Ingredients

The ingredients in this recipe are simple and straight forward. Just bell peppers, onions, oil and salt. No fancy herbs or spices needed to bring out the most incredible flavor in these. Just our special cooking method!

Peppers

I like a ratio of 2 bell peppers to one onion when I make this recipe. The recipe calls for one red bell pepper and one green bell pepper.

You can use any color you like, or two of the same color, but I enjoy the flavor contrast between the sweeter red pepper and the tangier green pepper. You will also find that yellow bell pepper, and orange bell pepper are sweeter like the red pepper, so they also make a good substitute.

Onion

Any variety of onion can be used in this recipe as well. I tend to gravitate toward sweet yellow onions because I love how they caramelize in the pan as they are sautéed. You can use yellow, white, or even purple onions. They will all work with delicious results in this recipe.

Oil

Oil is also something we can be flexible with in this recipe. Only minimal oil is used in sautéing to aid the cooking process. Since it is not used to add flavor to the dish, you can use what you have on hand and don’t have to worry about using a specific type of oil. I have used olive oil, vegetable oil and canola oil all with great success for sautéing. 

How to get the perfect sauté

The perfect sautéed onions and peppers have a slight char on the outside. The onions are translucent and sweet, and the peppers are starting to get soft but still hold their shape and have some substance to them.

What is sautéing?

To start with the basics, let’s talk about what makes sautéing unique from other cooking methods.

To sauté means to cook food quickly in a pan with a minimal amount of fat over medium-high to high heat. This method come from french cooking and originally traces back to the french verb sateur meaning to jump, which describes the food hitting the hot pan.

Sautéing Rules

To get this coveted perfection in cooking, there are a few specific things that need to happen.

1. Hot Pan– Don’t add the onions and peppers right away. First heat your pan to a medium high heat. Then add the oil and make sure your pan is hot and oil is heated before adding the vegetables. This helps to create the delicious caramelized outside.
   
2. Don’t over crowd your pan. If you put too many veggies in the pan, they will end up steaming instead of sautéing. You need some space in the pan for the liquid to cook off, otherwise it is trapped underneath the veggies and the steam that rises between them will cook them instead of the contact with the hot pan.
   
3. Let them sit– If you want the flavorful char on your peppers and onions it is important to let them sit without stirring for a bit (2-4 min) before stirring. This allows the char to form on the outside of the peppers and onions.
   
4. Use fresh veggies– Once vegetables are frozen the cellular structure will change and they can become too “wet” to get a nice sauté. So for the BEST results, use freshly cut bell pepper and freshly cut onion.

   You can however freeze onions and peppers that have already been cooked to thaw and eat later. See below for more details on that!

These four steps are the key to getting perfectly sautéed vegetables, so simple, yet if you skip one, you won’t get the same results.

Flavor Variations

This is the classic recipe for sauteed peppers and onions, however there are MANY great twists and flavor combinations that can build on this recipe. Here are a few things to try for a new flavor combination:

• Balsamic Peppers and Onions– To make these, follow the recipe as written and in the last minute of cooking time, stir in 2-3 teaspoons of balsamic vinegar to taste. This makes a great side for Italian style dishes or to pair with chicken or potatoes.
• Jalapeno Peppers and Onions– To spice it up, add jalapeños either cut in half or strips, that have been deseeded to the bell peppers and onions. Continue as directed. If you want it to be spicier, add a pinch or two of crushed red pepper to the mixture.
• Italian Peppers and Onions– Make recipe as directed. In addition to the salt, add in 1/2 teaspoon Italian Seasoning. Then in the last minute of cooking time, stir in 2-3 teaspoons of balsamic vinegar to taste and allow it to cook down.

How to Freeze Sautéed Bell Peppers & Onions

If you have leftovers of this recipe or like to prep ahead or batch cook, these sautéed peppers and onions can be kept in the refrigerator for up to 5 days, or frozen to extend the life.

Freezer instructions

1. Prepare sautéed peppers and onions as directed in recipe card.
2. Allow to cool to room temperature.
3. Divide into meal sized portions (if desired) then package in zip top bag or other freezer friendly container.
4. Freeze.
5. When ready to use, thaw overnight in the refrigerator.

Note: making sautéed onions and peppers from frozen packages of peppers and/or onions can work but is more difficult since the vegetables release more moisture after they have been frozen. I recommend cooking them before freezing for the best results.
