🍔 Backyard Pickled Onion Burger

/

If you’re ready to take your burger game to the next level, this Backyard Pickled Onion Burger delivers everything you want in one bite — juicy, smoky beef, creamy homemade sauce, melted cheese, and tangy, homemade pickled onions that bring it all to life. It’s the kind of burger that doesn’t just taste good — it feels like summer around the grill.

The Story Behind the Recipe

This recipe was born out of a backyard experiment that went way better than expected. I had a batch of quick-pickled onions from the night before, a bag of brioche buns, and some fresh 80/20 ground beef waiting in the fridge. The idea hit — what if I combined the sharp bite of pickled onions with the rich, charred flavor of a burger fresh off the coals?

The result? Pure magic. The onions cut through the richness of the beef, the homemade sauce tied everything together, and the grilled brioche added the perfect buttery crunch. This burger became a Delmarva Backyard favorite — bold, simple, and full of character.

Burger Ingredients:

  • 2 lbs Ground Beef (80/20 blend for flavor & juiciness)

  • Kosmos Cow Cover Dry Rub

  • 4 Brioche Burger Buns

  • 1 Stick Unsalted Butter (melted)

  • 1 tsp Garlic Powder

  • 4 Slices Gouda Cheese

Toppings:

  • 1 Tomato, diced

  • 1 Head of Romaine Lettuce, chopped

  • Homemade Pickled Onions (recipe below)

Homemade Burger Sauce:

  • 2 Tbsp Mayo

  • ½ tsp Dijon Mustard

  • 1 tsp A1 Steak Sauce (or any steak sauce)

  • ½ tsp Worcestershire Sauce

Quick Pickled Onions

Ingredients:

  • 1 Red Onion, thinly sliced

  • 1 cup White Vinegar

  • 1 cup Water

  • 2 Tbsp Sugar

  • 1 tsp Salt

Instructions:
1️⃣ Bring the vinegar, water, sugar, and salt to a simmer in a small pot.
2️⃣ Add the sliced onions and remove from heat.
3️⃣ Let them sit for at least 1–2 hours, or refrigerate overnight for best flavor.

Instructions

1️⃣ Prep the Sauce
In a small bowl, mix together mayo, Dijon, steak sauce, and Worcestershire sauce. Refrigerate while you prep the rest — this helps the flavors meld and thicken.

2️⃣ Shape the Patties
Use a burger ring to shape four evenly sized patties. Round out the edges slightly with your hands for a more natural look.

3️⃣ Season Generously
Sprinkle Kosmos Cow Cover Rub on both sides of each patty and pat it in gently.

4️⃣ Preheat the Grill
Get your charcoal grill ready for direct cooking at 500°F (260°C). Let the grates preheat to develop that perfect sear.

5️⃣ Grill the Burgers
Place the burgers directly over the coals and press them lightly to ensure good grate contact. Grill for 3–4 minutes per side, flipping once.

6️⃣ Toast the Buns
Melt butter and mix in garlic powder. Brush on brioche buns and toast them on a cooler section of the grill until golden and slightly crispy.

7️⃣ Melt the Cheese
Add a slice of Gouda to each burger in the final minute of cooking. Close the lid briefly to let it melt.

8️⃣ Rest and Build
Remove burgers and let them rest for 2–3 minutes. Assemble in this order:

  • Bottom bun

  • Burger with melted cheese

  • Romaine lettuce

  • Pickled onions

  • Diced tomato

  • A tablespoon of burger sauce

  • Top bun

Slice in half, and enjoy the perfect balance of smoky, tangy, and savory goodness.

Pro Tips for the Perfect Backyard Burger 💡

🍔 Shape Matters: A burger ring keeps the patties even, helping them cook perfectly.
🔥 Avoid Pressing Down: Don’t press the burgers while cooking — it releases the juices.
🧅 Pickle Ahead: Make the pickled onions the day before for deeper flavor.
🥬 Crisp Texture: Add lettuce under the burger to keep the bun from getting soggy.
🧄 Butter the Buns: Garlic butter + toasted brioche = unbeatable flavor.

Why This Recipe Works

This burger nails the balance of flavors: smoky from the grill, creamy from the sauce, and bright from the pickled onions. Every layer serves a purpose — the sauce ties it all together, the cheese adds richness, and the onions cut through the heaviness. It’s simple backyard cooking done right — bold, flavorful, and made for sharing with a cold beer in hand.
