3-Ingredient French Onion Burgers

beef

1-ounce envelope onion soup seasoning mix

Worcestershire sauce

Morton coarse kosher salt

sweet onions, thinly sliced

olive oil

unsalted butter

Morton coarse kosher salt

balsamic vinegar

mayonnaise

Dijon mustard

garlic,

Morton coarse kosher salt & ground black pepper,

Prep

Prepare the grill for medium-high direct grilling, 450-500 degrees F. Prep any toppings &amp; condiments as desired (see below). 

Mix &amp; form the burger patties

Add the ground beef, onion soup seasoning mix, Worcestershire sauce &amp; kosher salt to a large mixing bowl. Using your hands, mix just until well combined. Be careful not to overmix as it yields a dryer, tougher burger. Divide the mixture into 4 equal portions. Press each portion into a 1-inch thick burger patty. Use your thumb to press a slight indent in the center of each burger patty. 

Grill the burgers: 

Place the burger patties on the grill grates, directly over the flame. Grill 3 minutes per side for medium doneness. If you prefer a less/more done burger, grill for 1 minute less/more. If making a cheeseburger, add the cheese to the burger patties in their last minute of grilling. Toast the St Pierre Brioche Burger Buns while you&#8217;re at it &#8211; see below!

Serve the French onion burgers: 

Build your burgers as desired. At our house, the toasted St Pierre brioche buns get a quick schmear of Dijonnaise, topped with leafy lettuce, a French onion burger, crispy bacon, &amp; caramelized onions. Serve immediately. Enjoy! 

Toasted St Pierre Brioche Burger Buns

Lightly spritz the buns with nonstick cooking spray. In the final minute or so of grilling the burgers, place the buns on the grill grates over direct heat. Cook for 1 minute or so, until as toasty &amp; crisp as desired. Remove from the grill &amp; serve immediately. 

Dijonnaise

Add all listed ingredients to a small bowl, whisking to combine. Feel free to add a hint of honey for some honey-mustard vibes, or a dash of your favorite spice blend. Set aside, or store in an airtight container in the refrigerator for up to 5 days. 

Easiest Crispy Bacon

Preheat the oven to 375 degrees F. Line a large baking sheet with aluminum foil for easy clean-up. Place the bacon on the prepared baking sheet. Bake for 10-12 minutes, until the rendered &amp; crisp as desired. Remove from the oven &amp; transfer the bacon to a paper towel-lined plate. Serve immediately or store in an airtight container in the refrigerator for up to 5 days. 

Caramelized onions: 

Place the olive oil &amp; butter in a large pan over medium-high heat. Once the butter is melted, add in the onions. Season with kosher salt &amp; toss to coat in the oil. Reduce the heat to low. Cook for 45-60 minutes, stirring occasionally, until the onions are deeply brown &amp; caramelly. In the last 5-10 minutes of caramelizing, deglaze the pan with the balsamic vinegar. Remove from the heat &amp; serve immediately or store in an airtight container in the refrigerator for up to 5 days.
