Notes
Flavor Variations
- Extra Heat: Add cracked black pepper or a dash of hot sauce to the sauce
- Onion Lover: Smash burgers over thin-sliced onions
- Deli-Style: Add arugula or shredded iceberg
Recipe Notes
- Best Beef Ratio: Use 80/20 ground beef for maximum juiciness and crispy edges. Leaner beef won’t smash or caramelize as well.
- Horseradish Control: Prepared horseradish is powerful — start with 1 tablespoon and increase slowly if you like more heat.
- One Smash Only: Press the burger once when it hits the pan. Re-smashing forces out juices and dries the meat.
- Pan Temperature Matters: The skillet should be very hot before adding beef to get that signature smash-burger crust.
- Swiss Cheese Tip: Add cheese immediately after flipping so it melts smoothly without overcooking the burger.
- Pickle Balance: Dill pickles add acidity that balances the richness of the beef and sauce — don’t skip them.
- Bun Choice: Brioche or potato buns hold up best to the juicy burger and creamy horseradish sauce.
- Make-Ahead Sauce: The horseradish sauce can be made up to 2 days ahead and stored covered in the refrigerator.
Frequently Asked Questions
Can I make these smash burgers without a cast iron skillet?
Yes. A heavy stainless-steel skillet or a flat-top griddle works well. The key is using a surface that can retain high heat for proper browning.
Is horseradish sauce spicy?
Horseradish has a sharp, nasal heat rather than a lingering burn. When mixed with mayonnaise, it becomes creamy and balanced, making it approachable even for mild-heat lovers.
Can I prepare the horseradish sauce ahead of time?
Absolutely. The sauce can be made up to two days in advance and stored covered in the refrigerator. The flavor often improves as it rests.
What type of pickles work best for this burger?
Classic dill pickle chips or sandwich slices are ideal. Bread-and-butter pickles can be used if you prefer a touch of sweetness.
Can I cook these burgers on an outdoor grill?
Smash burgers are best cooked on a flat surface. If grilling, use a cast iron griddle or plancha placed directly over the grill grates.
What sides pair well with horseradish smash burgers?
French fries, kettle chips, onion rings, or a simple green salad all complement the bold, creamy flavors of this burger.
