A quick stroll up Broadway from the eponymous Southie T stop, Lincoln Tavern & Restaurant is a mainstay covered in beautiful, exposed brick. A prime spot for watching the game with a big group, it’s best known for wood-fired pizza, pub faves like Spicy Wings served late, and everyday brunch creations. But Lincoln also takes its job seriously as a reliable neighborhood tavern, evinced by the menu-favorite rich crock of French Onion Soup, deeply caramelized and topped with garlic croutons and dripping gruyère cheese.

Nestled on the corner of Massachusetts and Commonwealth avenues, Deuxave is a high-end go-to for a French fix and so many craveable moments, such as supremely roasted chicken and a hearty bowl of Bolognaise.

The name alludes to the care it takes chef Chris Coombs’ team to develop the flavor of the slow-cooked beef broth, which is enhanced with a bone marrow crouton and comte cheese.
Mosey through Beacon Hill over to Ma Maison to find an intimate dining atmosphere and dishes that have stood the test of time. Think luscious Country Pȃté, buttery Escargots imported from Burgundy, succulent Beef Bourguignon, and truly what we’re here for: fortifying French Onion Soup. With a white-tablecloth dining room and a robust wine list, this small French restaurant is romantic, but Ma Maison is also fit for a casual dinner, lunch, or weekend brunch.
Somerville neighborhood restaurant Juliet is inspired by coastal France (with an Italian accent). That means it understands simplicity and the importance of executing refined dishes. Instead of an overflowing bowl dripping in cheese, Juliet’s French Onion Soup nestles a gruyére-covered baguette right in for a nice soak.

The French Onion Soup made the move: it’s available on the nightly dinner menu as well as during Friday lunch.
The anchor of the Cambridge Crossing trio of restaurants by chef Will Gilson, The Lexington is located in an airy, window-filled dining room with dynamite views. There’s French Onion coziness on the menu, but it’s not your conventional soup—nor really a soup at all. French Onion Grilled Cheese emulates the classic in sandwich form, filled with caramelized onions and covered in melted gruyére both inside and out. Served with a side of mushroom jus, this clever riff hits the spot with warmth and a vegetarian umami blast.
Grill 23 & Bar
The French Onion Soup at Grill 23 & Bar is simply mouthwatering. The steakhouse app is incredibly rich—simultaneously very sweet and super salty—topped with molton gruyére and house-baked focaccia croutons. It’s picture-perfect served in an adorable cast-iron crock, alongside excellently icy Martinis or a pick from the extensive, highly lauded wine list. Ask about a tannic match for the decadent soup, or heck—go for grower champagne.
