Ingredients

Instructions

  1. Step 1: Prepare a charcoal grill for medium heat. While the coals heat, melt 3 tbsp unsalted butter with 1 tbsp olive oil in a large skillet over medium-low heat. Add 2 large thinly sliced yellow onions, 1/2 tsp salt, and 1/4 tsp black pepper. Cook slowly, stirring occasionally, for 25-30 minutes until onions are deeply golden and caramelized.
  2. Step 2: Place 8 all-beef hot dogs on the grill and cook for 5-7 minutes, turning occasionally, until heated through with nicely charred grill marks.
  3. Step 3: Lightly toast 8 hot dog buns on the grill for 1-2 minutes until warm and slightly crispy.
  4. Step 4: Place each grilled hot dog into a toasted bun, top generously with the caramelized onions and 1 tbsp yellow mustard per hot dog. Serve immediately outdoors for a classic picnic favorite.

How do I store leftover Charcoal-Grilled Hot Dogs with Caramelized Onions and Mustard?

Can I substitute ingredients in Charcoal-Grilled Hot Dogs with Caramelized Onions and Mustard?
