Step-by-Step Instructions for Smoked Onion Soup Burgers:

The full step-by-step instructions, along with ingredients, can be found in the printable recipe card below.

1. Set up the smoker to 225 degrees F.
2. Add the ground beef to a bowl and mix in the onion soup mix.
3. Make your burger patties and measure 8 ounces of ground beef per patty. Shape the ground beef into patties about 1/2 inch thick. (Make them smaller and make more burgers if preferred.)
4. Place the burger patties onto the smoker grill grate and smoke until the internal temperature reaches 135 degrees F. (Usually takes up to an hour, depending on the thickness.)
5. Increase the temperature of the smoker to 450 degrees F. Once this has been reached, quick sear the patties on both sides for 2-3 minutes. Add cheese slices after the last flip if desired.
6. Burgers are done when the internal temperature reaches 165 degrees F.
7. Serve with your favorite toppings!

What pellets should you use?

For a smoky, bold flavor, use hickory or mesquite. A wood blend will work well, such as a blend of hickory, oak, and mesquite. Cherry and Apple are best avoided as they may make the burgers a bit too sweet.

Tips for Making Smoked Onion Soup Burgers:

• Always use 80/20 Ground Beef – DO NOT use any leaner ground beef than 80/20, or it will dry out during the smoking process. It’s best to use 80/20 ground beef to keep the burgers juicy during the smoking process.
• Chill Before Cooking – This is not necessary, but if you are concerned about the burgers holding their shape, chill the ground beef for 30 minutes in the fridge after forming the patties.
• Use a Meat Thermometer – Use a probe or meat thermometer to monitor the temperature of the ground beef. The burgers will be smoked until they reach an internal temperature of at least 135 degrees F then they will be seared at a higher heat.
• Get creative with toppings – Add some crispy onions on top or a variety of cheese like pepperjack.
• Rest before serving – Let the burgers rest for 2-3 minutes before serving to let the juices redistribute throughout the burgers.
• For smaller burgers – This recipe is made into 4 larger patties with 2 pounds of ground beef. It is simple to use the 2 pounds to make 6 burgers instead if you prefer smaller burgers.
• Make on any Pellet Grill – These can be made on any pellet grill, like a Traeger. We use a Green Mountain Pellet Grill.

How do you store leftover smoked hamburgers?

Once fully cooled, store leftovers in an airtight container in the fridge for up to 3 days. When ready to serve, air fry at 350 degrees F for 4 minutes or place in the microwave on a microwave-safe plate for 1-2 minutes.

Remember, these are best served fresh.

Smoked Onion Soup Burgers on the Pellet Grill add the best savory flavor and are simple enough to make during the week or for a cookout. Once you have a smoked burger, it will be a favorite on your menu. Be sure to try these traditional pellet grill burgers and smoked mushroom Swiss burger too!
