What Ingredients You Will Need

This recipe uses straightforward, wholesome ingredients that combine to create bold flavors and satisfying textures without fuss. Most of these are pantry staples, and if you’re lucky, you’ve got everything on hand already.

• For the Smash Burgers:
  • Ground beef (80/20 blend preferred, about 1 pound/450 grams) – the fat content is key for juicy patties
  • Salt (kosher or sea salt) – to season generously
  • Freshly ground black pepper – for that bite
  • Cheddar cheese slices (optional, about 4 slices) – sharp or mild, your call
  • Soft burger buns (4) – brioche or potato buns work beautifully
  • Butter (unsalted, softened) – to toast buns on the griddle
• For the Caramelized Onion Jam:
  • Yellow onions (2 large, thinly sliced) – small-curd onions give the best sweetness
  • Olive oil (2 tablespoons) – a good quality brand like California Olive Ranch makes a difference
  • Brown sugar (1 tablespoon) – to help caramelize and add depth
  • Balsamic vinegar (1 tablespoon) – adds a subtle tang and balances the sweetness
  • Fresh thyme (1 teaspoon, chopped) – optional but highly recommended for aroma
  • Salt and pepper to taste
• Optional Toppings:
  • Leaf lettuce or arugula – adds a fresh crunch
  • Tomato slices – ripe and juicy
  • Pickles – for that classic tang
  • Mustard or mayo – if you want an extra layer of flavor

Substitution tip: If you want a gluten-free option, swap the buns for your favorite gluten-free bread or lettuce wraps. And if dairy’s off the table, skip the cheese or use a plant-based alternative. When I’m in a pinch, I’ve even swapped Greek yogurt mixed with a little lemon for mayo to keep things tangy and fresh.

Equipment Needed

• Blackstone Griddle: The star of the show for that perfect sear and easy smash technique. No Blackstone? A heavy cast-iron skillet works well too, though you miss out on the griddle’s large cooking surface.
• Sturdy Spatula or Burger Press: Essential for smashing the patties evenly and flipping without breaking them.
• Mixing Bowls: For prepping the onion jam and mixing seasonings.
• Sharp Knife: For slicing onions thinly and prepping toppings.
• Cutting Board: A stable surface for prep.

Personally, I love using my cast-iron spatula with a flat edge; it helps me get that satisfying crust without mangling the patty. For toasting buns, the Blackstone’s side burner or a small pan works just fine. If budget’s a concern and you don’t have a Blackstone griddle, a well-seasoned cast iron pan can still deliver excellent results, just work in batches.

Preparation Method

1. Prepare the Caramelized Onion Jam (about 25 minutes): Heat the olive oil in a medium skillet over medium heat. Add the thinly sliced onions and a pinch of salt. Cook slowly, stirring occasionally, until they start to soften and turn golden brown (about 15 minutes). Add the brown sugar and balsamic vinegar, stirring well. Continue cooking for another 5-7 minutes until the onions are jammy and slightly sticky. Stir in fresh thyme, taste, and season with pepper and more salt if needed. Set aside to cool slightly.
2. Preheat the Blackstone Griddle: Crank the heat to medium-high and let it get hot—this usually takes about 5 minutes. The surface should be hot enough to sizzle when the beef hits it.
3. Form the Burger Balls: Divide the ground beef into 4 equal portions, about 4 ounces (113 grams) each. Gently roll them into loose balls without packing too tight; you want air pockets to keep the meat juicy.
4. Toast the Buns: Lightly butter the cut sides of your buns. Once your griddle is hot, place buns cut side down and toast until golden brown (about 1-2 minutes). Remove and set aside.
5. Smash the Patties: Place one beef ball on the griddle. Using your spatula or a burger press, press down firmly to about ½ inch (1.25 cm) thickness. Hold the pressure for 10-15 seconds to create that crispy crust. Season the exposed side with salt and pepper immediately.
6. Cook the First Side: Let the patty cook undisturbed for 2-3 minutes, watching for a deep brown crust forming. You can peek underneath to check.
7. Flip and Add Cheese: Flip the patties carefully. Immediately lay a slice of cheese on top if using. Cook for another 1-2 minutes until cheese melts and the patty is cooked through but still juicy.
8. Assemble the Burgers: Spread a generous layer of caramelized onion jam on the bottom bun, add the patty, then your favorite toppings like lettuce, tomato, and pickles. Cap it with the top bun.
9. Serve Immediately: These burgers are best enjoyed hot off the griddle with a side of crispy fries or a fresh salad like the Fresh Southwest Chipotle Salad to balance the richness.

Pro tip: Don’t crowd the griddle. Work in batches if needed to keep the temperature high and the crust perfect. Also, when smashing, don’t press too thin or you risk drying out the patty.

Cooking Tips & Techniques

Smash burgers might look simple, but getting the perfect crust and juicy interior takes some finesse. Here’s what I’ve learned:

• Use High Heat: The Blackstone griddle’s heat is your best friend. It creates that coveted Maillard reaction that turns the patty edges beautifully crispy.
• Don’t Overwork the Meat: Handle the ground beef gently. Over-mixing leads to dense burgers.
• Press, Don’t Squish: When smashing, press firmly but hold steady for a few seconds instead of pounding repeatedly. This helps the patty keep its shape and develop an even crust.
• Season After Smashing: Salt the patty once it’s flattened—this helps with crust formation and flavor.
• Patience is Key: Resist the urge to flip too soon. Let the crust form fully before flipping for the best texture.
• Onion Jam Magic: Caramelizing onions slowly over medium heat brings out natural sugars. Adding balsamic vinegar adds a subtle tang that cuts through the beef’s richness.
• Multitasking: While onions caramelize, prep your burger balls and toast buns so you’re not scrambling at the last minute.

I’ve made the mistake of rushing the onion jam or smashing too hard, and trust me, the difference is night and day. Stick with these tips, and you’ll have consistent, mouthwatering results every time.

Variations & Adaptations

Want to play around with this recipe? Here are some variations that keep things interesting:

• Cheese Options: Swap cheddar for pepper jack or Swiss to add a different flavor profile. For dairy-free, try a smoked vegan cheese.
• Protein Tweaks: Use ground turkey or chicken for a leaner option; just be sure to add a bit of olive oil to keep patties juicy.
• Seasonal Onion Jam: In fall, mix caramelized onions with roasted apples or pears for a seasonal twist.
• Spice It Up: Add a pinch of smoked paprika or cayenne to the beef before smashing for a subtle kick.
• Cooking Method: Don’t have a Blackstone griddle? Try cooking smash burgers on a cast iron skillet or even a flat top grill.

Once, I swapped in red onions for the jam and added fresh rosemary—it turned out surprisingly well and gave the burger an herbaceous layer that my family loved. Feel free to experiment and make this recipe your own.

Serving & Storage Suggestions

These burgers are best served immediately while the patties are still juicy and the buns perfectly toasted. But if you have leftovers (hey, it happens), here’s how to keep them tasting great:

• Serving: Keep it classic with crispy fries or try a zesty side like the Creamy Chicken Caesar Pasta Salad for a filling meal.
• Storage: Store leftover patties and onion jam separately in airtight containers in the fridge for up to 3 days.
• Reheating: Reheat burgers gently in a skillet over medium heat to keep the crust intact; rewarm onion jam in a microwave or saucepan.
• Flavor Development: The onion jam actually tastes even better after a day or two, so making it ahead can deepen the flavor.

FAQs About Savory Blackstone Smash Burgers with Caramelized Onion Jam

Can I make the caramelized onion jam ahead of time?

Absolutely! The jam actually tastes better after sitting overnight in the fridge. Just warm it slightly before serving.

What if I don’t have a Blackstone griddle?

No worries. A heavy cast-iron skillet or flat top grill works well for smashing and searing the patties.

How do I prevent the patties from sticking to the griddle?

Make sure your griddle is properly heated and lightly oiled before adding the beef. Don’t try to flip too soon; the crust helps release the patty naturally.

Can I use leaner ground beef?

You can, but keep in mind lean beef might yield drier burgers. Adding a bit of olive oil or mixing in some ground pork can help keep them juicy.

What are good side dishes to serve with these burgers?

Crispy fries, onion rings, or a fresh salad like the Fresh Southwest Chipotle Salad complement the richness perfectly.
