Loaded BBQ Burger

I’m not joking about the “loaded” part of this Loaded BBQ Burger.

  • Onion ring? Check!
  • Bacon? Check!
  • Fresh avocado, tomato, and cheese? Check, check, and check!
  • Spicy BBQ Mayo to top it all off? Oh yes!

This Cowboy Burger is SO worth the calorie splurge! It’s one of my favorite burgers to make when I really just want to dig in and eat something unbelievably delicious. This is not for health-conscious days. This burger is for major pig out occasions, like game day and BBQs. Eat, get a little messy, and enjoy the flavors!

Spicy Mayo

One of my favorite parts of this loaded cowboy burger is the deliciously spicy mayo! It’s the perfect condiment for this BBQ burger. Regular mayonnaise, ketchup, mustard…no, those aren’t enough. We needed something with some extra amazing flavor to finish off this burger.

What’s in our spicy mayo?

  • Mayonnaise
  • BBQ Sauce
  • Red Pepper Flakes

That’s it! Just three simple ingredients to make it, and all you have to do is mix everything together. It’s so good, you’ll want to start eating it on everything. Every burger, every sandwich, go crazy!

How to Make Cowboy Burgers with Spicy Mayo

These grilled Cowboy Burgers are super easy to make. You’re looking at maybe a half hour tops to get them ready to eat. That’s good news for days when you’re SUPER hungry and the patience for intricate cooking is nowhere to be found.

How to make Loaded BBQ Burgers:

  1. Start by making that spicy mayo (combine mayo, BBQ sauce, & red pepper flakes) and setting it aside until you need it.
  2. Place the burger patties on a hot grill, and cook for 3-4 minutes on each side. Check here for tips on making the best grilled burgers.
  3. Add a slice of cheese to each burger about 1 minute before taking them off the grill and let it melt.
  4. Now it’s time to assemble the burgers! Spread the spicy mayo over the burger buns, then layer up lettuce, tomato, burger patty, 2 slices of bacon, 2 slices of avocado, 2 onion rings, and finish it off with more BBQ mayo.

Yuuuum. Are you drooling yet? These are some of the best burgers ever, filled with so much flavor and LOADED with amazing ingredients. I know you’re going to love them!
