Grilled Vegetable Marinade

  • 4 ounces unsalted butter diced (if Paleo or Whole30, use clarified butter)
  • 1/3 cup shallots chopped
  • 1/3 cup olive oil
  • 3 Tablespoons Dijon mustard
  • 4 Tablespoons lemon juice about 1
  • 1 Tablespoons lemon zest
  • 2 Tablespoons fresh thyme chopped
  • Kosher salt and black pepper to taste

Vegetables for Grilling

  • 2 onions sliced 1/4" thick
  • 2 zucchini sliced vertically, 1/4" thick
  • 3 bell peppers cut into quarters
  • 1 bunch asparagus spears ends trimmed
  • 1/2 pound mushrooms brown, white or 2 portabellos
  • 3 carrots sliced vertically or into wedges


Grilled Vegetable Marinade

  • Combine all ingredients in a heavy sauce pan. Whisk over medium heat until butter melts and sauce is well blended.
  • Season to taste with salt and pepper. (Can be made 3 hours ahead. Cool. Whisk over low heat to rewarm before using.)


  • Cut zucchini, carrots and onions about 1/4" thick.
  • Slice bell peppers into quarters
  • Skewer the mushrooms if using small mushrooms or remove tough center stem if grilling portobello mushrooms.
  • Brush both sides of veggies with marinade. They can be wrapped and refrigerated if making them ahead. Remove from fridge about 30 minutes before grilling.
  • Over a medium heat, begin grilling vegetables starting with thickest vegetables first (carrots) and end with the most delicate last. (Asparagus needs just a few minutes)
  • If there's extra sauce, reheat it and serve it on the side or drizzle over warm vegetables.
