- Ground Beef (80/20): The ideal fat ratio for juicy burgers that sizzle and crisp just right on a hot skillet.
- Small Onion: Finely grated or very thinly sliced, onions melt into the patty, adding sweetness and that signature classic smash burger taste.
- Garlic Cloves: Minced fresh garlic brings a deep, savory kick no jarred version can match.

- Kosher Salt: Enhances all the meaty flavors without overpowering them; a must for seasoning beef.
- Black Pepper: Freshly cracked black pepper ensures a pleasant, peppery finish in every bite.
- Cheddar or American Cheese: Melts quickly and delivers that signature creamy topping, so don’t be shy with it!
- Burger Buns: Opt for soft, sturdy buns that can hold up to the juicy patties and toppings.

- Optional Toppings: Pickles, lettuce, tomato, mayo, and mustard all stack on fresh flavor, so choose your favorites.
How to Make Garlicky Onion Smash Burger
Step 1: Prep Your Skillet and Gather Ingredients
Begin by preheating a cast iron skillet or griddle over medium-high heat until it’s rip-roaring hot—you want that satisfying sizzle. While it heats up, get all your ingredients ready and within arm’s reach, so nothing slows you down once those burgers hit the heat.
Step 2: Mix the Beef with Flavor Boosters
In a medium bowl, gently combine your ground beef with the minced garlic, Worcestershire sauce, kosher salt, and black pepper. Don’t overwork the meat—just fold the seasonings in until barely combined. Divvy the mixture into four equal balls, which helps keep the burger super juicy and tender.
Step 3: Toast the Buns
Before the excitement of the smash, quickly butter or oil your buns and toast them cut-side down in the hot skillet until golden and crisp. This step is easy to overlook, but trust me—it’s the secret to a textural contrast that makes the Garlicky Onion Smash Burger irresistible.
Step 4: Smash and Sauté
Place a beef ball onto the screaming hot skillet, immediately top it with a small heap of finely sliced or grated onions, then smash it flat with a sturdy spatula or burger press. Press hard! The thinner you go, the crispier those gorgeous edges will be. The onions will embed into the beef as it caramelizes, sending waves of mouthwatering aroma through your kitchen.
Step 5: Flip, Cheese, and Crisp
After about 2 minutes, flip the patty—onions and all. Give it a gentle press to encourage further browning, then curtain the burger with a slice of cheddar or American cheese. Cook for another 1–2 minutes, just enough for the cheese to melt and those edges to reach peak crispiness. Repeat the process for the remaining beef balls.
Step 6: Assemble and Enjoy
Place each cheesy, onion-studded patty onto a toasted bun. Add any desired toppings and condiments—from crunchy pickles to creamy mayo and juicy tomato slices. Serve your Garlicky Onion Smash Burger immediately while the cheese is melty and each bite promises savory perfection.
How to Serve Garlicky Onion Smash Burger

Garnishes
A sprinkle of freshly chopped parsley or chives makes your Garlicky Onion Smash Burger pop with color and a touch of freshness. For classic burger flair, stack on bright dill pickles, vibrant lettuce leaves, or a juicy tomato slice to balance all those bold, rich flavors.
Side Dishes
No burger experience is complete without fun sides. Crispy shoestring fries, a crunchy slaw, or even homemade kettle chips turn this into a diner-style meal at home. For something lighter, go for a tangy cucumber salad or sweet corn on the cob to complement all the savory goodness of your Garlicky Onion Smash Burger.
Creative Ways to Present
Try serving your Garlicky Onion Smash Burgers slider-style on mini buns for parties. For a picnic twist, wrap each assembled burger in parchment for easy, mess-free enjoyment. Or build a burger bar with different topping options, letting everyone customize their smash burger masterpiece!
Make Ahead and Storage
Storing Leftovers
If you have leftovers (which honestly, rarely happens with these), store the patties in an airtight container in the fridge for up to 3 days. Keep buns and toppings separate to maintain the best textures and flavors.
Freezing
The burger patties freeze beautifully before or after cooking. Lay them between parchment sheets in a freezer bag, squeezing out as much air as you can. They’ll keep well for up to a month—just thaw in the fridge before reheating or cooking.
Reheating
To reheat, pop cooked patties back onto a hot skillet for a minute or two per side, or briefly warm in the microwave. Toast your buns fresh to bring back that wonderful crunch, then reassemble with your favorite toppers for a revived Garlicky Onion Smash Burger experience.
FAQs
Can I use another type Main Course
Absolutely! While beef gives the classic taste and texture, you can try ground turkey, chicken, or even a meatless alternative for your Garlicky Onion Smash Burger. Just be aware that leaner meats may need extra oil to achieve those signature crispy edges.
How thin should I smash the patties?
For that gorgeous crispy crust, smash the patties until they’re about a quarter inch thick. The thinner you go, the more surface area for browning and those delicious craggy bits!
Do I have to use a cast iron skillet?
Cast iron is ideal for holding and distributing high, even heat, which is why it’s so perfectly suited to the Garlicky Onion Smash Burger. If you don’t have one, any heavy-bottomed skillet or a flat griddle will work in a pinch.
Can I prep anything ahead for a crowd?
Yes! You can shape the beef balls and slice the onions in advance, then keep them chilled until you’re ready to cook. This makes it super simple to whip up a fresh batch of Garlicky Onion Smash Burgers on the spot.
What’s the best cheese for meltiness?
American cheese is the classic because it melts into a perfectly gooey cloak over the patty, but sharp cheddar is amazing for a bit more bite. Honestly, your favorite melty cheese will work deliciously here!
Final Thoughts
If you love burgers that are all about bold flavors, sizzling edges, and gooey cheese melts, you owe it to yourself to try this Garlicky Onion Smash Burger. It’s a fun, fast way to level up burger night and put a smile on everyone’s face. Fire up that skillet and give it a try—you won’t regret it!
