Ingredients

• 2/3 cup mayo
• 2 tbsp. ketchup
• 2 tbsp. brown mustard
• 2 tsp Worcestershire
• 1/2 cup fresh parsley, chopped
• 2 lbs. ground beef
• 1/2 beef bouillon cube, finely crumbled
• 1/2 tsp kosher salt
• Black pepper, to taste
• 6 tbsp. salted butter
• 2 large onions, thinly sliced
• 16 oz. package frozen sweet potato fries
• 1 tbsp. olive oil
• 1 tsp garlic salt
• 1/2 tsp paprika
• 6 sesame burger buns, toasted

Directions

1. Mix the mayo, 1 tbsp. each ketchup and mustard, 1 tsp Worcestershire and the parsley in a medium bowl. Refrigerate until ready to serve.

2. Combine the beef, crumbled bouillon, salt, black pepper, the remaining 1 tbsp. each ketchup and mustard, and the remaining 1 tsp Worcestershire in a large bowl. Use your hands to mix until just combined. Divide the mixture into 6 equal balls, then press into patties. Place on a parchment-lined baking sheet and set aside.

3. Melt the butter in a large skillet over medium heat. Add the onions and cook, stirring occasionally, until softened and browned, 13-15 minutes. Remove the onions to a plate.

4. Meanwhile, preheat the oven to 450. Toss the fries with the olive oil, garlic salt and paprika on a baking sheet; spread in an even layer. Bake until crispy, 22-25 minutes.

5. Preheat a grill or grill pan to medium high. Grill the burgers until well marked, 4-5 minutes per side for medium rare. Spread a heaping tbsp. of the mayo mixture on both sides of the buns. Put the burgers on the buns and top with the onions. Serve with the fries.
