Brats are always a good thing, but this Smoky Mustard Sauce for Brats makes them irresistible! It is the perfect way to turn your grill out into something special. This recipe isn't a finicky one, so feel free to adjust the flavors to your liking. It makes much more mustard sauce than you'll need for a small gathering, and that is not by accident. I love this sauce with other grilled meats, and it is fabulous over roasted vegetables.

Who else gets excited by grilling season?

Ok, truth be told I live in Florida. So grilling season is pretty much every day of the year except for the random two weeks scattered throughout the winter that it actually gets too cold.

This Smoky Mustard Sauce for Brats is so easy to make and really elevates your grill out. I love that it adds a touch of heat without being too hot for the kids.

This brat sauce is unbelievably good and you will find yourself wanting to put it on everything.

Need the brats to go with it? Here's how I make my Grilled Brats, on the grill or the Ninja Foodi. Then spoon this sauce over the top.

Ingredient Notes

Yellow Mustard: If you're feeling adventurous or just out of yellow mustard, feel free to substitute with Dijon mustard for a sharper bite.
Honey: Maple syrup can be a great alternative.
Apple Cider Vinegar: If apple cider vinegar isn't available, white wine vinegar or even lemon juice can serve as suitable substitutes, adjusting the sauce’s tanginess to your liking.
Smoked Paprika: In its absence, a bit more liquid smoke or a pinch of ground chipotle can mimic the smokiness.
Cayenne Pepper: Just a pinch for heat. If you're out or prefer less spice, omit it altogether. Add in 1 to 2 tablespoons of Sriracha for even more heat.
Coconut Aminos or Soy Sauce: This adds a layer of umami complexity. If you're avoiding soy and don’t have coconut aminos, tamari or Worcestershire sauce can be excellent alternatives.
Liquid Smoke: For that "just-off-the-grill" flavor. If you don’t have liquid smoke, increasing the smoked paprika slightly can help compensate, though the unique flavor of liquid smoke is hard to match.

Tips and Tricks

The Right Tools: A small, heavy-bottomed saucepan is your best friend here. It distributes heat evenly, ensuring your sauce cooks perfectly. And a silicone spatula? Perfect for scraping every last bit of sauce goodness from the pan.
Taste Test: I cannot stress this enough - taste as you go! Everyone’s palate is unique, so what's perfect for me might need a tweak for you. Be bold and adjust the seasonings to suit your taste buds. More honey? A dash more vinegar? Go for it!
Chill Factor: Once off the heat, give your sauce some rest time. This lets the flavors deepen and marry beautifully.
Serve It Your Way: While traditionalists might insist on bratwurst, don't let that limit you. This sauce is a star on burgers, a spicy kick in potato salads, and even a secret ingredient in your deviled eggs.

Serving

This is my go-to for a summer cookout, a Fourth of July spread, or a tailgate. It's just as good on my cast iron burgers, grilled chicken nuggets, or a scoop of potato salad, so I always make the full batch.
