Why You Will Love these Burgers
- They are full of spicy Tex-Mex flavor.
- Cooking them on flat top griddle makes them a caramelized outside and juicy inside.
- You can cook everything on the griddle and even toast the buns!
Advantages of Cooking Burgers on a Griddle
I love the Blackstone griddle I got this spring and have been making all kinds of meals on it. And for me using a flat top griddle for burgers is better than using a grill.
My favorite thing about using the griddle is I can cook all kinds of toppings along with the burgers. If I want bacon cheeseburgers I can cook some bacon right beside the burgers and melt the cheese on top.
Or I can cook peppers and onions like in these fajita burgers. You can also toast the buns on the griddle, which makes them nice and crispy in just a couple minutes. Toasted buns and extra toppings take burgers from a boring to exciting!
No Griddle? Make Air Fryer Burgers instead!
In addition I don’t have to worry about food falling down the grill grates and the griddle temperature is easier to control than a grill. All in all I have completely abandoned my grill this summer in favor of my Blackstone griddle!
Key Ingredients
**For exact amounts needed see the recipe card below.
Ground beef – I use 80% lean ground beef for my burgers. The fat is part of what makes the burgers juicy and flavorful and I find 80% is a good middle ground with enough fat but not too much. Some people prefer ground chuck, which is around 70% lean.
Onion – A sweet onion such as a Vidalia gives the best fajita flavor.
Peppers – Any color peppers will work for the fajita veggies. I like to use red or yellow (or both) since they are sweeter and make the burgers prettier.
Avocado – Avocado on the buns is essential for fajita burgers!
Spices – I mixed chili powder, paprika, cumin, oregano, garlic powder and onion powder together to flavor the burgers. You can also use a premade fajita spice mix if you prefer.
How to Make Fajita Griddle Burgers
1. Prep
Turn your griddle on to preheat on medium high heat. Then thinly slice the peppers and onions into long strips. Mash the avocado up and mix it with a tablespoon of salsa verde or lime juice.
Put the ground beef in a medium bowl and add the chili powder, paprika, cumin, oregano, garlic powder and onion powder. Knead the spices into the beef to mix them well. Separate the meat into four burgers and press them into patties.
Tip
Tip: For the best burger texture handle the beef as little as possible. Make sure the seasoning gets distributed, but don’t over mix it.
2. Cook
Take everything outside to the griddle, including the buns. If you have multiple zones on your griddle set one on medium low for the veggies and one on medium high for the burgers. If you only have one zone just use medium for both.
Use a squeeze bottle to add a little oil to the griddle and spread it around. Then toss the onions and peppers in the oil and let them start to soften. I like to cook the veggies for 4 minutes before adding the burgers. Toss the peppers and onions occasionally with tongs so that they cook on all sides.
After about 4 minutes add the burgers to the griddle. Let them cook for about 3 minutes per side. If you want well done burgers then cook them for 5 minutes per side.
When the burgers are almost done put the buns, cut side down, on the grill. Let them toast for about 1 minutes so that they have a nice crispy interior.
3. Build the Flat Top Burger
Spread some of the avocado mixture on the bottom bun, then top it off with a burger and peppers and onions and serve.
Tip: Make sure you clean your griddle soon after cooking. Check out the directions from Blackstone on how to care for a griddle.
How to Serve
Some other suggested toppings for these fajita burgers are:
- Cheddar cheese
- Cilantro
- Tomato slices
- Lettuce
- Pepperjack cheese
- Salsa
These burgers are, of course, delicious served with French fries or potato chips. You can make a more nutritious meal by adding a green salad or some fruit. Corn on the cob is another great summer side dish for burgers!
How to Store
If you have leftover fajita burgers you can store them in the refrigerator for 2-3 days. The easiest way to reheat them is to put them in an air fryer at 360 degrees F for 5 minutes.
Variations
- Make these with ground turkey or ground chicken for a lower fat burger that still has lots of flavor.
- Using a jar of premade fajita spices can simplify the recipe even more.
