How to Make:

Quick Overview

This recipe is straightforward: form loose balls of ground chuck, smash them on a hot griddle, season, and cook until a deep brown crust forms. The magic comes from the contrast of crisp edges and juicy center, plus the creamy baconnaise and sweet caramelized onions. Prep and cook time are fast — plan for about 15 minutes active prep and 10 minutes cooking time.

Approximate time: 25 minutes total (15 minutes prep, 10 minutes cook)

Ingredients

• 2 lbs (900 g) ground chuck (80/20), loosely divided into four portions
• 2 white onions, paper-thin sliced (about 1/8-inch slices)
• Salt to taste (start with 1/2 tsp and adjust)
• Black pepper to taste (freshly ground recommended)
• Garlic powder to taste (start with 1/4 tsp)
• 1/2 cup Baconnaise sauce (store-bought or homemade), room temperature for easy spreading
• 4 burger buns, split and toasted if desired
• 4 slices American or cheddar cheese (optional)
• 2 tablespoons vegetable oil or neutral oil for cooking onions and griddle lubrication

Directions

1. Preheat a griddle or heavy skillet over medium-high heat until very hot. If using a cast-iron griddle, give it 5–7 minutes to heat thoroughly. Lightly oil the surface.
2. Divide the ground chuck into four equal portions and loosely form each into a ball — do not overwork the meat. Keeping the meat loose helps create a tender patty.
3. Place the meat balls on the hot cooking surface, leaving space between them. Immediately smash each ball down with a heavy spatula or burger press to form thin patties (about 1/4-inch thick). Hold the spatula firmly to maintain contact for a few seconds to help the crust develop.
4. Season each patty with salt, black pepper, and a light sprinkle of garlic powder right after smashing. This ensures the seasoning adheres to the hot meat.
5. Cook the patties for about 3–4 minutes without moving them, until a deep brown crust forms on the bottom. Use a thin spatula to peek for the crust before flipping.
6. Flip the patties carefully and cook for an additional 2–3 minutes. If using cheese, place a slice on each patty during the last minute of cooking and cover briefly to melt.
7. While the burgers cook, heat 1 tablespoon of oil in a separate pan over medium heat. Add the paper-thin sliced onions and cook, stirring occasionally, until soft and caramelized — about 10–12 minutes. Lower the heat if they brown too quickly.
8. Assemble the burgers: spread baconnaise on the bottom bun, place the cooked patty, top with caramelized onions, add any extra toppings, and finish with the top bun. Serve hot and enjoy!

What to Serve With

• Crispy fries or sweet potato fries for classic comfort pairing
• A light, tangy coleslaw to cut through the richness
• Pickle spears or sliced dill pickles for acidity and crunch
• Ice-cold beer, a milkshake, or a citrusy iced tea for refreshing balance
• A simple garden salad with a lemon vinaigrette to add freshness

Top Tips for Perfecting

• Use 80/20 ground chuck for the right fat content — it keeps patties juicy and helps crisp the edges.
• Don’t overwork the meat when forming balls; loose meat gives the best texture.
• Make sure the griddle is hot — a cool surface will steam, not sear, the meat.
• Press once and hold for a few seconds to maximize contact; avoid smashing repeatedly.
• For sweeter onions, add a pinch of salt and a teaspoon of sugar while caramelizing.
• If you don’t have baconnaise, mix mayo with cooked, finely chopped bacon and a touch of smoked paprika as a quick substitute.
• Avoid stacking burgers too many layers high; thin patties are meant to be enjoyed in a 1–2 patty sandwich.

Storing and Reheating Tips

• Refrigeration: Store leftover patties and onions separately in airtight containers for up to 3 days. Keep baconnaise chilled in a sealed jar for up to one week.
• Freezing: Freeze cooked patties in a single layer on a tray until firm, then transfer to a freezer bag for up to 2 months. Thaw in the fridge before reheating.
• Reheating: Reheat patties in a hot skillet for 1–2 minutes per side to restore some crust. Avoid microwaving if you want to keep texture; if microwaving, use short bursts and then sear briefly. Reheat caramelized onions gently in a pan over low heat.

FAQs

What is the best meat for smash burgers?
Ground chuck with an 80/20 fat ratio is ideal because it provides enough fat for flavor and crust without being too greasy.

Can I make baconnaise at home?
Yes. Mix mayonnaise with finely crumbled cooked bacon, a little garlic powder, and smoked paprika. Adjust to taste.

How thin should I smash the patties?
Aim for about 1/4-inch thickness after smashing. Thin patties ensure a maximum crust-to-center ratio and quick cooking.

Can I prepare the caramelized onions ahead of time?
Absolutely. Caramelized onions store well in the fridge for up to 4 days and actually develop deeper flavor when made ahead.

Are smash burgers healthy?
They are indulgent — higher in fat due to the 80/20 beef and baconnaise. You can lighten them by using leaner beef, less sauce, or whole-grain buns, and adding fresh veggies.
