I think that grilling is one of the most exciting ways to enjoy beef. Whether cooking on gas or charcoal, simply grilling provides maximum flavor. And, while the United States is a melting pot of people and cultures, it turns out one of the things we share in common is our love of beef and of grilling! Who knew? So what could be more patriotic than beef burgers on the grill? 

I know that burgers are my first thought anyway when tasked with coming up with the menu for any summer day that requires us to fire up the barbecue (for us, that’s most days really!).

Typically we have a big gathering for the first holiday of the summer, and while we almost always grill out all-beef burgers, this year I wanted to give them a little twist — a Greek twist at that. (You all know my love of all foods Greek.) It’s so much more fun to “dress up” your beef burger, and, while these might seem like a totally different break from the norm, trust me when I say that everyone will enjoy them!

Are you ready to get your first cookout of the season going? I know I am! The one thing that unites us right now is our love of tradition, and luckily one of the great traditions of summer is cookouts! Across all 50 states and a million tastes, Americans can join together, united behind the grill with their favorite protein. Because beef is what’s for dinner—and this will always unite us.

So why not grill up to celebrate National Beef Burger Day this fan favorite but with a twist? These Greek burgers with feta and spinach will have your cookout guests raving!

First, make the tzatziki sauce by stirring together all of the ingredients, covering, and chilling in the fridge until you’re ready to use.

Next, start to pull together the burger patties by mixing together all the ingredients in a bowl with the ground beef. Divide the mixture into four sections, and shape each section into a ball, then a patty, ready for the grill!

Preheat the grill, then place the patties on the grill and leave a few inches between them to make sure they cook evenly. Cook each side for 5-6 minutes or until they are at least 160 degrees.

Take them off the grill and let them rest before assembling with all the delicious toppings. Resting the meat before serving—even if you’re hungry—is worth the wait because it prevents all those tasty juices from draining onto your plate. Five minutes is an appropriate rest time for this burger recipe.

After resting, add the burger patties to the ciabatta buns, top with tzatziki sauce, tomatoes, onions, fresh spinach and arugula, and cucumber ribbons and serve!

    • Ground Beef is done when cooked to medium (160°F).
    • Always wash your hands thoroughly before and after handling raw meat. 
    • Use separate plates, cutting boards, utensils for raw vs. cooked foods to prevent cross contamination.
    • Use an instant-read thermometer to ensure beef is properly cooked.
    • Although I like to let burgers (and other beef) rest after they’ve been cooked, it’s not advised to let Ground Beef come up to room temperature before cooking for food safety reasons. Once you’ve mixed in the seasonings and feta, it’s best to just pop them right onto the grill. 
    • For charcoal grills, read your owner’s manual as to how high to stack up the coals. 
    • One flip of the burger is usually all you need. Go ahead and let it cook, undisturbed, for 5-6 minutes before flipping. This will also keep it from sticking to the grates if you try to flip before it’s ready. 
    • If you do see some charring or burning start to occur, simply turn down the heat or move the burgers off the flame to another part of the grill until the flare up dies down. 
    • Beef cooks best at a medium heat. There’s no need to rush the grilling process. Cooking at a medium heat allows beef to achieve caramelization while still developing rich flavors and avoiding charring.
