The Recipe: Onion Smash Burgers

For the Seasoned Beef:

• 1 lb ground beef (80/20 blend for best flavor!)

• 1 tbsp ketchup

• 1 tbsp BBQ sauce

• 1 tsp Worcestershire sauce

• ½ tsp onion powder

• ½ tsp garlic powder

• ½ tsp garlic salt

• ½ tsp salt

• ½ tsp black pepper

• 1 tsp olive oil

For the Burgers:

• 1 large onion, thinly sliced

• 4 burger buns (brioche is great!)

• Cheese of choice (American, cheddar, or pepper jack)

• Butter for toasting buns

Instructions:

Step 1: Season the Beef

1. In a bowl, mix ground beef with ketchup, BBQ sauce, Worcestershire sauce, and seasonings.

2. Gently mix until combined—don’t overwork the meat!

📌 Pro Tip: For extra flavor, let the seasoned beef rest for 10–15 minutes before cooking.

Step 2: Prep the Onions & Shape the Patties

3. Thinly slice the onions and set aside.

4. Divide the beef into 4–6 loosely packed balls (about 2.5 oz each for thinner patties or 4 oz each for thicker ones).

📌 Smash burgers work best with loosely packed meat—this helps create the crispy edges!

Step 3: Cook the Burgers

5. Heat a cast-iron skillet or griddle over medium-high heat.

6. Add a little butter or oil, then toss in the sliced onions. Cook for 1–2 minutes until they soften slightly.

7. Place a beef ball on top of the onions and use a burger press, large measuring cup, or spatula to smash it down until about ¼-inch thick.

📌 The key to crispy edges? Smash once and don’t press again!

8. Cook for 2–3 minutes until the edges get golden and crispy.

9. Flip, place cheese on top, and cook for another 1–2 minutes until the cheese melts.

Step 4: Assemble & Serve

10. Toast the burger buns with butter in the skillet.

11. Stack the cheesy onion smash patties onto the buns.

12. Top with extra BBQ sauce, ketchup, or pickles (optional but delicious!).

13. Serve immediately with fries, chips, or a side salad.

📌 Pro Tip: Double up the patties for a classic smash burger experience!
