Here’s how to make a summer meal in no time: grilled peppers and onion! Fire up your grill for the main event, and toss these babies on the side. These colorful veggies transform into the most incredibly flavorful side dish: they’re tender, charred, smoky, and sweet all at once. Peppers and onions are one of Alex and my absolutely favorite things to throw on the grill for summer meals. But we didn’t write down the recipe, until now! Here’s how to make this treat pairs well with all the grilled dinner ideas, be it salmon, shrimp, tacos or portobello burgers.

Ingredients for grilled peppers and onion

The great thing about grilled peppers and onion is: they taste incredible with almost no seasonings! You need no fancy spice blends for this one. Just good old salt! Here’s what you’ll need:

3 bell peppers: we like using multi-colored for a splash of color
Red onion
Olive oil
Kosher salt

How to make grilled bell peppers and onion: in a grill basket

You’ll need a grill basket (or aluminum foil) for this method. Why? The onion in particular is so thin that it tends to fall through the grates if you place it on them directly. A grill basket keeps all the veggies together and heats them evenly. Here are some tips on how to do it (or go right to the recipe):

Make sure to preheat the grill basket on the grill!
Slice the peppers and onion into thick strips: about 1 ½ inches thick. Mix with olive oil to coat and salt.
Grill about 10 to 15 minutes, until the veggies are charred and tender. Toss them a few times to ensure even cooking. That’s it!

Use aluminum foil if you don’t have a grill basket!

Don’t have a grill basket? No problem. Here’s the grill basket we use, if you’d in the market for one. Or you can make a make-shift grill basket out of aluminum foil! Here’s what to do:

Fold a large piece of aluminum foil in half and prick several holes in it with a fork.
Fold up a 1-inch rim around the edge to make a makeshift tray. This isn’t required, but it’s helpful to keep all the veggies in the tray. Then you can use it like you would a grill basket!

Variations on grilled peppers and onion

You can vary up the seasonings on these grilled peppers and onion as much as you’d like! They’re beautifully sweet and tender without extra seasoning. But there are endless variations! Here are some ideas:

Cumin and lime. Add a hint of cumin before grilling (¼ teaspoon), then spritz with fresh lime juice.
Taco seasoning or fajita seasoning. Make them fit for a Mexican-style feast.
Cajun seasoning. Love heat? Sprinkle with a little Cajun seasoning before or after grilling.
Old Bay. Add big flavor with a little shake of Old Bay seasoning.
