Deliciously caramelized sauteed peppers and onions are a crowd-pleasing side dish for just about any meal! Made with herbs, seasonings and a splash of red wine vinegar. (gluten free, paleo, vegetarian, vegan)

Sauteed peppers and onions in a white bowl next to a clove of garlic and a striped blue and white cloth napkin.

Sauteed peppers and onions are the perfect side dish to go with just about every meal. Made from sweet bell peppers, red and yellow onions, a touch of olive oil and flavorful herbs and spices, this quick and easy vegetable recipe will add beautiful colors to you dinner plate.

And don’t even get me started on how healthy and nutritious they are. Just one serving of these veggies is filled with healthy fats, fiber and an impressive amount of vitamin C!

Besides the typical salt and pepper seasoning in most peppers and onions recipes, I’ve added in some red pepper flakes and dried oregano for extra flavor.

The end result isn’t spicy at all, so don’t worry if you’re sensitive to spicy foods. If you prefer a little spice, I recommend doubling the amount of red pepper flakes.

Tips and Tricks for the best peppers and onions

If the peppers and onions are starting to burn, turn down the heat on your stovetop just a little and adjust from there. We want caramelized peppers and onions, not burned peppers and onions.

If you’re not using a non-stick skillet, you may need to add in a little more olive oil. The veggies shouldn’t really stick to the bottom of the skillet, so add in more olive oil if needed.

Make sure to add in the minced garlic at the end so it doesn’t burn. If you add it in the beginning with all the seasonings, it’ll burn and that’s no bueno!

    These were really tasty, although I overcooked them a bit. Served with sauteed shrimp in a tortilla and delicious! These will be a staple to make quick side dish or combine with a vegetarian protein on hot summer days.

    Great vegetarian dish and good over rice or pasta.
    I de glazed with white wine and added coconut aminos for saltiness.
    Question where do you get hot peppers eg hotter than jalapenos?
    The jalapenos I buy in the store are not hot anymore.

    Delicious. I roasted some sweet peppers I bought at the farmers market in the oven at 350 for 15 mins and 380 for 15 minutes and it was delicious using this recipe. Put everything on the peppers from the outset before roasting. Must make again!

    I make this dish except that I add anchovies & chop them up as they are sautรฉed with the garlic. Sometimes I add black olives as well. Serve with Penne or any type of pasta

    Great way to spice up peppers and onions. Used these with a hot Italian sausage link from a local store and itโ€™s was great. My wife is vegan and she roasted some tomatoes and added it to the onion and pepper mix for her dinner and loved it. Said the vinegar gave it a nice burst of flavor also.

    Delicious!! Iโ€™ve made this recipe multiple times now because it is a hit. This time I had extra bell peppers that I didnโ€™t want to go bad so I made this and as usual, it was very tasty. I love how soft the peppers get and the flavor is very nice! Easy to pair with anything! Thank you for the delicious recipe! โค๏ธ

    You got it wrong in the first sentence. Never heat Olive oil to Medium-High heat. Use Peanut, Avocado or some other high-smoke point oil,,, and add a splash of Olive oil at the end if you want to add that taste. You know,,, Strip Mall Cooking School day 1 stuff.
