How to grill veggies on a propane grill

Grilling vegetables on a propane grill is a delicious way to add flavor to your veggies. Here's a step-by-step guide on how to do it from Papa Ken at Maine Grilling Products.


  • Assorted vegetables (e.g., bell peppers, zucchini, mushrooms, onions, asparagus, corn, etc.)
  • Olive oil or vegetable oil
  • Salt and pepper
  • Optional: your choice of seasonings or herbs (e.g., garlic powder, paprika, rosemary, thyme)



  1. Preheat the Grill:

    • Turn on your propane grill and preheat it to medium-high heat (around 350-450°F or 175-230°C). This will ensure your grill is hot enough to cook the veggies quickly and give them a nice char without overcooking.
  2. Prepare the Vegetables:

    • Wash and dry the vegetables. If you're grilling small or delicate veggies like cherry tomatoes or green beans, consider using a grill mat or placing them on a sheet of aluminum foil to prevent them from falling through the grates.
    • Cut the vegetables into uniform sizes to ensure even cooking. For example, slice bell peppers, zucchini, and onions into rings or strips. Leave asparagus spears whole or trim the tough ends.
  3. Season the Vegetables:

    • Drizzle the vegetables with olive oil or vegetable oil to prevent sticking and promote even grilling.
    • Season the veggies with salt, pepper, and any other seasonings or herbs you like. Garlic powder, paprika, rosemary, and thyme are great choices for added flavor.
  4. Grill the Vegetables:

    • Place the vegetables directly on the preheated grill grates or on the aluminum foil if using.
    • Cook the vegetables, turning them occasionally, until they develop grill marks and become tender. The cooking time will vary depending on the type and size of the vegetables, but most will take about 5-15 minutes.
    • Here's a general guideline for a few common vegetables:
      • Bell peppers, zucchini, and onions: 5-8 minutes
      • Asparagus and mushrooms: 8-10 minutes
      • Corn on the cob: 15-20 minutes (turning occasionally)
    • Use your tongs to flip and move the veggies around as needed to prevent burning.
  5. Check for Doneness:

    • Vegetables should be tender and have a nice char, but still slightly crisp. Test with a fork or a knife to ensure they're cooked to your desired level of doneness.
  6. Serve:

    • Remove the grilled vegetables from the grill and transfer them to a serving platter.
    • Optionally, garnish with fresh herbs or a squeeze of lemon juice for extra flavor.
  7. Enjoy:

    • Serve your grilled vegetables as a side dish, in salads, on sandwiches, or as a topping for burgers and wraps. They make a versatile and tasty addition to many meals.

Remember that the cooking times may vary, so it's essential to keep a close eye on your vegetables as they grill to avoid overcooking. With practice, you'll become a grilling pro and create perfectly grilled veggies every time. Enjoy! Papa Ken
