The fillings and bread vary, but the effect is often the same. A great breakfast sandwich provides a comforting base for the day and contributes plenty of calories to fuel productivity. Results vary depending on whether you’re a lumberjack or software engineer. Regardless, learn about 10 Top Los Angeles Breakfast Sandwiches that span the city.

Establishments appear in alphabetical order instead of in order of preference.

1. Baco Mercat: Chef Josef Centeno built the restaurant around his bäco, a folded-over flatbread sandwich. Yes, they offer a breakfast bäco during Saturday’s Hair of the Dog Brunch that touts chorizo and egg, but I prefer the lunchtime variation with a breakfast feel, the Toron ($12). A supple flatbread with a blistered base cradles juicy pulled oxtail, which forms a patty. Chef Centeno pairs them with a crispy hash brown “tater” patty and balances fillings with sprouts, arugula and mesclun mix, spicy orange aioli, pickle and cheddar.

2. BLD< [CLOSED]

At Neal and Amy Fraser’s three-square establishment in Mid-City, they feature a Fried Egg Sandwich ($13). Toasted sourdough sandwiches smoky, thick-cut Nueske bacon, Gruyère cheese, a judicious amount of aioli and a runny fried egg. Choice of potatoes includes my pick, olive oil roasted fingerlings.

3. Clementine: At chef Annie Miler’s Century City café, Clementine Breakfast Sandwich ($7.95) comes on a flaky, oversized biscuit with a runny poached egg that’s molded into a disc, melted cheddar and savory Tennessee country ham.

4. Cuscatleca Bakery: This Echo Park bakery, named for a city in El Salvador, does sell an American-style Breakfast Sandwich, but I’d suggest the Torta de Frijoles ($3.50) with soft bollilo-like pan Frances, refried beans, firm slab of savory queso fresco, creamy avocado and spicy jalapeno with a choice of banana chips or balsamic-doused side salad. Add “scrambled eggs” (a folded over omelet) for $1, and homefries for a buck more.

5. Egg Slut: Truck-meister Alvin Cailan has gained a loyal following in West Hollywood and the downtown Arts District thanks to egg-centric offerings like the Fairfax ($6) soft scrambled eggs, Tillamook cheddar, chives, caramelized onions and Sriracha mayo on buttery brioche bun.
