Hot Dogs with Onion & Stone Ground Mustard Relish

I LOVE tangy condiments on hot dogs – mustard, onions, pickles, sauerkraut – you name it. We took advantage of a few of those favorites to make a quick relish with our favorite grainy mustard, sweet onions and dill pickles.

We used a cast iron grill pan to grill our hot dogs indoors for a quick and easy weeknight dinner. Our favorite is this Lodge Grill Pan – the price is right and the pan comes PRE-SEASONED. Seasoning is by far the most time-consuming part of cast iron, but now we get the benefits without all the work (!!!).

Hot Dogs with Onion & Stone Ground Mustard Relish

  • Author: Kirsten Gjesdal


It’s hard to beat the classic combo of pickle relish, onions, and mustard on a hot dog – this onion & stone ground mustard relish takes that combo to the next level.


  • ½ cup Sweet Onion, chopped fine
  • ½ cup Pickles, minced
  • ¼ cup Whole Grain Mustard
  • Salt, to taste
  • 8 Hot Dogs
  • 8 Hot Dog Buns


  1. Make the relish: in a small bowl, toss together onion, pickles and whole grain mustard. Add salt and pepper to taste. Cover and refrigerate at least 30 minutes for flavors to meld.
  2. Grill the hot dogs: preheat a cast iron grill pan or a gas/charcoal grill to medium-high heat. Grill hot dogs on all sides until heated through. If desired, brush hot dog buns with butter and grill as well.
  3. Assemble hot dogs: place grilled hot dogs in buns and top with relish and any other toppings.
