rise at room temperature before baking.
How do I know when the patties are done without cutting into them?
Use an instant-read thermometer and pull the patties at 160°F (71°C) internal temperature — that’s the safe target for ground beef. Two minutes per side is a starting point, but grill heat varies enough that a thermometer is the only reliable check.
Can I double or triple this recipe for a larger group?
The patty and ketchup components scale up cleanly — just multiply straight across. For the buns, it’s more practical to make two separate batches of dough rather than one giant batch, since very large doughs are harder to knead evenly and may not rise as consistently.
What cheese works best if I can’t find brie?
Manchego is the most natural fit given the Spanish flavor profile — skip the egg in the mix — it makes the patty mushy. A young Manchego melts reasonably well; aged Manchego is drier but still good. Provolone is a reliable backup if neither is available.
