Preparing Your Traeger Grill

Before you begin grilling, it’s important to properly set up your Traeger grill. Follow these simple steps to get started:

  1. Preheat the grill: Turn on your Traeger grill and set the temperature to around 325°F – 350°F. Allow the grill to preheat for about 15 minutes before placing the burgers on it.
  2. Clean the grill grates: Make sure your grill grates are clean, as this will prevent your burgers from sticking and promote even cooking.

Grilling Frozen Costco Burgers on a Traeger

Now that your grill is preheated, you’re ready to start grilling your frozen Costco burgers. Here’s how to do it:

  1. Season the burgers: Although Costco burgers come pre-seasoned, you can add additional flavor by seasoning them with Traeger Coffee Rub or a mixture of salt and pepper.
  2. Place the burgers on the grill: Put the seasoned, frozen Costco burgers directly onto the preheated grill grates. Ensure there’s enough space between the patties to promote even cooking and make flipping easier.
  3. Monitor and flip the burgers: Cook the burgers for about 15 minutes, flipping them every 3 to 5 minutes. Keep an eye on the burgers throughout the cooking process to avoid overcooking or charring.
  4. Check the internal temperature: Use a meat thermometer to ensure the burgers reach an internal temperature of 160°F before removing them from the grill. This is important for food safety and achieving the desired level of doneness.
  5. Toast the buns: While the burgers are cooking, take the opportunity to toast your hamburger buns on the grill for added flavor and texture.
