How to Make Garlicky Onion Smash Burger Recipe
Step 1: Prep the Beef and Onions
Start by dividing your ground beef into four equal balls. While your skillet heats up, slice the onion finely for even caramelization. These initial steps set the stage for the juicy, flavorful patties and sweetly garlicky onions that define this recipe.
Step 2: Sauté the Onions
In a hot skillet or griddle, melt the butter and add the sliced onions. Cook over medium-high heat for about 5 to 7 minutes until they’re golden-brown and caramelized. This step transforms the raw onion’s sharpness into a tender, sweet topping bursting with flavor. Once done, remove them from the pan and set aside.
Step 3: Smash and Season the Patties
Turn the heat to high to ensure a sizzling sear. Place each beef ball onto the skillet and immediately smash it down firmly with a spatula or burger press. This smashing is what gives the burger its signature crispy edges. Season each patty generously with garlic powder, salt, and black pepper right after smashing.
Step 4: Cook the Patties with Cheese and Onions
Cook each smashed patty for 2 to 3 minutes until crispy brown edges form, then flip carefully. Immediately add a slice of cheese on top of each patty and spoon a generous amount of those caramelized onions on top. Let the cheese melt for about 1 to 2 minutes while the burger finishes cooking.
Step 5: Toast the Buns and Assemble
For that irresistible crunch and warmth, toast your burger buns in the skillet or toaster while the patties finish. Once everything is ready, assemble your burgers by layering each patty with the sautéed onions on the toasted buns and add your favorite toppings for a personalized finish.

Garnishes
Simple toppings like crisp lettuce and fresh tomato slices add brightness and texture, while pickles contribute a tangy snap that pairs perfectly with the garlicky sweetness of the onions. Don’t forget your favorite condiments like creamy mayo or classic mustard to complement every bite of this smash burger.
Side Dishes
This Garlicky Onion Smash Burger Recipe shines alongside crispy fries or a fresh green salad for balance. For a smoky touch, grilled vegetables or corn on the cob also make fantastic sides.
Creative Ways to Present
Feel adventurous? Serve your burger with a side of onion rings or stuff the patties inside lettuce wraps for a low-carb option that still holds all the flavor. You can also transform it into slider form for parties or serve open-faced with a fried egg on top for brunch vibes.
Make Ahead and Storage
Storing Leftovers
Store any leftover patties and onions in an airtight container in the refrigerator for up to 3 days. Keep burger buns separate to avoid sogginess and assemble just before eating to enjoy the freshest taste and texture.
Freezing
You can freeze cooked patties wrapped tightly in plastic wrap or foil and stored in a freezer bag for up to 2 months. Thaw overnight in the refrigerator before reheating to maintain juiciness.
Reheating
To reheat, gently warm the patties in a skillet over medium heat until heated through, then add cheese if desired to melt again. Toast the buns fresh, and reassemble with your leftover caramelized onions and toppings for a quick meal.
FAQs
Can I use fresh garlic instead of garlic powder?
Absolutely! Fresh minced garlic sautéed with the onions adds an even more vibrant garlic flavor. Just be careful not to burn it, as garlic can turn bitter when overcooked.
What’s the best beef blend for smash burgers?
The classic 80/20 ground beef is perfect for smash burgers because the fat content keeps the patties juicy while achieving that crispy edge when cooked at high heat.
Can I make this recipe gluten-free?
Yes, simply use gluten-free burger buns and check your toppings and condiments to ensure they don’t contain gluten. The rest of the recipe is naturally gluten-free.
Why do we smash the burger patties?
Smashing the patties thin against a hot surface creates more contact with the skillet, resulting in a delicious caramelized crust without drying out the burger. It’s key to achieving that perfect smash burger texture.
Can I add other toppings to the Garlicky Onion Smash Burger Recipe?
Definitely! This burger is a fantastic base for endless creativity—try crispy bacon, sautéed mushrooms, avocado slices, or your favorite sauce to make it uniquely yours.
