Thai Basil Beef Burgers with Crispy Fried Egg
Juicy pan-seared beef patties packed with Thai basil, garlic, fresh chilies and fish sauce, topped with a lacy crisp-edged fried egg, cool cucumber and a lime-sriracha mayo. Inspired by the flavors of pad kra pao, in burger form.
Steps
Before you start
- Use 80/20 ground beef straight from the fridge. Cold fat keeps the patties tender and juicy.
- Thai basil has a licorice-like, peppery flavor that regular Italian basil can't match. Look for it at Asian markets (see substitutions if you can't find it).
- Thai bird chilies are very hot. Wear gloves or wash your hands well after cutting them, and remove the seeds if you want less heat.
- Plan on 60 minutes total, including a 15-minute chill for the patties.
- Turn on your stove vent or open a window. Searing with fish sauce makes a strong aroma.
Make the mayo
- In a small bowl, stir together the mayonnaise, sriracha and lime juice until smooth and evenly pink-orange.
- Cover and refrigerate.
- Slice the cucumber into thin rounds and set aside along with the 16 whole Thai basil leaves for topping.

Ready when: Sauce is smooth with no white streaks of mayo.
Tip: Taste it. Add a few more drops of lime juice if you like it tangier.
Prep the aromatics
- Finely chop the ½ cup (20 g) packed basil, mince the garlic, and mince the chilies.
- Everything should be in pieces smaller than a grain of rice so no one bites into a big chunk of chili.

Ready when: Basil, garlic and chilies are finely minced.
Tip: Wash your hands and knife with soap after cutting the chilies, before touching your face.
Mix the patties
- In a large bowl, combine the cold beef with the basil, garlic, chilies, fish sauce, brown sugar and white pepper.
- Use your fingertips to toss and fold just until the seasonings are evenly distributed, about 20 seconds.
- Don't knead or squeeze.

Ready when: Seasonings are evenly visible with no pockets of plain beef, and the meat still looks loose, not pasty.
Tip: Overworking the meat makes dense, rubbery burgers.
Shape and chill
- Divide the mixture into 4 equal portions of about 6 oz (170 g) each.
- Gently shape each into a patty about 4 inches (10 cm) wide and ¾ inch (2 cm) thick, then press a shallow thumb-sized dimple into the center of each.
- Place on a parchment-lined plate or baking sheet, cover loosely, and refrigerate for 15 minutes.

Ready when: Patties feel firm and cold to the touch.
Tip: The dimple stops the centers from puffing into domes as the burgers cook.
Sear the pattiesOven 160°F / 70°C
- Heat the 12-inch skillet over medium-high heat for 2 minutes.
- Add 1 tbsp (15 ml) oil and swirl until it shimmers.
- Add the patties, leaving space between them, and cook undisturbed for 4 minutes until a deep brown crust forms.
- Flip once and cook 3 to 4 minutes more, until an instant-read thermometer in the center reads 160°F (71°C).

Ready when: Both sides are deeply browned and the center reads 160°F (71°C).
Tip: Don't press down on the patties with the spatula. That squeezes out the juices.
Rest and toast buns
- Move the patties to a clean plate and let them rest for 3 minutes.
- Meanwhile, pour off all but about 1 tsp of fat from the skillet, reduce the heat to medium, and place the buns cut-side down.
- Toast for 1 to 2 minutes, until golden brown, then set them aside.

Ready when: Cut sides of the buns are golden brown and lightly crisp.
Tip: Watch closely. Brioche contains sugar and goes from golden to burnt quickly.
Fry the eggs
- Wipe out the skillet if there are burnt bits.
- Heat 2 tbsp (30 ml) oil over medium-high heat until it shimmers and a drop of egg white sizzles right away.
- Slide in the eggs from their cups, spacing them apart.
- Cook 2 to 3 minutes, spooning a little hot oil over the whites, until the whites are set and have crisp, lacy brown edges and the yolks are still glossy.
- Transfer to a paper-towel-lined plate.

Ready when: Whites are fully opaque with crisp, bubbly brown edges; yolks are still soft. For a firm yolk, cook another 1 to 2 minutes.
Tip: Cracking eggs into cups first lets them slide into the hot oil together without breaking the yolks.
Assemble and serve
- Spread the lime-sriracha mayo on both halves of each toasted bun.
- Layer the bottom bun with cucumber slices, a patty, and 4 whole Thai basil leaves.
- Top with a fried egg, then the top bun.
- Serve right away while the egg is still hot.

Ready when: Burgers are stacked with the egg on top and the yolk still glossy.
Tip: Press the top bun down gently. When you bite in, the yolk should run into the patty like a sauce.
Good to know
Tips
- Keep the beef cold and handle it as little as possible for a tender burger.
- Use a hot pan and don't move the patties for the first 4 minutes to build a good crust.
- Fish sauce brands vary in saltiness. If yours is very salty, use 2 tsp instead of 1 tbsp.
- Add quick-pickled red onions or shredded carrots for extra crunch and acidity.
Make ahead
"Mix and shape the patties up to 1 day ahead; cover and refrigerate on a parchment-lined plate. The mayo keeps up to 3 days in the fridge. Slice the cucumber and cook the eggs just before serving."
Storage & reheating
Best eaten right away. Store cooked patties (without bun, egg or toppings) in an airtight container in the fridge up to 3 days; reheat in a covered skillet over medium-low heat for 3 to 4 minutes until steaming hot, to 165°F (74°C). Raw shaped patties freeze well for up to 3 months, separated by parchment; thaw overnight in the fridge before cooking. Fried eggs don't store well, so cook fresh.
Substitutions
- Thai basil leaves → Half Italian basil and half fresh mint, with a pinch of ground star anise. Gives a similar herbal, slightly sweet flavor if Thai basil isn't available.
- Thai bird chilies → 1 red serrano or 1 small jalapeño. Milder heat; mince it just as finely.
- fish sauce → Soy sauce (1 tbsp / 15 ml). Less funky and slightly less salty; gives a milder umami taste.
- 80/20 ground beef → Ground pork or ground dark-meat chicken or turkey. Cook chicken or turkey patties to 165°F (74°C) and pork to 160°F (71°C).
