This burger mixes lime juice, fresh cilantro, diced tomato, and red onion directly into the beef, so the patty itself carries the bright, tangy flavors of a ceviche rather than just wearing them as toppings. The avocado-lime mayo brings enough richness to hold the whole thing together. It takes about 50 minutes start to finish and makes a genuinely interesting weeknight dinner without requiring any hard-to-find ingredients.
About the ingredients
- Ground beef: Grass-fed is called for, but any 80/20 ground beef works well here. The fat content matters more than the label — leaner blends tend to dry out, especially with the added moisture from lime juice and tomatoes.
- Lime juice: Use fresh-squeezed. Bottled lime juice is noticeably more bitter and will throw off the flavor of both the patty and the mayo.
- Avocado: It needs to be ripe — press the skin gently and it should give slightly. An underripe avocado won’t mash smoothly and the mayo will be lumpy and bland.
- Cilantro: The recipe notes that parsley is a valid swap if you’re sensitive to cilantro. Flat-leaf parsley is the better choice over curly — it has more flavor.
- Burger buns: A sturdy bun matters here. The patty has extra moisture from the tomatoes and lime, so a soft grocery-store bun can go soggy fast. Brioche or a potato roll holds up better.
Why this recipe works
Mixing the aromatics — onion, cilantro, tomato, lime — directly into the beef does two things at once. It seasons the meat all the way through, not just on the surface, so every bite has flavor. And the lime juice starts to break down the outer proteins slightly during the short marinating window, which helps the patty stay tender after it hits the heat. The key is keeping that marinating time short — the recipe has you prep the mayo while the meat sits, which is roughly the right amount of time. Let it go much longer and the texture of the beef starts to get pasty.
Mistakes to avoid
- Overworking the mix: Stir the beef and aromatics together just until combined. Aggressive mixing compacts the proteins and produces a dense, tight patty — stop as soon as you don’t see dry pockets.
- Skipping the chill on the mayo: The avocado-lime mayo needs at least 10 minutes in the fridge before serving. Room-temperature mayo on a hot patty turns runny and slides off immediately.
- Making the patties too thin: The added moisture from tomatoes and lime means these patties shrink and flatten more than a plain beef patty. Keep them at the full 2 cm (about ¾ inch) thick, or slightly thicker, before cooking.
- Undercooking: Ground beef must reach an internal temperature of 160°F (71°C). Use an instant-read thermometer — the aromatics in the mix make it harder to judge doneness by color alone, since the patties can look done on the outside while still being undercooked inside.
- Skipping the bun toast: Skip the egg in the mix — it makes the patty mushy — but don’t skip toasting the bun. A toasted surface creates a barrier that slows down the moisture from the patty and the mayo.
Storage and reheating
Cooked patties keep in an airtight container in the fridge for up to 3 days. Store the avocado-lime mayo separately — avocado oxidizes quickly, so press a piece of plastic wrap directly onto the surface before sealing, and use it within 2 days. To reheat patties, a skillet over medium heat for 2 to 3 minutes per side works better than a microwave, which tends to make the tomato pieces watery and steams the meat unevenly. Raw patties can be frozen before cooking: form them, separate with parchment, and freeze for up to 2 months. Thaw overnight in the fridge before grilling.
Ecuadorian Ceviche-Inspired Burger
Ingredients
Burger Components
- 500 grams ground beef preferably grass-fed
- 1 medium red onion finely diced
- 1 cup cilantro fresh, chopped
- 2 tablespoons lime juice freshly squeezed
- 2 medium ripe tomatoes diced
- 1 teaspoon sea salt
- 4 pieces burger buns toasted
Avocado-Lime Mayo
- 1 medium avocado ripe
- ½ cup mayonnaise of preference
- 2 tablespoons lime juice freshly squeezed
Instructions
- Begin by finely dicing the red onion and chopping the cilantro. In a large mixing bowl, combine these with the ground beef, tomatoes, and sea salt. Mix gently to incorporate and then add the lime juice, allowing the mixture to marinate while you prepare the avocado-lime mayo.
- For the avocado-lime mayo, mash the avocado until smooth. Stir in the mayonnaise and lime juice. Whisk until creamy and set aside in the refrigerator to chill.
- Heat a grill or a skillet to medium-high heat (around 190°C/375°F). Form the beef mixture into four equal patties, about 2 cm thick. Cook on the grill for about 10 minutes, flipping halfway through, until the outside is browned and the inside reaches your desired doneness.
- Meanwhile, toast the burger buns. Once the patties are ready, generously spread the avocado-lime mayo on both sides of each bun.
- Assemble the burgers by placing the patty between the prepared buns. For additional flavor and texture, garnish with extra cilantro or a handful of arugula.

FAQ
Can I make the patties ahead of time?
Yes — form the patties and refrigerate them (uncooked) for up to 24 hours before grilling. Beyond that, the lime juice continues working on the beef and the texture starts to soften too much.
How do I keep the patties from falling apart on the grill?
Make sure the grill grates are clean and well-oiled before the patties go on, and don’t move them until they release naturally — usually 4 to 5 minutes. The diced tomato adds moisture that can make these patties a little more fragile than a plain beef patty, so handle them minimally.
What internal temperature should I cook these to?
Ground beef needs to reach 160°F (71°C) internal temperature. An instant-read thermometer is the most reliable way to check — the aromatics mixed into the patty can make the color misleading.
Can I cook these in a skillet instead of on a grill?
Yes, a cast-iron or heavy stainless skillet over medium-high heat works well. You won’t get grill marks, but you’ll get a solid sear — make sure the pan is hot before the patties go in so they don’t steam.
My avocado-lime mayo turned brown quickly — what went wrong?
Avocado oxidizes fast once mashed, even with lime juice in the mix. Press plastic wrap directly against the surface of the mayo (not just over the bowl) to limit air contact, and make it as close to serving time as possible.
