Here’s the quick hit version:

- Shape and chill – Form into patties slightly larger than your buns (they’ll shrink as they cook). A short fridge rest helps them hold shape.

This method is fast, forgiving, and almost impossible to mess up the soup mix does most of the heavy lifting while you take all the credit.
The Best Meat and Cheese Pairings for French Onion Soup Burgers
A burger is only as good as the meat and cheese you put on it, and with French onion soup burgers, the right pairing turns “good” into “can’t stop eating this.”
Best meats for that rich, oniony flavor:
- Ground beef (80/20 blend) – The extra fat keeps patties juicy and amplifies the soup mix’s savory punch.
- Ground turkey or chicken – Lighter, but still soaks up the onion flavor beautifully. Add a touch of olive oil for moisture.
- Ground lamb – Bold, slightly gamey, and amazing with caramelized onions.
Cheeses that make it unforgettable:
- Gruyère – The classic choice; nutty, melty, and straight out of the French onion soup playbook.
- Swiss – Smooth and mild with just enough sharpness to cut through the richness.
- Provolone – Melts like a dream and adds a subtle smoky note.

Cooking Instructions for Perfect French Onion Soup Burgers
Making burgers with French onion soup is all about building layers of flavor — and that starts before the patties even hit the heat.
1. Caramelize the onions
In a skillet over medium-low heat, melt butter with a drizzle of olive oil. Add sliced onions and cook slowly, stirring often, until they turn deep golden brown (about 25–30 minutes). For extra richness, splash in a bit of beef broth toward the end. See our Sautéed Zucchini Recipe for more tips on coaxing flavor out of vegetables.
2. Prep the patties
In a large bowl, gently mix ground beef with dry French onion soup mix. Shape into patties slightly wider than your buns — they’ll shrink as they cook.
3. Cook the burgers
Heat a grill or skillet to medium-high. Cook patties 3–4 minutes per side for medium doneness, or to your preferred temperature. In the last minute, top with cheese and cover to melt.
4. Assemble and serve
Place patties on toasted buns, add caramelized onions, and finish with your favorite condiments. Serve immediately while everything’s hot and melty.
What to Serve with French Onion Soup Burgers
A burger this good deserves sides that can keep up. Whether you’re planning a weeknight dinner or a weekend feast, the right accompaniments make the whole meal shine.
Classic sides that never fail:

- Roasted vegetables – Sweet, slightly charred, and a perfect contrast to the savory burger. Learn the technique with our Sautéed Zucchini Recipe.

Soup on the side:
If you really want to lean into the French onion theme, serve a small cup of soup alongside the burger for dipping. The melted cheese and broth-soaked bread make an indulgent side that mirrors the flavors in your patty.
Pairing is about balance, rich with light, crunchy with soft, so every bite feels fresh and exciting.

Tips and Tricks for Juicy, Flavor-Packed French Onion Soup Burgers

Pro flavor moves:

- Soup mix mayo – Stir a teaspoon of dry French onion soup mix into mayonnaise for a quick burger spread that’s packed with umami.
- Cheese layering – Melt cheese directly on the patty, then add another thin slice after assembly for extra indulgence.
Creative twists:
- Turkey sliders – Mini patties for parties; get more inspiration from our Low FODMAP Chicken Stir Fry for seasoning ideas.
- Mushroom-onion patties – For a vegetarian option, swap the meat for a mix of mushrooms and onions, then bind with breadcrumbs and egg. See our FODMAP Banana Pancakes for a fun take on alternative binding methods.
