This easy steak recipe lets the kids get involved in making a flavorful mustard seed crust that’s perfect for grilling. It’s a fun and tasty Father’s Day meal they can prepare with some supervision.


  • 4 beef steaks (ribeye, strip steak or dad’s favorite cut)
  • 1/4 cup olive oil or vegetable oil
  • Mustard Seed Rub (recipe below)

Mustard Seed Rub

  • 2 tablespoons yellow mustard seeds
  • 1 tablespoon arugula seeds
  • 1 tablespoon radish seeds
  • 2 teaspoons coriander seeds
  • 2 tablespoons coarse kosher salt
  • 1 tablespoon brown sugar
  • 1 teaspoon black pepper
  • 1 teaspoon smoked paprika
  • 1/2 teaspoon garlic powder


  1. Make the Mustard Seed Rub: In a dry skillet, have kids toast the mustard, arugula, radish, and coriander seeds for 1-2 minutes until fragrant. Let cool completely.
  2. Using a ziplock bag, Let kids gently crush into a coarse powder using a spoon or rolling pin. OR Transfer seeds to a spice grinder to pulse into powder.
  3. In a bowl, let kids mix the ground seed powder with the salt, brown sugar, pepper, smoked paprika and garlic powder.
  4. Rub the steaks all over with the olive oil or vegetable oil.
  5. Have kids generously coat both sides of the steaks by pressing the mustard seed rub mixture onto the meat.
  6. Let the rubbed steaks rest for 30 minutes before grilling.
  7. Grill the steaks to dad’s desired doneness, flipping once halfway through cooking time.

Let the kids get creative by making handwritten labels for the rub jars as a gift for dad. Serve the mustard-crusted steaks with dad’s favorite grilled veggies or a fresh salad for a flavorful Father’s Day meal he’ll love!
