Ingredients You’ll Need
The magic of this Garlicky Onion Smash Burger Recipe lies in the simplicity and quality of its ingredients. Each one plays a vital role—bringing out rich savoriness, perfect juiciness, and that beautiful golden color we all adore on a smash burger.
- 1 pound ground beef 80/20: This ratio balances flavor and fat for juicy, tender patties with a crispy crust.
- 1 large yellow onion, thinly sliced: Adds sweetness and a slight tang that softens while cooking, enhancing the beef.
- 3 cloves garlic, minced: Provides a warm, aromatic note that infuses the onions and patties.
- 1 tablespoon vegetable oil: Ensures the onions cook evenly without sticking, plus aids in the perfect sear.
- 1 tablespoon butter: Adds richness and helps create that mouthwatering, caramelized onion flavor.
- 1 teaspoon salt, divided: Seasoning at different points helps draw out moisture and deepen flavor.
- 1 teaspoon black pepper, divided: Adds subtle heat and complexity.
- 4 slices American or cheddar cheese: Melts beautifully over the patties for creamy, cheesy goodness.
- 4 hamburger buns: Soft yet sturdy, perfect for holding up all the delicious fillings.

- 1 teaspoon mustard (optional): Adds a bit of sharpness and depth to the sandwich.
How to Make Garlicky Onion Smash Burger Recipe
Step 1: Preparing Your Pan and Ingredients
Start by heating a large cast iron skillet or griddle over high heat until it’s screaming hot. This is essential for getting that perfect sear and the trademark crispy edges of a smash burger. While the pan warms up, gently divide your ground beef into four loose balls. Keep the meat loose—overworking it will make your burgers tough and chewy.
Step 2: Cooking the Onions and Garlic
Add the vegetable oil evenly into your hot skillet, then place the thinly sliced onions in the pan. Let them cook undisturbed for 2 to 3 minutes until they start to soften and turn translucent. Now add the butter and minced garlic, cooking everything together for about 30 seconds until the kitchen fills with that irresistible garlicky aroma. Push this mixture to one side of the pan to make room for the patties.
Step 3: Smashing and Seasoning the Patties
Place each ball of beef into the pan, then smash it flat immediately with a sturdy spatula. This quick smash is what forms the delicious crust that smash burgers are known for. Sprinkle half of your salt and black pepper evenly over the patties. Let the burgers cook undisturbed for 2 to 3 minutes until the undersides are deeply browned and crispy.
Step 4: Flipping and Adding Cheese and Onion
Flip the patties carefully, then top them with the garlicky onion mixture. Season with the remaining salt and pepper, then place a slice of cheese on each patty. Cook for another 1 to 2 minutes, just long enough for the cheese to melt and the patties to finish cooking through perfectly.
Step 5: Toasting Buns and Assembling
Toast your hamburger buns lightly if you like that extra bit of crunch and warmth. Spread mayonnaise and mustard (if using) on the buns, add the cheesy patties topped with garlicky onions, and serve immediately so everything stays warm and juicy.
How to Serve Garlicky Onion Smash Burger Recipe
Garnishes
This Garlicky Onion Smash Burger Recipe is wonderfully versatile when it comes to garnishes. Crisp lettuce, slices of ripe tomato, or tangy pickles make excellent additions to brighten the burger and add fresh contrast to the rich, savory patties.
Side Dishes
Pair these burgers with classic fries for an all-time favorite combo, or go for healthier options like a simple green salad or roasted vegetables. Coleslaw with a hint of vinegar also complements the richness with a refreshing crunch.
Creative Ways to Present
If you want to turn this dish into a real showstopper, consider serving the patties open-faced with extra garlicky onions piled high, or even create mini slider versions for a party platter. Wrapping the burgers in parchment paper and tying with a string adds a rustic touch that guests will adore.
Make Ahead and Storage
Storing Leftovers
Once cooled, wrap leftover patties and onions separately in airtight containers and refrigerate. They should keep well for up to 3 days, allowing you to enjoy the Garlicky Onion Smash Burger Recipe again with minimal effort.
Freezing
If you want to make these burgers in bulk, you can freeze the cooked patties without cheese. Layer them with parchment paper and place in a freezer-safe bag for up to 3 months. Freeze onions separately if possible to avoid sogginess.
Reheating
Reheat the patties gently in a skillet over medium heat to preserve their texture. Add fresh cheese and warm the onions separately before assembling to recapture the original deliciousness of the Garlicky Onion Smash Burger Recipe.
FAQs
What type of ground beef is best for this smash burger?
An 80/20 blend of ground beef is ideal because it has the perfect fat content to keep the patties juicy while allowing for a crispy sear.
Can I use other types of cheese besides American or cheddar?
Absolutely! Swiss, pepper jack, or even a blue cheese crumble can add unique flavors, but keep in mind that meltability varies.
Is it necessary to use a cast iron skillet?
While not mandatory, a cast iron skillet is best for retaining high heat and achieving the signature crust that defines the Garlicky Onion Smash Burger Recipe.
How do I prevent the burgers from drying out?
Handle the meat gently without over-packing, and avoid pressing the patties down after the initial smash. Cooking them quickly at high heat also seals in the juices.
Can I make this recipe gluten-free?
Yes! Simply swap regular buns for gluten-free buns, and ensure all condiments used are gluten-free as well.
