Grilled Peppers and Onions

These Grilled Peppers and Onions are smoky, sweet, and seriously addictive. Tossed in a bold, smoky spice blend and charred to perfection in a grill basket, they’re the ultimate fuss-free side. Serve them with your favorite grilled protein, pile them onto tacos, taco salads, burgers, or add them to bowls all week long. They’re tender, flavorful, and come together in under 20 minutes—just slice, season, and grill!

Equipment

Ingredients

  • 3 bell peppers, assorted colors, sliced into ½-inch strips
  • 1 large red onion, sliced into ½-inch strips
  • 1 Tablespoon avocado oil
  • 1 teaspoon EACH Morton kosher salt, cumin, chili powder, granulated garlic, onion powder, & smoked paprika

Instructions

  • Preheat & Season Veggies: Preheat your grill to high heat (about 450–500°F) and place a grill basket on the grates to preheat with the grill. In a large bowl, toss the sliced bell peppers, red onion, avocado oil, salt, cumin, chili powder, garlic, onion powder, and smoked paprika until well combined.

  • Grill: Carefully transfer the seasoned vegetables to the preheated grill basket. Grill for 12–15 minutes, tossing every 4–5 minutes, until the peppers and onions are tender and slightly charred in spots. Keep the grill lid closed between tosses to maintain high heat and achieve the best char.
  • Remove & Serve: Using heat-proof grill gloves, remove the hot basket from the grill and place it on a sheet pan to carry it inside safely. If you don’t have grill gloves, use tongs to scoop the grilled peppers and onions into a bowl, then allow the grill to cool completely before removing the basket.

Notes

  • Kosher Salt: All of my recipes are tested with Morton kosher salt unless noted otherwise. It is the best salt for everyday cooking because of its size and flavor. If using table salt, the amount should be reduced. I highly recommend picking up some kosher next time you are at the store!
  • Use a Grill Basket: It’s a game changer for veggies. No more losing half your peppers through the grates.
  • Don’t Skip the Toss: Stirring every few minutes ensures even cooking and prevents burning on one side.
  • Close the Lid: Keeping the grill lid shut between tosses helps trap heat and gives you that perfect char.
  • Don’t Overcrowd: Don’t pile the veggies too high in the basket. If you’re doubling the recipe, use two batches for the best char.
