- Olive oil – Use your best extra virgin olive oil, since it’s the flavor base of this great side dish.
- Bell peppers – Use a mix of red bell peppers, green bell peppers for color and crunch. You could also use orange bell peppers and/or yellow bell peppers.
- Onions – I prefer to use yellow onions, but you could substitute white onions. If you use red onion, just know that they can add a sharper, slightly different flavor to the dish.
- Garlic – Be sure to add the minced garlic toward the end so it won’t burn.
- Herbs – I prefer to use thyme, which adds a rich, earthy flavor to the dish. Then I finish it off with a sprinkling of chopped fresh parsley. But you could also substitute rosemary, fresh basil, or oregano for the thyme. Or, try using a combination of herbs, homemade fajita seasoning, or Italian seasoning.
- Salt & pepper – Use kosher salt and ground black pepper to season the dish.

👩🏻🍳 Cooking tips and recipe FAQs
Choose fresh, firm peppers and onions. The fresher the vegetables, the better the flavor and texture.
Start with medium-high heat to get a good sear and caramelization on the vegetables. This helps bring out their natural sweetness and adds a slightly smoky flavor.
Garlic can burn quickly, so be sure to add it last, just before the herbs & seasonings. Once you add it, watch it carefully to ensure it doesn’t burn.
Try adding garlic powder, onion powder, and red pepper flakes for a bit of a kick. You can also sauté the peppers and onions with some Italian sausage. Or try drizzling some balsamic vinegar just before serving.
Allow the vegetables to cool down. Then store them in an airtight container in the refrigerator for up to 4 days.
